4.0 Nature and Extent of Contamination

This chapter presents a discussion of the concentrations and spatial distributions of the chemical

compounds detected at the SRI site. The areas of investigation were identified based on previous

field investigations conducted by Dames & Moore (1988) and Velzy/West.on (1990). The IT

sampling program was designed to focus on the areas that required further site investigation and

characterization.

This chapter has been organized into four sections. Section 4.1 discusses the potential sources

of contaminants at the SRI site. Section 4.2 presents the results of the soil investigation program.

The soil investigation explored the areas of suspected soil contamination, as well as determined

the nature and extent of soil contamination throughout the site. Section 4.3 discusses the results

of the groundwater investigation and evaluates possible sources for the contamination, as well

as delineates horizontal and vertical contamination present in the site overburden and bedrock

aquifers. A discussion of the water quality of nearby residential wells is also included in this

section. Section 4.4 presents the results of the sediment and surface water investigation

performed at the SRI site.

The data used in this nature and extent of contamination evaluation consist of analytical results

obtained by IT during the Phase I investigation conducted in the Fall of 1992 and the Phase II

investigation conducted in the Fall of 1993. Tables 4-1through4-39 summarize the constituents

detected in the wast.e material, soils, groundwater, surface water, and sediment of the SRI site.

Figure 2-3 presents the locations of the environmental media samples collected as part of this RI.

In addition, residential well sampling analytical results from the New Y oik State Department of

Health (NYSDOH) has been included in Section 4.3.3.

All of the RI analyses were performed by BP A-approved laboratories under the Contract

Laboratory Program (CLP) and have been validated by Ebasco and approved by BP A. Results

of these validators' scrutiny are data sets with qualifiers that describe the quality of the data

strictly from an analytical chemistry quality assurance viewpoint. Data with the following

qualifiers were included as detected concentrations in their respective media:

"J" estimated concentration;

"B" - (inorganic data) compound detected above instrument detection limit but below the contract required detection limit;

(organic data) indicates detection of the same compound in the associated blank;

presence of interference for inorganics or exceedence of a calibration range of the GC,MS instrumentation for organics;

analysis conducted at a secondary dilution factor;

duplicate injection precision was not met;

spiked sample recovery was not within control limits;

duplicate analysis is not within control limits;

correlation coefficient for the Method of Standard Additions is less than 0.995; and

Post-digestion spike is not within control limits.

Data reported as not detected, indicated by a "U" qualifier, were not included in the database.

Data with an "R" qualifier, indicating a rejected value, were not included in the database. All

other data, regardless of the respective qualifier are considered in the development of the

database.

The objective of the RI is to determine the natme and extent of contamination sufficiently to ( 1)

perform a baseline risk assessment, and (2) develop and evaluate remedial action alternatives.

The data acquisition phase of the RI focused on obtaining the proper quality and quantity of data

necessary to meet these two RI objectives.

Conclusions regarding the nature and extent of constituents present in the environmental media

are based on the data collected during this RI and previous studies. The purpose of this RI is

to confirm the presence of suspected contaminants and delineate their extent.

4.1 Potential Contaminated Media

The original sources of contamination on the SRI site were located within the former disposal

cell, the drum storage area, the landspreading areas, the waste storage tank, and the tanker trailer

(Figure 2-1). As a result of the three remedial actions already implemented at the SRI site

(Section 1.2), much or most of the contamination sources associated with the former disposal cell,

the drum storage area, the waste storage tank, and the tanker trailer have been remediated. As

discussed in detail in the Dames & Moore RI/FS report (1988) and the Velzy/Weston final report

EDIS/ENG/ay071494.rp4 4-2 (""i ! : . ·" ..

( 1990), these waste sources consisted largely of drummed organic liquids (including petroleum

derivatives and chlorinated solvents) and soils contaminated with these liquids. Table 4-1 lists

the wastes disposed at the former disposal cell. Tables 4-2 and 4-3 contain the results of the

analyses of the contents of the waste storage tank and the tanker-trailer, respectively. Table 44

lists the contaminant levels detected in two waste samples collected from the site during the

Dames & Moore RI/FS investigation (1988). Table 4-5 lists the analysis of water samples taken

from the disposal pit as well as other water samples collected during 1980. All known drums,

all tank liquids, and much of the contaminated soils have been removed from the site (Section

1.2.2). However, based on the Velzy/Weston results, some contaminated soils still remain in the

disposal area and possibly in the drum storage area.

As part of this RI groundwater sampling investigation, the leachate collection system situated

within the former disposal cell area was sampled and analyzed for full TCL and TAL parameters.

Concentrations of a number of chlorinated volatile organic compounds (ie., 1,1,1-trichloroethane

[l,1,1-TCA], 1,1-dichloroethane [1,1-DCA], trichlorothene [TCE], tetrachloroethene [PCE], cis-

1,2-dichloroethylene [cis-1,2-DCE] and vinyl chloride [VC]) ranging in concentrations from

8 pg/L to 1200 pg/L were detected in the cell's leachate (Table 4-6). The pesticide endrin

aldehyde was also detected in the leachate sample. Magnesium was the only elevated inorganic

analyte above proposed cleanup criteria. No semivolatile organic compounds or PCBs were

detected in the leachate sample.

The large landspreading areas shown in Figure 2-3 were sprayed with PCB and metal

contaminated soils and have not been remediated to date (Dames & Moore, 1988). Table 4-7

lists the type of waste fluids spread over the landspreading areas.

In summary, many of the original and most concentrated sources of contamination on the site

have been removed. However, contaminated soils associated with the landspreading areas and

some of the soil associated with the former disposal cell area and drum storage area still remain

on site. These soils are potential sources of contamination to the surface water and sediments

via lateral overland flow into the wetland areas, as well as a potential source of groundwater

contamination via vertical migration into the overburden and bedrock aquifers. These

contaminated soils are discussed in Section 4.2.

4.2 Soils This section describes the nature and extent of contamination in the soils at the SRI site. Sixteen

locations were sampled using hand auger samplers which were advanced to a maximum of 2 feet

below grade to collect one shallow soil sample for each hole. Twenty-one locations were

sampled using split-spoon samplers. Samples were collected intermittently from surface grade

to a maximum of 43 feet below ground surface, dependent on organic vapors screening results

and preassigned sample intervals. Section 2.6 discusses the soil sampling techniques and

methodologies in detail. Figure 2-2 presents the soil sampling locations. The main focus of the

soils investigation was the former disposal cell (6 sample locations), gravel pit (5 sample

locations), disposal tank (1 sample location), and landspreading areas (22 sample locations). A

total of 96 soil samples were collected at the SRI site as part of this RI.

The soil samples collected were analyzed for full TCl./f AL parameters, including volatile

organic, semivolatile organic, pesticide, PCB, and inorganic analyses (including cyanide). Tables

4-8 through 4-15 present the summary of compounds detected in the soil samples. Appendix A

presents the detailed analytical results.

Figures 4-1 and 4-2 present the surface soil (0-3 feet) sampling locations and corresponding

organic analytical data.

The detected constituent concentrations were compared against the most stringent ARAR

in order to determine potential contaminants in the soils at the SRI site (Table 4-16).

Volatile Organic Compounds. Eight volatile organic compounds (VOCs) were detected in

a minimal number of soil samples collected from the SRI site. Table 4-8 and Table 4-9 present

the results of the volatile organic analyses for the surface and subsurface soil samples,

respectively. The VOCs which were most frequently detected is surficial soils (0-3 feet) were

acetone (8 detected values out of 42 samples ranging from 5.5 µg/kg to 82 µg/kg), 2-butanone

(7 samples ranging from 7 µg/kg to 12 µg,lkg) and methylene chloride (12 samples ranging from

13 µg/kg to 61 µg/kg). All three of these compounds are common laboratory contaminants

Remedial/Response, USEPA, Washington, D.C. 20460, April 1992, 9285.7-09A).

In addition, the voes chloroform (4 samples ranging from 1 µg/kg to 2 µg/k:g), 1,1,1-

trichloroethane (3 samples: borings SB-06 at 10-12 ft, SB-08 at 2-4 ft and SB-17 at 18-20 ft; at

3 µg/kg, 7 µg/kg and 17 µg/kg, respectively), toluene (2 samples at 1 µg/kg and 9 µg/kg, both

in boring SB-15 at 18-20 ft and 6-8 ft, respectively), 1,1-dichloroethane (boring SB-18 at 2

µg/kg [14-16 ft]), and total xylenes (boring SB-15 [6-8 ft] at 3 µg/kg) were also detected in the

soil samples.

The majority of the volatile organic contamination appears to be located within the saturated

subsurface soil in the vicinity of the former disposal cell area, in particular, boring locations SB-

17 and SB-18. Acetone concentrations exceeded their respective "soil cleanup objective levels"

in these two borings. None of the other potential source areas (i.e., landspreading area, drum

storage area, gravel pit, or waste storage tank area) or the areas between source areas contained

substantial levels of voes.

Semivolatlle Organic Compounds. A total of 20 semivolatile organic compounds were

detected in the soil samples. Tables 4-10 and 4-11 present the results of the semivolatile organic

analyses for the surface and subsurface soil samples, respectively. The most frequently detected

semivolatiles were bis(2-ethylhexyl)phthalate (59 samples ranging from 34 µg/kg to

2,100 µg/kg) and di-n-butyl phthalate (9 samples ranging from 23 µg/kg to 48 µg/kg). Both of

these compounds are common laboratory contaminants (USEPA, 1992}. The majority of the

remaining 18 detected semivolatile organic compounds are polycyclic aromatic hydrocarbons

(PAH). PAHs were detected in a minimal number of samples (i.e., 14) in concentrations ranging

from 17 µg/kg to 710 µg/kg. The majority of these P AH compounds were detected within the

top 3 feet of soil in the vicinity of the former disposal cell area; in particular, soil borings SB-14,

SB-15, SB-18, SB-19, SB-20, and SB-21.

The highest total semivolatile organic concentration (1753 mg/kg) was detected within the 1 to

3 foot sample depth interval of location SB-18, located adjacent to the northeast comer of the

disposal cell. Bis(2-ethylhexyl)phthalate, di-n-butylphthalate, 4-methylphenol, diethylphthalate,

phenanthrene, anthracene, fluoranthene, pyrene, benzo(a)anthracene, and chrysene concentrations

exceeded their respective NYSDEC "soil cleanup objective levels" in this boring. These were the

only semivolatile compounds to be in exceedance of NYSDEC "soil cleanup objective levels."

Pesticides and PCBs. Seventeen pesticides were detected at low concentrations (0.022 µg/kg

-170 µg/kg) in the surface and subsurface soils of the SRI site (Tables 4-12 and 4-13,

respectively). The most frequently detected pesticides were heptachlor epoxide (10 samples), 4,4'

DDT (9 samples) and heptachlor (8 samples). The majority of the pesticide contamination was

present within the zero to 2-foot interval. The highest pesticide concentrations were present in

the drum storage area, at locations HB-03 and HB-04.

It is not unexpected that pesticides would be present at the SRI site since the area has been used

for agricultural purposes in the past. The detected pesticides are very persistent in the

environment and concentrations would be present in soils for many years after application.

Based on site history, pesticides were not known to have been disposed at the site as part of

normal disposal operations.

Four PCB compounds were detected in 6 separate surface (i.e., zero to 3 feet) soil samples.

Aroclor-1254 was detected in the most samples (i.e., 3) in concentrations ranging from 5.4 µg/kg

to 22 µg/kg. Only boring locations SB-01 (13 pg/kg), MW-03D (22 µg/kg), and MW-05S (5.4

µg/kg) exhibited detected concentrations of aroclor-1254. In addition, aroclor-1221 (SB-21 at 72

µg/kg), aroclor-1260 (SB-06 at 29 µg/kg) and aroclor-1016 (MW-OlD at 1.6 µg/kg) were

detected in the soils at the SRI site.

No pesticides or PCBs exceeded their respective NYSDEC "soil cleanup objective levels."

Inorganic Analytes. In order to assess site-related inorganic contamination, the soil samples

were compared against the results of the two background soil borings (i.e., HB-01 and MW-010).

This comparison was used to determine if the concentrations of inorganic analytes detected in

the soil samples were elevated above naturally occurring background concentrations indigenous

to the area. Table 4-16 presents the inorganic data collected from soil sample locations HB-01

and MW-OlD.

Twenty of the 24 inorganic constituents analyzed for were detected in concentrations above

background levels. The only constituents not detected above background levels were cadmium,

selenium, thorium, and cyanide (see Tables 4-14 and 4-15).

The two most predominant inorganic constituents detected were calcium and magnesium. This

is expected due to the dolomitic bedrock subsurface environment which is composed mostly of

(Ca,Mg) C03.

The sample location which exhibited the highest number of elevated constituents above

background (i.e., 8) in the surface soils (zero to 3 feet) was MW-OlD. In addition, three

locations showed elevated levels above background of at least four constituents each (Table 4-

14). These locations are HB-03 and HB-04 (both located near the drum storage area) and HB-13

(located in landspreading area C).

Within the subsurface soils (>3 feet), the locations exhibiting the most elevated inorganic analytes

above background were SB-19 (15 analytes at 31 to 33 ft) and SB-20 (12 analytes at 23 to 24 ft),

both located south of the former disposal cell area (Table 4-15). In addition, two other sample

locations present in the vicinity of the former disposal cell area exhibited elevated inorganic

constituents above background, SB-16 (11 analytes at 16 to 18 ft) and SB-18 (9 analytes at 30

to 31 ft). Table 4-16 presents state, federal and clean-up criteria, as well as background

analytical soil data.

Common elevated inorganic analytes above background were calcium, magnesium, manganese,

and lead. Since only two background samples have been collected, a thorough statistical analysis

has not been performed. Thus elevated concentrations above background may not be truly

indicative of actual soil contamination.

Soils Summary. Concentrations of volatile organic compounds ranging from 1 µg/kg to

80,000 µg/kg were detected primarily within the subsurface soils located in the vicinity of the

former disposal cell area. The highest VOC concentrations were detected at soil boring locations

MW05 and MW5A. A number of PAHs were detected in the surface soils in the vicinity of the

former disposal cell area in concentrations ranging from 17 µg/kg to 710 µg/kg, as well.

Concentrations of pesticides were detected in the surface soils situated near the drum storage area

ranging from 0.07 µg/kg to 170 µg/kg. Six isolated surface.samples (MW-010, MW-030, MW-

05S, SB-01, SB-06, and SB-21) exhibited low concentrations of PCBs ranging from 1.6 µg/kg

to 72 µg/kg.

Elevated levels of a number of inorganic constituents above background were detected in the

surface soils, primarily in the vicinity of the drum storage area and landspreading areas J and C.

Within the subsurface soils, the greatest amount of inorganic contamination was present in the

vicinity of the former disposal cell area at depths ranging from 16 to 34 feet below grade. The

main elevated inorganic constituents above background were calcium, magnesium, manganese,

and lead.

Soil contamination was not found in the waste storage tank area, gravel pit and landspreading

areas.

4.3 Groundwater

This section discusses the nature and extent of contamination present in the groundwater in the

vicinity of the SRI site. The RI groundwater investigation was conducted in two phases. Five

open-bedrock wells (MW-010, MW-02, MW-030, MW-04, and MW-050) and three overburden

wells [MW-OlS, MW-03S and MW-05S (renamed MW-05SA during Phase II activities)] were

installed during the first phase of the investigation. An additional three bedrock wells (MW -

060, MW-070, and MW-090) and seven overburden wells (MW-06S, MW-061, MW-07S, MW-

071, MW-08S, MW-05S, and MW-051) were installed during the second phase. The first round

of groundwater sampling was conducted in November 1992 and the second round of sampling

was conducted in October 1993. In addition to the newly installed RI wells, 19 overburden wells

installed at the site under previous field investigations were sampled as part of both the Phase

I and Phase II RI groundwater investigations. A total of 17 private residential wells in the

vicinity of the SRI site were sampled and analy7.Cd as part of the Phase I investigation and

23 residential wells were sampled and analyzed as part of the Phase II investigation. In addition

a stone-lined hand-dug well (HD-01) and the fonner disposal cell's leachate system (LS-0 l) were

sampled during the Phase I and Il investigations. Section 2. 7 discusses the groundwater

investigation field sampling techniques and methodologies in detail.

Section 3.7.2 discusses the SRI site geological characteristics and Section 3.8.2 discusses the SRI

site hydrogeological characteristics in detail. Figure 2-2 presents the groundwater sampling

locations. Tables 4-17 through 4-20 present the summary of compounds detected in the

groundwater samples colleeted from the overburden monitoring wells. Tables 4-21 through 4-23

present the summary of compounds detected in the bedrock monitoring wells. Tables 4-24

through 4-27 present the summary of compounds detected in the residential wells during RI

sampling. Tables 4-28 through 4-31 present the summary of compounds detected during the

NYSOOH residential well sampling program.

The groundwater samples collected as part of this RI were analyzed for full TCl./f AL

parameters, including volatile organic, semivolatile organic, pesticide, PCB, and inorganic

analyses (including cyanide). Both filtered and unfiltered groundwater samples were analyzed

for inorganic parameters. Appendix A presents the full groundwater laboratory analytical results.

The concentrations of each detected constituent were compared against both the NYSDEC

"Ambient Water Quality Standards and Guidance, October 1993" (NYSDEC, 1993) for Class GA

drinking waters and the federal Safe Drinking Water Act (SOWA) Maximum Contaminant

Levels (MCL), in order to determine potential contaminants in the groundwater at the SRI site

(Table 4-16).

4.3.1 Overburden Groundwater A total of 22 overburden monitoring wells were sampled as part of the Phase I RI groundwater

investigation at the SRI site. Twenty-eight overburden wells were sampled as part of the Phase

II groundwater investigation. Tables 4-17 to 4-20 present the results of the analyses for the

overburden groundwater samples. Figure 4-3 and 4-4 present the organic and inorganic detected

concentrations in the monitor wells adjacent to the disposal cell.

Volatile Organic Compounds. Six overburden wells sampled during Phase I, and 14

overburden wells sampled during Phase Il, exhibited volatile organic concentrations above

detection limits (Table 4-17). Seventeen chlorinated volatile organic compounds were detected

in the overburden groundwater samples collected as part of the RI Phase I and II investigations.

The most predominant chlorinated volatile organic compounds detected in the overburden

groundwater samples were 1,1,l-TCA (detected in 10 wells in concentrations ranging from 0.1

µg/L to 160 µg/L), 1,1-DCA (detected in 11 wells in concentrations ranging from 0.4 µg/L to

1,300 µg/L), cis-1,2-DCE (detected in 8 wells in concentrations ranging from 0.05 µg/L to

160 µg/L), and chloroethane (detected in 7 wells in concentrations ranging from 0.3 µg/L to 390

µg/L). In addition, vinyl chloride was detected in two wells; DM-8S at a concentration of 120

µg/L and B-3W at a maximum concentration of 52 µg/L. Vinyl chloride and chloroethane are

the final degradation products of 1,1,1-trichloroethane ( 1, 1, 1-TCA), 1, 1-dichloroethane ( 1, 1-

DCA), and cis-1,2-dichloroethylene (cis-1,2-DCE). The remaining chlorinated volatile organic

compounds were detected infrequently and at low concentrations (<5 µg/L).

The wells exhibiting the highest total volatile organic concentrations were located in the

immediate vicinity of the fonner disposal cell area The highest total volatile organic

concentrations were present in wells MW-OSI (2,100,000 µg/L- acetone only), MW-05S (200,000

µg/L), B-3W (260 µg/L), DM-8S (350 µg/L), DM-80 (440 µg/L - acetone only), and MW-071

(220 µg/L). The highest voe concentrations were consistently observed in the samples collected

during the second round of groundwater sampling. This may be due in part to seasonal variations

such as lower water levels which would contribute to a lower contaminant dilution effect.

Comparatively, all other overburden wells which exhibited detected volatile organics displayed

total voe concentrations ranging from 0.1 µg/L to 3.2 µg/L.

The high concentration of acetone detected in well MW-051 has substantially elevated the

detection limit to 10,000 µg/L and interfered with the detection of other voes. This well was

installed on the outer fringe of the former disposal cell and may have been screened in direct

contact with the cell's leachate. In general, the shallow wells were screened in the flu vial sand

unit and the intermediate wells were screened in the till unit.

Of the 17 detected chlorinated volatile organic compounds, only 1,1,l-TCA, 1,1-DCA, cis-1,2-

DCE, methylene chloride, chloroethane, and vinyl chloride exceeded their respective NYSDEC

A WQ standards (NYSDEC, 1993). The elevated levels of one or more of the above mentioned

VOCs were limited to the following wells: B-3W, DM-8S, MW-05S and MW-08S. All of

which are located east (downgradient) of the former disposal cell area. Vinyl chloride and 1,2-

DCE were chosen to represent the chlorinated organic plume since these compounds are the

major constituents affecting the carcinogenic risks of the future use scenario evaluated in the

baseline risk assessment (Section 6.1 ).

Eight nonchlorinated volatile organic compounds were detected in the overburden groundwater

samples, the most predominant of which were acetone (detected in 7 wells in concentrations

ranging from 220 µg/L to 2,100,000 µg/L) and 2-butanone (detected in 3 wells in concentrations

ranging from 8 µg/L to 4,700 µg/L). In addition, relatively low levels of the constituents of

gasoline (i.e., BTEX) were detected in wells B-3W, DM-8S, DM-80, MW-05S and MW-08S in

concentrations ranging from 0.4 µg/L to 66 µg/L.

Of the detected nonchlorinated voes, acetone, 2-butanone, benzene, toluene, and ethylbenzene

concentrations exceeded their respective NYSDEC AWQ standards (see Table 4-16). These

elevated levels occurred in wells M-3W, DM-8S, MW-05S, MW-05!, MW-07S, MW-071, and

MW-08S, only. Acetone was chosen to represent the nonchlorinated organic plume since acetone

is the major constituent affecting the noncarcinogenic risks of the future use scenario evaluated

in the baseline risk assessment (Section 6.1).

No voes were detected in upgradient wells MW-06S and MW-061, located north of the former

disposal cell area.

Each of the Voes detected in the overburden groundwater in the vicinity of the former disposal

cell area were also detected in subsurface soil samples collected from this area. It is apparent

that the former disposal cell is leaching voe contamination into the groundwater immediately

downgradient (ic., east) of the former disposal cell.

Semlvolatlle Organic Compounds. A total of five semivolatile organic compounds were

detected in the groundwater samples collected from four separate on-site overburden monitoring

wells (Table 4-18). The monitoring wells which exhibited detected concentrations of semivolatile

compounds were B-3W, located approximately 70 feet east of the former disposal cell area,

MW-08S, located approximately 100 feet east of the former disposal cell area, B-8W, and MW

OlS, located west of the gravel pit. The semivolatile compounds detected were bis(2

µg/L], and B-3W [Phase Il at 0.7 µg/L]), di-n-octyl phthalate (detected in well MW-OlS [Phase

I at 10 µg/L]) and naphthalene (detected in wells MW-08S [Phase II at 2 µg/L] and B-3W

[Phases I and II, at 1 µg/L and 0.8 µg/L, respectively]). In addition, 4-methylphenol and 2,4-

dimethylphenol were detected in well B-3W at 18 µg/L and 2 µg/L, respectively.

None of the semivolatile organic compounds detected exceeded their respective NYSDEC A WQ

standards. Bis(2-ethylhexyl)phthalate concentrations exceeded the federal SDW A MCL in one

of three samples it was detected.

Pesticides and PCBs. A total of four pesticides were detected in low concentrations (<0.1

µg/L) in the overburden groundwater samples collected from four isolated monitoring wells

located within the SRI property (fable 4-19). These pesticides were beta-BHC (also known as

hexachlorocyclohexane), detected in monitoring well MW-OlS at 0.008 µg/L, endrin ketone,

detected in well MW-05S at 0.014 µg/L, and heptachlor epoxide, detected in well MW-061 at

0.061 µg/L. Of the three pesticides detected, only heptachlor epoxide and beta-BHC have

applicable NYSDEC A WQ standards ("non-detect"). In addition, heptachlor epoxide has a

SDW A MCL (0.0002 µg/L).

The hand-dug well (HD-01), located in the western portion of the site, exhibited a pesticide

concentration above the detection limit. The pesticide dieldrin was detected at location HD-01

during Phase I sampling at a concentration of 0.0024 µg/L. This concentration exceeded the

NYSDEC A WQ standard of "non-detect" for this compound.

No PCBs were detected in the overburden groundwater samples.

Inorganic Analytes. Eight inorganic analytes were detected in elevated concentrations above

NYSDEC A WQ standards and/or SDWA MCLs in the overburden groundwater samples

(Table 4-20). These constituents were iron (elevated in 22 wells), magnesium (elevated in 18

wells), manganese (elevated in 8 wells in concentrations ranging from 321.3 µg/L to 2066 µg/L),

sodium (elevated in 5 wells), arsenic (elevated in 4 wells in concentrations ranging from 80.6

µg/L to 95.3 µg/L), lead (l well [B-8W] at a concentration of 25.5 µg/L), and chromium (l well

[DM-01] at a concentration of 235.1 pg/L). In addition, nickel (which does not have an available

NYSDEC AWQ standard) exceeded the EPA SDWA MCL of 100 µg/L in well DM-01, at a

concentration of 225.6 µg/L. Lead concentrations exceeded the more stringent SDW A MCL of

15 µg/L in hand-dug well HD-01 at 16.3 µg/L.

Based on a comparison of background well MW-010 data, only 6 wells exceeded background

concentrations for manganese and only 13 wells exceeded the background concentration for iron.

The remaining elevated analyte occurrences remained unchanged.

The overburden monitoring wells which exhibited the most elevated analytes (i.e., 5) were wells

B-3W, OM-8S, and MW-08S, all of which are located immediately east of the former disposal

cell area. In addition, well B-8W, located in the southern portion of landspreading area L, also

exhibited five inorganic analytes elevated above NYSOEC A WQS standards.

In general, the filtered samples exhibited lower concentrations than those seen in the unfiltered

samples. For example, manganese was detected in well B-8W at 809.3 µg/L in the unfiltered

sample and 11.5 µg/L in the filtered sample (Appendix A). This may indicate that the majority

of the inorganic constituents are present in the less mobile, suspended particulate phase within

the overburden groundwater samples collected at the SRI site, and may not be mobile in the

subsurface flow system.

Summary. The majority of the contamination present in the overburden groundwater appears

to be isolated in the area east of the former disposal cell; in particular, in the vicinity of wells

B-3W, OM-8S, OM-80, MW-05S, MW-051 and MW-08S. The most predominant contaminants

present in the overburden groundwater in the vicinity of the former disposal cell area are voes

(both chlorinated and nonchlorinated) and inorganic analytes, mainly arsenic and manganese.

Since the overburden well located furthest east (downgradient) of the former disposal cell area

(i.e., MW-08S) is contaminated, primarily with VOCs and inorganics, it is not possible to fully

delineate the full areal extent of contamination. It is very likely that the contamination extends

into the wetlands located immediately east of this area. The former disposal cell appears to be

the only significant source of overburden groundwater contamination at the SRI site. It is evident

that the leachate from the former disposal cell has migrated in an easterly direction with the local

flow of overburden groundwater in this area.

4.3.2 Bedrock Groundwater A total of five on-site bedrock monitoring wells were sampled as part of the Phase I RI

groundwater investigations at the SRI site. Eight bedrock monitoring wells were sampled during

the Phase II sampling round. Tables 4-21 to 4-23 present the summary of analytical results for

the bedrock groundwater samples.


SLR-0010532

Volatile Organic Compounds. Four bedrock wells exhibited positive detections

concentrations of volatile organic compounds (Table 4-21). The only well to show total volatile

organic concentrations above 1 µg/L was MW-07D, located approximately 150 feet east of the

former disposal cell area, at 280 µg/L (acetone). Other detected low concentrations detected in

MW-07D was 1,1-dichloroethane (0.4 µg/l) and 2-butanone (10 pg/I). 2-Butanone was detected

in MW-05D at concentrations of 1 µg/l. Some VOC contamination present in the overburden

groundwater in the eastern vicinity of the former disposal cell area has migrated vertically into

the bedrock aquifer in this area; however, the bedrock aquifer contains significantly lower

concentrations than those seen in the adjacent overburden wells.

Upgrad.ient bedrock well MW-09D, located west of the former disposal cell, exhibited low

concentrations of chloroform (0.1 µg/L) and toluene (0.3 µg/L). MW-040 exhibited low

concentrations of chloroform (0.1 µg/l) and toluene (0.3 µg/l). Similar to the overburden well

sampling, the highest VOC concentrations were detected during the Phase II sampling.

Only acetone concentrations in the bedrock groundwater samples exceeded the NYSOEC A WQ

standard. The elevated level (280 µg/L) was detected in well MW-070 only.

Semlvolatlle Organic Compounds. No semivolatile organic compounds were detected in

the samples collected from the on-site bedrock wells.

Pesticides and PCBs. Only well MW-OlD, located west of the gravel pit, exhibited a

pesticide concentration above the detection limit in the bedrock groundwater (Table 4-22). The

pesticide aldrin was detected in well MW-OlD, during Phase I sampling, at a concentration of

0.011 µg/L. This concentration exceeded the NYSDEC AWQ standard of "non-detect" for this

compound.

No PCBs were detected in the bedrock groundwater samples.

lnorgank Analytes. Only two inorganic analyte concentrations detected in the bedrock

groundwater samples exceeded the NYSDEC AWQ standards (Table 4-23). These constituents

were cadmium (detected in well MW-OlD) and manganese (detected in well MW-020). The

highest concentrations of these two constituents were present in the unfiltered samples.

In addition, an estimated concentration of 7 µg/L for cadmium was detected in well MW-010

during the second round of sampling. This concentration exceeds the SOW A MCL of 5 µg/L

for cadmium. The concentration of 73.5 µg/l for manganese in MW-02 exceeded the SOWA

MCL.

Summary. The most significant contamination present in the bedrock groundwater is localized

in the area east of the former disposal cell; in particular in the vicinity of well MW-07D. The

main form of contamination is voes, especially acetone. It is likely that the contamination

present in the overburden wells in this area has migrated from the fluvial sands into the dolomite

bedrock. Once into the highly fractured bedrock aquifer, the contamination would likely migrate

with the flow of groundwater in a east-northeasterly direction, and possibly off the SRI property.

4.3.3 Residential Wells

A total of 17 off-site private residential wells were sampled as part of the Phase I groundwater

investigation and a total of 23 residential wells were sampled as part of the Phase IT RI

groundwater investigation at the SRI site. Most of these wells are installed in the local bedrock

aquifer. Tables 4-24, 26, and 28 present the analytical results of the Phase I and Phase Il RI

residential well groundwater samples. The NYSOOH collected additional residental well samples

on November 5, 1992 and August 9-10, September 9, September 30, and October 20-21, 1993.

Tables 4-25, 27, and 29 present the analytical results of the NYSDOH residential well sampling

program. Figure 4-5 presents organic and inorganic detected concentrations in the residential

wells.

Volatile Organic Compounds. During the RI, five residential wells showed low levels of

volatile organic compounds ranging from 0.03 µg/L to 1.0 µg/L (Table 4-24). Four of these

wells (i.e., HW-01, HW-02, HW-06, and HW-08) are located generally northeast of the southern

portion of the SRI property. Well HW-06 exhibited the most detections of volatile organic

compounds (i.e., 4); tetrachloroethene (0.6 µg/L), trichloroethene (0.1 µg/L), 1,4-dichlorobenzene

(0.2 µg/L), and cis-1,2-dichloroethylene (0.08 µg/L). Well HW-08, located approximately 250

feet south of well HW-06, exhibited a single detection of trichloroethene (0.03 µg/L).

The remaining three residential wells only exhibited low detections (i.e., 0.8 µg/L - 1 µg/L) of

methylene chloride, a common laboratory contaminant, in the Phase I sampling only. Methylene

chloride was not detected in the former disposal cell leachate sample.

None of the detected voe concentrations exceeded their respective NYSDEC A WQ standard

(NYSDEC, 1993).

In the NYSDOH residential well samples, only 1 TCL compound, 1,1,1-trichloroethane, was

detected at 2.1 µg/L at HW-20 (Table 4-25).

Semivolatile Organic Compounds. A total of four semivolatile organic compounds wereidentified in the groundwater samples collected from residential wells (Table 4-26). The mostfrequently detected semivolatiles were bis(2-ethylhexyl)phthalate (15 wells ranging from 0.4 pg/Lto 68 pg/L) and di-n-butyl phthalate (9 wells ranging from 0.4 pg/L to 0.8 pg/L). Both of thesecompounds are common laboratory contaminants. In addition, di-n-octyl phthalate was detectedin one sample location (HW-20 [Phase n only] at 1.0 pg/L) and diethyl phthalate was detectedin one sample (HW-05 [Phase I only] at 1 pg/L).

The only semivolatile compound to exceed NYSDEC AWQ standards was bis(2-ethylhexyl)phthalate, which was exceeded in two residential wells. These two wells were HW-4, locatednorth of the SRI property boundary at a concentration of 18 pg/L, and HW-05, located east ofthe SRI property boundary at a concentration of 65 ug/L. Both of these elevated concentrationswere identified during the Phase I sampling program only. The second round of sampling ofthese two residences revealed no detected concentrations of bis(2-ethylhexyl)phthalate.

It should be noted that phthalates are common constituents of plastics. Polyethylene plastichosing is normally connected to the submersible pumps used in private residential wells. Theplastic tubing may contribute low level phthalates to the drinking water.

All detected SVOCs in NYSDOH residential well samples were well below NYSDEC and federalMCLs with the exception of hexachloroetnane which was detected at 9 pg/L at HW-5 (Table4-27). The NYSDEC MCL for hexachloroethane is 5 pg/L. Four odier SVOCs were detectedat HW-5 including phenol (0.8 pg/L), 2-chlorophenol (0.3 pg/L), bis(2-ethylhexyl)phthalate (0.2pg/L), and di-n-butyl phthalate (0.07 pg/L). Nine SVOCs were detected at HW-12 includingpyrene (0.2 pg/L), butyl benzyl phthalate (0.1 pg/L), di-n-octyl phthalate (0.07 pg/L), chrysene(0.2 pg/L), fluorene (0.03 pg/L), phenanthrene (0.1 pg/L), anthracene (0.09 pg/L), andfluoranthene (0.1 pg/L). Pyrene, butyl benzyl phthalate, and di-n-octyl phthalate were alsodetected at HW-14 at concentrations of 0.1 pg/L, 0.08 pg/L, and 0.05 pg/L, respectively. SixSVOCs were detected at HW-13 including phenol (0.3 pg/L), bis(2-ethylhexyl)phthalate (0.2pg/L), 2-chlorophenol (0.1 pg/L), and 2-methylnaphthalene (0.02 pg/L). Dimethylphthalate wasdetected at 0.2 pg/L and 0.1 pg/L at HW-2 and HW-3, respectively.

Pesticides and PCBs. Three pesticides were detected in groundwater samples collected fromthree separate residential wells (Table 4-28). The pesticides detected were dieldrin (in wellHW-10, located north of the SRI property boundary, at 0.002 pg/L), 4,4'-DDE (in well HW-13,located north of the SRI property boundary, at 0.0027 pg/L), and methoxychlor (in well HW-14,located northwest of the SRI property boundary, at 0.043 pg/L).

dieldrin and 4,4'-DDE exceeded their respective NYSDEC AWQ standards of "non-detect."

The PCS aroclor-1248 was detected in well HW-14 at a concentration of 0.4 pg/L. Thisconcentration exceeded the NYSDEC AWQ standard for PCBs of 0.1 pg/L. Aroclor-1248 wasnot detected in any media samples collected from the SRI site.

No pesticides or PCBs were detected in NYSDOH residential well samples (Table 4-29).

Inorganic Analytes. Four inorganic analytes were detected in elevated concentrations abovetheir respective NYSDEC AWQ standards (Table 4-30). These constituents were magnesium(elevated in 15 wells), iron (elevated in 11 wells), sodium (elevated in 3 wells), and arsenic(elevated in well HW-07 only, at a concentration of 37.2 pg/L). In addition, lead concentrationsexceeded the EPA action level of 15 pg/L in well HW-07 (16.8 pg/L) during Phase I samplingonly. It was not detected in this homeowner well during Phase n sampling. Manganeseconcentrations exceeded the secondary MCL in well HW-07 (Phase I and II), HW-20 (Phase H),HW-02 (Phase H), HW-14 (Phase I and U) and HW-3 (Phase I only). The unffltered samplesexhibited higher concentrations of the above mentioned inorganics than did the filtered samples.

In the NYSDOH samples, lead was detected above the EPA action level for lead of 15 pg/L atHW-11 (170 pg/L), HW-7 (15 pg/1) and at HW-13 (78 pg/L) (Table 4-31). Arsenic was detectedabove the NYSDEC MCL of 25 pjj/L at HW_-JJ$J pg/L). Iron was detected at concentrationsexceeding the EPA secondary MCL of 300 pg/L at HW-7, HW-9, HW-10, HW-11, HW-12, andHW-13. Manganese was detected at concentrations exceeding of the EPA secondary MCL (300pg/L) at HW-14 (2,360 pg/f). Copper was detected at concentrations above the NYSDEC MCLof 200 pg/1 at HW-13 (577 pg/1). Zinc was detected at concentrations above the NYSDEC MCLof 300 pg/1 at HW-11 (1,220 pg/1). Manganese ws detected above the NYSDEC MCL of 300pg/1 at HW-14 (2360 pg/1).

Summary. Low concentrations of volatile organic, semivolatile organic, and pesticidecompounds were detected in a limited number of residential wells; in particular, those locatedeast of the SRI property boundary. The only inorganic constituent of significance was arsenic,which was detected in well HW-07, located immediately east of the SRI property boundary.All of the contaminants detected in the residential well samples were also detected in the on-siteSRI overburden monitoring wells, with the exception of aroclor-1248.

4.4 Surface Water and SedimentThis section describes the nature and extent of contamination in the surface water and sedimentat the SRI site. Section 2.4 discussed the surface water and sediment sampling techniques andmethodologies in detail. A total of 18 locations were sampled for both surface water and

Both filtered and unfiltered surface water samples were collected for inorganic analyses. Themain areas of focus of the surface water and sediment investigation were portions of the easternwetlands adjacent to the landspreading areas and former disposal cell area (12 samples: WE-05through WE-16), with additional samples collected from the northwestern wetlands area sedimentas pan of this Rl. Figure 2-2 presents the surface water and sediment sample locations. Bothfiltered and unfiltered surface water samples were collected for inorganic analyses. The mainareas of focus of the surface water and sediment investigation were portions of the easternwetlands adjacent to the landspreading areas and former disposal cell area (12 samples: WE-05through WE-16), with additional samples collected from the northwestern wetlands area (2samples: WN-17 and WN-18). In addition, 4 samples (TS-01 through TS-04) were collectedfrom locations along the eastern tributary to Sucker Brook which conveys water away from thesite.

4.4.1 Surface Water AnalysesThe surface water samples collected as part of this RI were analyzed for full TCL/TALparameters, including volatile organic, semrvolatflc organic, pesticide, PCB, and inorganicanalytes (including cyanide). Tables 4-32 through 4-35 as well as Figure 4-6 present thesummary of compounds detected in the surface water samples. Appendix A presents the fullsurface water laboratory analytical results.

In order to assess the potential environmental concern of each of the constituents detected in thesurface water samples collected from the SRI site, the NYSDEC "Ambient Water QualityStandards and Guidance Values, October, 1993" was referenced to determine the allowablesurface water concentrations for "Class D" bodies of water, assuming an average hardness valueof 300 ppm. The hardness value of 300 ppm is the arithmetic mean of the analytical results ofsurface water samples collected during this RI. The closest New York State classifiable bodyof water to the SRI site is Sucker Brook, which is designated as Class D (i.e., protection for fishsurvival or wildlife consumption of fish). Also, the EPA Water Quality Standards were referredto when the constituent didn't have an available NYSDEC AWQS standard or the EPA standardwas lower than the NYSDEC AWQ standards (Federal Register, 1992).

Volatile Organic Compounds. Seven volatile organic compounds were detected at very lowconcentrations (near or slightly above the detection limits) in 6 of 18 surface water samplescollected as part of this RI. Table 4-32 presents the results of the VOC analyses for the surfacewater samples.

The samples which exhibited the highest volatile organic concentrations were WN-17 (acetone -12 pg/L) and WN-18 (toluene - 6 pg/L), both located in die area of the northwestern wetlands.

The remaining samples had total VOC concentrations ranging between 0.2 ug/L to 0.8 pg/L.No VOCs detected in the surface water samples exceeded NYSDEC AWQ standards.

Semivolatile Organic Compounds. A total of five different semivolatfle organic compoundswere detected at low concentrations (<5 pg/L) in the surface water samples collected as pan ofthis RI (Table 4-33). Only 6 of 18 surface water samples exhibited detections of at least one ofthese compounds. The sample with the highest total semivolatile organic concentration was WN-18 (4-methylphenol - 2 pg/L and di-n-butyl phthalate - 1 pg/L), located in the area of thenorthwestern wetlands. In addition, sample WE-15, located directly east of the former disposalcell, exhibited a detection of 4-chloro-3-methylphenol (2 pg/L) and sample TS-02 showed adetection of pentachlorophenol (2 pg/L). N-nitrosodiphenylamine was detected in sample WE-05,WE-06, and WE-09 at a concentration of T^pg/1.

No semivolatile organic compounds detected in the surface water sarapfes exceedea"NYSDECAWQ standards.

PestlCld0S and PCBs. Four pesticides were detected at low concentrations (<0.01 pg/L) inthe surface water samples collected at the SRI site (Table 4-34). These constituents are endrin,endosulfan sulfate, and gamma-BHC (also referred to as lindane). Only 4 of 18 surface watersamples exhibited detections of one of these constituents. Endrin was detected in samples TS-01(0.0028 pg/L) and TS-02 (0.0021 pg/L), both of which are located at the eastern tributary toSucker Brook. Both samples slightly exceeded the NYSDEC AWQ standard for endrin of 0.002pg/L. Gamma-BHC was detected only in sample WE-09, located east and topographicallydowngradient of landspreading area L, at an estimated concentration of 0.0026 pg/L. Endosulfansulfate was detected in sample WN-17, located in the northwestern wetlands, at 0.0053 pg/L.There are no NYSDEC AWQ standards for gamma-BttC and endosulfan sulfate. No pesticideexceeded their respective EPA Water Quality Standards.

EDIS/ENG/ay071494jp4 4-162 SLR-0010587

PCBs were not detected in any of the surface water samples collected.

Inorganic Analytes. Eighteen inorganic constituents were detected in the surface watersamples collected from the SRI site (Table 4-35). In general, the filtered samples exhibited lowerconcentrations than the unfiltered samples indicating that the majority of the inorganicconstituents detected in the surface water were present suspended-phase particulates.

The only inorganic constituent to exceed die NYSDEC AWQ standard was iron. The standardfor iron is 300 ug/L. The concentrations of iron in the surface water samples ranged from202.5 pg/L to 37,176 ug/L for unfiltered samples and 136 ug/L to 3071 pg/L for filteredsamples. The sample which exhibited the highest iron concentration (unfiltered) was from asample collected from location TS-02, which is located at the eastern tributary to Sucker Brook.In addition, copper exceeded the EPA Water Quality Standard of 18 pg/L in sample TS-04 at45.2 pg/L and cadmium exceeded its EPA Water Quality Standard of 3.9 pg/L in sample WE-12at 12.2 pg/L.

Surface Water Summary. Surface water organic contamination at the SRI site is minimal.Low concentrations of a few volatile and semivolatile organic compounds and pesticides weredetected, primarily in the area of the northwestern wetlands and the eastern tributary to SuckerBrook. The only inorganic constituent to exceed the NY State Ambient Water Quality Standardsfor Qass D waters was iron, which was detected in concentrations as high as 37,176 pg/L in thesuspended-phase in the eastern tributary to Sucker Brook. Copper and cadmium concentrationsexceeded EPA Water Quality Standards in surface water samples TS-04 (45.2 pg/L) and WE-12(6.3 pg/L), respectively.

4.43 Sediment AnalysesSediment samples were collected coincidentally with the surface water samples at the same18 sample location points (Figure 2-2). The sediment samples were analyzed for full TCL/TALparameters, including cyanide. Tables 4-36 through 4-39 as well as Figure 4-7 present thesummary of compounds detected in the sediment samples. Appendix A presents the sedimentlaboratory analytical results.

Volatile Organic Compounds. Three volatile organic compounds were detected in 4 of 18sediment samples collected as part of this RI (Table 4-36). These compounds are chloroform,2-butanone and toluene. All three compounds were detected in sample WE-13, located east ofthe former disposal cell, at 1 pg/kg, 17 pg/kg and 6 pgAg, respectively. Other sediment samples

to exhibit detected concentrations of volatile organic compounds were WE-12 (chloroform - 1pg/kg) and WE-14 (chloroform - 2 pg/kg), both of which are located east of the former disposalcell, as well. Sample WN-18, collected from the northwestern wetlands, exhibited a detectionof 2-butanone (12 pg/L).

Setntvolatile Organic Compounds. Five semivolatile organic compounds were detected inthe sediment samples collected as part of this RI (Table 4-37). These compounds are di-n-butylphthalate, phenol, 4-methylphenol, 4-chloro-3-methylphenol, and 2,4-dimethylphenol. Five of18 samples exhibited a detection of at least one of these compounds. The sample whichexhibited the highest concentration of total semivolatile organics was WE-05, located in theeastern wetlands downgradient of landspreading area M (phenol, 75 pg/kg; 4-methylphenol, 43pg/kg; and 4-chloro-3-methylphenol, 210 pg/kg). The only other sample to show a significantsemivolatile concentration was WE-13, located east and directly downgradient of overland flowfrom the former disposal cell area (2,4-dimethylphenol - 110 pg/kg). The three remainingsamples, TS-01, TS-04, and WE-06, only had detected concentrations of di-n-butyl phthalate at43 pg/kg, 58 pg/kg, and 43 pg/kg, respectively.

Pesticides and PCBs. Five pesticides were detected in the sediment samples collected at theSRI site as part of this RI (Table 4-38). These constituents are heptachlor epoxide,methoxychlor, endrin aldehyde, aldrin, and 4,4'-DDE. Twelve of 18 sediment samples exhibiteddetections of at least one of these constituents. •"

The highest pesticide concentration was detected in sample location TS-02 (methoxychlor -6.3 pg/L). In addition, sample locations WE-06 (methoxychlor - 3.6 pg/kg, endrin aldehyde -0.44 pg/kg), WE-05 (methoxychlor - 2.8 pg/kg), and WE-07 (methoxychlor - 2.3 pg/kg andendrin aldehyde - 0.49 pg/kg) exhibited pesticide detections. All three of these samples werecollected southeast and topographically downgradient of landspreading area M.

The remaining samples which had detections of pesticides exhibited concentrations below2 pg/kg.

There were no detections of PCBs in the sediment samples collected as part of this RI.

Inorganic AnalytOS. Twenty inorganic analytes were detected in the sediment samples (Table4-39). There are no true representative site background (upstream) sediment data available forcomparison. Therefore, in order to determine if any of the analytes detected are at concentrationsof potential concern, the NYSDEC Technical Administrative Guidance Memorandum (TAGM)

EDIS/ENG/ay071494jp4 4-171SLR-0010596

"Determination of Soil Cleanup Objectives and Cleanup Levels," January 24, 1994 (NYSDBC,1994) and the NYSDEC Sediment Criteria Methodology were used as a preliminary screeningtool.

Based on this comparison, 7 analytes exhibited detected concentrations which exceeded theirrespective NYSDEC "soil cleanup objective levels" listed in the above mentioned guidancedocument These constituents are arsenic (7 samples), cadmium (2 samples), chromium(1 sample), iron (18 samples), manganese (8 samples), and mercury (11 samples).

The sample locations which exhibited the greatest number of elevated analytes (i.e., 5) wereTS-03, located near the eastern tributary to Sucker Brook, and WE-12, located in the easternwetlands, east of the former disposal cell area. In general, the sample locations which weresituated downgradient of overland flow from the former disposal cell area (i.e., WE-11 throughWE-16 and TS-03 and TS-04) exhibited the highest number of elevated analytes. In particular,the analytes which were most consistently elevated in the samples collected from these locationswere arsenic (4200 pg/kg - 23,900 pg/kg), selenium (5200 pg/kg - 8100 pg/kg), mercury(200 pg/kg - 800 pg/kg), and iron (6,917,600 pgAg - 85,760,000 pg/kg). Conversely, thesamples collected from the northwest wetlands exhibited the lowest number of elevated analytes.

Cyanide, which does not have an available NYSDEC "soil cleanup level objective," was detectedin WN-18 (2,900 pg/kg), located in the northwestern wetlands.

Sediment Summary. Similar to the surface water data, only low concentrations of a fewvolatile and semivolatfle organic compounds and pesticides were detected in the sedimentsamples. The majority of the volatile and semivolatile organic compounds were detected in thearea east of the former disposal cell area. The pesticides were primarily detected in the area ofthe eastern wetlands, southeast of landspreading area M. The highest number of elevatedinorganic analytes were detected in samples collected east and downgradient of overland flowfrom the former disposal cell area.

5.0 Environmental Fate and Transport

Knowledge of the environmental fate and transport of the constituents present at the SRI site wasused to determine the potential for migration of the constituents of concern and to assess thepotential for exposure to these constituents. Two major factors affecting the fate and transportof a chemical are its chemical mobility and its persistence in environmental media. Mobility isa measure of the tendency for a chemical to migrate through the environment and is affected bysite characteristics and by the physical/chemical characteristics of the compound. The chemical-specific characteristics are: chemical aqueous solubility, volatilization, sorption, hydrolysis,photolysis, and oxidation rates. Persistence, a measure of the time a chemical remains in theenvironment, is influenced by many of the factors affecting chemical mobility, such as photolysis,hydrolysis, and oxidation. Persistence is also a function of chemical-biological interactions inthe environment such as biodegradation and/or bioaccumulation.

Presented in this chapter is a summary of the environmental fate and transport processes of thechemicals of potential concern at the site. Section 5.1 describes the potential routes of migrationfrom the site. Section 5.2 describes the fate and transport processes that affect the constituentsfound on the site. Section 5.3 discusses contaminant migration; particularly in the groundwaterflow regime.

5.1 Potential Routes of MigrationContaminants can be transported from their source(s) to other areas as a result of several potentialmigration pathways. Potential migration pathways for transport of contamination from the SRIsite include transport by surface water and groundwater. These contaminant transport pathwaysprovide a potential link between known sources and potential receptors.

The transport of contaminants away from source areas is dependent on several factors. Theseinclude site characteristics such as geology (including soil and bedrock conditions); hydrology(including groundwater and surface water conditions); climatology (including precipitationconditions); and contaminant characteristics such as physical/chemical properties, chemicalconcentration, and chemical distribution. Physical characteristics of the SRI site study area arepresented in Chapter 3.0 (Physical Characteristics of the Study Area). Chemical distributions andconcentrations are presented in Chapter 4.0 (Nature and Extent of Contamination). Fate andTransport Properties and Site-Specific Contamination Migration are presented in Sections 5.2 and5.3, respectively, of this chapter.

EDIS/ENG/ay071494.rpt 5-1SLR-0010599

For the SRI site, the potential migration pathways of contaminants from the source areas include:

• Vapors and airborne particulates transported via air currents• Percolation through native soils to groundwater• Groundwater transport• Groundwater recharges to surface water• Surface water runoff• Foodchain bioaccumulation.

5.1.1 Airborne ContaminantsSince the surficial soil (0-2 feet deep) does not contain significant levels of contaminants, organicvapors and contaminated dust particulates are not likely to be transported off-site. Furthermore,the fields on the SRI site are heavily vegetated with grasses, reducing the potential for migrationof dust particulates. This exposure pathway was not considered significant for the SRI site andit was not evaluated in detail.

5.13 Percolation Through Native Soils to GroundwaterThe primary routes of contaminant migration from surface and subsurface soils are leaching intogroundwater. Volatile organics present at the SRI site adjacent to the northeastern corner of theformer disposal pell at a depth of approximately 18-24 feet deep have migrated into groundwaterby the percolation of rainwater (or snow melt). The original contents of the former disposal cellleached into groundwater and migrated through percolation through native soils to the overburdengroundwater. However, since the former disposal cell's remediation in 1990, the significantcontamination remaining adjacent to the northeastern section of the former disposal cell area iscontained in the saturated zone.

5.1.3 Groundwater TransportOnce a soluble-phase substance is in groundwater, it is transported in the direction ofgroundwater flow. The hydrogeology in the immediate vicinity of the SRI site is discussed inSection 3.8 (Hydrogeology). The predicted overburden groundwater flow direction at the sitewest of the ridge is toward the north and west and to the east of the ridge groundwater flows inan east-southeast direction. The predicted bedrock groundwater flow is in an east-northeasterlydirection. Should soluble chemical constituents enter the groundwater they would flow in thedirection of groundwater movement. The rate of transport of these chemical constituents in theoverburden zone of the aquifer is determined, in part, by equilibrium partitioning between themobile aqueous phase and the stationary soil particles. The degree of partitioning is governedby the organic matter content of the soils.

EDIS/ENG/ay0714M.rpt 5_2SLR-0010600

Release and transport to groundwatei is the primary route and mechanism of on-site contaminantmigration for both dissolved inorganic and organic compounds detected at the SRI site. Tocharacterize this important migration pathway, groundwater flow direction, velocity andtransmissivity were calculated during both phases of the RI. The high transmissivity of thebedrock unit facilitates the transport of dissolved contaminants via groundwater movement.Additional information on the hydrogeology, aquifer conditions, and groundwater flow directioncan be found in Section 3.8.

5.1.4 Groundwater Recharge to Surface Water StreamsThe eastern tributary to Sucker Brook is located within the site boundary. Sucker Brook isdesignated a Class D water body by the State of New York (i.e., protection for fish survival).Sucker Brook flows north, ultimately entering the St. Lawrence River near Waddington, NewYork. The headwaters to the tributary are formed by low lying wetlands located in the easternportion of the site. These waters are considered perennial and intermittent. The results of thePhase I and Phase n investigation have determined that the overburden as well as the bedrockaquifers are hydraulically connected to the surface water present in the wetlands. However, dueto such seasonal variations in the groundwater table and the intermittent nature of the stream, thesurface water can be an expression of groundwater discharge during wet periods with a highgroundwater table or the surface water runoff can recharge the overburden aquifer during dryperiods. The overburden groundwater recharge or discharge condition is highly dependent on theseasonal fluctuation of the water table.

5.7.5 Surface Water RunoffSurface water runoff at the SRI site flows in two directions; easterly and westerly. Surface waterrunoff from the easternmost landspreading areas and the former disposal cell area drains into theeastern wetlands. An arcuate cutoff ditch constructed along the central-eastern edge of the siteseparates the landspreading areas from the wetland, however, a break in the cut-off ditch (nearMonitoring Well B-8W) allows water in the ditch to enter the wetland.

Runoff to the west of the SRI topographic divide generally flows unimpeded into thenorthwestern wetlands. The on-site gravel pit likely intercepts some flow to the west. A smallintermittent stream flows from the northwestern wetlands to an area of standing water on thenorth side of Pray Road.

5.1.6 Foodchaln BloaccumulatlonMany organic and some inorganic constituents have a potential to bioconcentrate andbioaccumulate in the foodchain. Such contaminants can enter the foodchain through direct


bioconcentration from an aqueous media, root uptake from soils to plants, ingestion of water,incidental ingestion of soils and sediments, and ingestion of contaminated plants or animal preyas food sources. The ability to bioaccumulate through the foodchain is related to the persistenceof the constituent and the resistance to metabolic breakdown or removal.

5.2 Contaminant PersistenceThis section defines the factors affecting environmental persistence and mobility processes andsummarizes pertinent environmental fate and transport data for the chemical classes detected atthe SRI site. Environmental persistence parameters for organic chemicals detected at the facilityare presented in Table 5-1.

Based on site-specific characteristics of the SRI site, the most important persistence and mobilityprocess for organic constituents is likely to be aqueous solubility. The greater the solubility, thegreater the potential for migration via groundwater transport. Of the organics detected at thefacility, those with "high" solubilities (i.e., greater than 10,000 mg/f) are listed below(Verschueren, 1983):

• Acetone• 1,1-Dichloroethane

1,2-Dichloroethene• Vinyl chloride• Trichloroethene• Benzene• Methylene chloride

For inorganics, potential migration in groundwater is related to the constituents' distributioncoefficient (Kd) (Section 5.2.2.2). Of the inorganics detected at the site, those with the greatestpotential for migration (i.e., with Kd values less than 50) are presented below (Baes, et al., 1984):

• Cadmium• Mercury• Copper• Zinc• Antimony• Silver

Cobalt.

The fate and transport mechanisms discussed in detail below deal with the chemical and physicalreactions that take place in the environment and their effect on contaminant transport.

5.2.1 Factors Affecting Environmental Fate and Transport ProcessesAqueous solubility is the measure of a chemical's ability to dissolve in water and is expressedin units of chemical mass/unit volume of water (e.g., milligrams per liter (mg/{). Aqueoussolubility is an important determinant of chemical concentration and residence time in water.Highly soluble chemicals readily dissolve in water and remain in solution, whereas chemicalsexhibiting low solubility tend to adsorb to solids or form nonpolar phases. Solubility is alsorelated to the ease of teachability of the chemical from wastes and soils to water.

Volatilization describes the movement of a chemical from the surface of a liquid or solid matrixto a gas or vapor phase. Volatilization is calculated from the equilibrium vapor pressure whichmeasures chemical solubility in air (when the initial chemical concentration is in the liquidphase). Volatilization losses to air are related to die chemical concentration, molecular weight,solubility and ambient temperature. The vapor pressure, Henry's Law constant, and solubilityof a chemical all play an important role in surface water constituent transport. The tendency fora compound to volatilize from surface water can be predicted from the Henry's Law constantwhich relates equilibrium concentration of a chemical in the vapor phase to its concentration inthe dissolved phase. Volatilization is a particularly important environmental fate process forchemicals exhibiting low aqueous solubility and polarity. Lyman, et al. (1982), describedcompounds as readily, significantly, or limitedly volatilized, based on the values of their Henry'sLaw constants. These values (in atmosphere-cubic meters per mole [atm-m3/mol] are £ 10~3,10~3

to 10~5 and <10~5, respectively.

Readily volatilized organics detected at the SRI site include the following (from Table 5-1), listedin decreasing order of volatility:

• Acetone• Chloroethane• 1,1 -Dichloroethene• Vinyl chloride• 1,2-Dichloroethene• 1,1,1 -Trichloroethane• Tetrachloroethene

Adsorption and desorption are, respectively, the binding to, and release from, a chemical to asolid matrix. In general, the less polar the chemical of interest, the greater the adsorption to thesolid phase (e.g., soils, sediments and suspended solids). Adsorption to a solid phase limits thefraction available for other fate processes such as volatilization and/or hydrolysis. Partition


coefficients, which are important measures of sorptive characteristics, define the relativeconcentration of a given chemical in two phases or matrices.

Partition coefficients are expressed as concentration ratios between two phases. Partitioncoefficients useful in describing the environmental behavior of a chemical include Kow, Kj andK^. These factors are briefly discussed below:

The octanol-water partition coefficient is the ratio of the chemical concentration inoctanol to that in water at equilibrium conditions. Octanol serves as a surrogate forhighly nonpolar lipid or organic phases. The Kow is often used to estimate theextent to which a chemical will be expected to partition from water into lipidportions of organisms. Compounds with low KDW values have smallbioconcentration factors (BCF), small sediment/soil partition coefficients, andrelatively high water solubilities. A high Kow level is indicative of the chemical'spotential to partition into sediments or soils, a large BCF, and a low water solubility(Lyman et al., 1982).

The soil-water partition coefficient is the ratio of the chemical concentration in thesolid and aqueous phases. The Kj values are dependent upon the organic carboncontent of the solid phase for organic compounds.

The organic carbon partition coefficient of a chemical is one parameter that isindicative of its potential to adsorb to soil. High K^ values usually indicate a hightendency of an organic compound to adsorb to the soil organic matter. K^. valuesare calculated only for organic compounds since adsorption of inorganics to solidsis less dependent upon the organic carbon fraction of the solid phase.

Bioconcentration is the accumulation of a chemical by plants or animals usually due to anaqueous exposure. The potential for bioconcentration is quantified by BCFs, which are theconcentration ratios of the constituent in the animal or plant tissue and the environmental mediumconcentration. Organic chemicals with large BCFs (e.g., pesticides) generally are lipophilic andtend to accumulate in animal fat tissues. Some metals (e.g., mercury) can also bebioconcentrated. Bioaccumulation is the accumulation of a constituent both via the water andthrough food. Utilizing BCFs alone would tend to underestimate the potential concentration inthe organism if the food chain transfer contributes significantly to the exposure.

Biotransformation/Biodegradation: Many microorganisms and biota can metabolically transformxenobiotic compounds to products which may be more or less as toxic than the originalcompounds. Biotransformation includes a variety of enzyme-catalyzed reactions such asoxidation and reduction.

EDIS/ENG/ay0714M.rpt 5-9SLR-0010607

Hydrolysis is the reaction of a chemical with hydrogen ions (H+) and hydroxyl radicals (OH")resulting in the breakdown or structural modification of the chemical in the environment Theextent of a chemical's hydrolytic reactivity depends on both the pH of the environment and themolecular structure of the specific chemical.

Photolysis is a chemical decomposition process which is induced by radiant energy (sunlight).The rate of loss of a chemical from photochemical reactions depends on both its molecularstructure, the proximity and character of the light source, and the presence of other reactantcompounds.

Oxidation is a chemical reaction which involves the removal of electrons from a metal or otherchemical. Conversely, electrons are added to chemical substrates in reduction reactions. Bothoxidation and reduction reactions are significant in that they influence the mobility and fate ofchemicals in environmental matrices. Oxidized and reduced forms of the same chemical mayalso exhibit unique chemical, ecological, and/or lexicological properties (e.g., mercury).

5.2.2 Fate and Transport DataThis section summarizes the chemical characteristics and the available environmental fate andtransport data for organic and inorganic chemicals detected at the SRI site. The chemicalsdetected were grouped into two groups: organic and inorganic. The organic constituents weregrouped into four generalized classes sharing similar characteristics. These classes are:(1) chlorinated volatile organics, (2) nonchlorinated volatile organics, (3) semivolatiles (BNAs[base neutral/acid extractable compounds]), and (4) chlorinated pesticides and polychlorinatedbiphenyls. The following subsections provide a discussion of the characteristics of each classof compounds.

5.2.2.1 Organic CompoundsVolatile organics and semivolatile organics were detected in the environmental media samplesfrom the SRI site.

Volatile OrganicsBoth chlorinated and nonchlorinated VOCs were detected in groundwater, surface water, surfacesoils, subsurface soils, and sediments sampled during the site investigation. VOCs detectedduring laboratory analysis of various media are presented in Chapter 4.0, Nature and Extent ofContamination. Table 5-1 presents the parameters governing the environmental fate of theseindividual constituents.

EDK/ENG/ay071494.rpt 5-10SLR-0010608

Because of the differences in the physico-chemical properties of the two groups of compounds,their environmental fate and transport processes are discussed separately below.

• Chlorinated volatiles- Solubility. As presented in Table 5-1, the chlorinated VOCs associated with the

SRI site are highly water soluble. The high solubilities for these compounds aredue to their small molecular size, low molecular weights, and high polarity. Giventhe highly soluble nature of these compounds in water, surface runoff andgroundwater transport of chlorinated VOCs are principal environmental fateprocesses.

- Volatilization. Volatile chlorinated organics would be readily transported into theatmosphere from soils and water when in contact with the atmosphere.

- Adsorption/Desorption. The log K^ values are comparatively low for the volatileorganics (Table 5-1). Thus, adsorption to soils or organic matter is not a significantenvironmental fate process for die chlorinated solvents associated with the site.This does not imply that there would not be soil-associated volatile organics, butrather that the volatile organics associated with the soils would be miscible andhave the potential to be a source for groundwater and/or air contamination.

- Bioaccumulation. Bioaccumulation of volatile organics associated with the site soilsmay be of limited significance since BCFs for volatile compounds are generally low(Howard, 1990).

- Biodegradarion/Biotransfonnarion. The biodegradation of chlorinated volatilecompounds is typically a slow process (EPA, 1979). However, biodegradation ratesare generally faster than abiotic degradation rates (e.g., hydrolysis; Vogel, et al.,1987). Halogenated methanes and ethenes can all undergo oxidation transformationby bacteria and higher organisms (Vogel, et al., 1987). Reductive dechlorinationof chlorinated volatile compounds under anaerobic conditions is another significanttransformation process.

- Hydrolysis/Photolysis. Hydrolysis of chlorinated volatile compounds occurs veryslowly, with half-lives ranging tram approximately 0.1 to 3,500 years (Howard,1991). Direct photolytic degradation of chlorinated volatile organics viaphotodissociation is usually restricted to the stratosphere (EPA, 1979). In aqueousenvironments, direct photodissociation is generally negligible or nonexistent. Formost of the chlorinated VOCs associated with the site, photo-oxidation mediated byhydroxyl radicals would be the predominant process of degradation in theatmosphere (EPA, 1979). Therefore, photolytic degradation of chlorinated volatileorganics is not a significant removal mechanism for these compounds (Howard,1990).

- Oxidation. Direct oxidation of chlorinated volatile organics is generally aninsignificant process in natural environments (EPA, 1979). As mentioned


previously, photo-oxidation within die stratosphere is the predominant, thoughrelatively minor, degradation process.

• Nonchlorinated volatiles:

- Solubility. The nonchlorinated VOCs present in the environmental media at the siteare presented in Table 5-1. These compounds exhibit high water solubilities.Considering their highly soluble nature in water, surface runoff and groundwatertransport of these compounds will be the principal environmental fate processes atthe site.

- Volatilization. Because of their high vapor pressures, these compounds would bereadily transported into the atmosphere from surficial soils and surface water.

- Adsorption/Desorption. Adsorption to soils/sediments or organic matter is generallynot a significant environmental fete process for nonchlorinated volatile compounds.They exhibit low K^ and low K^ coefficients, indicating a low affinity foradsorption to organic matter (Table 5-1). Low K^. values coupled with the highwater solubility and volatility of most of these compounds make adsorption aninsignificant environmental fate process, in relation to water and airborne transportmechanisms.

- Bioaccumulation. Bioaccumulation of the nonchlorinated volatile organicsassociated with site soils may be a limited fate process, since BCFs for mostnonchlorinated VOCs are generally low (Howard, 1990).

- Biodegradation/B iotransf ormarion. Slow biodegradation of these compounds occursvia microbial processes or metabolic pathways of higher organisms. Underanaerobic conditions, slow degradation has been reported for these compounds(Howard, 1990).

- Hydrolysis/Photolysis. Hydrolysis of these compounds generally does not occur(EPA, 1979). Direct photodissociation within aqueous and/or atmospheric matricesis typically insignificant or negligible (EPA, 1979).

- Oxidation. Direct oxidation of these compounds associated with the site isgenerally an insignificant process in natural environments (EPA, 1979).Photooxidation within the stratosphere is the predominant (though relativelyinsignificant) degradation process.

Semivolatile OrganicsSemivolatile organic compounds were detected in the environmental media analyzed from thesite. These included phthalate esters (e.g., bis(2-ethylhexyl)phthalate), polyaromatic hydrocarbons(PAH) (e.g., pyrene), and phenolic commpounds (e.g. phenol). Semivolatile organic compounds'detected during laboratory analysis of the various environmental media are presented in

EDIS/ENG/ay0714M.rpt 5-12

SLR-0010610

Chapter 4.0, Nature and Extent of Contamination. Table 5-1 presents the environmental fateparameters for these individual constituents. The processes controlling the fate and transport ofthese contaminants in the environment are discussed in the following sections.

• Phthalate Esters: Phthalate esters were detected in various environmental matrices atthe SRI site. These compounds are presented in Chapter 4.0, Nature and Extent ofContamination. Table 5-1 presents parameters governing the environmental fate ofthe individual constituents detected.

- Solubility. Phthalate esters are typically some of the more soluble BNAs, primarilydue to their low aromaticity (i.e., only one benzene ring) and the high polarityimparted to the molecule by the diester linkage. However, compared to the VOCsat the site, the solubility of phthalate esters is generally low (Table 5-1). Variabilityin aqueous solubility among die different phthalate esters depends upon thehydrophobia character of the functional groups attached to the diester linkage.Phthalate esters readily form complexes with fulvic acids which result in fulvicacid-phthalate complexes which are very soluble in water (EPA, 1979).

Because of their generally low solubilities, runoff and groundwater transport of thephthalate esters will not be an important environmental fate processes at the site.

- Volatilization. In general, phthalate esters are not very volatile. Due to their lowvolatilization rates, as indicated by their Henry's Law constants and vapor pressures(Table 5-1), volatilization of phthalate esters at the site will not be a significantenvironmental fate process.

- Photolysis. Direct photolysis of phthalate esters is unlikely to occur, and indirectphotolysis via hydroxyl radical interaction with the aromatic ring is a negligibleprocess in the natural environment (EPA, 1979). Thus, photolysis would be anenvironmentally insignificant degradation process for these compounds at the site.

- Oxidation. No information was found in the literature to suggest that oxidation isa significant environmental fate process for phthalate esters in the naturalenvironment.

- Hydrolysis. Phthalate esters are susceptible to hydrolytic reactions, but thesereactions typically proceed at such a slow rate (e.g., half-lives on the order of years)that hydrolysis of these compounds is not significant in the natural environment(EPA, 1979). In general, the hydrolysis rate is slower for longer-chain esters andmay be catalyzed by both acids and bases (EPA, 1979). The low hydrolysis ratesof the compounds detected in water samples at the site may relegate thisenvironmental fate mechanism to one of little importance.


- Adsorption/Dcsorption. Some of the phthalate esters detected in the environmentalmedia at the site readily adsorb to organic matter and soil particles. The tendencyto readily adsorb to organic matter is reflected by high K^. and K^ partitioncoefficients for these compounds (Table 5-1) (EPA, 1979). The high bindingaffinity of phthalate esters to soil is substantiated by the analytical data forphthalates in the on-site soils and stream sediments. Therefore, the adsorption ofphthalate esters to organic matter and/or soil particles will be an importantenvironmental fate process at the site.

- Bioaccumulation. Bioaccumulation and/or bioconcentration of phthalate esters isgenerally of importance when discussing environmental fate and transport processes.The potential for the bioaccumulation of phthalate esters in plants or animals maybe assessed by the K^ values of individual compounds (Table 5-1). Compoundswith low K^ values generally have small BCFs, thus have little tendency tobioaccumulate.

- Biodegradation/Biotransformation. Biodegradation is a significant environmentalfate process for the phthalate esters associated with the site. Phthalate esters aredegraded under most conditions by microbial populations and/or metabolized bymulticellular organisms (EPA, 1979). Microbial degradation occurs readily underaerobic conditions, and more slowly under anaerobic conditions, with rates greatlyincreasing if the compounds are utilized as sole carbon sources (EPA, 1979).

• PAHs: The PAHs at the site were detected in soils and groundwater. Thesecompounds are presented in Chapter 4.0, Nature and Extent of Contamination.Table 5-1 presents parameters governing the environmental fate of these individualconstituents.

- Solubility. As presented in Table 5-1, the solubility of PAH compounds is highlyvariable and is a function of molecular structure, degree of aromaticity, and type offunctional groups attached to the parent molecule. Generally, solubility is positivelycorrelated with molecular polarity and negatively correlated with degree ofaromaticity. With some exceptions, BNAs, including PAHs, are less soluble thanacid extractable compounds.

BNAs exhibiting the highest water solubilities are those containing highly polarfunctional groups (e.g., amino, carboxyl); whereas, the compounds showing thelowest water solubility have a high degree of aromaticity (e.g., polycyclicaromatics). Therefore, runoff and groundwater transport of PAHs are not significantprocesses at this site.

- Volatilization. Table 5-1 indicates that the PAH compounds have low vaporpressures (e.g., ranging from 10"2 to 10"6 torr) and, thus, would not tend to volatizeunder normal environmental conditions. The rate of vaporization of PAHcompounds with four or more benzene rings is expected to be insignificant relativeto the evaporation of lower molecular weight compounds such as naphthalene (EPA,1979).


- Adsorption. The PAHs have high K^. values and, thus, readily adsorb to soils andsediments (Table 5-1). Migration of particle-associated PAHs would be controlledby the slow-leaching of PAHs to percolating water and any gross particlemovements such as surface soil runoff.

- Bioaccumulation. Bioaccumulation and/or bioconcentration of PAHs is generallyof importance when discussing environmental fate and transport processes. Thepotential for the bioaccumulation of PAH compounds in aquatic or terrestrial floraand fauna may be assessed from the K^ of the respective chemicals (Table 5-1).Compounds with high K^ values generally have a tendency to bioaccumulate.

- B iodegradarion/B transformation. Biodegradation of PAHs represents a significantenvironmental fate process. PAHs can be biotransformed by higher organisms andmicrobial populations to more water soluble derivatives and/or compounds of lowermolecular weight (Howard, 1990).

- Hydrolysis/Photolysis. Hydrolytic reactions occur slowly for PAH compounds(Howard, 1990); therefore, they would not be considered a significant environmentalfate process for PAH compounds at this site. It should also be noted that PAHcompounds do not contain groups that are amenable to hydrolysis (EPA, 1979).

• Chlorinated Pesticides and Polychlorinated Biphenyls (PCBs): Six chlorinatedpesticides were detected in environmental matrices analyzed from the SRI site. Theseconstituents were aldrin, alpha-BHC, alpha chlordane, gamma chlordane, heptachlorand heptachlor epoxide. Four aroclor mixtures were detected in environmentalmatrices analyzed from the SRI site. These included aroclors -1016, -1221, -1254,and -1260. The processes controlling the fate and transport of these constituents inthe environment are discussed in the following sections.

- Solubility. Chlorinated pesticides and PCBs are relatively insoluble compared withother organics in general, and with other organics found at the site (Table 5-1).Solubility decreases with increasing chlorination and decreasing temperature.Variations in solubilities are due principally to differences in molecular structureand polarity (resulting from the degree of chlorination). The level of sorption tosediments and biota in aquatic systems indicates that chlorinated pesticides andPCBs are not very soluble in water. Also, due to a low solubility in water, thegreatest concentrations of chlorinated pesticides and PCBs are found sorbed tosuspended and benthic sediments in aquatic systems. The range of solubilities forchlorinated pesticides and PCBs indicate that groundwater transport of theseconstituents is most likely not an important fate process for the SRI site.

- Adsorption/Desorption. Adsorption to soils/sediments or biota is the primaryenvironmental fate and transport process for the majority of the chlorinatedpesticides and PCBs found at the site. As indicated in Table 5-1, the tendency ofthese chlorinated compounds to be adsorbed is reflected in the partition coefficients(high K^. and Kow values). In general, these constituents, once adsorbed, wouldremain bound, rarely becoming desorbed from soils or sediments. It has also been

EDIS/ENG/ay«71494.rpt 5-15SLR-0010613

found that these constituents are more tightly bound to soils having a relativelyhigher organic content (Esposito, 1980; EPA, 1979).

Bioaccumulation. Bioaccumulatioa and/or bioconcentration of chlorinated pesticidesand PCBs is generally of importance when discussing environmental fate andtransport processes. The potential for the bioaccumulation may be assessed by theirK^ values (Table 5-1). In general, compounds with higher Kow values have atendency to bioaccumulate. Numerous studies have shown these compounds tobioaccumulate with the more highly chlorinated isomers having a greaterbioaccumulation tendency (Le., a higher Kw) (Esposito, 1980; EPA, 1979). Also,since these compounds are adsorbed strongly to organic sediments, they are readilybioaccumulated by organisms closely associated with sediment (e.g., benthicmacroinvertebrates).

Biodegradation/Biotransformation. Chlorinated pesticides and PCBs show varyingdegrees of susceptibility to biodegradation and biotransformation. Studies indicatethat these compounds may be partially degraded in soils; however, the highlychlorinated species are more resistant to biodegradation or biotransformation(Esposito, 1980; EPA, 1979). The resistance of chlorinated pesticides and PCBs tomicrobial degradation indicates that biodegradation/ biotransformation is not asignificant environmental fate for these compounds at the site.

Volatilization. The low vapor pressures and Henry's Law constants for thechlorinated pesticides and PCBs detected at the SRI site (Table 5-.1) indicate thatvolatilization is not an important environmental fate process for these constituents.Studies have shown that loss of these constituents by volatilization is extremely low(Esposito, 1980; EPA, 1979). However, although empirical evidence shows thatvolatilization under natural conditions is extremely slow, the lack of destructionprocesses for these compounds indicates that volatilization may attribute to theirdistribution (EPA, 1979).

Hydrolysis/Photolysis. Hydrolysis of chlorinated pesticides and PCBs is not likelyunder environmental conditions. PCBs are especially resistant to acidic and basichydrolysis. Hydrolysis does not appear to be important in terms of environmentalfate for these compounds (EPA, 1979).

For PCBs, it is possible that photolysis of the more highly-chlorinated biphenyls canoccur. However, the process of such breakdown is slow (EPA, 1979).Consequently, the extent to which photolysis affects the environmental fate of thesechlorinated biphenyls at the site is inconclusive.

Oxidation. Chlorinated pesticides and PCBs associated with the SRI site areresistant and generally not subject to oxidation in the environment (EPA, 1979).Consequently, oxidation is not considered a process which will affect theenvironmental fate and transport of these compounds.

EDIS/ENG/ay0714M.rpt 5-16

SLR-0010614

SummaryChlorinated VOCs are in general very miscible and not very persistent in the environment,principally due to their high volatility, low adsorption to soils, and high water solubility. Overall,solubility is likely the most important fate and transport mechanism for chlorinated VOCs. Dueto the high mobility of chlorinated VOCs, a decrease in their concentrations in the variousmatrices is anticipated with time as long as there is no additional input of these compounds.

The nonchlorinated VOCs found at the SRI site are generally mobile and not very persistent inthe environment due to their high volatility, low adsorption to soils, and high water solubility.Overall, solubility is likely the most important fate and transport mechanism for nonchlorinatedVOCs.

In general, phthalate esters associated with the SRI site are relatively persistent in soil matrices.This is primarily due to their high affinity for organic matter and soil particles, low watersolubility, resistance to photolytic, oxidative and hydrolytic degradation, and low volatilizationrate. However, once desorbed from soil, phthalate esters would not persist appreciably due totheir low water solubilities and susceptibility to microbial degradation. Microbial degradationmay occur under certain environmental conditions leading to a decrease in phthalate esterconcentrations. Accordingly, a decrease in these compounds' concentrations is expected at thesite, albeit at a slower rate relative to volatile organics.

There is some limited evidence to suggest that long-term bioaccumulation or biomagnificationmay occur and the available literature data indicate that phthalate esters are bioaccumulated overthe short term by a variety of organisms. It is known that phthalate esters are concentrated toan appreciable level by higher animals (including man) in specific tissues and organs; however,they are rapidly metabolized (EPA, 1979).

In general, many of the PAH compounds in aqueous and/or atmospheric matrices are vulnerableto direct photolysis and/or photooxidation (EPA, 1979). The low solubility of these compoundsin water generally relegates this environmental fate mechanism to one of lesser importance.

Chlorinated pesticides and PCBs are relatively insoluble compared with other organics in general,and with other organics found at the site. Water solubility decreases with increasing chlorinationand decreasing temperature for these compounds. Water solubility of these compounds indicatesthat groundwater transport may not be an important fate process for transport from the SRI site.The processes of photolysis, hydrolysis, oxidation, biotransformation, and biodegradation are not


likely to be major factors in determining the environmental fate of these compounds at the SRIsite. Chlorinated pesticides and PCBs are lipophilic compounds that have a tendency tobioaccumulate in organisms. Bioaccumulation is directly related to the octanol/water portioncoefficient (Table 5-1), which shows that this process is generally important when discussing theenvironmental fate and transport of these compounds. The chlorinated pesticides and PCBsdetected at the site are persistent chemicals which have a tendency to adsorb to soils and organicmatter. Sorption appears to be the dominant environmental process affecting the fate of thesecompounds.

5.2.2.2 Inorganic AnalytesNumerous inorganics were detected in the aqueous and soil/sediment matrices of the SRI site.Many of these compounds are normal constituents of soil/sediment parental material or commonconstituents in aqueous matrices due to leaching from soil/sediment This section presentsenvironmental fate data for inorganics that may not be common or normal constituents of the site.For selected metals, relevant data that impact environmental fate and transport are presented asfollows (from EPA, 1979):

• Solubility/Aqueous Chemical Speciation. In general, the aqueous speciation of metalsdepends primarily upon the relative stability of individual valence states (which areelement-specific), oxygen content, pH and Eh (oxidation-reduction potential)conditions, and the presence of available complexing agents. The predominantdissolved species of the elements in aqueous systems are usually deduced fromgeochemical equilibrium models. The distribution of these species is commonlyexpressed by Eh-pH diagrams. To determine the potential for a metal to exist at thesite in the aqueous or immobile form and its potential oxidation state, a set ofequilibrium equations would be required to be developed for that element. However,for a rapid assessment, the site-specifics, Eh and pH, may be imposed on an existingEh-pH diagram, given that the conditions assumed to construct the diagram(concentration of the element and other coexisting ions) are not very different fromthe conditions at the site.

• Volatilization. Antimony, arsenic, mercury, lead, and selenium are capable of beingbiomethylated, and the methylated derivatives of these elements can volatilize. Oncein the atmosphere, removal of volatilized organometallic compounds is principally viawet and/or dry deposition. Additionally, arsenic under extremely reducing conditionscan exist as arsine gas (AsH3) which is volatile. However, this compound, onceformed, is rapidly oxidized in aerobic conditions.

In summary, limited volatilization of biomethylated antimony, arsenic, mercury, lead,and selenium may occur at the site. For all other metals associated with the site,volatilization will not occur. While limited volatilization of antimony, arsenic,mercury, lead, and selenium compounds is possible, volatilization of these compounds

EDIS/ENG/ay0714«M.rpt 5-18SLR-0010616

would be an insignificant environmental fate process, considering existing siteconditions.

Photolysis. Photolytic reactions do not occur for arsenic, beryllium, cadmium, lead,nickel, selenium, silver, and thallium. Some copper compounds are photosensitive;however, there are insufficient data at this time to conclude that photolysis is animportant degradative mechanism for copper-containing compounds. Considering siteconditions, photolysis would be an insignificant degradation process.

Adsorption/Desorption. In general, metals readily adsorb to inorganic mineralsurfaces and organics. Adsorption for most metals is highly pH dependent, withdesorption being favored at low pH and adsorption dominating at higher pHconditions. The types of clays, their surface areas, and surface changes dictate theextent of the adsorption (Karickhoff et al., 1979). Consequently, adsorption alsovaries with chemical speciation.

Complexation. In general, the metals of interest associated with the site are capableof forming numerous inorganic and organic complexes in the natural environment.All of the metals of interest readily form organo-metallic complexes, especially withnaturally occurring organic acids (e.g., humic and fulvic acids). Some of the metalsassociated with the site may form metaUo-inorganic complexes with inorganic ligandssuch as carbonate, chloride, hydroxyl and sulfate (e.g., copper, lead, arsenic, andcadmium). Among lead, arsenic, copper and cadmium, metallo-organic complexformation is usually favored over metallo-inorganic complexes. Beryllium typicallyforms complexes with hydroxide ions and may, at elevated pH, form polynuclearhydroxide complexes with me inorganic ligands hydroxide, carbonate, and sulfate.All of the various complex formations mentioned above alter the aqueous solubilitiesof the metals of interest. Therefore, complexation with various organic and inorganicligands is a significant environmental fate process for the metals of interest at the site.

Precipitation/Co-precipitation. Precipitation and/or co-precipitation are importantremoval mechanisms of dissolved aqueous metal species. Co-precipitation withhydrous iron, manganese, and/or aluminum oxides may occur for arsenic, cadmium,copper, and beryllium, particularly under nonreducing or basic conditions. Also, inreducing environments, thallium may precipitate as a sulfide.

With regard to precipitation, cadmium typically precipitates as Cd(OH)2 above pH 9,CdO2

2" above pH 10, and CdS under reducing conditions. In the environment, copperusually precipitates as malachite [Qij (OH)2 CO3], whereas lead may precipitate ascerussite (PbCO3) and/or anglesite (PbSO , depending upon environmental conditions.Beryllium may precipitate as the insoluble hydroxide or oxide. Considering theabove, and depending upon numerous aqueous environmental conditions (e.g., pH,metallic and anionic species present, etc.), precipitation and/or co-precipitation can beimportant environmental fate processes for the metals associated with the site. Thisphenomenon would be reflected in comparison of filtered and unfiltered watersamples.

EDK/ENG/ay071494.rpt 5_19SLR-0010617

Canonic Exchange. All the metals of interest are capable of undergoing isomorphicsubstitution with cations present in the lattice structure of crystalline soils andsediments. This process can be an effective means of removal from solutiondepending upon environmental conditions. Similar to sorption processes, numerousfactors such as pH, organic content, and type of soil will influence cationic exchange.

• Biotransformation/Biodegradarion. Biomethylation of lead and arsenic mediated bymicrobial populations can occur to a limited extent in the environment and thisprocess may occur under aerobic and/or anaerobic conditions. Additionally, biogenicligands have been reported to form complexes with some metals, particularly withlead. Biotransformation of copper does not occur, and cadmium can be complexedin vivo by polydentate ligands that are normally involved in the binding skes ofessential metal ions such as iron, copper, zinc, manganese, etc. Antimony is onlyslightly bioaccumulated and has been little studied in aquatic organisms. Also, asmentioned, biomethylation of antimony could occur in the environment.Biotransformation of selenium may result in methylation with subsequentvolatilization, as mentioned previously. The other metals of interest at the site are notsusceptible to biotransformation mechanisms.

The potential for inorganic constituents to migrate in groundwater is related to each constituent'sdistribution coefficient (Kd). Kj values for commonly encountered inorganics range from nearzero to 1,000 milliliters per gram (mL/g) or greater. Inorganic solutes in groundwater areessentially immobile with Kj values mat exceed 100. Kj values between 0.1 and 50 mL/gsuggest moderate mobility in groundwater, while Kj values below 0.1 mL/g suggest highmobility. Generally, trace metals have a very high potential for immobility (i.e., retardation).Cations are moderately immobile, and anions are the most mobile in groundwater as they havelow retardation factors (Walton, 1985).

A list of potentially toxic constituents detected at the SRI site is presented below, with associatedKd values (Baes, et al., 1984) and potential mobility in groundwater.

SummaryIn general, the metals of interest associated with the SRI site are typically persistent withinenvironmental matrices. This persistence is primarily related to recycling mechanisms withinenvironmental matrices for some metals (e.g., arsenic, lead, and copper), and removalmechanisms (precipitation, cationic exchange adsorption, etc.) which decrease mobility.Chemical speciation of metals in the environment can result in metal concentrations in both solidand aqueous media or preferential presence entirely in one medium.

Among the mechanisms described above, only solubility/aqueous chemical speciation,adsorption/desorption, complexation, precipitation/co-precipitation, and cationic exchange havethe potential to significantly influence the fate and transport of the metals of concern at the SRIsite.

Depending on how the metals from the site enter the environment, some metals may persist inthe environment near the source area longer than the others. For example, some metals (e.g., ironand manganese) may enter the soil aquifer under a highly reduced condition. These dissolvedmetals would be expected to migrate in the groundwater until the pH and Eh conditions becomefavorable to precipitate forms of these metals (e.g., surface water seeps create conditions wheremetals are oxidized and precipitate out of solutions). These metals may also enter the bedrockwhile they are in the aqueous phase. If dissolved metals enter the bedrock, they would beexpected to migrate long distances (through the fractures in the bedrock) due to the morechemically reduced conditions and the lower percentage of naturally occurring organic matter inthe bedrock.

5.3 Contaminant MigrationThe migration of volatile organic compounds and inorganic analytes is controlled by the localnydrpgeology. As discussed in Chapter 3.0, groundwater from the area of the former disposal


cell moves to the east toward the eastern wetlands. The concentrations of volatile organics thathave been detected in the monitoring wells are lower than their solubility limits (Table 5-1).Therefore, these contaminants are transported in their soluble form, rather than as free phasecompounds.

The following sections discuss the horizontal and vertical migration of volatile organiccompounds from the former disposal cell area.

5.3.1 Lateral Migration of Volatile Organic CompoundsVolatile organic compounds have migrated downgradient from the former disposal cell area ina relatively narrow plume. Based on the data presented in Chapter 4.0, most of the volatileorganic compounds have been detected in wells that are located on flow lines (based on waterlevel maps) leading downgradient from the source area on the SRI. High concentrations ofvolatile organic compounds were detected in monitoring wells MW-05S, MW-05I, MW-07S,MW-07I, MW-07D, MW-08S, B-3W, and DM-8S. These wells are located downgradient of theformer disposal cell. Other data that support this interpretation of the width of the plume are theabsence of contamination in wells MW-04S, MW-04D, DM-IOS and DM-IOD which are notdirectly downgradient of the former disposal cell area. The lateral limits of the projected plumeare interpreted near wells where contamination has not been detected. However, the plume isshown to increase in width downgradient of the former disposal cell because of hydrodynamicdispersion of the contaminants. Figure 5-1 shows the lateral extent of volatile organiccontamination.

The leading edge of the plume has not been defined. The presence of contamination in wellsMW-OS, MW-OI, MW-OD and MW-OS indicate that the plume has migrated as far as the westernedge of the eastern wetlands. The absence of contamination in well DM-9 indicates that theplume has not migrated as far as DM-9. However, based on the groundwater contour maps, wellDM-9 is not directly downgradient of the former disposal cell area.

5.3.2 Vertical Migration of ContaminantsThe vertical migration of dissolved contaminants is a function of the hydraulic gradient, thedirection of groundwater movement, and the ratio of horizontal to vertical hydraulic conductivity.The vertical gradient has been measured to be both upward and downward at the SRI site. Adiscussion of the vertical hydraulic gradient is presented in Chapter 3.0.

The specific gravity of each of the volatile contaminants detected in the site wells is listed onTable 5-1. Thus, in a separate phase, or at concentrations approaching the contaminantssolubility limit (see Table 5-1), these compounds would be expected to sink in the aquifer.However, density is not a factor in the vertical migration of dissolved volatile organiccontaminants in the plume because the concentrations are too low.

The data indicates that the further the plume migrates away from the former disposal cell, thedeeper the contamination moves. This could be the result of several factors. Figure 5-2 wasprepared to present a view of the approximate extent of vertical contamination. This figureshows that contamination is present in well MW-OI but not in MW-OD. This could be a resultof the till that is situated between the two screen zones. It is possible that the contamination ismigrating downward in the area of MW-0 until it encounters the till layer. The contaminantsthen migrate above the low permeable till layer until the till pinches out. The contaminationcontinues to migrate downward, after the till pinches out, and into the bedrock.

The downgradient edge of the plume has not been delineated. As mentioned above, Figure 5-2has been prepared to present the approximate extent of vertical migration of contaminants.However, well Cluster MW-0 is not directly downgradient of the former disposal cell. Wellcluster MW-0 was used in this cross-section because it contains the only bedrock well east of theformer disposal cell. Monitor well MW-OS appears to be directly downgradient of the formerdisposal cell, but MW-OS is not paired with a deeper well. Therefore, the presence ofcontamination in the bedrock at the MW-OS location is unknown. It is possible that there arehigher contaminant concentrations in the bedrock at the MW-OS location than found at wellcluster MW-0. The contamination in MW-0 could be attributed to the east-northeast directionof groundwater flow in the bedrock. However, it is impossible to define the leading edge andvertical extent of the contaminant plume without additional wells.

The vertical hydraulic gradient measurements collected during this investigation suggest a strongtendency for an upward vertical gradient in the former disposal cell area. However, both of thesemeasurements were taken in autumn. It is possible that in the spring, when there is moreprecipitation, the vertical hydraulic gradient is downward. A seasonal downward gradient wouldassist in substantiating the presence of contaminants in the lower part of the overburden aquiferand the upper part of the bedrock aquifer.

5.3.3 Downgradlent Migration of ContaminantsAs part of the RI, calculations were used to assess the extent of downgradient migration ofvolatile organic compounds. The prediction of the downgradient extent of contaminant migrationfrom the SRI was calculated using an average groundwater velocity of 0.50 feet per day in thedeep overburden and the retardation factor of five of the contaminants detected in the monitoringwells. The formula used was:

Ve = V/RD

where: RD = 1 + Kd f/nn = porosity (dimensionless)y = Bulk density g/cm3

Kd = %oc'Y^V = 0.50 feet/day (velocity of groundwater in the deep overburden near the

former disposal cell)D = 1+Kdy/nOC% = % Organic Content (From Site Specific Average)Vc = velocity of a particular contaminant

The results of the calculations are presented in Table 5-2. The calculations show thattrichloroethene migrates at a rate of 0.02 feet/day (slowest moving contaminant) and acetonemigrates at a rate of 0.32 feet/day (fastest moving contaminant). These calculations do notconsider biotransformation or chemical degradation and are limited to contaminant migration inthe overburden.

6.0 Baseline Risk Assessment

6.1 Public Health EvaluationThe human health risk assessment for the SRI site in Lisbon, New York is based on theanalytical results obtained from the sampling efforts from the SRI site and collection of off-siteresidential well water samples from homes adjacent to the site. This risk assessment providesan analysis of baseline risks if no further action is taken at the site and to assist in establishingremedial goals, if necessary. Procedures and methodologies used in this risk assessment complywith the following USEPA guidance documents:

• USEPA (U.S. Environmental Protection Agency), 1989, Risk Assessment Guidancefor Superfund, Vol I., Human Health Evaluation Manual (Part A), Office ofEmergency and Remedial Response, Cincinnati, OH, EPA/540/1-89/002.

This human health risk assessment provides a conservative approach which approximatescarcinogenic risk and noncarcinogenic hazard estimates for some sub-populations of potentiallyexposed receptors. Upper bound estimates of potential health risks are calculated for bothpresent-use and future-use exposure scenarios. If potential health risks estimated by theseconservative "reasonable maximum exposure" and risk analysis methodologies are above the EPAtarget levels (i.e., l.OE-04 for carcinogenic risk and 1.0 for the non-carcinogenic hazard index),then an average case scenario (Central Tendency Exposure) is analyzed and presented forexposure pathways exhibiting excessive risk.

EDIS/ENG/ay071494.rp6SLR-0010627

This human health risk assessment chapter of the RI report is divided into the following fivesections:

• Section 6.1.1 (Identification of Constituents of Concern) provides the availableanalytical database and the identification of constituents of concern (COC);

• Section 6.1.2 (Exposure Assessment) addresses the physical components of thesite and the exposure pathways by which site-related constituents may reachhuman exposure points;

• Section 6.1.3 (Toxicity Assessment) summarizes and reviews relevant toxicityinformation for each of the COC;

• Section 6.1.4 (Risk Characterization) combines information from previoussection to quantitatively characterize the health risks associated with exposureto media from the SRI site.

• Section 6.1.5 (Uncertainty Analysis) discusses the uncertainty and inherentassumptions that impact the risk analysis of the SRI site.

• Section 6.1.6 (Summary) of this risk assessment are summarized and re-statedin this section.

6.1.1 Identification of Constituents of Concern6.1.1.1 Data CollectionAs stated in Chapter 2.0 of this document, an extensive field investigation was initiated tocharacterize the extent of constituents present and the potential for migration from the site.These investigations included collection of samples of on-site soils and groundwater, and the off-site collection of sediment, surface water and groundwater samples. Samples collected wereanalyzed for the presence of metals, volatile organic constituents, semi-volatile constituents,pesticides and PCBs.

Appendix G provides information detailing selection of COCs, exposure assessment parametersused, and media-specific exposure pathway risk and hazard characterizations for the SRI site.Appendix H is a compilation of the COC toxicity profiles.

The sampling processes performed at the SRI site during the phased remedial investigations forthe risk characterizations and analysis are described below:

EDIS/ENG/ay071494.rp6 6-2SLR-0010628

SoUSoil samples collected within the top three feet were utilized for assessing risks to on-sitetrespassers and off-site residents and potential future users of the SRI site if no remedial actionsare to be initiated.

A total of 42 surficial soil samples comprise the soil database for this risk assessment. Thesesamples were collected from hand auger borings and hollow-stem auger borings throughout theSRI site between September 1992 to December 1992, and September 1993 to December. 1993.It should be noted that these soils borings were located with a bias toward areas of suspectedcontamination, and as such, represent "worst case" conditions as opposed to average conditionsexpected throughout the site.

GroundwaterThe groundwater database for this RI is comprised of two separate data sets, on-site groundwaterand off-site groundwater. Two rounds of groundwater quality samples were collected from on-site overburden monitoring wells (including the leachate sump) and on-site bedrock monitoringwells. Two rounds of off-site residential well sampling and analysis were conducted tocharacterize the quality of the groundwater used in local residences adjacent to the SRI site. Adetailed description of the groundwater sampling was presented in Chapter 2.0.

As there are no current exposure pathways for on-site groundwater units, these data were notaddressed separately in this risk assessment.

The off-site residential wells adjacent to the SRI site were sampled twice during this RIinvestigation and die New York State Department of Health has established baseline waterquality data for the residential wells through several rounds of sampling and analysis over aperiod of years. The results of these studies demonstrate that off-site residential wells are notimpacted by site-related contaminants at this time. Because site-related constituents are notimpacting off-site residential wells at this time, no quantitative risk analyses were conducted foroff-site resident groundwater usage in the current land-use scenarios.

However, both on-site and off-site groundwater data sets were combined to present a conceptualsimple groundwater source for potential future land use scenarios (USEPA, 1994). Thishypothetical groundwater data set was used to evaluate and characterize the risk/hazard of bothoff-site and on-site residential usage of groundwater in the future land-use scenarios.

EDIS/ENG/ay071494.rp6 6-3SLR-0010629

Surface Water/SedimentSixteen surface water and sediment sampling stations were established in the southwesternwetland area the southern boundary of the SRI site. Two additional sampling stations wereestablished in the northwestern wetland area. The 18 sampling stations were sampled during asingle event, corresponding to the ecological field investigations.

6.1.1.2 Data Validation and EvaluationThe analytical data from this remedial investigation were evaluated by independent datavalidators. Results of these validators' scrutiny are data sets with qualifiers that describe thequality of the data strictly from an analytical chemistry quality assurance viewpoint.

Data with the following qualifiers were included as detected concentrations in their respectivemedia:

"J" - estimated concentration;

"B" - (inorganic data) compound detected above instrument detection limit butbelow the contract required detection limit;

"B" - (organic data) indicates detection of the same compound in the associatedblank;

"E" - presence of interference for inorganics or exceedence of a calibration rangeof the GC/MS instrumentation for organics;

"D" - analysis conducted at a secondary dilution factor;

"M" - duplicate injection precision was not met;

"S" - spiked sample recovery was not within control limits;

"*" - duplicate analysis is not within control limits;

"+" - correlation coefficient for the Method of Standard Additions is less than0.995; and

"W" - Post-digestion spike is not within control limits.

EDIS/ENG/ay071494jp6 6-4SLR-0010630

Data reported as not detected, indicated by a "U" qualifier, were not included in the database.Data with an "R" qualifier, indicating a rejected value, were not included in the database. Allother data, regardless of the respective qualifier, are considered in the development of thedatabase.

A number of steps were taken in the evaluation of validated data for useability of samplesanalyzed from the SRI site to determine whether reported concentrations are of acceptable qualityfor use in the quantitative risk assessment. Prior to any statistical analysis, the data werereviewed to determine the representativeness of the sample population, and the useability ofindividual values. Inspection of the validated groundwater data sets indicated the analyticalresults for volatile organic constituents in two groundwater samples were very different from therest of the data set. Volatile organics such as benzene and vinyl chloride had detection limitsin monitoring well samples SSMW5IGI02 (10/19/93) and SSMW5GS01 that were, respectively,10,000 and 2,500 times greater man the typical detection limit of 1 ug/f for such constituents.These very high detection limits were due to dilution factors encountered in reporting the analyteacetone results. Acetone was quantitated at 2,100,000 ug/( in sample SSMW5IGI02. Analyticalresults for other classes of analytes (e.g. metals, semi-volatiles) were also suspect in these twogroundwater samples because matrix interferences and detection limits exceeded the highest valuefor certain analytes in other samples in the data set. Therefore, acetone values for these twogroundwater samples were included, but all other analytes were excluded from the statisticalanalyses for risk assessment of on-site groundwater.

To generate constituent concentrations that are conservatively representative of the SRI site, one-half the detection limit of all non-detects meeting the above criterion were also used. Byapplying the above evaluation procedures, a set of constituents was identified from the datacollected at the SRI site that qualify for inclusion in the quantitative risk assessment. Tables 6-1through 6-6 lists frequency of detection, arithmetic mean, range, and 95% upper limits ofconstituents detected at least once in surficial soil, off-site groundwater, surface water, sedimentsamples and the combined groundwater data sets from the site.

Notes:a. If the number of records is less than 102 indicates some of the analytical data were rejected by data validator.b. 95% Confidence Limits ware calculated using the H - Statistic method.c. Concentration Used in Risk Assessment Screening were calculated whan the detected frequency was greater than 5%.d. If the detected highest value is smaller than confidence Nmit, the highest value is selected instead of confidence limit for risk assessment.

The constituent concentrations that were included in the data set were analyzed statistically andthe arithmetic mean and the 95% upper confidence limit (UCL) of the arithmetic mean of lognormal data were calculated. The lower of either the 95% UCL or the maximum value ofconstituents in each medium were utilized in calculating the Reasonable Maximum Exposure(RME) to any receptor population or for calculating the Central Tendency Exposure (CTE), ifneeded. As specified in "Supplemental Guidance to RAGS: Calculating the Concentration Term"(USEPA, 1992) and using the H-statistic table in Gilbert (1987) to interpolate H values, thefollowing equation was used to calculate the 95% UCL:

95% UCL - e& * 05*2

where:UCL = upper confidence limite = base of the natural log (2.718)x = mean of the transformed datas = standard deviation of the transformed dataH = H statisticn - - = number of samples

6.1.1.3 Data Screening ProceduresIn an effort to focus the risk assessment on constituents of concern (COCs) that would contributemost of the risk, two procedures were employed to reduce the number of potential constituentsof concern. Both procedures are in accordance with data evaluation methodology for baselinehuman health risk assessments for CERCLA sites (USEPA, 1989a).

The first step was to eliminate constituents from the data sets if they were detected in less than5% of the samples collected for a specific environmental medium (i.e. sediment or surficial soil).Exceptions to this first step were the inclusion of all Class A carcinogens, regardless of theirdetection frequency, and inclusion of constituents mat do not have oral toxicity values from IRISor HEAST but were detected at a frequency greater than 5% in a medium of concern. Thesecond step used to reduce the number of constituents for the quantitative risk analysis employeda toxicity-concentration screening procedure. The toxicity-concentration screening procedureevaluates each identified constituent in terms of its overall contribution to the carcinogenic ornon-carcinogenic hazard in each environmental medium. The predominant route of exposure,ingestion, is utilized to quantify risks for the five environmental medial for screening purposes.The highest concentration value for each constituent obtained from the chemical analyses is used

EDIS/ENG/ay071494.ip6 6-24SLR-0010650

in the screening procedure. Standard USEPA formula and default parameters for ingestion ofsurficial soil, surface water, sediment, off-site groundwater, and combined groundwater were usedto quantify the carcinogenic risks and non-carcinogenic hazards associated with each constituent.Any individual constituent that contributed greater than 1% of the total media-specific risk orhazard was defined as a constituent of concern for that specific media. Those constituents thatcontributed less than 1% of the total calculated risk/hazard were eliminated from furtherconsideration.

The primary source for toxicity values (slope factors and chronic reference doses) were theIntegrated Risk Information System (IRIS, 1994). If a toxicity value for a given constituent isnot available from IRIS, the secondary source was the Health Effects Assessment SummaryTables (HEAST, 1993). Lastly, the USEPA Environmental Criteria and Assessment Office(ECAO) was contacted for interim guidance toxicity values not available from IRIS nor HEAST.

Each constituent's CAS number, the USEPA weight-of-evidence carcinogen classification, cancerpotency slope factors), and principal sites of tumor formation are listed in Table G-l ofAppendix G. Table G-2 summarizes non-carcinogenic adverse effects of constituents by listingUSEPA chronic exposure reference doses (RfD) or concentrations (RfC), the uncertainty factors,and critical adverse effects observed. The physicochemical properties and environmental fate ofconstituents are presented in Table G-3 of Appendix G.

Results of the concentration/toxicity screening for surficial soil, surface water, sediment, off-sitegroundwater and the combined groundwater data set are presented in Tables G-4 through G-7.

6.1.1.4 Summary of Constituents of ConcernThe COCs for each environmental medium as determined by the toxicity/concentration screeningprotocols are listed in Table 6-7. Toxicity values and the carcinogenic and non-carcinogeniceffects of these identified constituents of concern are listed in Table 6-8.

The on-site surficial soil was characterized by these 14 COCs: arsenic, barium, beryllium,chromium, lead, manganese, nickel, vanadium, alpha-chlordane, gamma-chlordane,benzo(a)anthracene, benzo(b)£luoranthene, benzo(a)pyrene, and phenanthrene.

The nine metal COCs present in SRI wetlands surface waters were arsenic, barium, cadmium,chromium, lead, manganese, mercury, nickel, and vanadium. Bromochloromethane, a volatile

COC, and three semi-volatile COCs, 4-cMoro-3-methylphenol, 4-methylphenol, andpentachlorophenol, were also present in SRI surface water.

The ten metal COCs present in SRI wetlands sediments were: arsenic, barium, beryllium,cadmium, chromium, lead, manganese, mercury, selenium, and vanadium. Sediment sampleanalyses indicated that 4-chloro-3-methylphenol and 4-methylphenol were semi-volatile COCsin this medium.

Ten COCs were identified for the combined groundwater data sets for the future on-site/off-siteresidential scenarios: arsenic, beryllium, chromium, lead, acetone, benzene, chloroethane, 1,1,1-trichloroethane, trichloroethene, and vinyl chloride.

6.1.2 Exposure AssessmentThis section presents an analysis of the source areas, mechanisms of release, constituents ofconcern, exposure pathways, and receptors of contamination on and in the vicinity of the SRIsite.

6.1.2.1 Source Areas Release MechanismsThree sources of contamination at the SRI site, a drum storage area and a 20,000 gallon capacitywaste oil storage tank, located in the northern part of the site in the vicinity of the barn, and adisposal cell located in the southern part of the site, were remeidated by removal of drums, liquidwastes, sludges and contaminated soil between 1984 and 1990.

SRI also employed landspreading of oily wastes over large areas of the property. This activity,in conjunction with spills of materials in the drum storage and tank area, and the migration ofcontaminants from the disposal cell to sub-surface soil and groundwater has resulted in a non-point release of contaminants to soil and groundwater at the SRI site.

This process is illustrated in the conceptual site model for the SRI site (Figure 6-1). Soil appearsto be the secondary source of contaminant releases to surface water, sediments, and on-sitegroundwater.

6.1.2.2 Identification of Exposure PathwaysIdentification of exposure pathways provides a means to estimate doses of contaminants that apopulation may receive through various activities. As defined in RAGS (USEPA, 1989a), anexposure pathway is composed of the following four elements:

• A source and mechanism of chemical release to the environment;

• An environmental transport medium for the released chemical and/or mechanism oftransfer of the chemical from one medium to another,

• A point of potential contact with humans or animals with the contaminated medium;

• A route of exposure.

An identified pathway does not imply that exposures are actually occurring, only that thepotential exists for the pathway. An environmental transport medium and exposure route notincluded in this site model is airborne transport of COCs. Neither inhalation exposure pathwaysnor airborne transport of site-related constituents to on-site or off-site receptors were consideredpertinent to SRI site. Among the four detected volatile compounds, only 2 volatile compoundswere detected in surface soils at a frequency greater than once (acetone, 8/42 and methylenechloride, 7/42), indicating that volatile organic contamination is sporadic and at relatively lowconcentrations. The maximum detected concentrations of acetone and methylene chloride insurficial soils were 0.08 and 0.05 mg/kg, respectively. Furthermore, since the vast majority(>97%) of the site is wetland, wooded area, old field, and grassland, the potential for paniculateemissions from the surface soil due to wind erosion would be negligible.

All potential exposure pathways identified under each current and future land use scenario wereevaluated in the baseline risk assessment. The exposure pathways selected under current on-siteand off-site land-use conditions and probable future on-site/off-site land use scenarios aresummarized in Tables 6-9 and 6-10 and discussed in the following sections.

6.1.2.3 Current Land Use Exposure PathwaysOn-Site Trespasser AccessThe SRI site has been abandoned for approximately 14 years and extensive remediation measuresof the site have taken place within this time period. There is no work force on-site and thecurrent on-site exposure pathways are limited to trespasser (adult, older children aged 6-12 yearsold) receptors. Older children were selected as a more conservative receptor population for thetrespasser scenarios, as this age group may explore the SRI site in this rural, sparsely populatedarea. There are no groundwater sources (e.g., active wells) on-site and groundwater was notconsidered an exposure medium for current land use scenarios for the SRI site. Constituents in

the surficial soils, wetlands sediments, and seasonal-related intermittent surface water may behazardous to on-site trespassing receptors.

Based on analysis of identified surficial soil constituents of concern, six trespasser exposurepathways were quantified in this assessment for current on-site abandoned land use:

• Incidental ingestion of site soil;• Dermal absorption of constituents from site soil;• Incidental ingestion of on-site surface water,• Dermal absorption of constituents from surface water;• Incidental ingestion of on-site sediments;• Dermal absorption of constituents from sediments.

6.13.4 Possible Future Land Use Exposure PathwaysAlthough the SRI site is presently listed as a NPL site, one possible future use of this land wouldbe to eventually build residential properties on the site. Under this possible future use scenario,it was also assumed mat the surrounding off-site property is limited to residential land use.

On-Site Residential UseExposure assessments were based on current concentrations of constituents in on-site surficialsoils, wetland sediments, surface water, and groundwater. Nine exposure pathways werequantified in this assessment for potential future residential land use of the SRI site. Five wereresidential exposure scenarios; four were related to play and recreational activities in thewoodlands/wetlands of the site. These nine exposure scenarios were as follows:

• Ingestion of groundwater (potable well water);

• Dermal contact with groundwater (bathing, household uses of tap water);

• Inhalation of volatile COCs in groundwater by bathing and showering;

• Incidental ingestion of site soil;

• Dermal contact absorption of constituents from site soil;

• Incidental ingestion of on-site surface water through recreational activities;

• Dermal absorption of COCs from surface waters through recreational activities;

EDIS/ENG/ay071494jp6 6-35SLR-0010661

Incidental ingestion of on-site sediments through recreational activities;

• Dermal contact absorption of COCs from sediments through recreational activities.

6.1.2.5 Exposure ParametersParameters specific to each exposure scenario were used in combination with the exposure pointconcentrations for each constituent of concern. A Reasonable Maximum Exposure (RME)scenario was included in each exposure pathway risk assessment. If the RME analysis indicatedpotential risk above USEPA target levels, a Central Tendency Exposure (CTE) risk analysis,employing median parameter values was presented for each exposure pathway.

Default parameter assumptions used in exposure assessments are presented in Table G-8.Physical characteristics of adult and children receptors in all exposure assessments are standarddefault values or were derived in discussions with the USEPA (1994b) about potential exposurepathways as well as frequency and duration of exposure events for the SRI risk assessment. TheRME values are largely those presented as standard default exposure factors. Average case(CTE) parameters differ from RME values in soil/sediment ingestion rates, exposure frequency,and duration for.exposures pathways.

Soil

Parameters for Incidental Ingestion of Soil/SedimentYoung children aged 1 - 6 are important receptors for the incidental soil ingestion pathway inresidential land use scenarios. An upperbound value of 200 mg/day ingestion rate was used foryoung children in residential and recreational scenarios. A value of 100 mg/day was used forolder children (6-12 years old) in the trespasser scenarios. The default parameter assumptionsused in exposure pathways by environmental media are discussed below and are presented inTables G-10 and G-l 1 for RME and CTE, respectively. Adults may ingest dust/soil indoors andduring the performance of outdoor activities such as gardening, and a default soil ingestion valueof 100 mg/day was used in all current and future residential land use scenarios. Adult trespassersingest 100 mg/day of soil when on-site. All ingested constituents are assumed to be 100%absorbed. In the CTE analysis, ingestion rates of SO mg/day for adults and older children and100 mg/day for young children were employed. Again, all ingestion constituents are assumedto be 100% absorbed.

EDIS/ENG/ay071494jp6 6-36SLR-0010662

Soil exposure frequencies of 90 and 180 days for adults and older children trespassers,respectively, are assumed in the RME risk analysis. Exposure frequencies for adults and olderchildren trespassers arc 40 and 130 days, respectively, in the CTE analysis. Exposure frequenciesare based on the assumption that older children trespass onto the SRI site daily from May toOctober.

Exposure Parameters for Contact Dermal Uptake from SoilThis pathway assumes dermal contact with soils containing measurable constituent concentrations.Quantitative estimates of the dermal uptake of constituents in dust or soil contain moreuncertainty than estimates for other routes of entry.

Contact exposures assume about 25% of the body surface area in contact with the medium. Thisincludes the head, hands, forearms, and lower legs. The parameters for estimating the absorbeddermal dose from contact with soils are listed in Tables G-12 and G-13. The contact dermalexposure equation term for soil-skin adherence factor is 1.0 mg/cm2 for RME and 0.2 mg/cm2

for CTE exposure analyses. Absorption factors of 6% and 1% were employed for PCBs, andcadmium, respectively. Soil-dermal contact absorption factors are not available for other COCs.

Groundwater

Exposure Parameters for Ingestion of GroundwaterThe groundwater ingestion scenario assumes an individual (child or adult) drinks only tap waterand beverages made from tap water at his/her residence. Ingestion rates are two liters per dayfor adults and one liter a day for children. Groundwater COCs are assumed to be completely(100%) absorbed from the gastrointestinal tract (Tables G-14 and G-15).

Exposure Parameters for Dermal Contact with GroundwaterThese exposure pathway calculations assume daily total body contact with residential water whichtakes into account all facets of use including bathing and showering, hand-washing, laundering,and other domestic uses of tap water. In dermal uptake exposure assessment of COCs, apermeability coefficient (Kp) is used to estimate diffusion of the chemical through the skin(Table G-3). If not available, a permeability coefficient was estimated by an equation for organiccompounds, or if the COC is an inorganic, the default K,, value of l.OE-03 cm/hr was used(USEPA, 1992b). Tables G-9, G-16, and G-17 show standard default parameters for thisexposure assessment.

EDIS/ENG/ay071494.rp6 6-37SLR-0010663

Parameters for Inhalation of Volatile Groundwater ConstituentsThis potential pathway for exposure to volatile constituents in groundwater assumes inhalationthrough volatilization of constituents from groundwater. This is most likely to occur duringbathing and/or showering. Under this simplified exposure assessment scenario (Tables G-18 andG-19), it is assumed that all (100%) of the volatile constituents in the hot water are convertedto vapor in a bathroom of a given size. It is also assumed that pulmonary retention (i.e.,absorption) is 100% of all inspired airborne emissions.

Surface Water and Sediments

Trespasser and Recreational Activities Exposure PathwaysSite-related constituents were detected in surface water and sediment samples collected from theSRI site. It is noted that these on-site wetlands are only seasonally inundated; there are nopermanent bodies of standing water on the SRI site.

Two exposure pathways, incidental dermal contact and ingestion, were evaluated for both mediain trespasser scenarios and residential recreational activities, such as play or hiking. Defaultsparameters for these exposure assessments are presented in Tables G-20 through G-27.

6.1.2.6 Summary of Exposure AssessmentThe exposure assessment evaluates a given population's chronic daily intake of each selectedconstituent of concern identified in samples taken from the SRI site. Exposure pathways wereassumed for the SRI site under current land use and future land use scenarios. The quantifiedpathways under current land-use conditions are as follows:

On-Site Trespasser Access• Incidental ingestion of site soils

• Dermal absorption of constituents from site soil

Incidental ingestion of on-site surface water

• Dermal absorption of constituents from surface water

• Incidental ingestion of on-site sediments

• Dermal Absorption of constituents from sediments

EDIS/ENG/ay071494.rp6 6-38SLR-0010664

The quantified exposure pathways under the future on-site/off-site land-use conditions are asfollows:

On-Site/Off-Site Residential Use• Ingestion of groundwater (potable well water)

• Dermal contact with groundwater (bathing, household uses of tap water)

• Inhalation of groundwater-derived volatile constituents (through showering andbathing)

• Incidental ingestion of site soils

• Dermal absorption of constituents from site soil

• Incidental ingestion of on-site surface water through recreational activities

• Dermal absorption of constituents from surface water through recreational activities

• Incidental ingestion of on-site sediments through recreational activities

• Dermal absorption of constituents from sediments through recreational activities.

Exposure parameters specific to each exposure scenario were used in combination with theexposure point concentrations for each constituent of concern. A reasonable maximum exposure(RME) is included, and if that RME analysis indicates potential risk above EPA target levels,an average scenario (Central Tendency Exposure) is analyzed for each relevant exposure pathway.

6.1.3 Toxlcfty AssessmentThe toxicity assessment weighs the available evidence of the potential for constituents to causeadverse effects in exposed individuals (receptors) and provide, where possible, as estimate of therelationship between the extent of exposure to a constituent and the increased likelihood and/orseverity of adverse effects.

Two broad categories of chemically-induced disease states are evaluated in the toxicityassessment of each identified constituent, carcinogenic effects and non-carcinogenic effects. Asexposure assessment attempts to define the chronic lifetime dosage of COCs received by anindividual in a given scenario, toxicity assessment attempts to link adverse effects associated withexposure to the particular COC. The linking of exposure to a constituent with possible adverse

EDIS/ENG/ay071494.rp6 6-39SLR-0010665

effects is the major tenet of toxicology; the dose received determines the magnitude of adverseeffects related to the constituent's inherent toxicity.

Fundamental concepts of toxicity assessment and the algorithms used to express risks associatedwith exposure to COCs are presented in the following sub-sections. The concept of toxicityvalues for quantifying carcinogenic and non-carcinogenic effects is introduced to show theimportance of these parameters in risk characterization. An assessment of COCs for carcinogeniceffects is described by discussion of USEPA's weight-of-evidence carcinogen classificationscheme and the utilization of cancer potency slope factors. Toxicity assessment of COCs fornon-carcinogenic effects takes a different approach, using the ratio of the estimated dose to aconstituent-specific reference dose to characterize the hazard potential for such adverse effects.Toxicity profiles for each of the COCs is presented in Appendix H. These summaries brieflydescribe the absorption, metabolism, mode of action, and significant toxic effects observed inexperimental animal studies or in human investigations.

Exposure assessment establishes a conservative daily intake of the constituent by all relevantpathways of exposure, and the toxicity assessment uses USEPA toxicity values to characterizethe dose-response relationship of adverse effects. The two main toxicity values used to expressa constituents's dose-response relationship is a slope factor for carcinogenic effects and referencedose or reference concentration for non-carcinogenic effects.

The slope factor (SF) is a plausible upper-bound estimate of the probability of a carcinogenicresponse per unit intake of a chemical over a lifetime. The slope factor is used in riskassessments to estimate an upper-bound lifetime probability of an individual developing canceras a result of exposure to a particular level of a potential carcinogen.

Chronic reference doses (RfD) or concentrations (RfC) are estimates, with uncertainty spanningperhaps an order of magnitude or greater, of a daily exposure level for the human population,including sensitive subpopulations, that is likely to occur without an appreciable risk ofdeleterious effects during a lifetime. Chronic RfD or RfC values are specifically developed tobe protective for long-term exposure to a constituent.

In general, SF and RfD or RfC values are based on long-term animal studies and expressed inthe units of mg/kg-day. For a few constituents, however, adequate human data are available andare used.

EDIS/ENG/ay071494jp6 6-40SLR-0010666

6.1.3.1 Toxicity Assessment for Carcinogenic EffectsFor carcinogens, risks are estimated as the incremental probability of an individual developingcancer over a lifetime as a result of exposure to the potential carcinogen. In carcinogenassessment the USEPA evaluates the available data to determine the likelihood that an agent isa human carcinogen. Based on the extent to which a constituent has been shown to be acarcinogen in animal studies, in humans, or in both, the agent is given a provisional weight-of-evidence classification. USEPA's current classification of the overall weight of evidence has thefollowing five categories:

Class A Human Carcinogen - Sufficient evidence from epidemiological studiessubstantiated by causal association between exposure and carcinogenicity.

Class B1 Probable Human Carcinogen - Limited evidence of carcinogenicity in humansfrom available epidemiological data.

Class B2 Probable Human Carcinogen - Sufficient evidence of carcinogenicity inanimals, but inadequate or no evidence in humans.

Class C Possible Human Carcinogen - Limited evidence of carcinogenicity in animals.

Class D Not Classified - Inadequate evidence of carcinogenicity in animals to supportclassification.

Class E Not a Human Carcinogen - No evidence of carcinogenicity in at least twoadequate animal tests in different species or in both epidemiological andanimal studies.

Based on the evidence that a constituent is a known or probable human carcinogen, a toxicityvalue that defines a quantitative relationship between dose and response (i.e., slope factor) iscalculated by the USEPA. A slope factor (SF) converts estimated daily intakes averaged overa lifetime of exposure directly to incremental risk of an individual developing cancer. Becauserelatively low intakes, compared to those received by test animals, are more comparable toenvironmental exposures, a critical assumption is that the dose-response relationship will be linearin the low-dose portion of the multistage model dose-response curve. Under this assumption, theslope factor is a constant and risk win be directly related to intake. Thus, the linear form of thecarcinogenic risk equation is usually applicable for estimating site risks. This linear low-doseequation is defined as:

EDIS/ENG/ay071494.rp6 6-41SLR-0010667

Risk = GDI x SF

where:

Risk = a unitless probability (e.g., 1 x 10"6) of an individual developing cancer overa lifetime

GDI = chronic daily intake averaged over 70 years (mg/kg-day)SF = slope factor, expressed in (mg/kg-day) '

The aggregate carcinogenic risk from exposure to several constituents is calculated by summationof the individual cancer risks for each constituent in the media identified in each appropriateexposure pathway assessment and then summing the total carcinogen risk for all relevantexposure pathways.

where:

the total cancer risk, expressed as a unitless probability;the risk estimate for the i* constituent in the j* exposure medium pathway.

The resultant summation of constituent-specific cancer risks is a very conservative upper boundestimate of cancer risk for the following reason. Each SF is an upper 95th percentile estimateof potency and because percentiles of probability distributions are not strictly additive, the totalcancer risk estimate becomes more conservative as the number of cancer risk estimates aresummed. Regardless, this method is used to ensure that carcinogenic risks will not beunderestimated.

6. 1.3.2 Toxicity Assessment of Non-Carcinogenic EffectsFor non-carcinogenic constituents, the measure used to describe the potential for non-carcinogenicchronic toxicity to occur in an individual is evaluated by comparing the estimated exposure levelover a specified time period with the appropriate non-carcinogenic toxicity value (i.e., RfD orRfC). This ratio of exposure to toxicity is called a non-carcinogenic hazard quotient:

EDIS/ENG/ay071494jp6 6-42SLR-0010668

CD/Non-Cancinogemc Hazard Quotient = ——

where:

GDI = Chronic daily intake (mg/kg-day)RfD = Reference dose

The non-carcinogenic hazard quotient assumes mat mere is a level of exposure (e.g., RfD or RfC)below which it is unlikely for even sensitive subpopulations to experience adverse health effects.

For assessing the health impacts of several non-carcinogenic constituents, reference doses orconcentrations are compared to exposure-specific intake rates of each constituent of concern. Asummation of these hazard quotients is termed the hazard index (HI). If the hazard indexexceeds unity (i.e. >1.0), there may be concern for potential non-carcinogenic effects.

The aggregate HI is expressed as:

Hazard Mdexr

where:

Hip = Total Hazard Index for an individual in any land use scenariok = k* exposure pathway

j = Hazard quotient for the i* constituent in the j* exposure medium

If this ratio of the chronic daily intake to the reference dose or concentration exceeds 1.0 (unity)for the defined exposure scenario, this provides an indication that the exposed receptor may besubject to an adverse impact. If the ratio is below unity, then it is generally assumed that noadverse impact to human health will occur.

The Hazard Index approach does have limitations and should be interpreted carefully based onthe known aspects of additive toxic effects from exposure to mixtures of chemicals. First,because the Hazard Index is a ratio, after unity has been exceeded, the magnitude of the indexhas little bearing on the potential severity of adverse effects that may be anticipated. Forexample, a HI of 5 does not indicate the non-cancer hazard is greater than a HI of 3. Secondly,as pointed out by the USEPA's Science Advisory Board (USEPA, 1993b) it is inappropriate to

EDIS/ENG/ay071494.rp6 6-43SLR-0010669

sum non-cancer hazard quotients for constituents that do not have similar toxic modes of actionor that do not affect the same organ system.

Current USEPA guidance recommends that action is generally warranted at a site when thecumulative carcinogenic risk is greater than l.OE-04 to l.OE-06 or the cumulative non-carcinogenic hazard index is greater than 1.0. Thus, when the human health risk assessment,based on RME assumptions, indicates that the cumulative risk associated with a medium isgreater than l.OE-04 or that the hazard index is greater than 1.0, that medium presents a potentialconcern.

6.1.3.3 Toxlclty Profiles for the Constituents of ConcernFrom the toxicity/concentration screening protocol used for identifying site-related COCs, thirteenmetals, two pesticides and PCBs and fifteen organic constituents were identified as theconstituents of concern that would drive die human health risk assessment of the SRI site. Atoxicity profile is developed below for each constituent and summarizes important informationregarding constituent uptake by various routes of exposure, its metabolism and elimination,toxicity information, and target organs. Toxicity profiles for all COCs are found in AppendixH. This summaries emphasize chronic exposure and potential disease states associated withchronic low dose exposure, including cancer.

6.1.3.4 Toxlclty Assessment SummaryThe toxicity assessment component of die human health risk assessment is based on the use ofUSEPA-derived toxicity values. As specified in RAGS (USEPA, 1989a), the resource hierarchyfor selection of the most current and appropriate toxicity values are, in descending order:

• IRIS (Integrated Risk Information System), an on-line database maintained by USEPA

• HEAST (Health Effects Assessment Summary Tables), published annually by theUSEPA

• ECAO (Environmental Criteria and Assessment Office) guidance documents, generaltoxicology information, extrapolations, and guidance for constituents without toxicityvalues.

Using the IRIS slope factor for benzo(a)pyrene as the reference toxicity value, cancer slopefactors for other Class B PAH carcinogens were developed from the order-of-magnitude potencyestimates for toxic equivalent factors of PAHs (USEPA, 1993). Toxicity values for the identifiedCOCs are listed in Table 6-8. The state-of-the-science of toxicology and epidemiology is such

EDIS/ENG/ay071494jp6 6-44SLR-0010670

that there are many sources of uncertainty associated with the use of assigned toxicity values todetermine carcinogenic risks and hazard assessment of non-cancer adverse effects of aconstituent.

6.1.4 Risk CharacterizationThe risk characterization combines the information presented in Section 6.1.2 (ExposureAssessment) with the information presented in Section 6.1.3 (Toxicity Assessment) to describethe type and magnitude of potential carcinogenic risks and non-carcinogenic hazards .due toexposure to contaminants originating at the SRI site. The magnitude and types of risks dependon the nature, duration, and frequency of exposure to constituents of concern, and thecharacteristics of the exposed populations. Potential exposures in this assessment are separatedinto two general categories. Current land use describes the potential exposure routes thatcurrently exist to on- and off-site if no remedial action was taken. Future land use describes thepotential exposure routes that may exist at some time in the future if the SRI site was developedresidentially and no remedial action was taken. Calculated health-related risks are further dividedinto carcinogenic risks and non-carcinogenic hazards.

6.1.4.1 Current Land UseThe SRI site is an abandoned 210-acre site in a rural and sparsely populated area. Thecarcinogenic risks and non-carcinogenic hazards associated with the current land use of the SRIsite and the surrounding area are summarized and discussed in the following subsections.

Carcinogenic Risk CharacterizationAs described in Section 6.1.3.1, carcinogenic risks are expressed as the probability of anindividual developing a career over a lifetime. These risks were calculated by multiplying thechronic daily intake (GDI) of an individual constituent of concern by the slope factor (SF)associated with that particular constituent to yield constituent-specific risks for each pathway ofinterest These individual constituent-specific risks were then summed to yield a total risk foreach exposure pathway. The following sections summarize the total carcinogenic risks to thereceptor populations based on current land usage.

On-Stte Trespasser Scenarios:

Ingestion of On-Site SoilThe SRI site has been abandoned and no work force is presently on site. However, trespassersmay ingest incidentally small quantities of on-site soil. Carcinogenic risk estimates for incidental

EDIS/ENG/ay071494jp6 6-45SLR-0010671

soil ingestion by on-site trespassers is presented in Table G-28. Under reasonable maximumexposure conditions, calculations for incidental ingestion of on-site soil estimated a carcinogenicrisk of 2.51E-06 for adults and 2.51E-06 for older children (ages 6-12 years) trespassers. Arsenicwas the major contributor to carcinogenic risk from ingestion of on-site soils.

Dermal Contact from On-She SoilTrespassers at the SRI site may absorb constituents of concern from surficial soils through directsoil contact with their skin. However, because no USEPA soil-to-skin absorptions factors for soilCOCs are available, carcinogenic rides were not qualified for this exposure pathway.

Ingestion of Surface WaterSurface runoff from the SRI site and groundwater infiltration may result in site-relatedconstituents of concern in the surface waters. Trespassers may ingest small amounts of surfacewater. The total carcinogenic risk to adults and older children due to incidental ingestion ofsurface water during trespassing activities was 5.26E-07 and 4.21E-07, respectively. Themajority of this risk is due to arsenic in the surface water (Table G-30).

Dermal Contact from Surface Water (Recreational)Dennal absorption of site-related constituents of concern in the surface water may occur as aresult of trespasser activities. The total carcinogenic risk to adults and older children from dermalabsorption of constituents of concern in surface water was 8.55E-06 and 6.45E-06, respectively.The majority of this risk was due to pentachlorophenol in the surface water (Table G-31).

Ingestion of SedimentSite-related constituents of concern may become sequestered in the SRI wetlands sediment fromsurficial runoff and groundwater infiltration. Incidental ingestion of these wetlands sediment mayoccur during trespasser activities. The carcinogenic risk from incidental ingestion of sedimentwas 2.78E-06 for both adult and older children trespassers. Arsenic in the sediment contributes95% of the cancer risk from this pathway (Table G-32).

Dermal Contact to SedimentNo carcinogenic risks were calculated for the dermal contact exposure with wetlands sedimentsbecause either dermal absorption factors or slope factors are not available for metals in sediments(Table G-33).

EDIS/ENG/ay071494.rp6 6-46SLR-0010672

Non-Carcinogenic Hazard CharacterizationAs described in Section 6.1.3.2, non-carcinogenic hazards are expressed as hazard quotients. Ahazard quotient is derived for a given constituent of concern by comparing an exposure level overa specified time interval to a reference dose or concentration derived for a similar exposureperiod. Hazard quotients were calculated for each constituent of concern for each exposurepathway of interest. These individual constituent-specific hazard quotients were then summedto yield a total hazard quotient for each exposure pathway. The following sections summarizethe total noncarcinogenic hazards to receptor populations based on current land usage. .

On-Site Trespasser Scenarios-.

Ingestion of SoilTrespassers at the SRI site may ingest small quantities of soil. Incidental ingestion of on-site soilwas calculated, producing non-carcinogenic hazards of 1.21E-02 and 4.85E-02, for adults andolder children, respectively (Table G-34).

Dermal Contact with SoilTrespassers at the SRI site may absorb constituents of concern from surficial soils through theirskin. Non-carcinogenic hazard by soil dermal absorption to trespassers was not calculated(Table G-3S) because dermal absorption factors are not available for the COCs.

Ingestion of Surface WaterThe total non-carcinogenic hazard to adult and older children trespassers due to incidentalingestion of surface water was 6.7IE-03 and 2.68E-02, respectively (Table G-36). The majorityof this hazard was contributed by manganese in SRI site surface water.

Dermal Contact to Surface WaterThe total non-carcinogenic hazard to adult and older children trespassers from dermal absorptionof constituents of concern in surface water is 6.28E-03 and 2.37E-02, respectively (Table G-37).Pentachlorophenol was the major contributor to non-cancer hazard in surface waters.

Ingestion of SedimentSite-related constituents of concern may become sequestered in the wetland sediments fromsurficial runoff and subsequent deposition. The non-carcinogenic hazard from incidentalingestion of sediment is 2.23E-02 and 8.92E-02 for adults and children, respectively (Table G-38). Arsenic was the major contributor to the non-cancer health hazard of this sediment pathway.

EDIS/ENG/ay071494jp6 6-47SLR-0010673

Dermal Contact with SedimentThe calculated non-carcinogenic hazard for deimal absorption of cadmium from sediments was1.60E-04 and 6.02E-04 for adult and older children trespassers, respectively (Table G-39).Cadmium was the only COC in sediment that has a defined soil-to-skin absorption factor.

6.1.4.2 Future Residential Land UseThe future use of the SRI site is most probably applicable for use as agricultural lands.However, in order to provide a conservative assessment of the potential risks and/or hazardsposed by constituents at the SRI site, a residential land use scenario was selected. Severaldifferences are noted between the cunent land use scenarios and future land use scenarios andthese are reflected in both environmental media and receptor populations. In the future usescenarios, on-site soil constituent concentrations are used for the hypothetical on-site residentialexposure scenarios. In the future residential use scenarios, wetlands surface water and sedimentCOCs are examined for risk/hazards to adults and children under recreational use exposurescenarios.

Furthermore, in accordance with USEPA Region n, the groundwater data sets collected in theSRI remedial investigation, (on-site groundwater and off-site residential well water data sets),were combined to establish a hypothetical single groundwater aquifer. This theoreticalgroundwater source was used to estimate future off-site/on-site carcinogenic risk and non-carcinogenic hazards for residential use of groundwater. The following sections present thecarcinogenic risks and non-carcinogenic hazards associated with this hypothetical residential landuse scenario.

Carcinogenic Risk CharacterizationCarcinogenic risks were characterized for future land use in the identical manner as they werefor current land use with the exceptions noted above regarding changes in the receptor populationand a different groundwater data set for the future use scenarios.

Ingestion of Soil:Hypothetical future residents of the SRI site may ingest soil during regular daily activities suchas playing and gardening. The carcinogenic risk from ingestion of on-site soil by residents wascalculated to be 1.22E-05 and 2.28E-05 for adults and young children, respectively (Table G-40).The majority of the total risk from mis pathway is attributable to arsenic.

EDIS/ENG/ay071494jp6 6-48SLR-0010674

Dermal Contact with Soil:Individuals (adults and children) living at the site could be exposed to site-related constituentsof concern through dermal absorption during normal daily activities. The carcinogenic risk toresidential adults and children from dermal absorption of constituents in the soil at the SRI sitewas not calculated (Table G-41). Quantitative risk analysis was limited because there are no soil-to-skin absorption factors for soil COCs.

Incidental Ingestion of Surface Water:The exposure pathways for wetlands surface water and their associated carcinogenic risks werecalculated for both adults and young children using recreational exposure scenarios to establishcarcinogenic risk. The total carcinogenic risk to adults and youg children due to incidentalingestion of surface water during recreational play activities was 5.26E-07 and 9.82E-07,respectively. The majority of this risk was due to arsenic in the surface water (Table G-42).

Dermal Contact with Surface Water:Dermal absorption of site-related constituents of concern in the surface water may occur as aresult of recreational activities. The carcinogenic risk to adults and younger children from dermalabsorption of constituents of concern in surface water was 8.55E-06 and 9.47E-06, respectively.The majority of this risk was due to pentachlorophenol in the surface water (Table G-43).

Incidental Ingestion of Sediment:Site-related constituents of concern may become sequestered in the SRI wetlands sediment fromsurficial runoff and groundwater infiltration. Incidental ingestion of these wetlands sediment mayoccur during play and other recreational activities. The carcinogenic risk from incidentalingestion of sediment is 3.48E-06 and 1.30E-05 for adult and young children, respectively.Arsenic in the sediment contributed 95% of the cancer risk from this pathway (Table G-44).

Dermal Contact of Sediment:No carcinogenic risks are calculated for the dermal contact exposure with wetlands sedimentsbecause either dermal absorption factors or slope factors are not available for the potential metalcarcinogens in sediments (Table G-45).

Ingestion of Groundwater:As stated previously, a hypothetical single groundwater aquifer was used to estimate future off-site/on-site cancer risk from residential use of groundwater. Based on the hypothetical futureland use scenario of residential development of the SRI site, ingestion of the pooled area

EDIS/ENQ/ay071494.ip6 6-49SLR-0010675

groundwater has been calculated to produce a total RME carcinogenic risk of 2.07E-04 and9.65E-05 for adults and children, respectively (Table G-46). The majority of the cancer risk fromthis pathway was attributable to arsenic in this hypothetical aquifer.

When this pathway was evaluated by CTE analysis, carcinogenic risk was reduced for adults to6.20E-05 but the risk to children remained the same at 9.65E-05 (Table G-58 and Table G-13).

Dermal Contact to Groundwater:Residential use of the on-site/off-site groundwater by the hypothetical on-site resident wouldresult in dermal absorption of constituents of concern. The total calculated carcinogenic riskfrom dermal absorption of constituents in the groundwater was 1.02E-06 for adults and 3.46E-07for children (Table G-47).

Inhalation of VOCs in Groundwater:Hypothetical on-site residential populations may be exposed to site-related constituents of concernthrough inhalation of volatile constituents present in the groundwater. These volatile constituentswill be available via inhalation during bathing and showering activities. The carcinogenic riskfrom inhalation of volatile constituents of concern in the overburden groundwater has beencalculated to be 1.88E-06 and 1.75E-06 for adults and children, respectively (Table G-48).

Non-Carcinogenic Hazard CharacterizationHazard quotients were calculated for each constituent of concern for each exposure pathway ofinterest in the hypothetical future land use scenario. These individual constituent-specific hazardquotients were then summed to yield a total hazard quotient for each exposure pathway. Thefollowing sections summarize the total noncarcinogcnic hazards to receptor populations based onhypothetical future land usage.

Ingestion of Soil:The total non-carcinogenic hazard from ingestion of on-site soil by residents was calculated tobe 4.71E-02 and 4.40E-01 for adults and children, respectively (Table G-49). Arsenic was themajor contributor to non-carcinogenic hazard.

Dermal Contact with Soil:The total non-carcinogenic hazard to residential adults and children from dermal absorption ofconstituents in the soil at the SRI site was not calculated (Table G-50). Soil-dermal contactabsorption factors are not available for soil COCs.

EDIS/ENG/ay071494jp6 6-50SLR-0010676

Ingestion of Surface Water:The total non-carcinogenic hazard to adult and children due to incidental ingestion of surfacewater during recreation and play activities was 6.7 IE-03 and 6.26E-02, respectively (Table G-51).Arsenic and manganese were the major contributors to non-carcinogenic hazards of SRI sitesurface water.

Dermal Contact to Surface Water:The total non-carcinogenic hazard to adult and young children from dermal absorption ofconstituents of concern in surface water during play activities was 6.28E-03 and 3.48E-02,respectively (Table G-52). Pentachlorophenol was the major contributor to non-cancer hazardthrough dermal contact to surface waters.

Ingestion of Sediment:Site-related constituents of concern may become sequestered in the wetland sediments fromsurficial runoff and subsequent deposition. The non-carcinogenic hazard from incidentalingestion of sediment was 2.23E-02 and 4.16E-01 for adults and children, respectively (TableG-53). Arsenic in the sediment contributed 67% of the total hazard from this pathway.

Dermal Contact with Sediment:The calculated non-carcinogenic hazard for dermal absorption of cadmium from sediments is1.60E-04 and 8.83E-04 for adult and young children, respectively (Table G-54). Cadmium wasthe only COC in sediment that has a definitive sediment-to-skin dermal absorption factor.

Ingestion of Groundwater:Based on the hypothetical future land use scenario of residential development of the SRI site, theconceptual pooled groundwater data set aquifer could be used as a potable water source for on-site and off-site receptors. Ingestion of this groundwater has been calculated to produce a non-carcinogenic hazard of 5.76E+02 and 1.34E+03 for adults and children, respectively (TableG-SS). The majority of the total risk (93%) from this pathway was attributable to acetone in thehypothetical aquifer. CTE analysis of mis pathway did not change the non-carcinogenic hazardsto residential receptors (Table G-59).

Dermal Contact to Groundwater:The calculated non-carcinogenic hazard from dermal absorption of constituents in thegroundwater is 2.33E+00 for adults and 3.97E-KX) for children (Table G-56). Acetone in thehypothetical aquifer contributed the largest percentage of the total pathway health hazard. CTE

EDIS/ENG/ay071494.rp6 6_51SLR-0010677

analysis did not lower non-carcinogenic hazards to residential receptors by this pathway (TableG-60 and Table 6-13).

Inhalation of VOCs in Groundwater:The non-carcinogenic hazard from inhalation of volatile constituents of concern in thegroundwater was not calculated because no RfC values are available for the COCs (Table G-57).

6.1.4.3 Cumulative Risks/Hazards to Potentially Exposed PopulationsFor this risk assessment, it was assumed that die same individual or subpopulation may beexposed to the constituents of concern via multiple pathways. Accordingly, the carcinogenicrisks and the non-carcinogenic hazards calculated in the previous sections are summed to providean estimation of the total risk/hazard to the exposed populations from site-related constituents ofconcern from the SRI site. Reasonable maximum exposure (RME) default parameters wereemployed for all potential pathways to represent the most conservative estimate of potentialexposure and therefore, be the most health protective.

For any pathway that showed excessive risk/hazard using RME exposure parameters, thesepathways were re-evaluated using Central Tendency Analysis exposure parameters. CentralTendency Exposure (CTE) default parameters utilize average exposure frequencies and durationvalues rather than upperbound estimates for determining daily chronic intake of constituents inthe risk/hazard analyses. Tables G-58 to G-60 are CTE carcinogenic risk analyses and non-carcinogenic hazard indices for exposure pathways than indicated excessive risk/hazard underRME exposure scenarios.

Current Land UseThe total carcinogenic risk to on-site trespasser from exposure to site-related constituents ofconcern is 1.44E-05 for adults and 1.22E-05 for older children (Table 6-11). Figure 6-2demonstrates that dermal contact with on-site surface water contributed 63% of the totalcarcinogenic risk to trespassers. Pentachlorophenol contributed 94% of total risk to current on-site land use conditions.

The total non-carcinogenic hazard to on-site trespasser from exposure to constituents of concernis 4.76E-02 for adults and 1.89E-01 for older children (Table 6-11). As shown in Figure 6-3,incidental ingestion of wetlands sediment contributed 47% of the total non-carcinogenic hazard,with arsenic contributing 99% of the non-carcinogenic risk of this medium.

Figures 6-4 and 6-5 are bar graph charts for current land use that show cancer risk and non-carcinogenic hazard contribution for each media-specific exposure pathway to on-site trespassers.

Future Land UseThe total carcinogenic risk to residential adults and young children based on future on-siteresidential exposures has been calculated to be 2.34E-04 and 1.45E-04, respectively (Table 6-12).As illustrated in Figure 6-6, groundwater is accountable for 89% of the carcinogenic risks tofuture on-site residential populations. Arsenic was the major contributor to this calculatedcarcinogenic risk. The bar chart graph (Figure 6-8) indicated groundwater ingestion was inexceedence of USEPA's risk guidance.

In the future land use scenario, the total non-carcinogenic hazard to adults and children in an on-site residential setting has been calculated to be 5.78E+02 and 1.34E+03, respectively (Table6-12). Figure 6-7 shows that 99.9% of the non-carcinogenic hazard is attributed to use ofgroundwater from the composited groundwater aquifer. Acetone was the principal COC andaccounts for 99% of the non-carcinogenic hazard of this groundwater.

Figure 6-9 shows non-carcinogenic hazards for each media-specific pathway for this future landuse residential scenario. Ingestion of groundwater and dermal contact with groundwater werepathways that indicated excessive hazard All other pathways for both children and adults hadhazard indices of less than unity.

6.1.4.4 Summary of Risk CharacterizationQuantitative characterization of the carcinogenic risks and non-carcinogenic hazards has beenperformed based on current land use and potential future land use scenarios. Carcinogenic risksare expressed as the increased probability of an individual developing cancer over a lifetime, andnon-carcinogenic hazards are expressed as hazard quotients of exposure levels over referencedoses or concentrations.

Current Land UseThere is no current land usage of the SRI site at present and as such, trespassers are the onlyreceptors to on-site constituents. On-site environmental media of concern include soil, wetlandssurface water, and sediments. The total carcinogenic risk to adult trespassers on-site has beencalculated to be 1.44E-05, which is mostly attributable to dermal contact with surface watercontaining pentachlorophenol. Pentachlorophenol was detected in only one sample of the 18surface water samples collected.

The total non-carcinogenic hazard to on-site adult trespassers has been calculated at 4.76E-02.Incidental ingestion of on-site wetlands sediments contributes more than 60% of the total non-carcinogenic hazard. Arsenic in the sediments contributes the greatest percentage of the totalcumulative non-carcinogenic hazard. Arsenic was detected in all sediment samples collected atthe site and the detected concentrations were consistently high for all of the samples. Surfacewater COCs contributed about 27% of the non-carcinogenic hazard to current land usetrespassers. Pentachlorophenol was the driving COC for this media. Again, pentachlorophenolwas only detected in 1 of 18 surface water samples collected on-site, suggesting this constituentis found infrequently in this medium.

Future Land UseThe pathway that contributes the greatest percentage to the total risk is ingestion of groundwater.Under the future land use scenario, the hypothetical on-site resident (both adult and child) wouldbe presented with unacceptable carcinogenic risks from all of the groundwater pathways(ingestion, dermal absorption, and inhalation). The carcinogenic risk of the compositedgroundwater data set is attributed primarily to arsenic. However, this COC was detected at afrequency of 17.6%.

Acetone in the composited groundwater data set contributes the greatest percentage of the totalnon-carcinogenic hazard and was detected in approximately 34% of the groundwater samplesmaking up this data set.

6.7.5 Uncertainty Analysis6.1.5.1 Analytical Data and Identification of COCsUncertainty in a human health risk assessment relates to both variability of the available data andto the uncertainty related to lack of knowledge of the true value for certain parameters of interest.Acquisition of additional data will typically reduce uncertainty but will not affect variability.

EDIS/ENG/ay071494jp6 6-65

The analytical data sets for the environmental media collected from the SRI site providedsufficient number of samples and are adequate for conducting a baseline human health riskassessment. The quality of the data is also adequate for risk analyses. Strict validationprocedures were employed using independent auditors for data review. There is high confidencein all data sets used, particularly for constituents present in elevated concentrations, as the95% UCL value is used for constituent concentrations in all exposure scenarios in developing diereasonable maximum exposure (RME) chronic daily intake of COCs in all environmental media.

6.1.53 Exposure AssessmentGeneral uncertainties related to the conservativeness of the risk analysis process andmethodologies are especially apparent in the exposure assessment. The USEPA paradigm forconducting human health risk assessments presently requires the use of point estimates for allparameters of interest (e.g., constituent concentration, cancer potency slope factor, body weight,length of residence) to establish risk estimates for exposure scenarios. Furthermore, the inherentconservatism in the upper-bound point estimate approach is an attempt to account for bothvariability and uncertainty with the use of conservative assumptions.

As single point estimates do not provide a vehicle for conveying the heterogeneity or variabilityof the data, no associated measure of confidence can be provided as a means of examiningexposure assessment or the completed risk analysis. Therefore, uncertainty analysis is generallylimited to qualitative statements about the confidence placed in critical data or default inputparameters used in exposure assessment component used to build the human health riskassessment.

Exposure PathwaysUsing standard USEPA default values for ingestion rates of environmental media, exposureduration and frequency of events, most of the scenarios probably overestimate the level ofexposure in the interest of standardization and conservatism. As examples, the average personprobably does not ingest 2 liters of water every day of his or her life, ingest 100 or 200 mg ofsoil daily or remain in a residence 24 hours a day for 30 years.

In addition to the frequency and duration of exposure events, the fraction of COCs actuallyabsorbed with oral or dermal exposure is the primary factor in determining the chronic dailyintake (GDI) dose of COCs. Few data are available that quantify oral and dermal uptake ofCOCs by humans. In these exposure assessments, it is assumed that 100% of the ingested COCsare absorbed. This assumption is probably valid for organic, lipophilic COCs but greatly

EDIS/ENG/ay071494jp6 6-66SLR-0010692

overestimates the metals intake. Many animal (and limited human) oral availability studiesindicate that less than 10% of most metals, even in soluble form, are absorbed from thealimentary tract into the body.

Dermal uptake of COCs by direct dermal contact to soil, sediment, or water is also an exposureparameter with inherent uncertainty. Dermal absorption coefficients for estimating absorbeddoses from direct skin contact with water are available or can be calculated (USEPA, 1992a), andthese estimated parameters were used for uptake of COCs from water in direct contact with skin.Dermal uptake of COCs by skin in direct contact with COCs adsorbed on soil/sediment is moreuncertain. Because of the dearth of published soil-to-skin absorption factors, soil/sedimentdermal absorption calculations were only available for PCBs and cadmium. Dermal uptake oforganic, lipophilic COCs from soil is probably underestimated in this risk assessment.

Site-Specific UncertaintiesIncidental ingestion and direct dermal contact with soil, surface water and sediments areestimated and considered complete pathways for trespasser exposure. However, the fact that themajority of the on-site surficial soil is covered by a grassy vegetation is not taken into account,and it is understood that this environmental medium pathway overestimates contact with on-sitesoil. In addition, the SRI site is located in tipper New York state. This area of the country oftenexperiences harsh winter conditions and it would not be uncommon for the SRI site to be frozenand snow-covered for up to 6 months a year.

6.1.5.3 Toxicity AssessmentToxicity assessment relies upon the use of toxicity values (cancer potency slope factors, non-carcinogen reference doses) developed by the USEPA to quantitate chronic toxicity of theconstituents of concern. These toxicity values may be estimated from human data but the processis largely dependent upon laboratory animal data generated from a variety of toxicology andsafety testing studies conducted on constituents. More often than not, these original toxicologystudies were not designed to support risk assessment assumptions. Rather, these studies weredesigned to answer specific questions about constituents' adverse effects at specified, and usuallyhigh doses, or to answer specific questions about a constituent's disposition after administration.

Toxicity values are not available for all constituents of concern; therefore risks/hazards cannotbe quantitatively characterized for these constituents and the total cumulative risk/hazard for thesite may be underestimated in such circumstances.

EDIS/ENG/ay071494jp6 6-67SLR-0010693

Carcinogen Toxicity ValuesThe carcinogen toxicity values, slope factors (SF), are derived from cancer bioassay orepidemiologic dose-response data that have been transformed using linear models to estimatecarcinogenic risk at constituent concentrations mat may be several orders of magnitude lower thatthe given dose or estimated exposure concentration. There are a number of uncertaintiesassociated with this methodology including the following concerns:

• The extrapolation of carcinogenic effects observed at the high doses necessary to conductanimal cancer studies to possible cancer effects at substantially lower doses is based onthe hypothesis that there is no threshold dose for carcinogens. No experimental evidenceis available to support this thesis.

• The extrapolation of carcinogenic and non-carcinogenic effects in animals to effects inhumans may not be appropriate for all constituents, particularly if there are large speciesdifferences in metabolism of the constituent.

• While the USEPA has established a weight-of-evidence classification for carcinogens, thecancer risk equation sums all carcinogens equally whether they are known humancarcinogens (Class A) or suspect carcinogens (Class C).

Each of these three uncertainty factors tend to overestimate carcinogenic risk. There are alsoquestions concerning the summation of carcinogenic risks when different constituents havespecific target organs or induce quite different neoplastic disease states.

Non-carcinogen Toxicity ValuesToxicity values derived to estimate chronic dosages that may induce non-carcinogenic adverseeffects also have a number of limitations. Unlike cancer risk assessment, by convention, non-carcinogen adverse effects are assumed to occur in a dose-response manner only after a thresholddose has been exceeded. This is the basis for the use of the reference dose (RfD) or referenceconcentration (RfC) in estimating hazards associated with exposure to constituents. Theestimated chronic daily intake (GDI) dosage is divided by the RfD or RfC. If this ratio is > 1.0,the exposure is considered to be hazardous and this hazard index is used to qualitatively rank thepossibility of adverse non-carcinogenic effects occurring. This process is repeated for eachconstituent for all routes of exposure in summing the cumulative hazard index for the exposurescenario. The following uncertainties are probable with the use of the hazard index to describenon-carcinogenic health hazards:

• Reference doses are derived from no-observed-adverse-effect-level (NOAEL) or lowest' observed-adverse-effect-level (LOAEL) doses determined from animal studies or human

EDIS/ENG/ay071494jp6 6-68SLR-0010694

exposure investigations. Depending on die quality of the data used to determine the noobserved or lowest observed adverse dose, die NOAEL or LOAEL is divided by anuncertainty factor that can range from 1 to 10,000. The larger the uncertainty factor, theless confidence can be placed in the calculated RfD or RfC. Large uncertainty factors areused in extrapolating animal effects to human effects, and effects observed for shortexposure times compared to life-time exposures. This conservative approach tends tooverestimate non-carcinogenic hazard indices.

• The hazard index approach assumes that all non-carcinogenic adverse effects are additive.While this approach may be sound for assessing a series of constituents that have similarmodes of action and act on the same target organ (e.g., chlorinated alkene solvents), suchan approach is clearly not appropriate for combining potential adverse effects forconstituents with very different target organs and toxic insult outcomes (e.g., manganeseand arsenic).

• The addition of hazard indices determined from different pathways to calculate acumulative hazard index for an exposure scenario can often generate a very large number.It must be kept in mind that the hazard index is a ratio of an estimated exposure comparedto a "safe" exposure dose. If this ratio exceeds 1, a health hazard is indicated. It iswrong, and would be a misnomer, to place emphasis on a large calculated cumulativehazard index value being an indicator of the probability of adverse effects to occur. Afterthe hazard index exceeds 1, the magnitude of the hazard index has little bearing on thepotential severity of adverse effects that may be anticipated.

6.1.5.4 Risk CharacterizationThere are a number of factors mat contribute to uncertainties in this risk characterization. Theseuncertainties are attributable to the risk characterization procedure itself and to several site-specific factors.

The summation of carcinogenic risks from individual constituents to derive a total carcinogenicrisk from a given environmental medium (eg. soil, groundwater, surface water, or sediment) maynot be applicable. Each individual constituent of concern may act on a different organ or systemin the human body; therefore, summing the effects from these different constituents may grosslyover-estimate the potential risks from multiple constituents. Additionally, antagonistic orsynergistic effects are not accounted for in this characterization, resulting in potential over- orunder-estimations of carcinogenic risk.

The dermal absorption of COCs through contact with soil and sediment may be underestimatedfor exposure pathways concerning skin contact with these media. At present the USEPA Regionn recognizes dermal absorption factors only for PGBs, dioxin, and cadmium. Thus, dermalabsorption of organic COCs, such as benzo(a)pyrene and bis(2-ethylhexyl)phthalate were not

EDIS/ENG/ay071494.rp6 6-69SLR-0010695

calculated in these dermal exposure pathways. Inorganic COCs, such as arsenic and manganese,as with most metals, are poorly absorbed through the skin and most probably would not resultin significant contributions to the exposure to these inorganics.

A significant level of uncertainty is introduced into the future land use scenarios of thisassessment through the use of a hypothetical aquifer. This groundwater source was created perUSEPA guidance by combination of three groundwater data sets collected in the SRI remedialinvestigation. Although it is possible that the site could be developed for residential purposesat some time in the future, potable wells would normally be screened in a single groundwaterunit, and would, therefore, not produce water from the three groundwater units combined.Therefore, the future use scenario utilizing die three groundwater units combined, is ahypothetical scenario and most likely would ot occur.

6.1.6 SummaryA human health risk assessment was performed for the SRI site in Lisbon, New York toinvestigate potential risks to receptor populations on-site and in the near vicinity of the facility.This risk assessment, conducted in accordance with the Risk Assessment Guidance for Superfund,Volume I, Human Health Evaluation Manual (USEPA, 1989a), examined potential exposures toand the corresponding health risks and hazards associated with site-related constituents ofconcern. Separate risk analyses were conducted for both current land-use and possible futureland-use of the site. Samples were collected from all environmental media of concern (i.e.,surficial soil, groundwater, sediment, and surface water) to quantify constituent concentrations.The resulting analytical data from remedial investigations conducted at the SRI site and vicinityin 1992 and 1993 were used as the data base for this risk assessment.

Groundwater is the principal medium of concern at the SRI site. Acetone was the majorcontributor to the non-cancer health hazard index and arsenic was the major contributor to cancerrisk through residential usage of groundwater in the future land-use scenarios for both on-site andoff-site residents. In this future land-use scenario, unacceptable cancer risk and non-cancer healthhazards were indicated for a hypothetical groundwater aquifer used as the drinking water source.However, it is emphasized that site-related constituents are not impacting off-site residential wellsat this time.

For on-site exposure to surficial soil, sediment, and surface water in both current and future land-use scenarios, arsenic (probably naturally-occurring) was the principal COC for all incidentalingestion pathways. Additional risk/hazard estimates for dermal contact exposure pathways were

EDIS/ENG/ay071494jp6 6-70SLR-0010696

driven by a limited number of constituents (Le., benzo(a)pyrene, pentachlorophenol) at low (e.g.2/40) frequencies of detection.

Constituents of ConcernAnalytical data sets for the four environmental media were scrutinized by an independentvalidator to examine data quality, and were then evaluated for useability in risk assessmentthrough statistical analyses and best professional judgment. Using the highest detectedconcentration values for all constituent concentrations detected in each medium, a risk screeningprotocol identified the constituents of concern (COCs) in each environmental medium. Inaddition to Class A carcinogens, all COCs that contributed >1% of the carcinogenic risk or non-carcinogenic adverse health effects in the risk screening procedure were identified for inclusionin the definitive risk assessment. Table 6-6 summarizes analytical data of the COCs for eachenvironmental medium.

Exposure AssessmentA number of exposure pathways were evaluated in die exposure assessment to estimate chronicdoses of COCs by on-site and off-site populations. These pathways are diagrammed in theConceptual Site^iodel (Figure 6-1). Exposure parameters specific to each exposure scenariowere used in combination with the exposure point concentrations for each constituent of concern.Reasonable maximum exposure (RME) is included, unless that RME analysis indicated potentialrisk above EPA's target criteria (l.OE-04 for carcinogenic risks; 1.0 for non-carcinogenichazards). If so, an average case exposure scenario (Central Tendency Exposure) is analyzed foreach exposure pathway.

General uncertainties related to the conservative nature of the risk assessment process areespecially apparent in exposure assessment. The USEPA paradigm for human health riskassessment presently requires the use of point estimates for all parameters of importance. Therepeated use of upper bound estimates for COC levels, ingestion quantities, andfrequency/duration of exposure events leads to conservative exposure assessments. However,such conservative quantification of exposure is justified for baseline risk analyses as it providesassurances that sensitive sub-populations are included in the analyses.

Toxicity AssessmentThe toxicity assessment component of human health risk analysis is based on the use of USEPA-derived toxicity values for both carcinogenic risk calculations (i.e., slope factors), and for non-carcinogenic adverse health effects (i.e., reference doses).

EDIS/ENG/ay071494jp6 6-71SLR-0010697

The chronic toxicity and adverse health effects associated with principal COCs driving the risksat the SRI site are listed below. Each COCs carcinogen classification and the uncertainty factorrelated to its non-carcinogenic adverse health effects are as follows:

Acetone: A USEPA Class D carcinogen; not considered a carcinogen in thisassessment The noncancer toxicity value has an uncertainty factor of1,000. The kidney and liver are target organs.

Arsenic: A USEPA Class A known human carcinogen; cancer slope factors areavailable for oral and inhalation exposure. The lung is the target organ ofprimary tumor sites. The noncancer toxicity value has an uncertainty factorof 3.

Benzo(a)pyrene: A USEPA Class B2 probable human carcinogen; slope factor is availablefor oral exposure. Noncancer effects were not evaluated.

Manganese: A USEPA Class D carcinogen; not considered a carcinogen in thisassessment The noncancer toxicity value has an uncertainty factor of 1.

Pentachlorophenol: A USEPA Class B2 probable carcinogen. The liver and kidney are targetorgans. The noncancer toxicity value has an uncertainty factor of 100.

Risk Characterization

Current On-site Trespasser ExposureThe calculated carcinogenic risk and hazard index values indicate that USEPA recommendedguidelines are not exceeded under current on-site land-use by adult and older children trespassers.

Future On-Site Residential ExposureThe cumulative carcinogenic risks to future residents being on the SRI site exceed the USEPArecommended guidelines, and were calculated to be 2.34E-04 and 1.4SE-04 (see Table 6-12) foradults and children, respectively. Groundwater contaminated with arsenic accounts for 62% ofthe residential carcinogenic risk. The majority (>99%) of the non-carcinogenic risk of the siteis also attributed to groundwater contaminated with acetone.

6.2 Environmental AssessmentThe objective of the Environmental Assessment at the Sealand Restoration, Inc. (SRI) site is toassess the potential risk of site-related contaminants upon the ecosystems in and around the site.This Environmental Assessment evaluates potential adverse impacts associated with estimatedexposure concentrations relative to maximum acceptable exposure concentrations for selected

EDIS/ENG/ay071494j-p6 6-72SLR-0010698

ecological receptors. This assessment is <V«ignaH to be protective of the environment andconservative in nature, and may, therefore, overestimate actual receptor exposure levels. ThisEnvironmental Assessment was conducted as a site-wide assessment, covering all areas locatedat the SRI site, including the open fields, forested areas, wetlands and tributaries.

Section 6.2.1, Ecological Descriptions, describes the general ecology of the major ecosystemtypes at the site. Section 6.2.2, Identification of Constituents of Concern, identifies the site-related constituents that will be analyzed in detail as to their potential effects on the biota at thesite. Section 6.2.3, Selection of Target Species describes the methods used to select a smallnumber of species that will be used as indicators of potential adverse environmental impact.Section 6.2.4, Exposure Assessment, describes the potential exposures of on-site and nearby biotato site-related contaminants. Section 6.2.5, Risk Characterization, describes the potential risksto ecological receptors from site-related contaminants Section 6.2.6, Uncertainty Analysis,describes the uncertainties in each step of this environmental assessment, and Section 6.2.7summarizes the results of this assessment

6.2.1 Ecological DescriptionsThis section provides a general ecological description of the SRI site. The project area ischaracterized by a mixture of broad-leaved deciduous and coniferous forested areas, scrub/shrubareas, emergent marsh areas, and upland old field areas. Surrounding land-use is a mixture ofrural properties, small farms with cultivated fields and land for livestock grazing. Ecologicaldescriptions of the site are divided into three habitat types: aquatic, wetlands, and terrestrial.Additional sections discussing soil ecology; vegetation survey results; and rare, threatened, andendangered species information are also presented.

An ecological survey of the SRI site and its surrounding environs was performed in September1992. The primary objective of the field investigation was to determine the location and extentof terrestrial, wetland, and aquatic habitats, and their associated species assemblages and the


SLR-0010699

degree of human (physical/chemical) disturbance, particularly stresses associated with a hazardouswaste site. Methods of species identification included the observation of species-specific tracks,scat, dwelling type or signs thereof, and the audible calls or songs of the individual animals.Identification of vegetation, presence or absence of surface water, and soil type are some of themethods used in classifying habitat types. Detailed methodology is provided in Chapter 2.0.

Lists of the avian species, mammalian species, and vegetative species identified during theSeptember 1992 field investigation are presented in Tables 6-14, 6-15, and 6-16, respectively.

6.2.1.1 Aquatic HabitatsThe on-site types of aquatic environments of the SRI site are limited to two main types:tributaries and seasonally inundated areas. Neither of these were observed to support fishpopulations; the low dissolved oxygen content of these surface water bodies prevents their use

as fish habitats; but they could support macroinvertebrates and serve as amphibian breedinggrounds. Off-site aquatic habitats include Sucker Brook, seasonally inundated areas and smallponded areas. General water quality parameters were measured for all surface water samplingstations as discussed earlier in this report. The in-situ water quality measurements are presentedin Table 6-17.

TributariesThe on-site tributaries are the northwestern and eastern tributaries to Sucker Brook. Both ofthese tributaries flow off-site through culverts, emptying into Sucker Brook, whose ultimate pointof discharge is the St. Lawrence River. The flow and cross-sectional area of the tributaries weremeasured during the fall (September 1992) sampling event and the results are presented inSection 3.4 of this report.

Seasonally Inundated AreasThe entire eastern and northwestern portions of the site are characterized by seasonallyinundated/wetland areas. The amount of water present in these areas is a direct function of theamount of precipitation that is received by the area. The amount of precipitation received variesgreatly, depending on season. Seasonal variations in precipitation can be attributed to theinfluence of Lake Ontario. This lake tends to cause a reduction in precipitation in summer andan increase in winter. Section 3.3 gives a detailed description of the climatic conditions for thisregion.

These areas arc dominated by typical wetland vegetation species, such as cattail (Typhaaugustfolia) and arrow-wood (Viburnum dentation) and function as the headwaters for the easternand northwestern tributaries to Sucker Brook. A detailed discussion of these areas is presentedin Section 6.2.1.2.

Sucker BrookThe main surface water body that receives runoff/discharge from the SRI site and its surroundingenvirons is Sucker Brook. It exists to the north and northeast of the boundary of the site. SuckerBrook flows northward and ultimately discharges into the St Lawrence River.

Ponded AreaA medium-size pond of approximately 300 square feet exists off-site to the northwest of thewetland in the northwest corner of the site area. The banks of the pond are heavily vegetatedwith cattail (Typha augustifolia). Its water is supplied by the seasonally inundated areas aroundit. It is relatively shallow in nature with a maximum depth of about one meter. Such an areacan serve as a drinking and/or bathing source for many different terrestrial and avian animals.It also provides sufficient habitat for frogs and other amphibians and reptiles, as noted during thefield investigations. Larger animals may also use this pond as a feeding area for such species.

6.2.1.2 WetlandsThis section describes the type and extent of wetlands identified within the 210 acre SRI site.Wetlands generally include swamps, marshes, bogs and similar areas. Three parameters that arediagnostic of wetlands are: (1) the land is dominated by hydrophytes; (2) the substrate isundrained hydric soil; and (3) the substrate is saturated with groundwater or flooded for asignificant part of the growing season each year (FICWD, 1989). The on-site wetland boundaryis presented in Figure 6-10. The National Wetlands Inventory Map and New York StateFreshwater Wetlands map which were used to focus the field delineation are presented in Figures6-11 and 6-12, respectively.

The wetlands on site are part of a larger wetland complex identified on New York StateFreshwater Wetlands Map, (St Lawrence County Map 16 of 69), as LI-8 Class IE Shrub Swampand LI-10 Class IV, Predominantly Coniferous, in the southern and eastern portions of the siteand LJ-12 Class n Emergent Swamp in the western comer of the site. Based on the New YorkState Freshwater Wetlands Maps, wetland U-8 is approximately 64.20 acres of which 19.83 acresare within the site boundaries, LI-10 is approximately 25.20 acres of which 12.17 acres are within

the site boundaries, and LI-12 is approximately 7.38 acres of which 2.26 acres are within the siteboundaries.

The U.S. Fish and Wildlife Service National Wetlands Inventory Map (NWI Map) for the siteindicates four types of wetlands within the site boundaries. In the southern portion of the site,the NWI map indicates that the wetlands are Palustrine broad-leaved deciduous forested;seasonally saturated (PF01E). Along the eastern boarder of the site, the NWI map indicates matthere is a mixture of Palustrine emergent; narrow-leaved persistent seasonally saturated (PEM5E)wedands and Palustrine scrub/shrub; broad-leaved deciduous seasonally saturated (PSS1E)wetlands. In the western comer of the site, the NWI map indicates that there are additionalPF01E wetlands and a small pond located in vegetation area "S" listed as Palustrine open water,intermittently exposed/permanent; excavated (POWZX). Based on the NWI map there isapproximately 441.59 acres of PF01E wetlands within the limits of the mapped wetlands ofwhich 104.35 acres are within the site boundaries, 25.86 acres of PEM5E wetlands within thelimits of the mapped wetlands of which 18.9 acres are within die site boundaries, 99.48 acresof PSS1E wetlands within the limits of the mapped wetlands of which 32.70 acres are within thesite boundaries, and a 4.87 acre pond (POWZX) on site.

The field delineation indicates that there have been changes in the wetland composition of diesite. A number of wetland types were identified on the site. A large portion of die siteswedands are a mixture of coniferous and deciduous forested wetlands. There are approximately65.9 acres of coniferous forested wetlands and 4.10 acres of deciduous forested wedands on site.Approximately 8.95 acres of Scrub/shrub wetlands were also identified on site. Emergentwetlands, dominated by grasses, rushes, sedges and forbs, were identified on the site. There areapproximately 8.91 acres of emergent wetland on site and 5.15 acres of wet meadow on site.The last type of wetland identified on the site is old field wedands. These wetlands are relativelyrecently occurring wetlands for the site. They are forming on the edges of abandoned agriculturalfields. They may have historically have been wetland areas that were tile drained to createagricultural areas and as the fields are abandoned, and the drainage systems failing, the fields arereverting back to wetland. There are approximately 15.64 acres of old field wetland on site.

Wetland VegetationA large wetland area extends along the eastern portion of the site down to the southern portionof the site. This particular wetland is associated with the eastern tributary to Sucker Brook whichtransects the site in the south and southeast. This area was identified as a forested wetland witha mixture of broad-leaved deciduous and coniferous species. The forested wetlands were

EDIS/ENG/ay071494jp6 6-86SLR-0010712

dominated by northern white cedar (Thuja occidental, FACW), tamarack (Larix laricina,FACW), balsam fir (Abies balsamea, FAC), yellow birch (Betula alleghaniensis, FAC), blackbirch (Betula lenta, FACU), American elm (Ulmus americana, FACW), basswood (Tiliaamericana, FACU), red maple (Acer rubrum, FAC), black ash (Fraxinus nigra, FACW), riverbirch (Betula nigra, FACW), balsam poplar (Populus balsamifera, FACW), and commoncottonwood (Populus deltoides, FAC) in the canopy layer. The most common understory specieswere saplings of red maple, American elm and yellow birch, and common prickly ash(Zanthoxylum americanum). Bunchberry (Cornuscanadensis, FAC), jack-in-the-pulpit (Arisaematriphyllum, FACW), spotted Joe-pye-weed (Eupatorium maculatum, FACW), hooded ladies'tresses (Spiranthes romanzoffiana, OBL), and several species of fern; cinnamon fern (Osmundacinnamomea, FACW), New York fern (Thelypteris noveboracensis, FAC), sensitive fem (Onocleasensibilis, FACW), royal fem (Osmunda regalis, OBL), and ostrich fem (Matteucia struthiopteris,FACW) were common ground cover species.

Another tributary, the northwestern tributary to Sucker Brook, transects the northwestern edgeof the site and has a similar forested wetland community associated with it. Gray birch (Betulapopulifolia, FAC) and red-osier dogwood (Cornus stolonifera, FACW+) were found in the canopyand shrub layer, and shining clubmoss (Lycopium lucidulum, FACW-) was a common groundcover.

Scrub/shrub wetlands were found along the edges of the forested wetlands. The vegetation wasdominated by willows and included bebb willow (Salix bebbiana, FACW), hoary willow (5.Candida, OBL), meadow willow (S. gracilis, OBL), sandbar willow (S. interior, OBL), and blackwillow (5. nigra, FACW). Other shrub species included red osier dogwood, American alder-leaved buckthorn (Rhamnus alnifolia, OBL), and young balsam poplar, common cottonwood, andred maple saplings.

Emergent wetlands were found adjacent to the scrub/shrub areas and dominated by grasses,rushes, sedges and forbs. These herbaceous plants encroached in the wetter areas that are floodedwith standing water much of the year. Emergent plants included common cat-tail (Typhalatifolia, OBL), purple loose strife (Lythrum salicaria, FACW+), black bulrush (Scirpusatrovirens, OBL), softstem bulrush (Scirpus validus, OBL), woolgrass (Scirpus cyperinus,FACW+), yellow sedge (Carexflava, OBL), tussock sedge (Carex stricta, OBL), rice cut-grass(Leersia oryzoides, OBL), bog reed grass (Calamagrostis inexpansa, FACW), and reed canarygrass (Phalaris arundinacea, FACW+).

EDIS/ENG/ay071494.rp6 6-87SLR-0010713

Old field wetlands consisted of such plants as sedges, rushes, grasses, and sometimes willows.This cover type occurred within or at edges of a hay field in the northwestern and eastern portionof the site. It also existed alongside drainage ditches which lined both sides of the gravel accessroad (Newcomb Road) at the entrance to the site. Depending upon the degree of wetness theseareas may be mowed. The most common species found in these areas were path rush (Juncustenuis, FAC-), tall goldenrod (Solidago altissima, FACU-), smooth goldenrod (Solidago gigantea,FACW), wild carrot (Daucus carota), New England aster (Aster novae-angliae , FACW-). NewYork aster (Aster novi-belgii, FACW-), flat-topped white aster (Aster umbellatus, FACW), smallwhite aster (Aster vimineus, FAC), spotted-Joe-pye-weed, red-osier dogwood, hoary willow, andblack willow.

Several of the species listed are nonhydrophytic indicators (FACU). However, saturated hydricsoils as well as field indicators of wetland hydrology were also present in these areas. Therefore,they were identified as wetlands. The majority of the on-site wetlands contain hydrophyticvegetation (FAC, FACW and OBL), and display hydric soils and wetland hydrology.

Wetland FunctionsThe wetlands on site are part of a larger wetland complex that serve as the headwaters for thenorthwestern and eastern tributaries of Sucker Brook. Both tributaries flow off site throughculverts and feed Sucker Brook. Sucker Brook is a tributary to the St. Lawrence River. As thesource for these tributaries the wetlands serve as regulators and purifiers of surface water runofffrom the agricultural fields and roadways. They also act as a filter and purifier for groundwatersupplies. Wetlands trap sediments, filter and/or biofilter certain pollutants, and reducedownstream flood hazards by acting as storage areas for excess surface water runoff. Floodedwetlands can, in turn, recharge groundwater supplies and act as reservoir for surface waters whichhelps to maintain continuous stream flow during droughts.

In addition to the water management functions of site wetlands, they also provide food, cover,and breeding habitat for water fowl and other wildlife. These wetlands support diverse ecologicalcommunities as well as an endangered plant species as described in Section 6.2.1.6.

6.2.1.3 VegetationVegetation on the site was characterized by a visual assessment and consists of several differentvegetative communities. Figure 6-13 shows cover types delineated for the SRI site and thesurrounding 0.5 mile radius area. Aerial photography, existing maps, and site descriptions wereused-to characterize the general habitat and vegetative cover for the site and surrounding area.

SLR-0010715

Vegetative signatures were identified and delineated on an aerial photograph prior to fieldverification. During the September 1992 ecological survey, vegetative signatures were fieldverified by establishing transects within each vegetative signature and characterizing the mostabundant species and cover class along those transects. These visual classifications correspondedroughly with the Braun Blanquet cover scale (Moore and Chapman, 1986). The SRI site wasintensively surveyed by IT biologists and a map of vegetative cover types was compiled. Thearea surrounding the site was also surveyed, but not as extensively.

The wetland vegetation communities located in the eastern and northwestern portions of the studyarea, are described above. Approximately 52 percent (108.65 acres) of the site is wetlands.These wetlands serve as the headwaters for the two tributaries of Sucker Brook and play animportant role in water management for the site as well as providing diverse wildlife habitat.

Upland areas that occur on-site are primarily farm land which have most recently been used togrow and harvest hay and abandon farm fields. Hedgerows separate the fields. A complete listof plant species found in the upland and wetland communities is presented Table 6-17. Theupland portions of this site generally display nonhydrophytic vegetation. Several species withhydrophytic indicators (FAC, FACW), and may occur in areas classified as upland. These areasdo not display hydric soils or wetland hydrology and are consequently uplands.

The majority of the upland areas are abandoned farm land which have become old fields. Theseareas are situated in the central, northern, and northeastern portions of the site. The vegetationin the old fields is dominated by a variety of grasses. Several of these fields are periodicallymowed and the vegetation used as hay. Hedgerows separate each of the fields and several of thespecies found along them include white poplar (Populus alba), red maple, American elm,flowering dogwood (Cornusflorida, FACU-), black cherry (Prunus serotina, FACU), grape (Vitisspp.), Virginia creeper (Panhenocissus quinquefolia, FACU), common lilac (Syringa vulgaris),white ash (Fraxinum americana, FACU), pin cherry (Prunus pennsylvanica, FACU-), blackcherry (Prunus serotina, FACU), hawthorne (Crataegus spp.), gray birch, and staghorn-sumac(Rhus typhina).

This patchwork of habitat types provides (agricultural and old fields separated by hedgerows)creates excellent habitat for a number of game and nongame species. The upland/wetlandtransition areas and hedgerows provide an edge ecotone favored by many species. Theagricultural and old field habitat provide good feeding areas while the old fields also providenesting habitat for passerine birds and small mammals.

6.2.1.4 SoilsThe soil complex for the SRI site and the surrounding 0.5 mile area is a simple one. Thenorthern and eastern portions of the site are dominated primarily by prime farmland soils (SoilCorrelation of St. Lawrence County, September 1992). The western portion is dominated bywetland type soils, and the southern area by fine-sandy loam.

The St. Lawrence County, New York Soil Survey (1978) maps eighteen soil types within the 210acre site. These include: Raquette sandy loam, 0 to 3 percent slopes (RaA); Hogansburg finesandy loam, 0 to 3 percent slopes (HnA); Hogansburg fine sandy loam, 3 to 8 percent slopes(HnB); Stockholm loamy fine sand (Sg); Deford loamy fine sand (Dd); Grenville fine sandyloam, 3 to 8 percent slopes (GrB); Grenville fine sandy loam, 8 to 15 percent slopes (GrC);Waddington gravelly sandy loam 3 to 8 percent slopes (WaB); Waddington gravelly sandy loam,rolling (WaC); Swanton fine sandy loam (Sw); Adjidaumo silty clay (Ak); Mino fine sandy loam(Mh); Dorval muck (Dr); Malone loam, 0 to 8 percent slopes, very stony (MbB); Hogansburgand Grenville soils, 0 to 8 percent slopes, very stony (HrB); Munuscong mucky fine sandy loam(Mn); Udorthents, refuse substratum (Un), and pits, gravel and sand (Pg). Six soil types, theStockholm loamy fine sand (Sg); the Deford loamy fine sand (Dd); the Swanton fine sandy loam(Sw); the Adjidaumo silty clay (Ak); the Dorval muck (Dr), and the Munuscong mucky finesandy loam (Mn) soils are classified as hydric according to Hydric Soils of St. Lawrence Countyand the SCS (1987).

Figure 6-14 is a mapping of the soil complex for the SRI site and 0.5 mile surrounding area.Table 6-18 lists the soil types for the above area and a description for each one.

Numerous soil borings were taken and field analyzed during the wetlands delineation. Fieldobservations of on-site soils indicate the presence of hydric soils in areas identified as wetlands.These results correspond with the SCS soils mapping of St. Lawrence County, New York.

6.2.1.5 Hydrologlcal AssociationsThe hydrology at the SRI site is driven by local precipitation to on-site tributaries to SuckerBrook and their headwaters. The tributaries which transect the property in the northwest andeastern portion of the site are considered intermittent low-flow streams that eventually flow intoSucker Brook. Sucker Brook is situated to the east of the northeast boundary of the site andflows north into the St. Lawrence River.

The topography of the site is characterized by nearly level, to gently sloping hills with a slightlydepressed area to the east. Because of the topography on-site and in the surrounding areas, thewetlands have expanded to create a broader floodplain along the tributary, especially along theeastern boundary down to the southern boundary.

The wetland areas of the site exhibit ponded and/or saturated soil conditions as well asmorphological indicators of wetland hydrology. These morphological indicators includedadventitious roots, surface root systems, buttressed tree trunks, multiple trunks, debris and driftlines, sediment deposits on vegetation, and water-stained leaves. Upland areas of the site did notexhibit saturated soil conditions or hydrologic indicators such as those mentioned above.

6.2.1.6 Rare, Endangered and Threatened SpeciesThe SRI site and the surrounding 0.5 mfle area were surveyed for the presence of rare,endangered, and threatened species and the potential for such species to be present based on theexistence of suitable habitat. A detailed description of the field methods used can be found inSection 2.3.4.

Season can have a large impact on the presence or absence of species. Summer and spring arefrequently the best times of year for a high species diversity. During fall, some animals beginto migrate for the winter. Hibernating animals, in addition to the migratory ones, would beabsent during the winter months.

The large amount of wetlands present both on- and off-site in the northwestern, eastern andsouthern portions of the study area could provide suitable habitat for a variety of such species.A rare species and unique habitat list, provided by the New York Natural Heritage Program, wasused as a guide in assessing the area; however, the scope of field surveys was not limited tolisted species. All species observed were noted and recorded. Table 6-19 presents those specieslisted in the New York Natural Heritage database in the eight townships surrounding the SRI site.All observed species were referenced against this listing to verify their status.

Of all of the species observed in the study area, only one species was listed on the New YorkNatural Heritage Program list as an endangered/threatened species. The species observed wasthe clearweed (Pilea fontana), located in the wetlands. There have been other sitings of thisspecies on quadrangles adjacent to the SRI site. It is a facultative wetland plant speciescommonly found in wet, boggy or springy soil areas.

Heron rookeries are listed as significant habitats by the New York Natural Heritage Program onthe Reusselaer Falls and Heuvelton USGS 7.5 minute series quadrangles. Even though thesehabitats do exist beyond the 0.5 mile area surrounding the site, a potential still exists for variousheron species to use the area as a feeding or stopover zone while in route to the rookeries.Several great blue heron (Ardea herodias) were seen on-site during the September 1992 fieldinvestigations. Table 6-20 lists those significant habitats in the vicinity of the SRI Site (NewYork Natural Heritage, 1992), none of which were present in the SRI site.

6.2.1.7 Value of Fish and Wildlife ResourcesThe SRI site and the surrounding 0.5 mile area was surveyed qualitatively to determine theoverall quality of the ecosystems and their ability to support biotic communities. Historical datawere also used in assessing the ability of the study area to support fish and wildlife species.

The value of a particular habitat is determined by the degree to which animals and humans canuse the area. For animals, a habitat is of high value when it has the ability to provide shelter,food, and cover. For humans, a habitat is of high value when it provides a food and/or recreationsource. The value of a habitat to humans and animals decreases with a lessening of the abilityto utilize an area as a food, shelter, cover or recreation source.

Value of Habitat to Associated FaunaTerrestrial habitats consist of old field, cropland, forest, and wetland areas. Cover types rangefrom open in old field areas to wooded, deciduous canopies in the forested areas. All of thesehabitats could provide food, cover, and shelter for a variety of species. Open areas, being heavilyvegetated by sedges and grasses, would serve as a food and cover source for deer and smalleranimals such as rodents. Forested areas would also be an attractive dwelling for avian speciesin addition to the previously mentioned mammalian species.

Aquatic habitats include headwaters, seasonally inundated areas, tributaries, and a pond. The lowdissolved oxygen levels measured in on-site surface waters during the September 1992 fieldinvestigations eliminate the potential for any fish species to be present. Dissolved oxygen levelsranged from 0.10 mg/1 to 5.20 mg/1. Only 4 stations of the 18 surface water stations haddissolved oxygen levels above 3.0 mg/1, a level that would have the potential to support fishspecies. Thus, overall the on-site tributaries to Sucker Brook would be limited to invertebratespecies due to the lack of oxygen present in the surface waters.

The headwaters to Sucker Brook and seasonally inundated areas occur on-site. Off-site, SuckerBrook, a pond, and more seasonally inundated areas exist. These areas provide a drinking, food,and dwelling source for various types of aquatic animals, amphibians, and terrestrial animals.Aquatic mammals might use the permanent surface water bodies, such as Sucker Brook, as adwelling. The rhizomes and tubers of the cattail in the seasonally inundated areas might be usedas a food source by aquatic mammals, such as muskrats and voles.

Value of Resources to HumansThe value of resources on-site to humans is limited. The low dissolved oxygen levels measuredin the on-site tributaries prevent these surface waters from supporting fish species. Therefore,humans would not have the opportunity to fish in these waters. The most valuable vegetationcommunities are the old field, wetland, and forested areas. Old field areas are harvested and thehay is used by farmers as feed. The wetland and forested areas provide cover and forage to birdsand mammals. These areas may be used by local residents as hunting and trapping areas. Theyalso are aesthetically pleasing to viewers.

Sucker Brook is the only permanent surface water body that exists off-site in the SRI study area.It can provide a possible recreation source for the general population, in addition to habitat forlocal wildlife.

6.2.2 Identification of Constituents of ConcernThe primary stressors at the SRI site are physical, related to the original habitat alteration. Otheranthropogenic stressors include excavation, mowing and farming. This assessment focuses onthe chemical constituents potentially contaminating environmental media. Constituents ofEcological Concern (COEC) are contaminants in the envkonmental media that were used in, orresult from, past operations at the SRI site, and have the potential to adversely impact naturalpopulations or ecosystems. Identification of contaminants as COECs provides a focus for thisEnvironmental Assessment. The COECs for surficial soil, surface water and sediment arepresented in Table 6-21. The derivation of this list is presented below.

Analytical results and areal distribution of contaminants in surficial soil, surface water andsediments are presented in Chapter 4.0. Analytical data for chemicals detected at the SRI werescreened to determine which chemicals met the criteria for selection as COECs. The followingdata were included as detected concentrations:

Laboratory contaminants or contaminants which are artifacts of sampling procedures or fielddecontamination procedures may be present and are often found in virtually all environmentalsamples. USEPA's guidance for eliminating these contaminants from consideration as COECsis applied in this report. As part of the data screening process, a chemical was not consideredto be a detected concentration if the sample concentration did not exceed 10 times the highestblank concentration for all common laboratory contaminants (e.g., acetone, 2-butanone, methylenechloride, toluene, and phthalates) or five times the highest blank concentration for otherchemicals. Several laboratory contaminants were detected in field, trip, and method blanks.

EDIS/ENG/ay071494.rp6 6-103 SLR-0010729

Acetone is reported in 8 of 42 surficial soil samples ranging from 11 to 82 ug/kg. However, itwas detected in field blanks at levels ranging from 10 to 590 ug/kg. Therefore, acetone is notconsidered positively detected in surficial soils. 2-Butanone was detected in one surficial soilsample as well as a field blank at 8 fig/kg; therefore, 2-butanone is not considered positivelydetected in surficial soils. Methylene chloride was detected in 7 surficial soil samples (17-43ug/kg) and in blanks (2-21 ug/kg); methylene chloride is not considered positively detected.Chloroform was detected in two surficial soil samples (1-2 pg/kg) and in blanks at 9 ug/kg;chloroform is not considered positively detected in surficial soils. Bis(2-ethylhexyl)phthalate wasreported in 22 samples most of which were reported with associated method blank detections ofbis(2-ethylhexyl)phthalate. Field blanks report levels of bis(2-ethylhexyl)phthalate as high as 61pg/kg. The highest site sample detect without associated method blank contamination is 120pg/kg. This is less than 10 times the highest level reported in all blanks. Therefore, bis(2-ethylhexyl)phthalate is not considered positively detected in surficial soils.

Surficial soil field blanks also contained detectable levels of di-n-butyl phthalate, methoxychlor,heptachlor, endrin aldehyde, endosulfan sulfate, 4,4'-DDT, 4,4'-DDD, gamma-chlordane, andphenol. However, site sample levels are reported greater than 10 times the highest blankconcentration. Therefore, these are regarded as positive detects and not eliminated fromconsideration as COECs based on blank contamination.

Bis(2-ethylhexyl)phthalate, acetone, bromodichloromethane, chloroform, dibromochloromethane,and toluene were reported in surface water blanks. All surface water sample concentrations ofbis(2-ethylhexyl)phthalate, bromodichloromethane, chloroform, and dibromochloromethane werebelow 10 times the highest blank concentration. Therefore, these constituents are not consideredpositively detected in surface water. Only one reported value of toluene exceeds 10 times thehighest blank contamination. This is considered a positive detect. Acetone in field blanks andall but two surface water samples were rejected during validation. The two remaining surfacewater samples are considered positive detects.

Chemicals that are infrequently detected may be artifacts in the data due to sampling, analytical,or other anthropogenic contamination. Chemicals which were positively detected in less than 5percent of the soil samples from the site were eliminated as COECs. Thallium, delta-BHC,aldrin, endosulfan I, dieldrin, aroclor-1016, aroclor-1221, aroclor-1260, endrin aldehyde, phenol,4-methylphenol, diethyl phthalate, butyl benzyl phthalate, benzo(b)fluoranthene,benzo(k)fluoranthene, and benzo(g,h,i)perylene were positively detected in less than 5 percent ofthe surficial soil samples; therefore, these were not considered COECs.

EDIS/ENG/ay071494jp6 6-104 SLR-0010730

For surface water and sediments this screening procedure could not be applied since the totalnumber of samples for each of these media was less than twenty. Therefore, for surface waterand sediments, a chemical was eliminated as a COEC if there was only one detectedconcentration for that particular medium. However, if a constituent was a COEC in soil and wasonly detected once in surface water or sediment, it was retained as a COEC in that medium sinceit was assumed to be site-related. Mercury, gamma-BHC, styrene, 4-methyl-phenol, 4-chloro-3-methyl phenol, pentachlorophenol, and bromochloromethane were detected in only one of 18surface water samples and were not considered COECs. Toluene is considered to be positivelydetected only once in surface water and was not considered a COEC. Beryllium, thallium, aldrin,toluene, 4,4'-DDD, phenol, 4-methylphenol, 2,4-dimethylphenol, and 4-chloro-3-methyl phenolwere detected in only one of 18 sediment samples and were not considered COECs. Endosulfansulfate and di-n-butylphthalate were detected only once in surface water and heptachlor epoxidewas detected only once in sediment. However, these constituents were not eliminated as COECsin soil; therefore, they were not eliminated as COECs in surface water and sediment, respectively.

Some inorganic constituents such as iron, magnesium, calcium, sodium, and potassium areconsidered essential macronutrients and are generally toxic only at very high concentrations.These were not considered COECs for the SRI site.

General water chemistry parameters, such as sulfates, carbonate, bicarbonate, chloride, dissolvedsolids, and fluoride, are also generally toxic only at very high levels. Measurements of these areuseful in determining the nature of a water body being studied, but were not considered COECsfor the SRI site.

A conservative screening approach was used in establishing COECs in surficial soil by comparingarithmetic mean and exposure point concentrations on the SRI site to background conditions.Two soil borings (HB01 and MW-01D) were designated as background stations. Thiscomparison was used to determine if the on-site inorganic concentrations were elevated abovethe naturally occurring levels indigenous to the area.

Arithmetic means of on-site data for all media were calculated. Where a value was reported asnon-detect, one-half of the detection limit was used for statistical calculations. Exposure pointconcentrations were calculated as the 95% upper confidence limit (UCL) of the arithmetic meanof log normal data.

EDIS/ENG/ay071494.rp6 6-105 SLR-0010731

Background or upgradient concentrations were measured for surficial soil but not for surfacewater or sediment. Therefore, no background or reference comparisons could be made and thisscreening procedure was not employed for surface water or sediment COECs.

Aluminum, barium, beryllium, chromium, cobalt, copper, mercury, nickel, selenium, silver,vanadium, and zinc average and exposure point concentrations were at or below the average ofnaturally occurring background concentrations and were eliminated as COECs for surficial soil.Manganese, lead, and arsenic exposure point concentrations did exceed the average value of thebackground data. These constituents were retained as COECs in soil, utilizing this conservativeapproach. The exposure point concentrations and range of background concentrations arepresented in Table 6-22 for the inorganic constituents.

The potential effects of constituents are fundamental in selecting COECs. The potential foreffects to aquatic life can be assessed through comparison of surface water concentrations ofconstituents with ambient water quality criteria for the protection of aquatic life or, when theseare unavailable, threshold values as determined from the scientific literature. The state andfederal ambient water quality standards and criteria established to protect the aquatic environmentare the primary benchmark for these comparisons. The NYSDEC Ambient Water QualityStandards and Guidance Values (October 1993) designates Sucker Brook and its tributaries asClass D waters. Ambient water quality standards for Class D waters should be protective for fishsurvival and wildlife consumption of fish. These values were the primary standard used foridentifying surface water COECs. When no NYSDEC standard was available, USEPA criteriawere used. If both of these sources provided no benchmarks, then a threshold level from thescientific literature was used to identify COECs. A hardness of 300 mg/l as CaCO3 (as measuredin samples collected from the surface water bodies on-site during the September 1992 fieldinvestigation) was assumed for evaluation of hardness dependent standards. A comparison ofsurface water average and exposure point concentrations to standards or criteria is presented inTable 6-23.

The potential for effects on benthic organisms from sediment constituents can be assessedthrough comparison of the sediment average and exposure point concentrations to sedimenteffects-range median (ER-M) values (Long and Morgan, 1990), sediment criteria derived fromthe equilibrium partitioning (EqP) approach (USEPA, 1989, 1990, 1991, 1992), or sedimentlowest effect level (LEL) from Persaud et al. These comparisons are presented in Table 6-24.

The EqP approach is applicable for non-ionic organic compounds for which partitioning betweensediment carbon and interstitial water is understood. The major assumptions underlying use ofthe EqP are:

• the constituents within the interstitial water of the sediments represent the bioavailableportion of the constituents within the sediments;

• the uncomplexed interstitial water concentration of a constituent correlates with observedbiological effects across sediment types for benthic organisms;

• the concentrations at which effects occur are the same for water-only exposure; and

• benthic organisms exhibit a range of sensitivities to chemicals that is similar to the rangeof sensitivities exhibited by pelagic (water column dwelling) organisms.

Sediment criteria can be derived from the EqP approach by multiplying the surface waterstandard or criteria by the product of the fraction of organic carbon in the sediment and theorganic carbon partitioning coefficient. The lowest organic carbon content detected in thesediments at the SRI site was approximately 10 percent. This value was used for derivingsediment criteria in order to provide the most conservative estimates.

The toxicity and kinetics of inorganics in sediment are not well understood. No methodologyfor determining the bioavailable portion of metals in sediments has been developed. The primarysource of biologically effective sediment concentrations is from Long and Morgan (1990). Longand Morgan compiled data from existing studies that link concentrations of sedimentcontaminants with predicted or observed biological effects. From these orderings, concentrationsthat represent the lower 50* percentile of the data were selected. This concentration is theEffects Range-Median (ER-M) and is used as the sediment guidance value. Effects on benthicorganisms would be likely at concentrations above the ER-M.

No inorganic constituents in sediments exceeded the ER-M values; therefore, none of theinorganic analytes detected in sediments at the SRI site are considered as COECs for thisassessment. In addition, no organic constituents were found to exceed sediment criteria or effectsvalues. Organic constituents are not considered sediment COECs for the SRI environmentalassessments.

An additional source exists as a guide in establishing sediment criteria by Persaud et al (1992).A lowest effect level (LEL) is derived and to be used as a screening tool of constituents. TheLEL is the lowest point at which an effect due to a particular constituent can be observed.

EDIS/ENG/ay071494.rp6 6-110 SLR-0010736

Arsenic, cadmium, manganese, and mercury were retained as COECs in sediment. Average andexposure point concentrations exceeded LELs for all constituents except cadmium. Onlycadmium exposure point concentrations exceeded LELs.

The potential to bioaccumulate is a cause for selecting constituents as COECs with respect towildlife exposure through food chain pathways. The octanol-water partitioning coefficients (KoW)provide a rapid method for screening organic compounds on the basis of bioaccumulationpotential (i.e., tendency to occur in biota at higher concentrations than the surroundingenvironment). A log(KoW) value > 3.5 has been reported as a useful physicochemical screeninglevel for identifying xenobiotics that will potentially bioaccumulate in wildlife even if present inenvironmental media at low, non-toxic concentrations (Garten and Trabalka, 1983). Constituentswith logCKov) < 3.5 were not considered COECs for surficial soils and the terrestrialenvironment. Table 6-25 lists surficial soil organic constituents and their log(KoW) values. Allorganic constituents listed except heptachlor epoxide, alpha chlordane, gamma chlordane, andcarbazole have log(KoW) values above 3.5 and are, therefore, considered as COECs for the SRIenvironmental assessment.

In surficial soil, nineteen organic constituents were identified as COECs. Organic COECs insurficial soil are heptachlor, 4,4'-DDD, 4,4'-DDE, 4,4'-DDT, endrin, endrin ketone, endosulfann, endosulfan sulfate, methoxychlor, aroclor-1254, fluorene, phenanthrene, anthracene,fluoranthene, pyrene, benzo(a)anthracene, benzo(a)pyrene, chrysene, and di-n-butylphthalate.Three inorganic constituents were identified as COECs: arsenic, lead, and manganese.

In surface water, only aluminum and endrin were identified as COECs. Both had exposure pointconcentrations above standards or criteria.

Sediment contained no inorganic constituents above the ER-M or ER-L values. However,arsenic, manganese, and mercury exceeded the lowest effect level (LEL) as reported by Persaudet al. (1992). Therefore, these are retained as sediment COECs. All organic constituents exceptheptachlor epoxide were determined to be below sediment criteria as derived by the EqPapproach for protection of aquatic life in Class D waters. All were, however, below reportedLELs. Therefore, heptachlor epoxide was identified as a COEC in sediment for the SRIenvironmental assessment.

6.2.3 Selection of Target SpeciesThe SRI site and its surrounding environs have been described in Section 6.2.1 of this report.The SRI site is composed of old field, cropland, wetland, and forested areas. The northwestern

and eastern tributaries to Sucker Brook are located in those geographical areas of the SRI site.Both of these tributaries flow through wetland areas, both on- and off-site.

There is suitable habitat on the SRI site for terrestrial, avian, and amphibian species. Mammals,such as raccoon, could have a high frequency of exposure because they may inhabit the area fulltime. Signs of these medium sized mammals (tracks and scat) were noted during the September1992 field investigations. Exposure to contaminated soils, sediments, and surface waters couldoccur during normal daily activities.

Numerous avian species are expected to inhabit the SRI site and also use the site for feeding andbreeding activities. An appropriate avian target species should have the potential to be exposedto surface water, sediment, and soil. The American kestrel, which was observed on-site duringthe September 1992 field investigations, has a diet consisting of insects, macroinvertebrates, smallreptiles, amphibians, small mammals, and other birds. Exposure to potentially contaminated soils,sediment, and surface water could occur during daily activities.

Suitable habitat does not exist on-site for fish species to inhabit the surface waters of the SRIsite. Both tributaries occur in seasonally inundated areas, and, therefore may be dry duringportions of the year. The dissolved oxygen content of the water limits its value to fish species.These factors would inhibit the potential for fish species to exist and thrive. Macroinvertebratecommunities and some amphibians are likely to depend on these areas for propagation andsurvival.

The target species chosen for the SRI site are the raccoon (Procyon lotor), and the Americankestrel (Falco sparverius) and the meadow vole (Microtus sp). These species were chosen sincetheir feeding behavior and normal daily activities provide potential exposure to site-relatedcontaminants in sediment, surface water and soil. The raccoon and the American kestrel are bothomnivorous, that is their diet is a mixture of meat and vegetation and are therefore exposed tosite-related COECs through a number of exposure pathways. The meadow vole (Microtus sp.)was chosen as both a target species and a key prey species of the American kestrel. The meadowvole is herbivorous, lives in burrows underground, and is found throughout the United States inareas of good grass cover. The daily maintenance and cleaning activities of these species wouldalso put them in direct contact with any COECs that might be present in surface waters.

The following assumptions illustrates the conservative approach applied in defining ecologicalvariables:

EDIS/ENG/ay071494.rp6 6-113 SLR-0010739

• Target receptors are exposed chronically to upper 95% confidence interval constituentconcentrations.

• Target receptors are exposed to the constituents of ecological concern daily.

• Target receptors are exposed only to a water supply that contains the constituents ofecological concern.

• Target receptors are exposed only to a food supply that contains the constituents ofecological concern.

• Target receptors remain within the zone of impact 24 hours a day, every day of the year,for their entire lifetime.

It should also be noted that a large level of uncertainty is introduced into this assessment due tothe small size of the analytical data set. Surface water samples may or may not representconstituent contributions from the SRI site, as other potential sources of contamination exist inthe vicinity of the SRI site. This is also true of the sediment and surficial soil data.

The location of the various farms in the area surrounding the SRI site have the potential tocontribute constituents to surface water, sediment, and soils.

6.2.3.1 RaccoonThe raccoon is a widespread medium sized omnivorous mammal. They are found throughout theUnited States, Mexico, Central America, and Canada (USEPA, 1993). They occupy aquatichabitats, especially those near saltwater and freshwater marshes as they often feed onmacroinvertebrates in such habitats. Freshwater marshes might also be used for bathing anddrinking.

Raccoons eat fleshy fruits, nuts, com, grain, insects, frogs, macroinvertebrates, and eggs.Foraging might take place in abandoned farmlands, farmyards, or freshwater wetlands.

Raccoons are chiefly nocturnal, but occasionally are abroad during the day. They can adjustfeeding times to daylight hours if environmental factors offer better food yields.

Raccoons feed on a wide variety of sources depending on seasonal availability. During thespring and early summer months, raccoons typically eat more animal than plant materials. Theraccoon diet changes to one of mainly fruits during the late summer and early fall months.Winter diets consist mainly of acorns and any other corns of fruits that are still available.

EDIS/ENG/ay071494.rp6 6-114 SLR-0010740

The body size of a raccoon varies with location and availability of resources. An adult canmeasure from 46 to 71 cm in length, excluding the length of it's tail which ranges from 20 to30 cm. Weights, depending on sex and resources, may vary from 5.4 to 15.8 kg. During theirwinter dormancy, raccoons may lose up to 50 percent of their total body weight.

Raccoons present on the SRI site could be exposed to on-site contamination via several exposureroutes. Exposure to COECs in soils can be a result of feeding on worms or vegetation, or fromcleaning their fur. Surface water COECs could reach the raccoon during drinking, .eating,bathing, and swimming activities. COECs in sediment might reach the raccoon during feedingon invertebrates.

6.2.3.2 American KestrelThe American kestrel is the smallest falcon native to the United States. It is part of thestreamlined species of birds known as raptors and it is a year round resident of New York state.They consume a wide variety of animals, such as reptiles, insects, small mammals, invertebrates,and other smaller birds (USEPA, 1993).

Body sizes vary seasonally, but, are, on average, in the neighborhood of 27 cm from bill tip totail tip. Males are generally 10 to 20 percent smaller than the females. Body weights reach amaximum in winter and a minimum in summer.

Seasonaliry plays a large factor in dietary habits. Invertebrates are generally eaten year round.During the summer, the diet of the American kestrel consists mainly of large insects, dependingon availability. Small mammals and birds might also be eaten in the absence of adequatesupplies of insects. Winter diets are composed mainly of small mammals and birds.

The American kestrel is a solitary species, except during the breeding season. During this time,usually spring, males feed females and nestlings.

The potential for exposure to COECs in surface water, soils, and sediments is high for theAmerican kestrel. Feeding, bathing, nest building, and drinking activities expose this raptor toall of the potentially contaminated environmental media at the SRI site.

6.2.3.3 Meadow VoleThe meadow vole is a primarily herbivorous rodent that makes it burrows in runaways alongherbaceous vegetation. They are found throughout the United States and Canada wherever good

EDIS/ENG/ay071494.rp6 6-115 SLR-0010741

grass cover exists. They are diurnal organisms and serve as prey to many large avian predators,such as the American kestrel (USEPA, 1993).

Body sizes vary from 8.9 to 13.0 cm from head to toe and tail lengths range from 3.6 to 6.6 cm.Males are usually larger than females. Typically, meadow voles lose weight in winter and reachweight maxima in summer due to prey population availability.

Habitat is primarily grassy fields, marshes and bogs. The more grass that an area has, the morelikely a meadow vole is to take residence. Meadow voles are uncommon in areas of standingwater.

Dietary habits include succulents sedges, seeds, fungi, some insects, and animal matter. Insectsand animal matter rarely comprise more than 1% of a meadow vole's diet.

Meadow voles on the SRI site have the potential for exposure to COECs via general pathways.Their main food source, vegetation, uptakes contaminants from the soil. They also liveunderground, another direct exposure route to soil. Surface water and sediment COECs mightreach these rodents while swimming, drinking, or even eating.

6.2.4 Exposure AssessmentThe main objective of the exposure assessment is to describe and quantify any potential exposureof the local biota to site-related contaminants. The exposure assessment is divided into threeparts: exposure scenario, potential exposure pathways and media calculations, and methodologyfor calculation of target species total daily exposures. The first part of the exposure assessmentwill develop a food web for the SRI site and identify potential exposure pathways for the targetspecies. The second subsection will quantify the potential exposures of the target species to theCOECs via media calculations. The final part of this section will identify those methodologiesused in calculating the daily exposure of the target species to the COECs.

6.2.4.1 Exposure ScenarioA food web is a series of interconnecting food chains that link the producer species to theconsumer species. Primary producers, such as green plants, form the base trophic level of thefood web. They derive their energy directly from the sun. Consumers comprise the other trophiclevels at varying degrees. A primary consumer, for instance, feeds on primary producers,whereas, a secondary consumer can feed on both the primary consumer and producer levels. Anexample of the later is the raccoon. It is an omnivore, having a diet that is a mixture ofvegetation and meat. Foods webs were developed for the target species : the American kestrel

EDIS/ENG/ay071494.rp<5 6-116 SLR-0010742

(Falco spaarverius) and the raccoon (Procyon lotor). These target species best represent themajor trophic levels present at the SRI site. Figures 6-15, 6-16 and 6-17 are food webs for theAmerican kestrel, raccoon and meadow vole, respectively.

The total daily intake (mg/kg/day) for each of the target species was calculated by adding 1) theamount of constituent ingested through consumption of vegetation, 2) the amount of constituentabsorbed through direct ingestion of soil, 3) amount of constituent absorbed through ingestionof surface water, and 4) the amount of constituent absorbed through ingestion of prey. .

Exposure via the inhalation pathway was not evaluated for the purposes of the environmental riskassessment. The site is heavily vegetated and the generation of fugitive dust and volatile organicsis expected to be minimal. Therefore, the inhalation of COECs was not considered a viableexposure pathway within this ecological risk assessment.

6.2.4.2 Potential Exposure Pathways and Media CalculationsThree environmental media were examined for concentrations of site related constituents: surfacewater, soil, and sediment. All target species were assumed to be exposed to on-site mediacontamination, only, i.e. their home range is limited to the SRI site, even though they may onlyspend a portion of their time on-site. In addition, it was assumed that each target species' entiredietary intake originated from the SRI site and therefore had the potential for contamination, eventhough food collected on-site may comprise a small fraction of the target species' actual diet.This exposure is the worst case scenario for these target species.

Twenty-six constituents have been identified as being of concern in surficial soil, sediment,and/or surface water. These COECs are aluminum, arsenic, cadmium, lead, manganese, mercury,heptachlor, 4,4'-DDE, endosulfan H, 4,4'-DDD, endosulfan sulfate, 4,4'-DDT, methoxychlor,endrin ketone, endrin, heptachlor epoxide, arochlor-1254, fluorene, phenanthrene, anthracene,fluoranthene, pyrene, benzo(a)anthracene> benzo(a)pyrene, chrysene and di-n-butylphthalate. Thephysicochemical and environmental fate constants of the COECs are p.. sented in Table 6-26.

6.2.4.3 Methodology for Calculation of Target Species Total Dally ExposureTotal exposure of a target species is defined as the summation of exposure from each individualpathway. Exposure of the target species to the COECs are quantified in the following pathwaycalculations.

6.2.5 Risk CharacterizationThis section characterizes the nature and degree of adverse impact associated with the exposureof COECs to endemic target species at the SRI site. Characterization includes exposure via threemedia pathways: soils, surface water, and sediment.

Detections of constituents in surface water and sediment were initially compared to availablewater quality standards and sediment criteria. The comparisons are presented in Tables 6-23 and6-24. The total daily exposures calculated in previous sections are based on species-specificparameters. The information for the toxicity data is not, however, target species-specific.Therefore, the approach in this risk characterization is only semi-quantitative. Total dailyexposures for the target species are compared to die range of toxicity values for the organismsof concern or other organisms, as available. A qualitative presentation of the potential for effectis presented below.

Laboratory data provides information on the relative toxicity of the various compounds; thesensitivity of a diversity of species tested (usually not the target species of this assessment); theinfluence of diets and routes of administration; and variance in response due to sex, age, andreproductive status. Because the information is usually not specific to the target species, theextrapolation of laboratory toxicity tests to die field is, in most instances, uncertain andinadvisable. The numerically calculated species-specific daily intake of the constituents ofconcern are compared to the range of acute and chronic toxicity data available for the COECs.The calculated daily intake for the target species at the SRI site are presented in Tables 6-28through 6-30. These comparisons are presented in the next section. A Hazard Index (USEPA,1986) is calculated, based on these comparisons.

6.2.5.1 Inorganic ConstituentsThe inorganic COEC that exists at the SRI site are aluminum, arsenic, cadmium, lead,manganese, and mercury. The mercury exposure point concentration in sediment (0.350 mg/kg)is below the ER-M (1.3 mg/kg) but above both the ER-L (0.15 mg/kg) and the LEL (0.12mg/kg). Sediment levels elevated above these are found throughout the site.

The NYSDEC standard for Class C waters is 100 ug/f of aluminum. No Class D criteria exists.Studies conducted regarding aluminum suggest that when the pH is between 6.5 and 9.0,freshwater aquatic organisms should not be affected negatively by a chronic exposure less than87 ug/f or by an acute exposure of less than 750 ng/{ (USEPA, 1988). Acute criteria were notexceeded at any surface water station at the SRI site. However, exposure to constituents shouldbe considered a continuous and, therefore, chronic exposure. Only one sampling location at the

EDIS/ENG/ay071494jp6 6-129SLR-0010755

SRI site exceeded chronic criteria levels and the NYSDEC standard. The dissolved amount ofaluminum at this station was less than both USEPA criteria. The dissolved concentration isusually considered the bioavailable portion of the total concentration and toxic part. Therefore,the potential for sub-lethal impacts to sensitive organisms at the SRI site with respect toaluminum is minimal.

Inorganic arsenic, (i.e., arsenic combined with one or more other elements such as chlorine orsulfur) is the most commonly found form in in surface water (USEPA, 1989c). This form enterswater bodies primarily through runoff. The presence of biota in water bodies has been -knownto play an important role in determining speciation of arsenic (USEPA, 1984a). Inorganic arsenicis much more toxic than the organic form (USEPA, 1984a).

Arsenic acute toxicity, as well as sub-lethal effects, has been observed in fish and invertebrates.Toxicity can be highly influenced by temperature, pH, speciation, and many other factors.Inorganic arsenic is acutely toxic to freshwater aquatic animals at concentrations as low as 850mg/f in water and affects marine plants at concentrations as low as 13 to 56 mg/l. The ER-Lis reported as 33 mg/kg.

Trivalent arsenic is more toxic to wildlife than either pentavalent arsenic or organic arsenicals.Arsenic poisoning has been reported in acute episodes but chronic arsenosis is rarely encountered.Sensitive species of birds have died following single oral doses of 17.4 to 47.6 mg/kg bodyweight. Adverse effects in mammals were noted in single oral doses of 2.5 to 33 mg/kg bodyweight, and at chronic doses of 1 to 10 mg/kg body weight. As little as 1.7 mg/kg has beenshown to produce fetal death and malformations during critical stages of hamster embryogenesis(Eisler, 1988b).

The arsenic exposure point concentration in sediment (125 mg/kg) is below the ER-M and ER-Lvalues but exceeds the LEL (5.5 mg/kg). The elevated sediment concentrations are contained inthe wetlands directly cost of the disposal cell and to the northwest of the site. Effects in biotafrom arsenic are expected to be localized. Food chain exposure to arsenic is predicted to bebelow the LOELs reported in the literature.

Cadmium is known to occur naturally at relatively low concentrations (0.1 ug/(). The manydifferent forms that it can take complicate the level of impact it may have on a freshwatersystem. Toxicity of cadmium is hardness dependent.

EDIS/ENG/ay071494jp6 6-130SLR-0010756

Eisler (1985) reported effects of cadmium exposure to aquatic organisms including mortality,reduced growth, inhibited reproduction, and other adverse effects. A relatively large amount ofdata exists for cadmium in sediments, suggesting an ER-L of 5 mg/kg.

Freshwater acute toxicity values for cadmium range from 1 to 73,500 pg/f for fish and from 3.5to 28,000 pg/t for invertebrates (USEPA, 1980). The sediment ER-L and ER-M are reportedas 5.0 and 9.0 mg/kg, respectively. The T.PJ, is given as 1.0 mg/kg.

Lead can adversely affect survival, growth, reproduction, development, and metabolism of manyspecies. Organolead compounds are more toxic than inorganic lead compounds. Lead poisoningof waterfowl through ingestion of lead shot is a significant cause of mortality to these species.Among sensitive species of birds, survival was reduced at doses of 75 to 150 mg/kg body weight.Reproductive impairment was noted at 50 mg^cg and signs of poisoning were evident at dosesas low as 2.8 mg/kg body weight. Survival of rats was reduced at acute oral doses as low as 5mg/kg body weight. Survival of dogs was reduced by chronic oral doses of 0.3 mg/kg bodyweight (Eisler, 1988a).

The cadmium exposure point concentration in sediment (1.02 mg/kg) is below both the ER-Mand ER-L but slightly exceeds the LEL (1 mg/kg). Only two sediment samples exceeded thislevel. Both are contained east of landscaping area and adjacent to each other.. Effects on benthicbiota from cadmium exposure is expected to be very localized.

It has been shown that the removal of lead from aquatic media is pH dependent. Lead is moremobile in alkaline waters than in acidic ones (USEPA, 1984b). Lead water criteria are hardnessdependent. Lead exposure can produce many types of adverse effects, among which aremodifications of the function and structure of kidneys, bones and the central nervous system(Eisler, 1988a). Organolead compounds are generally more toxic than inorganic forms. Adverseeffects in water usually occur at concentrations ranging from 1.3 mg/( to 7.7 mg/f. From thesediment data collected an ER-L of 35 mg/kg is suggested.

Dietary exposure to lead through food chain and media to organism transfer is predicted toexceed the LOEL reported in the literature. The exceedences are predicted for the meadow volethrough consumption of contaminated plants and for the American kestrel through consumptionof contaminated prey.

Mercury occurs in the environment in three states: elemental, mercurous compounds, andmercuric compounds. Acute toxicity of inorganic mercury to freshwater invertebrates ranges

EDIS/ENG/ay071494jp6 6-131SLR-0010757

from 2.2 mg/L to 2,000 mg/L (USEPA, 1986a). Organomercury compounds, particularlymethylmercury, are more toxic than inorganic forms (Eisler, 1987) and mercury is considered themost toxic trace metal to aquatic organisms. Based on collected sediment data, an ER-L of 0.15mg/kg for mercury is suggested.

The mercury exposure point concentration in sediment (0.350 mg/kg) is below the ER-M (1.3mg/kg) but above both the ER-L (0.15 mg/kg) and the LEL (0.12 mg/kg). Sediment levelselevated above these are found throughout the site.

Manganese does not typically occur in the pure form, rather it occurs in combination with otherelements and is a common constituent found in pesticides and fertilizers (ATSDR, 1991 a). It isa vital micronutrient and is only toxic at high concentrations. Data on toxicity of manganese tofreshwater aquatic life indicate values ranging from 1.5 mg/f to over 1000 mg/f (USEPA, 1986).No acute or chronic criteria exist at the federal level nor do any standards exist at the state level.Sediment quality criteria for Ontario list an T-FflL of 457 mg/kg.

The effects of manganese on wildlife has not been extensively researched. A survival NOEL fororal exposure to rats is reported as 290 mg/kg/day whereas a system effects NOEL for mice isreported as 250 mg/kg/day.

The manganese exposure point concentration in sediment (970 mg/kg) exceeds the LEL (457mg/kg). No ER-L or ER-M are provided for manganese. Dietary exposure to manganesethrough foodchain and media to organism transfer are not predicted to exceed the LOEL'sreported in the literature.

6.2.5.2 PesticidesPesticides are synthetic chemicals originally made for the purposes of pest control and fertilizersused in lawn maintenance. Due to the harmful impacts they can cause, some, such as DDT, havebeen banned in the United States (USEPA, 1994).

Soil moisture and evaporation of water have a strong impact on the rate of volatilisation of suchcompounds from soils and sand. Constituents of this nature are more likely to adsorb to sedimentor soils, therefore, limiting volatilization. Concentrations of pesticides/PCBs are thus more likelyto be higher in sediment than surface water. They are also highly lipophilic in nature, resultingin high bioconcentration factors (BCFs).

EDIS/ENG/ay071494jp6 6-132SLR-0010758

The COECs that are of this type are heptachlor, 4,4'-DDE, 4,4'-DDD, 4,4'-DDT, endrin, endrinketone, endosulfan sulfate, endosulfan n, and methoxychlor. All of these are COECs in surficialsoils. Endrin is the only COEC of this nature in surface waters and heptachlor epoxide insediments.

Heptachlor is commonly present as an impurity in the pesticide chlordane. In much of theliterature, it is documented as being highly toxic. This pesticide is no longer available in theUnited States due to the amount of negative impacts that resulted from its use (USEPA, 1989).No observable adverse effects level (NOAEL) values in rats ranged from 750 pg/kg/day to 1350pg/kg/day. Calculated total daily exposure (TDE) values for all target species are orders ofmagnitude less than the NOAEL values. Therefore, negative impacts from heptachlor on theecological community are not expected

Three of the pesticides identified as COECs are typically not detected alone. 4,4'-DDT, 4,4'-DDE, and 4,4'-DDD are usually found as a mixture of all three constituents. DDD and DDE aredegradation and metabolic products of DDT. NOAEL values of 56 pg/kg/day and 41 pg/kg/daywere sited in the literature for 4,4'-DDT in Cooper's hawk and the red-tailed hawk, respectively(Oak Ridge National Labs, 1993). None of die calculated TDE values for the target speciesexceed these values. Negative impacts to the environment are not expected from the low levelsof DDT, DDE, and DDD present at the SRI site.

Methoxychlor is also known as methoxy DDT. It is an insecticide that is most effectivecombating mosquitos and house flies. In mammals an acute oral LDX in rats of 6,000 mg/kg isreported in the literature (1983). TDE values for this constituent are well below this value.Thus, this pesticide is not expected to present negative environmental impacts at SRI.

Endrin was used for the control of rodents and insects prior to the cessation of its production.An NOAEL for chronic exposure in rats has been determined to be between 250 and 300pg/kg/day (ATSDR, 1990). The toxicity of endrin ketone is expected to be similar. None of thecalculated TDE values exceed or approach these NOAEL values. Thus, endrin and endrin ketoneare not expected to cause negative ecological impacts at SRI.

Endrin is a COEC in surface waters as well as soil. A standard does not exist for this constituentat the NY state level, therefore, the USEPA chronic criteria of 0.0023 pg/C will be used forpurposes of comparison. Only two of eighteen samples exhibited concentrations detected abovethe method detection limit. One value was below the chronic criteria, and, the other was above

EDIS/ENG/ay071494jp6 6-133SLR-0010759

it. The presence of endrin is isolated and not prevalent across the site; therefore, it is not of highconcern for potential negative ecological impact.

Endosulfan is used for the control of insects on crops. It is possible that farmers in the area ofthe site use it for insect control and contribute to the concentrations of this constituent at the site.Endosulfan sulfate is a breakdown product of endosulfan. NOAEL values range from 800 - 2500ug/kg/day in rats (ATSDR, 1993) for endosulfan. None of the calculated TDEs for the targetspecies exceeded these values. Based on this lack of exceedance of NOAEL values, it isexpected that neither endosulfan nor endosulfan sulfate will negatively impact the environmentof the SRI site.

6.2.5.3 Polychlorinated Biphenyls (PCBs)Polychlorinated biphenyls (PCBs) are chlorinated derivatives of biphenyls, a class of aromaticorganic compounds. The production of PCBs is no longer permitted in the United States due totheir negative ecological and health impacts. Substantial portions of PCBs manufactured priorto 1971 contained up to 68 percent chlorine and are believed to still be present in theenvironment due to their persistence. Their environmental persistence and ability tobioaccumulate cause PCBs to be of potential concern (USEPA, 1980).

Each PCB congener has a different way of behaving in the environment. Some breakdown morereadily than others. It has been determined that soil moisture and evaporation have a stronginfluence on the rate of chlorinated hydrocarbon volatilization from soils and sand. PCBs arehighly lipophilic and readily bioconcentrate in animal tissue. The only PCB identified as aCOEC for the SRI site is aroclor-1254.

NOAELs for aroclor-1254 of 0.186, 0.07, and 0.035 mg/kg/day have been documented for theshort-tailed shrew, mink, and fox, respectively. For avian species, Cooper's hawk and the red-tailed hawk have NOAELS of 2,150 and 1,570 ngflcg/day, respectively. Calculated TDE valuesfor the target species at the SRI site do not exceed any of the NOAELs; therefore, negativeimpacts due to arochlor-1254 at the SRI site are not expected.

6.2.5.4 Pofycycllc Aromatic Hydrocarbons (PAHs)PAHs are chemicals formed during the incomplete burning of coal, oil, gas, wood, and otherorganics. A few such chemicals were also used to make pesticides (USEPA, 1994).

Most PAHs do not occur singularly in die environment, rather they occur as a mixture ofchemicals. They generally do not dissolve in water. PAHs have the potential to evaporate, but,

EDIS/ENG/ay071494jp6 6-134SLR-0010760

most adsorb tightly to panicles in soils or sediment. In surface water and sediment,microorganisms speed up the breakdown of these chemical complexes. Sorption of PAHs in soilis directly dependent on particle size, and organic carbon content Microbial degradation is themain degradation process for PAHs in soils. The rate of PAH breakdown depends on a varietyof environmental factors, such as pH. The amount of degradation determines the availability toterrestrial plant species. Bioaccumulation studies have been conducted for PAH compounds onhigher trophic level consumers and showed no significant affect.

All of the COECs that are PAHs were detected in surficial soils. These COECs are flnorene,phenanthrene, anthracene, pyrene, benzo(a)anthracene, chrysene, and fluoranthene.

All seven of the PAHs identified as COECs for die SRI site were treated as one class of PAHcompounds (US Department of Health, 1994). No PAH compounds were found in surface watersso this discussion will primarily focus on the surficial soils where all of the PAH COECs weredetected. NOAEL values were derived for die group, that included all seven of the SRI sitePAHs, rather than the individual constituents. A dose of 133300 ug/kg/day is reported in theliterature to have a negative impact on reproduction in rats (USEPA, 1994). None of thecalculated IDE values for the PAHs identified at die SRI site exceed this value. Thus, they arenot expected to negatively impact the surrounding ecology of the SRI site.

6.2.5.5 Dl-n-butylphthalateDi-n-butylphthalate was detected infrequently in all three media. The available aquatic data forphthalate esters indicate that acute and chronic toxicity to aquatic life occurs at concentrationsas low 940 and 3 pg/f, respectively. The effects of di-n-butylphthalate on terrestrial wildlife islimited. Eggshell thinning is reported to occur in ring doves at 1.11 mg/kg/day.

Dietary exposure via foodchain transfer may exceed the LOELs reported in the literature. Thedietary exposure is predicted based on die exposure point concentration; the exposure pointconcentration is actually greater than die maximum detected concentration because the detectionlimits for the non-detects are high. Dietary exposure calculated for detected concentrations doesnot exceed die LOELs. The risk to biota from di-n-butyl phthalate is considered minimal.

6.2.6 Hazard IndicesA Hazard Quotient (HQ) can be derived for each constituent and each species and die total dailyexposure (TDE) divided by die acceptable daily exposure (ADE) found in die literature. Further,a Hazard Index for a species can be calculated as die sum of die individual Hazard Quotientsfor diat species. Table 6-31 presents die Hazard Quotients and Hazard Indices for each species.

Only two constituents of concern have hazard quotients calculated greater than one: lead and di-n-butylphthalate. The high value for di-n-butyiphthalate is related to the high detection limitsreported for non-detects. Based on detected levels, the hazard quotient would be below one. Thehazard quotient for lead exceeds one for both the meadow vole and American kestrel. Theelevated soil levels could produce food chain transfer of lead which could effect biota. It shouldbe pointed out mat background levels of lead would also produce exceedences of the LOELs.

The Hazard Indices for all three species exceed one. Lead and di-n-butylphthalate contribute themost to the hazard indices. Manganese and arsenic are of secondary importance.

6.2.7 Uncertainty AnalysisThe precision of an ecological assessment is limited by the size and quality of the database.There are varying degrees of uncertainty associated with estimating the impacts of constituentexposure. Uncertainties of this nature have been compensated for throughout this assessment bymaking conservative assumptions where necessary. Specific areas of uncertainty include:

• Receptor species• Fate and transport estimates• Exposure estimates• Toxicological data and risk characterization• Complex interactions of uncertainty elements

These areas of uncertainty are addressed in the following sections.

6.2.7.1 Receptor SpeciesTo achieve an estimate of the potential risk to an ecological community, target speciesrepresenting various exposure pathways and scenarios were modeled. These target species wereselected because they represented the types of species that were observed on-site, and whosepotential exposures were through varied pathways. These target species were assumed to resideon-site 100% of their lives and obtained 100% of their dietary intake from on-site sources.Therefore, they are assumed to be maximally exposed to any site-related contaminants. Actualindividuals of these species probably do not spend their entire lifetimes on-site or obtain 100%of the dietary intake from the SRI site.

Although these target species were selected because they are potentially exposed to site-relatedcontaminants through varied pathways, other species exist on-site and individuals of these species

EDIS/ENG/ay071494.rp6 6-137SLR-0010763

may have greater or lesser exposures than those calculated in this assessment. Target specieswere chosen which should represent maximum exposure.

£2.7.2 Fate and Transport EstimatesMany of the constituents are subject to attenuation in soil or surface water by such processes asphotodecomposition, sorption, deposition, and biodegradation. However, the half-life valuesassociated with these fate processes are site-specific, constituent-specific, and dependent on manyenvironmental factors. Because of the uncertainty associated with measuring these fate processes,this assessment assumes that none of these processes are operative. In addition, this assessmentassumes that no transport mechanisms are acting on the environmental media at the site.Therefore, the constituent concentrations detected in the various environmental media (soil,surface water, and sediment) at the SRI site are assumed to be constant over the duration ofpotential exposure. Both of these assumptions provide an added degree of conservatism to thisassessment.

6.2.7.3 Exposure EstimatesThe exposure assessment utilized mathematical models that rely heavily on estimates of themagnitude of exposure to the constituents of concern. Analytical data that were used to quantifyexposures were the 95% upper confidence limit of the mean concentration of each constituent.Using these values as exposure point concentrations for the entire SRI site, overestimates themagnitude of potential exposure for the sake of conservation.

Paste for the Mathematical Models of Exposure AssessmentMathematical models, such as those employed in the exposure assessment, are helpful inproviding an estimate of the potential for a biological system's response given a particular setof input conditions and constraints. The assessment models provide for comparisons ofmaximum exposure concentrations to a biological system to concentrations found to cause effects.Here, the biological systems examined are the individual target receptors.

Any attempt to model a biological system incorporates some degree of uncertainty. For example,in modeling the transfer of a constituent through a food chain pathway such as forage ingestion,it is necessary to quantify the constituent transfer rates from soil to plant and from plant toanimals. If these values do not exist as a result of previous scientific inquiry, assumptions aremade that permit estimation from the best available, most relevant information. The precisionof the resulting estimate of dose incurred depends on the accuracy of these assumptions reflectingreal-world events.

EDIS/ENG/ay071494jp6 6-138SLR-0010764

In essence, the scientist has taken a system in which many variables exist and constructed amanageable model of that system by assuming those variables are constant at a defined level.This approach sets the input constituent concentration as the only independent variable in themodel. A linear relationship is assumed that is not necessarily reflective of real-world conditions.The dependent variable (the dose incurred) becomes a function of constituent concentration alone,which may not adequately represent site-specific conditions. This dose is qualified by theconstraints on the model.

6.2.7.4 Toxlcologlcal Data and Risk CharacterizationThe overriding uncertainty associated with the risk characterization is the lack of specifictoxicological data. Not all constituents have sufficient data, if any at all, for the target speciesin the toxicological literature. In addition, not all endpoints of concern for ecological assessmentare addressed. This forces the use of a range of toxicity values used as an across-the-boardspecies toxicity value. The use of non-species specific toxicity data generates a large level ofuncertainty in this risk evaluation.

6.2.7.5 Complex Interaction of Uncertainty ElementsAn ecological assessment of a site is ultimately an integrated evaluation of historical, chemical,analytical, environmental, demographic, and toxicological data that is as site-specific as possible.To minimize the effect of uncertainties in the evaluation, each step is biased toward conservativeestimations. Since each step builds on the previous one, this biased approach more man compen-sates for assessment uncertainties. In addition, these calculations do not represent currentlyexisting or expected future exposures or impacts. Rather, they are estimations that may occuronly if all of the conservative assumptions are realized. Thus, this assessment is designed to bequite conservative and, therefore, protective of the environment.

6.2.8 SummaryThe SRI site and the surrounding 0.5 mile radius area were investigated to determine existingecological conditions. All of the environs within the above mentioned study area werecharacterized and grouped into three habitat types: aquatic, wetlands and terrestrial. Observationsobtained during September 1992 field investigations were reviewed and species lists for avians(Table 6-14), mammals (Table 6-15) and vegetation (Table 6-16) were compiled.

Only one species listed within the New York Natural Heritage Program Database was observedwithin the study area. Clearwood (Pilea fontand) is a vegetative species typically found withinwetland habitats and was present on-site during September 1992 field investigation. Table 6-19


SLR-0010765

and Table 6-20 present the New York Natural Heritage identified endangered/threatened speciesand significant habitat areas in the vicinity of SRI site, respectively.

Several individual great blue heron (Ardea kerodias) were noted during field investigations. Thepresence of this species on-site may be a result of the heron rookeries which are listed as"Significant Habitat" by the New York Natural Heritage Program Database as existing in thevicinity of the SRI site.

Three target species were identified in order to calculate potential impacts to ecological receptorsas a result of the contamination present on-site. The raccoon (Procyon lot or), the Americankestrel (Falco sparverius) and the meadow vole (fdicrotus sp.) were selected as target species.

Twenty-six constituents of environmental concern were identified and evaluated for potentialimpacts to the selected target species and aquatic biota in general. A comparison of the totaldaily intake of the COECs for target species with the range of available lexicological data foundin the literature was the basis for the risk characterization. This assessment is more qualitativein nature due to the limited availability of species-specific, chemical-specific and endpoint-specific data. The combination of these factors, therefore, contribute to the uncertainty of suchcomparisons.

Total daily intakes for each of the target species were calculated as a result of the ingestion ofsoil, sediment, surface water, vegetation and food. Species-specific dietary ingestion ratesobtained from the literature were used in these calculations.

Only two of the calculated TDE values for the target species exceeded appropriate NOAELs forany of the COECs for the SRI site. These are lead and di-n-butylphthalate. However, the di-n-butylphthalate exposure point concentration used to calculate the TDE values was based on highdetection limits for non-detects. Detected concentrations do not predict unacceptable TDE values.Lead exposure is high throughout the site. Though exposure to lead may have an effect, it isimportant to point out that effect are predicted from background levels also.

It is also important to note that the nature of some of the contamination at the SRI site may notbe solely attributed to previous site activities. The area surrounding the site has a large numberof farms. Some crops even exist in the northern area of the site. The pesticides used inmaintaining the local farms could be transported to the SRI site via surface runoff or aerialdeposition. Some PAHs can also be attributed to such activities.

EDIS/ENG/ay071494.ip6 6-140SLR-0010766

In conclusion, while the SRI site exhibits low levels of contamination, it does not pose anysignificant environmental hazard above that naturally occurs. Concentrations of most COECs areat levels such that target species would not receive constituents at levels known to cause hannto the individual animals. Overall, the ecology of the SRI site is typical for such a system. Thedata shows a low potential for future negative impacts from the identified COECs.

7.0 Summary and Conclusions

A two phased investigation was conducted by IT Corporation, under contract with and on behalfof the EPA, at the SRI site in order to characterize and evaluate existing contamination at thesite. Dames and Moore conducted a previous RJ/FS under the direction of NYSDEC in 1986-1987 which recommended source removal. Between 1987 and 1990, the drum storage area,waste tanks, and disposal cell were remediated. IT conducted a Phase I Supplemental RI fieldinvestigation from September through December of 1992 to investigate any residualcontamination remaining in the environmental media after the source removal had beencompleted. The results of the Supplemental Phase I RI field investigation indicated that a secondinvestigation was necessary to characterize the nature and extent of the residual contaminationnear the disposal cell. IT conducted a Supplemental Phase II RI field investigation during Augustthrough October of 1993. The collective data set was used to characterize the hydrogeologicalconditions at the site, evaluate contaminant fate and transport, and conduct a baseline riskassessment.

This section presents a summary of the results of die remedial investigation, transport evaluationand the baseline risk assessment. Presented in detail in previous sections; "Nature and Extentof Contamination" describes the results of the remedial investigation, "Fate and Transport"describes the potential routes of contaminant migration, and "Baseline Risk Assessment"summarizes the findings of the human health and environmental risk assessments. The majorresults and conclusions of these evaluations are presented in the following subsections.

7.1 Nature and Extent of ContaminationThe major concerns on the SRI site is groundwater contamination in the overburden and bedrockaquifers and soil contamination found in the saturated soil zone adjacent to the northeasterncomer of the disposal cell. The small slug of soil contamination appears to be locatedapproximately 20 to 22 feet below grade (10 feet below the water table) and does not appear tobe significant in size.

7.1.1 Leachate Monitoring System SamplesBased upon the results of the IT Corporation Supplemental RI Phase I and Phase n investigationconducted in 1992 and 1993, the major concerns on the SRI site is groundwater contaminationin the overburden and bedrock aquifers and soil contamination found in the saturated soil zoneadjacent to the northeastern comer of the former disposal cell. The small slug of soil

EDIS/ENG/ay071494.rp7 7-1 !SLR-0010769

contamination appears to be located approximately 20 to 22 feet below grade (10 feet below thewater table) and does not appear to be significant in size.

A leachate sample was collected from the former disposal cell leachate collection system. Thefollowing organic chemicals were detected in this sample.

Note: ND = Not Detected

This leachate collection system consists of lateral drains that connect to a central collection pipewhich contains a centralized collection sump. This sample was collected from the sump locateddirectly beneath the disposal cell cap installed after remediation had been completed in 1990.

The large variability between the results of the two rounds of samples within the leachatecollection system is caused by the large seasonal variation in the water table elevations andgroundwater/surface water flow regime. This large variability between sample results collectedfrom the first and second rounds is also seen in many other groundwater samples collected.

7.7.2 Soil ContaminationThis section summarizes the nature and extent of contamination in the soils at the SRI site.Sixteen locations were sampled using hand auger samplers which were advanced to a maximumof 2 feet below grade to collect one shallow soil sample. Twenty-one hollow-stem auger soilboring locations were sampled using split-spoon samplers. Auger samples were collectedintermittently from surface grade to a maximum of 46 feet below ground surface, dependent onorganic vapors screening results and preassigned sample intervals. A total of 96 soil sampleswere collected at the SRI site as part of this RI.

The most frequently detected volatile organic found in the surface soil (0-3 foot depth interval)is acetone which was only detected in 8 out of 42 samples. Acetone concentrations in surface

EDIS/ENG/ay071494.rp7 7-2 , , , - , ,SLR-0010770

soils ranged from 5.5 pg/kg to 82 pg/kg which is less than the 200 pg/kg ARAR. The mostfrequently detected semivolatile compound found in surface soils is bis(2-ethylhexyl)phthalatewhich was detected in 22 of the 42 samples collected. These detected concentrations rangedfrom 34 pg/kg to 6,500 pg/kg, which is significantly below the proposed cleanup level of 46,000pg/kg presented in Table 4-16. The only constituent found in surface soils above these proposedcleanup levels which are based upon the most stringent guidance level is benzo(a)pyrene. Onlytwo samples contained this compound and the highest detected level found at SB-21 (within thegravel pit) is 73 pg/kg. Since the proposed cleanup criteria is 60 pg/kg this one sample is onlyslightly higher than the most stringent current regulation.

Arsenic was detected in almost all of the surface soil samples; however, values only ranged from0.7 mg/kg to 1.2 mg/kg. According to the January 1994 NYSDEC Technical AdministrativeGuidance memorandum (TAGM), background level for New York range from 3 to 12 mg/kg.These values are well below reported background levels for New York State.

The highest contaminant levels found in subsurface soils was from soil samples collected fromMW-05/MW-05A. The three highest samples from this boring, located adjacent to thenortheastern comer of the disposal cell were MW05-SS06, MW5A-SS07, and MW5A-SS08. Thefollowing analytical results were detected in these samples:

Arsenic was found in most other wells on-site at levels less than 10 pg/C, so elevated levels seemto be attributable to the former disposal cell. However, even though these levels are above theNYSDEC 1994 TAGM level of 25 pg/f, they are not significantly over the federal standard of50 pg/f. Even though manganese is slightly higher in the former disposal cell areas, it is alsofound in significant levels over the entire site indicating that the manganese is naturally occurringin the dolomite bedrock and glacial till and is a function of the geologic region and not pastdisposal practices.

The most predominant contaminants present in the overburden groundwater in the vicinity of theformer disposal cell area are VOCs (both chlorinated and nonchlorinated) and inorganic analytes,mainly arsenic and manganese. The overburden wells located furthest east (downgradient) of theformer disposal cell area (i.e., MW-08S, MW-07I, and DM-8S) are contaminated, primarily withVOCs and inorganics. Since there are no additional wells located immediately downgradient ofthese wells, it is not possible to fully delineate the extent of lateral contamination. It is verylikely that the contamination extends into the wetlands located immediately east of mis area. Thearea adjacent to the former disposal cell appears to be the only significant area of overburdengroundwater contamination at the SRI site. It appears that groundwater contamination from theformer disposal cell has migrated in an easterly direction with the local flow of overburdengroundwater in this area.

The only contamination present in the bedrock groundwater is localized in the area east of theformer disposal cell; in particular in well MW-07D (acetone, 280 pg/f). The other 7 on-sitebedrock wells did not contain any contaminants above State and federal standards. It is likelythat the contamination present in the overburden aquifer has migrated from the fluvial sands intothe dolomite bedrock. MW-07D is the only on-site bedrock well that does not contain a till layerseparating the fluvial sands from the bedrock.

Note:1 Lowest value may present a detection limit in some parameters.

Low concentrations of volatile organic, semivolatfle organic compounds, and pesticides weredetected in a limited number of residential wells. Not one volatile organic contaminant exceededguidance levels in the residential wells. Residential well HW-12 had the highest concentration(68 pg/f) of the semivolatile bis(2-ethylhexyl)phthalate. However, the second round of samplesfor HW-12 yielded a non-detected value for bis(2-emylhexyl)phthalate. The NYSDEC TAGMlevel is SO ug/C while the federal standard is 6 ug/f Bis(2-ethylhexyl)phthalate does not appearto be site related since only 15 of the 40 samples contained detectable levels of this compound.The highest onsite value was 33 ug/{ which is less than half of the level detected in HW-12.The NYSDOH collected a sample from HW-12 on August 9, 1993. Bis(2-ethylhexyl)phthalatewas not detected in this sample. Thus, the highest level of bis(2-ethylhexyl)phthalate detectedin residential wells was not confirmed by two additional rounds of sampling. Also, detectedlevels were sporadically found in on-site wells and were not clustered around the former disposalcell area. The only detection of PCB was found in residential well HW-14 at a level so closeto detection limits (0.4 ug/C) that it is questionable if this detection is valid. PCB was notdetected in the second round or in subsequent rounds of DOH sampling.

EDIS/ENG/ay071494.rp7 7-8SLR-0010776

Two inorganics found to exceed ARARs are lead and arsenic. The highest hit of lead on-site is25.5 pg/f which is approximately equal to the most stringent ARAR (25 pg/{). Also, thedetected levels were sporadically located throughout the site and were not clustered adjacent tothe former disposal cell. Since HW-04 detected a level of 61.4 ug/C which is more than twicethe highest value on-site, this contaminant does not appear to be site related.

Arsenic detected in HW-07 (37.2pg/l) may be caused by naturally occurring arsenic. Thisdetected value of arsenic at this distance from the site is not considered site-related since thereis no evidence of a direct exposure pathway. It should be noted that arsenic was non-detect inthe second round of sampling as well as subsequent DOH sampling. The high variabilitybetween sampling rounds found at the SRI site may be caused by the high fluctuation in thewater table and the dilution/concentration effects of seasonal variation. This high level ofseasonal fluctuation is common in this region.

7.7.4 Surface Water and SedimentA total of 18 locations were sampled for both surface water and sediment as part of this RI.Both filtered and unfiltered surface water samples were collected for inorganic analyses. Themain areas of focus of the surface water and sediment investigation were:

Northwestern Wetlands 2 WN-17 and WN-18Locations along Eastern 4 TS-01 through TS-04Tributary to Sucker Brookwhich Conducts WaterAway from the Site

Surface water organic contamination at the SRI site is minimal. Low concentrations of a fewvolatile and semivolatile organic compounds and pesticides were detected, primarily in the areaof the northwestern wetlands and the eastern tributary to Sucker Brook (see Section 4.4).

Similar to the surface water data, only low concentrations of a limited number of volatile andsemivolatile organic compounds and pesticides were detected in the sediment samples. Themajority of the volatile and semivolatile organic compounds were detected in the area east of theformer disposal cell area. The pesticides were primarily detected in the eastern wetlands,

EDIS/ENG/ay071494.rp7 7-9SLR-0010777

southeast of landspreading area M. The highest number of elevated inorganic analytes weredetected in samples collected east and downgradient of overland flow from the former disposalcell area.

7.2 Fate and TransportContaminants can be transported from their source(s) to other areas as a result of several potentialmigration pathways. Potential migration pathways for transport of contamination from the SRIsite include transport by wind, groundwater, surface water and sediment, and food chainbioaccumulation. These contaminant transport pathways provide a potential link between knownsources and potential receptors (Figure 7-1).

The transport of contaminants away from source areas is dependent on several factors. Theseinclude site characteristics such as geology (including soil and bedrock conditions); hydrology(including groundwater and surface water conditions); climatology (including precipitationconditions); and contaminant characteristics such as physical/chemical properties, chemicalconcentration, and chemical distribution. Since most of the contamination on-site is associatedwith groundwater, this transport pathway is the major pathway of concern at the SRI site.

7.2.1 Groundwater TransportRelease and transport to groundwater is the primary route and mechanism of on-site contaminantmigration for both dissolved inorganic and organic compounds detected at the SRI site. Oncea soluble-phase substance is in groundwater, it is transported in the direction of groundwaterflow. The topographic ridge (Figure 2-1) that is oriented in a south to north direction in thecenter of the site is the topographic expression of a similar ridge in the overburden and bedrock.The overburden ridge, which consists of nitrified drift and till deposits, is probably the primaryrecharge area for the site. Therefore, a groundwater divide in the overburden aquifer is foundbeneath the ridge. The predicted overburden groundwater flow direction to the east of the ridgein an east-southeast direction. Overburden groundwater flow direction to the west of the ridgeis toward the north and west. The predicted bedrock groundwater flow is in a east-northeasterlydirection across the disposal cell.

Based on the available vertical gradient and geologic information, there is the potential forhydraulic connection between the bedrock and the overburden formation. At places where thetill is present, the two formations may be hydraulically separated. However, near the edge of theeastern wetlands and at the MW-07 well grouping, the till is not present. In these areas the twoformations are probably hydraulically connected.

The wetlands area is an expression of both overburden and bedrock groundwater discharge aswell as stormwater runoff during wet seasons. As presented in Chapter 3.0, seasonal fluctuationcan cause extreme differences in water level elevations (from 4 to 15 feet) and groundwatercontaminant concentrations. The SRI site characteristics are typical of regional geology andhydrogeology and these types of seasonal fluctuations and hydraulic divides (hills and valleys)are common in this region.

Soluble chemical constituents that enter the groundwater are transported in the direction ofgroundwater flow. The rate of transport in the overburden aquifer is determined, in part, byequilibrium partitioning between the mobile aqueous phase and the stationary soil particles. Thedegree of partitioning is governed by the organic matter content of the soils.

Figure 7-2 presents a cross section of the disposal cell area with the VOC plume adjacent to thenortheast corner of the former disposal cell (approximately 15-25 feet bg). The VOCcontamination follows the top of the till and is concentrated in the bottom of the overburdenaquifer. Monitor wells MW-05S and MW-05I are the most contaminated wells. Thegroundwater found in the bedrock aquifer at MW-07D appears to be contaminated; however,groundwater found in the bedrock aquifer at MW-05D does not appear to be contaminated. Thetill unit pinches out as it approaches the eastern wetlands at MW-07 and has probably preventedthe underlying bedrock unit from becoming contaminated at MW-05. If the contamination hasreached the wetlands, it is only slightly evident in surface water and sediment stations WE-12through WE-16. Contamination has not reached the DM-9 well on the other side of the wetland(south east of the cell); thus, the edge of the contaminant plume must be located between MW-08S/MW-07I and DM-9 (potentially north of DM-9).

7.2.2 Groundwater Recharge to Surface WaterThe eastern tributary to Sucker Brook is located within the site boundary. Sucker Brook isdesignated a Class D water body by the State of New York (i.e., protection for fish survival).Sucker Brook flows norm, ultimately entering the St. Lawrence River near Waddington, NewYork. The headwaters to the tributary are formed by low lying wetlands located in the easternportion of the site. These waters are considered perennial and intermittent. The results of theSupplemental Phase I and Phase n investigation have determined that the overburden as well asthe bedrock aquifers are hydraulically connected to the surface water present in the wetlands.However, due to such seasonal variations in the groundwater table and the intermittent nature ofthe stream, the surface water can be an expression of groundwater discharge during wet periodswith a high groundwater table or the surface water runoff can recharge the overburden aquifer

during dry periods. The overburden groundwater recharge or discharge condition is highlydependent on the seasonal fluctuation of the water table.

7.3 Baseline Risk AssessmentBoth a human health and an ecological assessments were performed for the SRI site. The humanhealth risk assessment provides a conservative approach to approximating plausible exposurescenarios to potential receptors. The ecological assessment evaluates potential adverse impactsassociated with estimated exposure concentrations for selected ecological receptors.

7.3.1 Public Health EvaluationSeparate risk analyses were conducted for both current land-use and possible future land-use ofthe site. Samples were collected from all media of concern (i.e., surficial soil, groundwater,sediment, surface water) to quantify constituent concentrations. The resulting analytical datafrom remedial investigations conducted at the SRI site and vicinity in 1992 and 1993 were usedas the database for this risk assessment.

For this risk assessment, it was assumed that die same individual or subpopulation may beexposed to the constituents of concern via multiple pathways. Accordingly, the carcinogenicrisks and the non-carcinogenic hazards calculated are summed to provide an estimation of thetotal risk/hazard to the exposed populations from site-related constituents of concern from the SRIsite. Reasonable maximum exposure (RME) default parameters were employed for all potentialpathways to represent the most conservative estimate of potential exposure and, therefore, be themost health protective.

For any pathway that showed excessive risk/hazard using RME exposure parameters, thesepathways were re-evaluated using Central Tendency Analysis exposure parameters. CentralTendency Exposure (CTE) default parameters utilize average exposure frequencies and durationvalues rather than upperbound estimates for determining daily chronic intake of constituents inthe risk/hazard analyses.

7.3.1.1 Current Land UseThe SRI site has been abandoned for approximately 14 years, and extensive remediation measuresof the site have taken place within this time period. There is no work force on-site, and thecurrent on-site exposure pathways are limited to trespasser (adult, older children aged 6-12 yearsold) receptors. Older children were selected as a more conservative receptor population for thetrespasser scenarios, as this age group may explore the SRI site in this rural, sparsely populated

EDIS/ENG/ay071494.rp7 7-14SLR-0010782

area. There are no groundwater sources (e.g., active wells) on-site and groundwater was notconsidered an exposure medium for current land-use scenarios for the SRI site. Constituents inthe surficial soils, wetlands sediments, and seasonal-related intermittent surface water may behazardous to on-site trespassing receptors.

Based on analysis of identified surficial soil constituents of concern, six trespasser exposurepathways were quantified in this assessment for current on-site abandoned land use:

• Incidental ingestion of site soil;• Dermal absorption of constituents from site soil;• Incidental ingestion of on-site surface water,• Dermal absorption of constituents from surface water;• Incidental ingestion of on-site sediments;• Dermal absorption of constituents from sediments.

The total carcinogenic risk to an on-site trespasser from exposure to site-related constituents ofconcern is 1.44E-05 carcinogenic risk for adults and 1.22E-OS carcinogenic risk for children(Table 7-2). These risks are within the acceptable carcinogenic risk range of l.OE-04 to l.OE-06total carcinogenic risk. Dermal contact with on-site surface water contributed 63% of the totalcarcinogenic risk to trespassers. Pentachlorophenol contributed 94% of the total risk to currenton-site land use conditions.

The total non-carcinogenic hazard to an on-site trespasser from exposure to constituents ofconcern is 4.76E-02 hazard index for adults and 1.89E-01 hazard index for children. Thesehazard indices are below 1.0 and considered acceptable. Incidental ingestion of wetlandssediment contributed 47% of the total non-carcinogenic hazard, with arsenic contributing 99%of the non-carcinogenic risk of this medium.

7.3.1.2 Future Land UseThe on-site future residential use exposure assessments were based on current concentrations ofconstituents in on-site surficial soils, wetland sediments, surface water, and groundwater. Nineexposure pathways were quantified in this assessment for potential future residential land use ofthe SRI site. Five were residential exposure scenarios; four were related to play and recreationalactivities in the woodlands/wetlands of the site. These nine exposure scenarios were as follows:

• Ingestion of groundwater (potable well water);

• Dermal contact with groundwater (bathing, household uses of tap water);

• Inhalation of volatile COCs in groundwater by bathing and showering;

• Incidental ingestion of site soil;

• Dermal contact absorption of constituents from site soil;

• Incidental ingestion of on-site surface water through recreational activities;

• Dermal absorption of COCs from surface waters through recreational activities;

• Incidental ingestion of on-site sediments through recreational activities;

• Dermal contact absorption of COCs from sediments through recreational activities.

The total carcinogenic risk to residential adults and children based on future on-site residentialexposures has been calculated to be 2.34E-04 and 1.45E-04, respectively (Table 7-3).Groundwater is accountable for 89% of the carcinogenic risks to future on-site residentialpopulations. Arsenic was the major contributor to this calculated carcinogenic risk. Groundwateringestion was in exceedence of USEPA's risk guidance (1 x 10~* to 1 x 10"6).

In the future land-use scenario, the total non-carcinogenic hazard to adults and children in an on-site residential setting has been calculated to be 5.78E+02 and 1.34E+03, respectively. A totalof 99.9% of the non-carcinogenic hazard is attributed to use of groundwater from the compositedgroundwater aquifer. Acetone was the principal constituent of concern (COC) and accounts for99% of the non-carcinogenic hazard of this groundwater.

Ingestion of groundwater and dermal contact with groundwater were pathways that indicatedexcessive hazard (above 1.0). All other pathways for both children and adults had hazard indicesof less than unity.

7.3.2 Ecological Assessment EvaluationThe SRI site and the surrounding 0.5 mile radius area were investigated to determine existingecological conditions. All of the environs within the above mentioned study area werecharacterized and grouped into three habitat types: aquatic, wetlands and terrestrial. Observationsobtained during September 1992 field investigations were reviewed and species lists for avians(Table 6-15), mammals (Table 6-16) and vegetation (Table 6-17) were compiled.

Only one species listed within the New York Natural Heritage Program Database was observedwithin the study area. Clearweed (Pilea fontana) is a vegetative species typically found withinwetland habitats and was present on-site during September 1992 field investigation. Table 6-20and Table 6-21 present the New York Natural Heritage identified endangered/threatened speciesand significant habitat areas in the vicinity of SRI site, respectively.

Several individual great blue heron (Ardea herodias) were noted during field investigations. Thepresence of this species on-site may be a result of the heron rookeries which are listed as"Significant Habitat" by the New York Natural Heritage Program Database as existing in thevicinity of the SRI site.

Three target species namely, the raccoon (Procyon lotor), the American kestrel (Falco sparverius)and the meadow vole (Microtus sp.) were identified in order to calculate potential impacts toecological receptors as a result of the contamination present on-site.

Twenty-six constituents of ecologocal concern were identified and evaluated for potential impactsto the selected target species and aquatic biota in general. A comparison of the total daily intakeof the COECs for target species with the range of available toxicological data found in theliterature was the basis for the risk characterization. This assessment is more qualitative in naturedue to the limited availability of species-specific, chemical-specific and endpoint-specific data.The combination of these factors, therefore, contribute to the uncertainty of such comparisons.

Total daily intakes for each of the target species were calculated as a result of the ingestion ofsoil, sediment, surface water, vegetation and food. Species-specific dietary ingestion ratesobtained from the literature were used in these calculations.

Only two of the calculated TDE values for the target species exceeded appropriate NOAELs forany of the COECs for the SRI site. These are lead and di-n-butylphthalate. However, the di-n-butylphthalate exposure point concentration used to calculate the TDE values was based on highdetection limits for non-detects. Detected concentrations do not predict unacceptable TDE values.Lead exposure is high throughout the site. Though exposure to lead may have an effect, it isimportant to point out that effect are predicted from background levels also.

It is also important to note that the nature of some of the contamination at the SRI site may notbe solely attributed to previous site activities. The area surrounding the site has a large numberof farms. Some crops even exist in the northern area of the site. The pesticides used in

EDIS/ENG/ay071494.rp7 7-19SLR-0010787

maintaining the local farms could be transported to the SRI site via surface runoff or aerialdeposition. Some PAHs can also be attributed to such activities.

In conclusion, while the SRI site exhibits low levels of contamination, it does not pose anysignificant environmental hazard above that naturally occurs. Concentrations of most COECs areat levels such that target species would not receive constituents at levels known to cause harmto the individual animals. Overall, the ecology of the SRI site is typical for such a system. Thedata shows a low potential for future negative impacts from the identified COECs.

7.4 Data Limitations and Recommendations for Future WorkThe samples taken by IT during the field investigations for this RI report, were analyzed andvalidated by a USEPA CLP laboratory. These analyses were considered confinnational level,that is, the highest level of data quality. The analyses required full CLP analytical and validationprocedures, and were designed to be legally defensible.

The quantity estimates, results and conclusions presented in this RI report are based on this CLPvalidated analytical data. Data that were rejected in the validation process were not consideredwhen drawing conclusions about the nature and extent of the site contamination.

Data previously obtained by the NYSDEC, NYSDOH, Dames and Moore, SevensonEnvironmental Services and others were also considered in the preparation of this report. Whilethe chemical analyses presented in many of the previous studies may not have been performedto the same QA/QC standards as the samples taken for this RI report; nevertheless, the previousbody of existing data could not be ignored in attempting to define the contamination in the soiland groundwater of the site. While the previous investigations provided significant assistance,the location of contamination and its fate are fully supported by the USEPA and the IT validatedanalytical data.

The soils investigation adequately characterized the source of contamination (i.e., the disposalcell soils) as well as the nature and extent of contamination found in the soil media. Thegroundwater plume originating from the site has been partially defined via isopleths. The fartheston-site monitoring well cluster MW-07D and MW-07I contained contaminated groundwater; thusthe extent of the Sealand groundwater plume has not been clearly delineated in either the verticalor horizontal directions. DM-9, MW-04 and MW-06 wells contained relatively cleangroundwater samples; however, a finer delineation of the extent of the overburden/bedrock plumeis recommended prior to further remedial action.

EDIS/ENG/ay071494jp7 7-20SLR-0010788

The additional data requirements necessary to fully characterize the overburden and bedrockgroundwater flow regime and contaminant plume boundaries are as follows:

• Additional clustered monitoring wells to the east of the disposal cell between theMW-07/DM-8 wells and the surface water/sediment sampling locations WE-14 throughWE-15 in order to vertically and horizontally delineate the groundwater plume.

• Two additional wells at MW-08S to investigate the stratification of the overburden/bedrock plume.

• Pump tests to determine hydraulic characteristics of the aquifer.

• Additional quarterly sampling and water level measurements to investigate seasonalvariation to determine the effect of stonnwater/surface water infiltration/discharge onlocal groundwater hydraulics.

The data requirements should be fulfilled prior to or in conjunction with a design phase.

7.5 Recommended Remedial Action ObjectivesBased on evaluation of the chemical data and its associated risks, the following remedial actionobjectives have been developed.

1) Minimize migration of contaminated groundwater; and

2) Restore the groundwater quality currently being degraded as a result of the SRI site.
