SECTION 1.0EXECUTIVE SUMMARY
This report addendum documents the activities and findings of field investigations
conducted at the Hazardous Waste Storage Area (HWSA) at Rickenbacker Air
National Guard Base (the Base) during October of 1991. The purpose of this
investigation is to determine the extent of chemical contamination in the surface
sediment, soil and groundwater at the HWSA.
Previous investigations at this site are described in a report by Engineering-Science,
Inc. titled "Pre-Closure Sampling Report, Hazardous Waste Storage Area" (draft,
October 1990).
Rickenbacker ANGB is located twelve miles southeast of Columbus, Ohio. The
facility has been in operation since the early 1940s in support of training and air-to-airI refueling missions.
The HWSA at the Base consists of Building 560 and the Drum Storage Area
southeast of the building. It has been under a Part A Permit for hazardous wastestorage since 1983. The facility was last used in September 1986. The Drum Storage
Area adjacent to Building 560 had been used to store liquid wastes such as spent
solvents, cleaning fluids, acids and paint strippers. There are four 25,000-gallon steel
underground storage tanks (USTs) adjacent to the HWSA. One tank is situated within
the area defined by the perimeter fence. The USTs have been in use for approximately40 years. Two tanks currently store de-icing fluid. JP-4 jet fuel, and recyclable oil were
historically stored in the other two tanks.
Activities conducted during the pre-closure sampling included surface soil sampling,
shallow and deep soil sampling by boring, installation of groundwater monitoring wells
and groundwater sampling.
All work conducted at the HWSA was done in accordance to the Pre-Closure
Sampling Plan (December 1989, Addended September 1991) with site activities being
complete in the Spring of 1990 and in October 1991.
I1M 9PC1t436W$ 1-1
The surficial (<30' below grade) unconsolidated materials are similar throughout
the Base and the HWSA. The uppermost ten feet is typically a brown silty clay, with
trace amounts of small pebbles. From ten to approximately fifteen feet is silty/sandy
clay. A saturated sand is encountered at approximately 15 feet. Water from this sandrises in wells to eight to ten feet below grade. This is underlain by a thin (<1') layer of
hard, dense gray clay over brown to gray sand and gravel. The hydraulic gradient is in ageneral southerly direction.
The investigation conducted in 1990 determined that the surface and shallow soil
within and adjacent to the HWSA are contaminated with metals, semi-volatile organiccompounds (SVOCs) and volatile organic compounds (VOCs). The extent andconcentration of contaminants generally decrease with depth. The exception to thatgeneralization is the contamination of the shallow aquifer with phase-separatedhydrocarbons, dissolved fuel components and halogenated VOCs with only trace
concentrations in the shallow soil. In 1991, additional investigations were conducted todetermine the extent of contamination.
The investigation conducted in 1991 defined the extent of the contaminants at thissite. Groundwater screening, soil boring and sampling, monitoring well installation,surface soil sampling and groundwater sampling were conducted during October of 1991
that assisted in defining the contaminant plume. The downgradient extent of thegroundwater is defined by monitoring wells (MW) 11 and 12 which are approximately120 feet downgradient from the southeastern corner of the HWSA.
Groundwater samples obtained from existing wells at the site confirmed existence ofVOCs previously detected in samples taken from these wells. Phase-separatedhydrocarbon (PSH) was apparent in MW1 and MW5 during the 1991 investigation("Determination of Phase-Separated Hydrocarbon Extent at the Hazardous Waste
Storage Area", draft, October 1990, ES). Well MW5 had previously exhibited the
existence of PSH.
Recovery of PSH has been ongoing at MW5. Limited amounts have been recoveredtotalling less than 55 gallons. The extent of PSH in the groundwater was explored using
the groundwater screening tool. The total extent of PSH is limited to the areaimmediately surrounding MW1 and MW5. The source or origin of the hydrocarbon isunclear.
0192EPI.M#WS 1.2
These data as well as all other data obtained at the HWSA will be incorporated into
a Closure Plan for the proposed closure of this permitted storage area. This ClosurePlan will be reviewed by the Ohio Environmental Protection Agency. It is anticipatedthat groundwater cleanup will be undertaken during the closure of this site.

SECTION 2.0
PURPOSE AND SCOPE
This addendum documents the activities and findings of the field investigations
conducted in October 1991 at the former Hazardous Waste Storage Area (HWSA),
building 560, at Rickenbacker ANGB, Ohio (Figures 1 and 2). These investigationswere conducted in accordance with the Pre-Closure Sampling Plan (PSP) dated
December 1989 and the Addendum #1 to the PSP dated September 1991. The data
collected during this investigation will be appended to the existing database for this site.Reporting of data from the original investigation was completed in the "Pre-ClosureSampling Report, Hazardous Waste Storage Area", draft, October 1990 by Engineering-Science (ES). All data obtained from this site will be used for the completion of aClosure Plan for this HWSA.
The additional sampling described in this addendum was conducted to fill data gapsexisting after the original pre-closure sampling report. Specifically, these data gaps are:
The anomalously high concentrations of semi-volatile organic compounds(SVOCs) found at the surface soils of the westernmost corner of the HWSA.
* The extent of VOCs previously detected in the groundwater. The findings of thisinvestigation define the extent of the contaminants from this HWSA.

BACKGROUND
The Rickenbacker Air National Guard Base (the Base) is located 12 miles southeast
of Columbus, Ohio, and one half mile east of the Village of Lockbourne (Figure 1). Thefacility has been in use as an air field since 1942 when it was activated as theNortheastern Training Center of the Army Air Corps. Portions of the facility are
currently under ownership of the Rickenbacker Port Authority (RPA).
The former HWSA at the Base consists of Building 560 and the fenced in drum
storage area southeast of the building. The site is under a Part A Permit for the storageof hazardous wastes, and was used to store drummed wastes from the Base from 1983until September 1986. Materials that were stored here were spent solvents, cleaning
fluids, acids, paint strippers, and spent desicc-" its. Four 25,000-gallon undergroundstorage tanks (USTs) are located in the southeastern comer of the drum storage areas.
One of the USTs is situated within the area defined by the perimeter fence of the drum
storage area. The USTs are not described by the Part A Permit, and were not used to
store hazardous waste. Two of the tanks have been used to store de-icing fluid, one tank
for recyclable JP-4 jet fuel, and one tank for the storage of recyclable oil.

I FIELD INVESTIGATION PROGRAM
3 Field activities conducted during this investigation include groundwater screening,
monitoring well installation and soil sampling from the well borings, surface soilu sampling, and groundwater sampling.
4.1 Groundwater Screening
A groundwater screening survey was conducted on 7 through 9 October 1991 to
determine the extent of volatile organic compound (VOC) contamination previously
detected in the groundwater at the HWSA. Groundwater screening samples were
collected from the shallow aquifer, approximately 15 to 20 feet below grade, at eighteenlocations on and around the HWSA using a GEOPROBETm system. Locations of the
screening points and the results of the analysis are contained on Figure 3.IThe PSP proposed 24 groundwater sampling points. These would be installed
downgradient (south and east) of the known contamination, and in the immediate
vicinity of MW5.
U The purpose of this sampling was twofold. The initial interest is to identify the
extent of the contaminant plume and locate downgradient wells outside of the plume.The second interest is to further characterize the extent of phase-separated hydrocarbon
(PSH) in the vicinity of MW5.
The GEOPROBE m system utilizes a hydraulic hammer to drive a 3/4-inch, outer-
diameter, steel probe to the water table. These probes have a 3/8-inch lumen and come
in 3-foot sections which thread together. The downhole end of the probe is fitted with a
stainless-steel, right-circular conical, sacrificial drive point. Upon reaching the desired
_ depth of sample, the probe is extracted approximately six inches causing separation of
the drive point and allowing groundwater to flow into the probe lumen. The
groundwater screening sample is extracted from the probe using a clean TeflonTm tube
equipped with a stainless steel check ball. The tube is surged inside the probe to
enhance sample recovery. Typical sample recovery is 100 to 200 milliliters of water.
The groundwater screening sample is then decanted directly from the Teflon Tm tube into
a standard 40 milliliter vial until the vial is half full, approximately 20 milliliters.

IDuplicate screening samples in the ratio of one for every ten total samples are also
collected.
The headspace of the vial was analyzed immediately on site in a Hewlett-Packard
5890A Series I1 gas chromatograph equipped with a flame ionization detector. The
method of analysis used is a modified United States (US) Environmental Protection
Agency (EPA) Method 601/602. The analytical process takes approximately one-halfhour per sample and is capable of detecting calibrated compounds of 1 microgram per
liter (Ag/L) or greater. The chromatograph was calibrated specifically for analysis of
the headspace vapor.
U The results of the groundwater screening technique allow for rapid delineation of
extent of target compounds in groundwater. The target compounds used in this survey
I include benzene, toluene, ethylbenzene, xylenes, and trichloroethylene which had been
detected in groundwater samples from existing monitoring wells at this site.IDecontamination procedures for the probes comply with those outlined in the PSP.
Used TeflonTh tubing was discarded, and new tubing was used for each sample.
4.2 Monitoring Well Installation
Three monitoring wells were sited and drilled based on the results of the
groundwater screening. These wells were drilled, sampled and constructed in
accordance with the procedures outlined in the PSP. Locations of these wells are
identified on Figure 3 of this report. Soil samples were obtained for analysis during the
boring of these monitoring wells. Boring logs and monitoring well construction logs arecontained in Appendix A of this report.
The wells were located in areas downgradient of the known contaminant plume
adjacent to groundwater screening locations which had not indicated detectable target
VOCs. The PSP proposed the installation of six monitoring wells. Three wells were
omitted because the plume was not as extensive as described in the PSP, and there was
no indication of groundwater contamination near the three USTs northeast of the site.

- 4.3 Surface Soil Sampling
Surface soil samples were collected from ten locations near the westernmost comer
of the HWSA. Procedures used to collect these samples comply with those described in
the PSP. One duplicate soil sample (SS 3 DUP) was also obtained.
The surface soil sampling locations were changed from the locations suggested in
I the PSP based on several factors which include accessibility, ease of sample recovery,
and apparent use of the neighboring property. The neighboring property is used for
_ salvage storage and is paved which would make sampling with a trowel difficult. The
neighboring property was also under construction at the time of sampling further
complicating access. The ten suggested sampling locations were changed at the requestof the field team leader and approved by A. Harlick and T. Shope of HAZWRAP on 9
October 1991. The ten locations were evenly distributed between the HWSA fenceline
and the fenceline associated with the neighboring property. the representatives of theOEPA were made aware of the field change the day of sampling.
4.4 Groundwater Sampling
-U Groundwater samples were collected from ten of the 12 wells on site. Wells MW1
and MW5 were not sampled due to measurable thicknesses of phase-separated
I hydrocarbons. Sample recovery from wells MW3, MW8, and MW9 were limited to
VOCs because of poor groundwater recharge. Complete aliquots were collected from
each of the other wells on site. The groundwater sampling was carried out in
accordance with the procedures outlined in the PSP.

I FIELD INVESTIGATION FINDINGS
5.1 Groundwater Results
The data obtained through the groundwater screening and groundwater sampling
were plotted on a map of the site (see Figure 3). The data indicate that VOCcontamination is restricted to a relatively small area surrounding the four underground
storage tanks (USTs) located at the southernmost comer of the site. Wells MW1 and
MW5, where phase-separated hydrocarbons were observed, lie in the northern and
furthest upgradient portion of this contaminant plume. The groundwater sampling data
plotted in Figure 3 are also presented on Table 1. The downgradient edge of the VOCplume is well documented by the non-detect analyses of wells MW10, MW11, and
MW12.
Groundwater analysis from the October 1991 field effort duplicated groundwateranalysis from February 1990 for MW2 through MW8. The 1991 analysis indicated non-
detectable VOCs in MW4, MW9, MW10, MW1, and MW12. The 1990 analysis
indicated similar data for MW2, MW4 and MW9. Table 1 contains results from boththe 1990 and 1991 sampling events.
5.2 Soil Results
I Surface soil samples were collected at ten locations near the westernmost corner ofthe HWSA. Five of these samples were collected at the fenceline surrounding the site,
-- the remaining five from locations off site. One sample (SS3) was collected in duplicate.All surface soil samples were analyzed for SVOCs and the priority pollutant metals. Soil
samples were also obtained from two soil horizons during the boring of the three
monitoring wells.
- Results of the SVOC analyses were tabulated and totaled by sampling location.
These totalled data are plotted on Figure 4 of this report and tabulated on Table 2. The
higher concentrations of total SVOCs are associated with four of the five surface soilsamples collected outside the HWSA compound.

These surface soil data, when related to existing semi-volatile data, indicate that thecontamination in the area of SS5, SS6, and SSIO appear to be from within the HWSA.
The contaminants detected in SS3, SS4, SS8 and SS9 appear to be unrelated to thisHWSA since no SVOCs were detected in samples SS2 and SS1.
The soil samples from the well borings indicate levels of his (2-ethylhexyl) phthalatefrom 120J to 440 in each of the samples. This compound was not detected in other
subsurface soil samples. Although it does not appear to be a laboratory contaminantbased upon the data validation notes contained in Appendix B of this report, due to theuniform distribution at which the compound was reported, and that the compound wasnot reported at the site previously, and that the compound was not reported in anygroundwater samples, it may be suggested that his (2-ethylhexyl) phthalate wasintroduced into the samples from an unknown source, and is not an actual contaminant
at the site.
Soil sample MW12 (13-15) was obtained from the well boring for MW12 from thesoil interval from 13-15 feet below grade. The analytical results (Table 2) from thissample indicate several SVOCs. None of these compounds was detected in thegroundwater sample from this well. It may be assumed that these data are the result of
a naturally occurring anomalous organic matter in the soil at that location.
Results of priority pollutant metals analyses of the shallow soils indicate the
presence of several metals above the Base background established during theInstallation Restoration Program investigation. The metals arsenic, cadmium, lead, zinc
and to a limited extent copper, nickel and silver are found in concentrations in excess ofbackground levels. Table 3 tabulates these data.
5.3 Hydrogeology
The three well borings advanced at the site during this field investigation,
encountered materials of similar description to those seen previously at this site.
Soil from the ground surface down to eight feet is characterized by a medium brown
silty clay, with trace amounts of pebbles. This layer grades into a grayish silty clay fromeight to 14 feet, with moisture encountered at ten feet. Further description of soil andgroundwater is contained in the Pre-Closure Sampling Report, draft, October 1990.

I Water levels in all 12 wells at this site were monitored on 17 October 1991. The
groundwater elevation map generated using this data is illustrated on Figure 5 and
tabulated on Table 4. It confirms groundwater flow to the southeast, and a slight rising
of groundwater potentiometric surface near the USTs.
Wells MW3, MW8 and MW9 exhibited poor recharge during purging and sampling
perhaps indicating severe impact from the dry summer preceding the investigation.According to the Monthly Water Inventory Report for Ohio which is published by the
Ohio Department of Natural Resources, Division of Water, rainfall from May through
October of 1991 was 7.68 inches below normal for the Columbus area.

SECTION 6.0
I CONCLUSIONS AND RECOMMENDATIONS
6.1 Conclusions
The analytical results indicate soil contamination in throughout the HWSA down todepths of over fifteen feet, as well as contamination of the groundwater with organic
solvents and fuel components. Consequently, removal of all of the contamination, toeffect a clean closure is not a practical option. The extent of contaminants at the HWSA
has been defined, and a closure plan will be compiled for review and approval by the
Ohio EPA.
6.2 Recommendations
I An appropriate remediation method would initiate a groundwater cleanup
engineered to remove contaminants from the groundwater at the site. The surface soilswould remain in place during this operation. When groundwater quality is deemed to beacceptable, determination of status of the soils would be determined. Further
evaluation of the risk to human health and the environment may be necessary duringthis final evaluation. Removal of the USTs at the HWSA is fundamental to instituting
* cleanup of this site.

APPENDIX BANALYTICAL DATA VALIDATION NOTES
This appendix presents a summary and review of quality assurance and quality
control results for the laboratory analysis of H20 and soil samples collected during 1991
phase of the site investigation at Rickenbacker Air National Guard Base (the Base) in
Columbus, Ohio. The analyses were performed by Engineering-Science (ES) Berkeley
Laboratory (BL).
The results from ESBL are divided into data packages which are assigned a work
order (WO) number. Each package contains the required quality control
documentation. Contract Laboratory Protocol (CLP) methods were required at the
time of these analyses according to "CLP Laboratory Data Validation EPA Functional
Guidelines for Evaluating Organics and Inorganic Analyses."
Each package was validated by reviewing holding times, method blanks, matrix
spike/matrix spike duplicates and field quality control samples. If the criteria as
specified by the EPA guidelines were not met, action was taken to indicate the
discrepancy. Validation notes will be "flagged" concerning any non-compliance to CLP
protocol.
The analytical results of the environmental and quality control samples were
evaluated to assess the representativeness, precision and accuracy, comparability and
completeness of the data. Representativeness was evaluated from the analytical results
of the trip blanks, field blanks, rinseate blanks, method blanks and field duplicate
samples. Precision and accuracy were evaluated by reviewing the laboratory matrix
spike sample (MS), and the matrix spike duplicate sample (MSD). The comparabilitywas evaluated by reviewing duplicate sample results. The completeness was evaluated
by reviewing the chain-of-custody with results.
All samples were analyzed within EPA data validation technical holding times.
Holding times are designated periods by EPA from sampling date to time of analysis.
Data Validation Flags - The following exceptions were outside the CLP acceptance
criteria and were acknowledged, or flagged accordingly. Data contained in Appendix C
of this report, reflect all validation notes.
I92DPC/-.2#WS .1-
In the Method Blank (MSBNA911023) and ES Samples SS4 (3377-04), SS6 (3377-
06), SS9 (3377-07) and 12-3-5 (3377-13), internal standard recoveries failed to meet
acceptance criteria. Analysis of a second aliquot of these samples were conducted and
gave similar results, indicating a possible matrix effect. The results of both analytical
runs are presented; "RA" is appended to the sample identifiers for the second run.
Sample 11-13-15 Matrix Spike (MS) (3377-12MS) showed percent recoveries for n-
nitroso-di-n-propylamine, 1,2,4-trichlorobenzene and pentachlorophenol that were
below acceptance criteria. The Relative Percent Differences (RPD) for 1,2,4-
trichlorobenzene acenaphthene and pentachlorophenol were above acceptance criteria.Analysis of a blank spike indicated the laboratory was in control with respect to these
compounds.
Samples 10-13-15 (3377-10), 12-3-5 (3377-13), and 12-13-15 (3377-14), internal
standard recoveries failed to meet acceptance criteria. Analyses of a second aliquot of
these samples were conducted and gave similar results, indicating a possible matrixeffect. The results of both analytical runs are presented; "RA" is appended to the
sample identifiers for the second run.
Sample 12-13-15 (3377-14) showed high surrogate recovery of two out of three
surrogates. Re-analysis produced acceptance results.
Preparation blanks and all Quality Control (QC) samples were analyzed using both
Inductively Coupled Plasa (ICP) and Graphite Furnace Atomic Absorption (GFAA)methods, resulting in two sets of QC data (one by ICP, one by GFAA) for lead. Allblank results which fall between the ICP Instrument Detection Limit (IDL) and five
times the ICP IDL of lead are flagged with "Y". The GFAA lead results for sample 11-13 is the valid result for that sample. The ICP lead result for this sample is for QCpurposes only.
The serial dilution sample result for zinc did not agree with the undiluted sampleresult for zinc within 10 percent, and the zinc result of the undiluted sample was greater
than 50 times the zinc IDL All zinc results in this batch are therefore flagged with "E".
Some analytical spike recoveries of selenium and thallium were less than 40 percent.These samples were diluted and re-analyzed; analytical spike recoveries were still less
than 40 percent. These selenium and thallium results are flagged with "E".
o192DPC/123.2S#ws .2.
I
In the method blank (MSBN911022) internal standard recoveries failed to meet
acceptance criteria. Analysis of a second aliquot of this sample was conducted and gave
similar results. All associated data were closely inspected. The laboratory has
determined this non-conformance to be an isolated occurrence. The results of both
analytical runs are presented; "RA" is appended to the sample identifiers for the second
un. Sample MW6 (3389-06) showed two surrogates in the base neutral fraction below
acceptance criteria. Re-extraction and re-analysis showed one surrogate above
acceptance criteria. The results of both analytical runs are presented; "RE" is appendedto the sample identifiers for the second run. All target analytes were undetected in
* either of the two analyses.
Sample MW3 (3389-01) showed high surrogate recoveries. Re-analysis gave similarresults, indicating a possible matrix effect. The results of both analytical runs are
presented; "RE" is appended to the sample identifiers for the second run.
