EXECUTIVE SUMMARY

The St. Isidore Landfill Site is located on Lot 3, Concession XV in the former Township of South Plantagenet, Ontario (now Nation Municipality). The site is located along Concession Road 16, approximately 3 kilometres north of the Village of St. Isidore de Prescott. The waste disposal area is located on a 2 hectare area. The total site area includes an 8.1 hectare buffer zone and a groundwater easement attenuation zone of 20.2 hectares. The landfill reached capacity in 1998 and was closed in the summer of 1999.

The objectives of the 1999 groundwater and surface water monitoring program were to monitor background water quality; water quality within the area impacted by landfill leachate; and water quality within the groundwater easement attenuation zone.

Based on the results of the 1999 groundwater monitoring program, it is confirmed that chloride, sodium, boron and TDS are significantly elevated in the background monitors within the silty clay deposit at this site and thus are less useful for assessing impacts from the landfill on groundwater quality. Based on the existing groundwater quality database, it is interpreted at this time that sulphate appears to be the most useful landfill leachate indicator parameters at this site. As such, the position of the leading edge of the landfill leachate groundwater plume has been inferred based on the sulphate concentrations in groundwater. It appears that the groundwater plume emanating from the landfill site is located within the boundary of the buffer and attenuation zone and therefore the site is in compliance with MOE Guideline B-7.

Additional seasonal surface water quality data are required to conduct a meaningful surface water compliance assessment.

The scope of the 2000 groundwater and surface water monitoring program is summarized in Sections 6.2 and 6.3 of the Stantec Consulting Ltd. January 2000 report entitled Nation Municipality, St. Isidore Landfill, Supporting Documentation to Application to Amend Certificate of Approval A471802 (the "January 2000 report"). This January 2000 report was submitted to the Ministry of Environment (the "MOE) in January 2000 in support of the application to amend the Certificate of Approval to reflect the closure of the landfill site during 1999. The results of the 2000 monitoring program at the St. Isidore Landfill Site are to be reported to the MOE on an annual basis as per Section 6.6 of the January 2000 report.

1.0 INTRODUCTION

The St. Isidore Landfill Site is located on Lot 3, Concession XV in the former Township of

South Plantagenet, Ontario (now Nation Municipality). The site is located along Concession

Road 16, approximately 3 kilometres north of the Village of St. Isidore de Prescott (Figure I).

The landfill reached capacity in 1998 and was closed in the summer of 1999. In January 2000,

the Nation Municipality submitted an application to the Ministry of Environment (MOE) to

amend Certificate of Approval No. 1471802 in order to designate the site as a closed landfill.

The waste disposal area is located on a 2 hectare area. The total site area includes an 8.1 hectare

buffer zone and a groundwater easement attenuation zone of 20.2 hectares (see Site Plan -

Figure 2).

The objectives of the 1999 groundwater and surface water monitoring program were to monitor

background water quality; water quality within the area impacted by landfill leachate; and water

quality within the groundwater easement attenuation zone.

This report discusses the results of the spring and fall 1999 groundwater and surface water

monitoring program and provides an assessment of the site with respect to compliance with the

MOE Guideline B-7 for groundwater (MOEE, 1994b) and with the requirements of the

Provincial Water Quality Objectives (PWQO) for surface water (MOEE, 1994~). A proposed

monitoring program for 2000 is also presented.

This report should be used in conjunction with the previous reports prepared by Golder

Associates (see reference list following the text of this report).

May 2000 - 2 - 991-2818

2.0 GEOLOGICAL SETTING

This section provides a brief summary of the geological setting of the landfill site based on the

data available from boreholes drilled and sampled during the previous site investigations. The

logs for the boreholes drilled during the 1991, 1994 and 1997 investigations undertaken by

Golder Associates are provided in Appendix C.

A silty sand layer with a relatively thin upper layer of topsoil (generally 20 centimetres thick)

overlaying a silty clay bed characterizes the geological conditions at the site. The thick

underlying silty clay bed is interpreted to be Champlain Sea clay. A sandy silt interbed is found

within the silty clay layer at the north-northeast toe of the landfill and is continuous towards the

north and north-northeast. This interbed increases in thickness towards the north and north-

northeast. At boreholes 94-8 and 94-9, situated near the toe of the landfill, this interbed is

approximately 1 metre thick. The interbed increases to 2.75 metres in borehole 97-14, at the

north-east boundary of the attenuation zone, and to at least 1.80 metres in borehole 97-15, at the

north boundary of the attenuation zone.

The silty clay layer was encountered at all borehole locations and is typically grey in colour and

contains silt and fine sand seams. At some locations, the upper part of the silty clay is weathered

to a grey brown colour. At borehole 91-1, the silty clay is at least 16.7 metres thick.

At this site, the surficial silty sand and sandy silt above the vertically extensive grey clay deposit

are collectively referred to in this report as the "surficial sand layer".

3.0 PHYSICAL HYDROGEOLOGY

The groundwater elevation data obtained during the spring and fall sessions of the 1999

monitoring program are summarized in Table 1.

The groundwater levels for the fall session were up to 1.26 metres lower than the spring session.

The direction of shallow groundwater flow is interpreted to be from the landfilled area toward

the northlnortheast as shown on Figure 2. This interpretation of the shallow groundwater flow

direction is consistent for the spring and fall monitoring sessions. Golder Associates (Golder

Associates, 1992; Golder Associates, 1995; Golder Associates, 1996; Golder Associates, 1997)

have previously recorded similar shallow groundwater flow patterns at the site.

May 2000 - 4 - 991-2818

4.0 FIELD PROGRAM

4.1 Spring 1999 Field Program

The spring 1999 groundwater and surface water monitoring program was undertaken on May 6"

and 7", 1999. The program included; locating and uncovering previously buried groundwater

monitors BH94-9 and BH94-10; measurement of groundwater levels and the collection of

groundwater samples from existing available monitors; and the establishment of surface water

monitoring stations and sampling of surface water.

During the previous investigation activities conducted in 1996, the monitors in boreholes 94-9,

94-10, 96-1 1 and 96-12 were modified so that they would not interfere with the operation of farm

equipment on the field. The monitors at these locations could not be located during the June

1997 testing program. The monitors 94-9 and 94-10 were located, uncovered and sampled for

the spring and fall 1999 monitoring programs. The monitors in borehole 96-1 1 and 96-12 could

not be located. In addition, the groundwater monitoring wells 91-1 and 91-2 were previously

determined to have been destroyed as a result of waste disposal activities at the site.

4.1.1 Groundwater Component

The groundwater monitoring session was carried out on May 6", 1999 and May 7th, 1999.

During the monitoring session, groundwater levels were measured in all accessible monitors.

The groundwater monitors which were to be included in the groundwater monitoring program,

along with the rationale for their inclusion, are described below;

surficial sand layer 97-16C To monitor background groundwater quality within the

siltv clav de~os i t

To monitor groundwater quality immediately downgradient of the waste disposal site

91-3,91-4,91-5

--

To monitor groundwater quality in the surficial sand layer ("B" wells) and the silty clay granular interbed ("A" wells) downgradient of the waste disposal site and at the ~ e r i ~ h e r v of the Leachate Attenuation Zone

To monitor landfill leachate impacts on groundwater quality immediately adjacent to the waste disposal site

May 2000 - 5 - 991-2818

The monitoring wells were typically developed through the removal of at least three standing

volumes of water using the dedicated samplers. Sampling of groundwater was performed the day

of the well development.

One blank sample was prepared using distilled water during the groundwater monitoring session

as part of the project Quality Control/Quality Assurance (QAJQC) program. The temperature,

pH and conductivity of the groundwater samples were measured in the field at the time of sample

collection. The field conductivity measurements were obtained using a Myron L Conductivity

Meter Model EP that was calibrated in the field prior to use. All samples were entered on a

Chain of Custody form and placed in coolers with ice packs until they were delivered in person

to the private analytical laboratory. Groundwater samples were collected, prepared and

preserved in the field as follows;

a One 1000 millilitre plastic bottle, unfiltered and unpreserved for alkalinity, total dissolved

solids (TDS), chloride, nitrate, nitrite, ortho-phosphate and sulphate.

a One 250 millilitre plastic bottle, field filtered to 0.45 microns and preserved to pHc2 with

nitric acid for the following metals; calcium, magnesium, sodium, potassium, aluminum,

barium, beryllium, boron, cadmium, chromium, cobalt, copper, iron, lead, manganese,

molybdenum, nickel, total phosphorous, silicon, silver, strontium, sulphur, thallium,

titanium, vanadium, and zinc.

One 250 millilitre amber glass bottle with foil lined cap, unfiltered and preserved to pH<4

with phosphoric acid and copper sulphate for analysis of phenols

a One 250 millilitre plastic bottle, unfiltered and preserved to pH<2 with sulphuric acid for

analysis of ammonia, dissolved organic carbon (DOC), and chemical oxygen demand (COD)

Accutest Laboratories Ltd. in Nepean, Ontario, performed all laboratory chemical and physical

analyses on groundwater samples. The Report of Analyses from Accutest Laboratories Ltd. For

the spring session are provided in Appendix A-1.

May 2000 - 6 - 991-2818

4.1.2 Surface Water Component

The surface water monitoring session was performed at the site on May 7", 1999. The surface

water stations that were included in the spring monitoring session, along with the rationale for

their inclusion, are provided below:

The locations of the surface water stations are shown on Figure 2.

The temperature, pH, dissolved oxygen (DO) and conductivity of the surface water samples were

measured in the field at the time of the sample collection. All samples were entered on a Chain

of Custody form and placed in coolers with ice packs until they were delivered in person to the

private analytical laboratory. The surface water samples were collected, prepared and preserved

in the field as follows;

One 1000 millilitre plastic bottle, unfiltered and unpreserved for alkalinity, total dissolved

solids (TDS), chloride, nitrate, nitrite, ortho-phosphate and sulphate

One 250 millilitre plastic bottle, unfiltered and preserved to pH<2 with nitric acid for the

following metals; calcium, magnesium, sodium, potassium, barium, beryllium, boron,

cadmium, chromium, cobalt, copper, iron, lead, manganese, molybdenum, nickel, total

phosphorous, silicon, silver, strontium, sulphur, thallium, titanium, vanadium, zinc and tin

Accutest Laboratories Ltd. in Nepean, Ontario, performed all laboratory physical and chemical

analyses on surface water samples. The Report of Analyses from Accutest Laboratories Ltd. For

the spring session are provided in Appendix A-1.

4.2 Fall 1999 Field Program

The fall 1999 groundwater and surface water monitoring program was performed on October 12"

and 13", 1999. The program included; excavation of buried groundwater monitoring wells;

measurement of groundwater levels; collection of groundwater samples from available monitors;

and sampling of surface water. During the monitoring program, the surface water monitoring

stations SW-1 and SW-2 were dry. The groundwater monitoring wells 94-8B and 97-13B were

found to be dry as well. The monitors in boreholes 96-1 1 and 96-12 could not be located and

therefore were not sampled.

4.2.1 Groundwater Component

The groundwater monitoring session was carried out on October 12" and 13", 1999. During the

monitoring session, groundwater levels were measured in all accessible monitors. The

groundwater monitors which were to be included in the groundwater monitoring program, along

with the rationale of their inclusion, are described below;

The monitoring wells were typically developed through the removal of at least three standing

volumes of water using the dedicated samplers. Sampling of groundwater was performed the day

of the well development.

One blank sample was prepared using distilled water during the groundwater monitoring session

as part of the project Quality ControlIQuality Assurance (QAIQC) program. The temperature,

pH and conductivity of the groundwater samples were measured in the field at the time of sample

collection. The field conductivity measurements were obtained using a Myron L Conductivity

Meter Model EP that was calibrated in the field prior to use. All samples were entered on a

Chain of Custody form and placed in coolers with ice packs until they were delivered in person

to the private analytical laboratory. Groundwater samples were collected, prepared and

preserved in the field using the same protocol followed during the spring monitoring session

(refer to Section 4.1.1).

Accutest Laboratories Ltd. in Nepean, Ontario, performed all laboratory chemical and physical

analyses on groundwater samples. The Report of Analyses from Accutest Laboratories Ltd. for

the fall session are provided in Appendix A-2.

4.2.2 Surface Water Component

An attempt was made to sample the surface water stations SW-1 and SW-2 for the fall 1999

monitoring program. The surface water stations were found to be dry during the site visit and

therefore no surface water samples were collected.

May 2000 - 9 - 991-2818

5.0 INTERPRETATION OF GROUNDWATER QUALITY

The groundwater quality in the vicinity of the landfill site was assessed by collecting samples from

existing monitors and submitting them for chemical and physical analyses. The results of the field

and laboratory chemical and physical analyses conducted during the spring and fall 1999

monitoring program, along with the relevant Ontario Drinking Water Objectives (MOEE, 1994a),

are presented in Appendix B-1 .

This section discusses groundwater quality in the area of the site. Discussions related to

compliance with the Ontario Drinking Water Objectives relate specifically to non-health related

objectives (i.e. aesthetic parameters) and health-related parameters for which a Maximum

Acceptable Concentration or Interim Maximum Acceptable Concentration have been established.

5.1 Background Conditions

The background groundwater quality in the surficial sand layer is defined based on the data

available from monitors 94-6 and 97-16D. The groundwater quality in monitor 94-6 met the

Ontario Drinking Water Objectives (MOEE, 1994a) with the exception of manganese in the spring

1999 monitoring session. Monitoring well 97-16D groundwater quality met the Ontario Drinking

Water Objectives (ODWO) in 1999. The groundwater quality in monitor 97-16D is characterized

by higher concentrations of chloride, sodium, sulphate and TDS in comparison to the quality at

monitor 94-6 in 1999. The groundwater quality was generally consistent for each monitor between

the spring and fall 1999 monitoring sessions with slight increases in chloride, sodium and TDS

from spring to fall.

The background groundwater quality within the silty clay is characterized by the water quality data

available from groundwater monitors 97-16A, 97-16B and 97-16C. The groundwater quality in

these clay monitors is substantially different from that within the surficial sand layer and the levels

of chloride, DOC, sodium, iron, manganese and TDS typically exceed their respective ODWO.

Based on the 1999 data, the concentrations of the major cations; calcium, magnesium, sodium and

potassium increase with depth within the thick silty clay deposit. Sulphate concentrations are fairly

consistent with depth in the silty clay and are generally similar to sulphate and are generally similar

to sulphate levels in the surficial sand layer. Chloride concentrations increase significantly with

depth. The shallow surficial sand layer has chloride concentrations between 5 and 54 m a . The

deep monitoring well, 97-16A, exhibits chloride concentrations of up to 1560 mg/L. These patterns

May 2000 - 10- 991-2818

of solute concentrations with depth in thick Champlain Sea clay deposits have been described in the

literature with the porewater of the clay described as a mixture of glacial meltwater, rain, snow

and seawater (Desaulniers and Cherry, 1989).

As discussed in Section 5.2, typically the most useful landfill leachate indicator parameters are

ammonia, chloride, nitrate, sulphate, sodium, barium, boron, iron, manganese, strontium and TDS.

The range in concentrations of these parameters in the background groundwater is summarized in

the following table;

Nitrate Sulphate Sodium Barium Boron Iron

Notes: All concentrations reported in m@. ODWO - Ontario Drinking Water Objectives (MOEE, 1994a) A 0 - Aesthetic Objective MAC - Maximum Acceptable Concentration IMAC - Interim Maximum Acceptable Concentration 1 - background water quality represented by monitors 94-6 and 97-16D 2 - background water quality represented by 97- 16B and 97- 16C

5.2 Downgradient Conditions

The geological unit(s) contributing groundwater to the monitors; trend(s) in groundwater quality;

a comparison of groundwater quality to background conditions; and, comments on the

groundwater quality data are summarized in Table 2 for each of the "downgradient" monitors

sampled during the 1999 monitoring sessions. The discussion relating to the parameters elevated

compared to background conditions deals specifically with the indicator parameters presented in

Section 5.1.

May 2000 - 11 - 991-2818

Based on Table 2, the following interpretation summary is provided:

Groundwater quality in monitors 94-7B, 97-13A, 97 1-13B, 97-14A, 971 -14B, 97-15A and

97-15B are interpreted to not be impacted by landfill leachate.

Groundwater quality in monitor 94-9 is interpreted to not be impacted by landfill leachate

but the elevated nitrate levels are considered to be related to agricultural impacts on

groundwater quality; and

The groundwater quality in monitors 91-3,91-4,91-5, 94-7A, 94-8A and 94-10 is interpreted

to be impacted or potentially impacted by landfill leachate.

With respect to the indicator parameters presented in Section 5.1, all of these parameters are

considered landfill leachate indicator parameters at this site with the possible exception of nitrate

which appears to be more related to agricultural impacts on groundwater quality. Of these

landfill indicator parameters, chloride, sodium, boron and TDS are significantly elevated in the

background monitors within the silty clay deposit at this site and thus are less useful for

assessing impacts from the landfill on groundwater quality.

Based on the data available to date, sulphate appears to be the most useful landfill leachate

indicator parameters at this site for the following reasons:

The background levels in the surficial sand layer (12 - 44 mgL) are similar to background

levels in the silty clay (8 - 34 mgL) and;

Leachate originating from the landfill site appears to be characterized by elevated sulphate

concentrations in comparison to background levels.

This interpretation is consistent with that presented in Golder Associates (1997).

May 2000 - 12- 991-2818

The most recent sulphate concentrations in the groundwater monitors at the site are illustrated on

Figure 2. The leading eastward edge of the landfill leachate groundwater plume is interpreted to be

a limited distance beyond borehole 94-10. The available data for 94-9 suggest that the plume has

not impacted this monitor. The northward leading edge is interpreted to be a limited distance

beyond borehole 94-7. In summary, the groundwater plume is located within the boundary of the

buffer (to the north of the site) and the attenuation zone (to the northeast and east of the site).

Therefore, the site is in compliance with MOE Guideline B-7 (MOEE, 1994b).

May 2000 - 13- 991-2818

6.0 INTERPRETATION OF SURFACE WATER QUALITY

A surface water monitoring program was initiated for the St. Isidore landfill for the 1999

monitoring program. Surface water samples were taken at two stations, SW1 and SW2, shown

on Figure 2. SW1 is located at the northeast toe of the landfill, along the east ditch and property

line. The station is approximately 35m north of borehole 91-5. SW2 is located north of the

landfill, along the east ditch and property line and near the forested area. SW2 is approximately

5m south of an agricultural drain outlet. The stations SWl and SW2 were to be sampled during

the spring and fall monitoring sessions but the stations were dry in the fall.

Surface water monitoring station SW1 was stagnant with no measurable flow. The water was

clear with a yellowish-brown colour. Iron-staining was observed at the water's edge and iron-

bacteria was noticeable on the water surface. A swampy odour was perceived at SW1 at the time

of sampling. SW2 had stagnant water that was clear with a yellowish-brown colour. A musty,

organic odour was recorded.

The surface water quality at station SWl included the PWQO for the boron, total phosphorous

and silver. The water quality at station SW2 exceeded the PWQO for cadmium, cobalt, DO, iron

and total phosphorous.

In comparison to station SW2, station SW1 is characterized by elevated concentrations of the

following parameters which are indicative of impact from the landfill: alkalinity, boron, chloride

hardness, potassium, sodium, strontium, sulphate and TDS. The elevated nitrate levels at SWl

and SW2 may be result of agricultural impacts.

Additional seasonal surface water quality are required to conduct a meaningful surface water

compliance assessment.

May 2000 - 14- 99 1-28 18

7.0 SUMMARY AND CONCLUSIONS

Based on the results of the 1999 groundwater monitoring program, it is confirmed that chloride,

sodium, boron and TDS are significantly elevated in the background monitors within the silty

clay deposit at this site and thus are less useful for assessing impacts from the landfill on

groundwater quality. Based on the existing groundwater quality database, it is interpreted at this

time that sulphate appears to be the most useful landfill leachate indicator parameters at this site.

As such, the position of the leading edge of the landfill leachate groundwater plume has been

inferred based on the sulphate concentrations in groundwater.

It appears that the groundwater plume emanating from the landfill site is located within the

boundary of the buffer and attenuation zone and therefore the site is in compliance with MOE

Guideline B-7.

Additional seasonal surface water quality data are required to conduct a meaningful surface

water compliance assessment.
