Dear Trish:

Stone Environmental, Inc. (Stone) is pleased to present this report for the environmental sampling services that Stone performed in Windsor, VT on June 1,2006.

1.0 INTRODUCTION

%s work was performed to provide the Vermont Department of Environmental Conservation (VT DEC) with a better understanding of:

1. whether the storm or sewer lines are providing a preferential contaminant transport pathway from areas east and north of the Depot Avenue area where concentrations of tetrachloroethene (PCE) currently exceed 2 mg/L in a monitoring well (MW-202) and,

2. whether a series of drains located in the Station Restaurant contain PCE contamination.

Previous studies indicate that PCE was used at a dry cleaning establishment located due east of MW- ~ ~ w ~ v e ~ p ~ v ~ u s s a m p ~ g a n h d ~ d s o i l , - g r m $ f w a t e r - - - ' c k d g ~ d r + - cleaner and MW-202 has not definitively established the dry cleaning facility as the source of the observed environmental contamination. Several sites to the north of MW-202 have significant petroleum-based contamination however no PCE contamination has been found at these Sites.

During the June 2006 sampling that is the subject of this report, water, soil and sludge samples were collected at strategic locations in the vicinity of the storm and sewer systems that are present within the region of MW-202 and extend out to the north and east as shown on Figure 1. It is possible that these systems are providing preferential transport pathways for contamination to migrate in the direction of MW-202. The preferential pathways may consist of either or both transport within the sewer line or within the sewer line backfill material which is typically more conductive than the native soil.

The remainder of this report discusses the results of June 2006 sampling and analysis program and the relationship between the distribution of PCE and the storm and sewer systems.

2.0 INVESTIGATION METHODS

2.1 Sewer and Storm Line - Sludge and Water Sampllng

Access to the storm and sewer lines was achieved via manholes with the help of the Town of Windsor public works staff. Samples of sludge and water present within sanitary and storm sewer lines were collected from the sumps using an extension rod equipped with a sampling cup. All sludge samples were transferred immediately from the sampling cup to a methanol preserved vial. Samples were transferred under chain of custody to the VT DEC lab for EPA 8260 analyses. The following is a list of the sludge and water samples collected from the sanitary and storm sewer lines (see Figure 1 for sampling locations) and the rationale for collecting these samples:

1) Carter 1 - Collected sludge and water samples to assess whether PCE is present in the sanitary sewer system, east of the MW-202 area.

2) Carter 3 - Collected sludge and water samples to assess whether PCE is present in the sanitary sewer system, east of the MW-202 area.

3) Depot 1 - Collected sludge and water samples to assess whether PCE is present in the sanitary sewer system in the general area of MW-202. This location also represents the most eastern portion of the sewer system that currently receives flow from the Depot Avenue line. This location formerly received flow from the north via the Sewer 104 and Sewer 203 locations.

4) Sewer 104 - Collected sludge and water samples to assess whether PCE is present in the sanitary sewer system, north of Ascumey Metals and the MW-202 area. Note: A dye test conducted by the Town of Windsor Public Works staff determined that a floor drain within a gas station (Richard's Gulf) also drains to this location.

5) Sewer 203 - Collected sludge and water samples to assess whether PCE is present in the sanitary sewer system, south of the Ascutney Metals budding and north of the MW-202 area.

2.2 Sanitary and Storm Sewer Line - Sol! Sampllng

Soil samples were collected at three locations adjacent to the sanitary sewer lines located just south of MW-202 to determine if PCE contamination is present within the overburden soils. The soils encountered were primarily native although some fill material was noted in the boring logs which are included as Appendix A. Two samples were collected at different depths at each location using a dual casing direct push soil coring tool. The sample locations were strategically taken at confining layers observed in the boring and the base of the sewer man holes/piping. All samples were collected from the core liners and transferred directly into methanol preserved vials. Samples were transferred under chain of custody to the VT DEC lab for EPA method 8260 analyses. The following is a list of the samples collected and the associated sampling rationale:

1) SB-1- Located approximately 3-feet southwest of the Depot 1 sewer manhole. Two soil samples (4 and 6 feet below ground surface [BGS]) were collected to determine if PCE is present in the overburden soils at this location.

2) SB-2 - Located approximately 3-feet northeast of the Depot 1 sewer manhole. Two soil samples (4 and 5 feet below ground surface [BGS]) were collected to determine if PCE is present in the overburden soils at this location.

3) SB-3 - Located approximately 3-feet west of MW.202. Two soil samples (1 and 8 feet below ground surface [BGS]) were collected to determine if PCE is present in the overburden soils at this location. A 10-inch thick concrete slab was encountered at this location and required a concrete coring tool to penetrate the concrete. Below this slab, the sampling team encountered an oily layer that contained no odor.

2.3 Basement Plpe - Statlon Restaurant

One sludge sample was collected from a pipe located within the basement of the Station Restaurant located on Depot Avenue that may or may not drain out to the sewer system; the exact terminus for this pipe was not able to be discerned as part of this work. Several other pipes were observed in the basement of the Station Restaurant but we were only able to be sample one of them using the equipment available at the time. Thts pipe was also described by the owner as being the most odiferous of all the pipes. The sludge was transferred from the sampling device directly into methanol preserved vials and transferred under chain of custody to the VT DEC lab for EPA 8260 analyses.

3.0 QUALITY ASSURANCE/QUALITY CONTROL

A chain of custody was maintained on all samples from time of collection through delivery to the laboratory. Although a field duplicate was supposed to be collected for the soil samples, this duplicate sample was not collected.

4.0 RESULTS

The analytical results for the solid (sludge and soil) and water samples are presented on Tables 1 and 2, respectively.

5.0 CONCLUSIONS

Based on the results of the sampling and analysis program:

Contaminants other than PCE (acetone, bromomethane, 2-butanone, chlorobenzene, chloroform, chloromethane and toluene) are present at significant levels in sludge present in the sanitary sewer system north of MW-202 at the Sewer 104 location. Based on the reduction in concentration or absence of these same contaminants in the water samples collected at this location, it appears that these contaminants are strongly bound in the sludge and are not the causing any significant contamination of water in the sewer line. None of these same (non PCE) contaminants were present in MW-202 in August 2005, the

last time it was sampled, nor were they present in soil samples in the vicinity of MW-202. Since these contaminants are not present within the focus area (around MW-202) of this work, no further discussion of these contaminants are offered as part of this report. PCE contamination is not present at measurable levels in the sanitary sewer to the north of the Ascumey Metals facility. PCE contamination is present at measurable levels within the sanitary sewer north of the MW-202 area at the Sewer 203 location. PCE contamination is present at measurable levels within the sanitary sewer south of MW- 202 at the Depot 1 location. This location receives flow from the sewer line that extends out to the east of this area and formerly received flow from t h e n o r _ t h W h e S e w e d O h c L - ------- -

Sewer 104 locations. PCE contamination is not present at measurable levels within the storm sewer at the Depot SW location. PCE contamination is present at low levels in soil (SB-3) located directly beneath a concrete slab and adjacent to MW-202. This area also contained an oily layer however, since this investigation was targeting the PCE, no analyses regarding the makeup of this oily layer was performed as part of this work. Deeper contamination (between 4 and 8 feet BGS) was not observed at the three soil sampling locations (SB-1,2 and 3). PCE and a number of other contaminants (including carbon disulfide, chlorobenzene, chloroform, chloromethane and uichloroethene), are present at significant levels within the sludge sample collected within the basement of the Station Restaurant.

Based on the absencelpresence of PCE at these sampling locations, the following statements can be made regarding whether the stodsewer system or the Station Restaurant's drains are contributing to the PCE contamination at MW-202.

PCE is present in the sewer system to the north of the MW-202 and may have contributed to the PCE contamination located in the vicinity of MW-202. The presence of PCE in the Sewer 203 sample, coupled with the absence of PCE in the sewer 104 sample, suggests that the PCE contamination is emanating from someplace between these two samplhcatians; p o s ~ ~ e ~ k w ~ , a f s k e w f f o f i g m c ~ ----

into this sewer line between the Sewer 203 and Sewer 104 locations. There is however, a high level of uncertainty associated with this statement due to the fact that many variables can affect the levels of PCE in the sewer line. An example of such a variable would be the cleaning schedule for the removal of sludges from these sewer sumps which could greatly affect the correlation of PCE levels between these two sampling locations. PCE is present in the sewer system at the Depot 1 sampling location which currently receives flow from areas directly east of this location. The arrangement of the sewer lines associated with the Carter 1 and Carter 3 samples, does not allow for a definitive assessment regarding the source of the PCE in the Depot 1 water sample. The low level of PCE in the shallow soil directly below the concrete slab, and the absence of PCE at the deeper depths, indicate that the areas immediately adjacent to the sewer line are not likely to be providing preferential pathways for significant quantities of PCE to migrate along the sewer line in the region of MW-202.

PCE contamination in the basement of the Station Restaurant may be contributing to the contamination at MW-202; without knowing the terminus of the drain pipe(s) located in the basement, it is difficult to discern this relationship. Based on the relatively low levels of contamination in the samples collected as part of this work, it appears that the sewer system is not an ongoing source of PCE contamination.

6.0 RECOMMENDATIONS

To determine whether the contamination associated with the Station Restaurant's basement is a source of the contamination at MW-202, Stone recommends further investigation into the layout of the piping associated with the Station Restaurant's basement. Once the layout is known, samples should be collected at appropriate locations to better assess the relationship between these two areas of contamination. Conducting a dye test would also be useful to discern the layout of this drain system.

To gain a better understanding of the source area (presumed to be within the area of MW-202), a high density sampling and analyses program should be conducted in the region of MW-202. Reducing the uncertainty associated with the source area will allow for a more effective remedial solution.
