1. Introduction

1.1 General

This MCP Supplemental Phase II Report for the Allendale School Property (Supplemental Phase II Report)

summarizes the activities performed by the General Electric Company (GE) over the last several months concerning

the presence of polychlorinated biphenyls (PCBs) and other hazardous constituents at the Allendale School Property

in Pittsfield, Massachusetts (Site No. 1-0960). This Supplemental Phase II Report has been prepared consistent

with the MCP Supplemental Phase II Scope of Work for the Allendale School Property (Supplemental Phase II

SOW), dated November 1996, as conditionally approved by the Massachusetts Department of Environmental

Protection (MDEP) via letter dated March 5, 1997. This report is the second investigation report completed to date

for the Allendale School Property under the provisions of the Massachusetts Contingency Plan (MCP) (310 CMR

40.0000). A previous report, entitled MCP Interim Phase II Report for the Allendale School Property (Interim

Phase II Report, Blasland & Bouck, January 1993), was prepared consistent with the MCP and provided a

significant volume of information toward the characterization of current site conditions. To further supplement

the information presented in that report, additional field investigations were performed between April and July 1997

and are summarized herein. These two reports contain the majority of information necessary to satisfy MCP

requirements concerning the investigation component of an MCP Phase II Comprehensive Site Assessment,

although some remaining data needs have been identified and are presented herein. This report also represents a

proposal for filling those data'needs. Additional background information is presented below.

1.2 Background

The Allendale School Property is located to the north of the GE facility across the Tyler Street Extension, and is

bordered on the other three sides by residential areas (Figure l). The school occupies approximately 30,000 square

feet on approximately 12 acres. At the time of the school's construction in 1950, GE and the City of Pittsfield

BLASLAND, BOUCK & LEE, INC. SYR.fMJS£RSVMCGi\DMN9A39971550.WPD ~ 7/31/97 e n g i n e e r s S scientists 1-1

entered into an agreement under which GE allowed the City to remove soil material from GE property for use as

fill material at the school property.

Concerns associated with the Allendale School Property were initially identified by the MDEP during construction

of the Pittsfield Generating Company Facility (PGC Facility, formerly known as the Altresco Corporation

Cogeneration Facility), located on GE property southeast of the school property. The presence of PCBs in soil at

the GE property, and the available information concerning the prior use of fill material at the property, led to MDEP

concerns regarding the potential presence of PCBs in the fill at the Allendale School Property. In response, the

MDEP performed a soil and surface water sampling program for this area in January 1990, from which low levels

of PCBs were detected in the surficial soils in the southeast corner of the Allendale School Property. The MDEP

subsequently established a PCB concentration of 2 parts per million (ppm) (dry weight) as the "level of concern"

for surficial soils in this area. While two samples collected from the school property by the MDEP exceeded this

concentration, surface water sampling results did not detect PCBs.

The detection of PCBs above 2 ppm in soils by the MDEP at the property led to several subsequent sampling events

by GE to characterize the presence and extent of PCBs, as well as to assess the potential presence of other

hazardous constituents at the site. These activities were conducted between April and September 1990. As a result

* of these investigations, GE evaluated a range of options to reduce the potential for human contact with soils

containing PCBs above the MDEP's level of concern (i.e., 2 ppm). GE's evaluation was presented in a document

entitled Study of Potential Remedial Options for PCB-Containing Soils at the Allendale School Property (Blasland

& Bouck, September 1990). In a March 15, 1991 letter to GE, the MDEP conditionally approved the

containment/capping option presented in that report as an MCP Short-Term Measure (STM). As conditionally

approved by the MDEP, the STM involved the placement of a geotextile layer overlain with a minimum of 2 feet

of "clean" soil over those areas where soil PCB concentrations exceeded 2 ppm within the top 3 feet of existing

soil. In addition, improvements to the existing surface water drainage system in the area were part of the STM.

The MDEP's approval conditions were incorporated into a revised version of the report entitled Study of Potential

Remedial Options for PCB-Containing Soils at the Allendale School Property (Blasland & Bouck, April 1991).

Construction activities were initiated and completed in the summer of 1991, in accordance with the STM approved

by the MDEP.

In a letter dated March 6, 1992, the MDEP classified the Allendale School Property as a priority disposal site under

the MCP, required that further remedial response action be performed, and required that a Scope of Work (SOW)

for a Phase II Comprehensive Site Assessment be submitted within 60 days of the date of the letter. On May 4,

1992, GE submitted to the MDEP a Phase II SOW to address data needs associated with the Phase II

Comprehensive Site Assessment. The activities proposed in that document were conditionally approved by the

MDEP in a letter dated June 30, 1992 and subsequently initiated thereafter.

In January 1993, GE submitted to the MDEP the Interim Phase II Report. On September 13, 1996, after review

of that document, the MDEP directed GE to: (a) submit an Imminent Hazard Evaluation Proposal for surface and

near-surface soil sampling and analysis at the Allendale School Property to evaluate whether a potential "imminent

hazard" exists; (b) submit thereafter a Supplemental Phase II SOW proposing additional investigations; and (c)

upon completion of the additional investigations, submit a Supplemental Phase II Report for the property. On

September 27, 1996, GE submitted an Imminent Hazard Evaluation Proposal, which was conditionally approved

by the MDEP in a letter dated October 10,1996. In support of the imminent hazard evaluation, GE collected soil

samples from the surface (0- to 6-inches) and near-surface (6- to 12-inches) from 114 grid node locations based

on a 50-foot grid. Concentrations of PCBs were greater than 2 ppm in only two out of 114 locations, at both the

0- to 6-inch and 6- to 12-inch intervals (AS-96-76, AS-96-80). None of the 114 surface samples had PCB

concentrations greater than the MCP potential imminent hazard threshold of 10 ppm, and only one out of 114 of

the near-surface samples had a PCB concentration greater than 10 ppm (16 ppm, location AS-96-80, 6- to 12-inch

interval). On December 6, 1996, GE submitted the requested Imminent Hazard Evaluation Report. Based on the

BLASLAND, BOUCK & LEE, INC. SYR-F\usERaMCGi\DMN9A3997i550.wPO..7/3iw engineers & scientists 1-3

4

available information, GE concluded that a potential imminent hazard as defined in the MCP (310 CMR

40.032 l(2)(b)) does not exist at the schoolyard.

On November 18, 1996, GE submitted the Supplemental Phase II SOW, which was conditionally approved by the

MDEP in a letter dated March 5, 1997. In accordance with the Supplemental Phase II SOW, as well as the contents

of the MDEP's March 5, 1997 conditional approval letter, this report summarizes the activities performed between

April and July 1997. In general, the activities performed during this time frame included sampling and analysis

of soils, installation of monitoring wells, sampling and analysis of groundwater, and sampling and analysis of

stormwater/sediments. Additional information regarding the scope and results of these activities are presented in

subsequent sections of this report. The format of this report is discussed below.

1.3 Format of Document

The remainder of this Supplemental Phase II Report summarizes each of the activities completed to date by GE,

either as proposed in the Supplemental Phase II SOW, or as conditionally approved in subsequent correspondence

from the MDEP. The results of the supplemental investigations are discussed, as appropriate, in association with

data that were presented in prior reports. Additionally, a supplement will be prepared and submitted shortly that

contains the laboratory analytical summary data sheets from the 1996-7 investigations and a summary of the data

evaluation of those data sets (using the Tier I/Tier II data evaluation process outlined in the SAP/DCAQAP). The

format and contents of the remainder of this report are as follows:

• Section 2 of this document provides a summary of the supplemental soil investigations for the Allendale School

Property. The soil sampling effort was conducted to further define the horizontal and vertical extent of PCBs

and fill materials at the property and obtain additional information on the presence of other non-PCB hazardous

constituents at the property. As indicated in Section 2, the supplemental investigation activities were performed

2. Characterization of Property Soils

2.1 General

This section describes the supplemental investigation activities conducted at the Allendale School Property

concerning the presence and extent of PCBs and other hazardous constituents in the surface, near-surface, and

subsurface soils within the property. The locations of soil samples taken and results of PCB soil analytical data

from previous investigations are shown on Figures 2, 3, and 4. The locations of soil samples taken and the results

of PCB soil analytical data for this investigation are shown on Figure 5. All tasks that involved sampling and

analysis were performed in accordance with GE's Sampling and Analysis Plan/Data Collection and Analysis

Quality Assurance Plan (SAP/DCAQAP), dated May 1994, with subsequent revisions approved by the Agencies.

2.2 MCP Investigations of Surface and Near-Surface Soils

Since the Interim Phase II Report was submitted to the MDEP in January 1993, surficial soils at the Allendale

School Property have been investigated in October 1996 as part of an imminent hazard evaluation, and more

recently as part of the Allendale School expansion activities. Specifically, the results of surface soil sampling

completed in October 1996 indicated the presence of PCBs at concentrations greater than 2 ppm at two sample

locations (AS-96-76 and AS-96-80, for both the 0- to 6- inch and 6- to 12-inch depth increments) along the east

side of the property (Figure 4). To further define the extent of PCBs in surface soils near these locations, additional

surface and near-surface soil samples were obtained as part of the Supplemental Phase II investigations.

In April 1997, surface soil samples were obtained from 0- to 6-inch and 6- to 12-inch depth intervals near the two

previous sample locations discussed above where PCBs were detected (in areas outside of the cap) at concentrations

exceeding 2 ppm. Samples AS-97-120, AS-97-121, and AS-97-122 were located approximately 20 feet north,

south, and east, respectively, of sample location AS-96-76. Samples AS-97-123, AS-97-124, AS-97-125, and AS-

BLASLAND, BOUCK & LEE, INC. SYR-F\uSERaMCGi\DMN9A3997i550.wPO.. 7/31/97 engineers & scientists 2-1

97-126 were located within 20 feet west, north, south, and east, respectively, of sample location AS-96-80. These

sample locations are shown on Figure 5.

Each of the surface and near-surface soil samples (14 total) was analyzed for PCBs, and screened for volatile

organic compounds (VOCs ) using a portable photoionization detector (PID). All samples with a screening result

greater than 10 PID units were to be submitted for analysis of constituents listed in Appendix IX of 40 CFR Part

264, plus three additional constituents - benzidine, 2-chloroethyl vinyl ether, and 1,2-diphenylhydrazine, plus

pesticides and herbicides (hereafter referred to as Appendix IX+3). Since screening results greater than 10 PID

units were not recorded, no samples were submitted for Appendix IX+3 analysis.

Results of all soil PCB analyses are summarized in Table 1. PCBs were not detected in either the 0- to 6-inch or

6- to 12-inch depth interval at location AS-97-121. With respect to the remaining locations, all six samples taken

from the 0- to 6-inch depth interval had PCB concentrations less than 2 ppm, ranging from 0.084 ppm to 1.9 ppm,

while five samples taken from the 6- to 12-inch depth interval had PCB concentrations greater than 2 ppm, ranging

from 4.2 ppm to 12 ppm.

2.3 MCP Supplemental Investigation of Subsurface Soils

The MDEP's letter of September 13, 1996 required GE to propose additional soil borings and sampling to define

the horizontal extent of PCBs outside the capped area and further define the vertical extent of PCBs at the southern

edge of the school property. A total of 26 soil borings were installed based on the proposal in the Supplemental

Phase II SOW (16 boring locations), supplemented by the March 5, 1997 conditional approval letter from the

MDEP (adding 10 additional boring locations). AH boring locations are shown on Figure 5.

BLASLAND, BOUCK & LEE, INC. SYR-F:\USERS\MCGI\DMN9A3997I550WPD-7/31/97 engineers i scientists 2-2

Five borings (ASB-1, ASB-2, ASB-4, ASB-5, and SCH-1) were installed based on a 200-foot by 200-foot grid in

the area outside the surface cover, as shown on Figure 5. Fifteen additional soil borings were installed at the

following locations outside of the surface cover limits:

• one boring (SCH-2) at the same location as the former temporary piezometer A-1;

• one boring (SCH-3) at the same location as the former temporary piezometer A-2;

• one boring (ASB-3) at the location of the Gifford Engineering sample location B-22-96 (to verify the prior

sampling results at that location);

• two borings (ASB-14 and ASB-15) located 40 feet to the northeast and northwest, respectively, from ASB-3;

• three borings (ASB-6, ASB-7, and ASB-8) between ASB-3 and former sampling locations T-9 through T-12

(see Figure 3);

• two borings (ASB-9 and ASB-10) between the back of the school building and the capped area;

• one boring (ASB-11) to the east of the cap as close as feasible to the existing wetland area;

• two borings (ASB-12 and SCH-4) to the south of the cap and north of the Tyler Street Extension; and

• two borings (ASB-20 and ASB-21) at prior surface soil sample locations AS-96-76, and AS-96-80,

respectively.

In addition, six soil borings (ASB-13, ASB-16, ASB-17, ASB-18, ASB-19, and ASB-22) were installed within the

capped area. Those six additional soil borings included:

• one boring (ASB-13) installed between boring B-60 and sample location SS-24;

• one boring (ASB-16) installed between boring B-18 and sample location SS-24;

• one boring (ASB-17) installed between borings B-2 and B-8;

• one boring (ASB-18) installed between borings B-9 and B-17;

• one boring (ASB-19) installed between sample location SS-24 and the eastern edge of the cap; and

• one boring (ASB-22) installed at boring location K.-6.

BLASLAND, BOUCK & LEE, INC. SYR-F\uSERaMCGi\DMN9A3997i550.wPo-7/3ifl7 engineers & scientists 2-3

The sampling performed at each location differed slightly depending on the specific boring, but generally included

samples from the surface and near-surface soils, and subsequent subsurface sampling in 2-foot depth increments.

Samples were collected to a depth of approximately 2 feet below the fill/original grade interface, as visually

determined during the field activities. A total of 148 samples from 26 soil borings were submitted for analysis of

PCBs (Table 1). All soil samples were analyzed for PCBs, and screened for VOCs using a PID. Since screening

results greater than 10 PID units were not detected, no samples were submitted for Appendix IX+3 analysis. Upon

completion, the boreholes were abandoned by placing a cement/bentonite grout seal via tremie pipe from the total

boring depth to within 1 foot of the ground surface. Topsoil was then placed in the borehole up to the ground

surface level. This method of cap repair was based upon verbal agreements between GE and the MDEP.

In addition, the following seven soil samples from selected borings were submitted for analysis of Appendix IX+3

constituents (Tables 2-4):

• the easternmost new boring between the capped area and the Tyler Street Extension (SCH-4, 8- to 10-foot

depth interval);

• the boring to the east of the cap near the wetland area (ASB-11, 3- to 5-foot depth interval);

• the boring between the capped area and Virginia Avenue (SCH-2, 6- to 8-foot depth interval);

• one of the borings between the school building and the cap (SCH-3, 2- to 4-foot depth interval);

• the boring at Gifford Engineering sample location B-22-96 (ASB-3, 3- to 5-foot depth interval);

• the upgradient boring to the north of the school (SCH-1, 8- to 10-foot depth interval); and

• boring ASB-19 (2- to 4-foot depth interval).

All of these borings are shown on Figure 5. A summary of the analytical results generated from these efforts is

presented below.

BLASLAND, BOUCK & LEE, INC. SYR-F:\USEfWCG IXDMN9A39971550.WPD - 7/31 /97 engineers & scientists 2-4

2.3.1 PCBs

A total of 70 of 148 subsurface soil samples indicated the presence of PCBs (Table 1). Fifty-one of the 70 samples

had PCB concentrations less than 2 ppm, and 15 samples exhibited PCB concentrations ranging from 2 ppm to 50

ppm. Four samples (ASB-12, 3- to 5-feet; ASB-18, 4- to 6-feet; ASB-19, 2- to 4-feet; and ASB-19, 4- to 6-feet)

exhibited PCB concentrations greater than 50 ppm. The maximum PCB concentration measured (810 ppm)

occurred within the limits of capped area at soil boring ASB-19 (4- to 6-foot depth interval).

2.3.2 Other Non-PCB Hazardous Constituents

Regarding Appendix IX+3 VOCs, only chlorobenzene was detected in one soil boring (ASB-19) at a concentration

of 0.009 ppm (Table 2). No other VOCs were detected.

The following 13 semivolatile organic compounds (SVOCs) were detected at concentrations exceeding their

Contract Laboratory Program (CLP)-required quantitation limits: 1,2,4,5-tetrachlorobenzene, anthracene,

benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, benzo(g,h,i)perylene, benzo(k)fluoranthene, bis(2-

ethylhexyl)phthalate, chrysene, fluoranthene, indeno(l,2,3-cd)pyrene, phenanthrene, and pyrene (Table 2). Ten

SVOCs were detected in at least one sample at estimated concentrations greater than the associated instrument

detection limits, but less than the CLP-required quantitation limits. Among these compounds, one compound,

bis(2-ethylhexyl)phthalate, was also detected at similar concentrations in the associated method blank. These

SVOC compounds were detected primarily in samples from soil borings ASB-3 and SCH-3.

Two pesticides were detected at concentrations greater than the CLP-required quantitation limits (Table 2). 4,4'-

DDT was detected in SCH-3 at a concentration of 0.0023 ppm, while dieldrin was detected in ASB-3 and ASB-19

at concentrations of 0.23 ppm and 6.4 ppm, respectively.

BLASLAND, BOUCK & LEE, INC. SYR-F\usERSyMCGi\DMN9A3997i550.wPD.-7/3iw engineers S scientists 2-5

Several inorganic constituents were detected in the soil samples submitted for Appendix IX+3 constituents (Table

3). For the purposes of this report, discussion will be limited to the RCRA metals. Eight RCRA metals were

detected in the soil samples. Three metals (cadmium, selenium, and silver) were detected in at least one sample

at estimated concentrations greater than the instrument detection limits for the compounds, but less than the CLP-

required detection limits. Mercury was detected in three samples, at concentrations ranging from 0.04 ppm to 0.13

ppm. Four metals (arsenic, barium, chromium, and lead) were detected in all seven soil samples.

Polychlorinated dibenzo-p-dioxins (PCDDs) were detected in two samples, ASB-3 (3- to 5-feet) and ASB-19 (2-

to 4-feet), at 0.00019 ppm and 0.001 ppm total PCDDs, respectively (Table 4). PCDFs were detected in five

samples, ASB-3 (3- to 5-feet), ASB-11 (3- to 5-feet), ASB-19 (2- to 4-feet), SCH-1 (8- to 10-feet), and SCH-3 (2-

to 4-feet), at total PCDF concentrations ranging from 0.00000084 ppm to 0.0061 ppm.

2.4 Capped Area Soil Sampling and Analysis

In its conditional approval letter dated March 5, 1997, the MDEP required sampling of the existing cap materials

in the vicinity of each of the six borings installed within the capped area and through the cap (Figure 5). These

additional samples were collected following the installation and sampling of the six borings within the capped area.

One sample was placed within 5 feet of each boring (ASB-13, ASB-16, ASB-17, ASB-18, ASB-19, and ASB-22).

Samples were collected from the 0- to 6-inch depth interval and thereafter in 1-foot intervals until the base of the

cap was reached. All soil samples were analyzed for PCBs, and screened for VOCs using a PID. AH samples with

screening results greater than 10 PID units were to be analyzed for Appendix IX+3 constituents; however no results

greater than 10 PID units were recorded.

A total of 18 samples of the cap materials were collected. PCBs were detected in five samples, but at

concentrations ranging only as high as 0.70 ppm (occurring at AS-97-127 in the 1.5- to 2-foot depth interval). The

maximum detected PCB concentration was consistent with the results of sampling and analysis of the surface cover

BLASLAND, BOUCK & LEE, INC. SYR-FAUSERRMCGI\DMN9A3997I550.\WO-7/31/97 engineers & scientists 2-6

materials prior to their use in the construction of the surface cover. Specifically, the materials proposed for use in

the construction of the surface cover were sampled and analyzed for PCBs and select Appendix IX+3 constituents.

The maximum detected PCB concentration resulting from this effort (0.8 ppm) was greater than the results recently

obtained as described above. In addition, all of the results are below the PCB concentration considered acceptable

for "clean" soils.

2.5 Miscellaneous Investigations

In April 1996, Gifford Engineering, on behalf of Barry Architects, Inc. and at the direction of the City of Pittsfield,

installed seven borings within the property. Soil samples were collected primarily for structural purposes in support

of proposed building additions to the school building and were not specifically collected as part of the Phase II

investigation. However, soil samples from the top 4 feet at two borings were submitted for PCB analysis. The

results indicated that PCBs were not present at concentrations above 2 ppm. At the MDEP's direction, Gifford

Engineering completed additional soil sampling on August 22, 1996 (Figure 3). That additional soil sampling

consisted of the installation of 13 borings, and collection of soil samples collected in 2-foot intervals from ground

surface to depths of up to 10 feet (Gifford Engineering, 1996). (Note: some of the identification names of the soil

borings collected by Gifford Engineering were identical to soil borings taken by GE. To better distinguish between

the borings, the Gifford Engineering soil boring labels were modified with a "-96" attached to each soil boring

label. Hence, the Gifford Engineering soil borings are now labeled B-20-96 through B-32-96). All analytical

results from this sampling indicated PCB concentrations of less than 2 ppm with the exception of four subsurface

borings. These borings consisted of B-20-96 (8- to 10-feet), B-21-96 (4- to 6-feet), B-22-96 (2- to 4-feet), and B-

22-96 (4- to 6-feet), which had PCB concentrations of 5.42, 10.6, 24.4 and 2.73 ppm, respectively.

In April 1997, 26 additional soil borings were collected in the vicinity of the proposed building expansion prior to

the start of excavations (Figure 2). The borings were sampled at 2-foot intervals to depths at least 2-feet beyond

the extent of fill as determined based on historical topographic mapping predating the construction of the school.

BLASLAND, BOUCK & LEE, INC. SYR-F:\USEIWCGI\DMN9A3997I5»WPD-. 7/31/97 engineers & scientists 2-7

Of the 91 soil samples submitted for analysis, 63 showed non-detectable levels of PCBs. Sample PRE-24 (4- to

6-foot depth interval) had a measured PCB concentration of 11 ppm. The remaining samples for which PCBs were

detected had concentrations of 1 ppm or less.

In April 1997, the City of Pittsfield removed two underground storage tanks from the Allendale School Property

located along the western side of the main school building (Figure 2). On April 23, 1997, GE collected two soil

samples from locations beneath each of the former tanks (AS-UST-1 and AS-UST-2) at the base of the excavation.

These samples were collected as grab samples from the 0- to 6-inch depth interval beneath the former tanks, and

submitted for PCB analysis. The soil samples had PCB concentrations of 0.86 ppm and 0.059 ppm.

2.6 Geologic Characteristics

Site-specific geologic information was collected during implementation of previous and recent subsurface

investigations at the site. This information was primarily obtained from soil borings advanced during various

subsurface investigations, as outlined in Sections 2.2 and 2.3 of this report, and depicted on Figures 2-5. All

available subsurface geologic logs were evaluated and re-interpreted, as appropriate, to develop a generalized

stratigraphy of the Allendale School Property that is consistent with the geologic framework of the region and

adjacent areas of investigation.

Figures 3 and 5 show the locations of the three cross sections developed to show the generalized stratigraphy of

the Allendale School Property. Figure 6 (Cross Section A-A'), Figure 7 (Cross Section B-B'), and Figure 8 (Cross

Section C-C) were originally developed for the MCP Interim Phase II Report, and have been revised and updated

with geologic information obtained during the recent supplemental investigation. Subsurface boring logs from the

recent Supplemental Phase II investigations, as well as previous investigations, are presented in Attachment B.

In general, the subsurface soils encountered at the site consist of the following units from ground surface

downward: 2 to 3 feet of cap material ("clean" soil and a geotextile layer); fill/surficial soils - including topsoil and

recent alluvial sediments; glaciofluvial sands; black organic peat and silt, gray silt, gray to black sand and silt, and

clayey silt interpreted as glacial till. These overburden units unconformably overlie meta-sedimentary bedrock.

A general discussion of the site geology as encountered at the Allendale School Property is presented below.

2.6.1 Fill

Fill materials, where detected, consisted primarily of brown, fine to medium sand with some areas of silt and clay.

The fill material appears to have been used to elevate the ground surface in a preexisting depression, which was

located in the present area of the schoolyard. The fill thickness is generally 4 feet thick, but does extend to a

maximum observed depth of 11 feet below grade, and appears to decrease outside of the capped area, as depicted

in the cross sections (Figures 6 through 8).

2.6.2 Glaciofluvial Sand

This unit is described as light brown to red-brown, fine to coarse, loose, poorly- to well-sorted sand with

approximately 10 to 20 percent of fine to medium gravel and up to 20 percent silt. In general, this unit was

observed in the northern and western portions of the site, and was absent in the capped area of the site as shown

in the cross sections (Figures 6 through 8).

2.6.3 Till

The gray-brown silt, black sand and silt, and clayey silt, interpreted as a glacial till unit, was generally encountered

throughout the site except where the upper surface of the unit was below the completion depth of the borings as

shown in the cross sections (Figures 6 through 8). The top of the till unit was encountered at 6 feet below grade

in the northern portion of the site and at approximately 11 feet below grade in the central portion of the site where

cap was constructed.

BLASLAND, BOUCK & LEE, INC. SYR-F\usEF®,MCGi\DMN97\3997i550.wpo-7/3ifl7 engineers 4 scientists 2-9

2.6.4 Peat

The black organic peat and silt unit was encountered underlying the fill material along the south and southeastern

site boundary as depicted on Figure 6 (Cross Section A-A')- Figure 8 (Cross Section C-C) indicates that the peat

unit extends north approximately 350 feet into the Allendale School Property, and is underlain by the till unit. The

peat unit may be indicative of the marshy conditions that were previously present throughout the site (prior to the

filling activities and development of the property), and still present today in certain portions of the property.

2.6.5 Cross Sections

Figure 6 (Cross Section A-A') depicts the general stratigraphy encountered along the south and southeastern

boundary of the study area. A fill layer approximately 5 feet thick occurs along the southern boundary of the site

thinning to the east, and not observed to the west. The fill material is underlain by the black peat and silt unit. The

till unit was observed at the base of all except the western borings. Red-brown glaciofluvial sand was observed

near the surface in the western portion of the site where the fill and till units were not observed.

Figure 7 (Cross Section B-B') depicts the general stratigraphy encountered along the north, northwestern boundary

of the study area. Fill material ranging from 4 to 11 feet in thickness occurs in the central portion of the site. Fill

material was not observed in the borings at the eastern and western ends of the B-B' cross section line. The fill

material is underlain by the black and gray-brown till unit. The red-brown glaciofluvial sand unit was observed

in the eastern and western portions of the site where the fill was not observed.

The general stratigraphy encountered along the north-south trending cross section C-C is presented on Figure 8.

The cross section depicts a thin layer of fill materials approximately 2 to 3 feet thick across the majority of the site.

An approximately 5-foot thick wedge of the glaciofluvial sand unit was observed in the northern portion of the site,

where there was no evidence of the fill layer. A 1- to 2-foot thick layer of the black peat and silt unit was observed

along the southern portion of the C-C cross section line. The entire section is underlain by the till unit.

2.7 Extent of Affected Soil

Figure 9 illustrates the general horizontal extent of impacted material as areas containing PCB concentrations

greater than 2 ppm, and Figures 6, 7, and 8 illustrate the general vertical extent of impact with respect to subsurface

lithology. As illustrated by these figures, the horizontal extent of PCB-containing soil material is generally

encompassed by the existing cap, with the exception of relatively small areas along its eastern side (in vicinity of

locations AS-96-76 and AS-96-80), the southwestern side of the main school building (in the vicinity of ASB-3),

as well as along Tyler Street Extension (in the vicinity of ASB-12).

The vertical extent of PCB presence appears to generally range 5 to 7 feet below the surface, but up to

approximately 12 feet near the south corner of the main school building (borings B-20-96 and B-66). In some

instances, the vertical extent of PCBs in the subsurface soils has not been fully delineated. As a result, some

additional investigations are proposed, as discussed in Section 6.

With respect to the presence of subsurface fill material, as part of the preparation of the Supplemental Phase II

SOW, a review of available information was conducted to estimate the extent of fill material and PCBs. Historical

drawings were obtained which show topographical information associated with the filling efforts that occurred on

the property. The current site topography (before the recent construction of the cap) closely matched the elevations

associated with the drawing from 1951 (representing post-filling conditions). Based on this information, it was

concluded that no significant additional fill was brought onto the Allendale School Property after the 1951

construction efforts.

3. Groundwater Sampling and Analysis

3.1 General

Groundwater investigations were originally conducted at the Allendale School Property in August and December

1992. The analytical results of filtered samples from the December sampling effort showed the presence of PCBs

at concentrations of up to 0.19 parts per billion (ppb). Based on the results of these initial efforts, the scope of the

groundwater component of the MCP Phase II investigation has expanded. This section describes the sampling

efforts and presents the results of the sample analyses. All tasks that involved sampling and analysis were

performed in accordance with GE's SAP/DCAQAP.

3.2 Description of Groundwater Sampling and Analysis

To further assess die potential presence of PCBs and other Appendix IX+3 constituents in groundwater, four of the

soil borings described in Section 2.3 were converted to monitoring wells. These included: (1) the boring located

between the capped area and Virginia Avenue (SCH-2); (2) the upgradient boring to the north of the school (SCH-

1); (3) one of the borings between the school building and the capped area (SCH-3); and (4) the easternmost new

boring between die capped area and the Tyler Street Extension (SCH-4), as illustrated on Figure 5. The areas south

of the school property are already encompassed by a monitoring well network, including existing monitoring wells

78-6 and NY-4, along with die other monitoring wells present at the Hill 78 Area Site. New monitoring well SCH-1

was installed to provide data from north of the area, monitoring wells SCH-2 and SCH-3 were installed to provide

data from the areas of the former temporary piezometers, and monitoring well SCH-4 was installed to provide

additional groundwater data in the southeastern area of the site.

Groundwater from the four new monitoring wells (SCH-1, SCH-2, SCH-3, and SCH-4) and existing downgradient

wells 78-6 and NY-4 were sampled on May 19 and 20, 1997 and analyzed for PCBs and Appendix IX+3

constituents. Water level measurements were obtained on May 19, 1997 and the well volumes calculated. The

BIASLAND. BOUCK & LEE. INC. SYR-F\uSERS\MCGi\OMN9A3997i550.wPO--7/3ifl7 engineers & scientists 3-1

wells were purged of their well volumes and allowed to recharge overnight. Prior to sampling on May 20, 1997.

each well was again purged until five well volumes were evacuated, and samples were then collected. The samples

were analyzed for PCBs (filtered by lab/unfiltered), inorganics (filtered in field/unfiltered), and additional Appendix

IX+3 constituents. The results of the recent groundwater sampling are discussed below, and shown in Tables 5,

6, and 7.

3.3 Groundwater Sampling and Analysis Results

3.3.1 PCBs

PCBs were detected in one groundwater sample, the unfiltered water sample taken from well 78-6, at a

concentration of 0.0059 ppm total PCB (Table 5). All other samples collected in May 1997 (filtered and unfiltered)

had non-detectable levels of PCBs. PCBs had previously been detected in well NY-4 (0.017 ppm unfiltered, 0.0013

ppm filtered) in September 1996; however, PCB concentrations in well NY-4 were not detected in May 1997.

3.3.2 Other Non-PCB Hazardous Constituents

No VOCs were detected in the groundwater samples taken during the May 20, 1997 sampling effort. VOCs had

been detected in previous samples obtained from NY-4 and 78-6 in January/February 1991 (Table 6). Methylene

chloride was detected in 78-6 (estimated concentration less than the CLP-required quantitation limit) and NY-4

(0.013 ppm), but was also detected in the laboratory blank. Acetone, 1,1,1-trichloroethane, tetrachloroethene, and

toluene were all detected in NY-4 at estimated concentrations less than their respective CLP-required quantitation

limit. Trichloroethene was detected at a concentration of 0.005 ppm in NY-4 during the January/February 1991

sampling effort.

No SVOCs were detected in any of these wells during any sampling event at concentrations greater than the CLP-

required quantitation limit. During the May 1997 sampling, bis(2-ethylhexyl)phthalate and di-n-butylphthalate

were found at non-detectable levels or at estimated concentrations greater than the instrument quantitation limit,

BLASLAND, BOUCK & LEE. INC. srR-FAUS£RaMCGi\DMN97U997i550.wTO--7/ji^7 engineers & scientists 3-2

but less than the CLP-required detection limit (Table 6). Bis(2-ethylhexyl)phthalate, di-n-butylphthalate, and

phenanthrene were found at estimated concentrations less than their respective CLP-required quantitation limit in

NY-4 during the May 1988 sampling effort. No other SVOCs were detected in the groundwater samples.

No pesticides or herbicides were detected in the groundwater samples. PCDDs were also not detected in any of

the groundwater samples. While PCDFs were not detected in wells NY-4, SCH-1, SCH-2, SCH-3, or SCH-4, well

78-6 had a total PCDF concentration of 0.000000349 ppm.

RCRA metals were primarily detected in the unfiltered samples submitted for analysis from the May 20, 1997

sampling effort (Table 7). All of the filtered samples had either non-detectable levels or estimated concentrations

less than the respective CLP-required detection limit. Metals were detected at higher concentrations in the

unfiltered samples. Arsenic was detected in all six of the unfiltered samples, ranging in concentration from 0.0136

ppm to 0.073 ppm. Barium was detected in SCH-1, SCH-3, and SCH-4 at concentrations of 0.943 ppm, 0.356 ppm,

and 0.387 ppm, respectively. Cadmium was detected in SCH-1 and SCH-3 at estimated concentrations less than

the CLP-required detection limit, but greater than their respective instrument detection limits. Chromium was

detected in five of six of the unfiltered samples, ranging in concentration from 0.046 ppm to 0.262 ppm. Lead was

detected in all six of the unfiltered samples, ranging in concentration from 0.0034 ppm to 0.110 ppm. Selenium

was not detected in any of the unfiltered samples; however, it was detected in the filtered samples SCH-1 and NY-4

at estimated concentrations less than the CLP-required detection limit, but greater than the instrument detection

limit.

3.4 Hydrogeologic Characteristics

Water table elevations were measured on May 20, 1997 during the groundwater sampling effort. However, the

water table elevation contour map generated from the resulting data provided a groundwater elevation and flow

configuration different from the map that was anticipated. In response, GE performed another set of water table

BLASLAND, BOUCK & LEE, INC. SYR-F:\USER&MCG l\DMN9A39971550.WPD - 7/31^7 engineers & scientists 3-3

elevation measurements on July 9, 1997 to verify the data collected in May 1997 and/or to modify the

characterization of the water table. The results of this second monitoring event were generally consistent with the

first event and were used to develop a water table elevation contour map (Figure 10). Table 8 summarizes the

groundwater elevation data from both events. The contour map indicates that groundwater flow is to the east-

northeast toward the marshy area located near the southeastern corner of the site. The marsh is located in a

topographically low area, which appears to be a discharge zone for the site. The groundwater table contours

developed in this report may be influenced by the data associated with well SCH-2. As a result, additional

groundwater elevation data is proposed to be collected in spatially representative locations throughout the property.

Specific details are presented in Section 6.

The horizontal hydraulic gradients for the site were calculated from groundwater elevation measurements collected

on July 9, 1997; the water table elevation contour map is presented as Figure 10. The horizontal hydraulic gradient

for the hill area located in the southwest corner of the site was interpreted to be 0.023 feet/foot. The horizontal

hydraulic gradient for the capped area of the site (between monitoring wells SCH-2 and SCH-3) was calculated to

be 0.0084 feet/foot.

Based on information developed during the investigations completed in the Hill 78 area, immediately to the south

of the Allendale School Area, the till unit, which was encountered throughout the investigation area, is a low

permeability unit relative to the overlying fill material and glaciofluvial sands. The till, therefore, appears to act

as a confining unit by restricting the vertical movement of groundwater. Hydraulic conductivity testing performed

at monitoring wells screened in these geologic units at the Hill 78 investigation area indicated geometric mean

hydraulic conductivities for the fill and till units of 1.07x10° centimeters/second (cm/sec), and 1.16x10'5 cm/sec,

respectively.

4. Miscellaneous Investigations/Evaluations

4.1 Information on Background Concentrations

The approach proposed by GE to develop background conditions for the Allendale School Property was presented

in the Supplemental Phase II SOW and involved the use of: (1) soil and groundwater data from the upgradient

boring and well to be installed to the north of the school (SCH-1); and (2) background soil and groundwater data

obtained in accordance with GE's Background Sampling Plan for the GE Facility Sites (Blasland, Bouck & Lee,

April 1996) (Background Sampling Plan). This approach was based on the assumption that the Background

Sampling Plan, which was submitted to the MDEP on April 23, 1996, would be approved in sufficient time to

obtain the background data and include those data in this report. However, since the Background Sampling Plan

has not yet been approved by the MDEP, the associated data have not yet been collected. Accordingly, only the

data for soil boring/monitoring well SCH-1 are available for evaluation of background conditions. Such an

evaluation is not presented in this report at this time (based on the above discussion). However, a discussion of the

available data from well SCH-1 is provided below.

While soil from SCH-1 contained PCBs at a concentration of 0.16 ppm in the sample collected from the 0- to 6-

inch depth interval, PCBs were not detected in the deeper samples. One soil sample, collected from the 8- to 10-

foot depth interval, was analyzed for Appendix IX+3 compounds. Bis(2-ethylhexyl)phthalate was detected in this

sample, but at an estimated concentration greater than the instrument detection limit, and less than the CLP-required

quantitation limit. Bis(2-ethylhexyl) phthalate was also detected at similar concentrations in the associated method

blank. The only other non-PCB compounds detected in SCH-1 were TCDFs, at a concentration of 0.00000084 ppm

(total TCDF). A total of six RCRA metals were detected in the sample collected from the 8- to 10-foot depth

interval at SCH-1. Of these metals, two (cadmium and silver) were detected at estimated concentrations greater

than their respective instrument detection limits, but less than the CLP-required detection limits. The remaining

BLASLAND, BOUCK & LEE, INC. SYR-F:\USEFISVMCGI\DMN9A3997IS50.WPD •- 701/37 engineers & scientists 4-1

metals were detected at the following concentrations in SCH-1: arsenic (6.3 ppm), barium (51.7 ppm), chromium

(13.3 ppm), and lead (9.3 ppm).

Groundwater from SCH-1 did not contain PCBs or VOCs. Di-n-butylphthalate was detected in SCH-1 at 0.005

ppm, which is an estimated concentration greater than the instrument detection limit, but less than the CLP-required

quantitation limit. No RCRA metals were detected at levels above the CLP-required detection limits in the filtered

sample. Four RCRA metals were detected in the unfiltered sample at levels greater than the CLP-required detection

limits: arsenic (0.073 ppm), barium (0.943 ppm), chromium (0.262 ppm), and lead (0.110 ppm).

4.2 Stormwater and Sediment Sampling and Analysis

The MDEP's September 13,1996 letter directed GE to propose surface water (i.e., runoff through the stormwater

drainage system) and sediment sampling for PCBs from the storm drainage system at locations "upstream" and

"downstream" of the school property. At the time the Supplemental Phase II SOW was submitted, "upstream"

surface water and sediment samples had been collected from the stormwater line at the intersection of Brighton

Avenue and Dalton Avenue, pursuant to the MCP Supplemental Phase II SOW/RFI Proposal for the Hill 78 Area

Site. Therefore, it was proposed that the results from these samples be used to characterize upstream PCB

concentrations for the Allendale School Property (as well as the Hill 78 Area). In addition, downstream PCB levels

would be characterized with samples of surface water and sediments to be collected for PCB analysis from the

manhole located on the 42-inch diameter stormwater drainage line, which is situated near the southwestern corner

of the site on the centerline of Tyler Street Extension, as shown on Figure 5. This manhole is at a location to which

stormwater from the Allendale School Property drains, and thus is an appropriate "downstream" location for

assessing whether any migration of PCBs from the school property is occurring through the drainage system.

The MDEP responded in its March 5, 1997 letter by requiring GE to collect sediment and surface water samples

from both upstream and downstream locations within 12 hours of each other, and during similar weather conditions.

BLASLAND, BOUCK & LEE. INC. SYR-F:\usERaMCGi\DMN97^997i5».wTO-7/31/97 engineers & scientists 4-2

A storm event of suitable magnitude that would be conducive for such sampling occurred on July 7, 1997.

Sediment and surface water samples were obtained from the "upstream" location (BA-MH-SED1 and BA-MH-

SW1, respectively), and a surface water sample was taken from the "downstream" location (TS-EXT-MH-SW1).

Since no sediment was present at the "downstream" site, no sediment sample could be obtained from a

"downstream" location. No PCBs were detected in any of the samples collected (detection limit of 0.001 mg/L for

stormwater, and 0.039 mg/kg for sediments).

4.3 Status of Stormwater Drain Lines

To clarify the status of a 15-inch stormwater drain line located along the southern edge of the property, as requested

by the MDEP, the as-built drawing associated with the Allendale School Property capping project was reviewed

in the Supplemental Phase II SOW to determine whether or not the previous 15-inch stormwater line was replaced

during the drainage improvement efforts conducted as part of the STM. Based on that review, the previously

existing 15-inch stormwater line, which was located along the southern boundary of the property (in an east to west

orientation), was replaced with a 24-inch perforated polyvinyl chloride (PVC) pipeline and a 30-inch PVC pipeline.

A site plan that indicates die location of storm water drains at and around the site as documented by the as-built

drawing for the capping project is shown as Attachment C of the Supplemental Phase II SOW. Additional

stormwater piping information associated with the Hill 78 Site has been included as Attachment B to this report.

4.4 Source of PCDFs

In the Supplemental Phase II SOW, GE proposed to provide a clarification, to the extent possible based on existing

data, regarding the source of PCDFs detected in soil, how PCDFs are related to the presence of PCBs, and the

potential interference by polychlorinated diphenyl ethers (PCDEs) on the detection of PCDFs.

BLASLAND, BOUCK & LEE, INC. SYR-F\usERaMCGi\DMN9A3997i550.wPD-.7/31/97 engineers t scientists 4-3

PCB Aroclors contain a small fraction of PCDFs; "pure" Aroclor contains approximately 2 to 20 ppm PCDFs

(EPRI, 1985; Wakimoto, et. al., 1988). PCDFs were detected in certain soil samples at the Allendale School

Property at concentrations that are higher than would be expected to be present given the PCB concentrations found.

Although the PCDFs were found in fill material, the source of the PCDFs detected in the fill is unknown.

As for the issue concerning PCDEs, during an analysis for PCDFs, PCDEs are often detected at the same time as

PCDFs and in some cases cannot be distinguished from PCDFs. Thus, in such cases, the presence of PCDEs can

give a false-positive measurement of PCDFs.

BLASLAND, BOUCK & LEE, INC. SYR-F\uSERS\MCGi\DMN9A3997i550WPD-7/3ifl7 engineers & scientists

5. Additional Data Needs /Additional Investigations

Several items that require additional investigations are discussed below; the locations of proposed future

investigations to address these data needs are shown on Figure 11.

5.1 Additional Soil Borings Within the Capped Area

Several of the soil borings collected to date have shown elevated PCB concentrations at the lowest depth interval

sampled. To further delineate the vertical extent of PCBs in subsurface soils, nine additional soil borings will be

located within the southern portion of the capped area, in areas where the previous borings did not completely

delineate the vertical extent of PCBs (Figure 11). Soil samples will be obtained from 2-foot depth intervals

beginning at the base of the cap, extending through the fill/original soil. Representative samples will be collected,

and all samples collected from above the fill/original grade interface will be analyzed for PCBs. Additional sample

depths will be analyzed sequentially for PCBs until the deepest increment shows a non-detectable concentration

of PCBs or two successive depth increments indicate PCB concentrations less than 1 ppm. All soil samples will

be screened for VOCs with a PID, and any samples with a screening result greater than 10 PID units will be

submitted for Appendix IX+3 analysis. Following sampling, the boreholes will be repaired in a manner similar

to the methods used previously.

5.2 Additional Soil Borings Near ASB-3

The soil sample taken from the 3- to 5-foot depth interval at ASB-3 detected several Appendix IX+3 constituents.

To further characterize the soil near this soil boring, three soil borings will be installed approximately 20 feet to

the north, west, and south of ASB-3. Soil samples will be collected from the 0- to 6-inch and 6- to 12-inch depth

intervals, and thereafter in 2-foot increments to a depth of 7 feet. All samples will be analyzed for PCBs. In

addition, subsurface samples (i.e., greater than 2 feet) will be analyzed for Appendix IX+3 constituents. The

surface and near-surface samples will be screened for VOCs with a PID; any samples with a screening result greater

BLASLAND. BOUCK & LEE, INC. SYR-F:\USERS\MCG l\DMN9A39971550 WPD - 7/31/97 engineers & scientists 5-1

than 10 PID units will also be submitted for Appendix IX+3 analysis. In addition, as explained in Section 5.3

below, regardless of PID screening results, one of these surficial samples will be submitted for Appendix IX+3

analysis.

5.3 Presence of Non-PCB Hazardous Constituents in Surface Soils Outside of Capped Area

In previous investigations, those soil samples analyzed for Appendix IX+3 constituents have focused on the deeper

sample depth intervals. As a result, samples have not been collected from the surficial soils for analysis of

Appendix IX+3 constituents. To address this data need, GE proposes to collect seven surficial soil samples from

areas outside the capped area. Two samples will be taken from the southwestern side of the area, within 25 feet

of former soil boring locations ASB-1 and ASB-2. Three samples will be taken from the eastern side of the area,

within 25 feet of former soil boring locations ASB-5, ASB-11, and SCH-2, respectively. One sample will be taken

from the northwestern side of the capped area, within 25 feet of the former soil boring location ASB-4. The soil

samples will be taken from the 0- to 6-inch depth interval in accordance with criteria set forth in the SAP/DCAQAP

and will be analyzed for Appendix IX+3 constituents. In addition, one of the 0- to 6-inch samples taken from the

vicinity of ASB-3 will also be submitted for Appendix IX+3 analysis.

5.4 Resolution of Groundwater Contours

The groundwater table contours developed in this report are anomalous; the data obtained from well SCH-2 may

have skewed the contour interpretation. A depression is indicated in this area, draining to the south along the west

side of the Hill 78 area. In addition, the location of NY-4 at the top of a hill near the west side of the site results

in a difficult interpretation of groundwater contours at the southwest corner of the site. To better determine the

shape of the groundwater table surface at this site, four temporary piezometers will be installed, and groundwater

elevations measured. One piezometer will be installed in the vicinity of the southwest corner of the site, one

piezometer will be installed at the former soil boring location ASB-5, and two piezometers will be installed

approximately 150 feet to the west and southeast of existing monitoring well SCH-2. Concurrent with water level

BLASLAND, BOUCK & LEE. INC. SYR-F:\usERaMCGi\DMN9A3997i550WPD-7flifl7 engineers & scientists 5-2

measurements taken at the piezometers, water table elevations will also be measured at existing monitoring wells

SCH-1 through SCH-4, well NY-4, well 78-1, and well 78-6. Water level measurements taken for the site will be

collected concurrently with water level measurements proposed for the adjacent Hill 78 site so that groundwater

contours that cross the boundary between the sites may be better defined.

6. Schedule for Future Activities

Following MDEP review and approval of this Supplemental Phase II Report, GE will initiate the proposed field

activities. Once the results of these efforts are received, and it is determined that the identified data needs have

been adequately addressed, GE will prepare an addendum to this report. The addendum will summarize the recent

investigations and, where appropriate, incorporate the existing information and provide updated evaluations.

Concurrent with the above-referenced addendum, GE will prepare a Risk Characterization SOW proposal to

evaluate (in accordance with the MCP) potential risks to human health and the environment.

The addendum and Risk Characterization SOW will be submitted to the MDEP within six months following the

MDEP approval of this report.
