Former Elco Dress Company Property 1-1 Permanent Solution with No Conditions

1.0 INTRODUCTION

TRC Environmental Corporation (TRC) has completed the following Permanent Solution with No

Conditions Statement (PSS) for submittal to the Massachusetts Department of Environmental

Protection (MassDEP), on behalf of the City of New Bedford (City) through the City’s Department

of Environmental Stewardship. The PSS was prepared per the Massachusetts Contingency Plan

(MCP; 310 CMR 40.0000) for the subject property commonly known as the Former Elco Dress

Company Property located at Assessor’s Map 98, Lots 261 & 264 (330 Collette Street; the “Site”)

in New Bedford, Massachusetts and documents closure of the portion of the Site administratively

tracked under Release Tracking Number (RTN) 4-27151 (i.e., the “Disposal Site”). A Site location

map is included as Figure 1.

Previous response actions associated with the former presence of an underground storage tank

(UST) and resulting subsurface petroleum impacts (i.e., C11-C22 aromatic hydrocarbons detected

in soil in excess of MassDEP Reportable Concentrations [RCs]) were conducted at the property

under RTN 4-20272, which achieved closure with the submittal of a Class A-2 Response Action

Outcome (RAO) Statement in June 2008 (Tighe & Bond, 2008).

This PSS applies to the entire Site, a portion of which was impacted by Disposal Site-related Oil

and/or Hazardous Material (OHM), specifically the presence of low concentrations of lead in

groundwater in the vicinity of overburden monitoring well TRC-16, unrelated to the former UST

and associated release. A Site plan, including a depiction of the portions of the property within and

beyond the limits of the Disposal Site as defined for this PSS, is shown on Figure 2.

This report is subject to the limitations included in Appendix A.

1.1 Release Background

The following provides a summary of the Site history, previous environmental investigations and

responses actions conducted at the property on behalf of the City by others, and the results of the

recent due diligence investigation conducted at the property by TRC on behalf of the City.

1.1.1 Site History

The Site located at Assessor’s Map 98, Lots 261 & 264 (330 Collette Street) was historically

occupied by an abandoned four-story mill building (“main building”), including a basement, and

two secondary buildings including a two-story engine room and a single-story boiler house (Tighe

& Bond, 2008). The Former Elco Dress Company Property is understood to have previously

operated as a textile mill following construction in 1909 and tenants included the New Bedford

Cotton Mills Corporation, Hoosac Mills Corporation and Elco Dress Company (Tighe & Bond,

2008). A Site location map is included as Figure 1.

The buildings became vacant in the early 1990s and the City subsequently removed asbestos-

containing materials (ACM) and other hazardous materials, including a 20,000-gallon fuel oil

UST, from the property prior to the demolition of the main and secondary buildings and subsequent

grading of the property in 2008. The property has remained vacant following demolition. Select


historic figures depicting past Site features (e.g., former buildings, former UST location,

approximate fill pipe locations, etc.) are included as Appendix B for ease of reference.

The Site abuts the former Payne Cutlery Corporation property (Payne Property) located to the

south at 295 Phillips Avenue (Assessor’s Map 98, Lot 3). As described in detail in the Phase II

Comprehensive Site Assessment (CSA) Addendum (TRC, 2017a) dated April 2017, two

MassDEP RTNs are associated with the Payne Property (i.e., RTN 4-00404 and RTN 4-15373).

The Payne Property was previously in default relative to Tier Classification obligations under the

MCP for both RTNs prior to submission of the Interim Phase II CSA in September 2015 (TRC,

2015), at which point a Tier Classification was submitted in accordance with 310 CMR 40.0500

of the MCP. Data generated up to the date of the Phase II CSA Addendum are sufficient to

characterize the nature and extent of impacts at the Payne Property, subject to the limitations and

data gaps described in the Phase II CSA Addendum. Activities within the Payne Property have

not impacted the Site.

1.1.2 Response Actions Undertaken by Others

Detailed descriptions of investigative activities and response actions conducted at the Site by

others are included in the following reports:

▪ Underground Storage Tank Closure Report (Tighe & Bond, 2006);

▪ Letter From Tighe & Bond to MassDEP Regarding Response to Notice of Responsibility

(NOR) dated May 14, 2007 (Tighe & Bond, 2007); and

▪ Class A-2 RAO Statement (Tighe & Bond, 2008).

The following summarizes investigation and remedial activities performed at the Site by others.

Historic soil and groundwater sample analytical results associated with the property are

summarized in Table 1 and Table 2, respectively.

1.1.2.1 Previous Investigation Activities by Others

Environmental assessment activities at the Site have primarily been limited to a Phase I

Environmental Site Assessment (ESA) conducted by Cygnus Group, Incorporated (Cygnus) in

May 2000 and in association with removal of a UST as documented in the Class A-2 Response

RAO Statement submitted by Tighe & Bond, Incorporated (Tighe & Bond) in January 2008. A

Utility-Related Abatement Measure (URAM) was also completed by NSTAR in 2007 in support

of building demolition activities (NSTAR, 2007). The URAM was limited to the “cutting and

capping” of the existing subsurface natural gas service to the property.

The Phase I ESA included property reconnaissance, file reviews and limited subsurface

investigation activities including the installation of five soil borings (i.e., CGW-1 through CGW-

5) completed as monitoring wells (Tighe & Bond, 2007). The limited subsurface investigation

included the collection of five soil samples (i.e., one from each soil boring) and one duplicate

sample from depths of 10 to 12 feet below ground surface. The soil samples were analyzed for

volatile organic compounds (VOCs), volatile petroleum hydrocarbons (VPH), extractable

petroleum hydrocarbons (EPH), metals, and/or polychlorinated biphenyls (PCBs). Each of the


monitoring wells was also sampled in 2000 for the presence of VOCs, VPH, EPH and/or dissolved

metals. Based on the results of soil and groundwater analytical data, the Phase I ESA concluded

that concentrations of OHM did not exceed applicable RCs under the MCP (Tighe & Bond, 2007).

The Phase I ESA also identified two 275-gallon USTs within the basement of the main building,

and an adjacent property (i.e., 229 Coffin Avenue; My Bread Products Company) was recognized

for former transformer oil and gasoline releases (RTN 4-10412) in 1991; however, the 20,000-

gallon UST and associated release noted below were not identified in the Phase I ESA. The two

275-gallon USTs in the basement of the former main building are understood to have been

removed during building demolition and grading activities completed in 2008.1 Based on the

location of the former fill pipes, previous environmental investigation activities within the

footprints of both the Former Elco Dress Company property and nearby Payne Property have not

identified significant petroleum impacts associated with the 275-gallon USTs. The Phase I ESA

concluded that there were no reportable conditions present at the Site (Tighe & Bond, 2007).

1.1.2.2 Previous Investigation Activities at Payne Property

Environmental assessment activities were also conducted on the adjacent Payne Property between

1987 and 2015, including environmental investigation activities aimed at evaluating the potential

for impacts to have migrated from the Site to the Payne Property. As documented in the Phase II

CSA Addendum for the Payne Property (TRC, 2017a), soil and groundwater sampling was

conducted in 1987 and 2000 within portions of the Former Elco Dress Company Property in

support of the environmental assessment of the Payne Property included the following:

• In 1987, three soil borings (i.e., MW-3, MW-3A and MW-4) were advanced and soil

samples were collected from various depths within each boring for VOCs, total

petroleum hydrocarbon (TPH), Toxicity Characteristic Leaching Procedure (TCLP)

metals and/or PCB analysis. Each soil boring was completed as a monitoring well and

groundwater samples were subsequently collected for VOCs and dissolved metals.

• In 2000, two soil borings (i.e., SB-1 and SB-2) and one surface soil sample (i.e., SS-01

collected from 0 to 1 foot below ground surface) were installed and sampled for VOC,

VPH, EPH, and/or metals analysis. Soil borings SB-1 and SB-2 were completed as

monitoring wells adjacent to Collette Street. Two additional monitoring wells (i.e.,

EMW-1 and EMW-2) were also installed. The four monitoring wells underwent sampling

for VOCs, VPH, EPH, and dissolved metals in March 2000.2

With the following exceptions, no elevated concentrations of contaminants of potential concern

(COPCs) were detected in the soil or groundwater samples collected in 1987 and 2000 from the

Site relative to the regulatory criteria at the time of sampling:

• Dissolved cadmium (8.0 micrograms per liter [µg/L]) detected in monitoring well MW-3

in 1987.

1 Approximate former fill pipe locations are depicted in one or more figures include herein as Appendix B. 2 Groundwater analytical results collected from monitoring well EMW-2 were unavailable as of the submittal of this

PSS.


• Trichloroethylene (TCE; 26 µg/L) detected in monitoring well MW-4 in 1987.

• Dibenzo(a,h)anthracene (1.4 milligrams per kilogram [mg/kg]) detected in soil sample

SS-01 collected in 2000.

• TCE (20 µg/L) detected in monitoring well EMW-1 in 2000.

With the exception of recent due diligence activities described in Section 1.1.3, no additional

environmental assessment activities have been completed on the Site since submittal of the Class

A-2 RAO Statement in January 2008. Table 1 and Table 2 summarize the historic soil and

groundwater analytical results, respectively.

1.1.2.3 Previous Response Actions by Others

As documented in the UST Closure Report (Tighe & Bond, 2006), one 20,000-gallon steel No. 4

fuel oil UST was removed from the Site in advance of building demolition activities. Post-removal

soil sidewall and excavation bottom samples exhibited concentrations of C11-C22 aromatic

hydrocarbons in excess of RCs for soil (Tighe & Bond, 2007). Following evaluation of the

laboratory analytical results, it was determined that a release of No. 4 fuel oil had occurred at the

Site. Upon obtaining knowledge of the 120-day reportable release condition, the City notified the

MassDEP and RTN 4-20272 was assigned.

The fuel oil release was determined to have impacted a volume of soil proximate to the former

UST measuring approximately 40 feet by 30 feet by 13 feet deep (Tighe & Bond, 2008). Residual

contamination in soil was determined to be below MCP Method 1 standards, but above

background, and groundwater was found to be unimpacted by the fuel oil release (Tighe & Bond,

2008). As a result, a Class A-2 RAO Statement was submitted to MassDEP on behalf of the City

in January 2008 (Tighe & Bond, 2008).

1.1.3 Due Diligence Activities Undertaken by the City

The following summarizes investigations performed at the Site by TRC on behalf of the City. Due

diligence activities were conducted in accordance with an United States Environmental Protection

Agency (EPA) approved Quality Assurance Project Plan (QAPP) Addendum dated August 2017

(TRC, 2017b) and a Site-Specific Health and Safety Plan (HASP).

The objective of the due diligence investigation was to evaluate surface and subsurface conditions

at the Site in support of risk characterization and the future transfer of the property. The

environmental investigation activities consisted of additional data collection, data evaluation, and

associated documentation as described herein.

1.1.3.1 Soil Investigation

Soil boring locations were selected at the Former Elco Dress Company Property to evaluate current

surface and subsurface soil conditions throughout the property, including the horizontal and

vertical extent of potential impacts (e.g., VOCs, EPH, metals and/or PCBs). As no reportable

conditions were identified in the Phase I ESA and limited impacts related to the No. 4 fuel oil


release were previously addressed as described in the Class A-2 RAO Statement (Tighe & Bond,

2008), soil boring locations were selected to provide general areal coverage throughout the

property, target potential impacts related to known past on-property activities and uses (e.g., USTs,

former tank fill lines, former structures, former transformers, etc.), and evaluate previous analytical

detections in soil and groundwater. A summary of the soil boring, as well as monitoring well,

location rationale is provided in Table 3.

Following utility clearance activities (i.e., Dig Safe® notification), a total of ten (10) soil borings

(i.e., Elco-SB-1 through Elco-SB-10) were advanced using direct push (GeoProbe®) methods

including a 6600 truck-mounted drill rig on October 19, 2017. Soil borings were advanced until

refusal or borehole collapse was encountered, which prevented the achievement of greater depths.

The bedrock surface, estimated to be as deep as approximately 30 feet below grade, was not

encountered during the drilling activities. When shallow refusal was encountered (i.e., above the

targeted sample depth(s)) unrelated to the bedrock surface, multiple attempts at an individual soil

boring location were made to reach the desired total depth. In addition, three (3) surface soil

samples (i.e., Elco-SS-1 through Elco-SS-3 from 0 to 1 foot below ground surface) were manually

collected using hand tools (e.g., stainless steel hand auger) on October 20, 2017. Soil boring

locations are depicted in Figure 2.

During the advancement of soil borings, the soil material was visually examined and screened in

the field for VOCs using the MassDEP jar headspace method. Immediately upon collecting the

sample, a photoionization detector (PID) was passed over the surface of the sample and any organic

vapor readings above background were noted. Field screening PID results (jar headspace method)

ranged from background (0.0 parts per million by volume [ppmv]) to 2.4 ppmv. At locations where

VOC analyses were required, samples were immediately and carefully placed (in a manner to

minimize volatilization potential) in preserved vials upon collection, and then immediately placed

on ice.

TRC’s soil boring logs (Appendix C) generally indicated the presence of limited organic topsoil

overlying fine to coarse sand with varying amounts of silt and gravel. This is consistent with the

United States Geological Survey (USGS) surficial geology map for northern New Bedford which

depicts the Site within a zone of glacial till and moraine deposits identified as a “thin till” unit

(USGS, 2011). The thin till is described as a non-sorted, non-stratified matrix of sand, some silt

and little clay containing scattered gravel clasts and few large boulders. The material is loose to

moderately compact and may contain both ablation (looser, coarser grained) and lodgement till

(more compact, finer grained) facies (USGS, 2011). Based on gauging of newly installed

monitoring wells in October 2017, the water table was encountered between approximately 5 and

10 feet below the top of the well riser.

Limited shallow soil volume (0-3 feet below ground surface [bgs] as location Elco-SB-2) within

the footprint of the former mill building (i.e., “main building”) was submitted for analysis as it is

understood that the property was filled/graded following building demolition. Soil samples were

generally collected at a deeper location above the native soil horizon (i.e., primarily from

approximately 5-7 feet bgs) within the footprint of the former mill building, with the retention of

deeper “hold” samples. The actual sample depths were dependent on property-specific field

conditions including, but not limited to, the observation of fill material, staining, odors, elevated


PID measurements (or lack thereof), and the depth of the water table. The final sample depths were

determined in the field in consultation with the Project Geologist and/or LSP. In addition, the three

(3) previously noted surface soil samples (0 to 1 foot below ground surface) were collected along

the perimeter of the former mill building consistent with the approved QAPP Addendum (TRC,

2017b).

Within other portions of the property (i.e., former secondary buildings including the “Engine

Room” and “Boiler House,” former courtyard and 20,000-gallon UST area), soil samples were

generally collected from near the ground surface (i.e., 0-3 feet bgs) and at a deeper location above

the native soil horizon (i.e., approximately 5-7 feet below grade), with the retention of deeper

“hold” samples. The actual sample depths were dependent on property-specific field conditions

discussed in detail with the Project Geologist and/or LSP.

For those soil boring locations in which shallow (i.e., 0-3 feet bgs) samples were collected and

analyzed for PCBs (i.e., Elco-SB-2, Elco-SB-7 and Elco-SB-10) the deeper location above the

native soil horizon (i.e., 5-7 feet bgs) were submitted to Con-Test on “hold” pending LSP review

of the 0-3 feet bgs sample results. Con-Test was instructed to “extract and hold” deeper samples

for potential PCB analysis to ensure as-needed analyses could be authorized within the method-

specific holding times. Based on the shallow soil sample PCB results, authorization of the deeper

“hold” samples was determined to be unnecessary.

In addition, the soil boring program included retention of deeper “native” soil material for as

needed laboratory EPH and metals analysis contingent upon receipt and review of results

associated with upper (i.e., shallow) horizon soil samples. The contingency samples were

submitted to Con-Test on “hold” pending LSP review of the upper horizon soil analytical results.

Con-Test was instructed to “extract and hold” samples for potential EPH analysis to ensure as-

needed analyses could be authorized within the method-specific holding times. Based on the

shallow soil sample EPH and metals results, authorization of the deeper “hold” samples was

determined to be unnecessary.

Given the 14-day holding time for VOCs, no samples targeted for VOC analysis were held by the

laboratory to avoid potential analysis outside of the prescribed holding time and data quality issues.

TRC relied on field observations and field screening results in consultation with the Project

Geologist and LSP to determine the need to analyze samples from deeper soil horizons for VOCs.

Prior to mobilization to the field, TRC was prepared to collect additional sample volume for VOC

analysis should it be determined that such samples, beyond those identified in the QAPP, were

necessary to adequately complete the scope of work. No additional sample volume, beyond that

proposed in the QAPP, was collected during the due diligence investigation.

With the exception of those samples targeted for VOC analysis (previously noted), soil recovered

from each targeted depth interval was placed into stainless steel bowls using stainless steel spoons

(all equipment decontaminated properly prior to use) and subsequently homogenized. The

homogenized samples were subsequently transferred to laboratory-supplied containers with a

stainless-steel spoon and immediately placed on ice.


Soil samples were submitted for laboratory VOC, EPH, MCP-14 metals and/or PCB analysis. All

soil samples, including duplicates, were submitted to Con-Test Analytical Laboratory (Con-Test)

of East Longmeadow, Massachusetts under proper chain-of-custody. Soil sample analytical results

are summarized in Table 4.

VOCs and PCBs were not detected above laboratory reporting limits in soil samples collected

during the due diligence investigation. Selected EPH ranges and pyrogenic and petrogenic

polycyclic aromatic hydrocarbons (PAHs) were detected at low concentrations (i.e., below

MassDEP RCs) in soil samples Elco-SB-8 (0-3’), Elco-SB-9 (0-3’), Elco-SB-9 (8-10’), Elco-SB-

10 (0-3’) as well as the associated duplicate sample, Elco-SS-2 (0-1’), and Elco-SS-3 (0-1’). In

addition, select metals including arsenic, barium, cadmium, chromium, lead, mercury, nickel,

vanadium and/or zinc were detected in each of the soil samples collected in October 2017 at low

concentrations (i.e., below MassDEP RCs).

Excess soil volume associated with the drilling activities was returned to their place of origin

(placed back inside the boring) in approximately the order in which it was removed. Based on the

PID and visual observations, further handling and disposal (e.g., off-site disposal as hazardous

wastes) was not required.

Soil borings were located in the field by a licensed surveyor (Land Planning, Incorporated [Land

Planning] of Hansen, Massachusetts) and added to the existing electronic base map as depicted in

Figure 2.

1.1.3.2 Groundwater Investigation

As there were no on-property monitoring wells, a total of four (4) of the soil borings (i.e., Elco-

SB-2, Elco-SB-3, Elco-SB-7, and Elco-SB-10) were completed as shallow monitoring wells using

direct push (GeoProbe®) methods (Appendix C). Newly installed monitoring well locations TRC-

14, TRC-15, TRC-16, TRC-17 were located in the field by a licensed surveyor (i.e., Land

Planning) and are depicted on Figure 2. The survey included the ground, top of riser and top of the

protective casing elevation at each monitoring well point.

The four groundwater monitoring wells were constructed of two-inch diameter Schedule 40

polyvinyl chloride (PVC) to total depths of approximately 15 feet bgs each. The pipe sections

were threaded screw type, eliminating the need for solvent-based glue. Each monitoring well was

constructed with a 10-foot (0.010-inch machine slotted) screen sections placed so as to extend

above and below the upper surface of the water table. A sand pack was placed around the screen

extending to a level approximately two feet above the top of the screen. A bentonite seal,

approximately two feet thick, was placed above the sand pack in order to seal off the screened

portion of the well from the overlying strata. The remainder of the well annulus was filled with

soil cuttings to ground surface. The newly installed monitoring well(s) were completed with a

stickup pipe due to the presence of vegetation at the Site. Monitoring well locations are depicted

on Figure 2.

The newly-installed wells were subsequently developed by removing at least three well volumes

by purging with a submersible pump. Headspace measurement of VOCs were made on the purged


groundwater using a PID. Per the approved QAPP Addendum, since the headspace VOC readings

were less than 10 ppmv and no significant sheens or chemical odors are noted, the well development

water was returned to the ground surface consistent with the MCP (310 CMR 40.0045(7)).

Following well development and an equilibration period of approximately 1.5 weeks, the newly

installed monitoring wells were gauged to identify the depth to water and potential presence of

non-aqueous phase liquid (NAPL). No NAPL was detected in association with the newly installed

monitoring wells and gauging results are summarized in the following table.

Following the well development process, TRC collected groundwater samples from the newly-

installed monitoring wells to evaluate groundwater conditions at the Site. One round of

groundwater samples was collected on October 31, 2017. Samples were obtained using low-flow

sampling techniques with an adjustable rate submersible pump. Samples were submitted to Con-

Test for VOC, EPH, and total metals analysis. A dissolved metals aliquot was also collected in the

field at each monitoring well location. The samples were field filtered using a 0.45-micron (µm)

filter and held by the laboratory pending receipt and review of the total metals results in

groundwater. Based on the total metals results, select dissolved metals were individually analyzed

at the discretion of the LSP as noted below.

Groundwater analytical results from October 2017 are summarized in Table 5. VOCs were not

detected in any of the groundwater samples, including the field duplicate, at concentrations in

excess of laboratory reporting limits. A low (i.e., less than MassDEP RCs) concentration of C19-

C36 aliphatic hydrocarbons (180 micrograms per liter [µg/L]) was detected in monitoring well

TRC-16; however, no additional EPH ranges or PAHs were detected in the groundwater samples

in excess of laboratory reporting limits. Several metals including antimony, arsenic, barium,

beryllium, chromium, lead, mercury, nickel, thallium, vanadium and/or zinc were detected in each

of the groundwater samples. With the exception of lead, the detected concentrations of total metals

were less than MassDEP RCs.

Total lead was detected in monitoring well TRC-16 at a concentration of 36 µg/L. Noting a stable,

but elevated turbidity reading of 136 nephelometric turbidity units (NTUs) at the time of sample

collection, the laboratory was authorized to analyze the dissolved aliquot for lead. As indicated in

Table 5, the dissolved concentration of lead in monitoring well TRC-16 (12 µg/L) was slightly

above the RCGW-2 criteria. This result was confirmed by the laboratory.


Per 310 CMR 40.0315(1) of the MCP, the detection of lead in groundwater in excess of one or

more RCs represents a 120-day reporting condition. The detection and subsequent notification

related to the presence of lead in monitoring well TRC-16 is the subject of this PSS.

1.2 Objective

TRC completed this PSS in accordance with 310 CMR 40.1056 (Content of Permanent Solution

association with the Interim Phase II CSA for the Payne Property (TRC, 2015) to screen for

significant data quality issues and confirm or reject certain suspect data. Applicable soil samples

collected from the subject property by others are appropriately referenced in the data usability

assessment (DUA) in Section 4.0 and Appendix D.


2.0 PERMANENT SOLUTION WITH NO CONDITIONS SUPPORTING

DOCUMENTATION

2.1 Disposal Site Location Description – 310 CMR 40.1056(2)(a)

As detailed in Section 1.1.3.2, during due diligence investigation activities in October 2017, lead

(dissolved) was detected in monitoring well TRC-16 (12 µg/L) at a concentration slightly above

the RCGW-2 criteria (10 µg/L). The detected concentration of lead triggered a 120-day reporting

obligation pursuant to 310 CMR 40.0315(1). TRC informed the City of the notification

requirement and the 120-day reporting condition was reported to the MassDEP by the City on

March 15, 2018. MassDEP subsequently assigned RTN 4-27151 to the Disposal Site.

The Disposal Site, tracked by RTN 4-27151 encompasses an area in the vicinity of Collette and

Church Streets in New Bedford, Massachusetts. The subject of this PSS is the approximately 1.91-

acre vacant property located at Assessor’s Map 98, Lots 261 and 264. There are no occupied

buildings located at the Site. The property is bordered to the north by Collette Street and an active

bakery distribution building at 306 Collette Street, to the west across Church Street by commercial

greenhouses, to the south by the Payne Cutlery Disposal Site (RTN 4-15373 and associated RTN

4-00404), and to the east by residential properties. A Site Location Map is provided as Figure 1.

The Universal Transverse Mercator (UTM) coordinates for the Site subject to this PSS are

4,614,107 meters north and 339,103 meters east in Zone 19. The latitude and longitude of the Site

are 41.662480 latitude and -70.932565 longitude.

Observation of regional soils and review of historic topographic maps indicates that the surficial

geology consists of glacial outwash sediments. The USGS surficial geology map for northern New

Bedford depicts the Site within a zone of glacial till and moraine deposits identified as a “thin till”

unit (USGS, 2011). The thin till is described as a non-sorted, non-stratified matrix of sand, some

silt and little clay containing scattered gravel clasts and few large boulders. The material is loose

to moderately compact and may contain both ablation (looser, coarser grained) and lodgement till

(more compact, finer grained) facies (USGS, 2011).

There are no surface water bodies at the subject property. Wetland areas and associated surface

water bodies exist greater than 500-feet west-northwest of the subject property as indicated in

Figure 3. The Site is not within the 100-year or 500-year flood plains and flooding potential

appears to be low

Site Boundary. The location and boundaries of the Disposal Site within the subject property to

which this PSS applies are illustrated on Figures 2.

Proximity to Environmental Resources. The Site’s proximity to environmental resources is

illustrated on Figure 3, which presents a MassDEP Priority Resources Map with five hundred foot

and one half-mile radii as measured from the Site.

Property Owner. The Site property, including Assessor’s Map 98, Lots 261 and 264, is currently

owned by the City of New Bedford. A small (0.01 acre) property located immediately west of Lot


264 (i.e., Assessor’s Map 98, Lot 262) is currently listed under the ownership of Commonwealth

Electric Company by the City’s Assessor’s Office.

Site Use and Area Land Use. The property was historically occupied by an abandoned four-story

mill building (“main building”), including a basement, and two secondary buildings including a

two-story engine room and a single-story boiler house (Tighe & Bond, 2008). The Former Elco

Dress Company Property is understood to have previously operated as a textile mill following

construction in 1909 and tenants included the New Bedford Cotton Mills Corporation, Hoosac

Mills Corporation and Elco Dress Company (Tighe & Bond, 2008). A Site location map is included

as Figure 1.

The buildings became vacant in the early 1990s and the City subsequently demolished the main

and secondary buildings and graded the property in 2008. The property has remained vacant,

consisting primarily of low vegetation, following the demolition.

Institutions. The Taber Mill senior and disabled adult apartment complex, located approximately

350-feet south-southwest of the Disposal Site, is considered an institution in accordance with 310

CMR 40.0006 of the MCP.3

Residential Population. An estimated 3,900 people reside within a ½-mile radius of the Site.

This estimate is based on community profile data for the City of New Bedford obtained from the

Massachusetts Department of Housing and Community Development (DHCD) website

https://www.mass.gov/orgs/housing-and-community-development.

Drinking Water Source Areas. Based on review of the MassDEP Priority Resources Map (see

Figure 3), the Site is not located within a Zone II or Zone A of a drinking water supply area, an

Interim Wellhead Protection Area (IWPA), or a potentially productive aquifer (PPA).

Public/Private Wells. No private or non-municipal public wells are located within 500 feet of the

Site. There are no municipal wells located within 1,000 feet of the Site.

Environmental Receptors. The Site is located in an industrial and residential area of New

Bedford, Massachusetts. There is no surface water or wetland habitat at the Site. The nearest

water body is a wetland located approximately 750 feet west of the Site. The Acushnet River is

located approximately 2,700 feet to the east of the Site. There are no endangered species habitats,

Areas of Critical Environmental Concern (ACECs) and/or certified vernal pools within 500 feet

of the Site.

2.2 Conceptual Site Model – 310 CMR 40.1056(2)(b)

The Site is situated in an industrial and residential area of New Bedford, Massachusetts. The

property was historically occupied by an abandoned four-story mill building, including a

basement, and two secondary buildings including a two-story engine room and a single-story boiler

house. Prior to demolition and grading in 2008, these structures formerly occupied the majority of

the footprint of the Map 98, Lot 261 and 264 parcels. With the exception of the limited release

from the former 20,000-gallon steel No. 4 fuel oil UST and subsequent response actions, no known

releases or threats of release are known to have occurred at the Site.

The following provides a succinct description of the conceptual site model (CSM) and potential

source of the localized detection of dissolved lead in shallow groundwater subject to this PSS.

2.2.1 Disposal Site History

As described in Section 1.1, phased environmental investigation activities and responses actions

have occurred intermittently at the property since 2000. The Phase I ESA conducted in May 2000

included property reconnaissance, file reviews and limited subsurface investigation activities and

concluded that concentrations of OHM did not exceed applicable RCs under the MCP (Tighe &

Bond, 2007). The Phase I ESA did identify two 275-gallon USTs within the basement of the main

building; however, the two former 275-gallon USTs are understood to have been located cross-

gradient to the detection of lead in monitoring well TRC-16 that is the subject of this PSS and the

USTs were removed during building demolition and grading activities completed in 2008.

Environmental assessment activities were also conducted on the adjacent Payne Property between

1987 and 2015, including environmental investigation activities aimed at evaluating the potential

for impacts to have migrated from the Site to the Payne Property. With the exceptions of limited

detections of dibenzo(a,h)anthracene in soil and cadmium and TCE in groundwater, no elevated

concentrations of COPCs were detected in the soil or groundwater samples collected in 1987 and

2000 from the Site relative to the regulatory criteria. Furthermore, elevated concentrations of

VOCs, PAHs, and cadmium were not detected during the recent investigations activities conducted

by TRC on behalf of the City.

As documented in the UST Closure Report (Tighe & Bond, 2006), one 20,000-gallon steel No. 4

fuel oil UST was removed from the Site in advance of building demolition activities. Post-removal

soil sidewall and excavation bottom samples exhibited concentrations of C11-C22 aromatic

hydrocarbons in excess of RCs for soil (Tighe & Bond, 2007). The fuel oil release was determined

to have impacted a volume of soil proximate to the former UST measuring approximately 40 feet

by 30 feet by 13 feet deep (Tighe & Bond, 2008). Residual contamination in soil was determined

to be below MCP Method 1 standards, but above background, and groundwater was found to be

unimpacted by the fuel oil release (Tighe & Bond, 2008). As a result, a Class A-2 RAO Statement

was submitted to MassDEP on behalf of the City in January 2008 (Tighe & Bond, 2008).

Recent environmental investigation activities conducted by TRC on behalf of the City confirmed

that VOCs and PCBs were not detected above laboratory reporting limits in soil samples. Select

EPH ranges, pyrogenic and petrogenic PAHs, and metals (i.e., arsenic, barium, cadmium,

chromium, lead, mercury, nickel, vanadium and/or zinc) were detected at low concentrations (i.e.,

below MassDEP RCs) in a limited number of soil samples. Similarly, VOCs were not detected in

any of the groundwater samples, including the field duplicate, at concentrations in excess of

laboratory reporting limits. A low (i.e., less than MassDEP RCs) concentration of C19-C36 aliphatic

hydrocarbons (180 micrograms per liter [µg/L]) was detected in monitoring well TRC-16;

however, no additional EPH ranges or PAHs were detected in the groundwater samples in excess


of laboratory reporting limits. Several metals including antimony, arsenic, barium, beryllium,

chromium, lead, mercury, nickel, thallium, vanadium and/or zinc were detected in each of the

groundwater samples; however, with the exception of dissolved lead in TRC-16, the detected

concentrations of metals (total) were less than MassDEP RCs.

Considering the Site history, including former mill operations, subsequent demolition activities,

results of prior environmental investigations, completed response actions related to a limited UST

release, and the results of recent soil and groundwater due diligence investigation, the presence of

dissolved lead detected in monitoring well TRC-16 appears to be isolated (i.e., not related to any

known or potential release or threat of release as defined by the MCP) and unrelated to any prior

release reported at the Site. Rather, the presence of dissolved lead in TRC-16 (12 µg/L) at a

concentration slightly above the RCGW-2 criteria of 10 µg/L is likely related to the stable, but

elevated turbidity in the monitoring well at the time of sample collection, the presence of limited

shallow demolition debris observed at the property, or a combination thereof. As indicated in the

boring logs for locations throughout the property, anthropogenic materials including glass,

clinkers, brick, etc. are present in limited quantities in the shallow subsurface. The presence of

such materials could contribute to the presence of metals, including lead, detected at low

concentrations in the shallow groundwater.

2.2.2 Disposal Site Specific Chemicals of Concern

Elevated concentrations of VOCs, PCBs, EPH ranges/PAHs, and metals are not present in soil at

the Site. Similarly, elevated concentrations of VOCs and EPH ranges/PAHs are not present in

groundwater at the Site. With the exception of lead, the detected concentrations of metals at the

Site are also low (i.e., less than MassDEP RCs). Total lead was detected in monitoring well TRC-

16 at a concentration of 36 µg/L and the dissolved concentration of lead in monitoring well TRC-

16 (12 µg/L) was slightly above the RCGW-2 criteria, resulting in the 120-day reportable condition

associated with RTN 4-27151. No additional Site-specific COPCs are associated with the Disposal

Site.

2.3 Elimination or Control of OHM Sources and Control of OHM Subsurface

Migration– 310 CMR 40.1056(2)(c) and 310 CMR 40.1056(2)(d)

The following discusses the work undertaken and completed by the City at the Site.

2.3.1 Prior Investigations & Response Actions Undertaken

Prior investigative work and response actions undertaken at the property by the City and others,

including Phase I ESA activities, completion of a URAM, building demolition, removal of a

20,000-gallon steel No. 4 fuel oil UST, and on-property sampling associated with the former Payne

Property, are described in Section 1.1.2. Recent due diligence environmental investigation

activities conducted on behalf of the City are described in Section 1.1.3.

2.3.2 Extent of Site Chemical Impacts

This section briefly summarizes the horizontal and vertical extent of impacts for COPCs (i.e., lead)

identified during subsurface investigations at the Site. With the exception of recently collected due


diligence investigation-related analytical results, copies of laboratory data reports were included

in prior regulatory submittals. The laboratory analytical report for recently collected soil and

groundwater samples are included as Appendix E.

2.3.2.1 Soil

Prior to the removal of the 20,000-gallon UST and implementation of the recent due diligence

activities, dibenzo(a,h)anthracene (1.4 mg/kg) in soil sample SS-01 collected in 2000 was the only

COPC detected at a slightly elevated concentration. Post-removal soil sidewall and excavation

bottom samples associated with the subsequent removal of the 20,000-gallon UST exhibited

concentrations of C11-C22 aromatic hydrocarbons in excess of RCs for soil; however, following

soil removal activities, a Class A-2 RAO Statement was submitted to MassDEP on behalf of the

City in January 2008 (Tighe & Bond, 2008).

Soil samples collected during the recent due diligence investigation were submitted for laboratory

VOC, EPH, MCP-14 metals and/or PCB analysis (Table 4). VOCs and PCBs were not detected

above laboratory reporting limits in soil samples collected during the due diligence investigation.

Select EPH ranges and pyrogenic and petrogenic PAHs were detected at low concentrations (i.e.,

below MassDEP RCs) in soil samples Elco-SB-8 (0-3’), Elco-SB-9 (0-3’), Elco-SB-9 (8-10’),

Elco-SB-10 (0-3’) as well as the associated duplicate sample, Elco-SS-2 (0-1’), and Elco-SS-3 (0-

1’). In addition, select metals including arsenic, barium, cadmium, chromium, lead, mercury,

nickel, vanadium and/or zinc were detected in each of the soil samples collected in October 2017

at low concentrations (i.e., below MassDEP RCs). Based on the results of the due diligence

investigation, no COPCs were confirmed or identified in soil including soil boring Elco-SB-07

where monitoring well TRC-16 was installed. Detected concentrations of lead in soil boring Elco-

SB-07 ranged from 2.9 mg/kg to 4.8 mg/kg.

2.3.2.2 Groundwater

Current groundwater analytical results from October 2017 are summarized in Table 5. VOCs were

not detected in any of the groundwater samples, including the field duplicate, at concentrations in

excess of laboratory reporting limits. A low (i.e., less than MassDEP RCs) concentration of C19-

C36 aliphatic hydrocarbons (180 micrograms per liter [µg/L]) was detected in monitoring well

TRC-16; however, no additional EPH ranges or PAHs were detected in the groundwater samples

in excess of laboratory reporting limits. Several metals including antimony, arsenic, barium,

beryllium, chromium, lead, mercury, nickel, thallium, vanadium and/or zinc were detected in each

of the groundwater samples; however, with the exception of lead in monitoring well TRC-16, the

detected concentrations of total metals were less than MassDEP RCs.

Total lead was detected in monitoring well TRC-16 at a concentration of 36 µg/L. Noting a stable,

but elevated turbidity reading of 136 NTUs at the time of sample collection, the laboratory was

authorized to analyze the dissolved aliquot for lead. The dissolved concentration of lead in

monitoring well TRC-16 (12 µg/L) was slightly above the RCGW-2 criteria, resulting in the 120-

day reporting condition. The presence of lead in monitoring well TRC-16 represents the only

COPC in groundwater.


2.3.3 Elimination or Control of OHM Sources and Migration

Considering the Site history, including former mill operations, subsequent demolition activities,

results of prior environmental investigations, completed response actions related to a limited UST

release, and the results of recent soil and groundwater due diligence investigation, the presence of

dissolved lead detected in monitoring well TRC-16 appears to be isolated (i.e., not related to any

known or potential release or threat of release as defined by the MCP) and unrelated to any prior

release reported at the Site. Rather, the presence of dissolved lead in TRC-16 (12 µg/L) at a

concentration slightly above the RCGW-2 criteria of 10 µg/L is likely related to the stable, but

elevated turbidity in the monitoring well at the time of sample, the presence of limited shallow

demolition debris observed at the property, or a combination thereof.

Given the physical properties of lead in groundwater, the presence of a relatively low dissolved

concentration of lead (12 µg/L) is unlikely to migrate significant distances. Lead is a naturally-

occurring metal with very low solubility in water, a tendency for bioaccumulation, and little

transport potential in the dissolved phase. Furthermore, elevated concentrations of dissolved lead

have not been detected in wells located downgradient of TRC-16 within the former Payne

Property, or any other on- or off-property monitoring wells, indicating that lead impacts to

groundwater are not present significantly down- or side-gradient to monitoring well TRC-16.

2.4 Elimination of Non Aqueous Phase Liquid (NAPL) Assessment and Control – 310

CMR 40.1056(2)(e)

Not applicable; NAPL has not been observed at the Site.

2.5 Achievement of Level of No Significant Risk – 310 CMR 40.1056(2)(f)

As discussed in detail in Section 3.0, the results of the Method 3 Risk Characterization indicate

that no Imminent Hazard (IH) condition exists at the Site. Cumulative Hazard Indexes (HIs) and

Excess Lifetime Cancer Risks (ELCRs) for the future resident and future construction worker do

not exceed MassDEP Risk Limits. In addition, a qualitative evaluation of the vegetable intake

pathway indicates that best management practices would not be needed should the Site be used for

gardening in the future.

In addition, because Site-specific information indicates that no significant current or future soil

exposure pathways exist at the Site and groundwater data indicate a condition of No Significant

Risk to aquatic receptors based on a comparison of groundwater EPCs to MCP Method 1 GW-3

standards, the Site presents a condition of No Significant Risk to the environment and a Stage II

Environmental Risk Characterization is not required.

2.6 Achievement of Background – 310 CMR 40.1056(2)(g)

A Permanent Solution with No Conditions has been achieved for the Site. Disposal Site-related

impacts are limited to low (i.e., approaching the RCGW-2 criteria of 10 µg/L), localized

concentrations of dissolved lead in shallow groundwater which are related to an unknown source,

likely associated with the presence limited shallow demolition debris observed at the property, and


elevated turbidity at the time of sample collection, that are unlikely to migrate from the property.

A Condition of No Significant Risk has been achieved for the Disposal Site. Therefore, the benefit

of remedial actions would be considered insufficient to justify the cost of those actions and would

be substantial and disproportionate to the net gain in risk reduction, especially in a situation where

No Significant Risk has been achieved.

2.7 Activity and Use Limitations – 310 CMR 40.1056(2)(h)

An AUL is not required to achieve or maintain a Condition of No Significant Risk at the Site.

2.8 Upper Concentration Limits – 310 CMR 40.1056(2)(i)

No EPCs at the Site exceed MCP UCLs.

2.9 Activity and Use Limitation Documentation – 310 CMR 40.1056(2)(j)

Not applicable; an AUL is not required to achieve or maintain a Condition of No Significant Risk

at the Site.

2.10 Data Usability Documentation – 310 CMR 40.1056(2)(k)

A DUA documenting that the data relied upon is scientifically valid and defensible, and of a

sufficient level of precision, accuracy, and completeness to support the PSS, and a Data

Representativeness Evaluation, documenting the adequacy of the spatial and temporal data sets to

support the Permanent Solution with No Conditions are included in Section 4.0.

2.11 Operation, Maintenance, and Monitoring – 310 CMR 40.1056(2)(l)

Operation and maintenance is not necessary to maintain a Condition of No Significant Risk at the

Site.


3.0 METHOD 3 RISK CHARACTERIZATION

This risk characterization has been conducted in a manner consistent with the Massachusetts

Contingency Plan and the requirements of 310 CMR 40.0900, guidelines laid out in MassDEP’s

Guidance for Disposal Site Risk Characterization (MassDEP, 1995 and updates) and MassDEP

petroleum policies (MassDEP, 2002d; MassDEP, 2003). This risk characterization has been

prepared to support the Permanent Solution Statement and is intended to evaluate whether a

condition of No Significant Risk exists for the Site, based on current and future unlimited activities

and uses.

The current vapor intrusion pathway is incomplete because no occupied buildings exist at the Site.

The vapor intrusion pathway is also considered not to be of concern under reasonably anticipated

future conditions, including the construction of an occupied building at the Site, due to the

following:

• NAPL is not present;

• VOCs were non-detect in groundwater samples collected at the Site with reporting limits

significantly less than MCP GW-2 groundwater standards; and

• Although VOCs are detected in soil, impacts are minimal (i.e., infrequently detected at

trace concentrations significantly less than MCP S-1/GW-2 soil standards), indicating that

the VOCs in soil do not represent a significant source of vadose zone impacts.

Therefore, the vapor intrusion pathway is not considered significant currently or in the future, and

has not been further evaluated as part of the risk characterization.

Supporting information applicable to the risk characterization is contained in Appendix F of this

report as follows: Appendix F-1 (Soil Data), Appendix F-2 (Risk and Hazard Calculations for

Soil), Appendix F-3 (Risk and Hazard Calculations for Groundwater), and Appendix F-4 (Trench

Air Modeling and Risk and Hazard Calculations for Trench Air).

3.1 Current and Reasonably Foreseeable Site Activities and Uses

The Site under evaluation in this risk characterization includes an approximately 1.91-acre vacant

parcel of land located in an industrial and residential area of New Bedford, Massachusetts. There

are no occupied buildings located at the Site. The property is bordered to the north by Collette

Street and an active bakery distribution building at 306 Collette Street, to the west across Church

Street by greenhouses, to the south by the former Payne Property, and to the east by residential

properties.

Groundwater at the Site is generally less than 10 feet below ground surface and follows a roughly

southerly flow pattern. The nearest surface water body is the Acushnet River, located

approximately 2,500 feet east of the Site. A wetland is located approximately 750 feet west of the

Site.

No certified vernal pools, ACECs, habitats of species of special concern, or threatened or

endangered species are known to be located within five hundred feet of the Site. The Site is not


located within designated groundwater protection areas, interim wellhead protection areas, the

limits of a productive or potentially productive aquifer, or non-potential drinking water source

areas. There are no documented private drinking water wells located at the Site or in the immediate

vicinity of the Site. The surrounding area is serviced by municipal water. Pursuant to the MCP,

the GW-1 groundwater category does not apply to the area.

Because the property is vacant, current receptors are identified as trespassers and emergency utility

workers, and future receptors, under an unlimited future use scenario, include residents and

construction workers. However, as a short-cut, only future residents and construction workers

have been quantitatively evaluated. If a condition of No Significant Risk is determined to exist for

the future resident scenario and the future long-term construction worker, then other current and

future land uses of lesser frequency and intensity (e.g., the trespasser and emergency utility worker

scenarios) will also be associated with a condition of No Significant Risk.

Construction workers may be exposed to contaminants in soil via incidental ingestion, dermal

contact, inhalation of fugitive dust, and the inhalation of semi-volatile and volatile compounds

released from subsurface soil into trench air. Additional exposure pathways for a construction

worker include dermal contact with exposed groundwater and the inhalation of semi-volatile and

volatile compounds in trench air released from soil. Construction work is assumed to occur at the

location(s) with the highest contaminant concentrations.

Future residential use of the Site is evaluated through child, youth, and adult receptors. Residents

could potentially be exposed to contaminants in soil through dermal contact and incidental

ingestion. Future residents could additionally by exposed via the ingestion of soil contaminants

taken up by homegrown fruits and vegetables. The inhalation of fugitive dusts is considered an

incomplete exposure pathway for future residential use because it is assumed that the Site would

be landscaped, minimizing the generation and release of dust.

3.2 Imminent Hazards

An IH is not presented by the OHM that has come to be located at this Site. This determination is

based on a review of criteria for releases “deemed to pose” an IH under 310 CMR 40.0321(1) and

the criteria for releases that “could pose” an IH under 310 CMR 40.0321(2). The results of this

review are provided in the following sections.

3.2.1 Criteria for Releases Deemed to Pose an Imminent Hazard – 310 CMR 40.0321(1)

The release to the environment is not known to have resulted in the presence of OHM within

buildings, structures, or underground utility conduits at a concentration equal to or greater than 10-

percent of the Lower Explosive Limit (LEL), as set forth in 310 CMR 40.0321(1)(a).

The contaminants detected at the Site either do not possess reactive or explosive characteristics

consistent with 310 CMR 40.0321(1)(b), or the contaminants are not present at concentrations or

in situations expected to threaten human health or safety.


The OHM detected at the Site does not appear to be related to a release to a roadway that could

endanger public safety as set forth in 310 CMR 40.0321(1)(c).

The release would not pose a significant risk to human health if present for even a short period of

time consistent with 310 CMR 40.0321(1)(d) and 310 CMR 40.0950. No concentrations in surface

soil exceed IH reporting thresholds published in 310 CMR 40.0321(2)(b). In addition, drinking

water exposures are not a complete pathway associated with this Disposal Site.

The release did not result in immediate and acute adverse impacts to freshwater or saltwater fish

populations consistent with 310 CMR 40.0321(1)(e). The nearest water body is the Acushnet

River. Because underlying groundwater has not been significantly impacted by the release (i.e.,

mean concentrations in groundwater are below MCP GW-3 standards), there is no immediate

threat to this surface water body.

The release did not result in any apparent effects to human health such as respiratory distress or

dermal irritations as set forth in 310 CMR 40.0321(1)(f). No such effects have been reported to

public health agencies, the property owner, or TRC.

3.2.2 Criteria for Release that Could Pose an Imminent Hazard – 310 CMR 40.0321(2)

There are no reports of the contamination detected at the Site resulting in the measurement of

OHM in a private drinking water supply well at a concentration equal to or greater than ten-times

the GW-1 RC, as set forth in 310 CMR 40.0321(2)(a); the GW-1 reporting category does not apply

to this area. In addition, no private drinking water supply wells are known to be present in the

vicinity of the Site. The Site and surrounding area are supplied potable water by the municipality.

The release did not trigger the IH concentration thresholds established under 310 CMR

40.0321(2)(b). In addition, future residential exposures to soil, as discussed in Section 3.8, do not

exceed the Cumulative Risk Limits set forth in 310 CMR 40.0955(2)(b) and (c).

3.3 Soil and Groundwater Category Classification

3.3.1 Groundwater

As previously described, the Site is not located within a designated Zone II, IWPA, a PPA, or the

Zone A of a Class A Surface Water Body. In addition, the area is serviced by municipal water and

is not indicated to be within 500 feet of any private wells. Therefore, a MCP GW-1 groundwater

category is not considered applicable to this Disposal Site.

Although no currently occupied buildings are present at the Site, buildings may be constructed on

the Site in the future, and average annual depth to groundwater is less than 10 feet below ground

surface. Therefore, the GW-2 groundwater category is considered potentially applicable under

future foreseeable conditions and uses.


Consistent with the requirements of 310 CMR 40.0932(2), where all groundwater is assumed to

eventually discharge to surface waters, the groundwater at the Site is classified into the GW-3

groundwater category.

3.3.2 Soil

The Site is currently vacant. Therefore, children and adults are present at the Site with low

frequency and engage in low intensity activities. Accordingly, the applicable MCP soil category

for current activities and uses is S-2 for accessible soils and S-3 for potentially accessible soils.

Assuming future use of the Disposal Site as a residence, both children and adults are assumed to

be present with high frequency and undergo high intensity exposures. Therefore, the applicable

MCP soil category for anticipated future activities and uses is S-1.

3.4 Hazard Identification

For the Hazard Identification, surface and subsurface soil analytical data collected between June

1987 and October 2017 and groundwater data collected in October 2017 were reviewed to evaluate

the nature and extent of contamination at the Site and to identify contaminants of potential concern

(COPCs). The soil samples were analyzed for VOCs, VPH and EPH fractions, TPH, PCBs, and

metals. Soil analytical data available for quantitative use in the risk characterization are presented

in Appendix F-1.

Data for sampling locations highlighted red in Appendix F-1 were not included in the risk

characterization data set since organic compounds were not detected and metals/PAHs were

present at concentrations less than natural soil background, indicating that these samples were

collected from locations beyond the horizontal and vertical boundary of the Site.

Data from monitoring wells TRC-14 through TRC-17 were considered for evaluation.

Groundwater samples were analyzed for VOCs, EPH fractions, and metals. Groundwater

analytical data available for quantitative use in the risk characterization are presented in Table 5.

Summary statistics for the 0 to 3-foot soil interval, greater than 3-foot soil interval and groundwater

data are presented in Tables 6 through 8, respectively, applicable to the future resident and future

construction worker scenarios.

3.4.1 Hot Spot Evaluation

Soil and groundwater data from the Site were evaluated for the presence of hot spots. A hot spot

is defined in the MCP as a discrete area where the chemical concentrations are substantially higher

than those present in the surrounding area. A discrete area where the average concentration within

the area is greater than ten but less than one hundred times the average concentration in the

immediate surrounding area is a hot spot unless there is no evidence that the discrete area would

be associated with greater exposure potential than the surrounding area. In all cases, a discrete area

where the chemical concentration is greater than one hundred times the concentration in the

surrounding area is to be considered a hot spot. The identification of hot spots is performed to


minimize the likelihood that a location with significantly elevated chemical concentrations will be

diluted by combining it with locations of lesser chemical concentrations in the evaluation.

As further stated in the MCP, in no case should chemical concentrations equal to or less than an

applicable MCP Method 1 standards be considered indicative of a hot spot. Therefore, one

chemical for the 0 to 3-foot soil interval (Table 6 and one chemical for the greater than 3 foot soil

interval (Table 7) were included in the hot spot analysis for soil as all other detected chemicals

were present at levels less than applicable MCP Method 1 soil standards. Groundwater was not

included in the hot spot analysis since maximum detected concentrations were used as EPCs in the

risk characterization.

The following table shows the maximum detected concentration of each of the identified

compounds, the average concentration for each chemical in the applicable soil interval excluding

the maximum detection, and the variance between the maximum concentration and the average

concentration.

Chemical

Maximum

Concentration

(mg/kg)

Average Concentration

Excluding Maximum

(mg/kg)

Variance (Maximum

versus Average

Excluding Maximum)

0 to 3 Foot Soil Interval

Dibenz(a,h)anthracene 1.4 0.093 15-fold

Greater Than 3 Foot Soil Interval

C9-C10 Aromatics 110 3.8 29-fold

As shown above, the maximum detected concentrations of the compounds selected for evaluation

for each soil interval vary from the average soil interval concentrations by less than 100-fold.

Since the areas that contain substances at concentrations greater than ten times the concentrations

of the surrounding areas would not be associated with greater exposure potential, no hot spots as

defined by the MCP were identified for soil.

3.5 Contaminants of Potential Concern

COPCs for the risk characterization may be identified by: a) screening contaminant levels against

available or applicable background values, b) eliminating contaminants with low detection

frequencies and concentrations, and c) eliminating contaminants that are considered laboratory

contaminants and not related to the OHM release. In addition, contaminants that are not reported

above laboratory reporting limits may also be removed from further consideration as COPCs.

MassDEP natural soil background concentrations (MassDEP, 2002b) were used to select COPCs.

Petroleum-related VOCs (e.g., trimethylbenzenes) detected in soil were not evaluated because

VPH analysis captured these compounds as part of the C9-C10 aromatic fraction. Evaluating both

the VPH fractions and specific VOCs included in the fractions would be double-counting the

contribution of these compounds during the risk characterization. In addition, for compounds that

were captured by more than one analytical method (e.g., naphthalene reported in the VOC, VPH


and EPH analyses), the analysis for a sample that resulted in the more conservative data set (i.e.,

the higher concentration) was quantitatively evaluated.

Data summaries for the compounds detected in the 0 to 3-foot and greater than 3 foot soil intervals

are presented in Tables 6 and 7, respectively. On these tables, compounds not selected as COPCs

because their maximum detected concentrations are less than their respective MassDEP natural

soil background concentrations are identified. Detected volatile and semi-volatile subsurface soil

compounds are considered COPCs for the modeling of trench air concentrations (Table 6). All

compounds detected in groundwater are considered COPCs except for mercury which was

detected as a concentration less than its MassDEP background value used in the development of

the MCP numeric standards (see Table 7).

3.6 Dose-Response Assessment

The Dose-Response Assessment is designed to evaluate the potential non-carcinogenic (threshold)

and carcinogenic (non-threshold) effects of COPCs and describes the effects observed in humans

and/or laboratory animals following the intake of a specific dose of the compound. The

information from the Dose-Response Assessment is used in conjunction with information from the

Exposure Assessment (Section 3.7) to estimate the risk and hazard generated by each COPC from

an exposure (Section 3.8).

3.6.1 Non-Carcinogenic Dose-Response Assessment

The toxicity values used in this Dose-Response Assessment of COPCs producing non-

carcinogenic effects are the Reference Doses (RfDs) for oral and dermal exposures and Reference

Concentrations (RfCs) for inhalation exposures. RfD and RfC values provide an estimate of the

daily dose of the COPC to which an individual may be exposed without an appreciable risk of

adverse health effects (including organ damage or reproductive effects) appearing during their

lifetime. RfD and RfC values assume that a threshold dose exists below which there will be

minimal risk for adverse effects to occur.

The chronic RfD and RfC values are based upon a 70-year lifetime exposure, and are approximate

doses derived from an available No Observed Adverse Effect Level (NOAEL) or the Lowest

Observed Adverse Effect Level (LOAEL). Subchronic RfD values are based on defined, less than

lifetime exposures. Subchronic RfDs are appropriate for use in evaluating construction worker-

related risks.

Uncertainty factors (which account for varying sensitivities among populations and extrapolation

of data from animal studies to humans) and modifying factors (which reflect professional judgment

of the toxicity information available) are applied to the NOAEL or LOAEL to determine RfD and

RfC values. These safety factors reflect the quality of the data used and build conservatism into

the Dose-Response Assessment.

COPCs produce non-carcinogenic effects by acting on specific organs (e.g., liver or kidney) within

the body through distinct mechanisms of action. The organ that is affected at the lowest dose (i.e.,

the most sensitive or critical effect) is identified as the target organ. Effects of COPCs acting on


the same target organ and through the same mechanism of action are considered to be additive.

COPCs that produced effects on different target organs or produce effects on the same target organ,

but through different mechanisms of action, are not considered to be additive.

Relative Absorption Factors (RAFs) are used to account for differences between the method of

administration in the study on which the RfD is based and the Site-specific routes of exposure.

These values vary with the medium and route of exposure.

The RfD and RfC values used in this risk characterization are those used by MassDEP in the 2015

Short-forms (MassDEP, 2015). Chronic and subchronic RfDs and RfCs and medium-specific

RAFs are listed in the Risk Calculation Spreadsheets in Appendices F-2 through F-4.

3.6.2 Carcinogenic Dose-Response Assessment

The U.S. EPA has developed a system for classifying chemicals according to the likelihood that

the compound is a human carcinogen. This system groups chemicals into five classes based upon

the weight-of-evidence (of carcinogenicity) of the available data. Consistent with MassDEP risk

characterization guidelines, class A, B, and C carcinogens are evaluated in a Method 3 risk

characterization. The oral slope factors (SFs) and inhalation unit risks (URs) used in this risk

characterization are those used by MassDEP in the 2015 Short-forms (MassDEP, 2015).

Carcinogenic toxicity values (SFs and URs) are presented in the Risk Calculation Spreadsheets in

Appendices F-2 through F-4.

3.7 Exposure Assessment

Consistent with the requirements of 310 CMR 40.0923, the Exposure Assessment requires the

identification of all current and reasonable foreseeable activities and uses associated with a site

and a description of how these uses and activities could result in the exposure of human receptors

to the COPCs present. Receptors and exposure pathways applicable to this risk characterization

are discussed in Section 3.1. The following sections discuss the exposure assumptions used for

each receptor, developed to estimate the frequency and intensity of the exposure, and the medium-

specific exposure point concentrations, used to describe the environmental concentrations to which

specific receptors may be exposed.

Future receptors include residents and construction workers. These receptors are used to

conservatively represent current trespassers and emergency utility workers. Because MassDEP

Short-forms have been used for the residential and construction worker soil scenarios, standard

default exposure assumptions provided by MassDEP have been used for these scenarios. If a

condition of No Significant Risk is determined to exist for these future scenario, then other current

and future land uses of lesser frequency and intensity will also be associated with a condition of

No Significant Risk.

3.7.1 Exposure Assumptions

Exposure assumption values listed represent either best professional judgment based on site-

specific information or values considered consistent with or those listed in MassDEP’s Guidance


For Disposal Site Risk Characterization (July 1995), presented by MassDEP in published Short-

forms, or used by MassDEP in the development of the MCP numerical standards (June 2014).

Construction Worker: Exposures to COPCs could occur during subsurface excavations that

expose contaminated soil and groundwater. Potential exposures to soil COPCs are assumed to

occur 8 hours/day for 130 days/year for construction workers. The exposure duration for non-

cancer endpoints was averaged over 0.5 years (182 days). Workers are identified as adults (58 kg

average body weight) involved in physical activities equivalent to an average inhalation rate of 20

cubic meters per day (m3/day). Inhalation of fugitive dusts outdoors by adult workers was

evaluated using a PM10 of 60 micrograms per cubic meter (µg/m3). The incidental ingestion rate

of soil was set at 100 mg/day. Dermal contact with soil COPCs was assumed via the face, hands,

forearms, and feet (3,477 square centimeters [cm2]) using a soil adherence factor of 0.29 mg/cm2.

Worker exposures to trench air COPCs released from soil are assumed to occur 8 hours/day, 130

days/year for 0.5 years, consistent with the soil exposure evaluation for the construction worker.

Assumptions used in the modeling of COPCs from soil to trench air are included in Appendix F-

4, Table 1.

Resident: For the adult, youth, and child resident, outdoor exposures to COPCs in soil are

assumed to occur for 150 days/year (5 days/week for 30 weeks/year). The exposure duration for

non-cancer endpoints of toxicity was averaged over 16 years for the adult, and 7 years each for the

youth and child. The average weights of the adult, youth, and child were set at 58.7 kg, 39.9 kg,

and 17.0 kg, respectively. Incidental ingestion of soil was set at 50 mg/day and 100 mg/day for

the adult/youth and child, respectively. Dermal contact with COPCs in soil was evaluated using a

soil adherence factor of 0.13 mg/cm2 for the adult,0.14 mg/cm2 for the youth, and 0.35 mg/cm2 for

the child which assumes exposure via the face, hands, forearms, lower legs, and feet (5653 cm2,

4427 cm2, and 2431 cm2 for the adult, youth, and child, respectively). The MassDEP Resident

Soil Short-form was used to provide a quantitative evaluation of the vegetable intake pathway, if

applicable.

3.7.2 Exposure Point Concentrations

EPCs represent the COPC concentrations in a medium that a receptor may come in contact with at

the exposure point. Depending on the exposure scenario, the exposure point may consist of an

area or zone of potential exposure, or a single exposure point. EPCs for this risk characterization

were derived from the analytical surface and subsurface soil and groundwater data tabulated in

Tables 1 through 3, respectively, and based on soil to air fate and transport modeling results

presented in Appendix F-4 (Table 1) for trench air.

For exposures to COPCs in soil, the arithmetic mean concentration has been used for most COPCs.

However, for any COPC with an arithmetic mean concentration that exceeds its maximum detected

concentration, the maximum detected concentration was used as the EPC. Tables 4 and 5 indicate

whether the soil EPC is based on a maximum detected concentration or an arithmetic mean

concentration.

For exposures to groundwater, maximum detected concentrations have been used as EPCs. In

addition, maximum detected subsurface soil concentrations for volatile and semi-volatile


compounds were used to model trench air concentrations for the construction worker scenario. For

the soil to trench air scenario, modeling algorithms and assumptions are provided in Appendix F-

4, Table 1. For the soil to trench air pathway, the Johnson & Ettinger model was used to estimate

soil gas concentrations (based on maximum detected VOC soil concentrations), which were then

diluted into a trench using conservative algorithms and assumptions.

3.7.3 Estimation of Chemical Intake

To evaluate the risk of harm to human health, the intake of each COPC must be estimated, a process

which involves assessing the amount of material in contact with the receptor and the amount

actually available for absorption by the body. This assessment is achieved through the calculation

of an average daily dose (ADD) for each COPC and for each route of exposure. Compound-

specific and exposure route-specific Relative Absorption Factors (RAFs) are used in the ADD

equations to convert an exposure (amount) to a dose (amount per unit body weight).

The general ADD equation is as follows and is consistent with that provided in MADEP’s

Guidance for Disposal Site Risk Characterization (July, 1995):

ADD = Total Amount of Chemical Taken In

(Body Weight) * (Averaging Period)

The specific ADD equations for the various exposure pathways evaluated are provided below:

Incidental Ingestion of Soil

ADD = (EPC)*(Ingestion Rate)*(Exposure Frequency)*(Exposure Period)*RAF

(Body Weight)*(Averaging Period)

Dermal Contact with Soil

ADD = (EPC)*(Surface Area)*(Exposure Frequency)*(Exposure Period)*(Adherence Factor)*RAF


Dermal Contact with Groundwater

ADD = (EPC)*(Surface Area)*(Exposure Frequency)*(Exposure Duration)*(Exposure Period)*RAF*Kp


Inhalation of Trench Air

ADD = (EPC)*(Exposure Time)*(Exposure Frequency)*(Exposure Duration)

(Averaging Period)

For the fugitive dust pathway, equations presented in Characterization of risks due to inhalation

of particulates by construction workers (Revised Technical Update; 2008) were used. The

equations used are as follows:

Inhalation of Fugitive Dust – GI System


ADD = (EPC)*1.5*(Inhalation Rate)*RAF*(Exposure Duration)*(Exposure Frequency)*(Exposure Period)*PM10


Inhalation of Fugitive Dust – Respiratory System

ADD = (EPC)*0.5*(Inhalation Rate)*RAF*(Exposure Duration)*(Exposure Frequency)*(Exposure Period)*PM10


The averaging period (AP), or period of time over which the total intake of contaminant is

averaged, can be adjusted to calculate the ADD for an acute exposure (AP = 1 day or less), for a

subchronic exposure (AP = few days to several months), and for a chronic exposure (AP = several

months to 70 years).

Exposure assumptions and the specific equations used to calculate ADDs are provided in the risk

calculation spreadsheets provided in Appendices F-2 through F-4. The ADD values calculated for

chronic/subchronic exposures were compared to the toxicity values (e.g., RfDs, RfCs, and SFs)

discussed in Section 3.6. This comparison provides a numerical estimate of the levels of risk and

the potential for adverse health effects to occur due to exposure to COPCs, as described in the next

section.

3.8 Risk Characterization

To characterize the risk of harm to human health from potential exposures to COPCs identified at

the Site, carcinogenic and non-carcinogenic risks were characterized for each COPC and receptor,

and the cumulative receptor risk values were compared to the MassDEP Risk Limits to assess the

condition of No Significant Risk. In addition, the condition of No Significant Risk was evaluated

through comparison of EPCs for the COPCs to Applicable, Available or Suitably Analogous

Public Health Standards.

To estimate non-carcinogenic risk, the Hazard Quotient for each COPC was calculated by dividing

the ADD computed in the Exposure Assessment (Section 3.7) by the RfD or RfC identified in the

Dose-Response Assessment (Section 3.6). The cumulative Hazard Index (HI) for each receptor

was subsequently calculated by summing the COPC hazard quotients for the exposure pathways

applicable to each receptor. This HI is called a Screening HI and provides a conservative estimate

of the true hazard because it assumes additivity even though COPCs may exert effects on different

organ systems and/or through different mechanism of action. The Screening HI was first compared

to the Cumulative Receptor Non-Carcinogenic Risk Limit (Cumulative Receptor Hazard Index)

of 1 (310 CMR 40.0993(6)) to characterize the risk of harm to human health, and to establish

whether a condition of No Significant Risk exists at the Site. If the Screening HI was less than 1,

no further discussion was necessary to characterize noncancer hazard. However, if the Screening

HI exceeded the Risk Limit of 1, the Screening HI was segregated by target organ, as described in

MassDEP guidance (MassDEP, 1995). Each target organ HI was then compared to the Risk Limit

of 1 to establish whether a condition of No Significant Risk exists at the Site.

To calculate the Excess Lifetime Cancer Risk (ELCR) for each COPC, the Lifetime Average Daily

Dose (LADD) estimated in the Exposure Assessment is multiplied by the SF or UR identified in


the Dose-Response Assessment. The ELCR for each COPC is then summed to calculate the Total

ELCR for each exposure pathway. The Total Site Cancer Risk for each receptor is subsequently

computed by summing the Total ELCR values for the exposure pathways applicable to each

receptor. The Total Site Cancer Risk is then compared to the Total Site Cancer Risk Limit of 1E-

05 (CMR 40.0993(6)) to characterize the risk of harm to human health, and to establish whether a

condition of No Significant Risk exists at the Site, as defined in 310 CMR 40.0993(7).

The following provides a discussion of the receptor-specific risks and hazards evaluated in the risk

characterization. Table 9 presents a summary of the receptor-specific total risks and hazards.

Individual COPC, pathway and route-specific HQs and ELCRs are shown in Appendices F-2

through F-4.

Cumulative HIs and ELCRs for the future resident and future construction worker do not exceed

MassDEP Risk Limits. A quantitative evaluation of the vegetable intake pathway was not

performed because the only COPCs with the potential to bioaccumulate into plant tissue are lead

and zinc. Lead and zinc were detected in soil at maximum concentrations (150 mg/kg and 490

mg/kg, respectively) that are less than their MCP S-1 soil standards (200 mg/kg and 1,000 mg/kg,

respectively). This comparison indicates that best management practices would not be needed

should the Site be used for gardening in the future.

3.8.1 Applicable or Suitably Analogous Public Health Standards

As part of the evaluation of the condition of No Significant Risk of harm to human health (as

defined in 310 CMR 40.0993(7)), the MCP requires a comparison of COPC EPCs to Applicable

or Suitably Analogous Public Health Standards (310 CMR 40.0993(3)). Such standards include,

but are not limited to, Massachusetts Air Quality Standards promulgated in 310 CMR 6.00,

Massachusetts Surface Water Quality Standards promulgated in 314 CMR 4.00, and

Massachusetts Drinking Water Quality Standards promulgated in 310 CMR 22.00.

As noted in Section 3.1, groundwater beneath the Site is not classified into the GW-1 groundwater

category. Therefore, comparison of COPC groundwater concentrations to MassDEP Drinking

Water Standards is not required for the evaluation of Significant Risk of harm to human health. In

addition, air and surface water quality standards are not considered applicable to the Disposal Site.

3.9 Uncertainty Analysis

Risk characterizations are subject to a number of uncertainties. As a result, risk estimates derived

from the equations and assumptions in this risk characterization should not be interpreted as

absolute estimates of the risks of harm to human health posed by potential exposures to COPCs

reported at the Site.

General sources of uncertainty include:

• adequacy of the characterization;

• adequacy of the sampling plan;

• quality and treatment of the analytical data;


• accuracy of the exposure assumptions; and

• development of toxicity values (RfDs, RfCs, SFs, and URs).

Site-specific uncertainties are discussed below. As discussed below, conservative assumptions are

selected for use in the risk characterization process which generally leads to overestimation, rather

than underestimation, of risks and hazards.

3.9.1 Hazard Identification

Sampling was conducted with bias, targeting areas that were likely to have elevated concentrations

of contaminants based on field observations and PID screening. This type of sampling strategy is

commonly used for site characterization. However, it should be noted that the soil data set is likely

to over-represent the concentrations of COPCs present across the Site, resulting in an

overestimation of the risks and hazards at the Site.

3.9.2 Dose-Response Assessment

In the Dose-Response Assessment, Uncertainty and Modifying Factors, applied to toxicity

information to obtain RfD and RfC values, are used to account for the following uncertainties,

which, in turn, can add to the overall uncertainty of the risk characterization findings:

• the use of dose-response information from effects observed at high doses to predict the

adverse health effects that may occur following exposure to the low levels expected from

human contact with the COPCs in the environment;

• the use of dose-response information from short-term exposure studies to predict the

effects of long-term exposures, and vice-versa;

• the use of dose-response information from animal studies to predict adverse health effects

in humans; and

• the use of dose-response information from homogeneous animal populations or healthy

human populations to predict the adverse health effects likely to be observed in the

general population, consisting of individuals with a wide range of sensitivities.

In addition, the following practices result in additional uncertainties in the dose-response

assessment:

• the use of oral toxicity values as surrogate toxicity values for the dermal route of

exposure; and

• the use of surrogate toxicity values for compounds without assigned values, such as those

used to characterize the petroleum hydrocarbon fractions.


3.9.3 Exposure Assessment

The Exposure Assessment focuses on the evaluation of non-carcinogenic and carcinogenic effects

for an individual who is exposed to the COPCs. Conservative exposure assumptions, as

recommended by MassDEP, were used for intake rates, surface areas, and body weights. Exposure

frequencies and exposure periods were default MassDEP values. In addition, conservative

MassDEP default assumptions and maximum detected groundwater and soil concentrations were

used to estimate direct contact groundwater risks and in the modeling of soil to trench air

concentrations. The use of conservative EPCs, exposure assumptions and model inputs can

potentially overestimate the risk of harm from exposure to the COPCs and contribute to the

uncertainty of the risk characterization.

3.10 Public Welfare Risk Characterization

Per the MCP (310 CMR 40.0994), there are two purposes for characterizing the risk to public

welfare: 1) to identify and evaluate nuisance conditions, which may be localized, and 2) to identify

and evaluate significant community effects.

The characterization of risk to public welfare considers effects that are or may result from the

presence of residual impacts. Further, the characterization of risk to public welfare is for current

and reasonably foreseeable activities and uses, requiring an understanding of the Site, the receptors

and exposure information. Per 310 CMR 40.0994, the characterization of risk to public welfare

does not consider pecuniary effects or private resources.

The risk characterization has shown that the Site, as it currently exists, poses No Significant Risk

to health. Benefits to the public, and the good of the general population, are not affected by the

Site (i.e., a public resource is not impacted, such as a community water supply, nor is the local

atmosphere impacted by noxious odors).

Factors that the MCP takes into consideration to evaluate nuisance conditions and significant

community effects include the following:

▪ Nuisance conditions – The breathing zone of ambient and/or indoor air at the Site is free

of persistent, noxious odors (at present and for the reasonably foreseeable future). There

are also no impacts from the Site on drinking water (noxious taste/odors), and there are no

livestock impacts. Per the MCP, a nuisance condition is not present.

▪ Loss of active or passive property uses – Not applicable, the Site is currently vacant. It

is expected that Site will return to active use as commercial land.

▪ Non-pecuniary effects – No public resources are known to be impacted by the Site. No

public water supplies are impacted (odors, etc.), and the atmosphere is not impacted by

noxious odors.

▪ Upper Concentration Limits – Soil and groundwater EPCs are less than applicable MCP

UCLs (see Tables 6 through 8).


Based on the above information a condition of No Significant Risk to public welfare exists at the

Disposal Site.

3.11 Characterization of Risk to Safety

Risk of harm to Safety associated with the release of COPCs at the Site was evaluated in

accordance with the requirements of 310 CMR 40.0941(2) and 40.960, and was based on visits

and on observations made consistent with MCP Response Action Performance Standards (RAPS)

as defined in 310 CMR 40.0191. COPC-related safety hazards evaluated under current and future

foreseeable site conditions included: the presence of open pits; lagoons; uncontained corrosive,

flammable/ignitable, reactive, or infectious materials; threat of fire or explosion (including the

presence of explosive vapors); weakened berms; and rusted or corroded drums or containers.

Qualitative observations did not reveal hazards associated with the COPC release likely to pose a

threat of physical harm or bodily injury to people, and consequently, a condition of No Significant

Risk of harm to safety is considered to exist at the Site. Evaluation of risk of harm to safety through

comparison of conditions to applicable or suitably analogous safety standards (e.g., Lower

Explosive Limits) was not considered applicable to this Site.

3.12 Stage I Environmental Risk Characterization

This Stage I - Environmental Risk Characterization (ERC) briefly describes the habitat types and

biota potentially present at the Site and evaluates the potential risks to biota associated with

exposure to on-site contaminants. This ERC was conducted under the MCP in accordance with:

“Guidance for Disposal Site Risk Characterization, Method 3 – Environmental

Risk Characterization. Massachusetts Department of Environmental Protection,

Interim Final Policy WSC/ORS-95-141, April 1996”.

The objective of this Stage I ERC is to determine whether (1) a state of “no significant risk of

harm…to the environment” exists at the site and further action is not warranted, or (2) remediation

or additional site investigation is needed to more accurately characterize risks to biota at this site.

3.12.1 Site Description

The Site under evaluation in this risk characterization includes an approximately 1.91-acre vacant

parcel of land located in an industrial and residential area of New Bedford, Massachusetts. There

are no occupied buildings located at the Site. The property is bordered to the north by Collette

Street and an active bakery distribution building at 306 Collette Street, to the west across Church

Street by greenhouses, to the south by the Payne Cutlery Disposal Site, and to the east by

residential properties.

Groundwater at the Site is generally less than 10 feet below ground surface and follows a roughly

southerly flow pattern. The nearest surface water body is the Acushnet River, located

approximately 2,700 feet east of the Disposal Site. A wetland is located approximately 750 feet

west of the Disposal Site.


3.12.2 Ecological Characterization

The following sections discuss habitat characteristics present at the Site and the vicinity and

identify potential ecological receptors.

3.12.2.1 Habitat Characterization

Based on a review of the Massachusetts online Geographical Information System (GIS) database,

estimated or priority habitats of state-listed threatened, endangered or species of special concern

are not present at the Site or in the vicinity. In addition, certified or potential vernal pools or ACEC

are also not located within 1,000 feet of the Site.

The 1.91-acre Site is located within an urbanized setting that provides limited terrestrial habitat

for ecological receptors. Although currently undeveloped, the vacant lot consists of early

successional vegetation with no forested areas present at the Site. The Acushnet River is located

approximately 0.5 mile east of the Disposal Site and represents the closest body of water to the

Site. The portion of the Acushnet River in the vicinity of the Site is classified by MassDEP as a

Class SB surface water body, meaning it is a habitat for fish, other aquatic life and wildlife,

including for their reproduction, migration, growth and other critical functions, and for primary

and secondary contact recreation. However, combined sewer overflows impact this reach of the

Acushnet River.

3.12.2.2 Ecological Receptors

There is limited potential for terrestrial environmental receptors (other than typical suburban fauna

such as ground-foraging birds or rodents) to be present at the Site due to the highly developed

character of the Site location and the absence of any significant habitat containing diverse

vegetation. However, a variety of ecological receptors are likely to use the aquatic habitat

associated with the downgradient Acushnet River. A diverse assembly of fish and aquatic

invertebrates including shellfish are likely present within the Acushnet River. These organisms

would be preyed upon by higher trophic levels species such as fish and birds such as wading birds

(e.g., herons). In addition, mammals such as raccoons are likely to forage along suitable habitats

present adjacent to the Acushnet River.

3.12.3 Exposure Pathways

Potential pathways in which ecological receptors may be exposed to site contaminants were

evaluated to determine if the identified pathways are complete or incomplete and as such, do not

require further investigation. Contaminants present within surface soils may potentially adversely

affect terrestrial ecological receptors, while surface soils or groundwater may be transported to the

aquatic habitat via surface water runoff or groundwater discharge. These exposure pathways were

assessed as follows:

Surface Soil to Terrestrial Receptors: Contaminants present within surface soils at the Site may

potentially be bioaccumulated by vegetation and/or soil invertebrates such as earthworms that are


then ingested by organisms in higher trophic levels (e.g. birds). In addition to this indirect

exposure pathway, terrestrial receptors may be directly exposed to soil contaminants (dermal and

inhalation exposure) through burrowing activities or the inadvertent ingestion of soil as they groom

and forage on plants or soil invertebrates (which are dependent on the presence of vegetation that

provides the basis for the food chain). However, as the Disposal Site is less than two acres in size,

significant terrestrial ecological receptors are not present. Therefore, this pathway is considered

incomplete and is not being considered further.

Groundwater to Aquatic Receptors: A variety of contaminants of concern (metals) were

detected within groundwater at the monitoring wells sampled in October 2017. These

contaminants may potentially discharge to the downgradient Acushnet River or other surface water

bodies/wetlands. Therefore, this exposure pathway is considered complete and is evaluated further

in this Stage I ERC by conducting an effects-based screening evaluation to determine whether

exposure to contamination resulting from the discharge of groundwater to the Acushnet River or

other aquatic habitats is likely to be significant and warrant a more comprehensive Stage II

Ecological Risk Characterization.

Surface Soil to Aquatic Receptors (Surface Water/Sediment): The erosion and subsequent

transport of contaminated surface soils at the Site may potentially affect ecological receptors

inhabiting nearby surface waters and/or sediments. However, based on the absence of potential

erosion pathways from the Site to aquatic habitats, this pathway is considered incomplete and is

not evaluated further.

3.12.4 Environmental Analytical Data

Monitoring data collected in October 2017 from four groundwater monitoring wells were

quantitatively evaluated, as most representative of current conditions. The four groundwater

samples were analyzed for VOCs, EPH and total metals, however, only 11 inorganics were

detected in the samples. The concentration data are presented in Table 5. Groundwater summary

statistics are presented in Table 8.

3.12.5 Risk Characterization of Significant Exposure Pathways

The primary ecological exposure pathway at the Site would involve the potential for contaminated

groundwater to be discharged to the Acushnet River or other aquatic habitats resulting in direct

contact by aquatic and/or benthic receptors. Direct exposure of Acushnet River receptors

including invertebrates and fish to excessive levels of contaminants in groundwater could result in

acute or chronic toxicity.

An effects-based screening assessment, that compares observed contaminant concentrations in

groundwater with published surface water effects based screening benchmark values, was

conducted for this pathway. Toxicological benchmarks for screening COPCs that may potentially

affect aquatic biota were derived from threshold values used by MassDEP. Specifically, GW-3

standards were first compared to the maximum detected concentrations detected in Site

groundwater samples in order to select COPCs. GW-3 standards are generally applicable for

evaluating risks to ecological receptors since they account for dilution and attenuation of


groundwater contaminants prior to discharging to downgradient aquatic habitats. This comparison

is presented in Table 5 with the results of this comparison discussed below.

A total of 11 inorganics were detected in one or more of the four groundwater samples. The GW-

3 standards for 10 of these 11 inorganics were not exceeded by the maximum detected

concentrations of antimony, arsenic, barium, beryllium, chromium, mercury, nickel, thallium,

vanadium and zinc. Therefore, these constituents were not retained as COPCs and are not

evaluated further. However, the maximum detected concentration of lead (36 ug/L) exceeds its

GW-3 standard of 10 ug/L and was retained as a COPC.

Environmental receptors present at the Acushnet River would not be directly exposed to

groundwater present at individual monitoring wells but are exposed to groundwater from a

disposal site as it discharges to nearby surface water bodies. As stated in Section 40.0995(a) of

the MCP regulations, a Method 3 characterization of risk to the environment shall be based on

information identified in 310 CMR Section 40.0901 through 40.0920. Section 40.0920 states that

the identification of Exposure Point Concentrations shall provide an estimate of exposure which a

receptor may receive over a period of time. Over a period of time would be indicative of chronic

or subchronic exposure.

Section 40.0926((3)(b) of the MCP regulations states that for chronic and subchronic exposures

the arithmetic average of site data is acceptable as an EPC provided that: 1) the arithmetic average

is less than or equal to the applicable standard or risk-based concentration limit (this condition is

met as the average lead groundwater concentration of 9.55 ug/L is less than the GW-3 standard of

10 ug/L), 2) 75% of the data points used in the averaging procedure are equal to or less than the

applicable standard (this condition is met for lead as the GW-3 standard was exceeded in only 1

of 4 groundwater samples), and, 3) no data point used in the averaging is greater than 10 times the

applicable standard (this condition is met as the maximum concentrations of lead is less than 4.0

times the standard). Based on this analysis, the mean concentration for lead is acceptable as an

EPC.

The mean concentration of lead was calculated using the total lead concentrations for monitoring

wells TRC-14, TRC-15, TRC-16 and TRC-17 as presented in Table 5. One-half the reporting limit

was used in the calculation for monitoring wells exhibited “non-detect” values (i.e., TRC-14 and

TRC-17) for total lead (Table 8). As the mean concentration of the groundwater COPC lead (total;

9.55 µg/L) is less than its applicable GW-3 standard (10 µg/L), risks to ecological receptors

inhabiting the Acushnet River or other downgradient aquatic habitats are not anticipated from this

COPC.

Therefore, a condition of No Significant Risk to the environment is present for the Site and no

additional environmental risk characterization is warranted.


3.13 Conclusions and Recommendations

Human Health Risk Characterization

No IH condition exists at the Site. Cumulative HIs and ELCRs for the future resident and future

construction worker do not exceed MassDEP Risk Limits. In addition, a qualitative evaluation of

the vegetable intake pathway indicates that best management practices would not be needed should

the Site be used for gardening in the future.

3.13.1 Public Welfare

Soil and groundwater UCLs are not exceeded and no community in the vicinity of the Site

experiences specific adverse impacts to public welfare. Therefore, a condition of No Significant

Risk of harm to Public Welfare exists at the Site.

3.13.2 Safety

Qualitative observations did not reveal hazards associated with the COPC release likely to pose a

threat of physical harm or bodily injury to people, and consequently, a condition of No Significant

Risk of harm to Safety exists at the Site. Evaluation of risk of harm to safety through comparison

of Site conditions to applicable or suitably analogous safety standards (e.g., LELs) was not

considered applicable to this Site.

Environmental Risk Characterization

Because Site-specific information indicates that no significant current or future soil exposure

pathways exist at the Site and groundwater data indicate a condition of No Significant Risk to

aquatic receptors based on a comparison of groundwater EPCs to MCP Method 1 GW-3 standards,

the Site presents a condition of No Significant Risk to the environment and a Stage II



4.0 DATA USABILITY AND REPRESENTATIVENESS

4.1 Data Usability Assessment

4.1.1 Analytical Data Usability Assessment

Refer to Appendix D for a summary of the DUA associated with the City’s investigation of the

Site. In general, the analytical data are usable for MCP decisions and a Representativeness

Evaluation based on the CAM requirements for acceptable accuracy, precision, and sensitivity. In

general, the data are valid as reported and may be used for decision-making purposes with no

cautions and/or limitations.

4.1.1.1 Rejection of Analytical Data

Appendix II of the MCP Representativeness Evaluations and DUA Guidance document

(MassDEP, 2007) was used to evaluate if gross failures of quality control existed in the TRC data

set. Any gross failures of quality control in the sampling or analytical procedures are noted in the

DUA located in Appendix D.

4.1.2 Field Quality Control Data Usability Assessment

Quality control (QC) in the field was assessed in the DUA provided in Appendix D. In general,

the results of these QC samples were within the established acceptance criteria. Any non-

conformances are noted in Appendix D.

Holding times were achieved for all analyses performed. Sampling procedures and sample

preservation techniques were conducted in accordance with TRC Standard Operating Procedures

(SOPs).

In general, the data are usable for MCP decisions and a Representativeness Evaluation due to

acceptable accuracy, precision, and sensitivity on the basis of the field quality control component

of the program.

4.1.3 Achievement of Data Quality Objectives

Data Quality Objectives (DQO) for the Site program were as follows:

▪ To assess the nature and extent of OHM present in soil and groundwater at the property.

▪ To evaluate the potential risks posed by chemicals to human health, safety, public welfare

and the environment.

▪ To evaluate the achievement of a Condition of No Significant Risk as defined by the MCP.

The DUA evaluated whether the data were usable to achieve project objectives. In addition, any

cautions or limitations on the data which could affect the achievement of these objectives or the

decision-making process were also highlighted.


4.2 Representativeness Evaluation

TRC prepared this Representativeness Evaluation to describe the extent to which Site data provide

an accurate representation of Site environmental characteristics pursuant to 310 CMR

40.1056(2)(k) of the MCP and the MCP Representativeness Evaluations and Data Usability

Assessments Guidance document issued by MassDEP in September 2007 (Policy #WSC-07-350;

MassDEP, 2007). The precision, accuracy and sensitivity of the Site data used in this

Representativeness Evaluation were discussed in the DUA section (Section 4.1) of this PSS. As

stated in the DUA, the data are valid as reported and may be used for decision-making purposes

with cautions and/or limitations noted in Appendix D.

4.2.1 Conceptual Site Model

A detailed discussion of the CSM, including the Disposal Site history, COPCs, Site-specific

historic documentation, investigation and remediation activities and data evaluation is provided in

Section 2.2.

4.2.2 Work Plan, Data Quality Objectives and Data Collection Approach

A summary of Site investigation activities and remediation activities performed by the City and

others are found in Sections 1.1.2 and 1.1.3.

The DQOs for the City’s Site testing programs were to collect data that could be used to assess the

nature and extent of OHM present in soil and groundwater; evaluate the potential risks posed by

soils and groundwater to human health, safety, public welfare and the environment; and support

Site closure, if appropriate. The results of the sampling work performed are summarized in Table

4 and Table 5.

4.2.3 Use of Field/Screening Data

During the field investigations, TRC used field screening data to aid in the collection of soil

samples for laboratory analyses. Field screening for soil samples included use of a PID and the

MassDEP Jar Headspace Analytical Screening Procedure to evaluate relative levels of VOCs at

various depths at each soil boring location. PID readings were recorded on the field boring logs,

which are included in Appendix C. No significant PID readings above background were

encountered during the field investigations.

4.2.4 Selection of Sampling Locations and Depths

Summaries of the sampling locations, depths, chemical analyses and rationale for the investigative

samples collected at the Site are provided in Section 1.0 (Introduction) and Section 2.0 (Permanent

Solution with No Conditions Supporting Documentation). A summary of the soil and groundwater

analytical results are provided in Table 4 and Table 5.


4.2.5 Number and Spatial Distribution of Sampling Locations

Summaries of Site investigation and remediation activities performed by the City and others are

found in Section 1.1.2 and 1.1.3.

The soil samples collected to evaluate potential soil impacts at the Site are summarized in Table

1. On behalf of the City, ten (10) soil borings were advanced within the footprint of the property

and three (3) surface soil samples were collected during TRC’s due diligence investigation

activities. In association with TRC’s environmental investigation activities, a total of twenty-four

(24) soil samples, including duplicates, underwent laboratory analysis of VOCs, EPH, PCBs

and/or metals. TRC’s sampling supplemented previous investigation activities which included the

installation of eleven (11) soil borings and a total of seventeen (17) soil samples, including

duplicates, collected and submitted for analysis of VOCs, VPH, EPH, TPH, PCBs and/or metals

(total and TCLP). The soil analytical results for all samples were utilized to evaluate the nature

and extent of potential soil impacts at the Site. The number and spatial distribution of samples at

the Site is sufficiently representative of Site conditions.

4.2.6 Temporal Distribution of Samples

The conditions at this Site do not warrant monitoring over time. No time critical conditions were

identified at the Site.

4.2.7 Critical Samples

Critical soil samples are identified as those samples used in the calculation of EPCs for the Method

3 Risk Characterization presented in Section 3.0, which include soil and groundwater samples

collected by TRC and others. The sample results for these critical samples are provided in

Appendix F-1.

4.2.8 Completeness

Although certain historic VOC results were not usable for project objectives, as identified in

Appendix D, there was sufficient Site data to adequately quantify EPCs as a result of the DUA

presented in Appendix D. Therefore, >90% completeness was achieved for Site data.

4.2.9 Uncertainty and Inconsistency

There are no known uncertainties and inconsistencies.

4.2.10 Conclusion from Representativeness Evaluation

TRC has developed the following conclusions with respect to the representativeness of the Site

data to actual Site conditions:


▪ As indicated by the DUA presented in Appendix D, the Site data used in this PSS to

demonstrate that a Condition of No Significant Risk has been achieved are consistent

and/or comparable to current MassDEP CAM requirements.

▪ The number of samples, sample depths, spatial and temporal distribution of the samples is

sufficient to identify releases from the suspected source areas and to delineate the extent of

OHM impacts at the Site.

▪ No significant discrepancies between Site history information, field screening results,

and/or laboratory sample results were identified that would undermine the conclusions of

this PSS.

Based on the above conclusions, TRC has determined that the Site data are sufficiently

representative of actual Site conditions and may be used to support this PSS.


5.0 PERMANENT SOLUTION WITH NO CONDITIONS

A Permanent Solution with No Conditions has been achieved at the Site, based on, and in

accordance with, the following (310 CMR 40.1040 & 40.1041(1)):

▪ Response actions have been conducted to achieve a level of No Significant Risk;

▪ The source of OHM at the Site has been controlled or eliminated;

▪ Plumes of dissolved-phase OHM in groundwater or vadose zone soil vapors, and NAPL,

are not present at the Site;

▪ No threats of release have been identified at the Site;

▪ An AUL is not required to achieve or maintain a level of No Significant Risk; and

▪ Site soil and groundwater EPCs based on groundwater monitoring conducted at the subject

property, do not exceed an MCP UCL.

A Method 3 Risk Characterization was used to characterize human health risk at the Site. No IH

condition exists at the Site. Cumulative HIs and ELCRs for the future resident and future

construction worker do not exceed MassDEP Risk Limits, indicating a Condition of No Significant

Risk for soil and groundwater under current and potential future Site activities and uses.

Because Site-specific information indicates that no significant current or future soil exposure

pathways exist at the Site and groundwater data indicate a condition of No Significant Risk to

aquatic receptors based on a comparison of groundwater EPCs to MCP Method 1 GW-3 standards,

the Site presents a condition of No Significant Risk to the environment and a Stage II


No other response actions are necessary at the Site.


6.0 PUBLIC INVOLVEMENT

The public involvement and/or notification activities required under 310 CMR 40.1403(3)(f)

include notification regarding the availability of the PSS Statement filed for this Site, which must

be submitted to the Chief Municipal Officer and Board of Health in the City of New Bedford. The

notifications will be made in writing concurrently with the filing of the PSS.

Copies of the public notification letters are provided in Appendix G.

1. TRC Environmental Corporation’s (TRC’s) study was performed in accordance with generally

accepted practices of other consultants undertaking similar studies at the same time and in the

same geographical area, and TRC observed that degree of care and skill generally exercised by

other consultants under similar circumstances and conditions. TRC's findings and conclusions

must be considered not as scientific certainties, but rather as our professional opinion concerning

the significance of the limited data gathered during the course of the study. No other warranty,

express or implied is made. Specifically, TRC does not and cannot represent that the Site contains

no hazardous material, oil, or other latent condition beyond that observed by TRC during its study.

Additionally, TRC makes no warranty that any response action or recommended action will

achieve all of its objectives or that the findings of this study will be upheld by a Massachusetts

Department of Environmental Protection (MassDEP) audit.

2. This study and report have been prepared on behalf of and for the exclusive use of the MassDEP

and the City of New Bedford, solely for use in an environmental response actions at the New

on scientific tasks or procedures beyond the scope of described services or the time and budgetary

constraints imposed by Client. The work described in this report was carried out in accordance

with the Terms and Conditions referenced in our proposal.

4. In preparing this report, TRC has relied on certain information provided by state and local officials

and other parties referenced therein, and on information contained in the files of state and/or local

agencies available to TRC at the time of the study. Although there may have been some degree of

overlap in the information provided by these various sources, TRC did not attempt to

independently verify the accuracy or completeness of all information reviewed or received during

the course of this evaluation.

5. In the event that the Client or others authorized to use this report obtain information on

environmental or hazardous waste issues at the Site not contained in this report, such information

shall be brought to TRC's attention forthwith. TRC will evaluate such information and, on the

basis of that evaluation, may modify the conclusions stated in this report.

6. The purpose of this report was to assess the Site with respect to the requirements of the MCP. No

specific attempt was made to check on the compliance of present or past owners or operators of

the Site with federal, state, or local laws and regulations, environmental or otherwise.

7. The conclusions and recommendations contained in this report are based in part upon the data

obtained from a limited number of soil samples obtained from widely spread subsurface

explorations. The nature and extent of variations between these explorations may not become

evident until further exploration. If variations or other latent conditions then appear evident, it

will be necessary to reevaluate the conclusions and recommendations of this report.

8. Where quantitative laboratory analyses have been conducted by an outside laboratory, TRC has

relied upon the data provided, and has not conducted an independent evaluation of the reliability

of these data.

9. The conclusions and recommendations contained in this report are based in part upon various

types of chemical data and are contingent upon their validity. These data have been reviewed and

interpretations made in the report. As may be indicated within the report, some of these data may

be preliminary “screening” level data, and should be confirmed with quantitative analyses if more

specific information is necessary. Moreover, it should be noted that variations in the types and

concentrations of chemicals and variations in their flow paths may occur due to seasonal water

table fluctuations, past disposal practices, the passage of time, and other factors. Should additional

chemical data become available in the future, these data should be reviewed by TRC and the

conclusions and recommendations presented herein modified accordingly.

10. Chemical analyses have been performed for specific parameters during the course of this Site

assessment, as described in the text. However, it should be noted that additional chemicals not

searched for during the current study may be present at the Site.

11. TRC's risk evaluation was performed in accordance with generally accepted practices of the

MassDEP and other consultants undertaking similar studies. The findings of the risk evaluation

are dependent on numerous assumptions and uncertainties inherent in the risk assessment process.

Sources of uncertainty may include the description of Site conditions and the nature and extent of

chemical distribution and the use of toxicity information. Consequently, the findings of the risk

assessment are not an absolute characterization of actual risks, but rather serve to highlight

potential sources of risk at the Site. Although the range of uncertainties has not been quantified,

the use of conservative assumptions and parameters throughout the assessment would be expected

to err on the side of protection of human health and the environment.

DATA USABILITY ASSESSMENT

Page 1 of 5

Data Usability Assessment: Elco Dress Site, New Bedford, MA

1: Discuss appropriateness of selected analytical methods to quantitatively support disposal site’s Permanent Solution Statement. Discuss any impacts to the data used to support the Permanent Solution Statement if generated with non-CAM methods. Justify that the data used to support the Permanent Solution Statement is adequate in spite of the use of non-CAM methods.

Appropriateness of Analytical Methods Used

• The following methods were utilized to respond to all contaminants of concern: Soil: VOCs, EPH, PCB Aroclors, and metals Groundwater: VOCs, EPH, total and dissolved metals

• Tables 1 and 2 of the DUA identifies all samples and parameters used for the Permanent Solution Statement and included in this data usability assessment.

• All soil and groundwater sample analyses were performed using the CAM.

➢ Soil samples analyses were performed prior to July 2010 and were therefore performed in accordance with the 2004 CAM. Mercury analyses were not in accordance with the more recent 2010 CAM which requires the use of a larger sample aliquot (0.6 grams) in the sample digestion. The representativeness of the mercury results may be affected. However, since all mercury results were significantly below the project action levels, the use of a smaller sample aliquot (0.1 to 0.3 grams) in the sample digestion most likely did not have an adverse effect on the sample results.

2: Discuss appropriateness of selected analytical methods’ Reporting Limits (RL) to quantitatively support the disposal site’s Permanent Solution Statement.

• Analytical reporting limits, as documented by the laboratory, meet or exceed sensitivity requirements required to assess level of risk and cleanup standards for contaminants of concern previously identified for this response action for soil samples.

3: Discuss laboratory performance criteria and data quality indicators utilized to assess overall Analytical Accuracy (continuing calibration, laboratory control spikes, etc.) and Analytical Precision (laboratory duplicates, laboratory control spike duplicates, etc.) CAM Data: Review Certification Form and discuss data quality issues noted in narrative. Non-CAM Data: Discuss data quality indicators used to assess data and any data quality issues noted.

( ) Meets all CAM requirements and performance standards without qualification. (√) Does not meet all CAM requirements and performance standards without qualification. If NO, discuss

data usability implications No potentially significant issues associated with the soil and groundwater. Data usability was not adversely affected by the remaining data issues listed below as these issues would not cause a significant bias to the reported values whereby the exceedance of a project action level (i.e., Method 1 standard) would change or the presence or absence of a contaminant would change or the affected compounds were not considered to be contaminants of concern based on site history. Accuracy: Low Biases Soil:

• Low recovery of EPH in LCS and/or LCS duplicate: P-Elco-SB-7 (5-7). Precision: Soil

• High variability of isopropylbenzene in LCS/LCS duplicate: P-Elco-SB-1 (7), P-Elco-SB-2 (3), P-Elco-SB-2 (7), P-Elco-SB-3 (6).

• High variability of bromodichloromethane, ethyl tert-butyl ether, 1,2-dibromo-3-chloropropane, trans-1,2-dichloroethene, diisopropyl ether, and methyl-tert butyl ether in LCS/LCS duplicate: .P-Elco-SB-6 (7), P-Elco-SB-5 (5), P-Elco-SB-7 (3), P-Elco-SB-7 (7), P-Elco-SB-10 (3), P-Elco-SB-10 (7), P-Elco-SB-8 (7), P-Elco-SB-8 (5), P-Elco-SB-9 (3), P-Elco-SB-9 (10), P-Elco-SB-4 (7).

• High variability of chromium in in laboratory duplicate: P-Elco-SB-7 (0-3), P-Elco-SB-7 (5-7), P-Elco-SB-10 (0-3), P-Elco-SB-10 (5-7), P-Elco-SB-8 (0-3), P-Elco-SB-9 (0-3), P-Elco-SB-9 (5-7), P-Elco-SB-4 (5-7), P-Elco-SS-2 (0-1), P-Elco-SS-3 (0-1), P-Elco-SS-1 (0-1), 3P-Elco-SB-2 (7), P-Elco-SB-8 (5-7).

• High variability of antimony in LCS/LCSD: P-Elco-SB-7 (0-3), P-Elco-SB-7 (5-7), P-Elco-SB-10 (0-3), P-Elco-SB-10 (5-7), P-Elco-SB-8 (0-3), P-Elco-SB-9 (0-3), P-Elco-SB-9 (5-7), P-Elco-SB-4 (5-7), P-Elco-SS-2 (0-1), P-Elco-SS-3 (0-1), P-Elco-SS-1 (0-1), 3P-Elco-SB-2 (7), P-Elco-SB-8 (5-7).

Groundwater

• High variability of EPH in LCS/LCSD: all groundwater samples.

Data Usability Assessment: Elco Dress Site, New Bedford, MA

4: Discuss laboratory performance criteria and data quality indicators utilized to assess overall Field Data Usability (sample preservation compliance, sample subsampling/compositing, field QC samples, etc.)

Sample Preservation: Sample preservation procedures were performed as per required methods for all rounds of soil sampling. Field QC: Accuracy: soil and groundwater data assessed using MS/MSD analyses, sample preservation, and cooler temperature blanks for all coolers. Precision: soil and groundwater data assessed using field duplicates and MS/MSD analyses.

• Soil MS/MSDs: P-Elco-SB-2 (3) (PCBs Aroclors), P-Elco-SB-2 (0-3) (EPH), P-Elco-SB-8 (7) (metals and mercury).

• Groundwater MS/MSDs: TRC-14 (metals and mercury).

• Soil Field Duplicates: P-Elco-SB-7 (3), P-Elco-SB-10 (0-3), P-Elco-SB-8 (0-3), P-Elco-SB-9 (10) (VOCs, EPH, metals, mercury).

• Groundwater Field Duplicates: TRC-14 (VOCs, total metals, total mercury). Potentially significant issues associated with the soil and groundwater samples are summarized below. Issue #1: The samples were unpreserved for the VOC analyses of soil samples MW-3 (5-6), and MW-04 (5-6.5) therefore the results were rejected. Justification for Issue #1: Although these result are not usable for VOCs, many other sample results exist to adequately quantify the EPC in soil in the risk assessment process. Therefore, the rejection of the VOC data in these samples did not significantly affect the outcome or conclusions of this Permanent Solution Statement. Data usability was not adversely affected by the data issues listed below as these issues would not cause a significant bias to the reported values whereby the exceedance of a project action level (i.e., Method 1 standard) would change or the presence or absence of a contaminant would change or the affected compounds were not considered to be contaminants of concern based on site history. Accuracy of Field QC: Low Biases Soil:

• Low recovery of antimony in MS: P-Elco-SB-7 (0-3), P-Elco-SB-7 (5-7), P-Elco-SB-10 (0-3), P-Elco-SB-10 (5-7), P-Elco-SB-8 (0-3), P-Elco-SB-9 (0-3), P-Elco-SB-9 (5-7), P-Elco-SB-4 (5-7), P-Elco-SS-2 (0-1), P-Elco-SS-3 (0-1), P-Elco-SS-1 (0-1), 3P-Elco-SB-2 (7), P-Elco-SB-8 (5-7).

• Low recovery of EPH: P-Elco-SB-1 (5-7). Low Biases Groundwater:

• Low recovery of silver in MS: all groundwater samples. Precision:

• No issues noted.

5: Analytical Completeness of Data Used to Support the Permanent Solution Statement : Discuss any data rejected pursuant to Appendix II, Rejection Criteria – Analytical Data Usability Assessments

• >90% analytical completeness achieved for all site data.

• The following are gross failures of quality control in the analytical procedures: o The samples were unpreserved for the VOC analyses of soil samples MW-3 (5-6), and

MW-04 (5-6.5) therefore the results were rejected.

dichlorodifluoromethane, 2-hexanone, and bromomethane.

The results of analyses reported only relate to samples submitted to the Con-Test Analytical Laboratory for testing.

I certify that the analyses listed above, unless specifically listed as subcontracted, if any, were performed under my direction according to the approved methodologies listed

in this document, and that based upon my inquiry of those individuals immediately responsible for obtaining the information, the material contained in this report is, to the

best of my knowledge and belief, accurate and complete.

FLAG/QUALIFIER SUMMARY

* QC result is outside of established limits.

� Wide recovery limits established for difficult compound.

� Wide RPD limits established for difficult compound.

# Data exceeded client recommended or regulatory level

Percent recoveries and relative percent differences (RPDs) are determined by the software using values in the

calculation which have not been rounded.

No results have been blank subtracted unless specified in the case narrative section.

RL Reporting Limit

DL Method Detection Limit

MCL Maximum Contaminant Level

ND Not Detected

Either laboratory fortified blank/laboratory control sample or duplicate recovery is outside of control limits, but

the other is within limits. RPD between the two LFB/LCS results is within method specified criteria.

L-07


the other is within limits. RPD outside of control limits. Reduced precision anticipated for any reported result for

this compound.

L-07A

Compound classified by MA CAM as difficult with acceptable recoveries of 40-160%. Recovery does not meet

70-130% criteria but does meet difficult compound criteria.

L-14

Matrix spike recovery is outside of control limits. Analysis is in control based on laboratory fortified blank

recovery.Possibility of sample matrix effects that lead to low bias for reported result or non-homogeneous sample

aliquot cannot be eliminated.

MS-07

Either matrix spike or MS duplicate is outside of control limits, but the other is within limits. RPD between the

two MS/MSD results is within method specified criteria.

MS-22

Duplicate RPD is outside of control limits. Outlier can be attributed to sample non-homogeneity encountered

during sample prep.

R-02

Laboratory fortified blank duplicate RPD is outside of control limits. Reduced precision is anticipated for any

reported value for this compound.

R-05

Continuing calibration did not meet method specifications and was biased on the low side for this compound.

Increased uncertainty is associated with the reported value which is likely to be biased on the low side.

V-05

Response factor is less than method specified minimum acceptable value. Reduced precision and accuracy may

be associated with reported result.

V-16

Continuing calibration did not meet method specifications and was biased on the high side. Data validation is not

affected since sample result was "not detected" for this compound.

FLAG/QUALIFIER SUMMARY

* QC result is outside of established limits.

� Wide recovery limits established for difficult compound.

� Wide RPD limits established for difficult compound.

# Data exceeded client recommended or regulatory level

Percent recoveries and relative percent differences (RPDs) are determined by the software using values in the

calculation which have not been rounded.

No results have been blank subtracted unless specified in the case narrative section.

RL Reporting Limit

DL Method Detection Limit

MCL Maximum Contaminant Level

ND Not Detected


the other is within limits. RPD outside of control limits. Reduced precision anticipated for any reported result for

this compound.

L-07A

Compound classified by MA CAM as difficult with acceptable recoveries of 40-160%. Recovery does not meet

70-130% criteria but does meet difficult compound criteria.

L-14

Matrix spike recovery is outside of control limits. Analysis is in control based on laboratory fortified blank

recovery.Possibility of sample matrix effects that lead to low bias for reported result or non-homogeneous sample

aliquot cannot be eliminated.

MS-07

Laboratory fortified blank duplicate RPD is outside of control limits. Reduced precision is anticipated for any

reported value for this compound.

R-05

Elevated reporting limit based on lowest point in calibration.

MA CAM reporting limit not met.

RL-07

Surrogate recovery is outside of control limits, matrix interference suspected. Reanalysis yielded similar surrogate

non-conformance.

S-19

Continuing calibration did not meet method specifications and was biased on the low side for this compound.

Increased uncertainty is associated with the reported value which is likely to be biased on the low side.

V-05

Response factor is less than method specified minimum acceptable value. Reduced precision and accuracy may

be associated with reported result.

Cyanide Calculations

The soil cyanide concentration limit set to protect a child resident against an acute, potentially lethal one-time dose of cyanide

from incidental ingestion of contaminated soil is 100 mg/kg soil. This is the concentration of available cyanide in soil below which

acute human health effects would not be expected following a one-time exposure. This soil concentration is calculated using

the equation below with a pica-type soil ingestion of 1000 mgsoil and an available cyanide dose limit of 0.01 mg/kgbody weight.

MassDEP’s guidance on evaluating the risk from a one-time cyanide dose considers cyanide’s potentially lethal effects

as well as information on cyanide metabolism:

Cyanides are detoxified rapidly by the body, and a large acute dose which overwhelms the

detoxification mechanism is potentially more toxic than the same dose distributed over a

period of hours. (MassDEP Background Documentation for the Development of an Available Cyanide Benchmark Concentration ,

originally dated October 1992, Modified August 1998)

Assessment of a potential one-time dose requires an estimate of the maximum soil concentration the receptor could contact at any one

time. The average soil concentration within a typical exposure area will underestimate the potential one-time dose. Therefore,

to assess the acute risk of a one-time potentially lethal dose, the EPC for cyanide should be a conservative estimate of the maximum

soil concentration.

The residential soil concentration limit to protect against adverse effects from an acute (one-time) exposure to cyanide is 100 mg/kg.

acute human health effects would not be expected following a one-time exposure. This soil concentration is calculated using the

equation below with a one-time soil ingestion estimate of 50 mgsoil and an available cyanide dose limit of 0.01 mg/kgbody weight.





period of hours. (MassDEP Background Documentation for the Development of an Available Cyanide Benchmark Concentration, originally dated October 1992, Modified August 1998)

Assessment of a potential one-time dose requires an estimate of the maximum soil concentration the trespasser could contact

at any one time. The average soil concentration within a typical exposure area will underestimate the potential one-time dose.

Therefore, to assess the acute risk of a one-time potentially lethal dose, the EPC for cyanide should be a conservative estimate

of the maximum concentration.

The construction worker soil concentration limit to protect against adverse effects from an acute (one-time) exposure to cyanide is 12,000 mg/kg.

If values are not available for calculation, result is NA.

(8) Hv,TS = Hv,B*[(1-TS/TC)/(1-TB/TC)]n; if values are not available for calculation, result is NA.

(9) HTS = EXP[-Hv,TS/Rc*(1/TS-1/TR)]*HR; if values are not available for calculation, result assumed to be HR


(11) Refer to 12 SCS soil types - if no site-specific information is available, use SCL for screening.

(20) kv = ki,v * krg; note that the model is very sensitive to this parameter and if site-specific values are available, they should be used.

(21) Csource = H'TS * CR * Conv01 * b / (w,v + Kd * b + H'TS * a,v) * Conv02

(22) For screening, assume a trench 4 ft deep, 3 ft wide, 30 ft long and an air exchange rate of 60/hr. The air exchange rate is based on the assumption

that the wind speed in the trench is a small fraction of the ground wind speed and that it could take up to 1 minute for a contaminant to be

cleared from the trench air space.
