3.0 PROBLEM DEFINITION

The Site is a former automotive sales and service facility. The facility is not currently in

operation and is vacant. The Site contains an approximate 7,840 square foot building located

within an approximate 0.467-acre parcel. Figures 1 and 2 depict the Site location and pertinent

details. The Site is abutted to the northwest by a commercial/light industrial trucking facility; to

the northeast by a former gasoline fueling station; to the southwest by Berkshire Street, beyond

which is an undeveloped lot and light industrial building; and to the southeast by Main Street,

beyond which are several light industrial/commercial buildings and a waste water treatment

facility (Figure 3).

Based on a TBA prepared in November 2008, the following Recognized Environmental

Conditions (RECs) were identified:

• The abutting property to the northeast has been occupied by a gasoline station for more

than 30 years. Based upon its proximity to the Site, there is a potential that petroleum

releases from associated underground storage tanks (USTs), pump islands, and

ancillary piping may have impacted the Site. Additionally, at least one gasoline UST was

historically located at or near the northeastern boundary of the Site.

• The Site is located in an area with industrial uses since approximately 1900. Volatile

Organic Compounds (VOCs) have been detected in groundwater monitoring wells at a

downgradient property. There is a potential that the Site has been impacted by VOCs or

other compounds from industrial properties in the vicinity.

• Suspect UST vent pipes were observed on the northwestern side of the Site building.

Based upon City of Holyoke Fire Department records, it is possible that USTs permitted

in 1950 and 1970 are still present at the Site.


• Two floor drains and a trench drain were observed during Site reconnaissance activities.

Oily liquid was observed to be pooled in and around the drains. Additionally, the

discharge points of these drains are unknown. There is a potential that a release to the

environment from these drains has occurred via pipe leaks which may have migrated

through a Site leaching system.

• Large amounts of staining and pooling of oily liquids were observed in the central and

western portions of the Site building around a fuel oil above-ground storage tank (AST),

a heater, miscellaneous drums and debris, and in other areas. The concrete building

floor was observed to be compromised by cracks, creating a potential migration pathway

for contaminants to be released to soil and groundwater underlying the Site.

• Three former hydraulic lifts and one hydraulic reservoir were observed in the western

portion of the Site building. It is not known if additional hydraulic lift reservoirs are

present at the Site or if hydraulic reservoirs have resulted in a release at the Site.

Additional Site investigation work was required to evaluate the Site RECs. Nobis conducted a

Phase II investigation in 2011. The objective of the Phase II Site Investigation was: to assess

potential impact to soil and groundwater associated with historical Site activities and the RECs

identified in the 2008 TBA; to identify potential migration pathways of Site oil and/or hazardous

materials (OHM); to determine locations of former USTs; and, to characterize potential

hazardous building materials and associated debris. In order to achieve the objectives stated in

the FTWP/QAPPA, Nobis developed and implemented a Phase II program that included the

following elements:

• Ground Penetrating Radar (GPR) Survey to assess the presence of suspect exterior

USTs;

• Hazardous building materials survey, which included mold/fungi sampling, lead-based

paint (LBP) sampling, asbestos-containing materials (ACM) sampling, and a hazardous

materials inventory;

• Dye test, to evaluate the discharge points of interior drains; and,


• Subsurface soil boring and groundwater monitoring well installations, well elevation

survey, and groundwater sampling.

Based on the results of the 2011 investigation:

• The GPR survey identified two suspect USTs, two anomalous zones, and multiple

utilities. The two suspect USTs are located north of the building. The locations were

marked in the field at the time of the survey. Both USTs have associated fill and/or vent

pipes in close proximity to their identified locations. The two suspect USTs are depicted

on Figure 2.

• Concentrations of soil and groundwater have been impacted with concentrations of

petroleum hydrocarbon and chlorinated VOC constituents, which appear to be attributed

to former Site operations. Although the vertical and horizontal extent of impact has not

been delineated, the area of impact appears to be localized within the interior of the Site

building and has not migrated beyond the Site property boundary. There is a MCP 120-

Day Reporting Condition associated with the levels of petroleum and VOC contaminants

detected in Site soil and groundwater.

• Based on the results of the subsurface investigation, there do not appear to be

upgradient (off-Property) sources of Site contamination.

• The results of the dye test conducted at the Site identified that floor drains may

discharge to a nearby storm drain which subsequently discharge to a combined sewer

overflow (CSO) located south of the Site. Because the facility is currently inactive, there

is no ongoing discharge from the floor drains at the Site.

• The hazardous materials survey indicated the presence of ACM, LBP and mold in Site

building materials. An inventory of additional potential regulated and hazardous

materials was produced for the Site that included (but not limited to) fluorescent lights

and ballasts, five mercury thermostats, multiple 55-gallon drums, and additional

containers and/or tanks of suspect OHM.


3.1 Contaminants of Concern

Contaminants of concern (COCs) include chlorinated VOCs (CVOCs) and petroleum

hydrocarbons attributed to historic storage and usage of solvents and petroleum compounds

associated with the former automotive facility.

3.2 Historic Site Investigations

Based on the results of the investigation conducted by Nobis in 2011, the following

Massachusetts Contingency Plan (MCP) Reportable conditions were encountered at the Site:

• Nobis measured 0.03 feet (0.36”) thickness of light non-aqueous phase liquid (LNAPL)

at well NOB-101 on May 25, 2011, which is designated as a MCP 120-Day Reporting

Condition. Nobis field staff provided this information to Ms. Caprice Shaw of MassDEP

who was providing field oversight on the date of the groundwater sampling event.

• Soil samples collected from boring NOB-101 indicated concentrations of Extractable

Petroleum Hydrocarbons (EPH) (C19-C36 Aliphatic hydrocarbons and C11-C22

Aromatic hydrocarbons) at levels exceeding applicable MCP Reportable Concentrations

for Soil Category S-2 (RCS-2). The C19-C36 Aliphatic hydrocarbon concentration also

exceeded the MCP Upper Concentration Limit (UCL). NOB-101 is located within the

building footprint between two former hydraulic lifts. The samples were collected at

approximate depths of 8 and 10 feet below ground surface (bgs), indicating soil

contamination at or in the approximate smear zone of the water table. It is noted that the

horizontal and vertical extent of petroleum hydrocarbon impact within the area of NOB-

101 has not been delineated. Potential sources are the hydraulic lifts or USTs.

• Concentrations of VOCs (cis-1,2-Dichloroethylene [cis-1,2-DCE], trichloroethylene [TCE]

and vinyl chloride) were detected in groundwater collected from wells NOB-101 and

NOB-102 at levels exceeding MCP Reportable Concentrations for Groundwater

Category GW-2 (RCGW-2). There is a potential that Site groundwater may serve as a

potential migration pathway for VOCs, specifically to indoor air via the vapor intrusion

pathway. Since the Site is unoccupied, there are no current receptors to vapor intrusion

from Site groundwater. However, there is a potential of impact to future receptors.


Depth to groundwater at the Site has been observed from approximately 8 to 10 feet bgs.

Groundwater flows toward the Connecticut River, located approximately 1,150 feet southeast of

the Site.

3.3 Remedial Activities

No known remedial activities have been conducted.

3.4 Proposed Assessment Activities

Nobis proposes the collection of soil, groundwater, and soil gas samples to fill data gaps at

portions of the Site, specifically within the building footprint.

4.0 PROJECT DESCRIPTION AND TIMELINE

The objective for this FWTP/QAPPA is to delineate the extent of CVOC and petroleum

hydrocarbon-impact within the areas of groundwater monitoring wells NOB-101 and NOB-102

and to assess the potential of impacts to soil gas, as it relates to potential indoor air impacts.

This objective will be accomplished by advancing soil borings and installing groundwater

monitoring wells; advancing permanent soil gas points; and collecting soil, groundwater and soil

gas samples.

The following sections include a description of the Project and the Timeline to complete the

assessment activities.

4.1 Project Description

The TBA tasks to be completed include the following:

• Site Preparation – Update the Site-specific health and safety plan; and pre-mark Site for

Digsafe;

• Subsurface Investigation – Install soil borings, groundwater monitoring wells and soil

gas points; conduct soil, groundwater, and soil gas sampling; and,


• Report Preparation – Summarize and evaluate data; prepare the TBA report; and

develop cost estimate for remediation.

Media sampling will be conducted in accordance with the sampling design outlined in Section

5.0. Soil and groundwater data collected during the course of the TBA will be compared with

applicable MCP Method 1 Standards to assess potential risks to human health and the

environment associated with suspected COCs. Soil gas analytical results will be compared to

MassDEP residential soil gas screening values, as outlined in MassDEP’s Interim Final Vapor

Intrusion Guidance (WSC#-11-435).

4.2 Subsurface Investigations

A Site subsurface investigation is proposed to assess soil, groundwater and soil gas/indoor air

conditions. Personal protective equipment (PPE) and decontamination procedures are

discussed in the Site-specific Health and Safety Plan.

Nobis anticipates up 1 day of subsurface drilling oversight, including soil sampling, groundwater

monitoring well installation and development. Nobis anticipates an additional 1 day for

groundwater monitoring well and soil gas sampling.

Soil and Groundwater Sampling

• Up to three (3) soil borings will be advanced using a tracked geoprobe drill rig to a

maximum depth of 25 feet bgs in the overburden. Continuous sampling and field-

screening of soil will be conducted. Soil samples will be collected from the depths at

which visual or olfactory evidence of contamination is encountered. The investigation

will be conducted within the interior of the Site building. The borings will be identified as

“NOB-200-series”.

• Three of the soil borings will be completed as overburden groundwater monitoring wells.

The borings will be completed as 2-inch diameter flush-mount groundwater monitoring

wells.

Depth to groundwater at the Site has been observed from approximately 8 to 10 feet bgs.

Figure 2 illustrates the proposed soil boring and groundwater monitoring well locations.


The driller will advance the soil borings using direct push drilling methods. Soil samples will be

collected utilizing acetate soil sampler, advanced continuously. Soil samples will be screened

for total volatile organic compounds (TVOCs) using an organic vapor meter equipped with a

photoionization detector (10.6 eV lamp), and pursuant to the MassDEP soil jar headspace

method (Appendix B). Up to one soil sample will be collected from each soil boring and

submitted for laboratory analysis of VOCs, Volatile Petroleum Hydrocarbons (VPH) and target

analytes and Extractable Petroleum Hydrocarbons (EPH) and target analytes. Selection of soil

samples for analysis will be determined in the field based on field screening and observations at

the time of sample collection. Soil sample analyses are further described in Section 5.0.

Groundwater monitoring wells will be constructed of two-inch diameter schedule 40 polyvinyl

chloride (PVC) casing and 0.010-inch slot screen to an approximate depth of 20 ft bgs. Well

screen length will be determined in the field, based on Site observations. The wells will be

completed with flush-mount road boxes. Appropriate decontamination and well development

measures will be implemented as defined in the Generic QAPP [Nobis, 2010].

Groundwater samples will be collected to assess Site groundwater conditions. Nobis will

conduct one sampling event. After a minimum one-week stabilization period for the newly

installed wells, Nobis will collect groundwater samples from the three new Site monitoring wells.

Static groundwater levels will be measured at each location prior to the collection of

groundwater samples. Groundwater samples will be collected using EPA’s low flow/low stress

methodology via a peristaltic or bladder pump. The SOP for this methodology is located in the

Generic QAPP [Nobis, 2010]. Groundwater samples will be submitted for VOCs, VPH, and

EPH analyses. Groundwater sample analyses are further described in Section 5.0.

Soil Gas Sampling

• Nobis will install up to three (3) permanent soil gas vapor sampling points within the Site

building using a tracked geoprobe rig.

• The permanent sampling points will be constructed of polyvinyl chloride (PVC) riser

screen and a sampling valve. The points will be advanced to an approximate depth of

1.5 feet bgs.


• After one week of equilibration, Nobis will collect one grab soil gas vapor sample from

each sampling point using an evacuated 6 liter summa canister at a rate of 200 mL/min

for a 30 minute duration. Up to three samples will be collected for analysis of VOCs per

EPA Method TO-15 and petroleum hydrocarbons per MassDEP Method for Air

Petroleum Hydrocarbons (APH).

Figure 2 illustrates the proposed soil boring and groundwater monitoring well locations, and soil

gas points.

LNAPL Sampling

Nobis will collect a LNAPL sample from well NOB-101 using a peristaltic pump. The sample will

be transferred to a clean, unpreserved, 4-oz jar and placed on ice for laboratory analysis under

a chain of custody.

IDW

IDW, such as drill cuttings and development and purge water, will be managed in accordance to

the Generic QAPP [Nobis, 2010]. The final determination regarding potential off-Site disposal of

IDW will be determined upon the review of analytical results of the subsurface investigation

program.

4.3 Targeted Brownfields Assessment Report

Based on the results of the subsurface investigation described in Section 4.2, Nobis will prepare

a report summarizing the TBA activities performed at the Site. The report will include a cost

estimate for remedial activities. Laboratory data will be summarized in tables and sample

locations will be shown on figures. Data summaries will be evaluated by comparing the Site

data to MCP Cleanup standards. A discussion of QA/QC, including data validation results, will

also be provided.

4.4 Project Timeline

The anticipated schedule for this investigation is summarized in the attached Table 1.

analyses:

• VOCs per MassDEP CAM Method 8260B;

• EPH (with target analytes (PAHs)) by MassDEP EPH Method;


• VPH (with target analytes) by MassDEP VPH Method;

• One product (non-aqueous phase liquid [NAPL]) sample will be collected from

groundwater monitoring well NOB-101 for fingerprint analysis, to assess the type of

petroleum impact and potential presence of VOCs.

Three newly installed monitoring wells (Section 4.2) will be sampled during one groundwater

sampling event. One trip blank will be submitted for laboratory analysis of VOCs and one field

duplicate will be submitted for VOCs, EPH, and VPH analyses.

5.3 Soil Gas Analyses

Soil gas samples will be collected for the following analyses:

• Air-Phase Petroleum Hydrocarbons (APH) by MassDEP APH Method; and

• Reactive Cyanide by SW-846 Methods 9012 and 9014;

• Reactive Sulfide by SW-846 Methods 9030 and 9034; and

• TCLP Metals (if necessary).


One soil sample and one water sample will be collected following the subsurface investigation.

QA/QC samples will not be collected during IDW sampling. IDW will be managed in accordance

with the Generic QAPP [Nobis, 2010].

6.0 SAMPLING AND ANALYTICAL METHODS REQUIREMENTS

Table 3 summarizes the sampling and analytical method requirements for the subsurface

investigation at the Site. The approved SOPs for all proposed analytical methodologies have

been included in Nobis’ Generic QAPP, Revision 0 [Nobis, 2010] or in previously approved

FTWP/QAPPA. Appendix A and B of this FTWP/QAPPA include additional SOPs that are
