1.0 INTRODUCTION

BL Companies was retained by the State of Connecticut Department of Transportation

(ConnDOT) to conduct a Task 210 Subsurface Site Investigation (SSI) in support of ConnDOT

Project No. 92-0672, Capacity and Operational Improvements on Route 69 in the Vicinity of

Route 15 in New Haven and Woodbridge, Connecticut. This report provides a brief description

and history of the project area, a discussion of the local environment and receptors, the

investigation rationale, a summary of the data obtained during the investigation, an interpretation

of the results with respect to the appropriate regulatory criteria, and recommendations.

1.1 Background and Purpose

The project corridor is located along Route 69 between Lucy Street in Woodbridge, Connecticut

and Glen View Terrace in New Haven, Connecticut. The primary purpose of this project is to

improve capacity and operation deficiencies on Route 69 in the vicinity of the Route 15

Interchange 59. This project involves minor widening on Route 69 in the northbound and

southbound direction and Route 15 exit ramps to alleviate delays and queue lengths. In addition,

the project includes the installation of new sidewalks, ramps, and crosswalks to facilitate

pedestrian movement along Route 69, and on Route 69 at the Route 63 intersection. The Site’s

location and pertinent features are depicted on the enclosed Site Location Map (Figure 1) and

Site Investigation Plans (ENV-01 through ENV-03) in Appendix A.

The purpose of this Task 210 SSI is to collect soil and groundwater data in order to evaluate

whether the proposed construction activities require management of contaminated soil and

groundwater.

1.2 Previous Environmental Reports

Prior to the preparation of this Task 210 SSI, BL Companies was retained by ConnDOT to

conduct a Task 110 for the improvements on Route 69 in the vicinity of Route 15 in New Haven

and Woodbridge, CT. The findings of this report are briefly summarized below:

Task 110 Corridor Land Use Evaluation, Improvements on Route 69 in the Vicinity of Route 15,

New Haven and Woodbridge, Connecticut, BL Companies, dated May 2016

The objective of the Task 110 was to assess the relative environmental risk associated with

current and former land uses within the project corridor and vicinity; to evaluate whether the

project activities may encounter hazardous wastes, contaminated materials, or other regulated

substances; and to evaluate whether further investigation of the project corridor is warranted.

The Task 110 included the evaluation of 35 parcels, of which 11 were assigned a “high risk” and

4 were assigned a “moderate risk”, and 20 were assigned a “low risk” designation. The high,

moderate, and low risk parcels include the following:

2.0 LOCAL ENVIRONMENT AND RECEPTORS

2.1 Surficial Geology

According to the United States Geologic Society (U.S.G.S.) Surficial Materials Map of

Connecticut, dated 1992, the surficial geology of the project corridor consists of sand and gravel

overlying sand. Sand and gravel is generally less than 20 feet thick, horizontally bedded, and

overlies thicker, inclined layers of sand.

Based on observations during boring installation, surficial materials consist of brown fine to

coarse sand with silt and varying amounts for fine to coarse gravel, which is underlain with

red/brown fine to coarse sand with fine to coarse gravel and silt. Petroleum staining and odor

were observed in boring B-4, between 1 and 10 ftbg. Boring logs are included as Appendix C.

2.2 Bedrock Geology

According to the “Bedrock Geological Map of Connecticut”, dated 1985, bedrock beneath the

project area is mapped as New Haven Arkose, which is characterized by red, pink, and gray

coarse-grained, locally conglomeratic, poorly sorted and indurated arkose, interbedded with

brick-red micaceous, locally shaly siltstone and fine-grained feldspathic clayey sandstone.

Bedrock was not encountered during this investigation.

2.3 Groundwater

According to the Connecticut Department of Energy and Environmental Protection (CTDEEP)

Water Quality Classifications Map of New Haven, Connecticut (November 2016), groundwater

within the southernmost portion of the project, from Route 15 and south, is located in an area

with “GA/GAA” classified groundwater. “GA/GAA” classified groundwater is considered

suitable for direct human consumption without the need for treatment; however, the water quality

within this area may not be meeting current standards. Groundwater within the remaining

portion of the project, from Route 15 and north, is classified as “GA”, which is located within an

area of existing and potential private or public water supply wells. The Site is not located in an

Aquifer Protection Area. During this Task 210 SSI, groundwater was encountered at

approximately 7 to 9 ftbg.

Based on the presence of the West River, the general direction of groundwater flow is inferred to

be south/southeast.

2.4 Surface Water

Lily Pond and West River run adjacent to the project area to the east. According to the above

referenced CTDEEP map, Lily Pond and West River are classified as a Class “A” surface waters.

The designated uses for Class “A” surface waters are existing or proposed drinking water

supplies, habitat for fish and other aquatic life and wildlife, recreation, navigation, water supply

for agriculture and industry.

State Project No. 92-0672; Assignment No. 314-5332

3.0 FIELD INVESTIGATION AND SAMPLING METHODS

This Task 210 SSI included the advancement of 13 soil borings, installation of two temporary

monitoring wells, and collection and laboratory analysis of 20 soil samples and two groundwater

samples. BL Companies subcontracted Cummins Envirotech, Inc. (CEI) of Old Lyme,

Connecticut to advance borings and install the temporary wells. The soil boring locations are

depicted on ENV-01 through ENV-03.

Soil and groundwater samples were analyzed for regulated constituents of concern associated

with the historical use of adjacent properties. Table 1 in Appendix B provides a summary of the

sampling rationale and the laboratory analyses requested for each soil and groundwater sample.

The following sections summarize the field investigation and sampling methodologies used

during this investigation.

3.1 Soil Boring Installation and Sampling

On November 16, 2016, seven soil borings, identified as B-1 through B-7, were advanced to

depths ranging from 5 to 15 ftbg using a track-mounted Geoprobe direct-push drill rig. Soil

samples were obtained continuously during advancement of borings using a 2-inch diameter,

5-foot long, thin-walled, sampling device equipped with disposable acetate liners. Six borings,

identified as HA-1 through HA-6, were advanced utilizing a hand auger to a depth of two ftbg.

A representative portion of each soil core was screened with a PID to detect estimated quantities

of total VOCs in vapor emitted from the soil. The PID was equipped with a 10.6 eV bulb and

was calibrated to isobutylene standard gas (100 parts per million (ppm)). The results of the PID

screening were 0.0 ppm for all samples screened with the exception of B-4 which exhibited

elevated PID readings ranging from 300 to 2,341 ppm. Petroleum staining and odor were also

observed throughout the soil boring. PID readings are provided on the boring logs in

Appendix C.

Soil samples were selected for laboratory analysis based the anticipated depth of construction

activities, observations (physical evidence of contamination and/or lithology change), and the

results of the field screening. The samples were submitted under proper chain-of-custody to

Accutest New England (Accutest) of Marlborough, Massachusetts, a State of Connecticut

Department of Public Health certified environmental testing laboratory.

3.2 Groundwater Sampling

Following soil sampling, a 1-inch diameter PVC screen and riser pipe were inserted into borings

B-1 and B-3, as temporary sampling wells. After the groundwater in the temporary wells was

allowed to equilibrate, the wells were sampled at a low-flow rate using a peristaltic pump.

Groundwater was pumped directly into appropriate sample containers provided by the laboratory

and placed in a cooler with ice. The groundwater samples were submitted to Accutest under

proper chain-of-custody control.

Task 210 – Subsurface Site Investigation -7- Project No.14EC0047

Improvements on Route 69 In the Vicinity of Route 15 January 2017

State Project No. 92-0672; Assignment No. 314-5332

4.0 REGULATORY CRITERIA

The soil analytical results were compared to the numeric criteria listed in the Connecticut DEEP

Remediation Standard Regulations (RSRs), sections 22a-133k-1 through 22a-133k-3 of the

Regulations of Connecticut State Agencies, dated June 2013, and also compared to the published

2015 numeric criteria for additional polluting substances not promulgated in the June 2013

RSRs. The RSRs were developed by the DEEP to define the remediation performance standards

for soil and groundwater to be protective of human health and the environment.

The RSRs apply specifically to sites at which remedial actions are required by the DEEP under

Chapters 445 or 446k of the Connecticut General Statutes (CGS) such as under an administrative

order, subsequent to a transfer of an establishment under CGS Section 22a-134a, and to sites that

are enrolled in a Voluntary Remediation Program under CGS Sections 22a-133x or 22a-133y.

The project limits are not currently regulated under any of these State statutes. However, BL

Companies used the numeric criteria stated above as guidance to evaluate the data regarding

concentrations of regulated compounds detected in soil. DEEP defines polluted soil as

containing any substance at a concentration above the analytical detection limit. Contaminated

soil is defined as any substance whose concentration exceeds the numeric criteria of the RSRs.

Both classifications require special handling, re-use, and disposal requirements.

Based on discussions between ConnDOT and DEEP, the numeric criteria in the RSRs do not

provide the best method for construction projects to determine whether treatment of groundwater

is necessary prior to discharge. In accordance with DEEP guidance, groundwater analytical

results were compared to the effluent limits established under both DEEP General Permits for the

Discharge of Groundwater Remediation Wastewater (to Sanitary or Surface Water) for the

purpose of groundwater management.

The following sections provide a brief summary of the soil and groundwater criteria utilized

during this Task 210 SSI.

4.1 Soil Criteria

Direct Exposure Criteria (DEC)

The DEC are designed to protect human health from risks associated with exposure to pollutants

in contaminated soil within 15 feet of the ground surface.

The RSRs provide two sets of DEC, one for residential land use (RES DEC) and another for

industrial/commercial land use (I/C DEC). The CTDEEP RSRs define “residential activity”

under CGS Section 22a-133k-1(a) to include any activity related to a residence or dwelling, or to

a school, hospital, day care center, playground, or outdoor recreation area. Remediation to the

RES DEC is required unless an ELUR is recorded that restricts residential use. For this project,

BL Companies compared the soil analytical results to both the RES DEC and I/C DEC.

Improvements on Route 69 In the Vicinity of Route 15 January 2017

State Project No. 92-0672; Assignment No. 314-5332

Pollutant Mobility Criteria (PMC)

The PMC are designed to protect groundwater quality by reducing or eliminating the potential

for migration of pollutants to groundwater from contaminated soil. The RSRs provide two sets

of PMC based on the groundwater classification of the Site, as designated by DEEP. In a “GA”

groundwater classification area, the GA PMC apply to soil located from the ground surface to the

depth of the seasonal low water table. As the project area is in a “GA” area, BL Companies

compared the soil analytical results to the GA PMC.

4.2 Groundwater Criteria

Maximum Concentration Limits (MCLs) Established in DEEP General Permits for Discharge of

Groundwater Remediation Wastewater Directly to Surface Water or Sanitary Sewer

Maximum Concentration Limits (MCLs) established in DEEP General Permits for Discharge of

Groundwater Remediation Wastewater Directly to Surface Water or Sanitary Sewer apply to

impacted groundwater that is discharged to surface water or sanitary sewer during construction.

In order to evaluate whether construction dewatering would require treatment prior to discharge,

BL Companies compared the groundwater analytical results to the Remediation Waste Water

Discharge MCLs.

summarized in Table 3 in Appendix B. The groundwater analytical laboratory report is

included in Appendix D.

VOCs

Benzene was detected in groundwater sample B-3/GW at a concentration below the Surface

Water and Sanitary Sewer MCLs. VOCs were not detected above the detection limits in the

groundwater sample B-1/GW.

Metals

• Total arsenic, copper, and lead were detected in groundwater sample B-1/GW at

concentrations above their respective Surface Water Discharge MCLs, but below their

respective Sanitary Sewer Discharge MCL. Dissolved arsenic, copper, and lead were

not detected in either sample.

• Total chromium and zinc were detected in groundwater sample B-1/GW at

concentrations below the DEEP General Discharge Permit MCLs. Dissolved chromium

and zinc were not detected in either sample.

• Total and dissolved barium were detected in groundwater samples B-1/GW and

B-3/GW at concentrations below the DEEP General Discharge Permit MCLs.

ETPH, SVOCs, Pesticides, and PCBs

ETPH, SVOCs, pesticides, and PCBs were not detected above the detection limits in either of the

groundwater samples.

5.3 Quality Assurance (QA)/Quality Control (QC) Results

All samples were analyzed using the DEEP Reasonable Confidence Protocol (RCP), where

applicable, and meet the RCP requirements. BL Companies also thoroughly reviewed the

laboratory RCP Certification Report to evaluate the reliability of the analytical data. The case

narratives do not indicate any non-conformances that would affect the usability of the data. All

reportable detection limits were below RSR criteria and DEEP General Discharge Permit MCLs.

Improvements on Route 69 In the Vicinity of Route 15 January 2017

State Project No. 92-0672; Assignment No. 314-5332

Soil

Trip blank samples were prepared at the laboratory and accompanied the sample containers from

the laboratory, to the Site, and back to the laboratory. The purpose of the trip blank samples was

to evaluate the potential for cross-contamination from the surrounding environment during

transport. The trip blank samples were analyzed for VOCs. VOCs were not detected in the trip

blank samples, indicating that there was likely no cross-contamination of the samples during

transportation.

A duplicate soil sample was obtained from one randomly selected soil sample location to

evaluate the accuracy of the laboratory analytical data, measured as Relative Percent Difference

(RPD) as defined by the DEEP Laboratory Quality Assurance and Quality Control Guidance

Document, dated May 2009, revised December 2010. The duplicate was obtained from sample

HA-6 (0-2’) and analyzed for VOCs, ETPH, PCBs, pesticides, and total and TCLP RCRA 8

metals. All RPDs were lower than the 50 RPD acceptable limit for non-aqueous samples.

Groundwater

A field blank sample was collected by running de-ionized water through the sampling equipment

and into the laboratory provided sample containers. The purpose of a field blank sample is to

evaluate the potential for cross-contamination due to the sampling equipment or technique. The

field blank sample was analyzed for VOCs, SVOCs, ETPH, PCBs, pesticides, and total and

dissolved metals. No constituents were detected in the field blank sample.

Trip blank samples were prepared at the laboratory and accompanied the sample containers from

the laboratory, to the Site, and back to the laboratory. The purpose of the trip blank samples was

to evaluate the potential for cross-contamination from the surrounding environment during

transport. The trip blank samples were analyzed for VOCs. VOCs were not detected in the trip

blank samples, indicating that there was likely no cross-contamination of the samples during

transportation.

A duplicate sample was collected from B-3/GW to evaluate the accuracy of the laboratory

analytical data, measured as RPD. The duplicate sample was analyzed for VOCs, SVOCs,

ETPH, PCBs, pesticides, and total and dissolved RCRA 8 metals, copper, and zinc. All RPDs

were lower than the 30 RPD acceptable limit for aqueous samples.

6.0 POTENTIAL SOURCES OF CONTAMINATION, RECEPTORS, AND

IDENTIFIED PRELIMINARY AREAS OF ENVIRONMENTAL CONCERN

The following provides a summary of the potential sources of soil and groundwater

contamination identified during completion of this Task 210 SSI, an evaluation of potential

pathways for migration, and the identification of a preliminary Area of Environmental Concern

(AOEC) and Groundwater Area of Environmental Concern (GW AOEC) within the project area.

AOEC 1 (Site-Wide)– Contaminated Soil in the Vicinity of Borings B-1 through B-7 and

HA-1 through HA-6

ETPH, VOCs, SVOCs pesticides and lead were detected at concentrations exceeding the RES

DEC, I/C DEC, and/or GA PMC in soil samples collected at depths ranging from 0 to 10 ftbg.

The source of the contamination is likely historical uses of adjacent parcels, incidental release

from vehicles or run off from Route 69, and urban fill containing coal, ash, and slag.

Proposed work within AOEC 1 includes new road construction, relocation/reconstruction of existing

roadways and sidewalks, drainage improvements, utility relocations, and excavations in excess of

three feet in depth. Therefore, any soil removed from AOEC 1 should be reused onsite or

handled as controlled material. Potential receptors of the impacted soil include workers involved

in the construction activities, particularly during excavation activities.

GW AOEC – Contaminated Groundwater in the Vicinity of Borings B-1.

Total arsenic, copper, and lead were detected at concentrations above the Surface Water

Discharge MCL in the groundwater sample collected from boring B-1.

It is unknown whether excavations will be performed below the water table during the project.

However, based on the results of this investigation, if groundwater within the GW AOEC

requires dewatering, it will require special management or treatment. Potential receptors of the

impacted groundwater include workers involved in the dewatering activities.

Improvements on Route 69 In the Vicinity of Route 15 January 2017

State Project No. 92-0672; Assignment No. 314-5332

7.0 CONCLUSIONS AND RECOMMENDATIONS

Based on the analytical data collected by BL Companies, a preliminary AOEC and GW AOEC

were identified within the project area, as summarized below:

• Soil within AOEC 1 (Site-Wide) contains ETPH, SVOCs, VOCs, pesticides, and lead

at concentrations exceeding RSR numeric criteria and therefore classified as

contaminated material. This contaminated material must be managed and handled as

controlled material per ConnDOT specifications.

• Groundwater within GW AOEC contains total arsenic, copper, and lead above the

General Permit MCL for Surface Water. Therefore, groundwater within GW AOEC

will require special management or treatment if encountered during excavations for

the project.

Based on the results of this Task 210 SSI, BL Companies recommends that a Task 310 – Plans,

Specifications, and Estimates be assigned to prepare plans and specifications for the proper

management and/or disposal of contaminated materials (soil and groundwater) that may be

reused, removed, handled, transported, or disposed of during construction activities and for the

establishment of appropriate worker health and safety protocols.
