1.0 INTRODUCTION

On behalf of the Connecticut Department of Transportation (CTDOT), Diversified Technology

Consultants, Inc. (DTC), has prepared the following Task 210 Subsurface Site Investigation

Report (SSIR) in support of State Project No. 0171-0428, Wolcott Maintenance Facility Tank

Replacement in Wolcott, Connecticut.

1.1 Background and Purpose

The proposed project is at the CTDOT Maintenance Facility (“Site”) which is located at

1010 Wolcott Road, Wolcott, Connecticut and consists of the removal of the existing motor

fueling facility. The proposed work includes the removal of an existing fuel island, 4,000-

gallon diesel fuel underground storage tank (UST), 2,000-gallon fuel oil UST, 3,000-gallon

waste water holding UST, and all associated piping, appurtenances and concrete. The

fuel oil UST will be replaced with an above ground storage tank (AST) and the waste water

holding tank will be replaced with a new waste water holding UST.

The Task 210 SSIR was conducted to verify the absence or presence and location of

subsurface contamination, and to assess the potential pollutant impacts to be encountered

during construction for the proposed project. It is anticipated that Task 310 Plans,

Specifications and Estimate will subsequently be prepared to assess construction related

activities (i.e. proper storage, classification, transport and disposal of contaminate

materials), in relationship to the environmental conditions prevalent at the Site, as well as

specify remedial work to be included in the Contract Bid Documents.

2.0 LOCAL ENVIRONMENT AND RECEPTORS

The purpose of this project is to remove the existing motor fuel island, 4,000-gallon diesel fuel

underground storage tank (UST), 2,000-gallon fuel oil UST and associated piping, 3,000-gallon

waste water UST and all associated concrete.

This Task 210 SSIR was conducted in the areas of anticipated construction activities for the

proposed project. The site area and sample locations are depicted on Figure 2 – Subsurface

Site Investigation, Soil Boring Location Plan included at the end of this report.

2.1 Surficial Geology

According to CT Environmental Conditions Online (CT ECO), the surficial geology for the

Site is described as till.

2.2 Bedrock Geology

According to CT ECO, bedrock at the Site is the Straights Schist, described as a silvery to

gray coarse-grained schist.

2.3 Groundwater

According to CT ECO, groundwater at the Site is designated as “GA”. “GA” classified

groundwater is considered by the CT DEEP to be located within the area of existing

private drinking water supply wells or an area with the potential to provide water to public

or private water supply wells. The CT DEEP presumes that groundwater within a “GA”

area is suitable for human consumption without treatment.

2.4 Surface Water

An unnamed watercourse associated with Pellegrini Pond is located approximately 500

feet south of the Site, which also connects to the Mad River. Both watercourses are

designated as Class A. Surface waters of this designation are considered by the CT

DEEP as potential public supply and for habitat for fish and other aquatic life and wildlife,

recreation, navigation, and/or a water supply for industry or agriculture.

3.0 SUBSURFACE SITE INVESTIGATION

Based upon the anticipated construction activities and the existing surrounding land use, DTC

conducted a comprehensive sampling program within the project limits. The subsurface site

investigation was conducted in accordance with our task assignment and the approved Work

Plan dated June 2019. The following subsections detail the investigation which was conducted

within the project limits on June 25 and 26, 2019.

3.1 Soil Sample Collection and Analysis

Sixteen (16) borings, B1 through B16, were advanced within the project limits at the

locations shown on the attached Soil Boring Location Plan, Figure 2. The borings were

advanced to a depth of 15 feet below ground surface within the project limits, utilizing a

Geoprobe direct push unit. The boring locations were marked in the field and cleared by

a private utility and ground penetrating radar company, and the driller notified “Call Before

You Dig” prior to conducting intrusive activities.

The soil samples were visually inspected in the field for staining and soil boring logs were

generated by the licensed driller. In addition, the soil samples were screened in the field

for total volatile organic compounds utilizing a photoionization detector (PID).

Based upon field screening results and visual observations, one (1) soil sample from each

boring was collected, placed in laboratory-supplied glassware and stored in an ice-filled

cooler. If visual screening did not indicate contamination, the soil sample representing the

approximate bottom of the tank, 8 to 10-feet below grade, was collected for laboratory

analyses. All collected soil samples were analyzed for the following parameters:

• Volatile Organic Compounds (VOCs) - EPA Method 8260

• Semi-Volatile Organic Compounds (SVOCs) - EPA Method 8270

• Extractable Total Petroleum Hydrocarbons (ETPH) - Connecticut ETPH Method

• Total and SPLP RCRA 8 Metals – EPA Method SW846/6010

Field sampling protocols were performed in accordance with the DEEP’s Guidance for

Collecting & Preserving Soil & Sediment Samples for Laboratory Determination of Volatile

Organic Compounds document dated March 1, 2006. All boring locations were back-filled

Page 8: Diversified Technology Consultants, Inc. July 2019...Diversified Technology Consultants, Inc. July 2019 Task 210 – Subsurface Site Investigation Wolcott Maintenance Facility Tank

Diversified Technology Consultants, Inc. July 2019 Task 210 – Subsurface Site Investigation Wolcott Maintenance Facility Tank Replacement State Project No. 0171-0428, Assignment No. 218-5996 5

upon completion and all down-hole sampling equipment was decontaminated in the field

between each use.

3.2 Groundwater Sample Collection & Analyses

Groundwater was encountered from three (3) to ten (10) feet below grade during the

advancement of the Geoprobe borings and confirmed by measuring the groundwater

level of existing monitoring wells. Existing groundwater monitoring wells located adjacent

to the USTs were sampled to evaluate groundwater quality at the Site. Three (3)

groundwater samples were collected from the existing monitoring well utilizing low-flow

sampling techniques. The groundwater samples were collected by inserting polyethylene

tubing into each well and the groundwater sample was drawn through the tubing using a

low-flow peristaltic pump.

The groundwater samples were submitted for laboratory analysis for VOCs (EPA Method

8260), SVOCs (EPA Method 8270), ETPH (CT-ETPH Method), and Total and Dissolved

RCRA 8 metals. The groundwater samples collected for Dissolved RCRA metals were

field filtered using a 0.45-µm membrane filter prior to acidification. The groundwater

samples were placed in laboratory-supplied glassware and stored in an ice-filled cooler.

3.3 Project Quality Assurance/Quality Control Practices

The DEEP’s Quality Assurance and Quality Control (QA/QC) Guidance was used to

ensure that the analytical results generated during the investigation are of known and

appropriate quality. Specifically, the Laboratory Quality Assurance Control Reasonable

Confidence Protocols (RCPs) was utilized for all laboratory analytical methods. The

Laboratory Quality Assurance and Quality Control, Data Quality Assessment and Data

Usability Evaluation (DQA/DUE) Guidance was utilized to ensure that the analytical data

used is of known and sufficient level of quality for the intended purpose.

To assess the collection of samples in the field in terms of the sampling techniques and

decontamination procedures followed, quality control and quality assurance samples were

collected and analyzed.

Diversified Technology Consultants, Inc. July 2019 Task 210 – Subsurface Site Investigation Wolcott Maintenance Facility Tank Replacement State Project No. 0171-0428, Assignment No. 218-5996 6

Laboratory prepared trip blanks (soil and groundwater) accompanied the samples

obtained during field sampling activities. The soil trip blanks consisted of one (1) methanol

and two (2) de-ionized 40 ml vials. The groundwater trip blank consisted of two (2), 40 ml

vials containing laboratory grade de-ionized water. The trip blanks were placed in the

sample cooler with the daily samples until delivery to the laboratory for analysis of EPA

Method 8260 volatile organic compounds. The data from the trip and field blanks was

included in the laboratory report and was used to assess the effectiveness of the

decontamination procedures used in the field. Data that may have resulted from cross-

contamination due to poor field decontamination and sample storage practices was

qualified so that data users are aware of the potential origins of the contaminants.

All samples collected in the field were stored in a manner that preserves the integrity of

the sample chemistry. Samples intended for organic analyses were stored in an ice-filled

cooler until delivery to the laboratory. Chain-of-Custody (COC) forms were filled out and

accompanied all the samples collected as a legal record of possession of the samples.

The COC is initiated in the field and accompanies the containers during sample collection,

transportation to the lab, analysis, and final disposal of the samples.

All sampling equipment was either dedicated to a specific sample or was decontaminated

prior to and between each use. Sampling equipment were not placed near solvents,

gasoline, or other materials that may impact the integrity of the sampler.

4.0 REGULATORY CRITERIA

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

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

Regulations of Connecticut State Agencies (RCSA), revised June 27, 2013.

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

soil and groundwater, specific numeric cleanup criteria, and processes for establishing

alternative site-specific standards. The RSRs apply to any action which is required pursuant to

Chapters 445, 446k, or Section 22a-208a(c)(2) of the General Statutes, including but not limited

to any such action required to be taken or verified by a licensed environmental professional. The

Regulations also outline the processes for establishing alternative site-specific numerical

standards for certain sites and criterion for additional polluting substances not specified in the

RSRs, upon approval from DEEP. The RSR criteria are based on the property usage

(industrial/commercial or residential) and the DEEP groundwater quality designation (“GA” or

“GB”). Based on our review of the state groundwater quality maps, the Site is located in an area

designated as “GA” quality groundwater, therefore the more stringent criteria apply.

The numeric criteria in the RSRs was utilized as guidelines to evaluate the data and to make

conclusions regarding concentrations of regulated compounds detected in soil and groundwater.

The following summarizes the soil and groundwater criteria utilized during this Task 210 SSIR.

4.1 Soil Criteria

The RSRs contain two sets of soil criteria; the Direct Exposure Criteria (DEC) and the

Pollutant Mobility Criteria (PMC), as summarized below.

Direct Exposure Criteria

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

pollutants in contaminated soil within fifteen (15 feet) of the ground surface. Different DEC

apply to a property depending on land use, either “residential” or “industrial/commercial”,

as defined by the RSRs.

Page 11: Diversified Technology Consultants, Inc. July 2019...Diversified Technology Consultants, Inc. July 2019 Task 210 – Subsurface Site Investigation Wolcott Maintenance Facility Tank

Diversified Technology Consultants, Inc. July 2019 Task 210 – Subsurface Site Investigation Wolcott Maintenance Facility Tank Replacement State Project No. 0171-0428, Assignment No. 218-5996 8

The less stringent Industrial/Commercial (IDEC) cannot be used unless an Environmental

Land Use Restriction (ELUR) has been recorded on the property deed restricting the site to

industrial/commercial uses.

The DEC for substances other than PCBs do not apply to “inaccessible” soil at a release

area provided that such soil is less than 15-feet from the ground surface and

Environmental Land Use Restriction (ELUR) is in effect with respect to the subject parcel

or to the portion of such parcel containing such release area.

The DEC do not apply to metals, petroleum hydrocarbons or semi-volatile substances in

soil provided such pollution is the results of an incidental release due to the normal

operation of motor vehicles, not including refueling, repair or maintenance of a motor

vehicle; or normal paving maintenance of a consolidated bituminous concrete surface

provided such bituminous concrete surface has been maintained for its intended purpose.

Pollutant Mobility Criteria

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

potential for migration of pollutants to the groundwater from contaminated soil. Different

PMC apply to a property depending on the groundwater quality at the site, as designated

by DEEP. In a “GA” groundwater classification area the PMC apply to soil located above

the seasonal low water table and in a “GB” groundwater classification area the PMC apply

to soil located above the seasonal high-water table. The PMC do not apply to

“environmentally isolated” soil at a release area provided that an Environmental Land Use

Restriction (ELUR) is in effect with respect to the subject parcel or to the portion of such

parcel containing such release area. The PMC do not apply to polluted fill on a parcel if

the fill meets the requirements of section 22a-133k-2(c)(4)(B)(i) through (vi). The PMC do

not apply to substances, other than volatile substances, in soil at a release area provided

the release area meets the requirements of section 22a-133k-2(c)(4)(C)(i) through (v).

The PMC do not apply to metals, petroleum hydrocarbons or semi-volatile substances in

soil provided such pollution is the result of: an incidental release due to normal operation of

motor vehicles, not including refueling, repair or maintenance of a motor vehicle; or normal

paving and maintenance of a consolidated bituminous concrete surface provided such

bituminous concrete surface has been maintained for its intended purpose.

Page 12: Diversified Technology Consultants, Inc. July 2019...Diversified Technology Consultants, Inc. July 2019 Task 210 – Subsurface Site Investigation Wolcott Maintenance Facility Tank

Diversified Technology Consultants, Inc. July 2019 Task 210 – Subsurface Site Investigation Wolcott Maintenance Facility Tank Replacement State Project No. 0171-0428, Assignment No. 218-5996 9

Since the site is located in a “GA” groundwater quality area, the GA PMC was used for

comparison to the analytical results. Groundwater was not encountered at the soil boring

locations. However, the depth to water from the existing groundwater monitoring was

measured at 24 feet below grade.

4.2 Groundwater Criteria

Under the DEEP RSRs contaminants in the groundwater are compared either to

background quality or the Ground Water Protection Criteria (GWPC), the Volatilization

Criteria (VC), as well as the Surface Water Protection Criteria (SWPC). However, CTDOT

has had numerous discussions with DEEP staff with regard to groundwater encountered

during “Construction Projects” and the applicability of the RSRs to these situations. Based

on the guidance provided by DEEP, groundwater samples collected are to be compared to

the effluent limits for the “General Permit for the Discharge of Groundwater Remediation

Wastewater” to determine if Groundwater Areas of Environmental Concern (GW-AOECs)

for construction dewatering exist within the project limits that would require special

handling.

6.0 DATA QUALITY ANALYSIS / DATA USABILITY EVALUATION

Sixteen (16) soil samples, three (3) groundwater samples, two (2) soil trip blanks, and one (1)

groundwater trip blank were collected as part of this environmental investigation and submitted

to a state-certified analytical laboratory for analyses using the DEEP Reasonable Confidence

Protocols (RCPs) established for VOCs, SVOCs, ETPH, and metals. The samples were

collected to verify the absence or presence and location of subsurface contamination, and to

assess the potential pollutant impacts to be encountered within the project limits during

construction of the proposed intersection improvements.

A data quality assessment and data usability evaluation were performed for the data generated

in accordance with DEEP guidance and noted the following quality control non-conformances.

Copies of the DQA and DUE worksheets are included in Appendix C.

Non-conformances related to Laboratory Control Sample/Laboratory Control Sample Duplicates

(LCS/LCSDs), LCS, LCS/LCSD RPD, Matrix Spike/Matrix Spike Duplicates (MS/MSDs), and

quality control responses do not have a significant bearing on the accuracy and usability of the

data for its intended uses. In all cases the non-conformances had no impact on the data

usability and the data is of sufficient quality and precision for its intended use based on multiple

lines of evidence.

Based on the above findings from the DQA and DUE, the analytical data is of adequate quality

and of sufficient accuracy, precision and sensitivity to confirm contaminant of concern are

present in the soil at detectable concentrations below the DEEP RSRs and within groundwater

at concentrations below the permit effluent limits. Task 310 Plans, Specifications and Estimate

will be required for the removal of the underground storage tanks (USTs), worker health &

safety, and management of controlled (soil and groundwater) materials which may be

encountered during tank removal activities to be included in the Contract Bid Documents.

7.0 CONCLUSIONS AND RECOMMENDATIONS

DTC conducted a Task 210 SSIR within the project limits in support of State Project No.

0171-0428, Wolcott Maintenance Facility Tank Replacement in Wolcott, Connecticut. The

results of the environmental investigation indicated that contaminants of concern (COCs) exist

in soil within the project limits at concentrations below the applicable RSR criteria and within

groundwater at concentrations below the general permit effluent limits. The presence of these

COCs within the project limits may require controlled material management and disposal should

contamination be detected below the USTs during tank removal operations. Dewatering fluids

should be managed in accordance with the DEEP General Permit for Construction Dewatering,

however, should contamination be detected treatment and permitting of the discharge may be

required in accordance with DEEP General Permit for the Discharge of Groundwater

Remediation Wastewater. Pursuant to Section 22a-449(d)-107 of the RCSA, sampling of soil

and groundwater (if encountered in the tank grave) is required for UST closure. In addition,

specifications for the implementation of worker health and safety procedures during construction

should be included in the contract documents. The following summarizes the results of the

Task 210 SSIR:

• The results of the laboratory analyses indicated that soil from borings (B1 and B2)

within the project limits has been impacted with SVOCs above laboratory detection

limits but below the applicable RSR criteria.

• Metals were detected above laboratory detection limits but below the applicable RSR

criteria in soils throughout the project limits.

• Groundwater samples collected from the three (3) existing monitoring well locations,

contained substances at concentrations below both the effluent limits for discharge to

surface water and the POTW discharge limits.

• Based on the results of this Task 210 SSIR and proposed project activities, DTC

recommends that Task 310 – Plans, Specifications, and Estimate be prepared for the

proper management and disposal of contaminated materials that may be excavated,

handled, transported, or disposed during construction activities, DEEP closure

Comments:

Per 1.4.6 of EPA method 8270D, 1,2-Diphenylhydrazine is unstable and readily converts to Azobenzene. Azobenzene is used for the calibration of 1,2-Diphenylhydrazine.

Semi-Volatile Comment:One of the surrogate recoveries was above the upper range due to sample matrix interference. The other surrogates associated with this sample were within QA/QC criteria. No significant bias is suspected.

DATA USABILITY EVALUATION WORKSHEET

Provide a summary statement describing how the analytical data set relied upon is of adequate quaility and of sufficient accuracy, precision, and sensitivity for the

intended purpose.

To verify the absence or presence and location of subsurface contamination, and to assess the

potential pollutant impacts that may be encountered during construction.

Method exceedance for one or more analytes reported. Compounds not detected in samples.

QC sample was not below reporting limit (GCD45781).

One or more analytes in site specific matrix spike recovery is below method criteria.

Compounds not detected in samples. MSD was not reported for LLVOCs (GCD45785).

The results will be used to verify the absence or presence and location of subsurface contamination, and to assess the potential pollutant impact that may be encountered

during construction.

A data quality assessment and data usability evaluation was performed for the data generated in accordance with the DEEP's "Laboratory Quality Assurance and Quality

Control, Data Quality Assessment and Data Usability Evaluation Guidance Document".

Non-conformances related to LCS, LCSD, LCS/LCSD RPD, MS.MSD RPD and QC Recovery responses do not have significant bearings on the accuracy and usability of the

data for the intended purposes. In all cases the non-conformances have no impact to the data usability and the data is considered of sufficient quality and precision using

multiple lines of evidence.

The data indicates that contaminants are present in the soil at low concentrations below the applicable RSR criteria and in groundwater at concentrations below the DEEP

General Permit discharge limits. Task 310 Plans and Specifications will be prepared to address the underground storage tank removal and closure sampling and worker

health & safety during tank removal operations.

Based on the above findings from the DQA and DUE, the analytical data is of adequate and of sufficient accuracy, precision and sensitivity to identify soil and groundwater in

areas requiring special treatment and/or handling during the construction phase of the project.

For each analytical method referenced in the lab report, not all constituents identified in the

method-specific analyte lists presented in the RCP documents.
