East Lyme P&FS Region 2 UST Replacement October 2019 Task 210 1

1.0 Introduction

1.1 Overview

Pursuant to TRC’s Connecticut Department of Transportation (ConnDOT) Contract for On-Call Environmental Services, TRC performed a Task 210 Subsurface Site Investigation at the ConnDOT Properties and Facilities (P&FS) facility located at 273 Flanders Road (referred to as the “Site”) in East Lyme, Connecticut (Figure 1). The Site is developed with a main maintenance building, a large salt shed, paved driveways and parking areas, and landscaped areas.

Specifically, this investigation was conducted near the maintenance building where a 2,000-gallon fuel oil underground storage tank (UST) will be decommissioned and replaced with a 4,000-gallon fuel oil aboveground storage tank (AST).

1.2 Objectives

The primary objectives of this Task 210 site investigation were to:

• Determine soil and groundwater quality in the area of the facility’s current 2,000-gallonfuel oil UST;

• Determine the soil quality in the area of the new 4,000-gallon fuel oil AST; and

• Utilize the gathered data to determine how best to manage soil and groundwater duringthe tank removal and replacement activities and whether Plans and Specifications arerequired for the impending construction.

1.3 Background

Based on limited discussions with ConnDOT personnel, ConnDOT is removing one 2,000-gallon fuel oil UST which is currently installed at the East Lyme P&FS Facility. The Site is developed with a main maintenance building, a large salt shed, paved driveways and parking areas, and landscaped areas. The fuel oil UST is located on the northeastern side of the building. The tank location is depicted on Figures 2 and 3. In addition, the new replacement fuel oil AST will also be located to the northeast of the building.

1.4 Geologic/Physical Setting

As indicated by the Surficial Materials Map of Connecticut (Stone et al, 1992), the Site is located in an area underlain by thin till. Surficial materials at this site are characterized by areas of till that are generally less than ten to fifteen feet thick and areas of bedrock outcrops where till is absent. The material is predominantly upper till, loose to moderately compact, generally sandy and commonly stony.

Based on the descriptions of the soil cores collected during the Task 210 field investigation, the Site is generally underlain by silt and fine sand with varying amounts medium to coarse sand and gravel.


As indicated by the Geological Map of Connecticut (Rogers, 1985), the Site is located within the Potter Hill Granite Gneiss Formation, which is characterized by light-pink to gray, medium to coarse-grained, well-foliated granite gneiss. The topography in the immediate project area can be characterized as generally flat, slightly sloping from southeast to northwest toward nearby Latimer Brook. Groundwater generally flows from high topographic points to low topographic points, but can also be heavily influenced by aquifer type, depth to bedrock, nearby watercourses, groundwater use (withdrawal wells) and subsurface structures. Based on the local topography and features, groundwater is anticipated to flow to the northwest. During the investigation, groundwater was observed at 8.5 feet below grade (ftbg). According to the Connecticut Department of Energy and Environmental Protection (CTDEEP) groundwater classification maps reviewed by TRC, groundwater beneath the Site is classified as “GA”. GA groundwater designated uses are existing private and potential public or private supplies of water suitable for drinking without treatment. The southwestern portion of the site is located in a Final Aquifer Protection Area (Level A).


2.0 Technical Approach This section of the report summarizes the soil and groundwater sampling methods employed during the Task 210 field investigation. Observations made in the field are also summarized in this section. The Task 210 work performed at this Site was completed in accordance with the TRC Work Request for Task 210 Subsurface Site Investigation: East Lyme P&FS Region 2, East Lyme CT, prepared by TRC in August 2019. Any exceptions to the proposed plan are noted in the following sub-sections. As indicated above, the focus of the Task 210 Subsurface Site Investigation was to characterize soil and groundwater at the Site in the areas of the existing UST and future AST. Four soil borings were advanced around the concrete pad that covers the 2,000-gallon fuel oil UST. One shallow soil boring was advanced in the vicinity of the future 4,000-gallon fuel oil AST. A total of seven soil samples (including one duplicate sample) were collected from the five soil borings for submission to the laboratory for analysis (one to two samples per boring). In addition, one grab groundwater sample was collected from soil borings ELMF-SB03 (advanced southeast of the heating fuel oil UST. The grab groundwater sample was collected by installing a temporary one-inch polyvinyl chloride (PVC) well point in the boring. The seven soil samples and one grab groundwater sample were submitted to the laboratory for the following analyses:

• Volatile Organic Compounds (VOCs) by EPA Method 8260 (with Method 5035 field preservation for the soil samples);

• Semi-Volatile Organic Compounds (SVOCs) by EPA Method 8270; • Extractable Total Petroleum Hydrocarbons (ETPH) by Connecticut Department of

Public Health Method; and • Total RCRA 8 metals by EPA Methods 6010/7471.

All samples were analyzed by Phoenix Environmental Laboratories (Phoenix) of Manchester, Connecticut in accordance with Connecticut’s Reasonable Confidence Protocols (RCPs). 2.1 Preliminary Activities Prior to beginning the investigation, TRC marked the proposed boring locations at the Site with white paint on the ground surface. “Call Before You Dig” (CBYD) was contacted to mark the locations of buried utilities in the proposed work zones. In addition, a private utility locating service (Underground Surveying of Brookfield, CT) was contracted to conduct a more detailed screening given the presence of several utilities within the work areas. Preliminary activities also included the preparation of a Health and Safety Plan (HASP) to address the field work to be completed as part of this Task 210.


2.2 Soil Boring Program Methodology A total of five soil borings were advanced on August 12, 2019 by Cisco Geotechnical, LLC (Cisco) under the direct supervision of TRC personnel. These borings were advanced utilizing a tracked GeoProbe™ direct-push drill rig. Soil cores were collected continuously from the ground surface to depths ranging from five to 10.5 ftbg. Each five-foot soil core, collected in an acetate Macro-Core® liner, was logged with respect to soil characteristics (i.e., grain size, moisture content and any other physical characteristics) and indications of potential impacts (e.g., stains and odors). In addition, each core was field-screened using a photoionization detector (PID) prior to the collection of soil samples for analysis. Soil boring logs are presented in Appendix A. The soil boring/sampling locations are shown on Figure 3. The initial criteria for selecting a sample interval for laboratory analysis were visual and olfactory observations and/or PID screening results. In the absence of obvious evidence of impacts in the soil borings advanced around the UST, the soil sample intervals were chosen based on the most-likely interval for impacts, that typically being a depth corresponding with bottom of the tank and/or directly at or above the groundwater interface. TRC presumes the tank is from six feet in diameter with three to four feet of cover material, and groundwater was observed at 8.5 ftbg. Therefore, the bottom of the tank (estimated at nine to ten ftbg) and the observed water table depths are in close proximity to one another. Soil samples submitted to the laboratory for VOC analysis were collected in accordance with EPA Method 5035. This method outlines the collection of soil samples, without homogenization and with minimal disturbance, and transfer into extraction solvents. The remaining soil was then homogenized and placed in the appropriate laboratory-supplied sample containers and then placed in a cooler with ice, for delivery to the laboratory. The excess soils and drill cuttings were returned to their respective boreholes. Final borehole locations were documented by measuring from two or more fixed locations and recording those measurements in the project field notebook. The probe tip and Macro-Core® sampler were decontaminated between uses to minimize the potential for cross-contamination. The decontamination was completed by washing with an Alconox and tap water mixture, followed by a tap water rinse and a final deionized water rinse. Field Observations Based on the descriptions of the soil cores, the Site is primarily underlain by light to medium brown silt and fine sand with varying amounts of medium to coarse sand and gravel. Each soil core was screened with a PID for volatile organic vapors. No odors, staining or PID measurements were observed in any of the soils recovered from the borings. Drilling refusal was encountered in four of the five soil borings: ELMF-SB01 at a depth of seven ftbg, ELMF-SB02 at a depth of six ftbg, ELMF-SB03 at a depth of 10.5 ftbg, and ELMF-SB04 at a depth of 8.5 ftbg.


2.3 Groundwater Sampling Program Methodology TRC directed Cisco to insert a temporary well point consisting of one-inch diameter PVC screen (10-slot or 0.01-inch openings) and solid PVC risers into borehole ELMF-SB03. The screened section was set at a depth interval in the borehole that intersected the water table. The formation was allowed to collapse around the screen and riser. Groundwater and fines were evacuated from the temporary well prior to sampling using a peristaltic pump with dedicated silicon and polyethylene tubing. The grab groundwater sample was collected directly into the appropriate laboratory-supplied containers and placed in a cooler with ice for shipment to the laboratory under proper chain-of-custody procedures. Field Observations The scope of work called for the installation of a temporary well point in the vicinity of the 2,000-gallon UST. A temporary well point was installed to the southeast of the UST in boring ELMF-SB03 with a screened interval from 5.5 ftbg to 10.5 ftbg. A grab groundwater sample was collected from the temporary well point and submitted for analysis. The groundwater sample collected from the temporary well point exhibited a slightly silty appearance. No sheens were noted on the purge water from the temporary well point nor were any odors detected. 2.4 Quality Assurance/Quality Control Samples Quality assurance/quality control (QA/QC) samples were collected as part of the Task 210 subsurface investigation. In order to determine the effectiveness of the decontamination of the sampling equipment, a field equipment rinsate blank was collected and analyzed for the same analyses as the primary samples submitted on the day of the sampling. The field equipment rinsate blank was collected by pouring laboratory-supplied de-ionized water over and/or through the sampling equipment (acetate liner, sampling tubing, etc.) used in the collection of the samples. The rinsate water was then collected into the appropriate laboratory-supplied sample containers. The field rinsate blank associated with this sampling program was designated as “FB20190812”. A groundwater trip blank was provided by Phoenix Laboratories and was submitted for analysis for VOCs by EPA Method 8260 as part of the sampling regimen. The sample was identified as “TB20190812”. In addition, solvent blanks were submitted to evaluate the effect of sample storage and shipment on sample integrity for the soil samples collected for VOC analysis. Furthermore, solvent blanks are used to ensure that proper sample container preparation and handling procedures were utilized following EPA 5035 Method protocols for field preservation of VOC soil samples. Vials of methanol and de-ionized water to be used for VOC soil sampling were prepared by the laboratory. The solvent blanks associated with this soil sampling program were designated as “SB20190812-LL” and “SB-High”. Duplicate samples are two separate samples collected from the same source. The procedure for collecting a duplicate sample consists of alternating the collection of the sample between the


primary sample container and the duplicate sample container. The duplicate soil sample collected as part of this soil sampling program was labeled as ELMF-SB30(8-10), a duplicate of soil sample ELMF-SB03(8-10).


3.0 Investigation Results The following section provides a summary of the analytical results for the soil and grab groundwater sampling conducted at the Site. Seven soil samples (including one duplicate soil sample) and one grab groundwater sample were collected and analyzed for VOCs, SVOCs, ETPH, and total RCRA 8 metals. The soil analytical results are summarized in Table 1 and the groundwater analytical results are summarized in Table 2. A copy of the laboratory report is provided in Appendix B. Although the project site is not subject to the Transfer Act, the Voluntary Cleanup Program, nor the requirements of a Consent Order, the soil and groundwater analytical results were compared to the Connecticut Remediation Standard Regulations (RSRs) to evaluate the levels of any detected contaminants within the investigated areas. This allows for management of any contaminated media encountered during the impending construction activities in a manner consistent with applicable regulations. The reported concentrations for soils were compared to the Residential Direct Exposure Criteria (RES DEC) and the GA Pollutant Mobility Criteria (GA PMC) under the RSRs. The Industrial/Commercial (I/C) Criteria are not technically applicable at a site unless an Environmental Land Use Restriction (ELUR) is implemented, therefore, those criteria are not presented herein. The analytical results of the grab groundwater sample were compared to the Groundwater Protection Criteria (GWPC), Surface Water Protection Criteria (SWPC) and the Residential Groundwater Volatilization Criteria (RES GWVC). 3.1 Soil Sample Results As indicated above, a summary of the soil sample analytical results is presented in Table 1. A copy of the laboratory analytical report for soil samples is included in Appendix B. VOCs No VOCs were detected at concentrations above the laboratory reporting limits in any of the soil samples collected as part of this investigation. SVOCs No SVOCs were detected at concentrations above the laboratory reporting limits in any of the soil samples collected as part of this investigation. ETPH ETPH was not detected above laboratory reporting limits in any of the soil samples collected as part of this investigation.


Total RCRA 8 Metals The metals arsenic, barium, chromium and lead were detected above the laboratory reporting limits in each of the seven soil samples. The reported concentration of arsenic in soil sample ELMF-SB03(2-4) exceeded the RES DEC with a concentration of 19.8 mg/kg. The reported concentrations in the remaining soil samples were below their applicable RSR criteria. 3.2 Groundwater Sample Results As indicated above, a summary of the groundwater sample analytical results is presented in Table 2. A copy of the laboratory analytical report for the groundwater sample is included in Appendix B. VOCs No VOCs were detected at concentrations above the laboratory reporting limits in the grab groundwater sample collected as part of this investigation. SVOCs No SVOCs were detected at concentrations above the laboratory reporting limits in the grab groundwater sample collected as part of this investigation. ETPH ETPH was not detected at a concentration above the laboratory reporting limits in the grab groundwater sample collected as part of this investigation. Total RCRA 8 Metals The metals barium and chromium were detected at concentrations above the laboratory reporting limits in the grab groundwater sample. The reported concentrations of these metals in ELMF-SB03-GW did not exceed any of the applicable RSR criteria. 3.3 Quality Assurance / Quality Control Sample Results As indicated in Section 2.4, the field equipment rinsate blank, trip blank, solvent blanks, and duplicate soil samples were submitted to the laboratory as part of the sampling program for QA/QC purposes. The field rinsate blank did not exhibit detectable concentrations of any constituents. Overall, the results are indicative that the field equipment used for the sampling had been adequately decontaminated and had no adverse impact on the soil or grab groundwater analytical results. The concentration of detected metals in the duplicate samples varied slightly from those detected in the primary samples. The minimal variation in the reported metal concentrations indicates that the samples were adequately homogenized in the field and the laboratory’s processing of the samples was consistent. VOCs were not detected in the groundwater trip blank or soil solvent blanks associated with this investigation.


4.0 Conclusions and Recommendations This section briefly summarizes the findings of the Task 210 exploratory site investigation activities conducted at the site on August 12, 2019. Also included are recommendations based on these findings/conclusions. 4.1 Soil

a. The soil borings drilled in the planned UST removal area were advanced to a maximum depth of 10.5 ftbg. In general, the site is primarily underlain by brown fine-grained sands and silt with varying amounts of fine to coarse sand and gravel. No field evidence of contamination (i.e., elevated PID measurements, odors and/or staining) were observed in any of the soil borings.

b. No VOCs, SVOCs, or ETPH were detected in any of the soil samples collected as part

of this investigation. c. Low levels of the metals arsenic, barium, chromium and lead were detected in each of

the soil samples at concentrations below the RSR criteria, except for ELMF-SB03(2-4), which had an arsenic concentration that exceeded the RES DEC. Given the similar concentrations of each metal in the soil samples, these results likely represent background conditions.

Recommendation Based on the results of this investigation, TRC recommends that appropriate Plans, Specifications, and Estimates (Task 310) be prepared. It is recommended that a Notice To Contractor be prepared to notify the tank replacement contractor of the results of the investigation and presence of arsenic impacted materials immediately around the tanks to be removed. In addition, controlled materials handling and health and safety specifications are warranted. 4.2 Groundwater

a. Groundwater was encountered within the project area at approximately 8.5 ftbg near the heating fuel oil UST.

b. The groundwater sample identified as ELMF-SB03-GW was collected from temporary

1-inch PVC well point installed in the boring.

c. No VOCs, SVOCs, or ETPH were detected in the grab groundwater sample collected during this investigation.

The metals barium and chromium were detected in the grab groundwater sample at reported concentrations below their respective criteria. The detected concentrations of metals seen in the sample may be a result of turbidity of the grab groundwater sample.


Recommendation: The UST most likely measures six feet in diameter, with three to four feet of cover. The depth to bottom of the USTs would then be approximately nine to ten ftbg. Although the observed depth to groundwater of 8.5 ftbg at the site, it is unlikely that dewatering will be required for its removal. Based on the results of this investigation, TRC recommends that a Notice To Contractor be prepared to notify the tank replacement contractor of the investigation groundwater results.

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.


3 = This parameter exceeds laboratory specified limits.
