4. SITE BACKGROUND

The Nike PR-58 & Disaster Training Village Area (DTVA) Formerly Used Defense Site (FUDS) property (Site) is in North Kingstown, Washington County, Rhode Island. The Property, which comprises approximately 44 acres, is bounded by the former Perimeter Road (now a bike path) to the north, Seabee Avenue to the east, Newcomb Road to the west, and Babcock Road to the south. Most of the Property is currently owned by the Quonset Development Corporation (QDC), a special purpose subsidiary of the Rhode Island Economic Development Corporation (RIEDC), except for approximately 1.7 acres in the southwest corner of the Property that was purchased by Chipster, LLC in 2008. The Property is abutted on the North and West by residential areas. The parcel to the east and south of the Property is currently owned by the Navy and was previously occupied by the Davisville Naval Construction Battalion Center (NCBC). QDC has a Lease in Furtherance of Conveyance (Lease No. N62472-98-RP-00035). This parcel will transfer to QDC once there is a Record of Decision (ROD) for the Property and the remedial action has been implemented.

The Property was previously used by the U.S. Navy as a military camp from 1942 until the end of World War II, by the U.S. Army as the Nike Battery PR-58 from 1954 to 1962, by the U.S. Navy as the DVTA from 1964 to 1974, and by Peabody Clean Industries (PCI) for hazardous materials storage and treatment from 1980 to 1983. Historical operations conducted on the Property by these operations resulted in releases of hazardous materials and impacts to environmental media. In addition, multiple releases of contamination have been documented on sites located downgradient and unrelated to the Property. It is likely that plumes from these sites have commingled with the plume that is a result of activities performed on the Property. The various studies conducted on the Property have determined that releases of hazardous substances from Department of Defense (DOD) activities at the Property resulted in impacts to soil, groundwater, surface water, sediment, and soil gas from chlorinated volatile organics (CVOCs). The CVOCs observed in environmental media on the Property were 1,1,2,2-tetrachloroethane (TeCA), tetrachloroethene (PCE), trichloroethene (TCE), and their degradation products: 1,1,2-trichloroethane (TCA); 1,1-dichloroethene (DCE); cis-1,2-DCE; trans-1,2-DCE; and vinyl chloride (VC). Multiple lines of evidence suggest that the CVOCs were released on the Property in the form of dense non-aqueous phase liquid (DNAPL). Investigations indicate that residual DNAPL is still present in the deeper unconsolidated overburden deposits and bedrock fractures in an area approximately 1/3 acre in size beneath the Property, which is referred to as the “Source Area.”

Concentrations of total CVOCs in the Source Area exceed 70,000 µg/L in groundwater and 10,000 µg/kg in soil. A more dilute plume extends outward from the Source Area. In general, the plume increases in size with depth, covering a greater area in bedrock than in the shallow unconsolidated deposits. The plume has migrated the greatest distance in the bedrock to the east and south of the Source Area and to a lesser extent toward the north.

Historical operations on the former Davisville NCBC facility, which abuts the Property on the east and south, also resulted in releases of hazardous materials and impacts to environmental media. Multiple sites on the former NCBC facility, unrelated to the releases at the Property, have been or are engaged in independent environmental investigation and remediation activities. The footprint of the plume extending from the Source Area on the Property overlaps the plumes of similar types of CVOC contamination from Navy operations to the east and south.

The compounds TeCA; PCE; TCE; cis-1,2-DCE; trans-1,2- DCE; 1,1-DCE; 1,1,2-TCA; and VC were all identified above their Maximum Contaminant Levels (MCLs) or risk-based concentrations in the most recently sampled groundwater on the Property. The compounds TeCA and TCE exceeded the MCLs in the aquifer below the undeveloped portion of the land immediately north of the Property. PCE, 1,1,2-TCA, cis-1,2-DCE, and vinyl chloride were detected in one or more pore water samples collected from Hall Creek, and low concentrations of TCE were detected at one location near Davol Pond. Private drinking water wells to the north and northeast of the Property were sampled in 1997, 2006, 2009, and 2013, although the list of wells sampled in each timeframe varied. There were no detections of CVOCs in these wells, with the exception of trace levels (below MCLs) of PCE and 1,1,1-TCA (0.7 µg/L and 1.0 µg/L, respectively) in one well in 1997. Access to resample this well has not been granted in the numerous follow-on efforts. Not all existing residential wells have been sampled because not all residents granted access to USACE for sampling.

VOCs were detected in surface water samples collected from Hall Creek and Davol Ponds between 2008 and 2013, but at concentrations below the regulatory criteria. Sediment quality guidelines were marginally exceeded in the Hall Creek/Davol Ponds system at only one of six locations sampled. TCE was present in this sediment sample at 97.3 µg/kg as compared to the EPA Benchmark of 96.9 µg/kg.

In 1983, PCI performed a cleanup of contaminated soil related to their activities at and near the Property. This process included the excavation and removal of approximately 710 cubic yards of contaminated soils resulting from the oil/water separator constructed and operated by PCI and the disposal of four oil, water, and waste storage tanks. In addition, RIEDC removed a large concrete pad and a damaged wooden structure from the Property from the proximity of the known Source Area. There is little to no data or information related to these demolition and removal actions by RIEDC. From 2004 through 2005, a Steam Enhanced Remediation (SER) pilot study was conducted to assess the feasibility of using SER technology as a remediation alternative in the future. The test removed roughly 323 pounds of contaminant mass and reduced the levels of CVOCs in some of the Source Area wells as it was designed to do; however, it appears to have temporarily mobilized/redistributed DNAPL and increased the levels of CVOCs in some downgradient wells. One area where the plume of CVOC contamination appears to be increasing in concentrations is in the shallow overburden flowing southeast towards Davol Pond and Hall Creek. Because of the borderline risk associated with the data available in the RI as well as the potential increasing concentration migrating towards this groundwater discharge area, there is potential for unacceptable risk in the wetlands and surface waters of Hall Creek.

The Remedial Investigation/Feasibility Study report for the property was completed in 2016 and the proposed plan completed in 2018. The Proposed Plan’s preferred alternative for the property was the UU/UE alternative which includes thermal treatment in the contaminant Source Area, where the highest concentrations of chlorinated volatile organic compounds (CVOCs) are present in the soil, groundwater, and bedrock fractures; and reductive dechlorination in the downgradient groundwater plume(s) of dissolved CVOC contamination. This alternative was chosen because it provides both short and long-term protection of human health and the environment: reduces the TMV of contaminated groundwater through treatment, to the maximum extent practicable; utilizes permanent solutions; and uses land use restrictions to prevent unacceptable exposures during implementation of the remedy until RGs are attained. The Decision Document for the FUDS was completed in June 2019.

The Source Area has been defined as the area of the Site where chlorinated volatile organic compounds (CVOCs), primarily trichloroethene and tetrachloroethane, have been identified at concentrations greater than 10,000 ug/Kg in soil and/or 70,000 ug/L in groundwater.

Investigations indicate that residual DNAPL is still present in the deeper unconsolidated overburden deposits and bedrock fractures in an area approximately 1/3 acre in size beneath the Site. The exact vertical and horizontal extents of the Source Area are not currently well defined with the limited data available. The vertical extent consists of 25-45 feet of unconsolidated deposits underlain by approximately 40 feet of basal glacial till and weathered bedrock and at least 60 feet of competent bedrock with known contamination.

The total depth of the Source Area in the bedrock is not well defined at this time but it appears that the treatment zone will be extend no deeper than 100 feet below ground surface (bgs).
