The former Davisville U.S. Naval Construction Battalion Center (NCBC) contains 12 areas of contamination (AOCs) and four study areas (SAs). This ROD addresses Site 08-Transformer Oil Disposal Area and Site 05-Defense Property Disposal Office (DPDO) Film Processing Disposal Area.

NCBC Davisville is located in the town of North Kingstown, Rhode Island, approximately 18 miles south of Providence. A significant portion of NCBC Davisville facility is located adjacent to Naragansett Bay. NCBC Davisville is composed of three areas including the Main Center, the West Davisville storage area, and Camp Fogarty, located four miles west of NCBC Davisville.

Site 05 is located in the Main Center of NCBC Davisville. It consists of a relatively flat, overgrown area to the east of Building 37 and adjacent to Camp Avenue. It is located outside the fence line surrounding NCBC Davisville but within Navy property. A north-south ridge consisting of exposed shale bedrock and boulders is located on the eastern side of the site.

Site 05 is located adjacent to an area historically used for storage of materials and equipment awaiting shipment. In 1968 or 1969, approximately 30 gallons of transformer oil containing polychlorinated biphenyls (PCBs) were reportedly disposed of on the ground within an identified 1,500 square foot site area. In October 1984, Navy personnel collected a surface soil sample from the area which indicated the presence of PCBs at six parts per million (ppm). No removal or remedial response actions have been conducted at the site.

Site 08 is a flat, grass covered area to the east of Building 314 at West Davisville. The site, 80 feet by 40 feet in area, was likely to have received runoff from a reported waste disposal area. A ten-foot wide asphalt road passes through the center of the site. A fence delineating the NCBC Davisville property line forms the eastern border of the site and Building 314 forms the western border of the site.

For a six-month period during 1973, the DPDO recovered silver from photographic wastes. This silver recovery operation was operated as a batch system with a 15 to 20 gallon capacity. Waste liquids from this recovery process were reportedly discharged during rainfall events onto the pavement outside of Building 314 and were allowed to drain from the pavement. The waste liquids which were generated consisted of photographic compounds, such as sodium thiosulfate and hydroquinone, and liquids containing small concentrations of formaldehyde, acetic acid, potassium hydroxide and sulfuric acid. No information on the disposal frequency or total discharge was available from interviews or record searches; however, the amounts were reportedly small. No removal or remedial response actions have been conducted at the site.
Remedy:  The selected remedy for the soils operable unit is no further action.
