Disclaimer / Legal Notices   

The Resource Conservation and Recovery Act (RCRA) is the public law that creates the framework for the proper management of hazardous and non-hazardous solid waste. Corrective action is a requirement under RCRA that facilities that treat, store or dispose of hazardous wastes, or did so in the past, investigate and clean up hazardous releases into soil, groundwater, surface water and air. For more information, and for more information on RCRA-specific terms used on this page, please visit EPA’s umbrella RCRA web page or EPA’s RCRA Corrective Action page.

Cleanup Activities

The facility achieved a "Remedy Construction Complete" determination on June 2, 1995. The waste storage area and treatment tank were "clean closed" in accordance with RCRA regulations. Contaminated soils in multiple parts of the property were excavated and disposed of, and a soil vapor extraction system was constructed to address solvent contamination of certain shallow soils.

Cleanup Actions or environmental indicators characterizing the entire facility are shown below. This listing, and all the data on this page, come from EPA’s RCRAInfo and are refreshed nightly to this page. For this table, a blank in the Status column could mean the action either has not occurred or has not been reported in RCRAInfo.

Facility Description

From 1958 to around 1994, this property was used for the manufacture of aircraft components and reactor cores for the U.S. Navy. Operations at this facility included electroplating, fabricated metal product manufacturing, and industrial machinery manufacturing. Hazardous wastes produced included spent halogenated solvents and cyanide plating baths. It formerly operated a greater than 90 day hazardous waste storage container area and a treatment tank unit.

This approximately 38 acre facility is located in a commercial area of Uncasville, CT. According to the US Geological Survey's National Hydrography Dataset, this facility is located in the Thames River-Frontal New London Harbor watershed and the nearest fresh surface water body is located on or immediately adjacent to the property. Geology in this area has been observed to be dominated by granitic gneiss formations.

Institutional and Engineering Controls at this Facility

Institutional and Engineering Controls help ensure human exposure and groundwater migration are under control at a cleanup facility. Where control types have been reported by states and EPA in EPA’s RCRAInfo, they are shown below. Not all control types are needed at all facilities, and some facilities do not require any controls. Where there are blanks, the control types may not be needed, may not be in place, or may not be reported in RCRAInfo.
