  • Site Description
    Stage of Clean-up: Construction Completed

    Conditions at proposal (October 15, 1984): The Brunswick Naval Air Station, in Brunswick, Sagadahoc County, Maine, encompasses seven areas that were used in the past (beginning in 1942) for the storage or disposal of hazardous wastes. These areas are within a 2-mile radius and occupy a total of at least 15 acres. Of the seven areas, two were used for landfilling the station's household and office wastes. The other areas were used for disposal of acid, caustic, and ASBESTOS wastes. Pesticides, solvents, and waste oils present on the site threaten ground water (including a nearby public well field serving 18,000 people), surface water, and adjacent wetlands. The Brunswick Naval Air Station is participating in the Installation Restoration Program, established in 1978. Under this program, the Department of Defense seeks to identify, investigate, and clean up contamination from hazardous materials. The Navy has identified the potential threats to human health or the environment caused by past practices at the seven areas, and in 1984 will start a study to further identify the contaminants present at the site and determine their migration paths. EPA intends to monitor future work at Brunswick and provide technical assistance to the Navy as needed. Status (July 22, 1987): The Navy completed the Site Verification Stage of the Installation Restoration Program, which is the first phase of a multiphase program.  More...

  • Threats and Contaminants
    Due to past disposal practices, the soil and groundwater on a portion of the base is contaminated with VOLATILE ORGANIC COMPOUNDS (VOCS). Harpswell Cove, a valuable, commercial fishery located downgradient of the site, is subject to potential groundwater contamination. Ingestion of contaminated groundwater may pose health risks, however it has been determined though investigations that no current drinking water supplies are threatened.
