  • Site Description
    Stage of Clean-up: Construction Completed

    Conditions at listing (September 1983): The South Municipal Water Supply Well in Peterborough, New Hampshire, serves about 4,600 people. Routine sampling of the water supply by the State detected VOLATILE ORGANIC COMPOUNDS, including 1,1,1-TRICHLOROETHANE, CARBON TETRACHLORIDE, 1,1-DICHLOROETHANE, and TRICHLOROETHYLENE. Similar compounds were detected in adjacent surface waters. Further investigation is needed to identify the source(s) and determine the extent of contaminant migration. Status (June 1984): The State is planning to conduct a limited hydrogeologic investigation at the site during the summer of l984.

    Sources of Contamination:
    • Dumping - unauthorized

  • Threats and Contaminants
    The soils and surface water were contaminated with VOLATILE ORGANIC COMPOUNDS (VOCS) including CHLOROFORM, BENZENE, and TOLUENE. Sediments also were contaminated with VOCS and POLYCHLORINATED BIPHENYLS (PCBS). Groundwater is contaminated with VOCS. People who accidentally ingest or come into direct contact with contaminated groundwater may be at risk. Included within the site area is the Contoocook River/Noone Pond system and a wetlands area that could have been at risk from contamination.
