    Stage of Clean-up: Construction Underway

    Conditions at listing (December l982): The Somersworth Sanitary Landfill covers 24 acres in Somersworth, New Hampshire. Originally, the town burned residential, commercial, and industrial wastes on the site. In l950, the dump was converted to a sanitary landfill. Unknown quantities of sludges, solvents, acids, dyes, metals, laboratory or pharmaceutical wastes, and potash were deposed of at this site. Both surface water and ground water are contaminated. On-site monitoring wells detected moderate levels of CARBON TETRACHLORIDE, ethyl BENZENE, TOLUENE, and metals. Leachate was observed at the eastern edge of the site. Status (July l983): EPA recently completed a Remedial Action Master Plan outlining the investigations needed to determine the full extent of cleanup required at the site. EPA and the State are negotiating a Cooperative Agreement for a remedial investigation/feasibility study to determine the type and extent of contamination at the site and identify alternatives for remedial action. At the same time, EPA is completing a search for parties potentially responsible for wastes associated with the site.

    Sources of Contamination:
    • Landfill

  • Threats and Contaminants
    The groundwater is contaminated with VOCS and inorganic chemicals. Sediments were found to contain low levels of ARSENIC, CHROMIUM, and LEAD. The on-site soil is contaminated with VOCS, polycyclic aromatic HYDROCARBONS (PAHS), and HEAVY METALS. Peter's Marsh Brook and Tate's Brook have been shown to contain VOCS and HEAVY METALS including ARSENIC and MERCURY unrelated to the landfill. Peter's Marsh Brook is considered to be the primary receptor of groundwater contamination.  More...
