  • Site Description
    Stage of Clean-up: Construction Completed

    Conditions at listing (October 1981): Tybouts Corner Landfill, New Castle County, Delaware, is the site of a former sand and gravel operation. From 1969 to 1971, the 50-acre site, which is privately owned, accepted municipal and industrial wastes. Surface water and ground water are contaminated with hazardous organic and inorganic substances. The area is highly dependent on ground water. In 1976, the State issued demand letters to parties responsible for wastes associated with the site and requested that they take measures to remedy the ground water contamination problem. The parties refused to take responsibility. This is the top priority site in Delaware. Status (July 1983): In January 1983, EPA signed a $755,000 Superfund State Contract with Delaware for a remedial investigation to determine the type and extent of contamination at the site and a feasibility study to identify alternatives for remedial action. The work is scheduled to be completed in the second quarter of 1984. The Department of Justice, on behalf of EPA, has brought a Federal civil action seeking injunctive relief against parties responsible for wastes associated with the site.

  • Threats and Contaminants
    The site was ranked on the NPL in 1983 due to a threat of contamination of the regional aquifer, the primary source of water in this region in Delaware. The site also presented a threat to domestic wells in the immediate vicinity. In 1985, EPA installed a water line to supply homes in the vicinity of the site with public water. The contaminants of concern include 1,2-DICHLOROETHANE, VINYL CHLORIDE, BENZENE and various other organic and inorganic chemicals.
