    Stage of Clean-up: Design Underway

    Conditions at proposal (September 18, 1985): Standard CHLORINE of Delaware, Inc., manufactures chlorinated benzenes on a 46-acre site in Delaware City, New Castle County, Delaware. In September l98l, about 5,000 gallons of MONOCHLOROBENZENE spilled from a railroad tanker car onto the Standard CHLORINE property. Subsequent testing by the company and the State has detected chlorobenzenes in on-site soils, ground water underlying the site, and Red Lion Creek, which is about 1,000 feet north of the site. Ground water within 3 miles of the site supplies private and public wells serving an estimated 152,000 people. Standard CHLORINE has retained a consultant to study the site and recommend remedial alternatives. Status (July 22, 1987): EPA's preliminary plan for fiscal year 1987 includes a remedial investigation/feasibility study (RI/FS) to determine the type and extent of contamination at the site and identify alternatives for remedial action. The State is negotiating with Standard CHLORINE to conduct the RI/FS.

    Sources of Contamination:
    • Discharge to sewer/surface water
    • Inadvertent spill
    • Waste pile

  • Threats and Contaminants
    Chlorobenzenes from spilled material have been found in the ground water, soil, sediments, and surface water. People may be exposed to the chemicals by direct contact with contaminated soil or accidentally ingesting contaminated soil or water. Wetlands near the site are threatened by contamination emanating from the spill areas. The levels of contamination in the soils, surface water, and sediment may impact the quality of the wildlife and the ecosystems along the Red Lion Creek. Chlorobenzenes have been found in tissue of fish obtained from Red Lion Creek.
