    Stage of Clean-up: Construction Completed

    Conditions at listing (December 1982): The Williams Property is an abandoned waste dump covering 5.6 acres in a rural-agricultural region of Swainton, Cape May County, New Jersey. The property is near coastal wetlands and wildlife management areas. Surface water bodies are used for recreation, while aquifers supply water for about 60 percent of the population of Cape May County. The State drilled and sampled monitoring wells on the site. Analysis revealed high concentrations of toxic and highly volatile organics. The shallow Holly Beach Aquifer has been polluted by the dumping, confirmed by records, of about 225 drums of liquid hazardous wastes in 1979. During initial inspections, the State observed heavy organic odors, extensive soil contamination, and damaged vegetation. The State removed about 1,200 cubic yards of contaminated soil and transported it to the Browning-Ferris Industries Landfill in Glen Burnie, Maryland. Status (July 1983): EPA recently completed a Remedial Action Master Plan outlining the investigations needed to determine the full extent of cleanup required at the site. It will guide further actions at the site.

    Sources of Contamination:
    • Dumping - unauthorized

  • Threats and Contaminants
    The site was found to be contaminated with PHTHALATES, a plastics by-product, and VOCS including XYLENE and METHYLENE CHLORIDE. EPA determined that the contaminated soil posed a significant risk to the local resident. As a result, all contaminated soil was excavated and removed. The ground water was found to be contaminated with VOCS and metals. Nearby resident drinking water was impacted by the contaminated ground water, while the contaminant plume continued to migrate toward other wells in the area. People who ingest or come into direct contact with the polluted water may be at risk. In addition, the site is in a rural, agricultural region near coastal wetlands and wildlife management areas that could be subject to contamination from the site runoff.
