  • Site Description
    Stage of Clean-up: Study Underway

    Conditions at listing (September 1983): Landfill & Development Co. operates a 2l0-acre landfill in Mount Holly, New Jersey. It is adjacent to Rancocas Creek and surrounded by residential developments. The site, originally a sand and gravel pit, accepts municipal refuse, industrial and commercial solid waste, and treated sewage sludge. It may have accepted hazardous substances in the past. The local health department has documented that monitoring wells and some private wells are contaminated with volatile organic chemicals. In September l977, the State issued an Administrative Order requiring the company to replace the private wells, install a liner at the landfill, and pump and treat contaminated ground water. The pumping, which is currently underway, involves l5 wells downgradient of the landfill. The water from these wells is aerated and sprayed over a 5-acre wooded area on the site. Status (June 1984): The State is involved in an administrative hearing process to force the facility to obtain a new and revised registration.

    Sources of Contamination:
    • Discharge to sewer/surface water
    • Lagoon disposal
    • Landfill

  • Threats and Contaminants
    The two upper aquifers underneath the site are contaminated with various VOCS and HEAVY METALS. Sediments from Rancocas Creek and Smithville Canal contain HEAVY METALS. The majority of local residents are connected to the public water supply; however, nine residences maintain private wells. Of those nine, only one uses well water for drinking on a regular basis; the other eight residents drink bottled water. Although the private wells are not contaminated, there is a potential that pollutants may migrate to them. Rancocas Creek and Smithville Canal are used for recreational activities. Seeps from the landfill have polluted these waters.
