  • Site Description
    Stage of Clean-up: Construction Completed

    Conditions at listing (September 1983): The Ewan Property is a 43-acre, privately-owned property located in Shamong Township, Burlington County, New Jersey. An estimated 400 to 500 drums of hazardous waste containing various solvents, HEAVY METALS, and POLYNUCLEAR AROMATIC HYDROCARBONS have been buried on an approximately 4-acre section of the property. The State has detected those chemicals in the aquifer currently supplying drinking water to about 1,000 area residents. Single-family residences are located as close as 2,000 feet away. Status (June 1984): EPA is conducting a search for parties potentially responsible for wastes associated with the site.

    Sources of Contamination:
    • Dumping - unauthorized
    • Storage - drums/containers of waste

  • Threats and Contaminants
    Monitoring wells indicate that the Site includes a contaminated groundwater plume containing VOCS including ACETONE, XYLENE, and BENZENE and the HEAVY METALS ARSENIC, CHROMIUM and ALUMINUM. To date, contaminants have not been detected in off-Site residential wells. Two aquifers below the Site are hydraulically linked. Local groundwater flows in a southerly direction. Site soils are contaminated with VOCS and HEAVY METALS. EPA has determined that drinking contaminated groundwater could pose a public health threat. Site groundwater also poses a threat to the New Jersey Pinelands which is a sensitive ecosystem and major groundwater recharge area.
