    Stage of Clean-up: Design Underway

    Conditions at listing (September 1983): Radiation Technology, Inc., manufactures plastics on a l5-acre site close to Lake Denmark in Rockaway Township, Morris County, New Jersey. The area is totally dependent upon ground water for drinking supplies. Analyses by the State indicate that ground water is contaminated by plasticizers and chlorinated solvents, which were released through dumping of wastes or burial of drums. These pollutants also pose a threat to nearby streams and Lake Denmark. Two on-site wells were condemned by the local health department in March l98l, and the State issued directives of various types in l98l instructing the company to remedy the situation. When the company did not comply, the State filed a Verified Complaint and Order to Show Cause in March l982. On July 7, 1983, the State issued a Consent Order requiring the company to monitor ground water to determine the source of contamination. Status (June 1984): The monitoring program continues.

    Sources of Contamination:
    • Discharge to sewer/surface water
    • Dumping - unauthorized
    • Explosive disposal/detonation
    • Lagoon disposal
    • Lake or river - disposal in
    • Landfill
    • Manufacturing process
    • Storage - drums/containers of waste
    • Underground injection

  • Threats and Contaminants
    Groundwater has been contaminated with VOCS including BENZENE, CARBON TETRACHLORIDE, and TRICHLOROETHYLENE (TCE). A surface water stream connected to Lake Denmark was also found to be contaminated with VOCS. Lake Denmark and its aquatic life may be threatened from groundwater and surface water VOC contamination. Potential health risks may exist for individuals who drink contaminated groundwater or come into direct contact with the contaminated waters.
