    Stage of Clean-up: Construction Underway

    Jersey Conditions at proposal (October 15, 1984): The Montclair/West Orange RADIUM Site is in two residential neighborhoods in Montclair and West Orange in Essex County, New Jersey. Radioactive material, believed to be radium-processing waste, was used as fill, resulting in unacceptable levels of RADON+ gas and its decay products in a number of private residences. Approximately 50,000 cubic yards of contaminated material are scattered throughout a neighborhood covering about 1.0 square mile. Several years ago, the State started to investigate a radium-processing facility in Orange that had ceased operation in the l920s. The possibility of off-site disposal of processing waste prompted an aerial survey of surrounding areas for gamma radiation. In July l983, the survey identified a number of homes with high levels of RADON+ gas. About 80 people are immediately affected. In December l983, EPA started a major field investigation to define the perimeter of contamination and identify additional problem homes. Using CERCLA emergency funds, EPA installed ventilation systems in affected homes as a temporary corrective measure.  More...

    Sources of Contamination:
    • Dumping - unauthorized

  • Threats and Contaminants
    The soil on the site is contaminated, to varying degrees, with RADIUM. When this material is located in and around a home, it may result in high levels of RADON+ gas and gamma radiation in the home. RADON+ is a decay product of RADIUM and gamma radiation is the energy released during the decay process. People who are exposed to the RADIUM, RADON+, RADON+ decay products and elevated levels of gamma radiation may be at risk. In addition, accidental ingestion of soil may cause adverse health effects.
