The Montclair/West Orange Radium site is in the towns of Montclair and West Orange in Essex County, New Jersey. The soil at the site is contaminated with radioactive waste materials suspected to have originated from radium processing or utilization facilities located nearby during the early 1900s. Temporary radon ventilation systems and gamma radiation shielding have been installed and maintained by EPA and the State to reduce indoor exposures. The primary contaminant of concern affecting the soil and structures is radium 226 which decays to radon gas. The selected remedial action for the site includes excavation of approximately 41,000 cu yd of highly contaminated soil and an unspecified amount of debris followed by offsite disposal; installation and maintenance of indoor engineering controls at less contaminated properties; environmental monitoring to ensure remedy effectiveness; and continuation of a treatment technology study for future actions. EPA deferred a final continuation of a treatment technology study for future action.
