Redevelopment at the Site

The 120-acre Montclair/West Orange Radium Superfund site is located in Essex County, New Jersey. The site area included 469 residential and 10 municipal properties. In the early 1900s, radium processors disposed of waste materials on undeveloped land at the site. These activities resulted in widespread radioactive soil contamination. In the 1920s, residential developers used contaminated materials to fill in low-lying areas and they built many homes on the contaminated fill. In a few instances, developers mixed contaminated materials into cement for sidewalks and foundations. In 1983, the State of New Jersey identified a number of homes on the site with high levels of radon, as well as indoor and outdoor gamma radiation. EPA placed the site on the Superfund program’s National Priorities List (NPL) in 1985. Cleanup activities that began in 1990 included removal and disposal of radium-contaminated soil. Afterwards, workers restored properties. Cleanup work ended in 2004 and EPA deleted the site from the NPL in 2009. The successful cleanup of the site allowed the continued use of several municipal parks and streets and allowed hundreds of residents to remain in their homes.
