Superfund Site Profile
The Glen Ridge Radium site is located in the towns of Glen Ridge, Bloomfield and East Orange, New Jersey. The 130-acre area includes 430 residential properties and 14 municipal properties. Soil at the site was contaminated with radioactive waste materials suspected to have come from nearby radium-processing facilities that operated in the early 1900s. Later, houses were built on or near radium waste disposal areas. Some of the radium-contaminated soil was used as fill in low-lying areas. Some was mixed with cement for sidewalks and foundations. The site is similar to the Montclair/West Orange Radium site, which also had radium-contaminated soils from the same sources. Because of their proximity and the similarity of the contamination, EPA has jointly addressed the two sites. Following emergency actions to protect human health and the environment, long-term cleanup work began in 1990. All cleanup and restoration activities finished in December 2004. EPA took the site off the Superfund program’s National Priorities List in September 2009.
