Superfund Site: MONTCLAIR/WEST ORANGE RADIUM SITE
MONTCLAIR/WEST ORANGE, NJ
Superfund Site Profile
The site is located in Montclair and West Orange, New Jersey. The 120-acre area included 469 residential properties and 10 municipal properties. Soil at the site was contaminated with radioactive waste materials suspected to have originated from nearby radium-processing facilities that operated in the early 1900s. Houses were later built on or near radium waste disposal areas. Some of the radium-contaminated soil was used as fill in the low-lying areas, and some was mixed with cement for sidewalks and foundations. This site is similar to the nearby Glen Ridge Radium Superfund site, which also had radium-contaminated soils from the same sources. Because of their proximity and the similarity of the contamination, EPA addressed the two sites jointly. Following emergency actions to protect human health and the environment, and the completion of the site’s long-term cleanup, EPA took the site off the Superfund program’s National Priorities List in September 2009.
