Superfund Site: W.R. GRACE & CO., INC./WAYNE INTERIM STORAGE SITE (USDOE), WAYNE TOWNSHIP, NJ

Superfund Site Profile

The W.R. Grace & Co./Wayne Interim Storage site is located in Wayne Township, New Jersey. The 6-acre area was used by Rare Earths, Inc. between 1948 and 1957 to extract thorium and rare earth metals from monazite ore. In 1957, a division of W.R. Grace & Co. Inc. acquired the facility and continued to process monazite ore at the site until 1971. Radioactive waste and contaminated building rubble were stored in burial pits on site. In 1974, W.R. Grace closed the facility and decontaminated the site. In 1980, radiological surface contamination was discovered at the processing facility site and on areas west of the plant. After immediate actions to protect human health and the environment, the site’s long-term remedy was put in place. EPA took the site off the Superfund program’s National Priorities List in 2012.
