The Maywood, New Jersey, Site is located in Bergen County approximately 13 miles northeast of Newark. The site is included on the National Priorities List.

The site consists of the former Maywood Interim Storage Site and various vicinity properties, including property owned by Stepan Company and 88 residential, commercial, and government properties. From 1916 to 1959, rare earth metals and thorium were processed at the Maywood Chemical Works, resulting in contamination of the properties. In 1985, the federal government acquired an 11.7-acre portion of the site to store soils and debris excavated from the vicinity properties until a suitable and permanent storage site became available. Remedial action is scheduled for completion in 2014. At that time, DOE intends to sell or transfer their property for beneficial reuse.
