Superfund Site: MAYWOOD CHEMICAL CO., MAYWOOD/ROCHELLE PARK, NJ
Superfund Site Profile
The Maywood Chemical Superfund Site is located on more than 90 properties in Maywood, Lodi and Rochelle Park, Bergen County, about 10 miles west of New York City. From 1916 through 1955, the Maywood Chemical Works processed radioactive thorium ore on site, which resulted in residual radioactive thorium waste. Other processing activities generated various types of chemical wastes. These waste materials were used as fill on site and at nearby properties, resulting in chemical and radioactive contamination over much of the local area.
The site is being cleaned up by two separate entities – the federal government’s U.S. Army Corps of Engineers (USACE) and Stepan Company, a responsible party. The USACE is responsible for radioactive contamination and all contamination on or emanating from an 11.7 acre government-owned property, which is known as the Maywood Interim Storage Site (MISS). The USACE cleanup work is funded by continuing Congressional appropriations under the Formerly Utilized Sites Remedial Action Program (FUSRAP). Stepan is responsible for non-FUSRAP contamination on or emanating from former Maywood Chemical Works properties. Radiological soil cleanup work is underway and additional remedies for groundwater and chemically-contaminated soil are in development.
