Record of Decision – Operable Unit 1 [PDF 9.2 MB, 335 pp]

The Maywood Chemical Co. site is located in Maywood, Rochelle Park and Lodi New Jersey, a densely populated residential and commercial area about 10 miles west of New York City. The original Maywood Chemical Works began operations in the late 1890's. Operations from 1916 to 1955 included thorium processing from monazite sands, which resulted in residual radioactive thorium waste. Other processing activities generated various types of chemical wastes. These waste materials were used as fill on the property and at nearby properties.

From 1980 to 1983, testing by the New Jersey Department of Environmental Protection, EPA and the Department of Energy revealed extensive low-level radiological contamination in several locations. These studies were the basis for the site being added to the National Priorities List. Additional testing identified chemical wastes associated with former processing activities in the soil and groundwater.
