The Standard Chlorine Chemical Company Superfund Site is a 25-acre site located in the town of Kearny, New Jersey, on an industrialized peninsula along the Hackensack River. Several chemical manufacturing activities took place on the site from the early 1900s to the 1990s, including the production, storage and packaging of moth balls and flakes. EPA added the site to its National Priorities List in September 2007 after samples indicated the release of dioxins, benzenes, naphthalene, PCBs and other semi-volatile or volatile compounds into the Hackensack River and adjacent wetlands.

The site lies in the Hackensack Meadowlands, which EPA and the U.S. Fish and Wildlife Service have identified as a Significant Habitat Complex that may provide habitat for state- or federally-designated threatened or endangered species. Contamination appears to discharge from ground water to the Hackensack, as well as overland runoff, including through a drainage ditch along the southern property line.  Release of hazardous substances to the surrounding ground water has been documented since at least the early 1980s. In the past, contamination came from several sources, including two lagoons located on the eastern portion of the site, tanks and drums that contain dioxin-contaminated asbestos and other pollutants.  The dioxin-contaminated asbestos has been collected and placed in shipping containers waiting for eventual transport, and all remaining tanks have been emptied. Fish consumption warnings (particularly crab) and a health advisory have been issued for the Hackensack River, potentially due in part to contamination from the Standard Chlorine site.  

Prior to placement on the National Priorities List, the New Jersey Department of Environmental Protection (NJDEP) sampled and studied the Standard Chlorine site and other nearby cleanup efforts and implemented interim measures. EPA currently is working with NJDEP to prevent the spread of additional contamination to surrounding areas, particularly the Hackensack River. Parties potentially responsible for contamination at the site and other nearby cleanups include three parties in a group referred to as the Peninsula Restoration Group. Other potentially responsible parties at this site may be identified by EPA in the future.
