 The United Heckathorn Superfund Site is located in the Richmond Harbor and includes five acres of land and about 15 acres of marine sediments in the Lauritzen and Parr Channels. Contaminants from the activities of several companies that formulated, packaged, and shipped pesticides at this location from the mid-1940s to mid-1960s persist on this site. In March 1990, the United Heckathorn site was listed on the Federal Superfund List and the EPA directed cleanup efforts including dredging and capping upland areas.

Dichlorodiphenyl trichloroethane (DDT) and dieldrin have persisted despite the large-scale cleanup. Current EPA studies show that DDT and dieldrin levels in the sediment, mussel, and fish are above cleanup levels in the Lauritzen Channel and DDT-contaminated sediment appears to be redistributed within the channel above cleanup levels. In response to increased contamination levels, the City of Richmond has been working with EPA since January 2012 on the United Heckathorn cleanup plan and community engagement strategy.
