Sources of Contamination

Decades of industrial use contributed to the contamination of the Gowanus Canal. The Environmental Protection Agency (EPA)‘s Remedial Investigation (RI) identified waste from tanneries, factories, and chemical plants that freely flowed into the canal. A key feature of the EPA’s Superfund process is the “enforcement first” policy, which identifies Potentially Responsible Parties (PRPs) for contamination. The map shown below identifies the parties that have received general notice letters from the EPA informing them that they are a responsible party and that they share responsibility for the entire canal.
