Funds to restore a polluted industrial site may be allocated through the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as the Superfund. This law provides a framework for cleanup of sites contaminated with hazardous substances, including industrial pollutants like PCBs. The Superfund is overseen by the Environmental Protection Agency (EPA) in the United States, but other countries may have similar laws and agencies to address contaminated sites.
