Congress enacted the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund and codified as 42 U.S.C. 9601 et seq., on December 11, 1980. CERCLA was amended by the Superfund Amendments and Reauthorization Act (SARA) on October 17, 1986.
CERCLA gave the Federal government the authority and the funding (i.e., Superfund) to clean up sites contaminated by hazardous waste. The EPA administers Superfund and provides an overview of CERCLA.
