Superfund sites are polluted locations in the United States requiring a long-term response to clean up hazardous material contaminations.
Sites include landfills, mines, manufacturing facilities, processing plants where toxic waste has either been improperly managed or dumped.
They were designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980.
