The US has numerous polluted sites due to hazardous waste, spanning manufacturing, processing, landfills, and mining. The Environmental Protection Agency (EPA) employs Superfunds to facilitate the cleanup. Responsible parties must either clear the contamination or reimburse the EPA. In cases lacking accountable parties, the EPA handles the cleanup. These sites are considered to pose health and environmental risks, with hazard rankings reflecting potential waste release and its impact. You can view the map of the Superfund sites around the United States on the EPA website.
