List of Superfund sites in Maine
This is a list of Superfund sites in Maine designated under the Comprehensive Environmental Response, Compensation, and Liability Act environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations. These locations are known as Superfund sites, and are placed on the National Priorities List.
The NPL guides the EPA in "determining which sites warrant further investigation" for environmental remediation. As of November 29, 2010, there were 12 Superfund sites on the National Priorities List in Maine. No additional sites are currently proposed for entry on the list. Three sites have been cleaned up and removed from the list.
