List of Superfund sites in Arizona


This is a list of Superfund sites in Arizona 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 May 1, 2010, there were nine Superfund sites on the National Priorities List in Arizona. Three other sites have been cleaned up and removed from it; no sites are currently proposed for addition to the NPL.
