List of Superfund sites in Washington (state)

Image:Superfund sites in Washington.svg

This is a list of Superfund sites in Washington State designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.P.L. 96-510, {{USC|42|9601|9675}}), December 11, 1980.

These locations are known as Superfund sites, and are placed on the National Priorities List (NPL). The NPL guides the EPA in "determining which sites warrant further investigation" for environmental remediation. As of May 1, 2010, there were 48 Superfund sites on the National Priorities List in Washington.{{cite web| url=http://www.epa.gov/superfund/sites/npl/ |title=National Priorities List |publisher=United States Environmental Protection Agency |access-date=May 1, 2010}} Seventeen others have been cleaned up and removed from the list; no sites are currently proposed for addition.
