List of Superfund sites in Washington (U.S. state)
Encyclopedia
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. 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. Seventeen others have been cleaned up and removed from the list; no sites are currently proposed for addition.
