As early as the 1980s, the sediment of Sinclair Inlet in Puget Sound, Washington ( ), was known to have elevated concentrations of a number of contaminants (Malins and others, 1982). A remedial investigation of the marine Washington, was completed under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) in 1996 (U.S. Navy, 2002), and the Record of Decision (U.S. Environmental Protection Agency, 2000) was isolating a considerable volume of contaminated sediment from interactions with the benthic food web by capping and disposal pit in 2001.
