Description From 1997-1999, sediments were collected throughout Puget Sound as part of a joint monitoring program conducted by the Washington State Department of Ecology and the National Oceanic and Atmospheric Administration. Analyses were performed to quantify concentrations of potentially toxic chemicals, responses in laboratory toxicity tests, and the structure of benthic infauna communities in sediments. Degraded sediment conditions occurred in samples that represented about 1%, high quality in about 68%, and intermediate conditions in about 31% of the total study area. Quality is also compared between six Puget Sound regions, and to estuaries nationwide. Relative to many other estuaries and marine bays along the U.S. coastline, Puget Sound sediments were ranked among the least contaminated and toxic.
REQUEST A COPY The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
