Author(s) Washington State Department of Ecology
Description Washington Department of Ecology (Ecology) has identified impairments in the water column, fish tissue, and sediment in the Green/Duwamish River watershed. While the in-waterway cleanup and source control efforts will substantially improve the quality of LDW sediments and surface water, and reduce the seafood consumption risk by about 90%, some CWA-based impairments may remain following the LDW cleanup. Both the U.S. Environmental Protection Agency (EPA) and Ecology recognize the need for a scientific approach that can predict short and long-term improvements in water and sediment quality, and can subsequently predict the level of contamination in fish tissue over time, as different cleanup and restoration scenarios are implemented.
