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.
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.
