Lower Duwamish Waterway Site The Lower Duwamish Waterway site is a 5.5 mile stretch of the Lower Duwamish River which flows into Elliott Bay. The waterway lies south of downtown Seattle and is flanked by industrial corridors, as well as the South Park and Georgetown neighborhoods. Sediments (mud and sand on the river bottom) in and along the waterway contain a wide range of contaminants from years of industrial activity and from stormwater. The Washington State Department of Ecology and EPA are working to clean up contaminated sediment and control sources of recontamination. EPA added about five miles of the waterway to its list of Superfund cleanup sites in 2001. The contaminants in the waterway sediments include polychlorinated biphenyls (PCBs), polyaromatic hydrocarbons (PAHs), mercury and other metals, and phthalates.
