Dredging of the Duwamish River

Dredging of contaminated soils in the Lower Duwamish is being done by the Port of Seattle, Boeing, the City of Seattle and King County. Just south of the new 14th Avenue South Bridge, known as the South Park Bridge, the work is a precursor to later Superfund efforts. The Duwamish is often called the most polluted in Washington State.
