The U.S. Environmental Protection Agency has released a long-awaited $342 million cleanup plan for Seattle’s only river.
The EPA on Tuesday said it will take about 17 years to clean up the Lower Duwamish River, which was named a Superfund site in 2001.
The plan will remove 90 percent of pollution in the river through a combination of dredging, capping and letting sediment from upriver naturally bury the toxic material.
The agency says the efforts will reduce risks from long-lasting PCBs and other toxins that have polluted the river for the past century.
BJ Cummings with the Duwamish River Cleanup Coalition says the plan is a step in the right direction, but more work will be needed to protect public health and the environment.
The Duwamish runs through Seattle’s industrial core and two residential neighborhoods before emptying into Elliott Bay.
