Lower Duwamish Waterway

Source control online open house

June 29, 2021 - Aug. 23, 2021, 11 p.m.

Ecology is hosting a virtual open house to educate and involve the public in its source control efforts: stopping pollution from reaching the waterway.

From now through August 23, 2021 you can visit the open house site to:

  • Learn more about contamination in and around the waterway, partners involved in cleanup, and Ecology’s role and goals for controlling sources of contamination.
  • Explore the timeline for upland (land-based) cleanup and the status of individual sites along the waterway.
  • Share feedback on how it’s going — let us know how we can better engage with you and your community!

Source control is the process of finding sources of contamination, then stopping or reducing them before they reach the Lower Duwamish Waterway (LDW). We must make sure that sources of contamination to the LDW are sufficiently controlled before in-waterway cleanup begins. This means we must investigate more than 20,000 acres of land that drains into the river.

Source control includes a variety of actions, such as site investigation and cleanup, business inspections, controlling stormwater runoff and combined sewer overflows, coordination among agencies, and education.
