The Lower Duwamish Superfund cleanup will enhance the health of the Lower Duwamish Waterway for tribes and community members, support a more thriving economy, and provide a healthier habitat for fish and wildlife.
East Waterway is part of the Harbor Island Superfund Site and is regulated by the U.S. Environmental Protection Agency (EPA).
Keeping pollution out of the Lower Duwamish has been a regional priority since the 1950s.
The King County government is a major property owner and a service provider in the Lower Duwamish area. We manage transit service, wastewater facilities, trails, health services, roads and bridges, and even an international airport. Our agencies are dedicated to enhancing the quality of life and protecting public health and the environment. We are proud to be both part of the community and a representative to the people who live and work there.
Cleanups and wastewater controls alone are not enough to protect the Duwamish in the future – we all have a responsibility to do our part to prevent harmful chemicals from getting into our waterways.
