The Duwamish River is on the verge of receiving an ecological overhaul, following Tuesdayâ€™s release of a $342 million plan to bring the cityâ€™s dirty river back to health.
The lower five miles of the Duwamish River were declared a Superfund site 14 years ago. Since then the landowners – including King County, Boeing and the Port and City of Seattle – have been haggling with the Environmental Protection Agency and environmental and community groups over how best to clean the river up. More recently, hometown celebrity Macklemore has taken up the call.
The EPAâ€™s final decision will cost the responsible parties $342 million and will cover 177 acres of the lower Duwamish River. 960,000 cubic yards of contaminated sediment will be dredged from the bottom of the river, and 24 acres will be capped with clean sediment to lock away contaminants below the surface of the riverbed.
