A Fresh Plan to Clean Portland’s River and Save the Island
Portland is famous for its parks, trees, and rivers, but a hidden problem lurks in the Willamette River. A 10‑mile stretch near the harbor has been listed as a Superfund site since 2000, meaning it is heavily polluted from past industrial use. The U.S. Environmental Protection Agency (EPA) has set a firm deadline: cleanup work must start by 2028. What happens next will decide how safe the river is for everyone and how much it costs local taxpayers.
The Human Toll
The river’s contamination has hurt many people, especially Black, Indigenous, and other communities of color who rely on the water for fishing, gathering, and cultural practices. Fixing the problem is not just an environmental job; it’s also a matter of justice. Yet how we clean the river matters as much as whether we do it.
The Current Plan: Expensive and Inefficient
- Scope: Dredge ~5 million tons of polluted sediment from the harbor.
- Transport: Move by truck for over a decade, ship 100 miles up the Columbia River to landfills.
- Cost: >$6 billion, most spent on transportation rather than river restoration.
- Impact: Significant carbon emissions.
A Smarter, Local Solution
Just three miles upstream lies Ross Island, a valuable natural and cultural site damaged by a century of resource extraction.
| Feature | Details |
|---|---|
| Lagoon Depth | 130 ft, prone to harmful algal blooms |
| Proposed Use | Deposit contaminated sediment in the lagoon, cap with clean material |
| Benefits | • Reduce transport distance • Cut costs dramatically • Restore the island simultaneously |
Only about 7 % of the sediment is truly hazardous and must go to a special landfill. The rest could be safely contained on Ross Island, speeding up the island’s restoration and saving billions of dollars. The plan would also protect local residents from rising utility bills and future air‑pollution risks.
The Path Forward
EPA says that the parties who caused the pollution get to decide how it’s cleaned up. Local and state leaders must therefore propose a better, science‑based solution to the EPA. A collaborative effort involving state agencies and local groups can make this happen, while keeping community voices at the center of every decision.
If Portland’s leaders act now, they can choose a path that saves money, restores the river, and protects residents. It’s an opportunity to solve two long‑standing environmental problems with one thoughtful plan.
