Washington State has a brand-new Superfund site: the Upper Columbia River. It’s the latest development in the federal government's attempts to force a Canadian company to pay for pollution that flowed down stream into U.S. waters.

So what’s the next step for cleaning up the river? Well, it’s a long process, which Seattle-ites can see in their own backyard. Cleanup is also beginning on another Superfund site, the Duwamish Waterway, nearly a decade after the EPA released a plan.
