Teck Cominco & Lake Roosevelt

Much of the contaminants dumped by Teck Cominco Metals have settled around the bed and banks of Lake Roosevelt in northern Washington. The pollution poses a threat to tribal members who use the reservoir to fish and for cultural and spiritual reasons, as well as the thousands of people who recreate in the area.
