Press 2 for Tacoma Smelter Plume

Project Information

Arsenic and lead in the soil

The mining company Asarco once operated two copper smelters in Washington State; in Everett and Tacoma. Emissions of arsenic and lead contaminated soils for miles around the former stacks.

The Tacoma Smelter Plume covers 1,000 square miles of King, Pierce, and Thurston counties. Ecology and EPA have been cleaning up yards and play areas in Tacoma since 1993. The Everett Smelter contaminated a one square mile area in north Everett. Ecology has been cleaning up yards in Everett since 1999.
