Description The Tacoma Smelter Plume covers a 1,000 square mile area of King, Pierce and Thurston counties. The former Asarco smelter in Ruston and north Tacoma released air emissions that carried arsenic, lead and other heavy metals. The Washington Department of Ecology is addressing soil contamination on child play areas and residential yards. This FAQ explains two key concepts that Ecology uses to make cleanup decisions and the science behind them.
REQUEST A COPY The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
