"For close to 100 years, the Asarco Tacoma Smelter emitted arsenic, lead and other heavy metals into the air. These windborne emissions contaminated more than 1,000 square miles covering four counties and 26 cities and towns, including University Place.
Since the smelter’s designation as an EPA Superfund site in 1983, efforts have been underway to clean up heavily contaminated soils.
According to Cynthia Walker, State Dept. of Ecology (DOE) project manager, exposure to high levels of arsenic can contribute to cancer and cardio vascular diseases while high exposure to lead is linked to neurological and developmental problems. Since 2000, the DOE and Pierce County Health Department have worked on education campaigns regarding handwashing and other measures along with providing free soil sampling and clean up at play areas at existing and new schools, childcares, parks and similar areas."
