Sediment Contamination From The Asarco Smelter
For nearly 100 years, the Asarco Company operated a copper smelter in Tacoma. The 90 acre facility sat on the border of north Tacoma and Ruston, along the waterfront. Air emissions and other smelter contaminants polluted the property, the surrounding neighborhoods, and a 1,000 square mile area called the Tacoma Smelter Plume.
In the early 1980s, the U.S. Environmental Protection Agency (EPA) began a Superfund cleanup of the site. To manage this large and complex cleanup, EPA divided the cleanup into four "operable units." The Asarco Offshore is one of these units. It consists of contaminated sediments off the shore of the property.
