This site is under the Voluntary Cleanup Program at the Washington State Department of Ecology. The Voluntary Cleanup Program enables owners of contaminated sites to meet state cleanup standards independently and to receive technical guidance from Ecology during the process.

The Voluntary Cleanup Program enables owners to work on a contractual basis rather than under an Ecology legal order. Participants in the Voluntary Cleanup Program pay fees to Ecology to cover the department’s costs for guidance and review. Voluntary Cleanup Program sites must meet the same cleanup standards as properties formally managed by Ecology under the state’s cleanup law, the Model Toxics Control Act, created by a 1989 voter initiative.


This site is within the Tacoma Smelter Plume Program at Washington State Department of Ecology. For almost 100 years, the Asarco Company operated a copper smelter in Tacoma. Air pollution from the smelter settled on the surface soil over more than 1,000 square miles of the Puget Sound basin. Arsenic, lead, and other heavy metals are still in the soil as a result of this pollution. Arsenic and lead are toxic and can be harmful to human health. Learn more about arsenic and lead in the Dirt Alert Program. Use the Dirt Alert Map that shows the area of contamination to learn more about this and other properties within the plume.
