King County Dirt Alert
Outreach and education for the Tacoma Smelter Plume Project
The ASARCO smelter in Ruston, WA closed in 1986 after nearly 100 years in operation, but arsenic and lead remain in the soil and will continue to be a health risk for years to come. Public Health—Seattle & King County is working in partnership with the WA State Department of Ecology to share information about this issue.
Should you be concerned about arsenic and lead in your soil?
