Ecology is using a large part of a $94 million settlement from Asarco to sample and clean up residential yards.  The Yard Program includes the most contaminated areas of the Tacoma Smelter Plume.  The program is free to all residential properties that qualify within the service area and completely voluntary.

How does sampling and cleanup work?

  • Sampling: Ecology is sampling soils in north Tacoma and southern Vashon-Maury Island for arsenic and lead. The Sampling Process webpage explains how sampling works.

  • Cleanup: Ecology is recommending cleanup for yards with arsenic above 100 ppm or lead above 500 ppm.  The Cleanup Process webpage explains how cleanup works
