Ecology is using a large part of a $94 million settlement from Asarco to sample and replace soil in residential yards. We offer soil replacement through the Residential Yard Sampling and Cleanup Program (Yard Program). 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 is completely voluntary.
We identify yards that may qualify by reviewing soil sampling results and assessing the property at the initial visit. We send a letter in the mail inviting qualifying properties to participate.
