Ecology is using a large part of a $94 million settlement from Asarco to sample and replace soil in 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 do I find information for my property?

  • To find out if your property is in the service area for the Yard Program, visit our interactive map.
  • For sampling and soil replacement records for your property, visit our public database.
  • To learn about the sampling or replacement schedule for your property, visit the Yard Program Updates webpage.

How does sampling and soil replacement 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.
  • If you live in the Study Area, your property has probably already been sampled. To check if your property has existing sampling records, visit our public database. We will be wrapping up our Yard Program sampling efforts in 2017.   
  • Soil Replacement: Ecology is recommending soil replacement for yards with arsenic above 100 ppm or lead above 500 ppm.  The Cleanup Process webpage explains how soil replacement works.  You can also view this three-part video on yard cleanups.
