Upper Columbia River property owners can request soil sampling by contacting EPA by March 31, 2025. To find out how, read the fact sheet here.

Residential property owners may contact EPA to:

  • Request sampling
  • Check if your property is within the boundary area (see attached fact sheet map)
  • Ask if your property has been previously sampled for lead

To ask questions or discuss any of these matters about soil sampling, please contact Robert Tan, Remedial Project Manager, at Tan.Robert@epa.gov or 206-553-2580.
