23 Jan Vista Field Cleanup Action Plan Available for Public Review
KENNEWICK, Wash. – Port of Kennewick invites the public to review and comment on its Cleanup Action Plan to address a small area of contaminated soil at a property within the Vista Field development. The Port is making the Cleanup Action Plan available for review and comment through February 10. Comments may be made online at vistafield.com/pfas or provided in person at the Port of Kennewick’s regular Board of Commissioners meeting, February 10, to be held at 2:00p.m., within the port offices at 350 Clover Island Drive, Suite 200 Kennewick, WA 99336. A copy of that plan can be accessed at:

The cleanup consists of excavation and removal of soil that shows evidence of PFAS contamination (approximately 30 cubic yards—roughly 2.5 to 3 dump truck loads of dirt), which will be transported to a licensed disposal facility. Before the area is backfilled with clean soil, confirmational samples will be taken to ensure the remaining soil does not exceed applicable cleanup levels. Following the work, Landau Associates (Landau) will provide Washington Department of Ecology (Ecology) a summary report and request a “No Further Action” determination.
The Port was informed in June 2025 that soil samples collected at a property by the owner during construction activities contained low concentrations of per- and polyfluoroalkyl substances (PFAS). In response, the Port initiated additional sampling at the subject property to confirm the initial findings and expanded sampling across the broader 103-acre Vista Field area. The Port hired Landau to evaluate the presence of PFAS at Vista Field utilizing a sampling methodology that meets Ecology standards. Results from samples collected by Landau in September 2025 and December 2025 show that only one localized area requires clean up; thereafter Landau prepared the proposed cleanup action plan.
The Port has worked closely with the Lot 31 property owners and appreciates their cooperation and patience throughout the environmental testing and evaluation process. Once the cleanup is completed, the Port will be able to move forward with the parking lot and utility improvement projects at Vista Field that have been on hold since last summer.
