Description You are invited to review and comment on the agreed order, which requires the City of Spokane and Spokane County to complete a remedial investigation, feasibility study, and potential interim actions; and the updated Public Participation Plan, which describes how you can be involved during the cleanup process. The investigation will determine the full extent of per- and polyfluoroalkyl substances (PFAS) and other contamination in soil and groundwater, and the feasibility study will evaluate cleanup options. The order includes a scope of work and schedule for completing the investigation and study, excluding any work Spokane International Airport (SIA) will do or has already done. Interim actions could include cleaning up areas of high concern or providing safe drinking water if off-property impacts are found. The comment period is open 12 a.m. February 6 – 11:59 p.m. March 9, 2026.
