Commissioners hear update on PFAS contamination and local treatment plans

During discussion of Ambassadors and natural-resource items, commissioners turned to local water-quality concerns tied to legacy firefighting foam. A speaker summarized Department of Ecology oversight of a cleanup in the nearby valley and said contaminants have migrated into the local aquifer used by portions of the plateau.

Commissioners heard that wells not meeting drinking-water standards were taken offline, the district has attempted source blending, and the Spanish Plateau Water District is designing a roughly $20 million PFAS treatment system for the water supply shared across neighboring jurisdictions. Staff and commissioners noted the treatment work will have cost implications for ratepayers even where some cost recovery was obtained through litigation.

Commissioners framed water quality as important but largely within the purview of regional water districts and state regulators; the commission’s role is to align local outreach and water-efficiency messaging to broader climate and resilience goals.

Commissioners asked for follow‑up: one member requested a facility tour once treatment is operating and another asked staff to coordinate messaging that clarifies the commission’s scope (efficiency and consumption) vs. the districts’ regulatory and treatment responsibilities.
