What this means
PFAS was detected in 2 of the 2 sources tested for this system, and every result in the current state dataset (2021–present) is below Washington’s state action levels — the thresholds at which the state requires customer notification and action. Detected-but-below-action-level is exactly what it sounds like: PFAS is present in at least one source at low levels, and the state does not currently require the utility to act on it.
If you’d rather not drink detectable PFAS at any level, the at-the-tap option we plan to offer is under-sink reverse osmosis — manufacturer test data shows RO membranes reduce PFAS. See the planned systems.
These results describe the water system’s sources (wells, intakes), not any individual tap — utilities blend, treat, and rotate sources. Data: Washington State Department of Health public PFAS results and Drinking Water Service Areas, dataset updated 2026-07-22. Latest test on record for this system: 2025-12-09. Informational only — not a certification of water quality and not health advice. If you have concerns about your drinking water, contact your utility or the WA DOH Office of Drinking Water.
