Does Kittitas County Water District #7 have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2026. The violations listed here began between October 1979 and January 2026. By type: 10 monitoring and reporting, 1 monitoring and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Lead and Copper Rule (4 of them).
