Does Oakmont PUD have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in April 2026. The violations listed here began between January 2024 and April 2026. By type: 10 monitoring and reporting and 2 public notice, recordkeeping or other. The contaminant or rule involved most often is Public Notice (2 of them). EPA lists 10 as archived and 2 as resolved.
