Does Red Oak Pwa have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in February 2026. The violations listed here began between April 2024 and February 2026. By type: 6 monitoring and reporting, 4 required treatment not met, 1 monitoring and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Interim Enhanced Surface Water Treatment Rule (4 of them). EPA lists 6 as archived and 6 as resolved. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed.
