Does Wilson Co Rwd 12 have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in January 2026. The violations listed here began between October 2024 and January 2026. By type: 5 contaminant level above the legal limit, 4 monitoring and reporting, 2 monitoring and 1 reporting. The contaminant or rule involved most often is Haloacetic acids (HAA5) (6 of them). EPA lists 7 as archived, 4 as resolved and 1 as unaddressed. 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.

Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
