Does City of Kerrville have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in April 2024. The violations listed here began between January 2021 and April 2024. By type: 8 monitoring and reporting and 4 contaminant level above the legal limit. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (4 of them). EPA lists 8 as archived and 4 as resolved.
