Does Asher Util Dev Auth have drinking water violations?
Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in October 2025. The violations listed here began between April 2025 and October 2025. By type: 6 contaminant level above the legal limit, 5 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (5 of them). EPA lists 6 as archived and 6 as resolved.
