Does New Hradec Waterworks have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in August 2025. The violations listed here began between January 2011 and August 2025. By type: 7 monitoring and reporting, 3 monitoring and 2 disinfectant level above the legal limit. The contaminant or rule involved most often is Chloramine (6 of them). EPA lists 11 as resolved and 1 as archived. 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.
