Does Manchester Utilities Authority have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in June 2025. The violations listed here began between July 2020 and June 2025. By type: 7 monitoring and reporting and 5 contaminant level above the legal limit. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (6 of them). EPA lists 10 as resolved and 2 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. 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.
