Does Prescott Waterworks have drinking water violations?
Of the 12 most recent violations in EPA's records, 9 are health-based, and the most recent began in June 2024. The violations listed here began between November 1998 and June 2024. By type: 8 contaminant level above the legal limit, 2 public notice, recordkeeping or other, 1 required treatment not met and 1 monitoring and reporting. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (7 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.
