Does Union Grove Water System have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in July 2025. The violations listed here began between January 2014 and July 2025. By type: 6 monitoring and reporting, 3 required treatment not met, 2 public notice, recordkeeping or other and 1 reporting. The contaminant or rule involved most often is Lead and Copper Rule (5 of them). EPA lists 9 as resolved, 2 as unaddressed 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
