Does Miller Pws have drinking water violations?

EPA's records list 10 violations for this system; 4 are health-based, and the most recent began in July 2025. The violations listed here began between June 1980 and July 2025. By type: 4 monitoring and reporting, 4 contaminant level above the legal limit, 1 reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 6 as archived, 3 as resolved and 1 as unaddressed. 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.

Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
