Does Miller MHP have drinking water violations?
EPA's records list 9 violations for this system; none is health-based, and the most recent began in December 2025. The violations listed here began between May 1993 and December 2025. By type: 7 monitoring and reporting and 2 public notice, recordkeeping or other. The contaminant or rule involved most often is Lead and Copper Rule (5 of them). EPA lists 4 as resolved, 4 as archived and 1 as unaddressed. 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.
