Does Mill Dam MHP, LLC have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in February 2025. The violations listed here began between May 1987 and February 2025. By type: 7 monitoring and reporting, 3 public notice, recordkeeping or other, 1 reporting and 1 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 6 as archived, 3 as unaddressed and 3 as resolved.

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.
