Does Henrys MHP have drinking water violations?
EPA's records list 11 violations for this system; 1 is health-based, and the most recent began in October 2024. The violations listed here began between June 1991 and October 2024. By type: 5 monitoring and reporting, 2 monitoring, 2 public notice, recordkeeping or other, 1 reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 6 as resolved and 5 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.
