Who owns and regulates Mongolds Water System?

Does Mongolds Water System have drinking water violations?
Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in February 2024. The violations listed here began between August 2020 and February 2024. By type: 6 required treatment not met, 5 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Surface Water Treatment Rule (10 of them). EPA lists 9 as resolved and 3 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.
