Who owns and regulates Morristown Water District?

Does Morristown Water District have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in October 2024. The violations listed here began between January 1994 and October 2024. By type: 7 public notice, recordkeeping or other, 3 monitoring and reporting, 1 reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Consumer Confidence Rule (4 of them). EPA lists 11 as resolved and 1 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.
