Who owns and regulates Ossipee Mountains Estates?

Does Ossipee Mountains Estates have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in July 2024. The violations listed here began between July 2011 and July 2024. By type: 6 public notice, recordkeeping or other, 4 monitoring and reporting, 1 required treatment not met and 1 reporting. The contaminant or rule involved most often is Consumer Confidence Rule (5 of them). EPA lists 10 as resolved and 2 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.
