Does Umbagog Lake Stp Cmpgrnd have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in November 2022. The violations listed here began between October 2003 and November 2022. By type: 5 contaminant level above the legal limit, 3 public notice, recordkeeping or other, 2 monitoring and reporting, 1 reporting and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (7 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.
