Does Maclaren River Lodge have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in January 2024. The violations listed here began between January 2009 and January 2024. By type: 6 monitoring and reporting, 3 monitoring and 3 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 10 as resolved, 1 as archived and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
