Does Asticou Inn have drinking water violations?

By type: 2 monitoring, 1 required treatment not met and 1 monitoring and reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (3 of them). EPA lists 2 as resolved, 1 as unaddressed 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.
