Does Manchester Central Wd have drinking water violations?

EPA's records list 9 violations for this system; 7 are health-based, and the most recent began in November 2024. The violations listed here began between July 2014 and November 2024.

EPA lists 7 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.
