Does Avon have drinking water violations?

EPA's records list 8 violations for this system; 3 are health-based, and the most recent began in January 2024. The violations listed here began between June 1977 and January 2024.

The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 5 as archived and 3 as resolved. 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. 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.
