Does Village of Chatham Water System have drinking water violations?
Of the 12 most recent violations in EPA's records, 11 are health-based, and the most recent began in January 2026. The violations listed here began between April 2021 and January 2026. By type: 6 required treatment not met, 5 contaminant level above the legal limit and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Groundwater Rule (6 of them). EPA lists 9 as resolved, 2 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.

Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
