Does Gardner Water and Sanitation Dist 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 2026. The violations listed here began between January 2024 and January 2026. By type: 6 monitoring and reporting, 4 public notice, recordkeeping or other and 2 monitoring. The contaminant or rule involved most often is Public Notice (3 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.
