Does Verona Waterworks have drinking water violations?
EPA's records list 10 violations for this system; 1 is health-based, and the most recent began in January 2026. The violations listed here began between July 1992 and January 2026. By type: 8 monitoring and reporting, 1 required treatment not met and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Nitrate (5 of them). EPA lists 8 as resolved, 1 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. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
