Does City of Lacygne have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in February 2026. The violations listed here began between January 2020 and February 2026. By type: 7 monitoring and reporting, 2 public notice, recordkeeping or other, 1 required treatment not met, 1 disinfectant level above the legal limit and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Chlorine dioxide (3 of them). EPA lists 11 as resolved 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.
