Does City of Oviedo have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in February 2026. The violations listed here began between November 1994 and February 2026. By type: 6 monitoring and reporting, 5 monitoring and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Revised Total Coliform Rule (5 of them). EPA lists 8 as archived and 4 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.
