Does City of Davenport have drinking water violations?
EPA's records list 11 violations for this system; 5 are health-based, and the most recent began in October 2024. The violations listed here began between March 1993 and October 2024. By type: 5 monitoring and reporting, 3 contaminant level above the legal limit, 2 required treatment not met and 1 reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (7 of them). EPA lists 7 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.
