Does Riverside Water and Sewer District have drinking water violations?
Of the 12 most recent violations in EPA's records, 8 are health-based, and the most recent began in October 2024. The violations listed here began between January 2000 and October 2024. By type: 7 required treatment not met, 3 monitoring and reporting, 1 reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Surface Water Treatment Rule (6 of them). EPA lists 9 as archived and 3 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.
