Does Ridgeview Estates Community Assn. have drinking water violations?
Of the 12 most recent violations in EPA's records, 10 are health-based, and the most recent began in October 2025. The violations listed here began between July 2023 and October 2025. By type: 10 contaminant level above the legal limit, 1 public notice, recordkeeping or other and 1 monitoring and reporting. The contaminant or rule involved most often is Arsenic (10 of them). EPA lists 11 as archived and 1 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.
