Does Rolling Hills Care Center have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2020. The violations listed here began between January 1990 and January 2020. By type: 10 monitoring and reporting, 1 reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (2 of them). EPA lists 7 as archived and 5 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.
