Does Mt Rose Ski Tahoe have drinking water violations?
EPA's records list 10 violations for this system; 1 is health-based, and the most recent began in August 2023. The violations listed here began between January 1997 and August 2023. By type: 8 monitoring and reporting, 1 monitoring and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (8 of them). EPA lists 7 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.
