Does Yellow Lake Campsite have drinking water violations?
EPA's records list 5 violations for this system; none is health-based, and the most recent began in April 2023. The violations listed here began between April 1994 and April 2023. By type: 4 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 3 as archived and 2 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.
