Does Usfs Willow Flat Campground have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in July 2020. The violations listed here began between January 1993 and July 2020. By type: 8 monitoring and reporting, 3 contaminant level above the legal limit and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (10 of them). EPA lists 10 as archived and 2 as resolved.
