Does Mayan Dude Ranch have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in July 2021. The violations listed here began between August 1992 and July 2021. By type: 6 monitoring and reporting, 5 public notice, recordkeeping or other and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (7 of them).
