Does Town of Thayne have drinking water violations?
EPA's records list 7 violations for this system; 4 are health-based, and the most recent began in July 2013. The violations listed here began between July 1976 and July 2013. By type: 4 contaminant level above the legal limit and 3 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them).
