Does Maurice Municipal Water Supply have drinking water violations?
EPA's records list 8 violations for this system; 3 are health-based, and the most recent began in November 2014. The violations listed here began between October 1979 and November 2014. By type: 5 monitoring and reporting and 3 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them).
