Does Monticello Housing Corporation have drinking water violations?
EPA's records list 8 violations for this system; 3 are health-based, and the most recent began in January 2026. The violations listed here began between February 1994 and January 2026. 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) (5 of them).
