Does Rockford have drinking water violations?
EPA's records list 3 violations for this system; all are health-based, and the most recent began in September 2013. The violations listed here began between January 1985 and September 2013. By type: 3 contaminant level above the legal limit. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (2 of them). EPA lists 2 as archived and 1 as resolved.
