Does Miller have drinking water violations?
EPA's records list 11 violations for this system; 2 are health-based, and the most recent began in August 1998. The violations listed here began between July 1976 and August 1998. By type: 6 monitoring and reporting, 3 public notice, recordkeeping or other and 2 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 8 as archived and 3 as resolved. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
