Does Antelope Ridge Hoa have drinking water violations?
EPA's records list 7 violations for this system; 2 are health-based, and the most recent began in September 2008. The violations listed here began between January 1999 and September 2008. By type: 5 monitoring and reporting and 2 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 4 as resolved, 2 as archived and 1 as unaddressed. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed.

Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
