Does Overbrook Subdivision have drinking water violations?

EPA's records list 3 violations for this system; 1 is health-based, and the most recent began in January 2007. The violations listed here began between August 2006 and January 2007. By type: 2 monitoring and reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (2 of them).

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.
