Does Colts Neck Library have drinking water violations?
EPA's records list 8 violations for this system; 3 are health-based, and the most recent began in November 2007. The violations listed here began between January 2004 and November 2007. 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) (8 of them). EPA lists 7 as resolved and 1 as archived. 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.
