Does Antelope Creek Living Center have drinking water violations?
EPA's records list 10 violations for this system; 2 are health-based, and the most recent began in May 2018. The violations listed here began between May 1991 and May 2018. By type: 7 monitoring and reporting, 2 contaminant level above the legal limit and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 5 as resolved and 5 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.
