Does Aqua Illinois-Highland Estates have drinking water violations?
EPA's records list 11 violations for this system; 3 are health-based, and the most recent began in January 2021. The violations listed here began between June 1977 and January 2021. By type: 8 monitoring and reporting, 2 required treatment not met and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 6 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.
