Does Aqua Illinois-University Park have drinking water violations?
EPA's records list 7 violations for this system; 2 are health-based, and the most recent began in August 2025. The violations listed here began between October 1996 and August 2025.

The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 4 as resolved and 3 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.
