What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live.

Illinois has 396 active non-transient non-community water systems, 10% of the state's 3,872 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,808 Illinois systems (73%) list groundwater as their primary source.
Who owns and regulates Ameren-Cilco-Eastern Serv Ctr?
EPA lists Ameren-Cilco-Eastern Serv Ctr as privately owned.

Does Ameren-Cilco-Eastern Serv Ctr have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in February 2026. The violations listed here began between January 2025 and February 2026. By type: 10 monitoring and reporting, 1 public notice, recordkeeping or other and 1 monitoring. The contaminants or rules involved are Public Notice, Revised Total Coliform Rule, Vinyl chloride and Trichloroethylene. EPA lists 10 as archived, 1 as unaddressed and 1 as resolved. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
