Nationally, the average active community water system reports serving 6,703 people, so Highland Subdivision is well below that figure.

Homes, apartments and mobile-home parks are served by these. Illinois has 1,773 active community water systems, 46% 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 Highland Subdivision?

Does Highland Subdivision have drinking water violations?
EPA's records list 7 violations for this system; 2 are health-based, and the most recent began in July 2025. The violations listed here began between June 1977 and July 2025. By type: 3 monitoring and reporting, 2 contaminant level above the legal limit, 1 reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 4 as resolved, 2 as archived and 1 as unaddressed. 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. 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.
