Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 348 Illinois systems (9%) list purchased groundwater as their primary source.

Who owns and regulates South Roxana?

Does South Roxana have drinking water violations?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in August 2025. The violations listed here began between July 2024 and August 2025. By type: 6 monitoring and reporting, 3 public notice, recordkeeping or other and 3 monitoring. The contaminant or rule involved most often is Revised Total Coliform Rule (3 of them). EPA lists 9 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.
