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.

Does Elkhart have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in September 2025. The violations listed here began between August 2003 and September 2025. By type: 5 monitoring and reporting, 2 public notice, recordkeeping or other, 2 reporting, 1 monitoring, 1 required treatment not met and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Chlorine (3 of them). EPA lists 10 as resolved, 1 as unaddressed and 1 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
