Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 83 Indiana systems (2.1%) list purchased groundwater as their primary source.
Who owns and regulates Milan Water Works?

Does Milan Water Works have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in October 2025. The violations listed here began between October 1994 and October 2025. By type: 6 monitoring and reporting, 4 public notice, recordkeeping or other, 1 monitoring and 1 required treatment not met. The contaminant or rule involved most often is Consumer Confidence Rule (4 of them). EPA lists 6 as resolved, 4 as archived and 2 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.
