Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 179 Missouri systems (6.1%) list purchased surface water as their primary source.
Who owns and regulates Green City Pws?

Does Green City Pws have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in December 2025. The violations listed here began between January 2000 and December 2025. By type: 5 monitoring and reporting, 4 contaminant level above the legal limit, 1 reporting, 1 public notice, recordkeeping or other and 1 required treatment not met. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (3 of them). EPA lists 9 as resolved, 2 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.
