What does “community water system” mean?

Homes, apartments and mobile-home parks are served by these. Missouri has 1,612 active community water systems, 55% of the state's 2,943 active systems. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 177 Missouri systems (6%) list purchased groundwater as their primary source.
Who owns and regulates East Lynne Pws?

Does East Lynne 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 September 2025. The violations listed here began between November 1979 and September 2025. By type: 6 monitoring and reporting, 4 contaminant level above the legal limit, 1 required treatment not met and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Combined Radium (-226 and -228) (4 of them). EPA lists 7 as archived, 4 as resolved and 1 as unaddressed. 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. 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.
