What does “community water system” mean?

Homes, apartments and mobile-home parks are served by these. Kansas has 863 active community water systems, 83% of the state's 1,041 active systems. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 278 Kansas systems (27%) list purchased surface water as their primary source.
Who owns and regulates City of Cambridge?
EPA lists City of Cambridge as owned by a local government. The KS state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 15 of the 16 active systems in Cowley County (94%) are also owned by a local government.
Does City of Cambridge have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in January 2025. The violations listed here began between August 2013 and January 2025. By type: 9 monitoring and reporting, 1 reporting, 1 monitoring and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Lead and Copper Rule (3 of them). EPA lists 4 as unaddressed, 4 as archived and 4 as resolved. 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. 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.
