What does “community water system” mean?
A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. 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. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 587 Kansas systems (56%) list groundwater as their primary source.
Who owns and regulates City of Sylvia?

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. 18 of the 25 active systems in Reno County (72%) are also owned by a local government.
Does City of Sylvia have drinking water violations?
Of the 12 most recent violations in EPA's records, 7 are health-based, and the most recent began in January 2026. The violations listed here began between July 2024 and January 2026. By type: 6 contaminant level above the legal limit, 2 monitoring and reporting, 2 reporting, 1 monitoring and 1 required treatment not met. The contaminant or rule involved most often is Nitrate (6 of them). EPA lists 6 as archived, 3 as resolved and 3 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.
