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. New York has 2,281 active community water systems, 28% of the state's 8,167 active systems. Groundwater under the influence of surface water is well or spring water that the regulator has found to be affected by nearby surface water, so it is regulated under the surface-water treatment rules. 241 New York systems (3%) list groundwater under influence of surface water as their primary source.
Who owns and regulates Delevan Village?
EPA lists Delevan Village as owned by a local government. The NY state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 43 of the 147 active systems in Cattaraugus County (29%) are also owned by a local government.
Does Delevan Village have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in January 2024. The violations listed here began between January 2009 and January 2024. By type: 8 monitoring and reporting and 4 required treatment not met. The contaminant or rule involved most often is Lead and Copper Rule (4 of them). EPA lists 10 as resolved, 1 as archived and 1 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.
