New York has 5,182 active transient non-community water systems, 63% 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 The Half Way House (Gu)?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in January 2026. The violations listed here began between April 2017 and January 2026. By type: 12 monitoring. The contaminant or rule involved most often is Revised Total Coliform Rule (12 of them). EPA lists 11 as resolved 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.
