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.
