What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. New York has 704 active non-transient non-community water systems, 8.6% 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 Dutchess Day School?
EPA lists Dutchess Day School as privately owned. 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. 445 of the 546 active systems in Dutchess County (82%) are also privately owned.
