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 means the system draws its water from wells or springs fed by underground aquifers. 7,096 New York systems (87%) list groundwater as their primary source.
Who owns and regulates Anderson Instrument Company?
EPA lists Anderson Instrument Company 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. 36 of the 53 active systems in Montgomery County (68%) are also privately owned.
