How does Moderne Barn compare with other water systems in Westchester County?
By EPA's size categories, Moderne Barn is a very small system (500 people or fewer). Westchester County has 273 active public water systems. Its population served is well below the county average of 3,808 people per system, and accounts for less than 0.1% of the 1,039,556 people reported by systems filed under the county. Across New York, the 8,167 active systems average 2,374 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Moderne Barn is well below that figure.
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 Moderne Barn?
EPA lists Moderne Barn 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. 185 of the 273 active systems in Westchester County (68%) are also privately owned.
