How does Greenfield Elementary Sch compare with other water systems in Hillsborough County?
By EPA's size categories, Greenfield Elementary Sch is a very small system (500 people or fewer). Hillsborough County has 279 active public water systems. Its population served is well below the county average of 1,206 people per system, and accounts for less than 0.1% of the 336,507 people reported by systems filed under the county.

Nationally, the average active non-transient non-community water system reports serving 430 people, so Greenfield Elementary Sch 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 Hampshire has 453 active non-transient non-community water systems, 18% of the state's 2,450 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,374 New Hampshire systems (97%) list groundwater as their primary source.
Who owns and regulates Greenfield Elementary Sch?

The NH 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 279 active systems in Hillsborough County (13%) are also owned by a local government.
