Nationally, the average active non-transient non-community water system reports serving 430 people, so Select 9 Site 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. Oklahoma has 84 active non-transient non-community water systems, 6.7% of the state's 1,254 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 701 Oklahoma systems (56%) list groundwater as their primary source.
Who owns and regulates Select 9 Site?
EPA lists Select 9 Site as privately owned. The OK state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 2 of the 7 active systems in Ellis County (29%) are also privately owned.
