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. Indiana has 603 active non-transient non-community water systems, 15% of the state's 3,969 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 3,769 Indiana systems (95%) list groundwater as their primary source.
Who owns and regulates Lowell Commons?
EPA lists Lowell Commons as privately owned. The IN state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 86 of the 110 active systems in Lake County (78%) are also privately owned.
