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. Pennsylvania has 1,026 active non-transient non-community water systems, 14% of the state's 7,217 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 6,632 Pennsylvania systems (92%) list groundwater as their primary source.
Who owns and regulates Horsham Clinic?
EPA lists Horsham Clinic as privately owned. The PA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 115 of the 166 active systems in Montgomery County (69%) are also privately owned.
