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. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 244 Pennsylvania systems (3.4%) list purchased surface water as their primary source.
Who owns and regulates Pittsburgh Intl Airport?
EPA lists Pittsburgh Intl Airport as owned by a local government. 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. 35 of the 65 active systems in Allegheny County (54%) are also owned by a local government.
