How does Cemline Corp compare with other water systems in Allegheny County?
By EPA's size categories, Cemline Corp is a very small system (500 people or fewer). Allegheny County has 65 active public water systems. Its population served is well below the county average of 31,017 people per system, and accounts for less than 0.1% of the 2,016,109 people reported by systems filed under the county. Across Pennsylvania, the 7,217 active systems average 1,741 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Cemline Corp 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. 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 Cemline Corp?
EPA lists Cemline Corp as under public/private ownership. 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. 10 of the 65 active systems in Allegheny County (15%) are also under public/private ownership.
