How does Pratum Elementary compare with other water systems in Marion County?
By EPA's size categories, Pratum Elementary is a very small system (500 people or fewer). Marion County has 192 active public water systems. Its population served is well below the county average of 1,921 people per system, and accounts for less than 0.1% of the 368,811 people reported by systems filed under the county. Across Oregon, the 2,536 active systems average 1,587 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Pratum Elementary 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. Oregon has 346 active non-transient non-community water systems, 14% of the state's 2,536 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,175 Oregon systems (86%) list groundwater as their primary source.
Who owns and regulates Pratum Elementary?
EPA lists Pratum Elementary as owned by a local government. The OR state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 42 of the 192 active systems in Marion County (22%) are also owned by a local government.
