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. Missouri has 228 active non-transient non-community water systems, 7.7% of the state's 2,943 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,521 Missouri systems (86%) list groundwater as their primary source.
Who owns and regulates St Pauls Elementary School?

The MO state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 33 of the 54 active systems in St. Charles County (61%) are also privately owned.
Does St Pauls Elementary School have drinking water violations?
EPA's records list 6 violations for this system; 3 are health-based, and the most recent began in April 2024. The violations listed here began between November 1993 and April 2024. By type: 3 contaminant level above the legal limit, 2 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them).
