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.

Groundwater means the system draws its water from wells or springs fed by underground aquifers. 3,446 Ohio systems (89%) list groundwater as their primary source.

Does Ridgedale Jr/Sr High School have drinking water violations?
EPA's records list 9 violations for this system; 2 are health-based, and the most recent began in July 2005. The violations listed here began between October 1991 and July 2005. By type: 7 monitoring and reporting and 2 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them).
