What does “non-transient non-community water system” mean?

Groundwater means the system draws its water from wells or springs fed by underground aquifers. 585 Wyoming systems (75%) list groundwater as their primary source.

Does Exxon Mobil-Labarge Sw Division have drinking water violations?
EPA's records list 7 violations for this system; all are health-based, and the most recent began in July 2013. The violations listed here began between July 1997 and July 2013. By type: 7 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (7 of them). EPA lists 5 as archived and 2 as resolved. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
