Nationally, the average active non-transient non-community water system reports serving 430 people, so Nas Centroid Ew Range 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.

Groundwater means the system draws its water from wells or springs fed by underground aquifers. 557 Nevada systems (87%) list groundwater as their primary source.

Does Nas Centroid Ew Range have drinking water violations?
EPA's records list 8 violations for this system; 3 are health-based, and the most recent began in January 2011. The violations listed here began between October 1991 and January 2011. By type: 5 monitoring and reporting and 3 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 5 as archived and 3 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.
