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.

EPA lists Black Hills Power Incorporated as privately owned. The WY state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 51 of the 68 active systems in Campbell County (75%) are also privately owned.
Does Black Hills Power Incorporated have drinking water violations?
EPA's records list 9 violations for this system; 1 is health-based, and the most recent began in January 2013. The violations listed here began between April 1982 and January 2013. By type: 8 monitoring and reporting and 1 contaminant level above the legal limit. The contaminants or rules involved are Total coliform bacteria (TCR), Chromium, Cadmium and Barium.
