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. Wyoming has 91 active non-transient non-community water systems, 12% of the state's 775 active systems. 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.
Who owns and regulates Basin Electric Power Co-Op?
EPA lists Basin Electric Power Co-Op 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. 7 of the 28 active systems in Platte County (25%) are also privately owned.
Does Basin Electric Power Co-Op have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in February 2019. The violations listed here began between January 1999 and February 2019. By type: 10 monitoring and reporting, 1 monitoring and 1 contaminant level above the legal limit. The contaminants or rules involved are Revised Total Coliform Rule, Total trihalomethanes (TTHM), Haloacetic acids (HAA5) and Total coliform bacteria (TCR). EPA lists 9 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. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed.
