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 under the influence of surface water is well or spring water that the regulator has found to be affected by nearby surface water, so it is regulated under the surface-water treatment rules. 24 Wyoming systems (3.1%) list groundwater under influence of surface water as their primary source.
Who owns and regulates Togwotee Mountain Lodge?
EPA lists Togwotee Mountain Lodge 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. 69 of the 112 active systems in Teton County (62%) are also privately owned.
Does Togwotee Mountain Lodge have drinking water violations?
EPA's records list 9 violations for this system; 1 is health-based, and the most recent began in June 2020. The violations listed here began between April 1991 and June 2020. By type: 7 monitoring and reporting, 1 required treatment not met and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 6 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.
