How does Absaroka Mountain Lodge compare with other water systems in Park County?
By EPA's size categories, Absaroka Mountain Lodge is a very small system (500 people or fewer). Park County has 49 active public water systems.

Wyoming has 352 active transient non-community water systems, 45% 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 Absaroka Mountain Lodge?

Does Absaroka Mountain Lodge have drinking water violations?
EPA's records list 8 violations for this system; 4 are health-based, and the most recent began in August 2025. The violations listed here began between December 1980 and August 2025. By type: 4 monitoring and reporting, 3 required treatment not met and 1 contaminant level above the legal limit. The contaminant or rule involved most often is E. coli (2 of them). EPA lists 4 as resolved, 2 as unaddressed and 2 as archived. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
