How does Moose Creek Ranch compare with other water systems in Teton County?

By EPA's size categories, Moose Creek Ranch is a very small system (500 people or fewer). Teton County has 27 active public water systems. Its population served is well below the county average of 323 people per system, and accounts for 0.3% of the 8,719 people reported by systems filed under the county. Across Idaho, the 1,961 active systems average 899 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Moose Creek Ranch is well below that figure.

What does “transient non-community water system” mean?

A transient non-community water system serves places where people do not stay long, such as gas stations and campgrounds, and regularly serves at least 25 people a day for at least 60 days a year. Idaho has 954 active transient non-community water systems, 49% of the state's 1,961 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,861 Idaho systems (95%) list groundwater as their primary source.

Who owns and regulates Moose Creek Ranch?

EPA lists Moose Creek Ranch as privately owned. The ID state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 18 of the 27 active systems in Teton County (67%) are also privately owned.

Does Moose Creek Ranch have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in April 2024. The violations listed here began between December 2014 and April 2024. By type: 8 monitoring and reporting, 3 monitoring and 1 required treatment not met. The contaminant or rule involved most often is E. coli (5 of them). EPA lists 11 as resolved and 1 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. 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.
