How does Pine Butte compare with other water systems in Teton County?

By EPA's size categories, Pine Butte is a very small system (500 people or fewer). Teton County has 16 active public water systems. Its population served is well below the county average of 310 people per system, and accounts for 0.7% of the 4,960 people reported by systems filed under the county. Across Montana, the 2,378 active systems average 489 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Pine Butte 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. Montana has 1,206 active transient non-community water systems, 51% of the state's 2,378 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,994 Montana systems (84%) list groundwater as their primary source.

Who owns and regulates Pine Butte?

EPA lists Pine Butte as privately owned. The MT state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 8 of the 16 active systems in Teton County (50%) are also privately owned.

Does Pine Butte have drinking water violations?

Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in September 2025. The violations listed here began between July 2018 and September 2025. By type: 5 required treatment not met, 4 monitoring and reporting and 3 monitoring. The contaminant or rule involved most often is Groundwater Rule (8 of them). EPA lists 10 as resolved 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. 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.
