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

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 Curtiss Service Center?

EPA lists Curtiss Service Center 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. 73 of the 98 active systems in Cascade County (74%) are also privately owned.

Does Curtiss Service Center have drinking water violations?

EPA's records list 9 violations for this system; 2 are health-based, and the most recent began in June 2025. The violations listed here began between January 1999 and June 2025. By type: 4 monitoring and reporting, 3 monitoring, 1 required treatment not met and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Revised Total Coliform Rule (3 of them). EPA lists 8 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.
