How does Turner Colony compare with other water systems in Blaine County?
By EPA's size categories, Turner Colony is a very small system (500 people or fewer). Blaine County has 12 active public water systems. Its population served is well below the county average of 223 people per system, and accounts for 1.9% of the 2,672 people reported by systems filed under the county. Across Montana, the 2,378 active systems average 489 people each. Nationally, the average active community water system reports serving 6,703 people, so Turner Colony is well below that figure.
What does “community water system” mean?
A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. Montana has 853 active community water systems, 36% 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 Turner Colony?
EPA lists Turner Colony 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. 7 of the 12 active systems in Blaine County (58%) are also privately owned.
Does Turner Colony have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in December 2024. The violations listed here began between January 2023 and December 2024. By type: 7 monitoring and reporting, 3 contaminant level above the legal limit and 2 required treatment not met. The contaminant or rule involved most often is Nitrate-Nitrite (3 of them). EPA lists 7 as archived, 4 as resolved and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
