How does Forest Hill Hoa compare with other water systems in Flathead County?
By EPA's size categories, Forest Hill Hoa is a very small system (500 people or fewer). Flathead County has 327 active public water systems. Its population served is well below the county average of 324 people per system, and accounts for less than 0.1% of the 105,781 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 Forest Hill Hoa 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 Forest Hill Hoa?
EPA lists Forest Hill Hoa 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. 263 of the 327 active systems in Flathead County (80%) are also privately owned.
Does Forest Hill Hoa have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in December 2005. The violations listed here began between October 1982 and December 2005. By type: 12 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 6 as resolved and 6 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.
