What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Montana has 319 active non-transient non-community water systems, 13% 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 Green Meadow Country Club?
EPA lists Green Meadow Country Club 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. 134 of the 165 active systems in Lewis and Clark County (81%) are also privately owned.
Does Green Meadow Country Club have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in April 2026. The violations listed here began between January 2014 and April 2026. By type: 7 monitoring and reporting, 4 contaminant level above the legal limit and 1 required treatment not met. The contaminant or rule involved most often is Arsenic (4 of them). EPA lists 9 as resolved, 2 as unaddressed 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
