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. North Dakota has 317 active community water systems, 79% of the state's 403 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 177 North Dakota systems (44%) list groundwater as their primary source.
Who owns and regulates Forest River Colony?
EPA lists Forest River Colony as privately owned. The ND state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 5 of the 9 active systems in Grand Forks County (56%) are also privately owned.
Does Forest River Colony have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in November 2025. The violations listed here began between January 2005 and November 2025. By type: 6 monitoring and reporting, 3 public notice, recordkeeping or other, 2 contaminant level above the legal limit and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 8 as resolved, 3 as archived and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
