How does Crown Butte Coop compare with other water systems in Morton County?
By EPA's size categories, Crown Butte Coop is a very small system (500 people or fewer). Morton County has 13 active public water systems, and Crown Butte Coop is the 6th-largest of them by population served. Its population served is well below the county average of 2,286 people per system, and accounts for 1.1% of the 29,721 people reported by systems filed under the county. Across North Dakota, the 403 active systems average 1,864 people each. Nationally, the average active community water system reports serving 6,703 people, so Crown Butte Coop 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. North Dakota has 317 active community water systems, 79% of the state's 403 active systems. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 83 North Dakota systems (21%) list purchased surface water as their primary source.
Who owns and regulates Crown Butte Coop?
EPA lists Crown Butte Coop 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. 4 of the 13 active systems in Morton County (31%) are also privately owned.
Does Crown Butte Coop have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in July 2022. The violations listed here began between July 1991 and July 2022. By type: 8 monitoring and reporting, 3 public notice, recordkeeping or other and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (7 of them). EPA lists 8 as archived and 4 as resolved. 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.
