How does City of Ryder compare with other water systems in Ward County?

By EPA's size categories, City of Ryder is a very small system (500 people or fewer). Ward County has 14 active public water systems. Its population served is well below the county average of 4,689 people per system, and accounts for 0.1% of the 65,645 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 City of Ryder 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 groundwater means the system buys groundwater from another public water system rather than drawing its own. 114 North Dakota systems (28%) list purchased groundwater as their primary source.

Who owns and regulates City of Ryder?

EPA lists City of Ryder as owned by a local government. 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. 9 of the 14 active systems in Ward County (64%) are also owned by a local government.

Does City of Ryder have drinking water violations?

Of the 12 most recent violations in EPA's records, 8 are health-based, and the most recent began in October 2022. The violations listed here began between April 2010 and October 2022. By type: 8 contaminant level above the legal limit and 4 monitoring and reporting. The contaminant or rule involved most often is Arsenic (8 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.
