How does River Valley Cooperative compare with other water systems in Cedar County?
By EPA's size categories, River Valley Cooperative is a very small system (500 people or fewer). Cedar County has 28 active public water systems. Its population served is well below the county average of 504 people per system, and accounts for 0.2% of the 14,112 people reported by systems filed under the county. Across Iowa, the 1,828 active systems average 1,718 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so River Valley Cooperative is well below that figure.
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. Iowa has 118 active non-transient non-community water systems, 6.5% of the state's 1,828 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,502 Iowa systems (82%) list groundwater as their primary source.
Who owns and regulates River Valley Cooperative?
EPA lists River Valley Cooperative as privately owned. The IA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 18 of the 28 active systems in Cedar County (64%) are also privately owned.
Does River Valley Cooperative have drinking water violations?
EPA's records list 8 violations for this system; none is health-based, and the most recent began in February 2026. The violations listed here began between April 2023 and February 2026. By type: 3 public notice, recordkeeping or other, 3 monitoring and 2 monitoring and reporting. The contaminant or rule involved most often is Public Notice (3 of them). EPA lists 6 as resolved, 1 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.

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.
