By EPA's size categories, Us Nameplate Company Inc. is a very small system (500 people or fewer). Linn County has 82 active public water systems. Its population served is well below the county average of 2,739 people per system, and accounts for less than 0.1% of the 224,589 people reported by systems filed under the county.

Nationally, the average active non-transient non-community water system reports serving 430 people, so Us Nameplate Company Inc. 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 Us Nameplate Company Inc.?

EPA lists Us Nameplate Company Inc. 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. 55 of the 82 active systems in Linn County (67%) are also privately owned.

Does Us Nameplate Company Inc. have drinking water violations?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in August 2025. The violations listed here began between July 2024 and August 2025. By type: 8 public notice, recordkeeping or other and 4 monitoring and reporting. The contaminant or rule involved most often is Public Notice (8 of them). EPA lists 5 as resolved, 4 as archived and 3 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.
