How does Wells Concrete compare with other water systems in McHenry County?

By EPA's size categories, Wells Concrete is a very small system (500 people or fewer). McHenry County has 192 active public water systems. Its population served is well below the county average of 1,331 people per system, and accounts for less than 0.1% of the 255,516 people reported by systems filed under the county. Across Illinois, the 3,872 active systems average 3,204 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Wells Concrete 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. Illinois has 396 active non-transient non-community water systems, 10% of the state's 3,872 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,808 Illinois systems (73%) list groundwater as their primary source.

Who owns and regulates Wells Concrete?

EPA lists Wells Concrete as privately owned. The IL state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 154 of the 192 active systems in McHenry County (80%) are also privately owned.

Does Wells Concrete have drinking water violations?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in December 2025. The violations listed here began between April 2025 and December 2025. By type: 12 monitoring and reporting. The contaminant or rule involved most often is Antimony (2 of them). EPA lists 9 as archived, 2 as resolved and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
