How does Land and Wtr Assn compare with other water systems in LaSalle County?

By EPA's size categories, Land and Wtr Assn is a very small system (500 people or fewer). LaSalle County has 129 active public water systems. Its population served is well below the county average of 816 people per system, and accounts for less than 0.1% of the 105,319 people reported by systems filed under the county. Across Illinois, the 3,872 active systems average 3,204 people each. Nationally, the average active community water system reports serving 6,703 people, so Land and Wtr Assn 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. Illinois has 1,773 active community water systems, 46% 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 Land and Wtr Assn?

EPA lists Land and Wtr Assn 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. 99 of the 129 active systems in LaSalle County (77%) are also privately owned.

Does Land and Wtr Assn have drinking water violations?

Of the 12 most recent violations in EPA's records, 10 are health-based, and the most recent began in January 2026. The violations listed here began between July 2023 and January 2026. By type: 10 contaminant level above the legal limit and 2 public notice, recordkeeping or other. The contaminant or rule involved most often is Combined Radium (-226 and -228) (10 of them). EPA lists 10 as archived and 2 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.
