How does Wellington compare with other water systems in Iroquois County?

By EPA's size categories, Wellington is a very small system (500 people or fewer). Iroquois County has 56 active public water systems. Its population served is about half of the county average of 442 people per system, and accounts for 0.9% of the 24,775 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 Wellington 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 Wellington?

EPA lists Wellington as owned by a local government. 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. 19 of the 56 active systems in Iroquois County (34%) are also owned by a local government.

Does Wellington have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2012. The violations listed here began between June 1977 and January 2012. By type: 11 monitoring and reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (8 of them). EPA lists 8 as resolved and 4 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.
