How does Baylis compare with other water systems in Pike County?

By EPA's size categories, Baylis is a very small system (500 people or fewer). Pike County has 13 active public water systems. Its population served is well below the county average of 1,223 people per system, and accounts for 1.1% of the 15,892 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 Baylis 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. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 348 Illinois systems (9%) list purchased groundwater as their primary source.

Who owns and regulates Baylis?

EPA lists Baylis 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. 13 of the 13 active systems in Pike County (100%) are also owned by a local government.

Does Baylis have drinking water violations?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in March 2019. The violations listed here began between October 1986 and March 2019. By type: 11 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (2 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.
