How does Milton compare with other water systems in Pike County?
By EPA's size categories, Milton 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 1.7% of the 15,892 people reported by systems filed under the county.

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 Milton?
EPA lists Milton 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 Milton have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in July 2025. The violations listed here began between October 1991 and July 2025. By type: 9 monitoring and reporting, 2 required treatment not met and 1 reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (7 of them). EPA lists 7 as archived, 4 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.
