How does Dalton City compare with other water systems in Moultrie County?
By EPA's size categories, Dalton City is a very small system (500 people or fewer). Moultrie County has 7 active public water systems, and Dalton City is the 6th-largest of them by population served. Its population served is well below the county average of 1,801 people per system, and accounts for 3.6% of the 12,607 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 Dalton City 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 Dalton City?
EPA lists Dalton City 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. 6 of the 7 active systems in Moultrie County (86%) are also owned by a local government.
Does Dalton City have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in January 2024. The violations listed here began between January 1994 and January 2024. By type: 8 monitoring and reporting, 2 public notice, recordkeeping or other and 2 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 11 as resolved and 1 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.
