How does Atlanta compare with other water systems in Logan County?
By EPA's size categories, Atlanta is a small system (501 to 3,300 people). Logan County has 20 active public water systems, and Atlanta is the 2nd-largest of them by population served. Its population served is about 41% above the county average of 1,203 people per system, and accounts for 7% of the 24,058 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 Atlanta 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 Atlanta?
EPA lists Atlanta 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. 10 of the 20 active systems in Logan County (50%) are also owned by a local government.
Does Atlanta have drinking water violations?
Of the 12 most recent violations in EPA's records, 7 are health-based, and the most recent began in January 2023. The violations listed here began between June 2016 and January 2023. By type: 6 contaminant level above the legal limit, 3 monitoring and reporting, 1 required treatment not met, 1 public notice, recordkeeping or other and 1 monitoring. The contaminant or rule involved most often is Arsenic (5 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.
