How does Fayetteville compare with other water systems in St. Clair County?

Its population served is well below the county average of 6,082 people per system, and accounts for 0.2% of the 255,459 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. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 619 Illinois systems (16%) list purchased surface water as their primary source.
Who owns and regulates Fayetteville?
EPA lists Fayetteville 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. 22 of the 42 active systems in St. Clair County (52%) are also owned by a local government.
Does Fayetteville have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in August 2014. The violations listed here began between July 1997 and August 2014. By type: 4 public notice, recordkeeping or other, 4 monitoring and reporting, 3 required treatment not met and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Public Notice (4 of them). EPA lists 9 as resolved and 3 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.
