Water Quality Snapshot: East Moline
East Moline is a local-owned community water system that delivers drinking water to 21,374 residents in East Moline, Illinois (Rock Island County) through 7,294 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 95 total violations for this system , of which 81 (85%) are health-based, meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 12 monitoring and reporting violations are on file. The most recent violation on record dates to 2024.
The most frequently cited contaminant at this system is Surface Water Treatment Rule, recorded in 42 violations (TT, health-based). Under EPA's UCMR5 PFAS monitoring program, 2 PFAS compounds were detected in samples collected from this system, with a maximum reported concentration of 24 ppt (parts per trillion). PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.
Across Illinois, EPA tracks 5,117 public water systems serving 12,576,876 people, with 355,322 cumulative violations and 52,932 health-based violations on record. About 81% of systems in the state carry at least one violation, and state-wide the average per system is 69.4 violations. Statewide, 199 of 487 UCMR5-tested systems have reported PFAS detections (40.9%).
East Moline's 95 violations sit above the Illinois average.
All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
