Recent compliance history is the best predictor of future problems — the year-by-year record is below.
See the record ↓Milan's drinking water received a grade of A- (87.6 out of 100), indicating good water quality. The city's 2 water systems serve approximately 1,844 residents using purchased surface water.
Lead levels were measured at 1.1 ppb (90th percentile), well within EPA limits. This system has not yet been tested for PFAS under the EPA UCMR 5 program. The system has 7 violations on record, including 1 health-based violation. 1 remains unresolved.
Milan ranks #154 out of 487 cities in Missouri for water quality, placing it mid-range in the state. The city draws from surface water sources, which are more susceptible to seasonal runoff and agricultural contamination, requiring extensive multi-barrier treatment including coagulation, filtration, and disinfection. As a small community water system, Milan may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities. The system has seen 6 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

05Pressure on Milan's watershed
Outside forces that shape what reaches the treatment plant. None of these is a verdict on the tap by itself — but each adds pressure worth knowing about.
Industrial discharge
1 facility within 10 miles reported 341k lb released to surface water in the latest EPA Toxics Release Inventory. Proximity doesn't equal tap contamination — treatment and hydrology decide — but it's pressure on the watershed.
Flood & storm history
2 federal disaster declarations on record for Sullivan County. Flooding and severe storms can overwhelm treatment plants, cause sewage overflows, and push runoff into supplies.
