01The verdict: is Monticello water safe?
Monticello's drinking water has significant quality concerns based on EPA testing data. With a grade of D+ (51.5/100), the system has issues across multiple categories. A water filter is recommended for all residents. The city's 4 water systems serve approximately 8,462 residents using surface water (rivers, lakes, or reservoirs).
31 unresolved violations on record
EPA records show open compliance items for this system. Most are administrative, but unresolved items are worth watching.
See what was cited ↓Lead is well under the limit
90th-percentile lead is 0.0 ppb — beneath the 15 ppb federal action level and under the 5 ppb watch threshold.
See the trend ↓17 violations in the last five years
Recent compliance history is the best predictor of future problems — the year-by-year record is below.
See the record ↓Monticello's drinking water received a grade of D+ (51.5 out of 100), indicating poor water quality. The city's 4 water systems serve approximately 8,462 residents using surface water.
Lead levels were measured at 0.0 ppb (90th percentile), well within EPA limits. PFAS testing under UCMR 5 found no detectable forever chemicals. The system has 78 violations on record, including 25 health-based violations. 31 remain unresolved.
Monticello ranks #307 out of 372 cities in Georgia for water quality, placing it among the lowest-rated 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. The system has seen 17 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
02What's in Monticello's water
Every contaminant flagged in Monticello, on one shared scale: distance to its own legal limit. The red line is the limit — anything past it is out of compliance, and the closer a bar gets, the less headroom the system has.

4 systems
4 water systems, operated under local government ownership.
8,462 people
Residents served across Monticello's service area.
Surface water systems require multi-stage treatment including coagulation, sedimentation, filtration, and disinfection to meet EPA Safe Drinking Water Act standards. These sources can be impacted by seasonal changes, stormwater runoff, upstream agriculture, and industrial discharge.
