See the risk factors ↓Livonia (V)'s drinking water received a grade of A (90.6 out of 100), indicating excellent water quality. The city's 1 water system serves approximately 9,892 residents using purchased surface water.
Lead levels were measured at 9.0 ppb (90th percentile), which is within EPA limits but above recommended levels. PFAS testing under UCMR 5 found no detectable forever chemicals. The system has 22 violations on record, including 14 health-based violations. All violations have been resolved.
Livonia (V) ranks #206 out of 810 cities in New York 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. While lead levels are within EPA limits, they are above the recommended 5 ppb threshold that health organizations consider ideal. A point-of-use filter adds an extra layer of protection.
02What's in Livonia (V)'s water
Every contaminant flagged in Livonia (V), 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.
