waterverge.com Bristol, TN — Water Quality Report
Bristol's drinking water received a grade of B- (72.2 out of 100), indicating fair water quality. The city's 4 water systems serve approximately 53,410 residents using surface water.
Lead levels were measured at 1.0 ppb (90th percentile), well within EPA limits. PFAS testing under UCMR 5 found no detectable forever chemicals.
The system has 186 violations on record, including 12 health-based violations. 25 remain unresolved.
What to know about Bristol's water
Bristol ranks #260 out of 299 cities in Tennessee 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.
Haloacetic acid (HAA5) levels were elevated at 42.4 µg/L in UCMR 4 testing, though below the 60 µg/L EPA limit. Activated carbon filtration can help reduce these disinfection byproducts.
Hexavalent chromium (chromium-6) was detected at 0.12 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration.
The system has seen 8 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
