waterverge.com Ashland, KY — Water Quality Report
Ashland's drinking water received a grade of C+ (65.7 out of 100), indicating fair water quality. The city's 2 water systems serve approximately 53,355 residents using surface water.
Lead levels were measured at 3.0 ppb (90th percentile), well within EPA limits. UCMR 5 testing detected 4 PFAS compounds, with levels exceeding EPA maximum contaminant levels in the water supply.
The system has 135 violations on record, including 37 health-based violations. 24 remain unresolved.
What to know about Ashland's water
Ashland ranks #215 out of 246 cities in Kentucky 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.
Of particular concern: PFAS "forever chemical" levels exceed the 2024 EPA maximum contaminant levels. These synthetic compounds don't break down naturally and require specialized filtration such as reverse osmosis or granular activated carbon.
Haloacetic acid (HAA5) levels were elevated at 34.8 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 0.07 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.
