waterverge.com Weirton, WV — Water Quality Report
Weirton's drinking water received a grade of F (37.9 out of 100), indicating failing water quality. The city's 2 water systems serve approximately 19,139 residents using surface water.
Lead levels were measured at 0.7 ppb (90th percentile), well within EPA limits. UCMR 5 testing detected 6 PFAS compounds, with levels exceeding EPA maximum contaminant levels in the water supply.
The system has 141 violations on record, including 21 health-based violations. 48 remain unresolved.
What to know about Weirton's water
Weirton ranks #241 out of 248 cities in West Virginia 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.
Hexavalent chromium (chromium-6) was detected at 0.10 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 51 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
