waterverge.com Ephrata, PA — Water Quality Report
Ephrata's drinking water received a grade of C (62.2 out of 100), indicating fair water quality. The city's 3 water systems serve approximately 25,028 residents using surface water.
Lead levels were measured at 1.5 ppb (90th percentile), well within EPA limits. UCMR 5 testing detected 7 PFAS compounds, with levels exceeding EPA maximum contaminant levels in the water supply.
The system has 175 violations on record, including 21 health-based violations. 5 remain unresolved.
What to know about Ephrata's water
Ephrata ranks #248 out of 560 cities in Pennsylvania 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.
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 50.3 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 0.32 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.
