70.5/100
waterverge.com Morrow, OH — Water Quality Report
Morrow's drinking water received a grade of B- (70.5 out of 100), indicating fair water quality. The city's 2 water systems serve approximately 42,868 residents using purchased surface water.
Lead levels were measured at 1.3 ppb (90th percentile), well within EPA limits. UCMR 5 testing detected 1 PFAS compound, with levels exceeding EPA maximum contaminant levels in the water supply.
The system has 51 violations on record, including 7 health-based violations. 11 remain unresolved.
What to know about Morrow's water
Morrow ranks #417 out of 511 cities in Ohio 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 0.06 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 6 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
