What to know about Attica's water
Attica ranks #469 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.
Hexavalent chromium (chromium-6) was detected at 1.45 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.
While lead levels are within EPA limits, they are above the recommended 5 ppb threshold that health organizations consider ideal. A point-of-use filter adds an extra layer of protection.
As a small community water system, Attica may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.
The system has seen 17 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
