Nitrate levels in Iowa City water and regional concerns
Iowa City water from 52 wells along the Cedar River maintains nitrate below the 10 mg/L EPA limit as 14 mg/L in the river and 8 mg/L after treatment. Deep Silurian aquifer sources dilute high nitrate near the surface, while Cedar Rapids relies on 52 shallow Cedar River wells with ASR plans under consideration to store surplus water and dilute contaminants.
