Private wells
A private water system in Ohio serves fewer than 15 connections and fewer than 25 people. Permits for a new or altered system require total coliform, E. coli, and nitrate samples. The secondary standard for iron is 0.3 mg/L. Manganese greensand filters are a common iron treatment. Nothing on this page claims a specific Madison County township well contains a contaminant without a sample from that well.
