Indiana Tap Water Quality

EPA water quality data for 150 community water systems serving 1,248,446+ people in Indiana. Click any system to see violations, lead testing results, and a safety grade.

Indiana relies on a mix of surface reservoirs and groundwater from glacial aquifers. Atrazine and nitrate from corn and soybean farming periodically spike in surface water systems during spring runoff. Lead and copper issues have been flagged in older industrial cities like East Chicago and Gary.
