Idaho Tap Water Quality
EPA water quality data for 150 community water systems serving 213,552+ people in Idaho. Click any system to see violations, lead testing results, and a safety grade.
Idaho relies predominantly on groundwater from the Snake River Plain Aquifer for drinking water supply. Naturally occurring arsenic and nitrate from agricultural runoff are the most common contaminants of concern. Water is generally very hard across southern Idaho, often exceeding 180 mg/L.
