Arkansas Tap Water Quality

EPA water quality data for 150 community water systems serving 1,073,518+ people in Arkansas. Click any system to see violations, lead testing results, and a safety grade.

Arkansas sources its drinking water from a mix of surface reservoirs and the Ozark and Sparta aquifers. Disinfection byproducts and total coliform violations are the most frequently reported issues. Several rural systems have struggled with aging pipes and limited budgets for infrastructure upgrades.
