Arizona Tap Water Quality
EPA water quality data for 150 community water systems serving 2,733,727+ people in Arizona. Click any system to see violations, lead testing results, and a safety grade.
Arizona depends on a mix of Colorado River water, Salt River Project reservoirs, and deep groundwater wells to supply its desert communities. Naturally occurring arsenic, fluoride, and uranium are recurring concerns in groundwater, particularly in rural areas. Water hardness is generally high, often exceeding 200 mg/L in the Phoenix and Tucson metro areas.
