Methodology. Includes every published Arizona city in our database where PFAS was detected in EPA UCMR5 monitoring. Built from public U.S. EPA drinking-water records (SDWIS violations + UCMR5 PFAS monitoring) for community water systems. A higher count or a lower Water Score reflects what's on the federal record — not a judgment of any utility. Meeting legal limits is not the same as zero risk.
