Is Tap Water Safe to Drink in Chandler?
Yes, tap water in Chandler is safe to drink. The city blends Colorado River water, Salt River Project supplies, and local groundwater, all treated to meet EPA standards. Like most of the Phoenix metro, it is very hard, which affects taste more than safety.
Water Source
The City of Chandler treats a blend of Colorado River water delivered by the Central Arizona Project, Salt and Verde River water from the Salt River Project canal system, and local groundwater wells.
EPA Compliance Status
Meets all federal Safe Drinking Water Act standards.
Notable Contaminants & Context
- •High mineral content (hardness, sulfates) typical of desert Southwest supplies — a taste and appliance issue, not a health violation
- •Disinfection byproducts are monitored and kept within EPA limits
- •Trace arsenic occurs naturally in some Arizona groundwater; Chandler's wells are treated and blended to stay well under the federal limit

How It Compares
Chandler's multi-source blend gives it more supply resilience than single-source desert cities, and its water quality is essentially on par with Phoenix, Mesa, and the rest of the Valley — safe, but noticeably hard.
Tips
- •A softener or filter pitcher improves taste and protects appliances, but isn't needed for safety
- •Ice makers and coffee machines benefit from descaling in the Phoenix metro's hard water
- •Chandler publishes its annual Consumer Confidence Report online
