Mesa, Arizona — Water Quality Report
What's in Mesa's Water?
Based on the official 2024 Consumer Confidence Report (CCR) · mesaaz.gov/ccr
Mesa has two distinct water zones. The City Zone uses Salt River Project surface water (12–15 GPG). The Eastern Zone draws from groundwater wells (17–22 GPG). Eastern Zone customers face harder water and higher mineral content — and are more strongly recommended for the Best tier.

Key Contaminants in Mesa's Water
Hard Water (Wide Range)
Mesa's hardness varies dramatically by zone. Eastern Zone groundwater wells produce very hard water (17–22 GPG) that aggressively scales pipes, appliances, and water heaters.
Chromium-6
Present above health advocacy guidelines set by independent scientists. Meets EPA legal limits. Linked to increased cancer risk. Reverse osmosis removes 86–98%.
Chlorination Byproducts (DBPs)
THMs and HAAs from disinfection. Long-term exposure linked to bladder cancer and reproductive effects. Carbon filtration effectively reduces these compounds.
Arsenic
Present in both zones, higher in Eastern Zone groundwater. Naturally occurring from Arizona geology. Long-term exposure is a known cancer risk.
