What’s in Mesa’s water?
Every recommendation starts with your city’s water report.
Mesa, AZ
gallon
- PFAS status
- Not flagged
- Source
- City of Mesa, 2024
- Grains per gallon (gpg)
- How much dissolved calcium and magnesium is in your water — the minerals that leave white crust on faucets, spots on glasses and buildup in your water heater. Under 1 gpg is soft; 7 and up is hard; above about 10.5 is very hard.
- PFAS
- Man-made “forever chemicals” from things like non-stick pans, waterproofing and firefighting foam. They don’t break down, so they can build up in the body over time. You can’t see, smell or taste them.
LOCAL DETAILS
What’s in Mesa’s tap.
Mesa has two water zones. The City Zone uses Salt River Project surface water at 12–15 grains per gallon. The Eastern Zone draws from groundwater wells at 17–22 grains, so it is harder and carries more minerals.
Check which Mesa zone you’re in
If you’re in east Mesa, expect the harder end of the range (17–22 grains). Size your softener for that, not the city average.

Key contaminants
- Hardness
- 12–15 grains in the City Zone and 17–22 grains in the Eastern Zone. The eastern wells scale up pipes, appliances and water heaters quickly.
- Chromium-6
- Above health guidelines set by independent scientists, while within the EPA’s legal limit. Reverse osmosis removes 86–98%.
- Chlorine byproducts
- THMs and HAAs from disinfection. Carbon filtration reduces them.
- Arsenic
- Present in both zones and higher in Eastern Zone groundwater. Comes naturally from Arizona geology.
