San Tan Valley, AZ
gallon
- PFAS status
- Monitored
- Source
- EPCOR, 2024
EPCOR is monitoring San Tan Valley. Standard filters don’t remove PFAS; reverse osmosis does.
- 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 San Tan Valley’s tap.
San Tan Valley is served by EPCOR through two systems, San Tan and San Tan Anthem, and relies mostly on groundwater.
Groundwater means more arsenic and minerals
Groundwater here carries naturally higher arsenic and more dissolved minerals than surface water, so filtering your drinking water at the tap matters more.

Key contaminants
- Arsenic
- Higher in groundwater than in surface water systems. Long-term exposure is a known cancer risk. Reverse osmosis removes 88–96%.
- Hardness
- 12–16 grains per gallon. Heavy scale on fixtures, inside water heaters and in appliances is common.
- Dissolved minerals (TDS)
- Groundwater picks up more minerals than surface water, which affects taste and wears on fixtures.
- Chlorine byproducts
- THMs and HAAs from disinfection. Carbon filtration reduces them.

Questions people in San Tan Valley ask.
- Why does my water taste like chlorine in Queen Creek and San Tan Valley? Cities add chlorine to keep water safe on its way through the pipes. Queen Creek reports average levels around 0.76–0.95 mg/L. That’s within EPA limits, but enough to taste and smell, especially in summer. A whole house carbon filter removes it at every tap.
- Is East Valley tap water safe to drink? Yes, it meets federal and state legal limits. But several East Valley cities report PFAS, arsenic or chromium-6 at levels above independent health guidelines. If that worries you, a reverse osmosis system at the kitchen sink removes most of it from the water you drink.
