You turn on the tap. The water is clear, but something about the taste or smell makes you hesitate. Maybe you’ve heard rumors about contamination, hard water, or even health risks. So you stop and ask: Is Arizona tap water safe to drink?
That simple question has a not-so-simple answer — but we’re here to make it easy. Keep reading to learn where Arizona’s tap water comes from, what's in it, and how to make sure it’s clean, healthy, and tastes great — straight from your faucet.
Is Arizona tap water safe to drink in 2025?
Legally, yes — but with caution.
Arizona’s tap water meets the EPA’s national drinking water standards, which means it is safe to drink by federal law. But legal doesn’t always mean ideal.
Here’s the truth:
- Some areas in Arizona, including Phoenix, Tucson, and Scottsdale, have reported elevated levels of contaminants.
- Hard water and chlorine are common across the state, affecting taste, smell, and appliance lifespan.
- According to the Environmental Working Group (EWG), many Arizona water systems contain contaminants like arsenic, chromium-6, and nitrates — all within legal limits, but above recommended health guidelines.
If you're drinking tap water daily (which you should!), the safest and easiest solution is to use a high-quality faucet water filter that removes these substances without breaking your budget — like TAPP Water filters.
Where does Arizona’s tap water come from and how is it treated?
Arizona’s tap water comes from a mix of sources, including:
- Surface water from rivers (Colorado, Salt, Verde)
- Groundwater from aquifers
- Reclaimed water (non-potable, used for landscaping)
Cities like Phoenix and Tucson treat water through several processes:
- Disinfection (chlorine or chloramine)
- Sediment filtration
- pH adjustment
- Fluoridation
While these processes kill bacteria and remove debris, they don’t eliminate every contaminant — and they often leave behind chlorine, mineral residue, and a bitter taste.
Regional differences: Water quality across Arizona cities
Arizona’s water quality varies significantly by region. Here’s a quick breakdown:
- Phoenix: Heavily chlorinated, very hard water, contains TTHMs and arsenic in some tests.
- Tucson: Mix of groundwater and Colorado River water; known for hard water and disinfection byproducts.
- Scottsdale: Generally better treatment systems, but still contains chromium-6 and chlorine taste.
- Rural areas: Often rely on well water, which may not be tested or treated consistently.
Hardness levels in Arizona: Is your water soft or hard?
Arizona has some of the hardest tap water in the country.
That means:
- White spots on dishes
- Dry skin and hair
- Scale buildup in kettles, faucets, and coffee machines
Hard water isn’t dangerous, but it’s definitely inconvenient — and unpleasant to drink.
While a TAPP Water filter doesn’t soften water, it removes chlorine, metals, and microplastics, which significantly improves flavor and odor.
Can you drink Arizona tap water without filtering?
You can drink it — but many people choose not to.
Here’s why:
- It doesn’t taste good
- It may contain trace contaminants
- It may carry microplastics, metals, or chlorine byproducts
Filtering your tap water with TAPP 2 makes it safer, cleaner, and better tasting — and it only takes 30 seconds to install.

FAQ: Arizona tap water safety, drinkability and filtration tips
1. Is tap water safe for kids in Arizona?
Yes, but babies and young children are more sensitive to contaminants like nitrates or metals. Using a TAPP filter is a smart extra layer of protection.
2. Is bottled water better than Arizona tap water?
Not really. Up to 25% of bottled water is just filtered tap water. Plus, it’s expensive and creates plastic waste. Filtering at home is cheaper, greener, and just as safe.
3. Do restaurants in Arizona serve filtered water?
Some do, but most serve unfiltered tap unless you ask. Bring a reusable bottle and refill it using the MyTAPP app to locate refill stations near you.
Final thoughts: Is Arizona tap water safe to drink?
Yes — but filtering is a smart move.
Arizona’s water may be legal to drink, but that doesn’t mean it’s ideal. Between hard water, chlorine, and trace contaminants, your tap water might be affecting your health, your appliances, and your wallet.
