Why Arizona Tap Water Needs Extra Protection
If you live in Arizona, recent news about the quality of our water is something you should know. A recent customer notice from Global Water Resources about a positive E. coli test in Maricopa’s drinking water has surfaced. Officials acted quickly, repeat tests came back clean, and the Arizona Department of Environmental Quality (ADEQ) declared the issue resolved. But for many families, that headline should be enough to raise concerns: if bacteria can find its way into our water once, what’s stopping it from happening again?
The unfortunate reality is, even when water is declared “safe to drink,” that doesn’t always imply Arizona tap water is free of all contaminants. We can prove this with a simple water test for total dissolved solids (TDS), and in Phoenix the average is around 600 ppm… drinking water should be around 5–50 ppm. Events like this are a fantastic reminder of just how vulnerable our water supply can be to storms, dust, and infrastructure hiccups. While municipal providers work hard to maintain standards, they can’t always physically control what happens between the city pipes and your glass of water.
Why Reverse Osmosis Systems Are Essential
That’s why so many Arizona homeowners choose to take water quality as their own responsibility and invest in a reverse osmosis (RO) drinking water system. An RO system provides a powerful barrier against contaminants, including bacteria, PFAS, chlorine, dissolved solids, and more, giving your kitchen faucet the safest drinking water available.
For parents of young kids, anyone with a compromised immune system, or even households that just want their water to taste crisp and clean, RO systems are more than a convenience. They’re a layer of protection that city water alone can’t always guarantee.
At the end of the day, every homeowner should be able to trust the water coming out of their kitchen sink. However, in Arizona, where stormwater runoff and dust events are part of life, it never hurts to have that extra safeguard in place for your home.
