Phoenix Water Quality Will Shock You...


Phoenix Arizona

Phoenix water quality is sourced primarily from surface water and used by over 1.5 million residents. According to data from the Environmental Working Group (EWG), based on reports by the Arizona Department of Environmental Quality and U.S. EPA testing from 2013-2021, the city’s water has met federal safety standards. Although legally compliant, Phoenix water still has some contaminants detected which exceed health guidelines established by independent experts.


Contaminants Found in Phoenix's Water


In the latest testing cycles, Phoenix’s water showed the presence of several contaminants, some of which exceeded EWG’s health guidelines, including:

  1. Arsenic: Detected at levels over 1,200 times EWG's health recommendation, posing a potential cancer risk.

  2. Chlorite and Nitrate: Chemicals linked to health risks, especially in higher concentrations.

  3. Haloacetic Acids and Trihalomethanes: Byproducts of water disinfection that can elevate cancer risks if consumed over time.


Addressing "Forever Chemicals" (PFAS) Concerns


Recent EPA data has shown a detection of PFAS, a group of human-made chemicals resistant to heat and often are referred to as "forever chemicals." Regulations aren't perfect and are improving, but these impactful chemicals have raised several health concerns.


How Homeowners Can Improve Water Quality


  1. To ensure safer drinking water, consider installing filtration systems capable of reducing harmful contaminants. Options include:

    1. Reverse Osmosis Systems: Effective in removing many contaminants such as arsenic, nitrate, and PFAS in the water you drink.

    2. Activated Carbon Filters: Suitable for reducing chlorite, chlorine byproducts, and certain volatile organic compounds.

    3. Whole-Home Water Filtration Systems: A maintenance-friendly solution for addressing contaminants throughout the entire home in one system.


Why Up-to-Date Regulations Are Essential


The legal standards for drinking water contaminants haven't been significantly updated in nearly two decades. While Phoenix’s water is legally compliant, stronger regulations could better protect residents’ health. Community members can advocate for more stringent standards and support local efforts to reduce pollution at the source.
