Phoenix Water Quality: Is Your Tap Water Safe?

Phoenix, Arizona’s water supply primarily comes from the Salt River Project (SRP) and the Central Arizona Project (CAP). Regular testing and monitoring are conducted to ensure the water meets or exceeds federal standards set by the Environmental Protection Agency (EPA), although concerns about contaminants like PFAS have surfaced in recent years.

Source of Phoenix Water Supply

Phoenix relies on a combination of surface water and groundwater. The SRP manages surface water from the Salt and Verde Rivers, while CAP delivers water from the Colorado River. Groundwater is also used to supplement the water supply, especially during periods of drought. This diverse sourcing strategy helps ensure a reliable water supply for the city’s residents.

Key Contaminants and Testing

Phoenix water is regularly tested for a wide range of contaminants, including bacteria, viruses, heavy metals (like lead and copper), and chemicals. The city publishes annual water quality reports, also known as Consumer Confidence Reports (CCRs), which detail the levels of these contaminants found in the water supply. These reports are available to the public and provide valuable information about the safety of the water.

One area of increasing concern nationwide is the presence of PFAS (per- and polyfluoroalkyl substances) in drinking water. These man-made chemicals, used in various industrial and consumer products, can persist in the environment and potentially pose health risks. Phoenix is actively monitoring and investigating the levels of PFAS in its water supply and exploring treatment options to address these contaminants. Information about PFAS and their potential health effects is available on the Wikipedia page about PFAS.

Water Treatment Processes

Phoenix employs various treatment processes to ensure the water is safe to drink. These processes include coagulation and flocculation (to remove suspended particles), filtration (to remove smaller particles), and disinfection (to kill harmful bacteria and viruses). Chlorine and chloramine are commonly used as disinfectants. The specific treatment processes may vary depending on the source of the water and the specific contaminants present.

Accessing Water Quality Reports

The City of Phoenix Water Services Department provides annual water quality reports on their website. These reports contain detailed information about the source of the water, the contaminants detected, and the treatment processes used. You can usually find the report by searching for “Phoenix water quality report” on the city’s website. The EPA also provides information about drinking water standards and regulations.
