Water Quality Data

The data presented on the following pages provide a detailed chemical analysis of Peoria’s water supply for calendar year 2005, during which Peoria supplied water through two different systems.  Data from the Central Area water system and the Vistancia Area water system are reported separately.  City of Peoria water customers west

 of the Agua Fria River and north of the Loop 303 / Happy Valley Road alignment received water from the Vistancia Area system; all other City of Peoria water customers received water from the Central Area system.  The data tables are color-coded to match the water system area (see map on previous page for colors). Should you have other water quality questions, contact us at waterquality@peoriaaz.gov or 623-773-7286.

Radon is a radioactive gas that you cannot see, taste, or smell. It is found throughout the United States. Radon can move up through the ground and into a home through cracks and holes in the foundation. Radon can build up to high levels in all types of homes. Radon can also get into indoor air when released from tap water from showering, washing dishes, and other household activities. Compared to radon entering the home through soil, radon entering the home through tap water will in most cases be a small source of radon in indoor air. Radon is a known human carcinogen. Breathing air containing radon can lead to lung cancer. Drinking water containing radon may also cause increased risk of stomach cancer. If you are concerned about radon in your home, test the air in your home. Testing is inexpensive and easy. For additional information, call your state radon program or call EPA’s Radon Hotline (800-SOS-RADON).
