Water Quality Center   The City of Peoria has been a part of the University of Arizona (U of A) Water Quality Center (WQC) for the past two years. We support research on watershed issues that benefit the management of our surface water sources. This past year there were news reports on water quality issues in north Peoria associated with the Rose Valley Water Company. Some concerns were even raised about one of Peoria’s wells. The WQC is proposing to conduct research on "Emerging Pathogens in Arizona." The Utilities Department is in the process of supporting this important research project.

Hydrologic Computer Model 

Peoria undertook an investigation regarding regional groundwater supplies by developing a numerical computer model of Peoria’s subsurface geology and hydrology. This model will permit the City to better manage its groundwater supplies. 

Rose Valley Water Company 

Rose Valley Water Company is one of four private water companies that operate within the corporate boundaries of the City of Peoria. In November of 2002, the City of Peoria provided water, on a temporary basis, to the Rose Valley Water Company in north Peoria. Rose Valley Water Company experienced some water quality compliance issues that resulted in Maricopa County Environmental Services Department requiring Rose Valley to connect to the City of Peoria water system and temporarily shut down their two wells and storage tanks. As of January 30, 2003, the Rose Valley Water Company had completed modifications to their water system and returned to supplying water to their customers. If you are a Rose Valley Water Company customer and want more information, you should contact the company at 1-800-850-4482 or visit the company's web site at http://www.rosevalleywaterco.com.
