The Arizona Department of Environmental Quality (ADEQ) requires the Annual Water Quality Report to be available to the public by July 1st each year.
In effort to be fiscally responsible and conserve natural resources, this report is being delivered primarily through electronic distribution. Limited hard copies of the report are available at the City Library, City Hall, and Public Works.
To request a hard copy, contact Water Operations.
Each year the City of Prescott is required to pull quarterly Arsenic samples at EPDS (Entry Point to Distribution System) 011 located in Chino Valley. This sample is taken to ensure Arsenic levels stay below Federal and State regulatory limits. The MCL (Maximum Contaminant Level) for Arsenic in drinking water is 10 ppb (Parts Per Billion). Below are the quarterly results for the most recent year of City of Prescott Arsenic testing.
