Quarterly Arsenic Results

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. More information about Arsenic can be found at http://legacy.azdeq.gov/environ/water/dw/download/epa_arsenic.pdf
