BACKGROUND The City is a water retailer that operates and maintains a water distribution system to deliver water to residences and businesses for domestic and irrigation uses within the city. Alameda County's Zone 7 Water Agency is the Tri-Valley’s water wholesaler that procures water from the state and regional wells, treats the water, and then sells the water to Pleasanton and other Tri-Valley water retailers for distribution. Pleasanton is a unique retailer as, in addition to purchasing water from Zone 7, the City also has an annual groundwater pumping quota of 3,500 acre-feet from its own local wells, which is approximately 20 percent of the water used in the city. The City wells are primarily utilized during the warmer time of year to meet increased water demands. The City purchases water from Zone 7, housed in underground vaults that are called turnouts, where water from Zone 7 is pushed into the City’s system and is controlled, fluorinated, and metered. The water distribution system was designed to incorporate the locations of both the turnouts and City wells to maintain balanced system pressure. Changes to the volume of water entering the system through different turnouts and wells can cause pressure variations within the system; City staff actively monitors the system to ensure that pressures in the system meet American Water Works Association standards. With the presence of PFAS in portions of the aquifer that both the City and Zone 7 wells draw from, the City has limited use of its well to only as necessary during critical periods to meet peak demands. During summer 2023 peak demands of 18 million gallons per day (mgd) were Page 93 of 228 DocuSign Envelope ID: 7FAA54C3-9A1A-4C50-9AAD-7467E7B73787
