The need for the water supply alternatives evaluation was driven by increasing costs for PFAS treatment, regulatory uncertainty, and operational implications. Two categories of water supply alternatives would be considered: alternatives that continue to utilize the City's groundwater quota such as new City wells located in areas without PFAS, and alternatives that do not continue to utilize City' s groundwater quota such as purchasing 100 percent of pumping quota. The City and its consultant team have brainstormed a number of alternatives including some that could be done in partnership with Zone 7. These options would include a regional PFAs Treatment Facility (upsizing a Pleasanton facility to accommodate regional needs), additional wells in the Bernal subbasin and other such options. The Pleasanton team would like to work with Zone 7 to further explore these alternatives, and then evaluate them and the non-Zone 7 alternatives based on multiple criteria including cost, reliability, timeliness, and operational complexity. Staff recommends working with Pleasanton to explore such options. Staff recommends that... John Bauer South Pleasanton z
