assist in this effort, a process that is scheduled to take about nine months. Zone 7 may also be advancing its own plans for adding well capacity in the Bernal subbasin. During the period for the modeling effort, staff discussions may occur to develop key terms for a possible joint project agreement. This way, at the end of the modeling effort, the City would be in a position to decide on proceeding with a City-only two new wells project or pursuing a joint project with Zone 7. There is high confidence that the modeling will support placing new wells within the Bernal subbasin, free of PFAS and isolated from contamination. However, if that were not the case based on modeling or test well results, staff would update the City Council and re-evaluate the water supply alternative recommendation accordingly. Beyond the next nine months of modeling and other preliminary work, the remainder of the schedule for completing the work is as follows- Activity Timeframe Collaborate with Zone 7 FY24 • Groundwater Modeling • Develop key terms for possible joint project Perform well tests and initiate the design of well FY25 facilities Complete final design, construct and equip wells, FY26 and FY27 then begin operation Project Progress Summary The project progress to date is summarized below by task: 1. Project Management ONGOING BC will provide project management services including oversight of project staff, budget, and schedule. This is an ongoing task related to the management of the study. 2. Information Collection and Review COMPLETED The project team has gathered and reviewed data and information from the City and Zone 7, including the Zone 7 groundwater model. 3. Alternatives Development COMPLETED BC developed a list of water supply alternatives, which was reviewed and confirmed by the Water Supply Alternatives Ad Hoc Subcommittee and shared with Zone 7 for feedback. This list was intended to be comprehensive, and an initial screening step eliminated alternatives that were not feasible or that had more significant costs and lower benefits relative to the PFAS Treatment and Well Rehabilitation Project. Alternatives (or combinations of other options that can produce 3,500-acre feet/year) that passed the initial screening were evaluated in further detail based on the criteria developed. Page 5 of 6
