City of Orange Wells 25 and 27 PFAS Treatment Plant Project

The City of Orange Wells 25 and 27 PFAS Treatment Plant Project, identified by project number 3010027-002C, is funded by the State Water Resources Control Board and led by the Orange County Water District. The project involves the construction of a centralized perfluoroalkyl and polyfluoroalkyl treatment plant at Well 25 to treat water from both Well 25 and Well 27. Key infrastructure components include a water conveyance pipeline and the installation of four ion exchange vessel systems in a lead-lag configuration, along with all necessary piping, prefilters, and related appurtenances. The project is located at Water Street and Champman Avenue in Orange, California. According to a Notice of Exemption dated August 12, 2026, the project is exempt from the California Environmental Quality Act under Class 3 for the new construction or conversion of small structures due to its limited impact on water quality and small scale. Primary points of contact for the project include Environmental Scientist Robyn Mendoza and Principal Planner Shawn Nevill.
