Groundwater PFAS Treatment Facility
June 27, 2025
The ACWD Groundwater PFAS Treatment Facility Project involved the construction of a new 6 million gallon per day ion exchange treatment system at the District’s Blending Facility to remove PFAS contaminants from the groundwater supply. The project included the installation of treatment equipment, piping, electrical systems, instrumentation, and supporting civil improvements. Construction began in December 2023, and the facility was placed into service in September 2024. Final site restoration and automation work were completed by March 2025. The facility is now fully operational and delivering PFAS-free water to the community, with future expansion capacity up to 15 MGD.
