PFAS Treatment at Arlington Desalter Plant

The Western Municipal Water District is implementing a project to install treatment facilities for the removal of Per- and Poly-fluoroalkyl Substances (PFAS) at the Arlington Desalter Plant located at 11615 Sterling Avenue in Riverside, California. The scope of work involves the removal of four granular activated carbon vessels and their associated piping, which will be replaced by two ion exchange vessels and associated piping in the same location. Additionally, the project includes the replacement of specific existing concrete pads and pavement within the fully developed project area. The treated water from this facility is distributed to the Cities of Norco and Corona for their customers. This project is classified under NAICS code 237990 and is identified as a forecast with a posted date of July 15, 2026. The project is claimed as a Class 3, Section 15303(d) categorical exemption for the construction of small facilities under CEQA guidelines. Ellie Yazdani, Senior Engineer, serves as the primary point of contact for the lead agency.
