City of Tustin PFAS Treatment System and Influent Conveyance Project

Butier Engineering, Inc.—in collaboration with Orange County Water District (OCWD) and the City of Tustin—is providing construction management and field QA/QC services for this critical water treatment project. Portions of Tustin’s groundwater supply have been impacted by per- and polyfluoroalkyl substances (PFAS) that are prevalent in the environment and commonly used in various consumer, commercial, and industrial products. OCWD and the City of Tustin are working together to implement a new treatment system at the existing Main Street Water Treatment Plant to eliminate these compounds and continue to provide safe and reliable drinking water supplies to the Tustin customers.
