Earlier this month, four treatment plants in Orange came online and began treating local well water to remove per-and polyfluoroalkyl substances (PFAS).
Construction of the facilities took about a year to complete and are among 36 PFAS treatment facilities being designed and constructed in Orange County over the next two years by the Orange County Water District.
The facilities use an Ion Exchange (IX) treatment system made of highly porous resin that acts like powerful magnets to adsorb and hold onto contaminants and can treat up to 7,500 gallons of water per minute combined.
“OCWD’s committed staff works tirelessly to address PFAS in the Orange County Groundwater Basin,” said OCWD Director Denis Bilodeau. “Thanks to the strong partnerships with our retail providers, Orange County’s water supply remains among the highest quality in the nation. I commend our staff for working closely with the city of Orange to quickly and successfully complete these facilities.”
Orange had eight of its groundwater wells impacted by PFAS, prompting it to temporarily shut down those wells and transition to purchasing imported water from the Colorado River and Northern California.
