OCWD; Fullerton begin operation of first PFAS extraction plant in Orange County

The Orange County Water District (OCWD) and the City of Fullerton have begun operation of the Kimberly Well 1A PFAS Treatment Plant, Orange County’s first wellhead filtration treatment plant to remove perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) from local well water.

“OCWD cannot be prouder of our amazing staff that designed and deployed this state of the art PFAS treatment system in record time to combat the PFAS chemicals which were released into the environment by third parties,” said OCWD President Steve Sheldon. “We worked closely with the city of Fullerton to construct this treatment facility to remove PFOA and PFOS from groundwater while continually meeting all state and federal drinking water standards. I want to commend our professional staff on a job very well done.”

The Kimberly Well 1A PFAS Treatment Plant uses an ion exchange treatment system made of highly porous resin that acts like powerful magnets that adsorb and hold onto contaminants. During treatment, contaminants such as PFOA and PFOS are removed. Construction began in November 2020 and the facility treats up to 3,000 gallons of water per minute.

Last year, dozens of wells in Orange County were removed from service after the state of California lowered the Response Level advisories of PFOA and PFOS. This drove local water suppliers to rely on imported water from Northern California and the Colorado River to meet the needs of their customers.

“Bringing this treatment facility online is very important. It means Fullerton can increase its use of local groundwater, which is less expensive and more reliable than imported water,” said OCWD Director and City of Fullerton Mayor Bruce Whitaker.

The Fullerton facility is the first of 25 PFAS treatment facilities being designed and constructed by OCWD in the next two years. OCWD is funding 100% of design and construction costs and 50% of operation and maintenance costs for its water suppliers like Fullerton.
