PFAS REMOVAL PLANT BEGINS OPERATION
said OCWD President Steve Sheldon.
“We worked closely with YLWD to
rapidly construct this treatment facility
to remove PFAS from groundwater and
ensure that they continue to meet all state
and federal drinking water standards. I
want to commend our team on a job well
YLWD, one of 19 water providers
that pumps water from the groundwater
basin, had all 10 of its groundwater wells
impacted by perfluorooctanoic acid
(PFOA) and perfluorooctane sulfonate
(PFOS), prompting it to temporarily shut
down wells and transition to purchasing
100%-imported water sourced from the
Colorado River and Northern California.
These wells were among dozens of
wells throughout Orange County that
were removed from service in 2020
after California lowered the Response
Level advisories of PFOA and PFOS,
two legacy PFAS compounds no longer produced in the
Located at the existing YLWD headquarters in
Placentia, the PFAS Treatment Plant uses an IX treatment
system made of highly porous resin that acts like
powerful magnets to adsorb and hold onto contaminants.
It consists of 11 IX systems (22 IX vessels), a 25 MGD
booster pump station and an upgraded onsite chlorine
generation system. During treatment, contaminants such
as PFAS are removed from the water before they go into
the distribution system. Construction began in March
2021; the facility will be capable of treating up to 25
million gallons per day.
“Bringing this treatment facility online is very
important for our customers,” said YLWD President Phil
Hawkins. “It means YLWD can safely increase its use
of local groundwater, which is less expensive and more
reliable than imported water.”
The YLWD facility is among 35 PFAS treatment
facilities being designed and constructed in Orange
County during 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 YLWD.
YLWD and 10 Orange County public water agencies filed
a lawsuit against the manufacturers of PFAS, seeking to
protect ratepayers and ensure that the associated costs,
including but not limited to treatment and replacement
water, are borne by the companies that developed and
