<br />PROJECT EXPERIENCE
<br />N Wells PFAS Groundwater Treatment Improvements, Santa Clarita Valley Water Agency,
<br />Santa Clarita, CA I Project Manager
<br />Project manager for study and preliminary design. Study included bench -scale evaluation of
<br />GAC and ion exchange (IX) as well as the site layout for pre -purchased treatment vessels. For
<br />6,000-gpm capacity of the three N Wells, presented 6 vessels (3 trains) using IX with 2-minute
<br />empty bed contact time (EBCT), and 24 vessels (12 trains) using granular activated carbon
<br />(GAC) with a 10-minute EBCT. Owner quickly selected IX due to site constraints. Preliminary
<br />design included site renderings that illustrated the completed site with new fencing, pre -filters,
<br />yard piping, the treatment pad, treatment vessels, and a new chemical storage building.
<br />PFAS Groundwater Treatment Facilities Design and Construction Support, Santa Clarita
<br />Valley Water Agency, Santa Clarita, CA I Technical Reviewer
<br />Project includes 3 horizontal cartridge pre -filters. Pre -purchased 12-foot-diameter treatment
<br />vessels were provided by Evoqua. IX resin was provided as PSR2+ from Evoqua and PSA694E
<br />from Purolite. System currently operating with 1 train using PSR2+ and 2 trains using PSA694E.
<br />Chemical building houses chlorine using on -site sodium hypochlorite generation and ammonia
<br />using liquid ammonium sulfate (LAS) stored in a separate room. A 24-inch diameter above-
<br />ground pipe header is used to inject chlorine followed by ammonia using in -line static mixer.
<br />PFAS Well Treatment System Preliminary and Final Design, Orange County Water District,
<br />Fountain Valley, CAI Technical Advisor
<br />Initial design project included four wells (Wells 9, 19, 23, and 24) using IX treatment with
<br />cartridge pre -filters, one of two trains of treatment vessels, and associated site work and year
<br />piping. Wells 9, 19, and 23, have a capacity of 1,400 to 2,000-gpm and required a since train of
<br />lead -lag IX 12-foot-diameter vessels. Well 24 with a capacity of 2,500-gpm, required two trains
<br />of IX vessels. Each IX treatment system includes a rinse or "flush to waste" pipeline for use
<br />following resin change -outs. Project received approval from the California Division of Drinking
<br />Water (DDW) and currently out for bid. Second follow-on project includes three wells (Wells 20,
