<br />PEAS On -Call Contract, Orange County Water District, CA. 2021.
<br />Lead Structural Engineer for IXIGAC treatment for PFOS and PFOA design for 18 affected wells in the
<br />main Orange County Basin. Projects included design, estimating of capital and operating costs,
<br />coordinating with vessel suppliers, and construction management for the following projects:
<br />■ Serrano Water District Well #5 and #9 (In Operation): This project consists of a 3,000 GPM
<br />IX System with a bag filter pre-treatment, 3,000 GPM Booster Pump Station and new chemical feed
<br />system for disinfection.
<br />■ Kimberley Well 1A (In Operation): Located on a very small site with a single well this facility is
<br />designed to produce 3,000 GPM using an IX System with a bag filter pre-treatment and new
<br />chemical feed system for disinfection.
<br />n Fullerton Main Plant (Completed Design): The Fullerton Main Plant will treat six onsite wells with a
<br />total capacity of 10,100 GPM. PFOS, PFOA and VOCs will be removed using 5 to 12 ft diameter,
<br />40,000 lb. GAC vessels that will discharge into an existing forebay then pumped into the distribution
<br />system, The remaining wells will be treated with an IX system consisting of 8 vessels and bag filters
<br />for pre-treatment.
<br />n Yorba Linda Water District Headquarters Plant (In operation): This system will treat water from
<br />10 wells with a total capacity of 17,400 GPM. An IX System consisting of 11 pairs of Lead/Lag
<br />Vessels (22 vessels total), bag filter pre-treatment, Booster Pump Station, and new Onsite
<br />Generation System for chlorine disinfection. In order to get the system on the existing site an
<br />extensive analysis of the site improvements was completed.
<br />PFAS Study for Wells ET-1, ET-2 and 78, Irvine Ranch Water District, Irvine, CA. 2 02 1. Lead
<br />Structural Engineer for a study to determine the options to add PFAS treatment to an operating VOC air
<br />stripper project. Well ET-1 operates at 2.0 MGD through one tray air stripper that discharges into a
<br />small wet well with a single booster pump station. The existing plant is located on a small lot with
<br />limited space. Project included analysis of water quality, options for IX or GAC treatment and analysis
<br />of adding wells ET-2 and 78 to the project if they become affected by PEAS. Capital and O&M costs
<br />were also prepared.
<br />PFAS Study for Five Wells, City of Downey, CA. 2021. Lead Structural Engineer for a study to
<br />determine the options to add PFAS treatment to five existing wells in Downey affected by PFOS and
<br />PFOA. Study included analysis of water quality, siting study, comparison of IX and GAC treatment,
<br />evaluation of piping wells to a central location for treatment, capital cost estimates, O&M estimates and
<br />lifecycle cost analysis. The report was used as an attachment to the City of Downey's funding
<br />application to Water Replenishment District of Southern California.
<br />Hunting Horn Reservoir Evaluation, Golden State Water Company, North Tustin, CA. 2019.
<br />QAIQC Structural Manager for the structural and seismic evaluation and study of Hunting Horn
<br />Reservoir, a partially buried, cylindrical, reinforced concrete tank with a wood framed roof. The tank has
<br />a capacity of 0.44 MG and is about 72 feet in diameter by 16 feet deep. It has a flat concrete floor,
<br />concrete masonry walls, and a wood framed roof.
