<br />PFAS On -Call Contract, Orange County Water District, CA. 2021.
<br />Project Engineer for IX/GAC treatment for PFOS and PFOA design for 18 affected wells in the main
<br />Orange County Basin. Projects included design, estimating of capital and operating costs, coordinating
<br />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 />a 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 />■ 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 0 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 />■ 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-11, ET-2 and 78, Irvine Ranch Water District, Irvine, CA. 2021. Project
<br />Engineer for a study to determine the options to add PFAS treatment to an operating VOC air stripper
<br />project. Well ET-1 operates at 2.0 M G D through one tray air stripper that discharges into a small wet
<br />well with a single booster pump station. The existing plant is located on a small lot with limited space.
<br />Project included analysis of water quality, options for IX or GAC treatment and analysis of adding wells
<br />ET-2 and 78 to the protect if they become affected by PFAS. Capital and O&M costs were also
<br />prepared.
<br />PFAS Study for Five Wells, City of Downey, CA. 2021. Project Engineer for a study to determine the
<br />options to add PFAS treatment to five existing wells in Downey affected by PFOS and PFOA. Study
<br />included analysis of water quality, siting study, comparison of IX and GAC treatment, evaluation of
<br />piping wells to a central location for treatment, capital cost estimates, O&M estimates and lifecycle cost
<br />analysis. The report was used as an attachment to the City of Downey's funding application to Water
<br />Replenishment District of Southern California.
<br />Albert Robles Center for Water Recycling and Environmental Learning (Formerly known as
<br />GRIP), Water Replenishment District of Southern California, Pico Rivera, CA. 2019. Project
<br />Engineer for a new 13,000 acre-feet per year of fully advanced treated recycled water. Treatment
<br />process includes influent facilities, MFIUF system, RO system, UV Advanced Oxidation system,
<br />post-treatment/stabilization/disinfection, product water wet well, and brinelwaste disposal connection.
