PROPOSAL FOR <br />On -Call Engineering Design Services PFAS Treatment Systems <br />Kyle Matsumoto Education <br />3D CADD BS, Civil and Environmental <br />Engineering, SUNY College of <br />Kyle is an aspiring engineer with more than four years experience in Technology at Canton, New <br />the water and wastewater industry; including water pipeline York, 2018 <br />distribution systems, water booster pump stations, hydraulic analysis, Years of Experience <br />storm drainage systems, site improvement design, and membrane 4 <br />treatment design. Kyle's most recent experience includes working on <br />advanced water purification systems, injection and monitoring wells, <br />and reservoirs. <br />EXPERIENCE <br />PFAS On -Call Contract, Orange County Water District, CA. 2021. 3D CADD for IX/GAC treatment <br />for PFOS and PFOA design for 18 affected wells in the main Orange County Basin. Projects included <br />design, estimating of capital and operating costs, coordinating with vessel suppliers, and construction <br />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 />■ 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 6 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 1X 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. 2021. Design <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 MGD 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 project if they become affected by PFAS. Capital and O&M costs were also <br />prepared. <br />Albert Robles Center far Water Recycling and Environmental Learning (Formerly known as <br />GRIP), Water Replenishment District of Southern California, Pico Rivera, CA. 2019. Design <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 brine/waste disposal connection. <br />Pure Water Oceanside, Conveyance and Injection Facilities, City of Oceanside, CA. <br />2019 - Ongoing. Design Engineer, As part of the Pure Water Oceanside project Tetra Tech designed <br />the pipelines that will be constructed as part of the Advanced Water Purification Facility (AWPF) that <br />convey the advanced treated water to the existing Lower Recycled Water Pump Station and to the <br />Upper Recycled Water Pump Station that will be built along with the AWPF. In addition, Tetra Tech <br />designed three new injection wells (Well 1, Well 3, and Well 6) and conveyance pipelines to the wells, <br />totaling a maximum capacity of 6.0 MGD. <br />TETRA TECH <br />
