<br />PEAS On -Call Contract, Orange County Water District, CA. 2021.
<br />Lead Electrical Engineer for IX/GAC 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 />1X 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 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 -'I, ET-2 and 78, Irvine Ranch Water District, Irvine, CA. 2 02 1. Lead
<br />Electrical 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 PFAS. Capital and O&M costs
<br />were also prepared.
<br />Well No. 32 Rehabilitation, City of Santa Ana, CA. 2017 - Present. Electrical Project Manager. The
<br />project involved the preparation of a Preliminary Design Report and plans/specifications for the
<br />rehabilitation of the well facility. The underground well would be scraped, cleaned and modified to be
<br />within an above ground CMU block control building (housing mechanical and electrical rooms). The
<br />design also included a separate on -site generation sodium hypochlorite building, 3,500 feet of 12-inch
<br />discharge pipe to John Garthe Reservoir and modification at the reservoir to connect to the on -site
<br />piping.
