Graves Reservoir I City of South Pasadena South Pasadena, California I Project Manager Jim led the design of ion exchange and GAC filters to address nitrate, PCE, TCE, and Carbon Tetrachloride contamination in the groundwater from the on -site well. The scope of work also included demolition of the existing concrete reservoir and replacement with a new 1-MG reinforced concrete reservoir with current seismic design standards. Archibald South Plume TCE Removal Study Chino Basin Desalter Authority I Ontario, California Project Manager Jim managed the investigation of TCE removal at the Chino II Desalter Facility. The proposed project utilizes new wells to intercept TCE in the Archibald Plume, modify the transmission piping to isolate the TCE from the remaining well water, and provide treatment using the Chino II reverse osmosis membranes and decarbonation facilities to achieve TCE removal. The work identified costs and other potential issues associated with the proposal and compared the proposed solution to other wellhead treatment alternatives for TCE. Sunrise Douglas/SunRidge Water Supply Facilities (Phase 1 and 2) ] Sacramento County Water Agency Sacramento, California I Technical Advisor Jim provided technical direction for a 4-MGD iron, manganese, and arsenic groundwater treatment facility with expansion capacity to 10 MGD, three off -site groundwater wells, and approximately seven miles of 30-inch-diameter raw water transmission line. A fast -track approach was used for initial facilities, followed by build -out at the treatment facility, which included additional pressure filters, treated water and reclaim backwash water pumps, chemical feed system modifications, two groundwater wells, and associated piping, electrical, and controls. Advanced Water Treatment Demonstration Facility Metropolitan Water District of Southern California Los Angeles, California I Project Manager Jim served as project manager for the 0.5 MGD Advanced Water Treatment Demonstration Facility, proposed as a partnership between the Metropolitan Water District of Southern California and the Los Angeles County Sanitation Districts. The Facility will provide biological NdN treatment with MBR, followed by traditional RO-UV/AOP treatment on secondary effluent from the 400-MG Joint Water Pollution Control Plant, to investigate treatment needs for indirect potable reuse. The goal of the project is to obtain DDW approval for log removal credits for MBR. In related studies, full-scale facilities of up to 340 MGD have been modeled and cost estimates prepared to support the Regional Recycled Water Supply project. Chino Desalter Authority I TOP Removal Study Ontario, California I Technical Advisor Jim led the investigation of TCP removal at the Chino I Desalter Facility. The proposed project included evaluation of water quality and operation of the wellfield and included proposed new wells to intercept the TCP plume. Treatment included GAC adsorption in conjunction with existing decarbonation systems. The work demonstrated technical feasibility of the proposed solution and identified costs and other Implementation Issues. Ocean Water Desalination Demonstration West Basin Municipal Water District Redondo Beach, California I Design Manager Jim managed the preliminary and detailed design of this 0.5-MGD ocean water desalination plant, built to demonstrate and evaluate technologies, processes, materials, sustainable operation, water quality monitoring, and impacts on the environment. This facility allowed the district to expand the information provided through the previous pilot study program and helped establish potential full-scale design parameters to be used as the basis for parametric economic studies to allow reliable prediction of cost of seawater desalination with membrane pre-treatment and reverse osmosis. Water Treatment Plant Expansion and Disinfection - By -Product Control I Antelope Valley East Kern Water Agency I Antelope Valley, California Project Manager Jim led the planning and pilot studies, through detailed design services, construction support, and start-up for the expansion and upgrade of four WTPs. The plants ranged in size from 4 to 90 MGD, The four treatment plants (Quartz Hill, Eastside, Acton, and Rosamond) were upgraded to include intermediate ozonation, deep -bed GAC filtration, and chloramines. The work required coordination of three main contractors and more than a dozen equipment suppliers, The emphasis on schedule control was critical to allow coordinated conversion of the distribution system residual. Standby disinfection was also supplied with the addition of chlorine contact basins. In addition, the largest treatment plant was expanded to 90 MGD with the addition of plate settler modules and new sludge removal mechanisms. Jim also offered final start-up and commissioning services. City of Santa Ana', On -Call Engineering Design Services for PEAS Treatment Systems RFP NO. 22-133 A-14
