Daisy Ave., M-85 Santa Ana, CA 92703 Reference: Request for Proposals for On -Call Engineering Design Services for PFAS Treatment Systems, RFP No. 22-133 Dear Mr. Fernandez, Tetra Tech is very pleased to provide our proposal for your On -Call Engineering Design Services for PFAS Treatment Systems. In the last four years Tetra Tech has been performing similar PFAS engineering services for public agencies in both Orange and Los Angeles Counties. We are one of only a few firms that have completed the design of six PFAS projects, including the first operating project in Orange County and the largest PFAS Ion Exchange (IX) project in the United States. The Team we are proposing has extensive, local experience developed over the last five years on PFAS projects. Steve Tedesco, PE, our Project Manager has directed each of these projects making sure the Team provides high -quality engineering while meeting project budgets and schedule. Over the last four years our team has developed a large data base of costs on completed projects that can be used to provide cost certainty in this time of rapidly changing prices. To accelerate the schedule and reduce costs, Tetra Tech has developed an implementation strategy that will provide the City of Santa Ana (City) with two separate design teams working under the direction of a single Project Manager and reviewed by a single QA/QC Manager for consistency. Each team includes a Task Leader and key design team members in the following engineering disciplines: ■ Civil ■ Process/Mechanical ■ Structural ■ Electrical, Instrumentation & Control ■ Water Quality ■ 3D CADD Each team will also have access to an additional 20 engineers and production staff to use as needed to further accelerate the schedule. Tetra Tech is committing 35 full-time staff with over 90% of them located in Southern California. Our only sub -consultants on the project consist of Leighton Associates for Geotechnical Engineering and Metz Surveying for Site Topographic Survey. We have also included Alan Ludwig of Pascal & Ludwig to assist with cost estimating and constructability review. Having a local contractor who has built numerous IX plants brings additional credibility to a project. 17885 VDP Krmin A.-nua. Suite 500. Irvine.

PE November 17. 2022 Page 2 Our detailed understanding and scope of services was developed by our Team based on our successfully completed PFAS studies and design projects. In our approach to the study phase of the project we propose to review each well site and determine if it should be considered for a single well site design or be combined into a centralized system. We will determine if the existing well pump and motor is large enough to pump through the proposed PFAS plant and piping system. On centralized systems we will prepare a hydraulic model to determine the required pump and motor sizing to determine if the system is the most cost effect option. Our scope of services includes the required coordination, reports and design needed to obtain a California Division of Drinking Water (DDW) permit. The Tetra Tech team assigned to this project brings the following important advantages to this contract: ■ We have studied and designed PFAS Plants on single well sites and Centralized Treatment Facilities to serve multiple wells on a single site. Our team knows how to model, size and design well field connecting piping on busy urban streets. ■ We bring extensive local experience including four completed studies and six completed PFAS system designs. Our Headquarters Project for Yorba Linda Water District is the largest PFAS IX plant in the United States and the winner of both the ASCE Orange County Branch and ASCE Los Angeles Region Project of the Year. ■ We have obtained permits for similar PFAS projects from the DDW, other State and local agencies. We have obtained three permits from the Santa Ana DDW office for IX PFAS treatment plants. ■ Our team will use 3D modeling in all our design efforts to allow the City staff to visualize what your completed project will look like as we progress with the design. We have reviewed the City's Sample Standard Agreement attached to the Request for Proposal and concur with the provisions contained in the Agreement. Additionally, this proposal shall remain valid for a period of not less than 120 days from the date of submittal. Tetra Tech and members of our team for this project have worked together with the City on water projects for over 30 years. Let us assure you that our entire team understands the importance of this project. As Tetra Tech's client manager, I promise to ensure that our work will not only be timely but also of the highest -quality that the City expects and deserves.

TETRA TECH Page 16 city of Well 2 a. IRWD Shallow GW Unit PFAS WTP a PROJECT APPROACH ANA N TETRA TECH PROPOSAL FOR On -Call Engineering Design Services PROJECT APPROACH Project Management PFAS Treatment Systems Tetra Tech fully understands the importance of this project to the City. Our team has therefore developed a plan and a system that can complete a group of projects in the most expeditious manner possible. We have dedicated over 35 staff members (90% of which are local) to work on this project. They will be grouped into two teams which will each have a leader along with six other key staff members from various disciplines (civil, processtmechanical, structural, electrical, I&C, water quality, and 3D CADD) under the direction of our Project Manager, Steve Tedesco, PE. This approach will allow our team to work on multiple sites at the same time. Each team will also be assisted, from a pool of 20 additional staff members, to provide both technical and production assistance. Members of the pool will work on certain specifications, details, and control descriptions that are common to both teams. Our Project Manager, Steve Tedesco, will meet weekly with the City to review progress and resolve any issues. At these meetings, our team will roll out the latest plans, review the design, and solicit input. In this manner we expect to have most issues resolved before our submittals, allowing for review periods to be shortened to one to two weeks per submittal. Tetra Tech will develop and maintain a Project Management Plan (PMP) to ensure successful execution of the project. The draft PMP will be submitted within 10 days of project award, and the final PMP will be submitted within five days of receiving the City's draft comments. The purpose of the PMP is to clearly define Tetra Tech's approach, personnel, resources, project schedule, and milestones in executing and managing scope, schedule, cost, and to comply with the requirements of the project. We propose a concise document organized as follows: ■ Project Management Organization ■ Key Personnel Roles and Responsibilities ■ Project Scope, Work Breakdown Structure (WBS), and Technical Approach that defines activities and milestones ■ Detailed Activity -Based Schedule (organized consistently with the WBS) ■ A plan to keep the City up to date on the project Technical Approach We are very familiar with the City's water wells, reservoirs and distribution from our many years of service. Our team will obtain and review all relevant information on the proposed treatment sites so we can determine the best way to treat all affected wells and cost effectively get the treated water distribution system. As we work on each treatment system the first thing, we will do is confirm available information and provide a design criteria document that is site specific to each well. Pre -purchasing vessels for the project can be a significant time savings for the projects. It is critical that our design teams incorporate the pre -purchased vessels correctly into our construction bid packages. Tetra Tech has done this in the past on several IX projects. In order to take full advantage of the time saved through pre -purchased vessels, we recommend the following: ■ Design the concrete slab as a single mat foundation to hold all vessels, piping, pipe racks, drain system, and conduits. ■ Design the slab with no pipe or conduit penetrations. This will allow slab work to begin as soon as the contract is approved. ■ Design late proof packets to allow ease of installation of vessels and anchor bolts. No matter how good the vessel quality control is, it is impossible for all bolt locations to be exact in the field. TETRA TECH Page 17 PROPOSALFOR On -Call Engineering Design Services PFAS Treatment Systems ■ Layout for each site is extremely important. Design needs to accommodate large tanker trucks to deliver the GAC or IX media. These trucks need room to access the site, unload spent media, and install new replacement media. ■ We highly recommend the use of 5 micron filters as a pre-treatment step prior to IX media. This prevents fine sediments that may come from the wells or pipelines from potentially clogging the filters and/or damaging the media. ■ On large systems where there is available space it is good to have a waste backwash tank. This tank stores the waste backwash during change outs, and allows suspended particles to settle and then be pumped back to the front of the plant. Due to the "forever nature" of PFAS, it is not a good idea to send waste into either sewer or storm drain systems. ■ Installation of a drainage system on the tank slab will allow drainage water from rainfall to be collected and disposed of. It can also be used to collect, store, and alarm the operators when a leak has occurred. Since the sites are in highly urban areas, it is best to prevent any leakage from discharging off the site. ■ Consider replacing rupture disks with pressure relief valves that contain limit switches that can signal an over pressurization and alarm the wells to shut down. Rupture disk needs to be replaced after every over pressurization. All of our designs on this project will be performed using 31) CADD Revit design drawings. As each site is completed, we will provide the City with a visualization of the proposed site. Below is an example of one of our sites currently in final design. MW Preferred layout for a lead/lag configuration with pretreatment filters and backwash tank. Current code provisions for the anchorage of tanks and vessel contain specific requirements for the strength of the anchor bolts. These requirements can be found in Chapter 15 of the ASCE 7-16 and Chapter 17 of the ACI 318. The intent of these provisions is to avoid catastrophic, brittle failures of the concrete at anchor bolts by ensuring that the concrete at an anchor bolt group has significantly more strength than the anchors themselves. The anchor design provisions effectively prevent the use of post -installed anchors because of their limited bond strength. Cast -in -place anchors must be used for tanks and vessels, but cast -in -place anchor bolts are difficult to locate accurately. The use of cast -in -place anchors requires additional time and TETRA TECH Page 18 PROPOSALFOR On -Call Engineering Design Services PEAS Treatment Systems cost during construction, as full-size anchor layout templates must be created for each vessel, the templates must be field located by surveyors and secured to the formwork to keep the anchors from shifting as the concrete is placed. The convenience of post -installed anchors can be reclaimed by the use of late pour pockets at each of the tank legs. Please refer to the sketches below for a typical plan and section of the late pour pockets. A small portion of the tank foundation will be blocked out with formwork so that the space within the block -out will not be filled with concrete at the time the rest of the foundation concrete is placed. The reinforcing for the foundation will run through the late pour block -out, and it will be located to miss the tank anchors. This will create relatively clear areas at each tank base plate where the cast -in -place anchor bolts can be located with some freedom for field adjustments. Additional reinforcing stirrups (if required) may be placed in the late pour pocket for increased concrete strength. After the tanks are properly located and temporarily supported, the late pour pockets will be filled with high strength cementitious grout. After the grout in the late pour pocket sets, final adjustments to the tank height may be made, to plumb and level the tanks.

IX treatment for PFAS removal is configured in 2-vessel trains, with one train acting as the lead and the second train acting as the lag (i.e. the vessels operate in series). Santa Ana Well 26 was evaluated to consider what a WAS treatment system for this site could look like. Santa Ana Well 26 supplies the East Reservoir and Pumping Station. The well production from 2010 to 2022 varied from 1,565 gpm to 2,454 gpm. Design criteria of the existing well are summarized in Table 1.

Ion exchange resin has a high headloss per ft of bed depth, and for this reason many facilities cap their treatment capacity based on a maximum resin depth of 3.7-ft per vessel. The recommended treatment capacity for PFAS removal is 500 to 1,100 gpm per 10-ft vessel train and 700 gpm to 1,600 gpm per 12-ft vessel train. Santa Ana Well 26 could be configured with two (2) 12-ft trains and treat the maximum production currently reported, or two (2) 10-ft trains to treat the well pump design flow rate of 2,050 gpm. Either IX system should also consider the installation of 5-micron pre-treatment cartridge or bag filters ahead of the IX vessels.

The headloss for the IX vessels is calculated as a function of the resin depth as it relates to the flow through the IX train. The system losses were calculated for both clean pre-treatment filters and pre-treatment filters with maximum dP prior to replacement. Table 3 summarizes the design points at the maximum and minimum lifts for the pretreatment conditions as well as the proposed IX treatment condition.

The existing well pump curve is not provided at this time, therefore a generic curve is included to indicate a pump curve that would be capable of incorporating treatment. During the design process Tetra Tech will evaluate all of the actual existing well pump curves against the calculated new system curve to determine the well pump's ability to meet the new system pressure requirements with PFAS treatment. The maximum flow rate the pump will operate at with the new treatment will be presented, and if unacceptable recommendations made for modifications such as adding bowls, changing motor size, or replacing the well pump entirely. cico = at sc Figure 1.

TETRA TECH Page 111 PROPOSALFOR On -Call Engineering Design Services Pilot Testing Data and DDW Permitting HAS Treatment Systems Orange County Water District (OCWD) pilot test of non -potable well (Bessie Well) located in Anaheim, CA near Warner Basin and pilot results at neighboring Water Replenishment District (MD) sites have all demonstrated excellent ability of many IX resins to successfully remove PFAS containments. Table 4 compares key organic and inorganic water quality data from a generic OCWD well with WRD and OCWD PFAS pilot tests. It is observed that the water quality of the example well is generally similar in PFOA, PFOS, and other relevant IX water quality parameter concentrations to that of OCWD-BESS. Given that the pertinent water quality parameter concentrations are similar between the pilot test source water and the example well, and that the pilot testing has shown several IX products successfully remove PFOA and PFOS, DDW permitted implementation of IX at the example site based off of the OCWD pilot data and a site specific lead -lag performance model to approximate lag performance at the speck example well site. Once water quality data is received a similar comparison would be provided for any Santa Ana wells that require treatment. TABLE 4.

TETRA TECH Page 112 PROPOSALFOR On -Call Engineering Design Services PFAS Study PFAS Treatment Systems Our team has been involved in numerous PFAS Studies for water systems in Southern California. Our approach is to start with a site visit to each proposed well site followed by a detailed review of available record drawings. It is our understanding that the City has approximately 6 to 8 wells that will need to be considered for PFAS treatment. Once we have completed this work we would proceed with the following: ■ Obtain and review 3 to 5 years of water quality data from each well. This data will be reviewed and analyzed to confirm that the water quality is within the range required for effective PFAS treatment with IX media. ■ Determine if any of the wells have issues with sand, turbidity or suspended solids that would affect the 5 micron pretreatment filter and/or the IX media. ■ Prepare a comparison of each wells water quality to the pilot results in the OCWD Pilot Report. This data will be used to determine if the City wells could use the existing pilot test results or if they would require additional pilot testing be performed. ■ Using areal photographic mapping determine proposed layouts for each site considering both construction working room and room for future maintence including IX media change outs. ■ Determine which sites could be piped together to allow for a centralized treatment system to treat all or some of the wells. See the figure below for a typical centralized treatment system layout. CENTRALIZED TREATMENT SYSTEM WELL FIELD TO DISTRIBUTION SYSTEM We would then work closely with the City staff to narrow down the options to 3 or 4 which include both centralized and single well treatment plants. The next step in the process would be to build a hydraulic computer model that could analyze the operations of each of the 3 to 4 options. The hydraulic computer model would include the following inputs: ■ Pump curves for all affected wells ■ New Pipelines from the Wells to the centralized treatment plant ■ Storage reservoirs (if required) ■ Booster Pumps (if required) ■ Existing City Distribution pipeline size and pressure where treated water will be delivered to The models are run and updated to obtain the optimum pipe diameter, pump, and motor sizing for each option. Once this is completed our team will then prepare capital and operational costs for each option. Our draft and final reports will provide the costs indicating the total capital cost, annual operating costs and the cost per acre feet of water produced.
