STATEMENT OF WORK

1. Project Objectives
The purpose of this project is to perform a geotechnical investigation, evaluate the feasibility, provide planning, and to develop a feasibility study and report for the Delta Water Treatment Plant (DWTP) Groundwater Recharge Basin Improvements Project. The geotechnical investigations will establish the subsurface soil characteristics and evaluate if they have the likelihood of supporting a successful groundwater recharge project.

2. Proj ect Scope
Pr
ovide professional services to conduct a geotechnical investigation and hydrogeologic characterization of a portion of the DWTP site for direct groundwater recharge and recovery potential. The intent of this effort is to conduct a subsurface investigation at the DWTP site to:
• Determine soil profile characteristics for suitability of infiltrating surface- applied water for direct recharge
• Subsurface lithology
• Groundwater levels
• Potential storage volume (volume of water that can be recharged and recovered while avoiding local impacts)
• Specific yield
• Hydraulic conductivity
• Water quality
D
ata acquired and conclusions from this work effort will be used to confirm the feasibility of a direct DWTP site recharge project. Engineering design, environmental review, water rights and project funding will be the focus of a future project phase.

3. Specifications
T
he City uses ArcGIS. The data natively is in California State Plane grid 3 EPSG 2227 – units are in feet. The GIS system does not adhere to a vertical system.

The horizontal and vertical coordinate system and datums will be based on the North American Datum of 1983 (NAD83) converted to the California Grid EXHIBIT 2

CWRE, completed a pilot test and feasibility analysis for an aquifer storage and recovery well that has many of the same issues that will be encountered for this project including demonstrating that infiltrated water will not impact nearby supply wells. Amer Hussain, PE supported by Joe Turner, PG, CHG have also recently completed a feasibility assessment of a sixty acre property proposed for use as an infiltration basin in Tulare County. This work included a literature search to assess water quality , potential regional effects from recharge, and completion of soil borings and infiltration testing to assess the suitability of the on-site soils for recharge.

Team members Brandon Steets , PE and Scott Struck , PhD are assisting the California State Water Resources Control Board in the development of statewide standards for dry wells and their use in infiltration projects. These structures may become an important component of the overall design of the recharge basin to allow water to bypass low permeability sediments that are known to occur within the shallow surface.

Partnered with the Department of Energy’s Lawrence Berkley National Laboratory and the United States Bureau of Reclamation and Geological Survey, Brandon and Scott have also developed the use of electrical resistivity tomograph (ERT) sensors for assessing the pathways of recharge through the vadose zone.

Site Knowledge: Arthur Forma, PG, CEG, CHG, EIT and his team have been working for over 10 years on groundwater issues at the nearby Lincoln Center site (more information about this project may be found on page 4). The project has included development of a detailed hydrogeologic conceptual model used to assess aquifer properties, soil permeabilities, fluid migration pathways from the surface to the vadose zone , groundwater quality, and potential effects on nearby supply wells from groundwater extraction wells. They have also designed and installed groundwater extraction wells that provided additional information on the aquifer properties in the area. Joe Turner assis ted with the development and design of future groundwater monitoring networks that were included in the Eastern San Joaquin Groundwater Basin G roundwater Sustainability Plan (GSP) and has also published papers describing the makeup of the geologic formations that exist beneath the DWTP and how to recognize these formations during the drilling of soil borings.

Long-Range Planning : Geosyntec has been assisting clients with a broad range of issues related to groundwater resources and mechanisms for recharge including initial assessments, pilot testing, water market development, funding, permitting, and satisfying requirements of California’s Sustainable Groundwater Management Act (SGMA). From this experience, we are well aware that successful planning during feasibility assessments requires foresight for future portions of the project so that appropriate data and conceptual designs take into account future considerations and portions for the project. For example, our proposed approach for data collection considers the full cycle of the project, including long-term and full- scale operation and maintenance, and analysis for future proposal solicitation packages to obtain grant funds for project construction.

High-Quality Deliverables: Geosyntec is known for providing our clients with the highest quality of service from draft preparation and filing to public meeting support. We understand the need to work closely with the City and stakeholders when finalizing a deliverable and will maintain direct contact with your team to provide accurate, high-quality project deliverables.

Project Description
As part of the Tulare Lake Subbasin’s GSP implementation, Geosyntec conducted an Aquifer Storage and Recovery (ASR) pilot test in an existing active irrigation supply well within the South Fork Kings GSA (SFKGSA). This GSA has poor soils that are not amenable to surface infiltration, and the objective of the test was to evaluate the potential for direct injection as a method for developing groundwater storage using excess surface water when it is available. The test involved comprehensive monitoring of water levels and water quality and was designed to be compatible with typical irrigation operations in the area. Twenty-six million gallons of water was injected into the aquifer, stored for 45 days, and then recovered for irrigation.

Geosyntec’s Scope of Services
Geosyntec was retained by the South Forks Kings GSA to design and complete a pilot test for ASR using an existing active irrigation supply well. The goal of the pilot test was to demonstrate that active irrigation wells could be used for ASR so that SFKGSA could develop an expanded ASR program for the basin.

Geosyntec prepared a work plan for submittal and approval of the pilot test to the Central Valley Regional Water Quality Control Board (CVRWQCB) and Division of Drinking Water and obtained an U nderground Injection Control permit from the United States Environmental Protection Agency. Pre- pilot test work
included identifying nearby supply/domestic wells, water sampling and analysis of groundwater and source water to be used for recharge, performance of aquifer tests to collect aquifer parameters a nd assess interactions within aquifer zones where nearby wells are located, and groundwater modeling analysis to evaluate the influence of injecting, storing, and extracting groundwater. Injection began on June 21, 2021, using water obtained from a nearby canal and continued until August 1, 2021. The injected water was stored for 45 days then recovered for irrigation. An approximate total of 26 million gallons of water was injected into the aquifer at an average injection rate of 800 gallons per minute. Dur ing the pilot test, Geosyntec maintained the system and collected water levels and water quality data from the injection well and nearby observation wells.

EXHIBIT 2

Notable Accomplishments
Geosyntec has provided valuable insight and advocacy for the SFKGSA towards achieving an overall program for ASR within the basin. Geosyntec was able to help the agency identify realistic goals for operation of wells and identified a key maintenance issue to be considered. The system design was critical for the startup of the test to not drag air down the well as it limits the amount of water that can be injected.

Geosyntec is currently assessing changes to the well efficiency of the irrigation well to allow adjustments in the ASR program and design appropriate operation and maint enance procedures for future ASR
operations.

• Assessment of Site Recharge Potential
• Identification of Data Gaps
Project Objective
In the preliminary assessment, Geosyntec conducted
an engineering evaluation for a potential infiltration
basin of a 60-acre parcel located near the City of Terra Bella in Tulare County. The goal of the project was to
provide Crescent Management a preliminary
assessment of the site as a groundwater recharge
facility prior to purchase of the property. Specific
objectives for the project included estimating the rate of recharge that could occur on the site and the
expected fate of the recharge water and Identifying
data gaps needed to fully assess the recharge
potential of the Site and provide recommendations for
collecting these data.

Geosyntec’s Scope of Services
Geosyntec’s scope for this project included: an initial review of available information including well logs, water level data, water quality data, and groundwater flow directions; drilling of soil borings to assess lithology and allow collec tion of soil samples for physical testing; and completion of downhole infiltration tests (within borehole) at depths anticipated for recharge basin. Physical soil testing included grain size analysis, moisture content, and permeability testing. The downhole infiltration tests were conducted by drilling to desired depth, installing well casing and placing bentonite pellets within the annular space so that water used for test cannot come back up the borehole. The test is conducted by adding water to the well casing and measuring water levels with a pressure transducer. After completion of the field program, Plot showing results of downhole infiltration test used for estimating infiltration rates of proposed basin.

Project Description
Lincoln Center is a commercial property located in Stockton, California where past operation by three dry cleaners impacted soil and groundwater with PCE on- and off-site and is located about 4 -miles south of the DTWP facility. Joe Niland (Geosyntec Senior Principal) is the Trustee named by the Federal court to oversee the assessment and remediation of the project. Through his oversight, a long-term strategy for the final remedy was develo
ped to bring the site to closure quickly and within the financial limits of the insurance policy. As part of this plan, Geosyntec evaluated existing site data and developed a hydrogeologic conceptual model that assessed : fluid migration pathw ays from the vadose zone to groundwater (infiltration); aquifer properties; groundwater flow paths and directions; groundwater quality ; and data gaps. From this assessment, Geosyntec developed an investigation plan to close the identifie d data gaps, complete the conceptual site model, and support development of the final feasibility study for remediation of the groundwater plume. The investigation included design and installation oversight of the more than a dozen groundwater monitoring, injection, and extraction wells. Following the investigation, Geosyntec tested and designed the final in-situ remediation approach in groundwater, which included pilot testing, Waste Discharge Requirement permitting, injection well system design (similar to ASR wells), and construction oversight. From this project, Geosyntec has gained valuable insights into the characteristics of the vadose zone soils and groundwater system that will be transferable to an assessment of a recharge basin at DTWP site.

Notable Accomplishments
Geosyntec also successfully negotiated permanent shutdown of the soil vapor extraction SVE system and case closure for soil source areas with the CVRWQCB using our detailed knowledge of fluid migration pathways through the vadose zone. Geosyntec currently oversees the op erations and maintenance activities of the groundwater extraction and injection system and has implemented several system optimization cost savings measures. We have implemented a cost effective and expeditious remedy that will meet budget and schedule req uirements of the stakeholders and meet the requirements of the CVRWQCB and the Federal court.

Project Objective
The Argo Drain Stormwater Best Management Practice (BMP) project is a regional stormwater BMP that is designed to comply with Santa Monica Bay Beaches Bacteria Total Maximum Daily Load (SMBBB TMDL), the 2012 Los Angeles Municipal Separate Storm Sewer System Permit, and the 2015 Industrial General Permit. The Project is located at the northwest edge of Los Angeles International Airport near the intersections of Westchester Parkway and Falmouth Avenue and will treat runoff from a 2,320 acre drainage area, consisting of commercial, residential, and industrial areas. The project is designed to demonstrate compliance specified for the applicable drainage area. The recommended Project design diverts and conveys stormwater runoff from three existing major storm drain lines to an underground infiltration facility where runoff is infiltrated into the groundwater basin underneath.

The proposed facility includes diversion structures, a pumping station, an 8.9 million gallon underground infiltration gallery, and a network of infiltration dry wells.

G
eosyntec’s Scope of Services
Geosyntec previously completed the draft 100% design in 2008. The project was put on hold following the design completion and was re-initiated in 2015. Design modifications are necessary to meet new regulatory criteria associated with the 2012 MS4 Permit and the 2015 IGP, and to account for an updated methodology for estimating compliance with the SMBB TMDL as outlined in the Santa Monica Bay Watershed J2/3 Enhanced Watershed Management Program ( EWMP). Geosyntec was contracted to acquire necessary subsurface geotechnical information; develop new design criteria based on updated regulatory and geotechnical information; perform hydrologic modeling (using EPA SWMM) and geotechnical analyses to address changes from the previous design; produce preliminary design layouts; and assist project cost estimation and project schedule development.

Notable Accomplishments
Geosyntec worked closely with the City of Los Angeles, Los Angeles World Airports, and other consulting teams to come up with a feasible, cost-effective solution to meet all design criteria within project site constraints, including minimizing interference with airfield operation during construction and operation phases, and integrating with the existing storm drain network. Modeling results indicate that the proposed facility can achieve the required capture efficiency.

d. Project Understanding
The purpose of the project is to evaluate the feasibility, provide planning, and preliminary design services related to developing a feasibility study and preliminary design report for the DWTP Groundwater Recharge Basin Improvements Project. The DWTP is located along Lower Sacramento Road north of 8 -Mile Road between the City of Stockton and the City of Lodi. The geotechnical investigations will establish the subsurface soil characteristics and evaluate if they have the likelihood of supporting a successful groundwater recharge project. The specific area that will be assessed for the project is open land to the east as depicted in the adjacent photo.

During the design phase of the DWTP, the City of S tockton Municipal Utility District (MUD) commissioned the Design-Build team to conduct a preliminary groundwater recharge feasibility study of the approximately 70-acre site adjacent to the DWTP. This draft study, completed in 2009, concluded that with available water from the Woodbridge Irrigation District (WID) and possibly City of Lodi stormwater flows, a direct groundwater recharge and recovery project was feasible and recommended additional engineering feasibility and desi gn
s
tudies to confirm water availability, recharge infiltration rates, and storage capabilities.

Proposed Approach
This section presents Geosyntec’s proposed approach for performing the Geotechnical Investigation and Hydrogeologic Characterization for the DWTP groundwater recharge improvement project. The tasks developed for this approach follow those presented in the RFP and subsequent addendums. The specific scope and approach presented within each task is based on Geosyntec’s experience both in the immediate area and performance of infiltration/recharge investigations throughout California. In addition, our proposed approach for data collection considers the full cycle of the project, including long-term and full-scale operation and maintenance, and future proposal solicitation packages to obtain grant funds for project construction.

We have also designed our proposed scope of work to follow a phased approach whereby the results of each task are assessed to determine if subsequent tasks should be revised or if enough information has been collected that indicates that the basin will not be an effective location for recharge. For example, if the results of the geophysical survey indicate that soils beneath the site are all low permeability, the subsequent drilling program may be reduced to confirm this finding, or the project can be discontinued at this stage. This approach will make sure the City does not spend unnecessary funds to complete the overall goal of the project to assess if the DWTP site is suitable for recharge.

Review of existing data for the vicinity of the DWTP Facility is key to developing an initial conceptual site model for the site and guiding the initial phases of the field programs. Geosyntec will develop a GIS geodatabase, conduct a geophysical survey and CPT program with infiltration data , complete soil borings with continuous cores for detailed lithologic analysis, and collect soil, groundwater, and source water samples to assess water quality and potential changes to groundwater quality from potential recharge operations, and conduct an aquifer test to assess aquifer properties . The collection of high- quality data is essential for the success of subsequent modeling to assess groundwater mounding from recharge, groundwater recovery, residence time of water between the recharge basin, dry wells, or injection wells and production wells, potential influence on the local and regional groundwater systems. These data will also provide the information needed for preliminary design layouts, operation and maintenance considerations, and estimate of probable design and construction costs. All the data collected will be uploaded to a common geodatabase to facilitate efficient incorporation into models and future design phases of the project.

Several physical parameters determine the suitability of a potential site for providing groundwater recharge benefits. Some parameters may require significant research to determine suitability or suitable methods. Not all physical parameters are important for every recharge mechanism (e.g. , the requirements for recharge Recharge Basin

EXHIBIT 2
Proposal to Provide DWTP Groundwater Recharge Improvements Project Geotechnical Investigation and Hydrogeologic Characterization Report 9 | Page
basins are different than those for in -lieu recharge or dry wells). Important physical parameters include the following:
• Hydraulic conductivity (vertical and horizontal) of the vadose-zone and aquifer • Depth to groundwater and fluctuation of depth to groundwater • Groundwater storage capacity
• Chemical properties of the soil, vadose-zone, and aquifer materials • Chemical properties of the water available for recharge and receiving groundwater.

Each of these parameters with respect to the Site will be assessed for this project as discussed for the tasks presented below. In addition to the above parameters, existing and historical land use, and production wells in the vicinity are important for consideration in the evaluation of feasibility and design of recharge.

As discussed in the RFP, the City of Stockton is requesting analysis for a recharge basin using Delta Water as the source water for infiltration. In addition, our investigation will include assessment of other recharge mechanisms such as dry wells, aquifer storage and recovery wells, and combinations of technologies. Our anticipated scope of work for the overall project is based on our initial review of readily available information as discussed in the following sections.

Preliminary Hydrogeologic Conceptual Model
The project site is within the Bear Creek interfan area between the Mokelumne and Calaveras River alluvial fans. The Eastern San Joaquin Groundwater Sustainability Plan ( GSP) reports that the interfan soils generally have well-developed profiles, medium-to-heavy textures, fairly well-compacted subsoils, and local hardpan that overlies silty to silty clay loams. Consequently, the interfan soils generally have low infiltration rates (less than 0.6 inches per hour).

Figure 3-14 from the GSP shows the modified Soil Agricultural Groundwater Banking Index (SAGBI). This index provides a composite evaluation of soil suitability to accommodate groundwater recharge while maintaining healthy soils, crops, and a clean groundwater supply. The SAGBI is based on five major factors that are critical to successful agricultural groundwater banking: deep percolation, root zone residence time, topography, chemical limitations, and soil surface condition. However, a limitation of this index is that it only assesses soils within the top 5 to 10 feet. To account for this limitation, the modified SAGBI map (shown below) includes an assumption that all soils with restrictive layers in the upper couple feet are modified by deep tillage. Even with the assumption of deep tillage, the map suggests that soils in the vicinity of the DWTP Figure 3 -14 from GSP showing
SGAGBI mod ified map for Site
area.

EXHIBIT 2
Proposal to Provide DWTP Groundwater Recharge Improvements Project Geotechnical Investigation and Hydrogeologic Characterization Report 10 | Page
are poor for accommodating groundwater recharge.

Note, however, that the regional map shows soils with
excellent groundwater banking potential not far to the
north of the DWTP location.

As stated in the RFP, infiltration testing conducted at the Site in 2009 concluded that a direct groundwater
recharge and recovery project was feasible with a
preliminary infiltration rate of 0.8 acre -feet per day.

However, the speci fic area and depth of the infiltration tests were not provided in the report describing this
information. Geosyntec has reviewed several boring
logs in the vicinity of the Site. Based on these boring logs a cross-section (adjacent) shows intervals of san d and gravel that are likely present beneath the Site that are conducive for recharge. However, these permeable
zones may be at depths that will require more than deep tillage to access. Accordingly, based on the results of the characterization, Geosyntec will consider engineered
alternatives to a recharge basin such as shallow wells
(“dry wells”) or trenches.

The cross -section also suggests that there may be a
good pathway for recharge water to reach the underlying water table. Based on a hydrograph (below) for a nearby well in the DWR’s Water Data Library, the depth of the
water table beneath the DWTP facility is approximately
60 feet. Based on data presented in the Eastern San
Joaquin GSP and other documents in the area, transmissivity (T) of the underlying aquifer is 4,100 to 5.000 feet
2/day. In wells with T values greater than 1,300 ft 2/day, the production yields are typically sufficient for industrial, municipal, or irrigation use indicating that the underlying aquifer has the capacity to allow storage of recharged water.

Vertical hydraulic conductivity of the soil beneath the recharge basin and of the alluvial sediments in the upper 50 feet are a key constraint on the percolation rates that are feasible for the basin. Consequently, Geosyntec’s proposed scope of work includes a feasibility evaluation of a network of shallow percolation wells (sometimes called “dry wells”) or system of trenches to enhance the recharge rate at the DWTP facility.

Geosyntec staff are experts in the design of dry wells and are w orking with the California State Water Resources Control Board to develop the permit requirements for these types of recharge facilities.

Although additional assessments are required, a cursory review of California’s GeoTracker database suggests the g roundwater beneath the Site has not been impacted with volatile organic compounds or pesticides, but there might be some elevated nitrate concentrations in the area. Water quality data obtained from DWR’s Water Data Library for wells near the Site with reported depths less than 200 feet BGS indicate that water quality beneath the Site is of good quality with the average total dissolved solids (TDS) values below 500 milligrams per liter. These data also indicate a calcium-bicarbonate to sodium-bicarbonate water type for the upper aquifer . Calcium-bicarbonate is typical of shallow fresh groundwaters, and sodium- bicarbonate is typical of groundwater influenced by ion exchange processes. This type of data assessment will be critical for assessing how recharge water may interact with the underlying groundwater.

Task 1 – Project Management and Review of Groundwater Subbasin Data Project Management
Geosyntec’s project manager, Joe Turner , PG, CHG, will develop an internal project management plan (PMP) as a guide t o monitor project performance. The plan will document critical success factors, a work breakdown structure (WBS), milestones, key deliverable dates, task budgets, and a project schedule. Joe has managed several recharge assessments including the assessment and construction of recharge basin at the Kiefer Landfill in Sacramento and the $1.6M Lower Tuscan Aquifer Monitoring, Recharge, and Data Management Project. He was also the Senior Principal Hydrogeologist for the ASR project conducted for the South Fork Ki ngs Groundwater Sustainability Agency. The approach described below is based on the successful administration of these projects.

Cost Management
Budget procedures, reports , and the baseline budget will be included in the project budget management section of the PMP. Geosyntec’s Project Manager Dashboard provides a detailed view of project financials and helps monitor and control the project by providing near real-time project data. The system will also help Joe confirm invoice accuracy. Each invoice will sh ow how the budget is managed month- to-month and will be structured to match the tasks presented in the approved agreement.

Managing Risks
Geosyntec will coordinate with the City project team to identify risks and develop mitigation measures to better control the outcome of the project. This assessment will be a guide to help the project team to detect and mitigate risks.

Quality Assurance/Quality Control (QA/QC)
Geosyntec has established QA/QC procedures that require review of calculations and deliverables by senior professionals. The PMP will include a Quality Management Plan (QMP) which will provide a road map for meeting your quality expectations. By integrating planning and tracking tools with major project requirements, ongoing interaction and guidance by company experts will facilitate program delivery that is on time, within budget, and at a level of quality that meets the City’s expectations.

Joe Turner will work closely with the City for the duration of the project and resolve potential changes in scope. Any suggested or requested changes to the scope of work derived through meetings or other communications with our team will be communicated promptly to the City. Joe will also work with the team and expeditiously discuss and propose potential additional tasks that would add value to the project.

Status Reports
Geosyntec will provide the City with written progress reports as part of the monthly invoicing to communicate progress, issues, changes, and deliverable status. In addition, Geosyntec will a lso maintain open and frequent communication with the City. This approach will provide an efficient use of resources for successful project execution and will help the City to inform other stakeholders on the progress of the project.

EXHIBIT 2

Data Review and Compilation
Geosyntec will conduct a literature search and file
review to compile information on hydrogeology in the
vicinity of the DWTP including aquifer characteristics, existing production well and groundwater monitoring
locations, groundwater elevations , g roundwater flow
directions, and groundwater quality. Geosyntec will use this information to plan the geotechnical and
hydrogeologic approach and site groundwater
recharge and rec overy evaluation. As discussed on
page 6 of this proposal, Geosyntec team member s
have worked extensively at the nearby Lincoln Center
facility (4-miles south of DWTP) and have developed
detailed conceptual and geologic site models that will
be instrumental in developing the initial conceptual site model for the study area. Other information that will be assessed includes, the following:
• Eastern San Joaquin County Groundwater
Authority GSP (2019)
• Department of Water Resources California Statewide Groundwater Elevation Monitoring (CASGEM) Program
• SGMA Data Viewer
• DWR’s Water Data Library
• California State Water Resources Control Board GeoTracker database • California Department of Toxic Substances Envirostor database • USGS Groundwater Ambient and Monitoring and Assessment (GAMA) Program • Eastern San Joaquin Data Management System
• SAGBI Data for the Site Vicinity
• California Natural Resource Agency (CNRA) Well Completion Report Map Application In addition to the Lincoln Center Facility, known facilities that have public records on Geotracker and Envirostor within the study area include the ass ociated facilities with the Lodi Plume and several leaking underground fuel sites. Many of the publically available files for these sites could have information regarding soil and aquifer properties that can be used for the assessment of the hydrogeologic properties of the general vicinity of the DWTP Facility.

Geosyntec will document the results of the literature search and review in a Technical Memorandum (TM) that will include the initial conceptual site model and focus on assessing how a groundwater rec harge and recovery operation may affect local groundwater conditions and production wells in the vicinity of the DWTP facility. The TM will also identify data gaps needed for assessment of the recharge potential of the Site.

These identified data gaps will form the basis of the Work Plan for Tasks 4 and 5.

Electrical resistivity profiling (ERP) measures subsurface electrical properties related to lithologic and chemical variations of the pore water. For example, fine grained silts and clays typically have lower electrical resistivities than coarser grained sands and gravel. The apparent resistivity of subsurface material is determined by transmitting electrical current into the ground through electrodes placed along a traverse and measuring the resulting voltage. The adjacent figure shows a typical profile from Turner et al (2014) for the Kiefer landfill located in Sacramento showing differences between low permeability silts and clays (blue) and coarse-grained sands and gravel (red). As seen on these figures sands and gravels form channel -like features (red) that control the migration of fluids. This information was critical in designing the infiltration basins for discharge of treated water completed by Geosyntec team members Joe Turner, Mike van den Enden, and Craig Riddle. Joe Turner, PG, CHG has completed several similar studies in northern California including assisting in the interpretation of air borne electromatic method (AEM) surveys in Butte County to assess recharge pathways and has been a speaker at two symposiums discussing the interpretation of geophysical surveys for development of hydrogeologic conceptual models for use in assessing groundwater migration pathways.

For this task, the City has requested an ERP survey using an Advanced Geosciences Inc. (AGI) SuperSting RB Resistivity/IP Earth Resistivity meter. NORCAL Geophysical Consultant s, Inc. ( NORCAL) of Cotati , California will conduct the ERP survey. NORCAL conducted the ERP survey discussed above for the Kiefer landfill and has worked with Joe Turner on several other similar projects. As specified in the RFP , data for the survey will be acquired along each transect using the dipole- dipole and s trong gradient array configuration with up to 56- electrodes. Measurements will be made at transmitter -receiver separations (n- spacings) of at least 1 through 8 using an electrode
separation (a-spacing) of 30 feet. This spacing results in a depth of detecti on of approximately 400- to 450-
feet and a length of about 1,540 feet that extends
across the entire length in the north to south direction of the proposed basin. After the initial acquisition
along the 56 -electrode array is completed, data are
acquired by rolling along each line in 14 - to 28 -
electrode increments until the total distance of each
line is reached. Data post -processing and numerical
modeling are accomplished using Earthlmager 2D to
generate 2 -dimensional (x -z) gee -electric cross-
sections of electrical resistivity along each survey line.

The survey conducted will consist of 4 transects
across the proposed recharge basin as shown in
above figure.

Prior to issuance of Addendum 3, we had included this task as part of Task 6 (now Task 7), Geotechnical Investigation, but recommended an electrode separation (a-spacing) of 15 feet as opposed to 30 feet. This spacing provides a depth of detection of approximately 200 feet as opposed to 400 feet b ut with better resolution on the shallower material. As dis cussed in the preliminary hydrogeologic model above, groundwater at the DWTP facility is approximately 60 feet below ground surface (bgs) and the upper aquifer is within the first 150 feet bgs. Based on these depths, we recommend changing the spacing to 15 feet. This change will provide better information of the shallower material and insights into infiltration pathways for recharge pathways. In addition, this higher resolution for the shallower material will allow better recommendations for locations and depths for subsequent tasks conducted in Task 7.

Deliverable:

1. Geophysical survey analysis report, including lithologic and stratigraphic data interpretation Task 4: Preliminary Geotechnical Investigation Approach and Planning Activities After City approval of the TMs prepared for Tasks 1 and 2 and geophysical report for Task 3, Geosyntec will prepare a Draft Work Plan and schedule for the approach to the geotechnical investigation that will characterize subsurface soil conditions beneath the vicinity of t he DWTP facility. The preliminary geotechnical investigation approach and planning activities will be designed to evaluate the suitability of the soil matrix and hydrogeologic properties of the subsurface. As discussed above, the specific scope of work presented in the Draft Work Plan will be based on the information and data gaps identified in the Tasks 1 and 2 TMs and the information from the ERP survey conducted for Task 3. The Draft Work Plan will be based on the Geosyntec team’s experience preparing work plans for similar types of projects.

Based on a preliminary assessment of data presented in the preliminary hydrogeologic model discussed above, Geosyntec anticipates that the Draft Work Plan will include methods and procedures for the following:

CPT borings to provide continuous profiles of
geotechnical properties including Soil Behavior Type
(SBT) indices. In addition, pore-dissipation testing
(PPDT) will be conducted at selected depths to provide
calculations of hydraulic conductivity (K) . The pore-
dissipation test should provide more accurate local
measurements of K that will be used to calibrate the
profile of K values calculated from the SBT data. The
adjacent figure is an example of a profile at a CPT
boring calculated from normalized SBT indices that also includes several K values based on the PPDTs.

Installation of soil borings and monitoring wells.

The Work Plan will include sampling, and logging
procedures, estimated depths, anticipated screen
intervals, and development procedures, for borings
and monitoring wells. The drilling of soil borings will be conducted in two phases. The first phase will be with
sonic drilling method to allow collection of continuous cores for preparation of detailed lithologic logs to
assess fluid migration pathways. The locations of
these soil borings will be based on the results of the
geophysical and CPT surveys discussed above.

Downhole permeability tests will be conducted within
major lithologic units identified during the CPT survey.

This method will confirm hydraulic conductivity

calculations conducted during the CPT survey and will provide valuable input parameters for hydraulic calculations and groundwater modeling.

U
sing this information in conjunction with the detailed
lithologic logs developed from the s onic core s, the
second phase will include drilling of soil borings for
installation of monitoring wells and a pumping well that will be used for aquifer testing. Alt hough currently not recommended, based on initial results of Tasks 1
through 3, it may be r ecommended to install ERT
sensors. The ERT sensors, placed at various depths,
can be used to observe the progression of the wetting
front as moisture from rain events or pilot tests of
infiltration basins passes through the subsurface and
provide similar i nformation downhole to the ERP
survey discussed in Task 3 . Scott Struck , PhD
successfully used this method to assess infiltration of water through dry wells for the Los Angeles County
Public Works. For this project, Geosyntec was teamed
with the Department of Energy’s Lawrence Berkley
National Laboratory and partnered with the United
States Bureau of Reclamation and Geological Survey.

The project was conducted to better quantify the
benefits of infiltrating stormwater.

Geosyntec anticipates installing multiple screened intervals at monitoring well locations for use as observation wells during subsequent pump tests as discussed below to assess vertical hydraulic conductivities. These wells can also be used for monitoring of mounding of groundwater and groundwater chemistry changes during infiltration pilot tests. At least one soil boring will be converted to a well that can be used as a pumping well for aquifer testing (see discussion of anticipated field program for Task 7).

Sampling of soil, groundwater, and source water. The Work Plan will include procedures and locations for samples of soil, groundwater, and the source water anticipated to be used for recharge. The Work Plan will include sampling frequency, analyte list, and QA/QC procedures. The primary objective of this testing will be to assess interactions between soils, recharge source water, and groundwater. The anticipated analytical program is discussed for Task 7 and includes soil physical properties and, chemical parameters.

After completion of the Draft Work Plan, Geosyntec will schedule a meeting with the City and other stakeholders to present the overall recommended approach. This meeting will provide the City with opportunities to ask questions prior to their review and approval of the recommended approach.

Task 6: Permits
Geosyntec will obtain all necessary permits and regulatory approval for the project. At this time, it is only anticipated that permits from the Coun ty E nvironmental Management Department to drill wells and soil borings will be required for this project.

Deliverables

1. Drilling Permits
Task 7: Geotechnical Investigation
Geosyntec will conduct the geotechnical investigation in accordance with the approved Final Work Plan. Our anticipated scope of work for this task is based on our initial review of readily available information as discussed in the preliminary hydrogeologic conceptual model provided above. As discussed in our project approach, we have designed our field program to follow a phased approach whereby the results of each task are assessed to determine if subsequent tasks should be revised or if enough information has been collected that indicates that the basin will not be an effective location for recharge. For example, for the field program, if the results of the CPT survey and soil boring program indicate that soils beneath the site are not conducive to a recharge pr ogram, it may be recommended that the subsequent program for installation of wells and performance of aquifer test not be conducted, and the project could be discontinued at this stage Proposed Scope of Work
Based on our compilation and review of existing data as discussed above, our anticipated scope of work includes performance of a C PT program, drilling and sampling of t wo soil borings, drilling sampling and installation of one nested (multiple well screens in one soil boring) monitoring well and one well used for aquifer test, performance of aquifer test, and physical and chemical testing of soil, groundwater, and source water samples. Each item is discussed below. The actual scope of work will be as approved by the City in the Final Work Plan. Fieldwork will be under the supervision of a California Professional Geologist and Certified Hydrogeologist.

Field Setup Coordination
This task includes coordinating with subcontractors, obtaining necessary field supplies and preparation of site-specific field safety plan for use by the Geosyntec team, and marking Site for clearance of utilitie s by USA. The task also includes a site visit to discuss the overall project with City personnel and mark locations for the USA utility clearance.

CPT Survey
The CPT borings will provide data on the geotechnical
properties of the subsurface including continuous profiles of SBT indices, and pore-pressure dissipation testing. The anticipated locations are shown on the adjacent figure that includes four CPT points. The actual locations may be
modified based on the results of the geophy sical survey.

This figure also shows the locations of anticipated soil borings at the Site.

For each CPT boring, pore- pressure dissipation tests will be conducted at approximately 6 depths. To assess the
infiltration rates at various depths, v alues of hydraulic conductivity K w ill be calculated from the SBT data to provide detailed trends of stratigraphic variation of K.

However, the pore-dissipation test should provide more accurate local measurements of K that will be used to calibrate the profile of K values calculated from t he SBT data. An example of a profile at a CPT boring Anticipated Locations of CPT and soil borings
EXHIBIT 2
Proposal to Provide DWTP Groundwater Recharge Improvements Project Geotechnical Investigation and Hydrogeologic Characterization Report 18 | Page
calculated from normalized SBT indices that also includes several K values based on Pore -Pressure Dissipation Test (PPDT) values was illustrated in discussion for Task 4.

Soil Borings
As shown on the p revious page, two soil borings
are proposed. The actual location of these soil
borings may be modified based on the results of the
geophysical and CPT surveys. The soil borings will
be drilled using the sonic boring method that allows
collection of a continuous core sample. These
cores will be logged by the on- site geologist
proficient in the methods described by ASTM
D2488-84 and reviewed by a California
Professional Geologist and Certified
Hydrogeologist. The boring logs will provid e
detailed lithologic profiles that will be used to
prepare stratigraphic cross -sections. At selected
depths, during the drilling of these soil borings,
down-hole permeability tests will be conducted.

These tests will allow assessment of infiltration rates within the major material types encountered at the Site and will also allow verification of the results provided by the CPT survey. Tests will be conducted by advancing the outer casing of sonic drill stem to the desired depth. A pressure transducer will then be lowered down the drill stem and programmed to record water levels at 10 to 15 second intervals. The drill stem will then be filled with water then allowed to infiltrate into the desired materials. Infiltration rates are then calculated by the slope of the line developed during this process as shown on the adjacent figure produced for a down-hole permeability test conducted at the Terra Bella, California Site.

Well Installation
Geosyntec anticipates that one soil boring will be drilled for installation of a monitoring well cluster (multi-completion) at a location determined based on the results of the above investigations. The well would consist of three 2-inch-diameter casings with 5-foot screened intervals (e.g., 60 to 70 feet BGS, 75 to 85 feet BGS, and 95 to 100 feet BGS).

Based on cost, logistics, and access issues, the monitoring cluster may be constructed in a single boring or in separate borings. Actual screened intervals will be based on results of the geophysical and CPT surveys and soil boring programs discussed above and observations during drilling of these soil borings. The monitoring well will facilitate collection of groundwater samples for water quality testing and will also be used as an observation well for the aquifer test described below. This well can also be used for assessment of mounding during any subsequent pilot tests of infiltration and potential long-term recharge operations.

An additional well will be installed that will be used to conduct the aquifer pumping test. This test well will be located and designed based on the results of the field testing discussed above. The test well will also allow collection of groundwater samples for comparison with samples collected from the individual depth intervals screened by the nested monitoring wells. Fol lowing development of this well , a step-drawdown test will be conducted that will provide preliminary values of T and K and determi nation of pumping rate used for the Nested monitoring well designed and
installed by proposed Project Manager Joe
Turner for the Lower Tu scan Aquifer
Recharge and Monitoring project. Wells
completed to depths of 1,000 feet BGS.

constant rate pumping test described below. This
well wi ll be scr eened over the entire i nterval
monitored by the observation well (e.g., 60 to 100)
and is anticipated to be 6-inches in diameter.

Aquifer Test
After completion of development of the observation
wells and pumping well, a constant rate pumping
test will be c onducted. The pumping r ate will be
based on the results of the step test discussed
above. It is anticipated that the constant rate test
will be 8-hours in duration, but a longer test may be
recommended based on results of the step test. To
monitor the test, vented pressure transducers will
be placed in each well within the nested monitored
well (3 total) and the pumping well. Use of vented
pressure transducers eliminates the need for
barometric corrections of the data. The transducers
will be placed in the wells during the step t est
discussed above and allowed to record water levels
at 1-hour intervals to assess regional changes to groundwater levels prior to the constant rate test.

Groundwater, Source Water, and Soil Sampling
Geosyntec anticipates that approximately 6 soil samples will be collected from each of the cored soil borings:
3 samples from the vadose zone and 3 samples from the saturated zone.

The actual sample depths will be based on specific conditions observed while drilling each boring with the objective of obtaining samples of both coarse- and fine-grained horizons.

Each soil sample will be analyzed for:
• Grain-size distribution (sieve analysis)
• Atterberg limits
• Moisture content
• Electrical conductivity
• Metals
• Cations and anions
• Total organic carbon (TOC)
If the resul ts of the literature search discussed for Tasks 1 and 2 indicates potential for environmental impacts, other constituents such as pesticides and volatile organic compounds may be added to the list.

Geosyntec anticipates collection of grab groundwater samples near the total depth of each of the t wo soil borings, two additional grab water samples each will also be collected from relatively permeable depths in three of the CPT points based on observations in the field, and one sample from each screen interval of the nested monitoring well and from the pumping test well collected after development. In addition, we propose to collect and analyze two samples of the potential source water for recharge: one at the beginning of the field investigation program and one at the end.

lectrical conductivity, oxidation/reduction potential, dissolved oxygen, and pH will be collected as field parameters during collection of grab groundwater samples. Additional analytes may be added based on results of Tasks 1 and 2.

Task 8: Hydrogeologic Characterization
The Geosyntec team will characterize the hydrogeology of the vicinity of the DWTP. This assessment will include documentation of our calculations and estimation of:
• Percolation rate and migration pathways
• Specific yield
• Hydraulic conductivity
• Available storage
• Recovery well production rates, and recommended location and number of recovery wells • Groundwater flow directions
• Existing groundwater quality
• Potential chemical interactions between source water, soils, and groundwater.

Geosyntec will develop a thre e-dimensional groundwater flow model as a tool to evaluate the recharge capacity and engineering alternatives to optimize recharge and recovery. The model properties will be based on information from the ESJ Water Resources Model (ESJWRM, Woodard & Curran, 2018, Appendix 2-A, ESJ Groundwater Authority, 2019) with refinements based on site -specific data including lithologic logs of boring, aquifer testing data, and well information in the vicinity. The model grid will be designed with sufficient resolution of hydraulic gradients and groundwater mounding associated with simulated recharge from the basin engineered recharge alternatives such as shallow wells and trenches.

Geosyntec will use the model to evaluate and compare engineering alternatives including:
• a recharge basin,
• a network of percolation wells,
• a network of trenches,
• injection wells, and
• r
ecovery wells.

The model simulations will provide calculations of:
• groundwater mounding,
• flow directions,
• percolation rates from a recharge basin, percolation wells, or trenches, • i
njection rates,
• recovery well production rates,
• travel time of groundwater between the recharge facility and production wells, and • percentage of recycled water pumped by production wells.

Task 9 Feasibility Report
After completion of Task 8, Geosyntec will prepare a Groundwater Recharge and Recovery Project Feasibility Report that will include the compiled results of the geotechnical investigation (Task 7) and hydrogeologic characterization (Task 8). This report will provide the following information:
• Suitability to recharge surface-applied water in terms of feet per day over the site and an estimate of the annual quantity of water capable of being recharged to the underlying groundwater basin. • Potential for groundwater recovery in terms of millions of gallons per day or acre-feet per year • Recommendation for monitoring groundwater movement to determine the volume of water recharged and av
ailable for recovery without negatively impacting the groundwater basin and/or nearby private (
or public) wells
• Potential Impacts to groundwater quality related to recharge operations • Preliminary basin layout that considers the existing surface water delivery locations and how water is best distributed and managed across the site
• Environmental clearance requirements
• Permitting requirements
• Operation and maintenance recommendations
• Estimate of probable design and construction cost
The report will also provide recommendations for performance of pilot tests for the preliminary basin outlet, and, if applicable, engineered alternatives including dry wells and trenches that could enhance the performance of recharge. The information provided in the report will be formatted so that it can be used as part of package for obtaining grant funding such as grants for SGMA implementation.

He indicated that the recharge rates assigned to the model were unusually high and that because precipitation mainly replenishes the shallow aquifer, the potential for depletion of the deeper aquifer in which the pumping occurs is a concern.

Regulatory Compliance, Former Retail Site, JR Simplot, Wasco, CA Project Manager/PG for investigation, remediation, and reporting of agricultural chemicals in soil vapor and groundwater at a 1-acre site. Soil assessments revealed subsurface soil and soil vapor impacts of 1,2,3- trichloropropane, 1,2- dichloropropane, and 1,2-dibromo-3-chloropropane to 250 feet deep. Two soil vapor extraction (SVE) systems were installed and were monitored monthly under an air permit issued by the Air Pollution Control District. Reports were prepared and submitted annually. Media from the SVE system was treated with granular activated carbon. Groundwater was monitored quarterly and was impacted with agricultural chemicals above background levels. Groundwater quarterly reports were submitted to the Regional Water Quality Control Board. Due to extensive pumping in the area, the aquifer beneath the site went from confined to unconfined, creating a natural subsurface vacuum resulting in downward migration of contamination. The SVE system was optimized to counteract this phenomenon. Surface soil was impacted with metals and pesticides; concrete capping was implemented as an interim mitigation measure.

olorado Regulation 85 Nutrient Data Gap Analysis, Colorado Stormwater Council and Urban Drainage Flood Control District, Denver, CO
For Municipal Separate Storm Sewer Systems and Colorado Discharge Permit System permittees, Regulation 85 requires public education and outreach on stormwater impacts associated with nutrients, pollution prevention/good housekeeping for municipal operations, and data collection regarding the approximate nitrogen and phosphorus contribution to state waters due to discharges from MS4s. The project determined whether adequate information exists to allow for determinations of representative nutrient estimates by statistically evaluating Front Range municipal data collected in the past. In this way, future data collection can be focused on areas that have a paucity of data to address the remaining information requirements under Regulation 85. Dr. Struck was project manager for Geosyntec.

Career Summary
Mason Albrecht has 14 years of experience implementing projects for the environmental remediation and water resources sectors. Mason has broad based project experience in site investigation, remediation, treatment system design, civil design, construction management, and operation and maintenance (O&M).

Relevant Project Experience
Engineering Consulting and Operation and Maintenance for CERCLA site, Aerojet Rocketdyne, Rancho Cordova, CA
Mason currently serves as the task manager and lead project engineer for engineering, O&M, and permit compliance support for several groundwater extraction and treatment (GET) systems that address a regional perchlorate, N- Nitrosodimethylamine (NDMA), and a volatile organic compounds (VOC) plume associated with former rocket manufacturing operations. He and the team developed O&M manuals for the GET systems with a detailed matrix of GET system parts and equipment inventory; description of component criticality and failure analysis; and maintenance checklists and procedures. The O&M manuals are a practical maintenance tool to be used by GET system operators. The purpose of the revised O&M protocols is to improve operational efficiency, reduce the risk of release of contaminants to the environment, and reduce non-routine O&M costs. Mason’s team has completed several engineering evaluations for the GET systems to improve treatment effectiveness and reduce O&M costs. For example, the team performed evaluations of several alternatives for water treatment and operations modifications to manage perchlorate in groundwater at two of the GET systems. The team also evaluated alternatives for management of biofouling in GET system extraction wells to reduce fouling of influent bag filters and O&M costs. Mason manages a complex national pollutant discharge elimination system (NPDES) discharge permit that incorporates discharge of treated water from 10 different GET systems. His support engineering staff is responsible for coordinating monthly flow monitoring, treatment system sampling, and reporting activities. This requires extensive experience with acute and chronic aquatic toxicity monitoring and toxicity reduction evaluations. The engineering staff has been able to successfully manage and coordinate several different team members while complying with the NPDES requirements, including GET system operators, sampling subcontractors, couriers, laboratories, and database managers.

orrective Active Management Unit and Stabilization for Lead Waste, Former Bryte Landfill, West Sacramento, C A Mason provided remedial action design, planning, and engineering support on this project involving waste removal, treatment and grading. The former landfill was historically used as a burn dump and is located adjacent to the existing Sacramento Bypass, which will be expanded as part of a larger flood control project for the City of Sacramento and surrounding areas. Waste in the former landfill was relocated to a corrective action management unit (CAMU) to accommodate the bypass expansion and portions of the waste with lead exceeding state and federal leaching criteria were treated with a stabilizing reagent prior to placement in the CAMU. Mason prepared the Remedial Design and Implementation Plan (RDIP), coordinated site civil design in AutoCAD Civil3D, prepared design plans and specifications, and develops cost estimates for bid procurement while also coordinating waste treatment pilot testing activities and evaluation and selection of lead stabilization reagent.

alifornia Low Threat UST Case Closure Sites, Multiple Caltrans Sites Mason provided engineering support for the evaluation of site closure for multiple Caltrans properties under the California Low-Threat UST Case Closure Policy (LTCP). As part of these evaluations, Mason updated conceptual site models (CSM) and compared current site conditions to LTCP requirements for closure. Based on the closure evaluations, he either assisted with preparing a formal request for closure or a work plan for additional site investigation/remediation.

Mason provided engineering support for preparation of work plans for pilot testing innovative remedial technologies at multiple Caltrans sites. Geosyntec is evaluating innovative technologies to help progress Caltrans sites to closure and identify those effective technologies that can be applied in full scale at similar Caltrans sites statewide.

S
oil Vapor Extraction (SVE) Systems for Chlorinated Volatile Organic Compounds (CVOC), Sacramento, CA Mason is the lead engineer for the design, installation, and O&M of SVE systems for the remediation of CVOCs in vadose zone soils at two former dry cleaner sites in Sacramento. Design responsibilities include analysis of pilot test results, developing system design parameters, well spacing and construction, system curve development, equipment selection, and plans and specifications. The pilot testing results were rigorously evaluated, compared to SVE guidance documents, and incorporated into the full-scale design. Mason’s team obtained the necessary permits from the Sacramento Metropolitan Air Quality Management District for discharge of treated vapors from the SVE system. Source testing for the permit involved analysis of vapor samples and monitoring of treatment system performance to demonstrate compliance with permitted CVOCs emissions limits. Samples of soil vapor processed through the SVE treatment system are routinely collected to evaluate CVOC mass removal and compliance with the air permit. Routine O&M activities include measurements of system process flow, vacuum, temperature, relative humidity, air permit compliance monitoring (above), inspection of mechanical equipment (e.g., positive displacement blower, motors, heat exchanger, condensate water transfer pump), and adjusting flow rates from extraction wells to optimize CVOC mass removal.

Remedial Cap for Pesticides and Metals Impacted Soils, Former San Joaquin Drum Company Site, DTSC, Bakersfield, CA
Mason currently supports the development and implementation planning for this former waste drum storage facility site managed by the California Department of Toxic Substances Control (DTSC). Mason prepared a Remedial Action Work Plan (RAW) consistent with the National Contingency Plan (NCP) and the Comprehensive Environmental Response Compensation and Liability Act (CERCLA), and the RDIP. A low permeability modified asphalt cap was selected for groundwater and human health protection from shallow soils impacted by pesticides, semi -volatile organic compounds (SVOC), and metals. The cap remedy will contain stormwater management measures that includes concrete drainage ditches, drop inlets, drain piping, and a retention basin, and involves hydrologic and hydraulic analysis per local standards. Soil and concrete sampling were performed at the site to characterize contamination in this media prior to implementation of the RAW and for the evaluation of disposal options. The analyses included the federal toxicity characteristic leaching procedure (TCLP) and the California Waste Extraction Test (WET) to evaluate the leachability and hazardous waste classification.
