This document presents a scope of work and associated fee estimate for GSI Water Solutions, Inc. (GSI) - and
our teaming partners RH2 Engineering, Inc. (RH2), INTERA, Inc. (INTERA), and Golder Associates, Inc. (Golder) -
to provide professional hydrogeologic and engineering services to the City of Pasco (City) for conducting an
aquifer storage and recovery (ASR) feasibility study. GSI and its teaming partners have developed this proposed
scope of work and fee estimate based on (1) the Water Resources Columbia River Basin Water Management
Agreement (Agreement) between the State of Washington Department of Ecology (Ecology) and the City, and (2) a
September 30, 2020 scoping meeting with the City in preparation of this scope of work.
The remainder of this proposal presents a summary of the project, the proposed scope of services, the estimated
fee, and the proposed schedule for the project.
Project Summary/Understanding
The purpose of this project is to determine the feasibility of using ASR to optimize the use of existing water rights
and to increase the sustainability and resiliency of the City's water supply to meet projected future demands
given that new source water supplies may not be available. The project will evaluate the feasibility of using and
storing off-season water available from the Columbia River and the shallow alluvial aquifer system in
groundwater storage zones beneath the City for use during the high -demand period.
The City entered into an agreement with Ecology to conduct an ASR feasibility study funded by a grant (WROCR-
1921-Pasco-00015) from Ecology's Office of the Columbia River (OCR). The scope of work summarized in the
following sections is designed to (1) identify potential groundwater storage zones suitable for ASR, (2) identify
potential constraints on the legal and physical availability of the source waters intended to be stored, (3) evaluate
the timing of source water availability and potential volume available for recharge, (4) assess the demand versus
supply needs and infrastructure capacities of the irrigation and potable water systems, (5) assess current
groundwater uses in the Pasco area and potential interference concerns with respect to ASR, and (6) rank the
feasibility of ASR development options.

Should results from this first phase of the feasibility study be favorable, the next step would be to conduct a
preliminary water quality evaluation (Task 5) using source water and groundwater quality data from readily
available sources, including nearby operational ASR projects. The purpose of the evaluation would be to evaluate
the water quality dynamics between potential source water options and groundwater. This information would be
used to further assess and rank source water options for recharge and candidate ASR sites. The results of the
water quality evaluation will be synthesized with the initial feasibility study results, and an implementation plan
with planning -level cost estimates will be developed and integrated in a final feasibility report (Task 6).
Scope of Services
This section describes the services that our team will provide the City and our estimated fee to complete these
efforts. The proposed scope of services will consist of three tasks with the option to include two potential
additional tasks:
■ Task 2 - Hydrogeologic Feasibility Assessment
■ Task 3 - Source Option Analysis
■ Task 4 - Initial Feasibility Study Report
■ Task 5 (optional) - Water Quality Evaluation
■ Task 6 (optional) - Final Reporting, Implementation Plan, and Planning Level Cost Estimates
Task 1 is reserved in the Agreement for City staff to administer the project and is not included in this scope of
services or fee estimate.
The following subsections describe the components and assumptions associated with each of the tasks listed
above. The estimated cost for each task and the total estimated project cost are provided in Table 1.
Task 2 - Hydrogeologic Feasibility Assessment
The objective of Task 2 is to investigate the hydrogeologic feasibility of using ASR to add sustainability and
resiliency to the City's water supply portfolio. Specific work activities that our team will complete as part of this
task will include:
■ Compiling and reviewing geologic map(s), hydrostratigraphic cross-sections, and results from local ASR
projects conducted in similar hydrogeologic settings
■ Summarizing the regional and local hydrogeologic setting to the extent possible using available
information, including descriptions of the hydraulic characteristics and general water quality conditions of
potential aquifer storage units
■ Estimating potential recharge rates, volumes, and durations (based on results from Task 3) and
conceptualizing ASR well designs that would be suitable to receive recharge source water
■ Assessing current groundwater uses in the Pasco area, and estimating the potential radius of influence
and potential interference concerns with respect to anticipated ASR activities
■ Summarizing primary uncertainties and data gaps and providing recommendations for addressing the
data gaps in future phases of work
■ Ranking and recommending preferred hydrogeologic settings for ASR within the City
■ Developing an ASR well prognosis that describes target aquifer storage zone(s), planned well and seal
depth(s), and anticipated casing diameter(s)
Deliverables and Milestone Activities
The primary deliverables and milestone activities for Task 2 are:
■ Technical memorandum and presentation to Ecology

comment on the draft technical memorandum.
■ One, one-hour virtual conference call with the City to discuss findings of the technical memorandum and
presentation to Ecology
■ One, one-hour virtual presentation to Ecology, including Q&A
Task 3 - Source Option Analysis
The primary objectives of Task 3 are to identify and prioritize potential source water options with respect to (1)
source water availability, (2) feasibility of acquisition, (3) potential treatment requirements pre- and post -storage,
and (4) planning -level costs to acquire and deliver to recommended ASR sites. Specific work activities that our
team will complete as part of this task will include:
■ Compiling current and future capacity analyses for both the irrigation and water systems in the next 16 -
year growth period relative to City instantaneous and annual water rights and the peak season of use,
including identification of storage volumes versus recovery volumes and periods.
■ Evaluating physical and legal constraints of current or anticipated sources of supply during off-peak
seasons.
■ Defining the constraints on when and how water can be diverted from the Columbia River associated with
water rights, environmental, and instream flows, including surface water withdrawals and City irrigation
wells assumed to be in hydraulic connectivity with the river.
■ Assessing the requirements for identifying groundwater in hydraulic continuity with Columbia River
surface water that could be diverted.

comment on the draft technical memorandum.
■ One, 1 -hour virtual conference call with the City to discuss findings of the technical memorandum and
presentation to Ecology
■ One, 1 -hour virtual presentation to Ecology, including Q&A
Task 4 - Initial Feasibility Study Report
After completing Tasks 2 and 3, our team will prepare a draft initial feasibility study report that synthesizes
results presented in the Task 2 and 3 technical memorandums (to be included as attachments). The report will
overlay the results from the source options analysis with the hydrogeologic feasibility assessment to rank and
prioritize various ASR development alternatives, and it will be the basis for assessing whether source water
availability and the hydrogeological setting in the Pasco area suggest that ASR may be feasible.
Deliverables and Milestone Activities
The primary deliverables and milestone activities for Task 4 are:

Fee Estimate and Assumptions
The estimated fee for this task is $28,000, and is based on the following assumptions:
One, 1 -hour virtual conference call with the City to discuss findings of the report and presentation to
Ecology
One, 1 -hour virtual presentation to Ecology, including Q&A
Only a single document review cycle will be necessary. GSI will incorporate City and Ecology review
comments into the report, and GSI will finalize, publish, and distribute the final report to the City and
Ecology.
GSI will submit four hardcopies of the final report: two for the City and two for Ecology, each containing
one digital version of the report (Adobe Acrobat .pdf).
Task 5 (optional) - Water Quality Evaluation
Should results from Tasks 2 thorough 4 be favorable, the next step would be to conduct a preliminary water
quality evaluation using water quality data compiled as part of Tasks 2 and 3 and from nearby operational ASR
projects. The purpose of the evaluation would be to evaluate the water quality dynamics between potential
source water options and groundwater storage aquifers. This information would be used to further assess and
rank source water options for recharge and candidate ASR development sites.
A scope of services and fee estimate for this task will be developed at a later date.
i asK a (optional) - Irina) Keporting, Implememailon Plan, and Planning Level Cost
Estimates
Results from the water quality evaluation (Task 5) will be synthesized with the initial feasibility study results, and
an implementation plan with planning -level cost estimates will be developed and integrated in a final feasibility
report.
A scope of services and fee estimate for this task will be developed at a later date.
Fee Estimate
GSI will complete this scope of work on a time and materials basis for the estimated amount of $118,000. The
fee estimate associated with this scope of work is presented in Table 1, and includes consulting team labor and
expenses and a 5 percent markup on outside services. This fee estimate will not be exceeded without prior
authorization from the City.
Schedule
We are prepared to begin working on this project immediately upon receipt of written authorization to proceed. An
anticipated project schedule including work activities and task deliverable due dates is provided in Figure I.
