Exhibit B - Scope of Services
Exhibit B to the AGREEMENT between the City of Fort Collins, Colorado, a Municipal Corporation,
hereinafter referred to as the City, and CH2M HILL Engineers, Inc., hereinafter referred to as the
Professional, for a project generally described as:
UProfessional Engineering Services to perform a fatal flaw analysis and fill in gaps in the feasibility
analysis (performed by others) to confirm the feasibility of Aquifer Storage and Recovery (ASR).
The Professional’s services for the project are detailed hereinafter.
Project Objective: To further investigate and advise the City on the feasibility of ASR based on
Professional’s independent review of the Assessment of Fort Collins’ ASR Opportunities Report
dated April 19, 2017. The ASR project is proposed to provide additional water supply, increase
drought resiliency, and provide emergency treated water storage.
It is understood the City will designate Mr. Adam Jokerst and Eileen Dornfest as the City Project
Managers (PMs) and primary points of contact with respect to the work performed under this
AGREEMENT, with authority to transmit instructions, receive information, and interpret and define
City policies and decisions relative to elements pertinent to the work covered by this AGREEMENT.
Task 1 – Storage Zone Characterization
Professional will further research and review available existing data to fill in the data gaps and
further characterize the hydrogeologic nature of the Dakota Formation including the type of
porosity exhibited by these rocks (primary, secondary, fracture, etc.), static water levels, local
pumpage, degree of confinement, effective thickness, and native groundwater quality. With this
information, Professional will evaluate the injection levels at differing rates, pressures, groundwater
migration rates, and the degree of mixing between source water and native groundwater.
Professional will coordinate with Colorado State University (CSU) staff via in person meetings and
teleconference to understand what data has already been reviewed and gathered. In the same
meeting, professional will coordinate with CSU local geology and dam experts to assist with Task 3
(see Task 5 below).
If necessary, Professional will gather additional data from online resources such as United States
Geological Society (USGS), Colorado Division of Water Resources (DWR), Colorado Oil and Gas
Conservation (COGCC), Colorado Division of Water Resources (DWR) and the Environmental
Protection Agency (EPA). Existing data review will be performed to:
• Identify recent water quality of the source water,
• Identify water quality of the potential injection zones sampled by personnel from Colorado
State University (CSU) from supply wells in area screening or open in the Dakota Formation,
• Confirm static water levels and identify groundwater gradient and l groundwater flow
directions,
• Confirm porosity and permeability for the Dakota Formation,
• Review existing injection tests, pressure buildup, injection capacity from existing UIC
permits in the area completed into the Dakota Formation.
Professional will identify data gaps and the risks associated with the missing data.

PAGE 3 OF 11
A status meeting will be held between the Professional and City to review the results of Task 1 and
identify whether additional scope tasks should be completed as a part of this fatal flaw analysis,
such as the tributary/nontributary determination, based on the results of Task 1.
Assumptions:
• No field work will be performed to complete this task.
• Recent water quality data collected by CSU from existing wells in the area will be provided
by the City.
• If static water levels were measured by CSU at the time of water quality sampling, that data
will be provided by the City.
• If additional water quality sampling is required, it will be identified and scoped later.
• The City will provide source water quality analyses.
• Up to one, three-hour meeting will be held with Professional and CSU at CSU office. Up to
three members of the Professional team will attend (two in person and one via
teleconference).

teleconference.
Deliverables:
• Meeting agenda and meeting minutes
• Data gaps will be identified in the final technical memorandum, Task 7
Task 2 – Geochemical Model
Professional will perform a preliminary geochemical evaluation to determine if the source water
quality (recharge water) is compatible with the native groundwater quality and the mineralogy of
the storage aquifer. During Task 2 the Professional will employ a geochemical equilibrium model to
investigate mineralogy of the Dakota Formation based on water quality analyses, mixing between
the source water and groundwater, and reactions between the source water and aquifer minerals.
Based on the preliminary model results, Professional will identify treatment requirements and
potential issues that may arise like as leaching of undesirable metals, precipitation of metals and
plugging, clay dispersion and swelling, and scaling.
Based on the available water quality data, Professional will identify critical missing water quality
parameters which could affect the results of the geochemical modeling and risks associated.
The water quality parameters recommended for this evaluation are included as Exhibit D.
Assumptions:
• No field work will be performed to complete this task.
• If additional water quality sampling is required, it will be identified and scoped at a later date.
• Source water quality will be provided by the City.
• Storage zone water quality and minerology data will be provided by the City and based on
recent water quality sampling performed by CSU.
Deliverables:
• Results of the preliminary geochemical evaluation will be documented in a final technical
memorandum, Task 7.

Task 3 – Induced Seismicity Risk
Professional will summarize the potential risks associated with induced seismicity resulting from
operation of the proposed ASR wellfield, particularly recharging water into confined aquifers under
positive pressure. The evaluation will include researching the following items using online sources
and input from CSU:
• Characterizing local structural geology using online resources, CSU resources, and field
mapping as needed (see Task 4),
• Identifying active or inactive faults in the area and other mesoscopic fabrics including joints,
cleavage, etc. that can influence seismicity during injection operations using online
resources, CSU resources and field mapping as needed (see Task 4),
• Identification of documented seismic occurrences in the area,
• Research and review of case histories of injection or withdrawal activities linked to induced
seismicity,
• Research and review of case histories of injection or withdrawal activities linked to dam
failure or damage, and
• A qualitative assessment of the potential for induced seismicity due to ASR activities.
Assumptions:
• All information used in the analysis will be readily available from public resources, and expert
knowledge.
Deliverables:
• Results of the induced seismicity evaluation will be documented in a final technical
memorandum, Task 7.

development that affects the scope or timing of Professional’s services, or of any defect in the
work of Professional.
3. Professional will provide the City with deliverables as defined respectively in this scope of work.
4. All deliverables will be distributed electronically via email (pdf format).
5. Meetings with the City will be held at the City’s service center office or water treatment facility.
6. In providing opinions of cost, financial analyses, economic feasibility projections, and schedules
for the project, Professional has no control over cost or price of labor and materials; unknown or
latent conditions of existing equipment or structures that may affect operation or maintenance
costs; competitive bidding procedures and market conditions; time or quality of performance by
operating personnel or third parties; and other economic and operational factors that may
materially affect the ultimate project cost or schedule. Therefore, Professional makes no
warranty that City's actual project costs, financial aspects, economic feasibility, or schedules will
not vary from Professional’s opinions, analyses, projections, or estimates. If City wishes greater
assurance as to any element of project cost, feasibility, or schedule, City will employ an
