Introduction
This memorandum presents a scope of work and budget for expanding the City of
Tigard's (City) Aquifer Storage and Recovery(ASR)program. Groundwater Solutions
Ino; (GSI) is the overall project lead and will manage the hydro-related tasks. Murray
Smith and Associates(MSA) is teamed with GSI and will be the project engineer.
Specifically,MSA will be the design lead for the proposed pump station. This scope and
budget was prepared with input from both GSI and MSA.
Background
Tigard recently completed an ASR pilot test program in 2002 using City well COT-1R.
under Limited License No. 005. The City currently is using the same well to inject, store
and recover water during 2003. During this year approximately 115 million gallons
(MG) of source water(Portland Bull Run)was stored in the basalt aquifer beneath the
Canterbury site using COT-1R. This stored water is being recovered this summer at a
rate of approximately 1 million gallons per day(MGD)to meet peak summer water
demands.
Given the success-of the current ASR program, the City commissioned the GSI/MSA
team to evaluate the potential for additional ASR well sites to store.and retrieve greater
volumes of water that the.City could use to off-set peak demands. GSI/MSA presented
Scope of Work and Budget Es ,ate—Year 2003/2004 Tigard ASR Expansion Proffer- October 31.2003.
an ASR program expansion report that outlined and ranked the following five sites
suitable for ASR expansion:
• Baggenstos—Reservoir No. 5 (Ranking score 41.6)
• 10 MG Reservoir site.(Ranking score 37.6)
• Progress Menlor Reservoir(Ranking score 34.6)
• Tigard Well#3 (Ranking score 34.3)
• Canterbury Well#i (Ranking score 34.1)
The 10 MG reservoir site and the Baggenstos site were ranked highest. The expansion
report recommended installing a large-diameter ASR well at the 10 MG reservoir site.and
to simultaneously explore the Baggenstos site with a test well. Based on discussions with
the City,we understand that the City would like to move forward with the report's
recommendations,but would like to incorporate drilling a pilot hole at the 10 MG
reservoir site to minimize risks associated with drilling a full size ASR well. The tasks
necessary to achieve the goals of developing the 10 MG site and exploring the
Baggenstos site are presented in this scope of services. Specifically,the following main
tasks are presented:
➢ Task_1 —Complete necessary ASR permitting and land use permitting for the
proposed ASR system at the 10.MG site and for drilling a test well at the
Baggenstos site.
➢ Task 2.1 —Drill a 20-inch large diameter ASR production well at the 10 MG site.
The well will be first drilled using a pilot hole (12-inch to 16-inch),tested to
ensure the formation is sufficiently permeable enough to host a 1 MGD ASR
system prior to reaming and completing it as a 20-inch ASR production well.
➢ Task 2.2—Design,bid and build the 10 MG ASR pump station
➢ Task 3-Install a test well at the Baggenstos site and evaluate its suitability for
hosting another 1 MGD ASR system.
➢ Task 4—ASR Operational Support Year 2004.
Scope of Services
The following scope of services presents detailed tasks and subtasks in order to achieve
the goal of installing a 1 MGD ASR well/pump station at the 10 MG site, and also testing
the feasibility of developing another ASR system at the Baggenstos site.
Task 1 - Permitting
We have assumed that the City will assist with the,permitting effort especially related to
land use approval. In addition,we have assumed.that the City will pay for all permit,
fees. Detailed permits necessary for the project are presented below.

Scooe of Work and Budget Ea_...ate–Year 2003/2004 Tigard ASR Expansion Proiec— October 31,2003
Subtask 1.1 ASR Limited License Addendum
We will prepare an addendum to.the City's ASR Limited License No. 005 to include the
10 MG and the Baggenstos sites. This subtask will include preparing ASR well test plans
for both sites. Please note that the City's current ASR Limited License includes only
three ASR test wells. We will also explore with the Oregon Water Resources
Department(OWRD)the option of adding,potential ASR test sites beyond the three
targeted thus far: COT-1R, 10 MG site, and Baggenstos.
Subtask 1.2 Additional Project Permitting
In addition to the Limited License addendum, several other permits must be obtained for
each element of the project. These permits are described below:
❑ Well drilling at the 10 MG site and the Baggenstos site
Applicable permits for well drilling will be identified in the technical specifications for
the well drilling bid documents. The selected well drilling contractor will obtain all
permits associated with well drilling.
❑ Construction building permits- 10 MG site only
Construction building permits will be required to construct a well house and associated
facilities at the 10 MG site. As this property is within City limits,these permits will be
issued by the City of Tigard. It is anticipated that the selected construction contractor
will obtain these permits.
❑. Underground Injection Control (UIC) registration— 10 MG and Baggenstos
ASR wells
Each of the new ASR wells (1 O.MG and Baggenstos sites)will be required to be
registered under the DEQ UIC program as a Class V injection well. The registration
requires an application and fee. GSI will prepare the application for the 10 MG reservoir
site.
❑ Land use permits 10 MG site only
Land use approvals will be required to construct a well house and associated facilities at
the 10 MG site. As this property is within the City limits,these approvals will be issued
by the City of Tigard. It is anticipated that among items required for consideration within
the approval process are setbacks,building type, noise abatement,related site
improvements,access and landscaping requirements. As previously discussed,we
understand that the City will take the lead role on obtaining a land use permit for the 10
MG site. As such, our consulting team will provide a support role for this.subtask
❑ Water Rights Transfer Application—Adding 10 MG and Baggenstos wells
CADocuments and Settings\leaton\Local Settings\Temporary InterneVFiles\OLKD\GSI Contract-Exhibit 1.D0C 3
Scooe of Work and Budget E.,-..ate—Year 2003/2004 Tigard ASR Expansion Prdee.. October 31,2003
One of the recommendations presented in the ASR expansion report included adding new
ASR wells as additional points of appropriation to.the City's existing water rights.
Pumping native groundwater is the least expensive water supply alternative the City has
available. Consequently, it is in the City's best interest to first pump native groundwater
and then to utilize ASR to mitigate water level declines in the aquifer, if they occur, and
to improve water quality if that is an issue. To that end, this subtask includes adding the
new 10 MG ASR well and the Baggenstos test wells as additional points of'appropriation
to the City's existing water rights. To ensure that the City can pump native groundwater
from the 10 MG site in 2004 a water resources limited license will be submitted, since the
transfer may take the majority of 2004 to complete.
❑ Discharge permit(s) for handling short-term discharges for the 10 MG site
ASR well
A discharge permit is required for discharging water as part of normal ASR
operations (back flushing). Anticipated discharges include groundwater and source
water discharges that will require a discharge permit from the City and/or DEQ. We
have assumed that the City will take the lead for this subtask and that our team will
.play a support role.
❑ Oregon Health Division Plan Reviews— 10 MG ASR Well and Pump Station
The Oregon Department of Health Services (DHS)requires plan reviews for the proposed
ASR water supply well and the pump station. Our team will prepare the necessary permit
applications and submit it to DHS. For new wells, DHS also requires submittal of as-
builts,well test results,water quality results and plans for the design of wellhead,
improvements and connections to the water system prior to approving the use of the new
source. Our team will follow-up with DHS to ensure that the necessary data are
submitted to the agency for approving use of the City's new well.
Task 2— 10 MG ASR Facility.Design and Construction Services
ASR System Design
The basic design elements necessary for developing an ASR system at the 10 MG site
includes the following:
❑ ASR production well—prior to completing the hole by reaming it larger, an
intermediate pump test will be completed to evaluate the.well's potential yield.
❑ Wellhead improvements
❑ Water system infrastructure improvements
❑ Pump-to-waste facilities
It is anticipated that the ASR production well drilling will be constructed using the City's
current design/bid/build procurement procedures under a contractual agreement between
CADocuments and SettingsUeaton\Local Settings\Temporary Intemeffiles\OLK MI Contract-Exhibit 1.D0C 4
Scope of Work and Budget E ate—Year 2003/2004 Tigard ASR Expansion Proie, October 31.2003
the City and the well drilling contractor.. A pre-qualifications step for the well drilling
will be completed prior to bidding the project. The wellhead improvements,water
system infrastructure improvements and pump-to-waste facilities will be constructed
using the same procedures following completion of well drilling and system design.
Subtask 2.1 includes the design,bidding and construction of the ASR production well.
Subtask 2.2 includes the design,bidding and construction of the remaining elements.
These are described in grater detail below.
Key Assumptions:
➢ It is assumed that the City will prepare the contract documents and that the
consultants will prepare the technical specifications for each project element.
➢ It is assumed that the City will bid and advertise the projects.
Subtask 2.1 —ASR Production Well— IOMG site:
The conceptual design elements required for an ASR production well at the 10 MG site
are based on the hydrostratigraphy and aquifer test results from City owned wells(No. 2
and No. 4) and other wells completed in this part of Bull Mountain. The general
considerations for the well design are the casing depth,total depth of the well,use of a
liner, and the potential for corrosion as it pertains to casing and liner materials and wall
thicknesses.
To mitigate some of the risk associated with developing the 10 MG site,it recommended
that a 12- to 16-inch diameter pilot hole be drilled first and tested prior to reaming the
borehole to the target diameter of 20-inches: An intermediate airlift test,to evaluate
general aquifer performance criteria,would be completed using the pilot hole. The pilot
hole would not be reamed if hydraulic data indicate that the site will not support a 1
MGD ASR system,but instead would most likely be completed as a lower yield ASR
well or it could simply be completed as a native groundwater production well. The City
would realize an estimated 20-25%reduction in the overall drilling cost if the well were
not reamed to the target diameter.
The general steps to drill the well at the 10 MG site would include the following:
➢ Drill a 16-inch pilot hole to total depth.
➢ Complete a short-term(8 hours) airlift test to evaluate well hydraulics. Assuming
data are positive:
➢ Ream the upper borehole(0-100 feet bgs)to 24-inch, install 20-inch liner and
grout to surface
Ream lower borehole to 20-inch to total depth
➢ Install screen and casing assembly(assuming well is lined to protect pump
column).
A 14-inch to 16-inch diameter screen liner assembly may be set in the lower borehole to
prevent any potential for sloughing or collapse of the open borehole walls. Because of
the large wetted length of the production casing during ASR operations, an assessment of

corrosion potential will be conducted during the well design process to determine what
materials and wall thicknesses are appropriate for the production casing and liner
assemblies.
Subtask 2.1.1 --Well Drilling Specification and Contract Document Preparation:
Work under this subtask includes preparing contract documents and providing public
bidding and contractor selection services for the construction and installation of the

Subtask 2.1.3 --Aquifer Testing:
The purpose of the aquifer testing is to determine injection and pumping rates, injection
and pumping levels, and target storage volume. These efforts will be coordinated with
the well drilling contractor. .
Key Assumption
➢ We have assumed that City staff will assist with collecting field data during the
aquifer tests.
➢ We have also assumed that the City will buy a water quality meter ($3000),and
pay for laboratory testing directly ($2800).
Work subtasks include the following steps:
• Water Level Monitoring: Work under these subtasks includes establishing a
baseline water level monitoring network and collecting baseline groundwater
elevation data prior to the aquifer tests from up to two nearby observation wells
and the production well. Baseline data from the production well will be obtained
electronically with a pressure transducer and data logger system. Baseline data
from observation wells will be obtained by hand-level measurements.
• Step Rate Drawdown Test: Work under this subtask includes the completion of a
4-hour step drawdown test. The purpose of this test is to evaluate well
performance and to select a pumping rate for the constant rate test. The test will
consist of four 1-hour steps conducted at increasing flow rates one to two days
prior to the constant rate test. Groundwater levels will be measured in the
exploratory well using a 100-psi pressure transducer and electronic data logger.
The,step test data will be analyzed to determine well efficiency and the optimal
pumping rate for the constant rate test. The well will be allowed to recover a
minimum of approximately 12 hours after completing the step test and prior to
initiating the constant rate test.
® Constant Rate Test: This subtask includes completing a 96- to 120-hour constant
rate.aquifer test. The purpose of the constant rate well test is to impose a long.
duration stress on,the aquifer.to,evaluate aquifer productivity,boundary
conditions, and water quality conditions relevant to ASR feasibility. .Water
levels will be electronically-monitored in the well. Hand level measurements
will also be collected from the well and up to two observation wells, if suitable
candidates can be identified and accessed.

Scope of Work and Budget E:, ate—Year 2003/2004 Tigard ASR Expansion Prole. October 31,2003
It is anticipated that the total depth of an ASR test well at the site should be between
approximately 600 to 700 feet bgs. In general, the well will have a surface seal and
casing and will be drilled as a 12-inch diameter open test well unless conditions dictate
that the borehole has to be lined during aquifer testing. This task also will include
finalizing the test well location.
Subtask 3.1 -- Detailed Site Assessment:
Prior to selecting the final site for the Baggenstos test well, a more detailed survey will be
completed to determine the optimal location for the City's test well that will take into
account, local hydrogeologic conditions, available land and access,pump to waste issues
and overall proximity to the original Baggenstos site. Ideally the test well site can also
accommodate a full-scale ASR production well and pump station.
Subtask 3.2 -- Well Drilling Specification and Contract Document Preparation:
Work under this subtask includes preparing contract documents and providing public
bidding and contractor selection services for the construction and installation of the test
well. This effort anticipates using existing City procurement procedures for the selection
and procurement of the well construction contractor. More importantly the technical
specifications will be prepared as a separate schedule and will be part of the contract
document for the 10 MG drilling project(Task 2.1.1). In this way the pre-qualifications
will be a part of this phase of the project and there is a cost savings to the City in
preparing a separate schedule for this task rather than another bid package. We have
assumed a 50%reduction in effort in preparing the technical specifications for the
Baggenstos test well since they are a separate schedule. Subtask elements include the
following:
1. Prepare design criteria, technical specifications and drawings for the test well
construction suitable for competitive public bidding—this will be prepared as a
separate schedule and will be part of the contract documents prepared for the 10
- MG drilling project (Task 2.1.1). The pre-qualifications for the 10 MG site also
will apply for the Baggenstos drilling project.
2% The technical specifications will include identifying applicable permit
requirements for drilling and discharge of drilling and testing water.
3. The preparation of contract documents consistent with current City standards for
the procurement of construction contractor services.
4. Develop well drilling contractor prequalification requirements in accordance with
City codes and ordinances.
5. Discuss the project with local drilling contractors to promote interest in the
project.
6. Prepare for and attend a pre-bid conference at the test well site.
7. Provide assistance with preparing necessary addenda.
8. Attend the bid opening, review bids and prepare a letter recommending
construction contract award.

Work under this subtask includes the following elements:
1. Provide periodic field observation of drilling, well construction and development
activities. It is anticipated that well drilling,completion and development of the
well will require six to eight weeks to.complete.
2. Develop and maintain a field log during drilling by reviewing and interpreting
geologic materials collected by the contractor.
3. Develop a detailed log of the basalt stratigraphy based on visual observation and
chemical analysis of rock chip samples from selected intervals.
4. Prepare an as-built diagram of the well.
5. Assist the City staff with day-to-day administration of the drilling contract
through review of the contractors work,pay application review, and review of
requests for changes.
6. Attend a progress meeting with the City and project team.
Subtask 3.4 -- Aquifer Testing:
The purpose of the aquifer testing is to determine possible injection and pumping rates,
injection and pumping levels, and target storage volumes at this particular test site and to
assess whether or not this site is suitable for hosting a 1 MGD ASR system. These efforts
will be coordinated with the well drilling contractor.
Key Assumption
➢ We have assumed that City staff will assist with collecting field data during the
aquifer tests.
➢ We have also assumed that the City will buy a water quality meter($3000), and
pay for laboratory testing directly($2800).
Work subtasks include the following:
• Water Level Monitoring: Work under these subtasks includes establishing a
baseline water level monitoring network and collecting baseline groundwater
elevation data prior to the aquifer tests from up to two nearby observation wells
and the test well. Baseline data from the test well will be obtained electronically
with a pressure transducer and data logger system. Baseline data from
observation wells will be obtained by hand-level measurements.
• Step Rate Drawdown Test: Work under this subtask includes the completion of a
4-hour step drawdown test. The purpose of this test is:to evaluate well
performance and to select a pumping rate for the constant rate test. The test will
consist of four 1-hour steps conducted at increasing flow rates one to two days
prior to the constant rate test. Groundwater levels will be measured in the
exploratory well using a 1.00-psi pressure transducer and electronic data logger.
The step test data will be analyzed to determine well efficiency and the optimal
pumping rate for the constant rate test. The well will be allowed to recover a .

minimum of approximately 12 hours after completing the step test and prior to
initiating the constant rate test.
•. Constant Rate Test: This subtask includes completing a 96-to 120-hour constant
rate aquifer test. The purpose of the constant rate well test is to impose a long
duration stress on the aquifer to evaluate aquiferproductivity,boundary
conditions, and water quality conditions relevant to ASR feasibility. Water
levels will be electronically monitored in the well. Hand level measurements
will also be collected from the well and up to two observation wells, if suitable
candidates can be identified and accessed.
• Recovery Water Level Monitoring: This subtask includes monitoring water level
recovery in the test well and two observation wells at a minimum for up to five
days by electronic and hand-level measurement methods.
Subtask 3.5 -- Reporting:
Work under this subtask includes compiling and interpreting the test well data gathered
under the above subtasks to determine short and long-term aquifer hydraulic parameters
and to identify potential boundary conditions. The interpreted data will be used to
determine pumping and injection rates and storage volumes at the well location and the
overall feasibility of ASR at the Baggenstos site. Work under this subtask also includes a
review meeting with City staff to review the results. A brief technical memorandum
summarizing test well drilling a aquifer testing results will be prepared that will
recommend next steps for this particular site with regard to ASR expansion objectives.
Task 4—ASR Operational Support Year 2004
Subtask 4.1 —ASR Operational Support.
This task includes providing consulting services during full-scale operation at COT-1R
through 2004 and startup injection at the 10 MG site late in the year. The ASR
operations support task will include the following main activities:
• Once every other month,monitor the performance of COT-1R using water level
and flow rate data provided by the City.
• Track changes in well performance and advise the City if the current 3 week back
flushing program needs.to be modified.
• Provide brief updates to the City during the injection phase regarding well
performance and recommendations for operational changes, if warranted.

Scone of Work and Budaet!E ate—Year 2003/2004 Tigard ASR Expansion Promel October'31,2003
In general, our support will be very similar to:what we provided during 2004. Specific
activities for this task include:
• About every other moth review water level data provided by the City for
observation wells located in the basalt aquifer. Table 1 lists the wells included in
the water level monitoring program and the proposed frequency of monitoring..
We recommend that the telemetry system be modified to ensure discharge data
are recorded. In addition,we recommend that the turbidity data be plotted and
that it continue to be track by the City and our consulting team.
• Coordinate water quality samples that are to be collected by the City, and review
water quality data when results are available from the laboratory. Table 2
includes the proposed water quality-testing program and a planned sampling
schedule.
Key Budget Assumptions:
• The City will pay analytical costs directly.
• The budget does not include field equipment rentals such as water level meter,
water quality field parameter meter, or data loggers. We assume the City either
has this equipment or intends to purchase these items directly. We understand
that the City may choose to purchase additional data loggers for other well
locations that are accessible.
