Task 100-400: Wright Well Replacement
Tasks 100 through 400 are described in detail in a scope of work dated April, 1998. Task
100 consists of review of existing information and preparations of recommendations for
well location and design. This task has been completed. Remaining tasks are:
Task 200: Preparation of Well Construction Specifications
Task 300: Observation of Well Drilling and Pumping Tests
Task 400: Analysis and Reporting
Task 500: Management
Purpose: Regular meetings will be held with City staff, counsel, and other
representatives, as necessary and as directed by the City.
Description of Work: Meetings may be held in Yakima or Seattle. Materials may be
prepared to support these meetings. It is assumed that Chris Pitre will attend all of the
meetings, David Banton will attend two meetings, and that a project level Golder staff
will attend half of the meetings, as appropriate.
Deliverable: Monthly billings will be provided to the City accompanied by a brief status
report which documents progress, costs, schedule, and unanticipated project
developments and future costs. Attendance at 12 meetings including supporting materials
will be provided.
Schedule: This task will be on-going for the duration of the project.
Cost: Total estimated cost for this task is $18,048.
Task 600: Water Level Monitoring Program
Purpose: A reliable record of water levels in the aquifer system is necessary to predict
and evaluate the impacts, including benefits, of any water resource management
approach. Some of this information is, in turn, required for permitting. New monitoring
points will complement current monitoring points that the City maintains in the
production wells.
Description of Work: Between ten and 15 existing wells will be selected for installation
of transducers and dataloggers to monitor groundwater levels. Existing wells (e.g., the
Wright Avenue well) will be selected to avoid well installation costs. Both City wells
and private wells will be considered. Shallow, deep, and intermediate depth wells will be
selected with the purpose of developing a three-dimensional monitoring network.
Golder Associates
June 21, 1999
983-1085
Field visits to the selected points will be made to ascertain the physical condition of the
wellheads, to determine whether any retrofitting is necessary, and to arrange for adequate
protection measures for installed equipment. Specifications for subcontractor services for
retrofitting of wellheads and installation structures to protect installed equipment will be
prepared, and cost bids solicited. Golder will retain the services of a subcontractor based
on experience, capabilities, and bid price. Golder personnel will provide oversight of
subcontractor field services. It is assumed that approximately half of the monitoring
points will have to be retrofitted by a subcontractor to provide equipment access and
protection. Specifications for transducers and dataloggers will be prepared, and the
equipment will ordered and installed.
Additional points may be identified for instrumentation in the future as additional data
needs and opportunities are identified. Installation of these additional monitoring points
is outside the scope of this phase of the project. Two monthly data downloads, and one
quarterly analysis of data are included in this scope of work, however, the monitoring
network could remain active for many years.
Historical groundwater level information will also be compiled from City of Yakima,
United States Geological, and other sources. It is assumed that information will be
provided to Golder by the City, and that information available over the internet will be
used.
Schedule: It is assumed that it will take one month to select the monitoring points, and
two months to retrofit the wellheads with a subcontractor and install the monitoring
equipment. Assuming authorization to proceed in July, 1999, the water level monitoring
equipment should be installed by October, 1999. Data downloads will be conducted at
the end of November, 1999, and at the end of December, 1999 or the beginning of
January, 2000. A quarterly report will be prepared by the end of January, 2000.
Deliverable: A three-ring binder will be compiled containing documentation of each
monitoring point including as -built sketches, equipment specifications, set-up parameters,
photographs of the installation, and a location map. A quarterly report will be prepared
containing a hardcopy description of trends, significant anomalies, and plots of water
levels at teach of the monitoring points. An electronic copy of the water level database
will also be included.
Cost: Total estimated costs for this task is $66,743. Engineering fees of $32,695 are
based on:
➢ Two days selecting monitoring points;
➢ Two days doing a reconnaissance field visit of selected sites;
➢ One day developing bid specifications for water level monitoring equipment and
obtaining bid prices;
➢ Two days developing bid- specifications for subcontractor services, and making
contracting arrangements;
Golder Associates
June 21, 1999
4 983-1085
> Ten days in the field providing oversight of subcontractor work and installing
equipment;
> Four days for two data downloadings;
➢ One week compiling historical information from City and other sources; and,
➢ One week for quarterly data analysis and reporting.
Budgeting assumes eight-hour office days, and 12 -hour -field days.- Expenses of
approximately $34,000 cover equipment purchase and estimated subcontractor fees.
These costs are subject to the actual number of monitoring points instrumented, and
equipment and subcontractor bid prices. Obtaining access and permission to use private
wells is not included in this task.
Task 700: Hydrogeological Characterization
Purpose: An understanding of the effects that conducting an ASR program will have on
the natural system is necessary for both logistical considerations of providing a secure
municipal water supply, and regulatory reasons. A reliable quantification of the amount
of water that can be stored in the aquifer system and recovered for later use is needed.
Also needed is information on the delineation of aquifer zones.
A hydrogeological characterization of the Ellensberg Formation will be conducted to
identify aquifer zones to the extent possible based on existing information such as
Ecology well logs. The information will be used to develop and permit an ASR pilot test,
and support any necessary change applications related to relocation of the Wright Avenue
Well.
Description of Work: Well logs from the area where the Ellensberg Formation exists
within the Ahtanum-Moxee Valley will be obtained from Ecology files. East -west
geologic cross-sections spanning the Yakima River and encompassing the entire
Ellensberg Formation within the Ahtanum-Moxee Valley will be compiled. Well logs
will also be used to identify aquifer zones within the Ellensberg Formation. The
overlying Alluvial Deposits and underlying basalt aquifers will also be included in
stratigraphic interpretations.
Three City wells will be considered for use in ASR pilot testing: Airport Well, Kissel
Well, and the Kiwanis Well. One of these wells will selected by the City and Golder for
ASR pilot testing.
Once a well is selected, aquifer buildup of water pressure and aquifer response to
recharge scenarios will be predicted using analytical techniques. Recharge rates for ASR
testing will be identified. Monitoring requirements of water levels and flow rates for
ASR pilot scale testing will be defined. If a shallow monitoring well is not available in
the vicinity of the selected well, it may be recommended that one be installed to monitor
the performance of the pilot testing. Beneficial and other impacts, if any, on surface
water flows and other water rights will be qualitatively assessed.
Golder Associates
June 21, 1999 5 983-1085
Wellhead protection issues will be addressed by commissioning a search of agency
databases (e.g., Environmental Protection Agency [EPA] and Ecology registered
contaminated sites, Resource Conservation and Recovery Act [RCRA] registered sites,
etc.). Relevant agency personnel -(EPA, Ecology, Yakima County) will be contacted to
identify any sites that they are aware of that may be of concern. Work commissioned by
Yakima County will be reviewed and incorporated as appropriate.
Schedule: This task will completed in September, 1999.
Deliverable:. The findings of this task will be incorporated as an appendix in the ASR
Pilot Test Plan prepared under Task 1000. A separate report will be compiled for
necessary changes to existing City water rights for use at the replacement Wright Well.
Cost: Total estimated cost for this task is $23,547.
Task 800: Water Quality Analysis
Purpose: Water quality analysis is necessary to establish a baseline against which to
assess water quality changes resulting from reaction of recharged water with native
aquifer water, and the aquifer matrix.
Description of Work: Water chemistry of surface water and groundwater, and aquifer
material composition data will be collected. Available information from existing sources
will be collected. Water quality data as part of the City's water quality monitoring
program will be used. Information will be collected from the United States Geological
Survey and other sources on water quality and aquifer material composition. For
parameters that are not now available, water samples will be collected from the City's
Rowe Hill water treatment plant and the selected recharge well, and analyzed.
Once this information is collected, a computer model developed by the USGS
(PHREEQECi) will be used to predict reactions that may occur. These modeling runs
will provide a basis upon which to design water quality monitoring during the pilot test
and to determine whether special conditioning of the recharged water is necessary.
Schedule: This task will completed in September, 1999.
Deliverable: The findings of this task will be incorporated as an appendix in the ASR
Pilot Test Plan prepared under Task 1000.
Cost: Total estimated costs for this task is $14,359. This budget includes two days in
the field to collect water samples. 'It is assumed that $2,000 will be used for laboratory
analysis. .
Golder Associates
June 21, 1999 6 983-1085
Task 900: Engineering Modifications for ASR Pilot Test
Purpose: Retrofitting of the selected pilot recharge well may be necessary. Golder will
review the existing infrastructure and estimated flow requirements based on the
hydrogeology and well hydraulics and provide specifications for retrofitting the well for
ASR pilot testing.
Description of Work: As-builts of the existing distribution system, and the well (i.e.,
pump and valve specifications, or manufacturer's data sheets) of the selected recharge
well, will be provided by the City to Golder. Golder will identify any changes to the
existing wellhead configuration that may be needed to allow recharge of water at a
specified rate, and monitoring of water levels in the well. Changes may include:
modifications to the pump if its impellers are not designed to rotate in reverse as may
occur during recharge; disabling of check valves; installation of a water level monitoring
port; installation of meters; and other considerations.
This task consists only of engineering support to identify the well modifications needed.
No actual modifications are included in this task.
Schedule: This task will completed in September, 1999.
Deliverable: The findings of this task will be incorporated as an appendix in the ASR
Pilot Test Plan prepared under Task 1000.
Cost: Total estimated costs for this task is $8,905. This cost considers engineering
considerations only, and does not include implementation of the retrofit. The actual cost
of retrofitting the well is unknown at this time.
Task 1000: ASR Pilot Test Plan
Purpose: The ASR Pilot Test Plan will consist of a
guide for implementing the pilot test, as well as
supporting document for regulatory purposes.
Description of work: The test plan will include
summarizing the findings of Tasks 700, 800 and 900
regulatory considerations. Detailed findings of Tasks
as appendices.
document appropriate to use as a
for submission to Ecology as a
an executive summary, sections
above, and a section dealing with
700, 800 and 900 will be included
Schedule: This task will completed in October, 1999.
Deliverable: The findings of this task will be presented as a report including maps,
figures, cross-sections, tables, water quality data and other information.
Cost: Total estimated costs for this task is $18,799.
Golder Associates
June 21, 1999 7 983-1085
Task 1100: ASR Pilot Test Permitting
Reasoning: Compliance of conducting the ASR pilot test with a number of regulations
including the State Environmental Protection Act (SEPA), water quality standards, and
possibly other regulations may be required. Golder will provide technical support in
complying with these regulations.
Description of Work: A SEPA checklist or other necessary SEPA documentation will
be prepared on behalf of the City. Assistance will be provided to the City in drafting
correspondence with Ecology. The budget assumes that three meetings will be attended
by Golder personnel with the City, Ecology, and/or other parties. Materials supporting
these meetings will be prepared and distributed in advance of these meetings.
Schedule: This task will executed on an as needed basis, but is intended to be complete
by the end of January, 2000.
Deliverable: Golder will complete the SEPA checklist or other necessary SEPA
documentation on behalf of the City of Yakima, and assist in drafting related letters and
providing supporting documentation to applicable agencies. Materials in support of
meetings will be prepared.
Cost: The budget assumes a level of effort of 24 hours in assisting the City with
regulatory documentation (e.g., SEPA and other). The budget also supports three
meetings at 24 hours per meeting including time for preparation, travel, and meeting.
Support staff may be involved in preparation for the meetings. David Banton and Chris
Pitre will attend meetings with the City and Ecology. Total estimatedcosts for this task
is $10,740. The projected budget covers preparation of a SEPA checklist only.
Additional SEPA efforts, if any, are outside the scope of this budget.
Task 1200: ASR Pilot Testing
Purpose: An Aquifer Storage and Recovery pilot test consists of injecting water into the
ground at a constant rate for a discrete period of time (e.g., 30 days), allowing a period of
storage time (e.g., 30-90 days), and then extracting the water for a similar period of time
at a constant rate (e.g., 30 days). Water levels are monitored throughout, and water
quality samples are collected for analysis. This information is then analyzed to assess the
capacity of the aquifer for use in an ASR program, changes in water quality during the
storage period, if any, and the ability of the aquifer' to hold the water after recharge, for
recovery at a later time. Details presented belowmay change based on 'the ASR Pilot
Test Plan developed in task 1000.
Golder Associates
June 21, 1999 8 983-1085
Description of Work: The pilot test plan developed in Task 1000, as approved and
modified under Task 1100, will be used to implement the pilot test. It is assumed that the
City will implement all changes to the wellhead identified under Task 900: Engineering
Modifications for ASR Pilot Test. After completion of wellhead modifications, Golder
personnel will be present during a step -rate recharge test to determine the recharge rate
for the constant -rate recharge test. Water levels will be monitored throughout the step -
rate recharge test with pressure transducers and dataloggers.
A constant -rate recharge test will be conducted for 30 days. A maintenance schedule will
be prepared for City personnel to check flow rates twice a day to ensure the constancy of
the rate of recharge. Water level data will be collected at initiation and completion of the
constant -rate recharge test, and for final data retrieval at the end of the recovery period.
After recharge, a storage period of 30-90 days will be implemented during which water
levels will be monitored. During this period, weekly water quality samples will be
collected and analyzed to monitor the evolution of water quality during storage, and to
assess the movement of recharged water within the aquifer.
After 30-90 days of storage, a 30 -day constant -rate pumping (extraction) test will be
conducted and water levels monitored. Time -series water quality samples will be
collected during the pumping test on a pseudo log -frequency (e.g., after 1, 4, 12, and 24
hours of pumping, and after 4, 12, 24 and 30 days of pumping). This information will be
used to evaluate changes in water quality, if any, that may affect the potability of the
water, and reactions that may have occurred in the aquifer during storage.. This
information will also be useful in assessing whether the extracted water is representative
of the recharged water.
Water level recovery data will be collected after completion of the constant -rate pumping
(extraction) test.
Schedule: This task will completed in the first half of 2000 pending regulatory approval
from Ecology.
Deliverable: The findings of this task will be incorporated into the Report prepared
under Task 1300.
Cost: Total estimated costs for this task are tentatively estimated at $31,431, and are
subject to change pending preparation of the ASR Pilot Test Plan in Task 1000, as
approved and possibly modified under Task 1100. Costs are estimated based on the level
of effort shown in the detailed cost estimate provided in the attached budget tables and
include approximately $6,000 in water quality analyses. It is assumed that water level
monitoring equipment will already be installed for the selected well. If not, an additional
cost of approximately $2,000 will be needed to purchase a transducer and datalogger.
Golder Associates
June 21, 1999 9 983-1085
Task 1300: Analysis and Reporting
Description of Work: Data collected during the pilot testing will be compiled and
analyzed for the purposes of evaluating the long-term potential of using ASR. The
effects of operation of an ASR program with respect to beneficial and other potential
impacts, if any, to surface waters, and senior water rights holders will also be evaluated.
The interpretation of data will address the following:
• Aquifer properties;
• Aquifer storage capacity;
• Leakage rates from the recharge zone;
• Residence time of recharged water;
• Water quality considerations; and,
• Recommendations for future evaluation/implementation;
This report will be formatted to address the information needs of the City of Yakima, as
well as the information needs of the Washington Department of Ecology, in order to
allow evaluation of the data collected. Maps and figures will be included to allow the
quick understanding of significant and relevant information. Recommendations will be
provided on future direction of an Aquifer Storage and Recovery program.
Schedule & deliverables: A draft report will be submitted to the City within one month
of collection of all pilot. test data. A. final report will be issued within one month of
receipt of edits from the City.
Cost: Total estimated cost for this task is $20,474.

2 SCHEDULE
A schedule for ASR pilot testing is presented below. A major constraint on schedule is
that municipal surface water supply for the ASR pilot test is only anticipated .to be
available from fall through spring. The variable that may most affects this schedule is the
permitting process. However, we believe that the schedule presented is reasonable.
Schedule dates are developed assuming authorization to proceed in July, 1999.

AGENDA STATEMENT
Item No. /1
For Meeting of 8/3/99
ITEM TITLE: Resolution authorizing amendments to an existing contract with Golder Associates, Inc.
Amended contract will further provide for documentation in support of an application to transfer
existing water rights to a replacement well for the Wright Avenue Well; and for the development of
an Aquifer Storage and Recovery (ASR) Pilot Test Program. _
SUBMITTED BY: Dueane Calvin, Water/Irrigation Division Manager
Dave Brown, Water/Irrigation Division Engineer
Glenn Rice, Assistant City Manager
CONTACT PERSON/TELEPHONE: Dueane Calvin / 576-6480
SUMMARY EXPLANATION: Staff respectfully requests City Council to approve the attached resolution
authorizing the City to amend an existing contract with Golder Associates, Inc. of Redmond, Washington.
This amends the existing Wright Avenue Well replacement contract to provide documentation for an
application for transfer of existing water rights to a replacement well for the Wright Avenue Well; and for the
development of an Aquifer Storage and Recovery (ASR) Pilot Test Program, which will confirm the
technical feasibility of that strategy.
The Council Committee on Water/Irrigation met with staff and Golder representatives on the morning of
July 20th for a briefing on this matter. After the presentation several questions were raised surrounding the
water to be utilized in this program. It was explained that the water would come from the existing domestic
water rights, and that State statutes generally require the water to be treated to drinking water standards
prior to injection. The committee indicated that this was probably a prudent approach for the City to pursue
with respect to meeting needs during water short times.

STAFF RECOMMENDATION: Approve the resolution authorizing the accompanying contract
amendment to provide documentation for an application for transfer of existing water rights to a
replacement well for the Wright Avenue Well; and for the development of an Aquifer Storage and
Recovery (ASR) Pilot Test Program with Golder Associates, Inc. of Redmond, WA., and authorize
the execution of Task Order No. 2, by the Assistant City Manager.
COUNCIL ACTION:
During the course of the last year, City staff, Legal Counsel, and Golder Associates Inc have been involved
in conducting an analysis of groundwater rights held by the City of Yakima and developing strategies for
securing the future municipal water supply of the City. As a result of this work, the City is currently
considering various management options for securing future needed municipal water supply sources.
Among these options is an Aquifer Storage and Recovery (ASR) program. It is anticipated that, if
technically feasible, an ASR program may be an economically, politically and environmentally viable option
that can play an integral part in securing needed future municipal water supply for the City of Yakima.
The primary objectives of this scope of work are:
D To provide documentation to support an application to change existing water rights for use at a
replacement well for the Wright Avenue Well; and,
➢ To conduct the necessary technical analysis and permitting support to implement an ASR pilot
test in the first quarter of 2000.
This work will be completed in two phases. The first phase is to compile existing information, put in place a
groundwater resource monitoring system, and analyze available data. The first phase will generate
information needed to permit the ASR pilot study, and the information needed to support any water right
change applications for the replacement well for the Wright Well. It is proposed that this first phase be
completed within the calendar year of 1999.
The second phase will consist of an ASR pilot test early in the year 2000. This will consist of:
• Retrofitting the wellhead of the selected recharge well;
• A step -rate recharge test over one day to determine the ideal rate for the constant -rate recharge test;
• A 30 -day constant -rate recharge test;
• A storage period '
• Withdrawal of the recharged water; and,
• A recovery period.
The purpose of this Technical Work Plan is to develop the sequence of steps needed to assess the
technical feasibility of an ASR program.
The major costs associated with the technical implementation of an ASR program that are included in this
scope of work are:
• Monitoring of aquifer water levels;
• Hydrogeological characterization;
• Evaluating water quality considerations;
• Reconfiguration of valving and associated distribution plumbing; and,
• Conducting the pilot test.
Additional major costs that are not included in this scope of work include:
• Installation of additional wells (production or monitoring); and
• Computer modeling of groundwater flow
Balancing the costs of an ASR program are the benefits of added security of water supply and flexibility of
operation. Alternative water supplies are not considered to be available, and existing supplies may be
reduced. ASR is considered a technological application that could assist the City of Yakima in meeting the
obligation of providing for municipal water supply, and be accepted by stakeholders in water resources of
the Yakima Basin.
This scope of work is intended to be an extension of the existing authorized work under a contract signed
between the City of Yakima and Golder on March 2, 1998 for a replacement well for the Wright Avenue
Well. This work is provided on a time and materials basis. Any changes that would exceed the budgeted
amount for the proposed scope of work, must be authorized by the City.
