TO:
Mayor and Members of the City Council
FROM:
Office of the City Manager
By: John Oskoui, P.E., Director of Public Works
SUBJECT:DESIGN, INSTALLATION, AND EQUIPPING OF NEW GROUNDWATER
WELLS - EXECUTE PROFESSIONAL SERVICES AGREEMENT
RECOMMENDATION
That the City Council authorize the Mayor to execute a Professional Services
Agreement with Geoscience Support Services, Inc., for the design, installation and
equipping of two new groundwater wells, for an amount of $746,058.
BACKGROUND
The City of Downey’s (City or Downey) water system presently delivers 15 million
gallons per day of groundwater to a population of approximately 111,000. Groundwater
provides customers with 100% of their potable water needs. There are a total of 20
active groundwater wells (11 additional inactive and abandoned wells) in Downey’s
water system, which can be called upon depending upon customer demand. The City
does not actively use any storage reservoirs. Instead, the City uses the aquifers within
the Central Groundwater Basin from which it pumps groundwater directly into the
potable water transmission/distribution system for delivery to its customers. These
aquifers provide for storage of groundwater essential for meeting maximum day and
peak hour demand conditions, and for firefighting and other emergencies. The
groundwater used by the City’s customers does not presently require treatment or
disinfection.
Despite the good quality of groundwater presently provided by the City, a majority of the
City’s older (constructed between the 1940s and 1950s), shallow groundwater wells are
becoming less and less responsive to rehabilitation methods such as wire brushing,
jetting, and chemical treatments resulting in large permanent reductions in groundwater
production and significantly higher energy demands. The frequency of well
maintenance has subsequently increased resulting in greater use of labor, materials
and equipment.
Many of the City’s older wells are also screened in shallower aquifers making them
susceptible to shallow aquifer contamination within and adjacent to the City. A
previously completed Groundwater Master Plan identified a good quality, low cost water
system that is aging and becoming more susceptible to future contamination.

The City recently completed a Water System Master Plan (WSMP) which among other
things provided recommendations for future water supply needs and installation of three
new groundwater wells over the next 15 years two of which are proposed to be installed
over the next 5 years.
DISCUSSION
A Request for Proposal (RFP) was issued on October 6, 2011, soliciting proposals from
qualified professional hydrogeologists and engineering consultants for the design,
installation, and equipping of two new groundwater wells for the City’s water system. In
response to the RFP, three Proposals were received on November 1, 2011.
A qualification based evaluation and selection process addressing project
understanding, experience and capabilities of project team members, project approach,
schedule, compliance with regulatory requirements, reputation, and ability to provide the
required services was performed. Based on the results of the evaluation process,
Geoscience Support Services, Inc., along with their subconsultant RBF Consulting, has
been selected as the most qualified professional services provider to complete the
necessary work for design and construction management of two new groundwater
wells.
Items to be completed as part of this groundwater well design, installation, and
equipping project include but are not limited to:
Permitting and regulatory assistance – California Environmental Quality Act
(CEQA), California Department of Public Health (DPH) Drinking Water Source
Assessment and Protection (DWSAP) documents, etc.
Site Assessments and Preliminary Design Reports (Well Installation)
Technical Plans, Specifications, and Bidding Assistance (Well Installation)
Construction Inspection and Management Services (Well Installation)
Well Completion Reports (Well Installation)
Preliminary Design Reports (Well Equipping)
Technical Plans, Specifications, and Bidding Assistance (Well Equipping)
Construction Inspection and Management Services (Well Equipping)

The project involves a multi-step process as outlined above including: permitting and
site assessments; followed by the design for the drilling and installation of the well
casing including soil, water quality, and production testing; bidding and construction of
the well casing and associated testing; design of the piping and above grade portion
(well housing, water and storm drain piping, pump/motor, electrical, security, etc.) of the
wells; and final regulatory approval before the wells can be activated and begin
producing water for delivery to City customers.
Preferred groundwater well locations at both abandoned and active City well sites in the
northeast, central, and southwest portions of the City and at the Utilities Yard were
identified as part of the WSMP through the development of a potable water hydraulic
model. However, final locations will be dependent upon the results of the siting study to
be conducted as part of the well project that will analyze aquifer production and storage
potential, groundwater quality, well interference, proximity to abandoned wells,
construction and maintenance constraints, site layout, impacts to public, proximity to
existing infrastructure, capital and maintenance costs, etc.
A copy of the Professional Services Agreement, which includes the Scope of Work,
Project Schedule, and Project Budget, is attached.
FINANCIAL IMPACT
The total cost to complete the project is $820,664 which includes $746,058 for the
negotiated Agreement and a contingency of $74,606. The Fiscal Year 2011-12 Water
Fund Capital Improvement Program budget includes sufficient funds for the $820,664
cost to complete the activities required for this project. In order to execute the
Agreement, the following amounts will need to be appropriated from the associated
Water Fund accounts:
$734,300 account number 51-1-8665-0700
$86,364 account number 51-1-8654-0700

EXHIBIT “A”
DESIGN, INSTALLATION, AND EQUIPPING OF NEW GROUNDWATER WELLS
SCOPE OF WORK
Task No. 1 – General Administration, Meetings, and Presentations
1.1 Project Kick-Off Meeting
The primary objective of the project kick-off meeting will be to meet face-to-face with key
project individuals from the City to make sure that everyone understands the intent, objectives,
tasks, budgets, schedules, milestones, and deliverables. The kick-off meeting also identifies
the individuals who are responsible for implementing each part of the work. Additionally, this
meeting provides a forum for discussion of critical path tasks such as permitting and
preliminary design, and how those tasks can be efficiently expedited. Prior to the kick-off
meeting, GEOSCIENCE will prepare a detailed project schedule and work plan. The project
work plan will consist of a simple letter report outlining project milestones, deliverables, team
responsibilities, and project execution strategies.
1.2 Project Management & Meeting Attendance
Project management will include meeting attendance, quality assurance and quality control
reviews, resource management, maintenance of the project schedule and budget, and general
administrative coordination.
In order to maintain effective communication, GEOSCIENCE will conduct monthly progress
meetings with the City to present the status of the project deliverables and to coordinate any
outstanding requirements. In addition to the kick-off meeting, GEOSCIENCE will prepare for
and attend up to twelve (12) additional meetings (inclusive of progress meetings) with City
personnel and other agencies throughout the course of the well installation and equipping
project. These meetings will include, but not be limited to, the following:
Field meeting with CDPH to further the permitting process,
Meeting to discuss the results of the preliminary well design report,
Meeting to discuss the preliminary DWSAP documents,
Study session to discuss the results of drilling and zone testing, and the proposed well
design recommendations,
Presentation of the results of well drilling, construction, development, and testing, and
Meeting to discuss the results of the preliminary design report for well equipping.
Meeting agendas will be prepared by the GEOSCIENCE team for all project meetings and
meeting minutes will be provided as necessary.
Task No. 2 – Permitting and Regulatory Assistance
The construction and equipping of the new wells will be regulated by several State and local
agencies. The GEOSCIENCE/RBF team will take the lead in permit acquisition but anticipates
that close coordination with City personnel will be required throughout the entire project. It is
assumed that direct coordination will be required between the Project Team and
Design, Installation, and Equipping of New Groundwater Wells Page 9 of 29
representatives of the appropriate permitting agencies. GEOSCIENCE will take the lead in
coordinating acquisition of the well construction permit through the drilling contractor,
coordination with CDPH’s on-site inspector, and will prepare preliminary and final DWSAP
documents. RBF’s efforts will focus on meeting CEQA compliance and obtaining the
necessary permits for temporary discharge of flows during well construction. Additionally, RBF
will also provide assistance to the City to obtain approval from CDPH for the two proposed well
sites.
2.1 Los Angeles Regional Water Quality Control Board for NPDES Discharge
Requirements
RBF will support the City to amend its existing or obtain an NPDES permit for discharge of
pump-to-waste water from each well. GEOSCIENCE will be responsible for enforcing
compliance and overseeing monitoring requirements specified by the dewatering permit.
2.2 California Department of Public Health Approval
Prior to drilling, an application for a Well Construction Permit will be required from the County
of Los Angeles Department of Public Health. The drilling contractor is expected to apply for
and pull this permit prior to start of construction. However, early coordination with the County
and CDPH is required to confirm that the location of the proposed well meets setback
requirements. RBF will prepare drawings and reports required to obtain CDPH approval for the
two well sites. Those drawings generally contain:
Plot map showing surrounding street and the well location,
50-ft. and 100-ft. influence circles,
Utilities with a 50 ft and 100 ft circumference, such as sewer lines, recycled water lines,
oil lines, and underground storage tanks.
Although not specifically required by CDPH, it is recommended that design plans of the well
equipping project be provided to CDPH for review prior to finalization. As part of this task, RBF
has budgeted for one meeting with CDPH as well as e-mail and telephone correspondence
during preliminary and final design. This task does not include required engineering reports for
amendment to the City’s well operating permit.
2.3 CEQA Compliance
RBF will prepare one IS/MND that addresses the environmental effects of well construction in
accordance with the CEQA Guidelines. This scope of work assumes that an Initial
Study/Mitigated Negative Declaration (IS/MND) will be the appropriate document to satisfy the
requirements of the California Environmental Quality Act (CEQA). RBF understands that the
project would include the construction of two groundwater wells at two of six sites identified in
the RFP. RBF assumes that each of the six candidate sites is fully developed and that no
stand alone CEQA-specific technical studies would be required. Existing documentation would
be utilized to substantiate conclusions when necessary (e.g., General Plan, General Plan EIR,
previous CEQA documentation, etc.). This scope specifically excludes the preparation of an
Environmental Impact Report (EIR) and/or the processing of environmental regulatory permits.
Tasks associated with preparation of the IS/MND are described below.
Design, Installation, and Equipping of New Groundwater Wells Page 10 of 29
A. Research and Investigation
This task consists of project research and site reconnaissance to ensure that all
reference documents and existing conditions information is current. As part of this task,
RBF will research available information, including local planning documents and
updated plans/maps via the Internet. RBF will conduct a site visit and record
representative site conditions with color photographs. This task also includes an
introductory section within the IS/MND, discussing environmental review requirements
of the project (pursuant to CEQA) and the local agency guidelines. The introduction will
include the project location, environmental setting, existing uses on-site and in the
vicinity, and the project description and relevant background/history information. The
project description will be based on available information from the City and from other
tasks described below.
B. Environmental Checklist
This section will include a summary page of project information followed by an
explanation of factors considered for potential impacts. The Initial Study Checklist will
be presented in a four-column layout, identifying impacts according to the following four
significance categories:
1) Potentially Significant,
2) Less Than Significant With Mitigation Incorporated,
3) Less Than Significant, and
4) No Impacts.
The section will provide a listing of documentation that will be incorporated by reference
and notations for all references utilized for the determination. A review of the Initial
Study Checklist will be performed to ensure consistency with the current Appendix G of
the CEQA Guidelines.
C. Environmental Analysis
The Environmental Analysis section will provide supporting information for the
conclusions rendered in the Environmental Checklist. The IS/MND will analyze all
impact categories as mandated by the CEQA Guidelines.
Aesthetics
. The IS/MND will evaluate the project’s potential aesthetic impacts,
focusing on temporary construction-related disturbances and the long-term
effects of the new well site.
Agricultural Resources
. Impacts to agricultural resources would not occur as
part of the project. However, the IS/MND will confirm existing conditions and
provide conclusions under CEQA in this regard.
Air Quality
. The primary focus of air quality analysis within the IS/MND will be
on short-term construction due to the potential proximity of residential uses to the
project site. RBF will quantify project emissions in accordance with SCAQMD
methodology, utilizing required modeling software. The air quality discussion will
also include a quantification of greenhouse gas emissions and a discussion of
global climate change under recent State legislation.
Biological Resources
. The proposed project sites are located within fully
urbanized, residential areas. It is not anticipated that impacts to biological
resources would occur as part of the project.
Design, Installation, and Equipping of New Groundwater Wells Page 11 of 29
Cultural Resources
. Due to the disturbed nature of the project areas, the
project is not anticipated to result in impacts to cultural resources. However, the
IS/MND will confirm existing conditions and provide conclusions under CEQA in
this regard.
Geology and Soils
. The IS/MND will examine the grading/excavation required
for the project, on-site and regional seismic conditions, and exposure of
people/structures to adverse seismic affects and soil characteristics (i.e.,
erosion, expansion, instability) associated with project implementation.
Hazards and Hazardous Materials
. The IS/MND will include analysis of
potential hazards and hazardous materials associated with existing operations at
the well sites, in addition to long-term operations associated with the
new/upgraded wells.
Hydrology and Water Quality
. RBF will utilize existing information and
documentation to perform its analysis of the project’s potential impacts. The
IS/MND will review the project’s affects on drainage and water quality for both
the construction process and during long-term operation and provide conclusions
under CEQA.
Land Use and Planning
. The IS/MND will analyze the project’s consistency
with the City’s General Plan and Zoning Code. This section will also examine
the project’s compatibility with existing surrounding land uses in the site vicinity.
Mineral Resources
. Impacts to mineral resources would not occur as part of
the project. However, the IS/MND will confirm existing conditions and provide
conclusions under CEQA in this regard.
Noise
. The IS/MND will analyze both short-term construction noise and overall
changes in ambient noise levels due to long-term operations of the project,
particularly due to the proximity of residential receptors to the project site.
Population and Housing
. The IS/MND will analyze the project’s potential for
growth inducement and the possibility for the project to displace housing or
people.
Public Services
. Impacts to Public Services are not anticipated. However, the
IS/MND will confirm existing conditions and provide impact analysis in this
regard.
Recreation
. It is not anticipated that the proposed project would affect the
operation of any parks or recreational facilities. However, the IS/MND will
confirm existing conditions and provide conclusions under CEQA in this regard.
Transportation and Traffic
. Since the project would generate a negligible
number of trips during long-term operations, the primary focus of this section of
the IS/MND will be on construction-related traffic. Mitigation measures will be
provided (if necessary), particularly in regards to the potential need for a
construction vehicle routing plan and/or limitations on the hours for construction
deliveries.
Utilities and Service Systems
. The project itself represents a utility
enhancement and it is not anticipated that the well site would require the use of
substantial utilities or service systems besides the consumption of electricity for
operation of groundwater pumps.
D. Initial Study Determination
This section will denote the appropriate CEQA action based upon the findings of the
Environmental Checklist/Environmental Analysis described above.
Design, Installation, and Equipping of New Groundwater Wells Page 12 of 29
E. Graphic Exhibits

(previous commenting agencies/parties, responsible public agencies, trustee agencies,
and interested parties) for City review and approval and distribute up to thirty (30)
copies of the IS/MND for public review. RBF will also post the Notice of Availability for
the Draft IS/MND at the County Clerk and send copies of the document to the State
Clearinghouse. This scope of work assumes that the City will perform any radius
mailing and/or newspaper ad posting for the project.
H. Final IS/MND
Subsequent to the CEQA-mandated public review period, the Final IS/MND shall be
prepared. This document would include the IS/MND and the Mitigation Monitoring and
Reporting Program (MMRP). RBF will submit ten (10) copies of the Final IS/MND to the
City.
1. Mitigation Monitoring and Reporting Program
To comply with Public Resources Code Section 21081.6 (AB 3180), RBF will
prepare a Draft MMRP that will be submitted to the City for review and comment.
RBF will respond to one complete set of City comments on the Draft MMRP. The
MMRP will be defined through working with staff to identify appropriate monitoring
steps and procedures in order to provide a basis for monitoring such measures
during and upon project implementation.
I. Notice of Determination
Subsequent to the adoption hearing for the IS/MND, RBF will prepare the Notice of
Determination (NOD) for the proposed project and file it with the California State
Clearinghouse and the County Clerk. This scope of work assumes that the City will be
responsible for the California Department of Fish and Game (CDFG) NOD filing fee, if
applicable.
Meetings and Coordination
Mr. Alan Ashimine will be responsible for quality control, oversight of the analysis, and the
management and supervision of the environmental review as well as consultation with the City.
Mr. Ashimine will undertake consultation and coordination of the project and review the
IS/MND for compliance with CEQA requirements. RBF will attend project meetings, will
represent the City at public hearings, and make presentations at these meetings if necessary.
This task assumes attendance at two project meetings with City staff and one public hearing.
Design, Installation, and Equipping of New Groundwater Wells Page 13 of 29
Additional meetings shall be billed on a Time and Materials basis.
Deliverables
Deliverables provided by RBF according to the environmental services work program
described above would include the following:
Six (6) copies of the Screencheck Draft IS/MND;
Three (3) copies of the final “Check” Draft IS/MND;
Thirty (30) copies of the Public Review IS/MND; and
Ten (10) copies of the Final IS/MND.
2.4 City of Downey Planning and Building and Safety Plan Check
During preliminary design, RBF will meet with the City to identify requirements from its planning
and building and safety departments for the proposed buildings. Based upon this coordination,
RBF will prepare schematic architectural elevations showing the proposed buildings. It is
assumed that both sites will have buildings that will house the wellhead, electrical, and
disinfection equipment. If required, RBF will attend two meetings with the City’s planning and
building and safety departments to answer questions regarding the proposed buildings. RBF
will prepare for and submit draft and final design plans to the City for plan check for the well
equipping bid set. RBF will coordinate with the City to review plan check comments and make
revisions to the plans, if necessary.
2.5 Drinking Water Source Assessment and Protection (DWSAP) Program
Documents
In 1996, the United States Environmental Protection Agency (USEPA) amended the Safe
Drinking Water Act to require that all states implement a Source Water Assessment Program
(SWAP) for public water systems. The primary purpose of the SWAP program is to promote
source water protection by conducting assessments of those sources. California Department
of Public Health (CDPH) administers this program in California under the DWSAP program.
The DWSAP program provides a proactive “multiple-barrier” approach to protecting drinking
water sources by assessing Possible Contaminating Activities (PCAs) within protection area
boundaries delineated for a particular source. An assessment of the actual drinking water
source and its vulnerability to sources of contamination is also conducted. The ultimate goal of
the DWSAP program is to provide a baseline of information that will be used to prioritize and
direct source water protection measures.
GEOSCIENCE will prepare DWSAP documents in order to assess nearby possible
contaminating activities (PCAs) and to meet State of California and County of Los Angeles
permitting requirements. GEOSCIENCE will prepare preliminary DWSAP documents prior to
construction activities to identify potential sources of contamination that could be of detriment
to the water quality of a well installed at each selected site. The particulars of the DWSAP
documents will be based on information gathered during preparation of the preliminary design
reports in Task 3.0. A final set of documents will be produced following aquifer pump testing
and preparation of pump design recommendations. Preparation of the permit documents
requires identification of all PCAs within two, five and ten year protection zones for the wells.
The protection zones will be delineated using the United States Environmental Protection
Agency’s Wellhead Protection Area (WHPA) model and will be shown in relation to PCAs and
overlain on a USGS topographical map. A figure showing the well protection zones and PCAs
will be attached to the DWSAP documents.
Design, Installation, and Equipping of New Groundwater Wells Page 14 of 29
GEOSCIENCE will submit preliminary and final DWSAP documents for both well sites in
electronic (i.e., PDF) form with three (3) bound hard copies. DWSAP documents will also be
submitted to CDPH to further the Domestic Water Supply Permit Amendment process.
Task No. 3 – Site Assessment & Preliminary Design Report (WELL INSTALLATION)
3.1 Site Assessment Report
Based on readily available data, and field reconnaissance of each site, the GEOSCIENCE
team will prepare a brief site assessment of each of the six (6) potential well sites identified by
the City in the RFP. Each site will be evaluated as to its suitability for installation of a municipal
water supply well, including, but not limited to the following factors:
Aquifer production and storage potential,
Groundwater quality and potential environmental hazards,
Well interference,
Proximity to abandoned or destroyed wells,
Access and area constraints for well drilling, equipping, and well maintenance activities,
Site layout,
Potential impacts to the public,
Proximity to existing water/storm water and other utility infrastructure,
Hydraulic issues & constraints,
Site security,
Proximity to sanitary hazards,
Land use, and
Preliminary cost comparisons.
Based on the initial hydrogeological study and expected well yields RBF will analyze the City’s
water distribution system to verify its adequacy to accept the additional flow that will be
introduced from the new groundwater wells and identify potential impacts to existing facilities
and operations. RBF will analyze up to 6 alternative well sites. RBF will utilize the City’s
existing water system hydraulic model (MWH InfoWater) to simulate inclusion of the new wells
in the distribution system. A technical memorandum will be prepared summarizing the findings
and resultant recommendations of the analysis.
The overall evaluation will be quantified using a decision matrix and each site will be ranked
according to suitability. Results of the site assessments will be presented to the City as a
technical memorandum. GEOSCIENCE will submit an electronic copy of the site assessments
to the City at the 100% DRAFT stage for review and comment. Upon incorporation of
comments, GEOSCIENCE will submit an electronic copy of the 100% FINAL site assessment
in addition to five (5) bound hard copies. The GEOSCIENCE team will attend one meeting with
the City following submittal of the draft site assessment report to discuss the results and reach
consensus on the two optimal well sites.
3.2 Preliminary Well Design Report (PDR)
In preparation of the preliminary PDR, GEOSCIENCE will revisit the selected drilling locations
to identify and assess any logistical issues that may need to be addressed. As necessary,
GEOSCIENCE will supplement background information and geohydrologic data obtained
during the site assessments in order to achieve a thorough understanding of the geohydrology
Design, Installation, and Equipping of New Groundwater Wells Page 15 of 29
of the areas. GEOSCIENCE has much of this data already stored within our in-house
database and GIS systems. This data will include, but is not necessarily limited to:
Construction details of all existing wells in the vicinity of the production well;

lines, electrical lines, sewer lines and manholes, and storm drains.
The PDR will summarize the evaluation of the two selected well sites and will include expected
groundwater quality, groundwater levels, potential well production and storage, potential well
interference, construction logistics and conflicts, environmental issues, and appropriate CDPH
separation distances from existing utilities infrastructure. The report will also include
preliminary designs for the production wells, preliminary site layouts, a basis of design, a
planning-level estimate of contractor costs for well installation, preliminary design drawings,
and a preliminary construction schedule. The preliminary layouts will include the wellhead,
discharge and pump-to-waste piping and valving, meter location, disinfection facilities, building
footprint, emergency generator, electrical equipment, site perimeter fencing, gate, and access
driveway. At a minimum, the PDR will include the following construction details:
Site layouts;
Expected geohydrologic conditions and impact on drilling;
Estimated production and storage capacity;
Recommended well drilling method;
Expected depth and diameter of the well;
Recommended casing materials & dimensions;
Depth of screened intervals;
Filter pack gradation;
Well appurtenances (i.e., sounding and gravel feed tube design);
Site access considerations;
Discharge considerations;
Cuttings disposal;
Sequence of drilling operation; and
Noise abatement measures to be taken during drilling.
GEOSCIENCE will submit an electronic copy of the PDR to the City at the 100% DRAFT stage
for review and comment. Upon incorporation of comments, GEOSCIENCE will submit an
electronic copy of the 100% FINAL PDR in addition to five (5) bound hard copies.
Task No. 4 – Technical Plans, Specifications, & Bidding Assistance (WELL
INSTALLATION)
Design, Installation, and Equipping of New Groundwater Wells Page 16 of 29
4.1 Prepare Technical Plans & Specifications
GEOSCIENCE will prepare detailed technical plans and specifications for the new production
wells. GEOSCIENCE assumes one well construction contract for both wells, and thus one
document containing technical plans and specifications. The technical plans and specifications
will be bundled with the City’s existing General Specifications front-end documents. The front-
end documents will be modified as necessary to suit the specific project. Additionally, detailed
bid schedules will be prepared to be included with the bid packages, with specific line items

GEOSCIENCE will submit electronic copies (i.e., PDF) of a 90% DRAFT and 100% DRAFT
version of the technical plans and specifications to the City for review and comment. It is
assumed that the City will provide two rounds of comments. Comments to the draft versions
will be incorporated and GEOSCIENCE will submit one (1) electronic copy and one (1) bound
Design, Installation, and Equipping of New Groundwater Wells Page 17 of 29
hard copy of the 100% FINAL technical specifications for the wells. The technical
specifications, front-end documents, and construction drawings will be prepared in the City’s
preferred format (i.e., Arial 12 and CSI 3-Part Section Format) using Microsoft Word 2003 and
the latest version of AutoCAD. Construction drawings will be provided to the City as size Arch
D in bond, electronic (i.e., CAD), and Mylar formats, and will be stamped and signed by a
California Registered Civil Engineer.
4.2 Bidding Assistance
GEOSCIENCE will attend a pre-bid meeting with interested contractors and City personnel at
the beginning of the bidding process to discuss key issues in the technical specifications, and
to answer all questions regarding site conditions, preliminary well design, schedule and other
hydrogeologic or contractual matters. During the bidding process GEOSCIENCE will respond
to bidder’s questions and prepare bid addenda as necessary. Once the bidding process is
complete, GEOSCIENCE will review and evaluate all bids received and will provide
recommendations regarding award of the construction contracts. It is assumed that the well
construction for both wells will be bid as one contract.
Task No. 5 – Well Construction Inspection and Management Services
5.1 Construction Management & Coordination
GEOSCIENCE will provide construction management services during the construction process
to ensure that the geohydrologic aspects of the project are carried out in a proper and efficient
manner. Construction management activities will include: review of contractor submittals,
review of contractor invoices to ensure accuracy and completeness, review of and response to
contractor Request for Information (RFIs) and change order requests for legitimacy,
preparation of a final “punch list”, and filing of essential paperwork, correspondence, field
notes, etc. Daily email and/or phone updates will be provided to the City along with submittal
of relevant photographs and daily field logs. All changes to the design will be noted and
recorded in the field for use in preparation of Record (i.e., as-built) Drawings at the completion
of the construction work. Additionally, GEOSCIENCE will periodically monitor the site and
immediate surroundings for compliance with the local noise ordinance during construction.
5.2 Pre-Construction Meeting and Pre-Mobilization Coordination with Contractor
GEOSCIENCE will attend one pre-construction meeting with the selected contractor and City
personnel to review key issues within the contract documents and plans/technical
specifications. In addition, questions will be addressed regarding hydrogeologic and logistical
matters. Items to be discussed at the meeting will include (but not be limited to) required
submittals and inspections, permitting, discharge issues, work schedule, invoicing, and
communication protocols. Additionally, at the time of the pre-construction meeting, the
prospective contractor will have the opportunity to visit the well site to satisfy themselves
regarding conditions that may affect equipment set up. At the time of the meeting, the
contractor will have the opportunity to point out any issues that he/she may have regarding
preparation of the site for the work. GEOSCIENCE will coordinate contractor activities prior to
mobilization. This will include verifying that the contractor has provided all submittals required
by the plans and technical specifications and that equipment delivered to the site meets the
requirements of the plans and specifications. For cost estimating purposes it is assumed that
one pre-construction meeting will be necessary for both wells.
Design, Installation, and Equipping of New Groundwater Wells Page 18 of 29
5.3 Conductor Installation
Full-time on-site field inspection will be provided during drilling of the conductor borehole, and
installation of the conductor casing and sanitary cement seal, to ensure that all materials are
furnished and installed in accordance with the technical specifications and regulatory
requirements. GEOSCIENCE will coordinate with CDPH’s on-site inspector during installation
of the sanitary cement seal.
5.4 Pilot Borehole Drilling and Geophysical Logging
Field inspection will be provided on a part-time basis during pilot borehole drilling. Formation
samples will be collected at 10 ft intervals by the drilling contractor per GEOSCIENCE protocol
(or more frequently depending on the stratigraphy encountered). Samples will be identified as
to material type and production potential by visually logging them in the field using the Unified
Soil Classification System (USCS). Upon completion of the pilot borehole drilling,
GEOSCIENCE personnel will provide full-time onsite inspection of the geophysical borehole
logging (i.e., short- and long-normal resistivity, guard or lateral, self potential, gamma-ray, and
sonic logs). Lithologic chip trays will be prepared and provided to the City at the completion of
pilot borehole drilling.
5.5 Evaluate Geophysical Logs and Select Zones for Isolated Aquifer Zone Testing
Permeable and non-permeable formation material will be identified from the geophysical
borehole logs and from the samples collected during drilling. Based on this information, as well
as information collected during the drilling process, recommendations will be made for the
selection of zones (i.e., depth intervals) for isolated aquifer zone testing. The purpose of
isolated aquifer zone testing is to determine both yield and water quality from the potential
completion interval(s) before determining the final well design. Based on the anticipated depth
of the pilot boreholes, we are estimating that four (4) to five (5) zones will be tested per
borehole. Recommendations for isolated aquifer zone testing will be provided to the City in
letter form for review within 24 hours of the completion of geophysical logging.
5.6 Isolated Aquifer Zone Testing
Once depth intervals for aquifer zones have been identified for selective zone testing,
construction of the zones by the contractor will begin. GEOSCIENCE will provide part-time
inspection during construction and testing of each zone. Specifically, GEOSCIENCE will
provide inspection during zone construction, initial zone airlifting, initial zone pumping, and
during the last six (6) hours of zone pumping prior to water quality sample collection.
GEOSCIENCE always recommends that zone testing be performed at discharge rates
exceeding 200 gallons per minute (gpm) to ensure that representative sampling of the aquifer
is taking place and that the aquifer is being sufficiently stressed to provide the best available
field data. Whenever possible, turbidity measurements taken from the discharge water should
be less than 10 nephelometric turbidity units (NTUs) before collecting water quality samples
from any given zone.
After each zone has been appropriately developed, water samples will be collected by
GEOSCIENCE personnel and delivered to a State of California certified water quality testing
laboratory for general mineral and physical properties analysis (or any other analyses specific
to the well site as may be required). For cost estimating purposes, it is assumed that the City
Design, Installation, and Equipping of New Groundwater Wells Page 19 of 29
will be responsible for the water quality laboratory fees and will contract directly with the
laboratory. Field measurements will also be collected by GEOSCIENCE during each zone test
to determine field parameters such as pH, temperature, electrical conductivity, and turbidity.
Additionally, the discharge rate, and static and pumping water levels, will be measured
frequently during pumping of each zone such that each zone’s productivity can be determined
(including pressure head and specific capacity).
The zone selection and recommended water quality analytical suite will be presented to the
City for approval prior to implementation in the field. It is recommended that the ground water
quality samples collected from the zone testing be analyzed on a 72-hour turn-around time
(i.e., rush) as the results of these analyses are integral for determining the screen interval(s)
for the final well design.
5.7 Additional Isolated Aquifer Zone Testing
GEOSCIENCE will provide part-time inspection for two (2) additional zone tests (one additional
zone per well beyond the four tests per well budgeted) per Task 5.6 above should it be
deemed necessary upon review of the borehole lithology and geophysical logs.
5.8 Mechanical Grading Analysis
Using the visual and geophysical logs collected from the pilot borehole, up to eight (8)
formation samples per well will be selected for mechanical grain size (i.e., sieve) analysis to
assess permeability, sand migration potential, and uniformity coefficients. These analyses will
be used as a basis for preparing the custom filter pack and well screen design for each well.
5.9 Preparation of Final Well Design
Although the anticipated dimensions of the well casing and screen, and the materials used to
manufacture them will be identified during the preliminary design phase, ultimately these
details will be determined based on the results of the borehole lithology, geophysical logs, and
anticipated production rate.
Use of a properly designed and installed filter pack will control sand production from the well
when pumping. Selection of filter pack material will be determined from mechanical grading
analysis, and will be designed based on industry standards regarding pack-to-aquifer ratios.
The size of the screen openings will be designed to allow a minimal but acceptable amount of
filter pack material to move through the screen. This controlled movement of filter pack
material will permit the proper development of the filter pack and near-well zone.
Based on results from the mechanical grading analyses, GEOSCIENCE will design the filter
pack with a pack to aquifer ratio of between 4 and 20, as well as using Terzaghi’s criteria for
the movement of fines through the filter pack, and for the permeability of the aquifer and filter
pack. Based on geophysical logs, mechanical grain size analysis, and isolated aquifer zone
testing, targeted aquifers will be identified. The final well design will include recommended
depth intervals and diameters for the well casing and screen, recommended borehole
diameter(s), and the proper screen opening size to complement the filter pack design.
Recommended depths for the well appurtenances and deep annular seal will also be provided
as necessary. GEOSCIENCE will meet with City personnel to discuss the draft recommended
well design prior to finalization and implementation in the field.
Design, Installation, and Equipping of New Groundwater Wells Page 20 of 29
It is our understanding that the City’s recently completed Master Plan has identified a potential
opportunity to supplement water supplies by diverting, treating, and injecting recycled water
into the aquifer systems through use of aquifer storage and recovery (ASR) wells. To that end,
each of the new wells will be designed and constructed as ASR wells, including installation of a
100 ft surface casing and cement seal, and with large diameter well casing and screen (i.e., 20
inch ID or greater).
5.10 Borehole Reaming
During reaming (enlargement) of the pilot borehole to its final design diameter(s) and depth,
part-time field inspection will be provided to ensure that the work is performed correctly, and
that drilling fluid properties are maintained within the parameters defined by the technical
specifications.
5.11 Installation of Casing, Screen, Filter Pack, and Annular Seal
Full-time (i.e., 24 hour) inspection will be provided during installation of the casing, screen,
appurtenances, filter pack, and annular seal to ensure that all materials are furnished and
placed in accordance with the recommended design and technical specifications. Prior to
installation, GEOSCIENCE personnel will inspect the filter pack material and the well casing
and screen for compliance with the specified well design. As the filter pack and cement seal
are being installed, GEOSCIENCE personnel will track the volume placed against the volume
calculated from the caliper log to ensure that there are no voids or bridges forming within the
annular space. All field changes will be recorded for preparation of the Record Drawings.
5.12 Initial Well Development by Airlifting and Swabbing
Initial well development by airlifting and swabbing is an extremely important component of the
well completion and development process. GEOSCIENCE anticipates that at least 120 hours
of initial airlift development will be necessary for each well. GEOSCIENCE will provide
part-time inspection during the airlift development process and will closely monitor discharge
water turbidity and sand content to track the development progress of the well.
5.13 Final Well Development by Pumping and Surging
GEOSCIENCE will monitor final development by pumping and surging on a part-time basis.
Tests for sand content and specific capacity will be performed frequently to measure the
advancement of the development process and to ensure that the well is fully developed before
beginning the aquifer pumping tests. Well development is considered complete once specific
capacity approaches a maximum and sand content within the discharge approaches a
minimum.
5.14 Aquifer Pumping Tests
Once the well development process is considered complete, aquifer pumping tests will be
performed to determine well and aquifer characteristics. If possible, nearby wells will be
monitored in order to provide interference data and enable more accurate estimation of aquifer
parameters. The following aquifer pumping tests will be performed:
Step Drawdown Pumping Test: time drawdown measurements will be made to
determine specific capacity and well efficiency relationships that are necessary to
calculate the optimal production rate and pump setting. Typically three to four rates are
selected for pumping, beginning with the lowest rate and progressing to the highest.
Design, Installation, and Equipping of New Groundwater Wells Page 21 of 29
Constant Rate Pumping and Recovery Test: time drawdown and recovery
measurements will be made to estimate aquifer parameters. If possible, nearby wells
will also be monitored to obtain interference ground water levels during the test.
Toward the end of the constant rate test, GEOSCIENCE personnel will collect ground water
quality samples and deliver them to a laboratory certified by the State of California for analysis
of water quality constituents required by the State of California’s Title 22 Rule. It is assumed
that the City will be responsible for the water quality laboratory fees and will contract directly
with the laboratory; thus water quality analysis fees are not included in this proposal.
GEOSCIENCE will also provide full-time inspection of flowmeter (spinner) testing typically
conducted during the latter portion of the constant rate testing. The flowmeter testing will be
conducted by a company subcontracted by the drilling Contractor.
5.15 Video and Gyroscopic Alignment Surveys and Final Disinfection
Following removal of the test pumping equipment and bailing of the bottom of the well,
GEOSCIENCE will provide full-time inspection of a final downhole video survey to document
the post-construction condition of the well. GEOSCIENCE will also provide full-time inspection
for a gyroscopic alignment survey of the well, the purpose of which is to measure well
verticality and alignment. Full-time Inspection of the final chlorination of the well will be
provided to ensure that approved disinfection materials, concentrations, and methods are
utilized by the contractor.
5.16 Wellhead Completion and Post-Construction Site Condition
GEOSCIENCE will provide full-time inspection of the final wellhead completion to ensure that
the well casing and appurtenances are finished as described by the technical specifications
and/or well design. The post-construction condition of the well site will also be inspected to
ensure that all equipment, materials, and trash have been removed and that the site has been
restored as closely as possible to its original condition. GEOSCIENCE will prepare a
preliminary and final “punch list” of work remaining to be completed and will attend a final site
walkthrough with the contractor’s representative and City personnel.
5.17 Pump Design Recommendations
Data from the pumping tests will be analyzed and recommended operational parameters will
be provided to the City in letter format, including design pumping rates, short- and long-term
drawdown characteristics, well efficiencies, and recommended pump settings. These
recommendations will be critical to the equipping engineer (RBF), in design of the final well
pump and motor.
Task No. 6 – Comprehensive Well Completion Summary Report
At the conclusion of well construction activities, GEOSCIENCE will prepare detailed final well
completion reports for each well that summarize the details of drilling, construction,
development, and testing. The reports will, at a minimum, include the following:
Chronology of activities;
Lithologic log based on the drill cuttings;
Mechanical grading analyses;
Geophysical, video survey, and gyroscopic alignment survey logs;
Design, Installation, and Equipping of New Groundwater Wells Page 22 of 29
An as-built diagram of the new well;
Analyses and results of aquifer pumping tests;
Zone test and Title 22 water quality data;
Aquifer pumping test results;
Recommended pump setting, production and storage rates, short- and long-term
drawdown;
California DWR well completion report;
Record (i.e., as-built) Drawings; and
Other pertinent data and analytical results.
GEOSCIENCE will submit an electronic copy and three (3) bound hard copies of each of the
100% FINAL well completion summary reports (two reports). Each well will have its own
report.
Task No. 7 – Preliminary Design Report (Well Equipping)
7.1 Preliminary Design Report
RBF will prepare a PDR, documenting the well equipping design for each well. The reports will
provide a description of the well equipping systems, including well pump/column pipe/motor
design criteria, waste discharge system, discharge piping and appurtenances, disinfection
system, power requirements, backup power system, and any recommended modifications to
existing facilities, if required. The PDR will analyze alternative well enclosures/access features
for the City for both aesthetic (appearance and noise) and maintenance (well rehab) purposes
and identify benefits and disadvantages of each alternative. The report will also analyze the
cost/benefits of equipping the wells for both aquifer storage and recovery capabilities (i.e.
ASR). RBF will provide a concept ASR well layout sufficient for providing an adequate
estimate of capital cost for the ASR option. Included in the cost analysis will be the potential for
energy recovery using conventional or in-pipe turbines.
The report will include a preliminary schedule for completing the final design and construction
of well equipping, and a preliminary engineer’s estimate of probable construction cost.
The report will reiterate the mitigation factors identified in the CEQA Mitigated Negative
Declaration document for this project and describe how these mitigation factors have been
taken into consideration in the proposed design.
Three (3) bound hard copies and one electronic (i.e., PDF) copy of the draft report will be
provided to the City for review and comment. City comments will be incorporated into the
final report. Four (4) bound hard copies and one electronic copy of the final report will be

7.2 Analysis of Alternative Power Supply and Backup Power
RBF will prepare a present worth analysis that evaluates the capital and annual operating costs
of electric motors versus natural gas-driven engines as the primary power source for the wells.
The analysis will take into consideration TOU and GN rates for electricity and natural gas,
respectively. The analysis will also include a cost comparison for providing a portable diesel
generator versus installing a permanent diesel or natural gas generator at each well site for
backup power. The analysis will identify permitting requirements from SCAQMD, permitting
costs, and potential for rebates from SCE and SCG.

Task No. 8 – Plans and Specifications (Well Equipping)
8.1 Plans and Technical Specifications
RBF will prepare a set of Contract Documents; Plans, Specification, and Engineer’s Estimate
of Probable Construction Cost (PS&E) required for obtaining Contractor’s bids for the Well
Equipping project. The City will provide its standard “front end” documents to RBF for
incorporation in the project’s Contract Documents. For cost estimating purposes, the
GEOSCIENCE / RBF team assumes one well equipping contract for both wells. There is an
optional item included in the cost proposal for the additional costs required should the City
decide to bid the well equipping as two separate packages.
The level of effort for this task is based upon the following assumptions:
One bid set will be prepared for the two wells.
Each well will be housed within a small block masonry building (approximately 20’ x 30’)
with a standing seam metal roof.
The buildings will house the wellhead and electrical equipment, and will provide space
for future disinfection equipment, if required.
The building layouts for each site may vary somewhat from one another but are
anticipated to be the same material, similarly sized, and detailed.
Space will be provided in the buildings for an emergency disinfection system assuming
the system will be bulk sodium hypochlorite.
The well pump will be a vertical turbine deep well pump with electric motor.
Backup generator will be a diesel or natural gas generator as determined in 7.2, housed
outside in a sound-attenuated enclosure
Topographic survey files will be provided to RBF by the City in AutoCAD format,
sufficient for use as base files for the design.
Traffic control will be per MUTCD and WATCH Manuals. Preparation of traffic control
plans is excluded.
Landscaping and irrigation at each site will be limited and therefore one
landscape/irrigation plan sheet is provided for each well site.
Design of ASR wells is not included in the final design effort.
Plans: The Contract Documents will cover the necessary aspects of the Well Equipping
project, including but not limited to the following:
1. One plan set for Well Equipping (Assumes 52 drawings as detailed below)
2. General conditions such as permitting, noise control, site security, and conduct,
OSHA compliance, dust control, hours of operation, etc., will be provided upon
consultation with the City.
3. Specifications to include: pump and motor, standby generator, piping and
related items, water meter, electrical conduit and space provisions for future
disinfection system, electrical, control and motor control center, Local Well
RTU/PLC, block masonry building with standing seam metal roof, on-site
drainage and discharge requirements, site work, site perimeter/walls and modest
landscaping/irrigation, quality control and testing, parking/traffic control, and
security/lighting improvements. Specifications will be prepared in CSI format on
Microsoft Word platform.
