CITY OF UKIAH
GROUNDWATER WELL SITING STUDY
SCOPE OF SERVICES
Brown and Caldwell has developed the following scope of services to address the project needs.
Phase 1, Task 1— Perform Feasibility/Well Siting Study
The following tasks describe BC's efforts during the feasibility/well siting assessment phase of the
project. These tasks are considered to be the most vital components of the project since past and
e�sting wells in and in the vicinity of the City have varied dramatically with respect to water quality
and production capacity. The fundamental viability of constructing, developing and testing highly
productive and reliable production wells with acceptable water quality will hinge upon a well-
researched all-encompassing hydrogeological evaluation of the Cit�s underlying aquifers. 'The goal
of this task is to deterinuie the best potential locations within the Cityto develop reliable, high-
capacity wells. The test well siting suiTU�riary report with recommendations is anticipated to be
delivered to the City within appro�mately f our months.
Task 1.1.1—Conduct Record Search
BC will acquire and review available data from the City: DHS documents and Drinking Water
AdequacyAssessment reports,State of California,Department of Water Resources (DWR); U.S.
Geological Survey�, State of California,Department of Oil, Gas and Geothermal Resources
(DOGG);Mendocino CountyEnvironmental Health; geological publications; and other relevant
sources pertaining to performance, production, construction features, and water qualityof past and
e�sting wells located within and in the vicinity of the City limits. DOGG geophysical logs will be
reviewed and utilized to help identify and characterize deeper formations that exist below current
well depths. DOGG logs, when available, provide invaluable geophysical data from the ground
surface to the lower reaches of non-brackish potable water. BC will also contact local drillers,
including Weeks Diilling of Ukiah, for information on local groundwater conditions.
Task 1.1.2—Conduct Hydrogeological Investigation
BC will review available hydrogeological information on the regional aquifers underlying the City.
BC will use the available hydrogeologic data to estimate relative extent,thickness and yields of the
aquifers below the City and prioritize areas for potential new water supply wells. Since water quality
is a key consideration,BC will review e�sting water quality data from the City and other available
sources. If additional e�sting wells are identified that are accessible and can provide useful
information to the hydrogeological study,we will coordinate the collection and analysis of the
samples by a state certified laboratory of the Cit�s choice.
Task 1.1.3—Deterniine Physical Parameter Characteristics
BC will compile data regarding available utility power,physical properties, land ownership and use
issues, and other potential site characteristics for the sites that the City owns, the former site of the
old Ukiah Wastewater Treatment Plant on Perkins Street, and the Granite Construction gravel mine
on the east side of the Russian River across from the Cit�s Water Treatment Plant. This task will be
an important element of the project since a site might appear to be promising on a hydrogeological
basis, but be difficult to construct a well on because of a physical barrier(s) such as overhead
electrical wires,distance to the City distribution system, pro�mity to residential dwellings, and
required regulatory agency setbacks. These issues are best addressed prior to test well diilling to
Page 1 of 5
ensure a successful production well project.Moreover, each potential site should and will be
evaluated with respect to the key requirements of the DHS's Drinking Water Source Assessment
Program (DWSAP), which is a mandatory submission when applying for a new municipal well's
operating permit.
Task 1.1.4—Obtain Environmental Check
BC will have Environmental Data Resources (EDR) radius checks performed at strategic locations
within the City to identify reported hazardous material leaks and spills that could jeopardize a
production well's reliability and the ability to pexrnit it. EDR radius checks search environmental
databases such as the National Priority(Superfund) List,the United States Department of
Transportation Hazardous Materials Information Reporting System, the California Department of
Toxic Substance Control to locate past spill/leak history and current threats in specific areas. This
environmental check data will be utilized to vet and rank potential test well sites and the results of
this analysis will be included in Task 1.1.5.
Task 1.1.5—Prepare Test Well Siting Summary Report
Using the information compiled in the previous tasks,BC will provide a ranking of the Ciry-owned
and the two additional properties and recommend via a sununary report the location of at least two
areas within the City where test wells and, ultimately, production wells can potentially be
constructed. BC will present the recommendations of the report to the City staff on a face-to-face
basis and will address all comments. Additionally, BC will work closely with the State of California
DHS and will seek their approval for the potential drilling locations.
Del�rables: Recommendation Surrunary Report and associated attachments, charts, graphs and
maps.
Phase 1, Task 2— Drilling and Construction of Test Wells
The following task describes BC's efforts during the drilling and sampling of two test holes and the
construction, development and testing of test wells. The goal of this task is to obtain the requisite
information that is necessaryto ultimatelydevelop production wells that will yield an acceptable and
reliable quantity of groundwater with suitable water quality. The vital data and physical specimens
that will be acquired during these tasks will include, but not be limited to: formation samples from
the test borings, geophysical logs of test bores, depth- and aquifer-specific water samples,
production yield estimates, water quality results, and water bearing forn�ation sieve analyses. This
task is anticipated to be completed within approximately five months after the City has approved the
selected sites. This scope does not include the costs of the drilling contractor or its subcontractors
(such as water quality laboratories or geophysical logging),which will be contracted directly by the
City.
Test Well Drilling Approach
The geology beneath the City will consist primarily of layered deposits of clay, silt, sand, gravel, and
rock. The water-bearing sands and gravel (aquifers) will likelybe located between impermeable
layers of clay(aquitards) and vary in thickness and potential to yield water. Each water-bearing zone
will possess distinct water quality chemistry and constituents such as arsenic, iron, nitrate,
manganese,etc., can range from non-detectable to DHS MCL-exceeding values. To develop a well
with acceptable water quality,it will be essential to reliably determine the water quality chemistry of
the individual water-bearing formations prior to designing a new production well's blank casing and
screen design locations. Aquifers that have undesirable water quality can be excluded from a new
well by utilizing well design features such as intermediate annular seals, blank casing, and
discretionary well screen placement.
Page 2 of 5
The test hole drilling, soil sampling, geophysical logging,test hole reaming,well construction,well
development, test pumping, and water quality sampling will be conducted by an independent
licensed drilling contractor contracted directly by the City using a truck-mounted drilling rig
equipped with mud rotary or air rotary drilling equipment. The selected drilling method will be
deternuned by site-specific conditions as identified in the "Well Siting Sun-unary Report." During
drilling activities, formation samples will be continuouslycollected and preserved bythe driller for
classification according to the Unified Soil Classification System by a BC California Professional
Geologist (PG). Sieve analysis of these samples bythe driller will provide the design basis for the
selection of the test and production wells' gravel pack material and screen aperture size. Sand-free
groundwater production is very important to the longevity of a well and pump, and the proper
selection of a well's gravel pack/screen opening size is a crucial factor in obtaining the sand-free
condition.
A test well's construction chronology will follow the pattem described below:
Drill an exploratory borehole with mud or air rotary techniques to a prescribed depth and
collect continuous formation samples
Preservation and classification of formation samples according to the Unified Soil
Classification System by a PG
Perform geophysical logging
Ream the test bore to an appropriate diameter, +/- 12-inch diameter, and install 4-inch- or
6-inch-diameter casing and well screen
Install gravel pack and intermediate seal materials
Perform preliminary well development to cause annular material settlement
Place the cement surface annular seal per regulatory agency requirements
Complete well development and perform test pumping activities
Collect depth-specific water samples for laboratory analysis
The filter gravel pack material will be placed, bythe drilling contractor, in the annular space between
the casing and the borehole up to a minimum distance of 20 feet above the top of the uppermost
well screen interval. The test well will then be developed utilizing bailing and surging methods, a
two- to three-foot thick seal of bentonite pellets will be placed on top of the gravel, and a sand-
cement grout that e�ends to the ground surface will be installed with a grout pump and tremie pipe
to assure a continuous, impervious, surface seal. The top of the test well will be completed with a
cement pedestal and a lockable well cap in compliance with State and County well
standards/ordinances.
The State of Calif ornia Regional Water Quality Control Board requires a low threat, short duration,
discharge permit before groundwater is pumped and discharged to any disposal point. Groundwater
from the test well(s) will be collected and analyzed for chemical constituents by a State certified
laboratory subcontracted by the driller or by the Cit�s laboratory and the results will be utilized to
justify and obtain the required discharge permit(s). Depth-specific water samples obtained for
aquifer characterization will be analyzed for the full array of components required bythe California
Code of Regulations Title 22.

Task 1.2.1—Develop Test Well Work Plan
BC will prepare a Quotation Form and Work Plan to be used to obtain competitive proposals for
the two test wells. The Work Plan will address test hole drilling, logging protocol,test hole reaming,
well casing, well screen type, acceptable development techniques, and test pump requirements for
the drilling contractor. The final test well design will be based upon the inforn�ation gathered from
the test hole. The Work Plan Technical Specifications will be generated to establish work
descriptions, acceptable materials, project execution procedures, record keeping/submittal
requirements, and contract payment measurements. The Work Plan Technical Specifications will
also address the critical test well constnzction issues listed below:
Drilling methods, fluids, and control
Borehole sizing
• Formation sampling procedures
- Downhole geophysical logs
Casing size and material requirements
Gravel pack material
Surface and intermediate seal placement
Development procedures
Test pumping protocol
Depth-specific water sampling acquisition and analysis specifications
Other appropriate project/contractor requirements
In addition to the Technical Specifications,Work Plan Special Conditions will be prepared that
address site-specific requirements such as:
Construction water availability
Site securiry
Noise suppression
Fluids/solids waste disposal
Site restoration
Acceptable hours of work
Insurance requirements
Other site-appropriate contractor requirements/project constraints.
After City review and acceptance of the Bid Schedule,Work Plan Technical Specifications and
Special Conditioris,the documents will be provided to potential project bidders. BC will identify
qualified drilling contractors and will receive and evaluate project proposals.
Page 4 of 5
Task 1.2.2—Provide Sidding Services and Construction Observation
During the Cit�s well quotation process,BC will respond to questions from the drilling contractors
for clarification of the test well Work Plan.
Services during construction are critical to the successful completion of a test well that meets all
project goals. During construction, BC will provide the following well construction related services:
Develop agendas and attend pre-construction and contractor status meetings.
Review shop drawings, submittals, and other data such as geophysical logs, gravel pack
selection, etc.,which the contractor is required to submit in conformance with the design
concept and that specified in the contract documents.
Provide final test well design details to the well drilling contractor based upon formation
samples and their sieve analyses, geophysical logs, and other hydrogeological data.
Make visits to the project location at intervals appropriate to the various stages of
construction to observe the progress of the contractor's executed work and to determine, in
general,if such work is proceeding in accordance with the Work Plan. Construction
observation is critical to the successful completion of a test well. Therefore, a significant
amount of construction observation is recommended and proposed.
BC will prepare record drawings of the completed test well based on information supplied
bythe contractor and a letter report documenting the test pumping results,well equipping
recommendations,water quality data, and other important project information.
Task 1.2.3—Prepare Record/Recommendation Report
After construction of the test wells,BC will provide a Record/Recommendation Report (Report)
that provides construction records detailing the test wells' construction features, formation logs,
geophysical logs, water quality results,test pumping results, and other relevant data. Moreover,the
Report will provide recommendations regarding whether or not production wells can be successfully
completed at the test well locations, and if so,the Report will provide production well design and
construction criteria. If it is judged that production wells cannot be successfully completed at the
test well locations,BC will recommend whether the sites are suitable for geothermal power
generation. BC will present the Report to the Ciry Council at a regularly scheduled City Council
meeting and will provide the appropriate presentation material such as map handouts, design
drawings, charts/tables and Power Point graphics, if appropriate. Production well construction
methods, features and logistics that will be included in the Report recommendations are:
Well drilling technique (direct mud rotary, air rotary, or reverse circulation rotary)
Most favorable drilling mud program
Well screen depth intervals and intermediate annular seal locations
Surface annular seal depth
E�ernal TV access/sounding pipe diameter and entry depth
Borehole, blank casing and well screen diameter
Most effective development methods
Fluid discharge requirements
Other well design features
Production well cost estimates
Deli�rdbles.• Work Plan Technical Specifications and Special Conditions, Quotation Form,
Record/Recommendation Report and associated attachments, charts, graphs and maps.
