Contractor will obtain samples of the drill cuttings at 5-foot intervals which will be used to
characterize the drilled geologic section. Borehole geophysical logs will be run by the
Owner in the mud-filled, 8" bore and compared to the drill cuttings.
C. Drilling. Below the eight-inch surface casing the well shall be drilled at eight (8) inch
diameter to accommodate the six (6) diameter well casing, filter sand, bentonite seals
and four (4) inch diameter well screen assembly. Drilling will be in sediments such as
clay, silt, sand and/or gravel. Artesian flowing (above ground) conditions are possible at
this site within the deeper section. Static water level from approximately 800 feet below
ground is predicted to be within a few feet of ground level. The Contractor shall provide
well drilling rig and well tools as required, and atl other equipment, materials and
supplies required for drilling and completion of the well. All such equipment shall be in
goad condition and properly maintained.
3.03 Well Seals.
A. The surface seal, intermediate seals, and abandonment plugging of the well shall
consist of abentonite-based, °high-solids° (>30% by weight) and NSF approved grout
especially manufactured for use as a grout in water supply wells such as CETCO
Volclay Granular Grout or approved equal. The grout solids shall be maed with clean
water at a ratio that results in a low-permeabilitj+ (< 1 X 10 '~ cm/sec.) seal and placed
with a positive displacement pump. In general, grout seals will be placed by pumping
from °the-bottom-up" whereby the grout tremie pipe is lowered to the base of the
proposed seal and pumped until grout return (at the desired consistency) is achieved at
the surface. It is recognized that, in deeper and/or extensive seal placements, that the
tremie pipe may have to be raised at intervals, as the seal is placid, to compensate for
setting of the grout and to overcome down hole artesian pressures. The tremie pipe will
be of steel pipe or minimum schedule-80 PVC plastic construction and have a minimum
inside diameter of 1 % -inches. The bentonite powder shall be dry and packaged in
waterproof bags. Bentonite grout shall be mixed with exact quantities of water and
solids according to manufacturer's recommendations to achieve the desired density.
The Contractor will be required to demonstrate the fluid capacity of ungraduated tanks or
irregularly-shaped grout mixing containers and supply an on-site mud balance for
measuring grout density. Full-depth surface seals shall be placed in as continuous and
uninterrupted manner as possible. The Contractor shall notifjr IDWR at least 24 hours
prlor to grout seal placement and the Hydrogeologist shall be on site for the entire
mixing/seal placement process.
3.04 Well Screens.
A. The Contractor shall furnish and install the appropriate screen with the length and slot
size as directed by the Hydrogeologist. The type, length and depth of screen will be
determined from geophysical logging of the mud-filled pilot bore. The screen slot size
will be determined from grain size analyses of the well cuttings from the exploratory test-
welt and screens may not be ordered in advance. One of firoo types of screen will likely
be used depending on the drilled geologic section encountered. Either 2-inch PVC
slotted pipe will be connected to two-inch flush joint PVC pipe(s) or 4-inch diameter
stainless steel, continuous V wire wound well screen shall be placed though a six inch

diameter steel casing. Either application will utilize 10-foot lengths manufactured by U.S.
Filter "Johnson" screens or approved equal. If stainless steel screen is used, the screen
sections shall be equipped with stainless steel welding rings at both ends. Weld rings
shall be of 6-inch length to allow for welding of centralizer staves on both ends and
safely away from screen wires. If PVC screens are used, spring steel, bolt-on
centralizers will be used to center the well screens. PVC screens shall be of the same
construction and plastic specification as the Schedule 80 PVC casing
3.05 Sand Filter.
A. After the PVC screen assembly has been installed in the well, the Contractor shall
introduce a graded sand filter, approved by the Hydrogeologist, into the annular space
between the drilled geological section and the well screens by pouring through a tremie
pipe extending to the top of the screens. The filter shall be added in a continuous pour
as approved by the Hydrogeologist until it is stabilized and the complete annular space
is filled to the appropriate level. In the case that 4-inch stainless screens are used, a
"natural filter pack" shall be developed without the addition of a graded filter.
3.06 Packer/Reducer Assembly.
A. In the scenario where 6-inch casing is coupled w~h flinch diameter stainless screens, a
packer/reducer seal assembly shall be welded to the top of the screen assembly as a
seal between the surtace casing and screened liner. The Hydrogeologist shall be on-site
during installation of the screen assembly and shall inspect the packer prior to
installation in the well. The Contractor shall take care to ensure the rubber seals are not
compromised during installation and/or fabrication of the packer/r~ucer. Special care
must be taken during welding of the packer to the reducer assembly to prevent heat
damage to the neoprene adhesive and/or the rubber seal. Immersion of the neoprene
section, in cold water, during welding may be necessary to avoid damage to the rubber
seal.
3.07 UUell Development
A. The Contractor shall bail any infill and drilling fluids from the bottom of the well(s) and
purge the well by air-lift pumping until clear. If more than one tube is installed, at least
two piezometer tubes shall be air-lifted simultaneously. Costs associated with air-lift
purging and diversion of the discharged water are the responsibility of the Contractor
and shall be considered incidental to the project.
B. Upon installation of the screens and filter sand, and after air-lift purging of the well, the
Contractor shall settle and clear the sand filter by surging and swabbing with a surge
block, wire-brush, and/or bailer. Development shall continue until no appreciable
amount of material is brought into the well after thirty (30) minutes of vigorous surging
and the natural filter pack is completely developed. Upon completion of well-
development, alt materials shall be thoroughly cleaned from inside the casing and
screens to the total depth.

SECTION 02587
DIRECT MUD-ROTARY METHOD
C. It shall be the Contractor's responsibility to notify the Hydrogeologist prior to the
development process so they may be present during the first pumping of the well and to
provide daily reports of progress during development. The use of a dispersant,
surfactant, detergent or any other well-development agent is likely and shall be approved
by the Hydrogeologist prior to use.
3.08 Records and Samples
A. A detailed log or record shall be kept current (as the well is drilled) by the Contractor's
driller on a form suitable to the Hydrogeologist which shall indicate, for each shift
worked, the general character, thickness, color, and type of material encountered, any
lass of fluid or caving of the drilled formation, and the nature and extent of all other work
performed including the time spent on each item of work. The log shall be maintained .at
all times at the job site and shall be available at anytime for inspection by the Owner or
the Hydrogeologist. Upon Completion of the work, a complete copy of the driller's field
log shall be furnished to the Hydrogeologist. The Contractor, after conferring with the
Hydrogeologist, and after the hydrogeologist has had an opportunity to review (and edit
if necessary) the Well Driller's Report, shall also file with the State Department of Water
Resources the necessary log and record on forms obtainable from that Department.
The Owner and Hydrogeologist shall also receive clear readable copies of the State of
. ldaho Well Driller's Report.
B. Samples of all materials penetrated during drilling shall be taken by the Contractor at
every formation change and every five (5) feet below land surface. Samples shall be
taken from the drill discharge and caught in a container capable of retaining fine sands
and silts within the drill stream. This may require catching a bucket of the drill stream
and allowing it to settle to collect representative cuttings. Every effort shall be made by
the Contractor to ensure that samples are representative of the drilled geologic section.
Cumulative sampling (taking portions of a given sample continuously over the 5-foot
sample interval) is required. Samples shall be saved and maintained on the job site by
the Contractor. The samples shall be of at least one pint size, shall be kept in sealed,
quart-size "Zip-Lock" type, 4 mil clear plastic freezer bags to be provided by the
Contractor, and shall be clearly labeled with a waterproof marker to show the depth
interval from which the sample was collected, the date, and well name. All sample bags
shall be sealed and water tight to prevent leakage during transport.
C. Because the drill-cuttings will be transported away from the site for analysis and
disposal, the Contractor shall keep an up-to-date record of the drilled section. The
Contractor, alone, is responsible for supplying the field record of the drilled section and
shall not rely on the interpretations or notes of others.
3.09 Borehole Geophysical Logs.
A. Upon reaching total drilled depth, and immediately following removal of the drill steel, the
Owner shall arrange for a suite of borehole geophysical logs to be run in the uncased
borehole below the surface casing. The Contractor shall be responsible for removing
the drill steel and maintaining the well in an open condition to the full drilled depth to
accommodate the geophysical logging. The Contractor will be required to lower a

DIRECT MUD-ROTARY METHOD
section of drill steel to the bottom of the bore, using their sand-line cable, prior to logging
to ensure that the bore is open to depth with no obstructions and/or mud-rings. The
Owner is responsible for scheduling the geophysical logging immediately after the drill
steel is removed from the hole. No additional payment will be made to the Contractor for
the time required for the geophysical logging or if the drill steel has to be run to dep#h to
clear the well to allow full depth geophysical logs. A plan for well completion and
construction materials list will be supplied to the Contractor within 48 hours of the
completion of the geophysical logging. The Contractor shall maintain the bore hole full
of drilling mud at all times until the well is completed.
3.10 Dlslnfection
A. The Contractor shall disinfect the well in accordance with applicable sections of AWWA
A100 and C654 after development is complete and all tools have been removed from the
well. This item is considered incidental to the project and no additional payment will be
made for its completion. The chloride (CIZ) solution shall be poured through the water
column from the surtace. Liquid bleach (12% sodium hypochlorite solution) without
additives, enrymes or other laundry-related enhancements is the preferred disinfection
solution. The well bore volume shall be brought to a concentration of 250 mg CIZ/L. The
Hydrogeologist shall be present on-site during disinfection of the well.
3.11 Hydraulic Pump Testing and Water-Quality Sampling.
A. General. Upon completion of the development of the well, the Contractor, at the
direction of the Hydrogeologist, shall test the well(s) to determine the water-quality of the
aquifer. Two possibilities exist: 1) The first scenario is if the well is completed with
several 2-inch piezometer tubes and 2) the second instance will be if the well is
completed as a six-inch diameter well (with 4-inch diameter screens} to a single aquifer
unit. Pumped water will be discharged on site to the small irrigation lateral adjacent to
the si#e. Contractor shall supply electrical power generator, air-compressor, piping, and
all equipment necessary to conduct the pump-testing and wafer-quality sampling. Other
than water from the municipal system, utilities are not available at the site.
B. Two-inch oiezometer--nest scenario. After thetwo-inch tubes have been swabbed,
bailed, and cleared by air-lift pumping, a sampling pump capable of supplying 10 gpm
will be installed in each of the tubes and operated to obtain water-quality samples to be
taken by the Hydrogeologist. Pumping of each zone will continue until the water has
cleared and until field-measured water chemistry parameters are stable prior to
sampling. Sampling pump and hoses shall be clean, new, and disinfected prior to use.
C. Six-inch casino. single-comoletion interval scenario. After the well has been swabbed,
bailed, and cleared by air-I'ift pumping, a submersible pump will be installed in the well to
a depth of 200 feet. The pump shall be capable of delivering a continuous supply of 150
gpm from a depth of 200 feet for eight hours. Testing equipment, including electrical
power generator, shall be able to maintain 150 gpm without overheating for the duration
of the test (8-hours). Testing shall be with a standard turbine pump.

Electrical power is not available at the site so that the Contractor shall be responsible to
supply an on-site power generator capable of supplying the necessary horsepower to
meet the stipulated conditions. The Contractor shall furnish and install all necessary
equipment for the testing and for measuring accurately the discharge from the well and
the water level in the well during the testing operation. A properly rigged circular orifice
weir is preferred for discharge measurement although a recently calibrated high-quality
flow-meter, or timed filling of a 55-gallon drum are also acceptable means of measuring
flow. A control valve for regulating flow will be installed at the well head. A minimum
0.5-inch diameter, continuous (un-spliced) sounding tube shall be installed, with the
pump column, to five feet above the pump intake. Sounding tube shall be taped or
otherwise affixed to the pump-column so that it is straight, but not so tightly bound that it
becomes kinked or restricted so as to not allow a 3/8-inch electric sounding line to pass
freely to the pump intake. Sounding tube shall be attached, affixed, or otherwise
extended past, away from, or below shaft lubrication (if applicable) so as to prevent oil
lubrication from entering and/or fouling the sounding tube and to avoid pressure
fluctuations associated with the pump intake.
The Contractor shall be responsible far making arrangements with the Hydrogeologist
for the accurate measurement of discharge and satisfactory disposal of water during the
test period. Discharge shall be conducted to a nearby irrigation lateral and the
Contractor shall be responsible for obtaining permission from the appropriate parses for
the discharge. Discharge shall be adequately attenuated, diffused, sand-bagged, or
otherwise shielded so as to prevent hydraulic damage to canal banks, streets,
sidewalks, and/or property. The Contractor shall be responsible for the repair of damage
caused by the discharge water. All discharge-piping joints shall be taped against
leakage and supported sufficiently to prevent movement during the test-period.
D. Test-duration. Test pumping is estimated to be conducted over atwo-day period
whereby swell-development test period will last an estimated 8 hours. After overnight
recovery from the development testing, a constant discharge hydraulic test will be
carried out for at least 8 uninterrupted hours. Based upon draw down characteristics of
the well, the hydraulic test period may be extended or shortened at the discretion of the
Hydrogeologist. The Contractor shall be responsible for providing a means for safe
refueling during operations, to prevent even brief shutdowns during the test and to
maintain the discharge constant at specified rates.
E. Water-auality sampling. Near the end of the constant pumping-test, water-quality
samples will be obtained by the Hydrogeologist from asample-port, provided by the
Contractor, near the discharge head of the test-pump. After completion of the testing
and removal of the test pump, the Contractor shall arrange to bail, pump, skim, or
othenrvise remove and containerize any oil which has accumulated on the top of the
water column during the test periods
Upon removal of the test-pump, the Contractor shall securely cap the well by welding a
1/flinch thick plate to the top of the casing. The Owner shall arrange for a downhole
television camera survey and final disinfection of the well. Payment for furnishing,
installing and removing the testing equipment shall be at the applicable lump sum price
