INTRODUCTION
This document will serve as the After the Fact Drilling Specifications Governing the Drilling
of the Terakee Farms Water System Well 1. In 2023, a well was drilled and constructed in
the Delta Aquifer in Weber County south of Plain City and west of Mariott-Slaterville,
locally known as West Weber. The well was drilled using dual rotary casing advance dual air
rotary with 8-inch casing to 600’. A six-inch well was then constructed to 490’ and the 8-
inch casing was removed. Thirty feet of 6” stainless steel wire-wrapped screen was installed
from 430-460’ and the native materials were allowed to fill the annular space around the
well. A bentonite seal was installed from the surface to a depth of 60’. Except for the sanitary
seal and pump test requirements, this well was constructed to Source Development Code
309-515 and Utah Water Rights Code R655-4 for well construction standards. This document
will summarize the methods of construction as after-the-fact and also outline the drilling
specifications for the installation of the sanitary seal and forthcoming pump test, including
details of the methods that will be used to remove the existing seal and native materials so
that a sanitary seal meeting R309-515-6(6)(i) may be installed and certified.
Because a professional geologist or engineer did not assist with the design of, and was not
present for the drilling of the well, this document summarizes the drilling methods and
construction from the well driller’s report (Figure 1) and conversations with the well owner.
This document will be used as a guideline for the Utah Division of Drinking Water (DDW)
for drilling, construction, development, and pump testing of the well. The final parameters
may change regarding the sanitary seal.
1.1 Funding of Project
This is not a funded project; therefore, there are no additional specification requirements in
addition to Utah Division of Drinking Water (DDW) and Utah Division of Water Rights
(DWRi) rules and regulations regarding the drilling, construction, development, and pump
testing of new sources for a Public Water System.
1.2 Project Start & Location
A change application has been completed and the location of the well is shown on Figure 2
located approximately N1100’ E530’ S4 17 6N 2W SL. The well was completed in April
2023 and the system proposes redrilling and setting a sanitary seal as soon as a driller can be
contracted.
DRILLING METHOD AND APPROACH
2.1 Drilling Method
The drilling method used was air dual rotary.
2.2 Drilling Approach
The well was drilled to 600’ by High Plains Drilling using a Foremost 24 Dual Rotary Drill.
Dual rotary is a casing advance method of drilling where the casing is installed
simultaneously with the drilling to hold back the formation. The casing can then be
perforated in place or pulled after a smaller diameter well is constructed. The driller
constructed a 6” well to 490’ and pulled the 8” casing, allowing the formation materials to
U29130-WS001-Drilling Specifications-2024
-2-
February 14, 2024 Terakee Farms Water System Well 1
fill the 2” annular space around the constructed well. A 60 foot seal of bentonite was
installed while pulling the temporary casing.
Source Development Code R309-515-6(6)(i) requires a certified 105-foot sanitary seal be
installed. Therefore, a new driller will be contracted to over-reem the existing 6” well,
creating a minimum 4” annular void space to install a compliant sanitary seal. This will
involve a specialized annular over-reeming bit which will leave the 6” well casing in place
while boring an annulus to a minimum of 10 ¾” outside diameter. If the driller choses, he
may install a temporary conductor casing to hold back the formation during drilling and pull
the casing as the sanitary seal is poured. See section 3.7 for sanitary seal details.
DRILLING, CONSTRUCTION, DEVELOPMENT AND PUMP TESTING
The as built well construction diagram, with modification in violet, is shown in Figure 3. As
noted in the text above, the diameter and depth of the sanitary seal will be dependent on the
drillers tooling, geology, and hydrology encountered. Preferred design is that seal will be a
10 ¾” diameter to accommodate the minimum 4” annular space required for the sanitary seal
but the driller may opt to drill it larger if required by tooling or formation characteristics. The
sanitary surface seal will be witnessed by a representative of DDW or another approved
person.
In addition to the sanitary seal drilling, the selected driller will verify the well has been
developed sufficiently and perform a minimum 24-hour to week-long constant pump-rate
aquifer test.
Substances introduced into the well during construction or development shall be certified to
comply with ANSI/NSF Standard 60, 61 or equivalent. This applies to all drilling fluids,
circulation materials, lubricants, weighting agents and any other fluids used during drilling.
This will also apply to well grouting and sealing materials that may contact drinking water.
3.1 Drilling Fluids
As stated in R309-515-6(6)(j) and R655-4-11-6.5, any water entering a well during
construction or preparation of any other materials entering the well shall not be contaminated
and should be obtained from a public water supply system. If water cannot be sourced from a
public water supply it will be dosed to give a minimum 100 mg/L free chlorine residual in
accordance with Table 7 in R655-4-11-6.5.
All fluids entering the borehole will be in accordance with UAC R655-4-11.6(6)(a),
ANSI/NSF Standards 60 and 61 and UAC 655-4-11.6.1. If drilling fluids are used, NSF
approved bentonite mud and polymers will be used to lift cuttings from the borehole. No lost
circulation material (LCM) will be allowed to be used below the water table.
3.2 Disposal of Cuttings
Cuttings and waste from the well will be discharged in a manner consistent with rules and
regulations of the Utah Division of Water Quality. These cuttings are unconsolidated,
unmineralized valley fill sediments which will were dispersed on-site during regrading.

3.3 Casing
This well will is a single casing construction. All casing used was of adequate size, strength,
and wall thickness for the well construction design determined by the driller. The casing of
the final well was 0.250 6” O.D. steel. All permanent casing installed into the well will was
A 53 B steel, meeting all DWRi and DDW rules and regulations regarding casing, including
but not limited to; UAC R309-515-6(6)(b), Permanent Steel Casing Pipe and R655-4-11.2.3,
Well Casing - General - Steel Casing. All steel casing was in new condition. Casing was
carbon steel pipe, conforming to ASTM A 53, Type E, Grade B. Casing joints were welded
in accordance with UAC R655-4-11.3.2, Casing Joints - Steel Casing.

require.
3.4 Well Screen
The well was constructed using 30’ of Johnson stainless steel V-wire screen from 460’ –
490’. This well was screened in coarse-to-fine-grained sediments and a sieve analysis was
not conducted. Conducting a sieve analysis on drill cuttings from a rotary hole does not give
a representative analysis of the formation. In most cases an experienced driller can use his
experience in the area and information from local well logs to determine the best size
opening for the well. In this case, the size of the screen openings is likely not critical as many
U29130-WS001-Drilling Specifications-2024
-4-
February 14, 2024 Terakee Farms Water System Well 1
wells in the area have been perforated in place with openings up to ¼” in width. With no
gravel filter pack, there appear to be no issues with sediment infiltrating wells in the area.
3.5 Plumbness and Alignment Requirements
Current AWWA standards specify a deviation of no more than 2/3 the inside diameter per
100’, or in this case, no more than 5” per 100’. Methods for measuring plumbness include
gyro surveys and accelerometer/inclinometer instruments to log the deviation of the hole. It is
important to note that a well can fail this standard by having a more or less straight-line
deviation and not impact the performance of the pump or the annular seal. Oppositely, a well
can pass this standard and still not meet the annular space requirement or could negatively
impact the performance of a line-shaft pump if a relatively sharp crook, or dog leg were
present over a short span of the well. If the well fails to meet the requirements, it may still be
accepted if the misalignment does not interfere with the installation or operation of the pump
or uniform placement of the grout as stated in R309-515-6(6)(g)(ii). In this case, no action
may be required.
The well was not known to be tested for plumbness during drilling or after completion for
vertical alignment in accordance with AWWA Standard A100 by the selected driller.
Plumbness and alignment are not critical for a well designed to have a Grundfos 100S
submersible pump installed approximately 200’ deep, however, if the geologist or engineer
determines deviation will negatively impact the pump or grout placement, the well would
need to be abandoned and redrilled.
3.5.1 Centralizers
No centralizers were used. During seal emplacement, the well will be aligned by using the
drill rig, tremie rod, and visual inspection prior to and during the installation of the sanitary
seal and is the responsibility of the driller and seal witness certifier prior to and during the
installation of the sanitary seal. The casing may be adjusted using the drill rig, shim, or
centralizers at the discretion of the driller or well seal witness.
3.6 Gravel Pack
No gravel pack was installed in this well.
3.7 Grout Seal and Material
Grout and seal material shall meet the requirements of UAC R655-4-2 Definitions, and UAC
R655-4-11.4.2 Seal Material. Grout and seal material shall conform to the following
specifications. A grout seal from a minimum 105’ below ground surface is anticipated. . The
borehole must be at least 4” in diameter larger than the outside diameter of the casing to
provide the 2” annular space required for the grout seal. The seal will be witnessed by a
represented of DDW or other authorized individual who will provide a Well Seal Witness
Certificate to Terakee Farms and DDW. All construction on the well will cease for 72 hours
after seal is poured to allow the grout to properly cure.
3.7.1 Un-hydrated Bentonite
Dry sodium bentonite consisting primarily of granules, tablets, pellets, or chips that may be
placed in a well or borehole in the dry state and hydrated in place by either formation water
or by the addition of potable water into the well or borehole containing the dry
bentonite/montmorillonite.
U29130-WS001-Drilling Specifications-2024
-5-
February 14, 2024 Terakee Farms Water System Well 1
Unhydrated bentonite shall be used for plugs, sealing the pitless adaptor seal interval (if
installed) and the abandonment of wells. Unhydrated bentonite shall be furnished in sacks or
buckets from a commercial source and shall be free of impurities that adversely impact water
quality. Any pellet coating should be such that it retards the swelling of the pellets for a
minimum period of about 60 minutes.
Unhydrated bentonite can be placed below the annular seal (105’) when placed inside the
annulus of two casings, when placed using a tremie pipe, or by using a placement method
approved by the DWRi. The bentonite material shall be specifically designed for well sealing
and be within industry tolerances. All unhydrated bentonite used for sealing must be free of
organic polymers and other contamination. Placement of bentonite shall conform to the
manufacturer's specifications and instructions and result in a seal free of voids or bridges.
Granular or powdered bentonite shall not be placed under water by gravity feeding from the
surface. When placing unhydrated bentonite, a sounding or tamping tool shall be run in the
sealing interval during pouring to measure fill-up rate, verify a continuous seal placement,
and to break up possible bridges or cake formation.
3.7.2 Neat Cement Grout
Cement (Types I, II, III, V, high alumina, or a combination thereof) conforming to the ASTM
Standard C 150 (standard specification of Portland cement), with no more than six (6)
gallons of water per 94-pound sack (1 cubic foot) of sufficient weight density of not less than
15 lbs/gallon. One cubic yard of neat cement grout contains 1993 pounds of Portland cement
and not more than 127 gallons of clean water. To avoid gaps in the annular seal due to
bridging in wells with an annular opening of less than 4”, grout must be installed from the
bottom up using a positive displacement pump until the grout flows freely from the surface.
Grout additives to increase fluidity, bentonite, controlled density fill (CDF), fly ash shall not
be added to neat cement grout unless Utah Division of Drinking Water Director approval is
received.
3.7.3 Sand Cement Grout
A grout consisting of equal parts by volume of cement conforming to ASTM Standard Cl50
and clean sand/aggregate with no more than six (6) gallons of water per 94-pound sack (one
cubic foot) of cement. Sand cement grout may be used for annular openings of larger than 2-
inches.
3.7.4 Clay Seal
For annular openings greater than 6”, use of swelling bentonite seal meeting requirements of
R655-4-11.4.2.2 may be used if approved by the Director. Bentonite used to prepare grout for
sealing shall have the ability to gel; not separate into water and solid materials after it gels;
have a hydraulic conductivity or permeability value of 10E-7 centimeters per second or less;
contain at least 20% solids by weight of bentonite, and have a fluid weight of 9.5 pounds per
gallon or greater and be specifically designed for sealing.

3.8 Well Development
The well was previously developed by High Plains
Drilling and a step test was conducted. The step test
records are shown in table 1.
The next driller will conduct a pump test, the best
approach will be determined after the seal and pump is installed. If the well requires further
development, the following framework will be used. The actual methods and time needed
will be dependent on geology, hydrology, flow potential, amount of fine-grained material in
the formation, and drilling method.
3.8.1 Rig Development
This well was drilled using casing advance and air; therefore, no drilling fluids will need to
be removed from the formation and rig development is not required.
3.8.2 Pump Development
A pump without a check valve may be installed in the screened section. The well will first be
pumped at a very low flow rate until the water is clean at which time surge cycles
(rawhiding) will be conducted. The well will be surged 2 to 4 times then pumped for a
minimum one-hour or until the water clears up. Water levels, flow data, and sand content
from a Rossum sand tester may be recorded. After each surge cycle the flow will be turned
up slightly until maximum specific capacity or the maximum pump rate is reached. Water
levels will be monitored during this process to determine the efficiency of the well in place of
a step-test.
3.9 Pump Testing
All development data will be evaluated to determine the well efficiency or if additional time
or other methods are required. A constant rate test will be performed for at least 24 hours to a
week, or until stabilized drawdown has continued for at least six hours. The pumping rate
will be determined after development. The goal of the pump/aquifer test is to determine the
safe yield of the well and aquifer. Typically, in a valley fill well, 24 hours is sufficient,
however all data will be analyzed including the early time constant rate test to determine how
long the test will need to run.
The pump test shall include the following information:
• Pump curve of test pump
• State water level measured to the nearest 10th of one foot measured from identifiable
datum – usually top of casing
• Test pump intake depth
• Start time and stop
• For 10 uniform intervals for each log cycle record time in minutes since start of test,
pumping rate, and water level to nearest 10th of one foot from same datum as static
measurement
• Provide graphic evaluation on semi-log graph paper plotting drawdown
measurements on an arithmetic scale at locations corresponding to time since starting
test on logarithmic scale

Record time since stopping pump test in minutes at time intervals similar to those used
during constant-rate pump test after end of constant-rate test until there are no changes in
water level depth for a minimum of 6 hours.
3.10 Well Disinfection
Following the pump test and recovery period (recovery time dependent on data) and prior to
demobilizing from the site, the well shall be disinfected in accordance with UAC R309-5 15-
6(11) Well Disinfection and UAC R655-4- 11.6.5 Well Disinfection and Chlorination of
Water, using a solution of high-test sodium hypochlorite sufficient to establish a
concentration of 100 parts per million (ppm) chlorine residual throughout the well and shall
be left in the well a minimum of 8 hours.
Other well disinfection procedures may be approved by the Geologist, as long as they
conform to UAC R309-5 15-6(11) Well Disinfection and UAC R655-4-11.6.5 Well
Disinfection and Chlorination of Water.
The pump vendor shall not leave the site until approved by the Geologist.
3.11 Well Head Construction
The well is not in a designated flood zone (Appendix A). Upon completion of well
construction and rig development, the licensed driller shall extend the top of the well casing
to a minimum height of 18” above ground surface and be equipped with a tamper-resistant,
water-tight, locking casing cap or weld-on cap. If requested by the geologist, the well cap
shall have an access port to permit water level measurement with a water level meter or have
a transducer set. The access port shall be a minimum of l-inch diameter and have a water-
tight plug. Well head construction shall conform to the requirements of UAC R309-5 15-
6(6)(b) Permanent Steel Casing Pipe, R309-515-6(8) Capping Requirements, R655-4- l l.7.3
Completion or Abandonment, and R655-4-14.1 Temporary Abandonment.
