1. INTRODUCTION
This report describes the installation, development, and hydraulic testing of perched monitoring
wells MW-38, MW-39 and MW-40 at the White Mesa Uranium Mill (the “Mill” or the “site”)
near Blanding, Utah. The three wells were installed far to the southeast of the tailings
management system as shown on Figure 1. All three wells were installed as required by the
January 19, 2018 Groundwater Discharge Permit. These wells are located far to the southeast
(cross-gradient) of the tailings management system.
All three wells were installed during the week of February 12, 2018. Development consisted of
surging and bailing (during February and March, 2018) followed by overpumping (during
March, 2018). Hydraulic testing consisted of slug tests conducted during the week of March 19,
2018.

2. DRILLING AND CONSTRUCTION
Well installation procedures were similar to those used previously at the site for the construction
of other perched zone wells (Hydro Geo Chem, Inc. [HGC], 2005). Drilling and construction
were performed by UCOLO Drilling, LLC, and borings logged by Mr. Lawrence Casebolt under
contract to Energy Fuels (USA) Corporation (EFRI). As-built diagrams for the well construction,
based primarily on information provided by Mr. Casebolt, are shown in Figures 2 through 4. The
depths to water shown in the as-built diagrams were based on water level measurements taken
just prior to development (in feet below land surface). New wells were surveyed by a State of
Utah licensed surveyor and the location and elevation data are provided in Table 1.
2.1 Drilling and Logging Procedures
All borings were drilled by air rotary using tricone bits. Drill cuttings samples for all borings
were collected at 2½-foot depth intervals and placed in labeled, zip-sealed plastic bags and
labeled plastic cuttings storage boxes Copies of the lithologic logs submitted by Mr. Casebolt are
provided in Appendix A.
For each well an 11-inch diameter tricone bit was used to construct borings of sufficient diameter
to install 8-inch-diameter, Schedule 80 poly vinyl chloride (PVC) surface (conductor) casings.
The surface casings extended to depths of approximately 9 feet below land surface. Once the
surface casings were in place, the boreholes were drilled by air rotary (and foam as needed)
using a 6¾ inch diameter tricone bit. The boreholes penetrated the Dakota Sandstone and the
Burro Canyon Formation and terminated in the Brushy Basin Member of the Morrison
Formation.
Although not specifically noted in the lithologic log, drilling fluid return from the lowermost
portion of the MW-39 borehole (near the contact between the Burro Canyon Formation and
underlying Brushy Basin Member) had a reddish color and sheen. This color change may be due
to the change in color from the light-colored sandstone of the Burro Canyon Formation to the
purplish-brown to red shale within the uppermost portion of the Brushy Basin Member; however,
both the color and sheen may also indicate the presence of iron bacteria. If present in the
formation, iron bacteria are expected to influence the chemistry of the perched groundwater
collected from this well.
Pyrite in the MW-39 borehole was also noted at the contact between the Burro Canyon
Formation and underlying Brushy Basin Member (as noted in the lithologic log) and is also

expected to impact the chemistry of the perched groundwater collected from this well. The
influence of pyrite in the perched groundwater zone is discussed in HGC (2012).
2.2 Construction
The wells were constructed using 4-inch diameter, Schedule 40, flush-threaded PVC casing and
0.02-slot, factory-slotted PVC screen. Colorado Silica Sand was used as a filter pack and
installed to depths of approximately 4 to 6 feet above the screened intervals. The annular spaces
above each filter pack were sealed with hydrated bentonite chips. Well casings were fitted with
4-inch PVC caps to keep foreign objects out of the wells and lockable steel security casings were
installed to protect the wells.
2.3 Development
Wells were developed by surging and bailing followed by overpumping. Development records
are provided in Appendix B.

3. HYDRAULIC TESTING
Hydraulic testing consisted of slug tests conducted by HGC personnel using a methodology
similar to that described in HGC (2005).
3.1 Testing Procedures
The 3-foot long slug used for the tests in MW-39 and MW-40, which displaced approximately 3/4
gallons of water, is described in HGC (2002). Due to the small saturated thickness at MW-38, a
shorter (approximately 1 ½ foot long) slug displacing approximately 0.36 gallons, was used for
the test at that well. Both slugs consisted of sealed, pea-gravel-filled PVC pipe; the 3-foot long
slug used schedule 80 PVC and the 1 ½ foot long slug used schedule 40 PVC.
Level TrollTM 0-30 pounds per square inch absolute (psia) data loggers were used for the tests.
The Level Trolls were deployed below the static water column of the tested wells and used to
measure the change in water level during the test. A 0-30 psia Baro-TrollJ was used to measure
barometric pressure and was placed in a protected environment near the wells for the duration of
the testing. Automatically logged water level data were collected at 3-second intervals and
barometric data at 5-minute intervals.
Prior to each test, the static water level was measured by hand using an electric water level meter
and recorded in the field notebook. The data loggers were then lowered to a depth of
approximately ten feet below the static water level in each well except MW-38. Because the
water column height in MW-38 was only approximately 6 feet, the logger was lowered to the
base of the well casing. Background pressure readings were then collected for approximately 1 to
3 hours prior to beginning each test. The purpose of collecting the background data was to allow
correction for any detected water level trends.
Once background data were collected, the slug and electric water level meter sensor were
suspended in the tested well just above the static water level. Each test commenced by lowering
the slug to a depth of approximately two feet below the static water level over a period of a few
seconds and taking water level readings by hand as soon as possible afterwards. Hand-collected
data recorded in the field notebook were obtained more frequently in the first few minutes when
water levels were changing more rapidly, then less frequently as the rate of water level change
diminished. Upon completion of each test, automatically logged data were checked and backed
up on the hard drive of a laptop computer.

3.2 Hydraulic Test Data Analysis
Data from each test was analyzed using AQTESOLVETM (HydroSOLVE, 2000), a computer
program developed and marketed by HydroSOLVE, Inc. In preparing the automatically logged
data for analysis, the raw data were converted to displacements and the total number of records
was reduced. All data collected in the first 30 seconds (except for a negative displacement caused
by initial water level oscillation) were retained, then every 2nd, then 3rd, then 4th, etc. record
was retained for analysis. For example, if the first 10 records were retained (30 seconds of data at
3-second intervals), the next records to be retained would be the 12th, the 15th, the 19th, the
24th, etc.
Data were analyzed using two solution methods: the KGS unconfined method (Hyder et al.,
1994) and the Bouwer-Rice unconfined method (Bouwer and Rice, 1976). When filter pack
porosities were required by the analytical method, a value of 30 percent was used. The saturated
thicknesses were taken to be the difference between the depth of the static water level measured
just prior to each test and the depth to the Brushy Basin Member contact as defined in the drilling
logs (Appendix A). The static water levels were below the tops of the screened intervals in all
three wells and the saturated thicknesses were taken to be the effective screen lengths.
An increase in barometric pressure during the test at MW-39 appeared to influence the
automatically-logged data, and the displacements calculated from that data were corrected
accordingly. Figure 5 compares corrected and uncorrected water level displacements for
automatically logged data at MW-39. Corrections did not need to be applied to displacements at
MW-38 and MW-40.
The KGS solution allows estimation of both specific storage and hydraulic conductivity, while
the Bouwer-Rice solution allows estimation of only the hydraulic conductivity. The Bouwer-
Rice solution is valid only when a straight line is identifiable on a plot of the log of displacement
versus time (indicating that flow is nearly steady), and is insensitive to both storage and the
specified initial water level rise. Generally, only the later time data are interpretable using
Bouwer-Rice. In analyzing data from MW-40, near-straight line portions of middle and late-time
data were both analyzed.
The KGS solution accounts for non-steady flow and storage, is sensitive to the specified initial
water level rise, and generally allows a fit to both early- and late-time data. Both KGS and
Bouwer-Rice solutions were used for comparison. Automatically logged and hand-collected data
were analyzed separately using both solution methods. The hand-collected data therefore served
as an independent data set and a check on the accuracy of the automatically logged data.

Table 2 summarizes test parameters and Table 3 and Appendix C provide the results of the
analyses. Appendix C contains plots generated by AQTESOLVETM that show the quality of fit
between measured and simulated displacements, and reproduce the parameters used in each
analysis. Appendix D provides both raw and corrected displacement data. Estimates of hydraulic
conductivity range from approximately 1.8 x 10-5 centimeters per second (cm/s) to 1.3 x 10-4
cm/s using automatically logged data, and from approximately 1.4 x 10-5 cm/s to 2.1 x 10-4 cm/s
using hand-collected data. Estimates are within the middle portion of the range previously
measured at the site (approximately 2 x 10-8 cm/s to 0.01 cm/s).
In general, there is good agreement between estimates obtained from the two solution methods
and between estimates obtained from automatically logged and hand-collected data. All
estimates are within a factor of two, except for the late-time Bouwer-Rice estimate for MW-40,
which was a factor of 3 lower than the highest estimate for that well (using automatically logged
data). Although there was generally good agreement between the KGS and Bouwer-Rice results,
because the KGS solution accounts for non-steady flow and aquifer storage, the results obtained
using KGS are considered more representative than those obtained using Bouwer-Rice.

4. CONCLUSIONS
Procedures for the installation, hydraulic testing, and development at new perched monitoring
wells MW-38, MW-39 and MW-40 are generally similar to those used previously at the site for
the construction, testing, and development of other perched zone wells.
Automatically logged and hand-collected slug test data from new wells were analyzed using
KGS and Bouwer-Rice analytical solutions. Estimates of hydraulic conductivity range from
approximately 1.8 x 10-5 centimeters per second (cm/s) to 1.3 x 10-4 cm/s using automatically
logged data, and from approximately 1.4 x 10-5 cm/s to 2.1 x 10-4 cm/s using hand-collected data.
Estimates are within the middle portion of the range previously measured at the site
(approximately 2 x 10-8 cm/s to 0.01 cm/s).
