GROUNDWATER STUDY
WHITE MESA FACILITY
BLANDING,UTAH
PREPARED By
UMETCO MINERALS CORPORATION
PEEL ENVIRONMENTAL SERVICES
--,.JANUARY 1993
EXECUTIVE SUMMARY
(1)Umetco Minerals Corporation conducted additional groundwater studies for
the White Mesa facility during November-December,1992.
Four new borings were drilled and completed as monitoring wells.Two
wells were established upgradient and two downgradient of the facility.
(3)The borings encountered an average of 98 feet of very dry to dry
sandstones with claystone layers overlying a saturated zone in the Burro
Canyon Formation of limited thickness (average 26 feet).
•
(4)Some investigators (U.S.DOE consultants)consider water in the Dakota
Burro Canyon sequence not to be an aquifer because of its limited extent
and low hydraulic conductivity properties.(Naturita Tailings Remedial
Action Project)
(5)Travel times to the Burro Canyon saturated zone from pond releases have
been estimated based on analysis on the boring and well test data.
Travel times can be as short as a few weeks for joints directly in
contact with tailings solutions to 60+years for partially saturated
flow conditions.
(6)The chemistry of groundwater from the monitoring wells is extremely
variable,but all tend to be dominated by the sulfate ion.
(7)Use of a single monitoring well for background purposes appears to be
inappropriate.Time comparisons of a specific ion species (chlorides)
within specific wells is recommended for determining operational impacts
on the saturated zone in the Burro Canyon Formation.
(8)Statistical "T"tests (at the 0.05 level of significance)performed on
samples of chloride populations from specific wells over time show no
significant change in chloride concentrations.Some downgradient wells
analyzed do show a statistical significant decrease in the chloride ion
populations.

(9)The statistical analysis is confirmed by the chemistry of Cell 2 leak
detection system.
(10)Analyses of subsurface data collected from the present and past studies
and analysis of groundwater chemistry show that uranium recovery
operations at White Mesa have not affected the groundwater in the
saturated zone of the Burro Canyon Formation.

2.0 REGIONAL GEOLOGY
The White Mesa Mill is situated near the western margin of the
Blanding Basin in southeastern Utah.Thousands of feet of multi-colored marine
and non-marine sedimentary rocks have been uplifted and warped,and subsequent
erosion has carved a spectacular landscape for which the region is famous.
2.1 Physiography and Structure
The White Mesa Mill site is located within the Canyon Lands section of
the Colorado Plateau physiographic province (Figure 2.1-1).To the north,this
region is bounded by the Bookcliffs and Grand Mesa of the Uinta Basin;the
western margins are defined by the tectonically controlled high plateaus of the
Monument Uplift.The eastern boundary,less distinct,falls where the elevated
surface of the Canyon Lands section merges with the Southern Rocky Mountain
province.The southern boundary is arbitrarily defined as the San Juan River .
The Canyon Lands has undergone epirogenic uplift and subsequent
erosion which have produced the region's characteristic topography represented
by high plateaus,mesas,buttes,and deep canyons incised into relatively flat
lying sedimentary rocks of pre-Tertiary age.Elevations range from
approximately 3,000 feet in the bottoms of the deep canyons along the
southwestern margins of the region to more than 11,000 feet in the Henry,Abajo
and La Sal Mountains located to the north and northeast of the White Mesa Mill.
With the exception of the deep canyons and isolated mountain peaks,an average
elevation slightly in excess of 5,000 feet persists over most of the Canyon
Lands.
The Mill site is located near the western edge of the Blanding Basin,
which is situated east of the north-south trending Monument Uplift,south of
the Abajo Mountains and southwest of the northwest-trending Paradox fold and
fault belt.The southern boundary is defined by the Tyende Saddle and Carrizo
Mountains just south of the Utah-Arizona border.

Topographically,the Abajo Mountains are the most prominent feature in
the region,rising more than 4,000 feet above the broad,flat surface of the
Great Sage Plain.The Great Sage Plain is a structural slope,capped by the
resistant Burro Canyon Formation and Dakota sandstone.These strata lie almost
horizontal in an east-west direction,but dip to the south with a regional dip
of about 2,000 feet over a distance of nearly 50 miles.Though not as deeply
or intricately dissected as other parts of the Canyon Lands,the plain is cut
by narrow,vertical-walled south-trending valleys which range from 100 to more
than 500 feet in depth.
The strata underlying White Mesa have a regional dip of 1/2'to l'to
the south;however,local dips of 5'have been measured.Haynes,et al (1972)
includes a map showing the structure at the base of the Dakota Formation.No
faults have been mapped in the immediate vicinity of White Mesa.During an
investigation of the site a number of fracture attitudes were measured along
the rims of Corral and Cottonwood Canyons.Analysis of these data indicates
that there are two joint sets.The distance between the joints in each set
varies 5 to 20 feet.The primary joints strike from north-south to N20E with a
vector mean of N11E (Figure 2.1-2)and the secondary fractures have a strike
ranging between N40W to N60W with a vector mean of N47W (Figure 2.1-3).All
joint sets are near vertical to vertical.Only one small fracture was found in
the cores during recent drilling.However,this is to be expected in an area
of widely-spaced vertical joints.
2.2 Stratigraphy
Rocks of Upper Jurassic and Cretaceous age are exposed in the canyon
walls in the vicinity of the White Mesa Mill site (Figure 2.2-1).These rock
units include,in ascending order,the Salt Wash sandstone,the Recapture
shale,the Westwater Canyon sandstone and the Brushy Basin shale members of the
Upper Jurassic Age Morrison Formation.Overlaying these units are the
Cretaceous Age Burro Canyon Formation,Dakota sandstone,and erosional remnants

of Mancos shale.Erosional remnants of Mancos shale are only found north of
the Mill site.Eolian sand of Quaternary age and varying of thickness overlies
the Dakota sandstone and Mancos shale on the mesa,and alluvium,also of
Quaternary age,occurs in the bottoms of steam valleys.A thin deposit of
talus derived from rock falls of Dakota sandstone and Burro Canyon Formation
mantles the lower valley flanks.
A description of each stratigraphic unit at the project area,based on
borehole information,field reconnaissance and information provided by other
investigators follow:
Salt Wash Member -Medium to thick bedded,hard,gray to bluish-gray,
fine-to coarse-grained sandstone,fractured to slightly fractured in
the outcrop,interbedded with thinly laminated,hard,light
bluish-gray siltstone.This unit is approximately 105 feet thick.
Recapture Member -Thinly laminated,friable to well indurated,
yellowish brown to reddish-gray argillaceous siltstone,unfractured.
Interbedded with a 20-foot thick grayish brown sandstone layer which
pinches out to the south of the Mill site (D'Appolonia,1982).The
thickness of this unit is 120±feet.
Westwater Canyon Member -Thick bedded,well indurated,light grayish
green silty sandstone (fine-to corase-grained),fractured to slightly
fractured,fine-to coarse-grained,interbedded with thinly laminated
greenish-gray silty claystone and clayey siltstone.The thickness of
this unit is 50±feet.
Brushy Basin Member -Thinly laminated to medium bedded,soft to hard,
variegated claystone and siltstone,interbedded with thick lenses of
gray sandstone.Total thickness is approximately 300 feet.
Burro Canyon Formation -Thin cross-bedded,well indurated,light to
dark greenish-gray,gray and light brown sandstone occasionally
conglomeratic,interbedded with thick,soft,light greenish-gray,waxy
shale and siltstone.Thickness is 7S±feet.
2-8
Dakota Sandstone -Thin bedded,well indurated,light yellowish-brown,
poorly sorted,very fine-to medium-grained,kaolinitic,sandstone.
The thickness of this formation is GO±feet.
Mancos Shale -Light gray,thin bedded,soft,shale.Only random
occurring thin <5-foot thick remnants occur in the area north of the
mill site.
Eolian Sand -Reddish brown,very fine sand and silt,unconsolidated
to partially cemented with caliche,approximately 20 feet thick.In
some areas,particularly south of the Mill site,a 3-to 6-inch layer
of caliche was encountered at a depth of 5 feet.
Talus and Colluvium -Sandstone rock fall debris,talus and slope
wash,sizes range from cobbles to massive blocks derived from Dakota
sandstone and Burro Canyon Formation.Talus is commonly incorporated
with clay and silt slopewash,forming a matrix of angular sandstone
cobbles mixed with inner materials and containing numerous voids.
Thickness of this unit varies considerably,probably from zero to a
maximum of 20 feet (D'Appolonia,1982).
Alluvium -Soft,reddish-brown to yellowish-brown sandy silt with
lenses of loose sandy gravel,slightly calcareous.

3.0 HYDROGEOLOGY
3.1 Regional Hydrogeology
The regional occurrence and distribution of groundwater in the project
area are controlled by the type and extent of rock formations and the
structural features of the Canyon Lands section of the Colorado Plateau
Physiographic Province.
An intricate system of deep canyons along and across hogbacks and
cuestas has resulted from faulting,upwarps and dislocation of rocks around the
intrusive rock masses such as Abajo Mountains,approximately 25 miles to the
north of the project site.Thus,the region is divided into numerous
hydrological areas controlled by structural features such as the San Rafael
Swell,the Monument Upwarp,and the Abajo,Henry and La Sal Mountains,as well
as the faulted anticlines in Salt,Spanish and Lisbon Valleys.
Water-bearing sedimentary rock formations of Cambrian and Devonian
through Cretaceous age are exposed in the region or have been identified in the
Blanding Basin.
3.1.1 Bedrock Aquifers
'-.
Regionally,the formations that are recognized as bedrock aquifers are
the Cretaceous-age Dakota sandstone and sandstones within the upper part of the
Morrison Formation of late Jurassic age;the Bluff,the Entrada and the Navajo
sandstones of Jurassic age;the Wingate sandstone and the Shinarump member of
the Chinle Formation of Triassic age,and the DeChelle member of the Cutler
Formation of Permian age.These units are shown in Figure 3.1.1-1,a
general ized section of stratigraphic units showing the fresh water-bearing
units in southeastern Utah.

Other formations within this sequence also contain water but its
quality varies from slightly saline to very saline.Beneath the Permian,
Cutler Formation are saline water-bearing units within the Rico and the Hermosa
Formations of Pennsylvanian age from which oil is produced in the Blanding
Basin.Hydrogeologic data on the formations in the area are limited.
The Bl uff sandstone,found on 1yin southern San Juan County,has
reportedly yielded 13 and 25 gpm in two wells drilled near Bluff (Feltis,
1966).The Entrada sandstone is reported to yield an average of 143 gpm at
five wells drilled in San Juan County,but yields as high as 1200 gpm have been
reported in other areas of southeast Utah (Feltis,1966).
The Navajo sandstone is one of the most permeable bedrock aquifers in
the region with reported yields as high as 1335 gpm (Feltis,1966),although
many wells drilled into the Navajo in southeast Utah only have yields varying
between 35 to 72 gpm.The Umetco/Energy Fuels industrial well drilled into the
Navajo sandstone is reported to have yielded 120 gpm after 1.5 hours of pumping
shortly after it was drilled.
Throughout the area,small quantities of water are produced from
shallow wells constructed in the alluvium that occurs in stream valleys and as
a veneer on the flattop mesas.These wells are subject to great seasonal
variation in yield and the water withdrawn is generally of poor quality.
3.1.2 Regional Recharge
The source of recharge to bedrock aquifers of the region is
precipitation.Precipitation in southeastern Utah is characterized by wide
variations in seasonal and annual rainfall and by long periods of deficient
rainfall.Short duration summer storms furnish rain in small areas of a few
square miles and this is frequently the total rainfall for an entire month
within a given area.The average annual precipitation in the region ranges
from less than 8 inches at Bluff to more than 16 inches on the eastern flank of
the Abajo Mountains,as recorded at Monticello.The mountain peaks in the
•
3-4
Henry,La Sal and Abajo Mountains may receive more than 30 inches of
precipitation,but these areas are very small in comparison to the vast area of
much lower precipitation in the region.
Recharge to bedrock aquifers in the region occurs by direct
infiltration of precipitation into the aquifers along the flanks of the Abajo,
Henry and La Sal Mountains and along the flanks of the folds,such as Comb
Ridge Monocline and the San Rafael Swell,where the permeable formations are
exposed at the surface.Recharge also occurs on the wide expanses of flat
lying beds that cap the mesas between these major structural features.In
these cases,some precipitation has been to percolate through the near surface
joints,fractures and intergranular porosity in the shales and sandstones.
3.2 Groundwater Use
Forty groundwater appropriation applications,within a five-mile
radius of the Mill site,are on file with the Utah State Engineer's office.
The location of the applications is shown on Figure 3.2-1 and is listed on
Table 3.2-1.The majority of the applications are by private individuals and
are for wells drawing small quantities of water,less than S gallons per minute
(gpm),from the Surro Canyon Formation.For the most part,these wells are
located upgradient (north)of the White Mesa Mill site.Stockwatering and
irrigation are listed as primary use of the majority of the wells.(Studies by
consultants performed at the U.S.Department of Energy's disposal site at
Naturita also note that the Dakota sandstones,Burro Canyon Formation and upper
sandstones of the Brushy Basin member are not considered an aquifer due to the
low permeability,discontinuous nature and limited thickness of these units.)
Union Carbide and Plateau Resources have appropriation applications on file for
deep wells (Entrada Formation)capable of much larger volumes of water
production for industrial use.
Two water wells exist approximately 4.5 miles southeast of the site on
the Ute Indian Reservation.These wells supply domestic water for the village
on the mesa along Highway 191.Both wells are completed in the Entrada
sandstone which is 1500±feet below the ground surface.

SUBSURFACE CONDITIONS
General
4-1
The subsurface conditions at the White Mesa facility have been
previously investigated by Dames &Moore (1978),D'Appolonia (1980),and Chen &
Associates (1978).Monitoring wells have been previously installed by
D'Appolonia and Sampson &Associates.
This investigation consisted of drilling four new borings (WMMW-16
through WMMW-19).The physical and hydrogeological properties of the bedrock
were evaluated by performing field aquifer and laboratory tests on core
samples.
4.2 White Mesa Stratigraphy
The lithology of the bedrock at White Mesa was verified by drilling
four new borings to depths from 95 to 150 feet below the eXisting ground
surface.
The generalized stratigraphy through White Mesa (Figure 4.2-1)is
shown on Figures 4.2-2 and 4.2-3.The description of the drilling process and
boring logs is shown in Appendix A.All of the borings were drilled through
the Dakota/Burro Canyon Formations and were terminated in the Brushy Basin
member of the Morrison Formation.The boring log descriptions are based on
visual descriptions of air rotary cuttings and core samples.The contacts
between the different rock types or beds are based on examination of samples,
gamma-ray logging and drilling characteristics.It was apparent from drilling
and logging that the physical characteristics of the bedrock materials vary
considerably,both vertically and laterally.This refl'ects the nature of the
fluvial and coastal plain depositional environments in which they were
deposited.

4.2.1 Dakota Formation
4-5
Directly below 3 to 6 feet of very silty clays to clayey silts and
silts,the borings penetrated the Dakota Formation at depths of 43 to 66 feet
(elevations 5572 to 5518 feet)below the surface.The Dakota at this site is
typically composed of moderately hard to hard sandstones with random
discontinuous shale (claystone)and siltstone layers.The sandstones have beds
varying from a few inches to 10 feet in thickness and are occasionally cross
bedded.The sandstones are moderately cemented (upper part of formation)to
well cemented with kaolinitic clays.The porosity of the Dakota is
predominately intergranular.Laboratory tests performed (see Table 4.2-1)show
the total porosity of the sandstones varies from 13.4 to 26.0 percent with an
average value of 19.9 percent.The effective porosity of the formation is
estimated to be 15.0 percent.The formation is very dry to dry with volumetric
water contents varyin9 from 0.6 to 7.1 percent with an average value of 3
percent.Saturation values for the sandstones vary from 3.7 to 27.2 percent.
The claystones and siltstones are typically 2 to 3 feet thick.Boring WMMW-19
encountered a siltstone layer having a thickness of 8 feet at a depth of 33 to
41 feet.No groundwater or perched water conditions were found in drilling of
the four borings in the Dakota Formation.
4.2.2 Burro Canyon Formation
Previous investigators have made no distinction between the Dakota and
Burro Canyon Formations.However,examination of borehole cuttings,cores and
geophysical logging methods has allowed separation of the two formations for
analysis purposes.Directly below the Dakota Formation,the borings
encountered sandstones and random discontinuous shale layers of the Burro
Canyon Formation were found to extend to depths of 91 to 141 feet (elevation
5509 to 5421 feet).

Although similar to the Dakota,the Burro Canyon Formation varies from
a very fine-to coarse-grained sandstone.The sand grains are generally poorly
sorted.The coarse-grained layers also tend to be conglomeratic.The grains
are cemented with both silica and kaolin but the silica cemented sandstones are
prominent.The formation is extremely argillaceous near the contact with the
Brushy Basin member of the Morrison Formation.
Based on the core samples tested,the sandstones of the Burro Canyon
Formation vary in total porosity from 1.7 to 27.6 percent;the average being
16.0 percent.Volumetric water content in these sandstones ranges from 0.1 to
7.1 percent,averaging 2.2 percent,with the fine grained materials having the
higher moisture content.Porosities in the claystone layers vary from 16.4 to
29.I percent with saturation values ranging from 33.8 to 77.2 percent.A
perched 9roundwater table was found at the base of the Burro Canyon Formation.
•4.2.3 Brushy Basin Member
Each of the borings penetrated the Burro Canyon Formation and was
terminated within the Brushy Basin member of the Morrison Formation.The
borings encountered moderately plastic dark green to dark reddish-brown
mudstones of medium consistency.

5.0 SITE GROUNDWATER
5.1 Occurrence
At White Mesa a vadose (unsaturated)zone occurs to depths of
approximately 73 to 109 feet.Fluids in this zone are held in the bedrock
pores under negative pressure conditions.The saturated (groundwater)zone
occurs as discontinuous perched water within the Burro Canyon Formation at its
contact with the Brushy Basin member of the Morrison Formation.The Brushy
Basin member acts as an aquitard to ,vertical flow.Figures 5.1-1 and 5.1-2
show the depth of thickness of both the vadose and saturated zones below the
site.Table 5.1-1 is a list of monitor wells constructed at White Mesa to
monitor the saturated zone.Table 5.1-2 shows the data obtained from the
existing and new observation wells.
5.1.2 Aquifer Tests
As part of this investigation,all existing monitor wells and the new
wells (where feasible)were tested to determine hydrogeological properties.
The existing wells were pumped at extremely low rates to extend the test
duration as long as possible.Methods developed by Strausberg (1982)(see
Appendix C)were used to determine bedrock permeability values in the tight
formations.Injection tests were performed in three wells because of the
extremely low permeability of the bedrock.The recent test results compare
favorably with the work done by Hydro-Engineering in 1991.Field permeability
tests by the Bureau of Reclamation method E-18 were performed both in the
unsaturated and saturated zones to determine rock permeability in the new
borings.Wells completed in these borings will be developed and pump-tested at
a later date.Weather conditions prevented these activities in December,1992.
A description of the aquifer tests performed in each respective
boring,and/or completed well with the test results is presented in Appendix C.
The results are also summarized in Tables 5.1.2-1 and 5.1.2-2.For the pump
tests,hydraulic conductivity values have been corrected for the portion of the
plotted wells below the shales of the Brushy Basin member of the Morrison
Formation.

Groundwater Water Movement
Vadose Zone
5-8
•
Fluid movement in the vadose zone (Dakota Formation)occurs
principally in the vertical direction from the driving forces of both capillary
pressure gradients and gravity.When seepage occurs through a nearly dry
foundation material,as is the case at White Mesa,the capillary gradients act
in the same direction as gravity and the rate of downward flow is enhanced.
Capillary gradients,however,are most important in the vicinity of the
"wetting front."As seepage proceeds,the driving force due to gravity becomes
increasingly important relative to capillary pressure.In the horizontal
direction,the gradient of capillary pressure is the only driving force.Just
as in the vertical direction,the capillary gradients decrease as the seepage
spreads laterally .
When the wetting front encounters a layer with smaller pore size and
lower permeability,the invading fluid is readily absorbed.There is,however,
a corresponding decrease in the capillary gradient as the tight layer wets up
and gravity becomes the dominant driving force.The maximum flux that can be
sustained by gravity alone is that which is equal to the permeability of the
layer.If the seepage rate from the impoundment is greater than the
permeability,water will perch on the tight layer.
The permeability of the strata relative to the seepage rate is of
critical importance to the question of whether or not perched water will
develop.Field measurements of permeability indicate that the permeability of
the tightest layers (claystones)within the Dakota Formation is about 1.0 x
10-7 cm/s (0.1 ft/yr).Downward flow from net infiltration in the current
natural state is expected to be much,much smaller than 0.1 ft/yr.Therefore,
it is to be expected that no water perched on the claystones would be
encountered,as indeed,is the case.Assuming that natural,net infiltration
is 5 percent of precipitation,a layer with permeability of 0.05 ft/yr,or
less,would be required to cause sustained perched water to occur.The fact
5-9
that no perched water was encountered in drilling the four new borings suggests
that the permeability of the claystone layers present in the formation have a
permeability greater than 0.05 ft/yr.It is believed that the most reasonable
value for permeability of the mudstone layers is about I x 10-7 cm/s (0.1
ft/yr),but it may range downward to perhaps 5.0 x 10-8 cm/s (0.05 ft/yr).
Considering the above,travel times for partially saturated flow
through the vadose zone to the Burro Canyon can be estimated based on estimated
infiltration rates of permeability and water content of the formation.
Assuming an average volumetric water content of 3 percent,the velocity through
the Dakota sandstone is estimated to range from 1.7 to 3.3 feet per year.
Taking the average depth to the saturated zone as 98 feet,it would take
apprOXimately 29 to 57 years for pond seepage to reach the perched water table
in the Burro Canyon Formation.In the absence of shale layers,the McWhorter-
Nelson model predicts a travel time of 15.0 years for (pond)seepage to reach
the water table.This analysis is valid for parts of the site where the
discontinuous lenticular claystones do not exist.Considering the variability
of the strata,more refined estimates would be pointless.
If pond leakage occurred,there is a possibility that seepage under
positive pressure could be in direct contact with vertical joints at the base
of the ponds.For this condition,seepage would occur as localized saturated
flow through the joints within the Dakota into the Burro Canyon.For this
case,the travel time to the saturated zone is difficult to estimate but could
be on the order of a few weeks to months.
5.2.2 Saturated Zone
The groundwater in the Burro Canyon Formation exists as an unconfined
perched water body on top of the Brushy Basin member.Its occurrence is
discontinuous and hydraulic conductivity values determined from tests are low
to extremely low (see Table 5.1.2-1).Consequently,based on the low hydraulic
conductivities and extent of the saturated zone,it is not considered to be a
viable aquifer in the immediate project area.
5-10
Water movement within this zone is in a south-southwest direction,the
same as the dip of the bedrock strata.Using an average hydraulic conductivity
value of 0.7 feet per day,an effective porosity of 15 percent,and an average
hydraulic gradient of 0.01 foot/foot,the average velocity of groundwater
movement is 0.047 feet per day (17 feet per year).Hydro-Engineering (1991)
estimated an average groundwater movement rate of 44 feet per year in the
saturated zone in the vicinity of the tailings cells.For a saturated
thickness of 26 feet and a length of 3,500 feet across the mesa,the flow rate
through the saturated zone of the Burro Canyon is 22 gallons per minute.
5.3 Water Quality
Groundwater monitoring has been conducted at the White Mesa facility
since 1979.Table 5.1-2 presented previously shows a list of wells that has
been constructed for monitoring purposes at White Mesa.The water quality data
obtained from these wells are shown both in tabular and graphical form in
Appendix B.
Comparisons of the water chemistries from the various wells were
analyzed by graphical techniques.The trilinear plot and the Stiff diagram
were used in "fingerprinting"site groundwater and differentiating the
groundwater from different sources or wells.The trilinear plot is a graphical
technique (Figure 5.3-1A)in which the percentage composition of the major
anions and cations in a water sample is plotted onto triangular plotting
fields.The resultant plotting positions are then projected into a central
plotting diamond,defining the sample's composition.The plot is so designed
that mixtures of water are shown by progression along a straight line
connecting the plotted points of both waters in the central plotting diamond.
Thus,the trilinear plot is extremely useful in determining the percentage
mixtures,based on the major ion compositional profile of the two-end point
solutions.

The Stiff diagram is a "signature"formed by plotting the relative
percentage of major cations to the left of a central axis and the anions to the
right of the central axis and connecting the plotted points.In the computer
mapping program utilized,the cations are plotted in the order of sodium plus
potassium,calcium,and magnesium to the left of the central axis.The anions
are plotted in the order of chloride,carbonate plus bicarbonate,and sulfate
to the right of the central axis.Such a graphical signature is useful in
making visual comparisons of various water chemistries.
Figure 5.3-1 is a trilinear plot for the water sampled in wells in the
immediate vicinity of the Mill site during the fall of 1992.Figures 5.3-2
through 5.3-4 are Stiff diagrams presenting the same data.It can be seen from
these plots that the water from all well s is of the sulfate (anion type).The
cation definition of the water type is extremely variable.Of the thirteen
wells analyzed for water chemistry four fall in the calcium-sulfate type
category,four fall in the (sodium plus potassium)-sulfate type,two samples
classify in the magnesium-sulfate type.Five samples have no dominant cation
type.These five samples tend,however,to classify close to the (sodium plus
potassium)-sulfate and calcium-sulfate types.
A time sequence change of water chemistries from four sampling periods
for wells WMMW-l,WMMW-2 and WMMW-3 using the trilinear plotting technique is
shown in Figures 5.3-5 through 5.3-7.These figures present the change in
water chemistries from October,1979 through February 1991.The change in
water chemistry is attributed to initial incomplete cleaning of wells,
groundwater variation,laboratory analytical errors or a combination.The data
for 1979 appears to be suspect with respect to providing an accurate
representation of the groundwater chemistry.This is probably due to
incomplete cleaning of the well after drilling and prior to the first sample.

Comparison of well chemistries to a common background well (chemistry)
will not provide correct information on the possible effects of pond seepage on
groundwater.However,by evaluating the possible chemical change of a specific
ionic species within individual wells over time is plausible.The statistical
"T"test was performed on samples from chloride populations within specific
wells over time (see Appendix E).Because chlorides are a conservative species
and are concentrated in the tailings solutions,analyses using this parameter
offers the best method of detecting detrimental changes to the groundwater.In
addition,information on Cell 2 leak detection system chemistry provides a
useful picture of the water chemistry directly below Cell 2.The following is
a discussion of the analyses.
Cell 2 Leak Detection System -The water found in Cell 2 leak
detection system (LOS)contains the lowest total dissolved solids
(ToS)content (756 mg/l)of any water sampled in the area (Figure
5.3-1).Excepting the Jones wells,it also contains the highest
percentage of carbonate and bicarbonate when compared to the other
monitoring wells.The slimes drain contains a ToS value of 47,115
mg/l and no carbonates due to its extremely low pH (typically 1.5
to 3).Any leakage of tailings solution into the LOS would react with
the carbonates and raise the ToS levels which has not occurred to
date.
WMMW-I (Installed September 1979)-This well was originally chosen as
the background well for the site.It is believed that improper well
completion and/or analytical errors gave erroneous chemistry values
for this well in 1979 (see Figure 5.3-5).Chlorides in this well have
been relatively low (varying from II to 53.2)since 1980.
A "T"test was performed on sample population from 1980-81 to a sample
population from 1990-92.The tests indicate that there is a
significant difference in the mean of the populations at the 0.05
level of significance.Statistically,the chloride levels are shown
to have decreased significantly.Tests performed on a sulfate
population from the period 1980-81 to a population from 1990-92 show
the sulfates in this well have significantly increased.
•
5-22
WMMW-3 (Installed September 1979)-This well was originally
constructed to serve as the "point of compliance well",Statistical
testing ("T"test)on a chloride population from 1980-81 compared to a
chloride population from 1990-92 shows that there is no significant
difference in the two chloride populations.Sulfate samples taken
1980-81 compared to samples taken 1988-91 show there is a significant
increase in sulfates.
WMMW-5 (Installed May 1980)-Statistical tests ("T"test)performed
on a sample from the chloride population (1981-83)to a sample from a
chloride population (1990-92)shows there is a significant difference
in the means of the chloride populations and that the chloride content
has decreased.
WMMW-I2 (Installed December 1982)-The statistical "T"test performed
on a sample from the chloride population from 1982-85 compared to the
chloride population from 1990-91 shows there is a significant
difference in the means of the chloride populations of these two
sampling periods and that the chloride content has decreased.
WMMW-14 and 15 (Installed September 1989)-These monitor wells were
installed in the south embankment of Tailings Cell No.3 in 1989.
Wells 14 and IS have similar water chemistry as monitor well 12 which
was installed in 1980 (see Figures 5.3-1 and 5.3-3).A statistical
"T"test performed on samples from a chloride population from November
1989 through November 1992 show wells 14 and 15 to have different mean
population values from 12 and they are significantly lower than the
mean chloride population of well 12.Since well 12 has had a
significant decrease in chloride content,it is likely that the
groundwater chemistry in the vicinity of these wells has undergone
similar changes.Analyses of these wells also show a decrease in
chlorides since 1989-90 to 1990-91.

5.4 Impact of Operations on Groundwater
Uranium recovery operations at White Mesa has produced tailings
solutions wit high concentrations of sulfates and chlorides.Using the
chloride ion to track changes in groundwater chemistry is the most feasible
method to detect changes in groundwater chemistry.To date,all indications
show that operations at White Mesa have not impacted the saturated zone of the
Burro Canyon Formation.

DRILLING AND WELL CONSTRUCTION PROCEDURES
DRILLING
Four new observation wells were drilled and constructed at the White
Mes a Mi 11 site duri ng November and December,1992.
Twelve-inch borings were drilled to a depth of 19.5 feet for each of
the new monitor wells.Steel surface casing 10-inch in diameter and 0.25-inch
thick was set to this depth and cemented into place with a cementlbentonite
9rout and allowed to set up for 72 hours.
WMMW-16 was cored to total depth using an HQ diamond bit with an outer
diameter of 4.25 inches.Once the total depth was achieved,the well was
reamed using a 7 7/8-inch tricone bit.Ten-foot,2.34-inch cores were obtained
during each .
WMMW-17,-18 and -19 were drilled in a similar manner as WMMW-16
except these wells were not cored over the total depth of the hole.Once the
surface casing was set,the borehole was drilled down to the first core point
using a 7 7/8-inch tricone bit.(Drilling was conducted with air using small
quantities of water from the White Mesa Culinary Well to keep the cuttings
moist and reduce dust.)A 10-foot core was obtained using the equipment
described for WMMW-16.Upon completion of the coring,the hole was then reamed
with the tricone bit and drilled down to the next core point.It should be
noted that core recoveries in WMMW-17,-18 and -19 are well below the 100
percent recoveries achieved in WMMW-16.The low core recovery rate in these
boring is due to the following conditions:
•
-2-
Each new core run was started in an 8-inch hole which allowed the
barrel and pipe to wobble in the hole resulting in the core not
being held firmly in the core catcher as it was cut.
-In order to recover an uncontaminated core,the driller was not
allowed to use a "core-loss polymer"which would have enhanced
recovery.
The drill rig,bit and pipe were decontaminated upon completion of
each hole,prior to moving to the next location.
WELL DEVELOPMENT
Once the borehole had been logged,the well was developed by jetting
the groundwater and residual cuttings out of the borehole,then allowing the
well to partially recover,then jetting once again.This was repeated until
all the cuttings were removed and the water was clear.
WELL CONSTRUCTION
Each observation well was constructed using 4-inch flush-joint
schedule 40 PVC pipe,20-slot (0.02-inch)was used for the slotted section,10
-20 Colorado silica sand gravel pack,bentonite pellets,and cement/bentonite
grout.A cap was placed on the bottom of the 4-inch PVC-riser pipe.This was
followed by an interval of blank PVC pipe to act as a sump for the well.A
screened interval was placed above of the sump,followed by blank PVC pipe to
surface.A gravel pack was then placed between the 4-inch PVC pipe and the
wall of the borehole from the bottom of the hole to a selected point above the
slotted portion of the PVC pipe.Five feet of bentonite pellets were then
placed above the gravel pack.Bentonite/cement grout was placed from the top
of the bentonite pellet seal to surface.PVC caps were then placed on the pipe
and a locking cap constructed on the steel casing.
