I. SUMMARY OF FINDINGS
-------
I. SUMMARY OF FINDINGS
I. Three principal and three secondary aquifers are identified
by this report in the Laramie, Shirley, and Hanna basins, Wyoming.
The principal aquifers include the (1) Tertiary, (2) Cloverly, and
(3) Casper-Tensleep. Secondary aquifers include the (1) Mesaverde,
(2) Frontier, and (3) Sundance.
In addition, there are numerous local ground-water systems.
Local ground-water systems as defined here are generally discontinuous
and unconfined. They include (1) partially saturated elevated and
highly dissected outcrops, (2) saturated sandstones having limited
areal extent, and (3) saturated alluvium.
Recharge to the principal and secondary aquifers occurs by (1)
infiltration of precipitation into outcrops, (2) leakage of water
from adjacent units, and (3) stream losses into permeable outcrops.
Recharge to local ground-water systems occurs by direct infiltration
of precipitation into outcrops and by stream losses into permeable
units.
II. The permeabilities of the rocks in the area are locally
dominated by fracture permeability associated with faults and folds.
With the exceptions of the Tertiary and alluvial aquifers, the rocks
comprising the sedimentary section have small interstitial permeabilities.
III. Water qualities vary widely within and between the various
saturated units. In general, ground waters with total dissolved
solids less than 500 mg/1 are encountered in outcrops of the Casper-
Tensleep, Sundance, Cloverly, Frontier, and Mesaverde aquifers along
2
-------
the flanks of the Laramie, Shirley, Medicine Bow, and Freezeout
mountains because these areas are the principal recharge areas where
residence times for ground water are relatively short and flow rates
are great. Water qualities in the various aquifers deteriorate basin-
ward as residence times increase and flow rates decrease. As the
water flows basinward, soluble sands dissolve from the aquifer matrices
and adjacent confining layers, and there is entrainment of poor quality
waters leaking from adjacent units. In general, total dissolved
solids increase as ground-water flow length increases.
Ground waters with total dissolved solids less than 500 mg/1
can be expected in much of the Tertiary aquifer in the Shirley basin
and Saratoga Valley because the rocks comprising the Tertiary aquifers
have large interstitial permeabilities and flow rates are great.
However, in the Hanna basin water qualities in the Tertiary aquifer
are variable with total dissolved solids ranging between 100 and 9,000
mg/1.
Total dissolved solids in local ground-water systems are generally
less than 500 mg/1.
IV. Insufficient data exist to allow thorough evaluation for
all U.S. Environmental Protection Agency primary drinking water
standards in the various aquifers; however, based on available chemical
analyses selenium and fluoride are identified in relatively large
concentrations in localized areas. For example, selenium concentrations
exceeding 0.01 mg/1 are encountered in ground waters in the (1) Frontier
Formation, 8 miles west of Laramie, Wyoming, along the Laramie River;
(2) Lewis Shale, 10 miles south of Walcott, Wyoming; and (3) Ferris-
Hanna formations undivided, 15 miles northwest of Hanna, Wyoming.
3
-------
Fluoride concentrations exceeding 2.0 mg/1 are encountered in ground
waters in the (1) Cloverly and Casper-Tensleep formations west and
north of Laramie, Wyoming; and (2) Ferris-Hanna formations undivided,
15 miles northwest of Hanna, Wyoming.
U.S. Environmental Protection Agency secondary drinking water
standards are exceeded in localized parts of all aquifers in the area.
In general, ground waters in the central parts of the various basins
exceed secondary standards for sulfate (250 mg/1), chloride (250 mg/1),
and total dissolved solids (500 mg/1).
V. Estimated total water use in the Laramie, Shirley, and
Hanna basins is about 2.0 x 10^ acre-feet/year. This total is based
on estimated domestic, industrial, and agricultural withdrawals.
About 40 percent or 8.0 x 10^ acre-feet/year of the total water demand
in the area is supplied by ground water.
Based on available data total domestic water use is about 3.8 x
t
4 4
10 acre-feet/year, of which about 3.0 x 10 acre-feet/year is supplied
by ground water. Principal ground-water sources for domestic use
include the Casper-Tensleep and Tertiary aquifers. Total industrial
water use is about 2.1 x 10^ acre-feet/year, of which about 99 percent
is supplied by ground water. Total agricultural water use is about
1.4 x 10^ acre-feet/year, about 20 percent of which is supplied by
ground water. Ground-water sources for agricultural use include
saturated alluvium, and the Tertiary, Casper-Tensleep, and Cloverly
aquifers.

11• INTRODUCTION
Synthesized herein are the hydrogeologic properties of the sedi-
mentary rocks, characterization of ground waters, and delineation
of potentially developable ground-water supplies in the Laramie,
Shirley, and Hanna basins, Wyoming. Interpretations and conclusions
in this report are based on the author's assessment of existing hydro-
geologic and structural data. No field work was undertaken during
the course of this study. This report is the third in a series of
seven ground-water investigations conducted by Wyoming Water Resources
Research Institute summarizing known conditions in the ten structural
basins of Wyoming.
Funding for this report was provided by the U.S. Environmental
Protection Agency through Contract G-008269-79, for the Underground
Injection Control Program (UIC). The UIC program is authorized by
the Safe Drinking Water Act (P.L. 93-523) and is designed to assure
the protection of ground-water resources from contamination as a
result of the injection of brines, sewage, and other hazardous fluids.
GENERAL
Purpose
The purpose of this report is to (1) describe the occurrence,
circulation, and chemical quality of ground water in the Laramie,
Shirley, and Hanna basins, Wyoming, and (2) quantify ground-water
use by aquifer and economic sector.

-------
Location
The location of the study area is shown on Figure II-1- The
area is entirely contained within the region between latitudes 41°00'
and 42°40', and longitudes 105°30' and 107°15'. The study area
encompasses approximately 9,300 square miles of State, Federal, and
privately owned lands situated primarily in Albany and Carbon counties,
Wyoming. All discussions in this report refer to the area within
these boundaries unless otherwise stated.
Physiographic Setting
The Laramie, Shirley, and Hanna basins are intermontane structural
basins. The locations of these basins relative to other intermontane
structural basins in Wyoming are shown on Figure II-2.
The eastern boundary of the study area is the north trending
Laramie range. The Laramie range spearates the area from the Denver-
Julesburg basin to the southeast and the Powder River basin to the north-
east. The southern boundary of the area is arbitrarily placed at the
Wyoming-Colorado state line. The western boundary includes the Sierra
Madre range and the Rawlins Uplift which separates the area from the
Washakie and Red Desert basins.
Elevations in the area generally range between 6,500 and 7,500
feet; however, elevations greater than 10,500 feet are not uncommon
in the various bounding mountain ranges.
Surface Drainage
The Laramie, Shirley, and Hanna basins are situated in the Missouri
River drainage system, North Platte River basin. As shown on Figure
II-l, principal streams include the Laramie, Little Laramie, North
Platte, Encampment, Medicine Bow, and Little Medicine Bow rivers.

The North Platte River basin is formally divided into six drainage
divisions (U.S. Department of the Interior, 1957), three of which
are included in the study area. Table II-l summarizes the various
divisions. Readers should refer to U.S. Department of Agriculture
and others (1979), Wyoming State Engineer (1973), and U.S. Department
of the Interior (1957) for detailed descriptions of the surface drainage
basins.
Climate
The climate of the Laramie, Shirley, and Hanna basins is semi-
arid continental, and is typified by extreme variations in temperature
and precipitation. Elevation is the principal control on local climatic
conditions.
Annual precipitation in the central part of the Laramie, Shirley,
and Hanna basins is generally less than 10 inches, whereas 12 to
16 inches is common along the elevated flanks of the basins. Fifty
inches of precipitation is common on the various bounding mountain
ranges (U.S. Weather Bureau, 1978).
The weighted annual temperature in the area is 42.3°F for the
period 1970 to 1978. Mean monthly temperatures range from 21°F
in January to 64°F in July, although recorded extreme temperatures
for the same period are -50°F and 97°F (U.S. Weather Bureau, 1978).
Population
Much of the Laramie, Shirley, and Hanna basins is sparsely popu-
lated. According to the U.S. Census (1970) about 40,000 people or
approximately 4 persons per square mile resided in the area in 1970.
The 1980 U.S. Census indicates that about 56,000 people or 6 persons

per square mile now reside in the area. Population distribution
is summarized on Table II-2.
Principal municipalities in the area include Laramie, Hanna,
Saratoga, and Medicine Bow, and account for about 60 percent of the
total population. About 23,000 people, representing 40 percent of
the total population, reside in rural areas or towns with fewer than
1,000 people.
Major industries in the area include agriculture, energy produc-
tion, and railroads. These industries employ about 75 percent of
the employable population in the area.
Land Use and Ownership
Agricultural activities account for about 60 percent of the
land use in the Laramie, Shirley, and Hanna basins. Although most
of the agricultural land is unimproved range, about 6 percent of
this land is utilized as cropland.
Mining and petroleum operations, homesteads, and recreational
areas occupy nearly all of the nonagricultural land.
About 49 percent of the land in the area is privately owned.
Federally owned lands, primarily administered by the Bureau of Land
Management and National Forest Service, account for about 44 percent
of the area. State owned lands account for the remaining 7 percent
of the study area.

Descriptions of the rocks appear in Table IV-2. Stratigraphic nomencla-
ture used here conforms to Littleton (1950) and Love and others (1955).
See their works for citations of original sources. The reader is
also referred to Blackstone (1953), Lowry and others (1973), Harshman
(1968), and Izett (1975) for useful summaries of sedimentation rates,
diagenesis, and sedimentary tectonics associated with the Laramie,
Shirley, and Hanna basins.
Structure
The Laramie basin is a broad north-south trending intermontane
structural depression that contains 12,000 feet of Cenozoic, Mesozoic,
and Paleozoic sediments which rest unconformably on Precambrian
crystalline rocks. The structure of the basin is complicated by
a series of east-northeast trending basement controlled shear zones
and several southwest plunging anticlines. The east flank of the
basin is characterized by low amplitude anticlines and synclines
as well as steeply, dipping monoclines which strike generally north-
south. The west flank of the basin is characterized by a segmented
overthrust zone.
The Shirley basin is a relatively small northwest trending inter-
montane structural depression that contains 8,000 feet of Paleozoic
and Mesozoic rocks which are unconformably overlain by Cenozoic rocks.
The structure of the basin is relatively uncomplicated. Except for
the west side of the basin, faults and folds are relatively sparse.
The Hanna basin is one of the deepest intermontane structural
depressions in the Rocky Mountain region, and yet it is one of the
smallest in areal extent. The basin is east-west trending, approxi-
mately' 40 miles long and 25 miles wide, and contains 30,000 to 35,000
17
-------
feet of Paleozoic, Mesozoic, and Cenozoic sediments which rest uncon-
formably on Precambriari crystalline rocks. The basin is informally
divided into two sub-basins: respectively, the Walcott and Carbon
basins (Dobbin and others, 1929). These are separated from each
other by the northeast trending Saddle Back Hills anticline, with
the Walcott basin lying to the north and the Carbon basin lying to
the south. The structure of the central part of the Hanna basin
is relatively uncomplicated with scattered low amplitude folds and
minor normal faults; however, along the periphery of the basin the
structure is complex with tightly folded, overturned, and highly
faulted sediments.
For an excellent summary of the late Cretaceous and Cenozoic
tectonic history of the study area the reader is referred to
Blackstone (1975).
Hydrostratigraphy
The stratigraphic position of springs and water encountered
in petroleum tests and water wells provides the best indicator of
saturated and permeable zones within the sedimentary rocks in the
area. Likewise, the uniform absence of springs and water encountered
in petroleum and water test wells in other parts of the sedimentary
section indicates that those units have negligible permeabilities
and are confining layers. Based on this premise an intensive litera-
ture search of available drill data, water encountered reports, ground-
water investigations, spring location maps, hydrologic atlases, and
appropriate stratigraphic and structural data was conducted to identify
water-bearing and confining layers.
18
-------
It is critical for the reader to understand that aquifers are
not dependent on formational boundaries. Rather, they are dependent
on permeability characteristics. As a result, an aquifer as used
in this report "...is a formation, group of formations, or part of
a formation that contains sufficient saturated permeable material
to yield significant quantities of water to wells and springs" (Lohman
and others, 1972, p. 2). This definition is rather vague because
the word "sufficient" must be defined by the user.
A confining layer as used here is a formation, group of formations,
or part of a formation that has a significantly lower ability to
transmit water than the aquifers that it separates. Although confining
layers have small permeabilities they are not impermeable. In fact,
given sufficient area and time a confining layer is usually capable
of leaking large quantities of water to adjacent units. To be sure
this distinction is not lost, confining layers are herein referred
to as leaky confining layers.
In addition to local deposits of saturated alluvium, six aquifers
were identified by this report. The aquifers are herein referred
to as the (1) Tertiary, (2) Mesaverde, (3) Frontier, (4) Cloverly,
(5) Sundance, and (6) Casper-Tensleep aquifers. The stratigraphic
positions of the various aquifers and leaky confining layers are
shown on Figure II-6. Detailed descriptions of the various aquifers
appear in Section IV.
As shown on Figure II-6, the various aquifers are identified
as (1) principal, and (2) secondary aquifers. Principal aquifers
are highly productive, and areally extensive. Principal aquifers
are reliable ground-water sources and have excellent development

III. WATER USE
-------
III. WATER USE
Both ground and surface water are used in the Laramie, Shirley,
and Hanna basins for domestic, industrial, and agricultural purposes.
Based on population estimates it is anticipated that domestic water
demand will increase by more than 50 percent by the year 2000 (Wyoming
State Engineer, 1973). Based on estimated water consumption for
various industries (Table III-l) industrial water demand will increase
by about 5 percent for the same period.
Surface water provides much of the water consumed in the Laramie,
Shirley, and Hanna basins. However, most surface water is geographically
confined to major drainage areas, and withdrawals are restricted
by interstate compacts. Conversely, ground water exists throughout
the area but extensive development is restricted by: (1) inadequate
delineation of developable aquifers, (2) drilling and production
costs, and (3) water development policies that emphasize utilization
of surface waters.
Estimated total water use in the Laramie, Shirley, and Hanna
basins is about 2.0 x 10^ acre-feet/year. This total is based on
estimated domestic, industrial, and agricultural withdrawals (Wyoming
State Engineer, 1973 and various; U.S. Environmental Protection Agency,
1980; U.S. Department of Agriculture and others, 1979; Wyoming Crop
and Livestock Reporting Service, 1979; Wyoming Oil and Gas Conservation
Commission, various; U.S. Department of the Interior, Bureau of Reclama-
tion, 1957).. At least 40 percent or 8.0 x 10^ acre-feet/year of the to-
tal water demand of the area is supplied by ground water. Total water

DOMESTIC WATER USE
Domestic water supplies are divided into public and private systems.
Public systems are subdivided into community and noncommunity systems.
For the purposes of this report a community system serves 25 or more
permanent residents. A noncommunity system serves less than 25 permanent
residents, but may serve a transient population of 25 or more. Non-
community systems include restaurants, hotels, bars, schools, and
campgrounds.
There are a total of 31 community (Appendix B) and 152 noncommunity
(Appendix C) systems in the area. Sources of water used by the various
community and noncommunity systems, respectively, are compiled in
Tables B-l and C-l.
A summary of water use by domestic sector and source of water
is compiled on Table III-2. Based on data presented in Table III-2
alluvium supplies the greatest quantity of ground water for domestic
use. The second greatest source of ground water for domestic use
is the Casper Formation.
Based on data presented in Table B-l, total water use for community
public water supply systems is about 1.1 x 10^ acre-feet/year. Ground-
3
water sources supply about 7.1 x 10 acre-feet/year, whereas surface
3
water sources supply about 3.6 x 10 acre-feet/year.
4
Total water use for noncommunity systems is about 1.9 x 10
acre-feet/year (Table C-l). All noncommunity systems reported in
Table C-l are supplied by ground-water sources.

aSources of data include Wyoming State Engineer (well permit files, 1980); U.S.
Environmental Protection Agency (1979). See Appendices B and C, respectively,
for specific community and noncommunity systems.
^Insufficient data exist to quantify water use by source. Sources ranked in
descending order according to the number of wells completed in the various
sources.
28
-------
The total number of permitted private domestic water supply
wells in the area is 2,131 (Wyoming State Engineer, 1980, water well
permit files). Permitted private domestic wells for which location
and water source are known are shown on Plate A-l. Insufficient
data exist to allow meaningful estimates of total water consumption
for permitted private domestic use. However, based on the population
estimate of about 20,000 rural residents and assuming that these
residents are supplied by permitted private domestic wells, and also
assuming an average per capita consumption of 180 gallons/day (Wyoming
State Engineer, 1973), private domestic ground-water use is at least
3
4 x 10 acre-feet/year.
INDUSTRIAL WATER USE
Principal industries using ground and surface water in the area
include coal, petroleum, uranium, cement, and timber companies. Esti-
mated water use for the various industries is compiled on Table III-l.
Based on data presented in Table III-l, total water use by the
4
various industries in the area is about 2.1 x 10 acre-feet/year.
About 97 percent or 2.0 x 10^ acre-feet/year is supplied by ground
water. Insufficient data exist to meaningfully quantify water use
by source; however, principal sources of ground water used by the
various industries include the Hanna, Ferris, Mesaverde, Cloverly,
and Casper formations.
Coal Industry
As indicated on Table III-l, the coal industry is the major
industrial user of water in the study area. According to Glass (1980)
water requirements for coal mines in the Laramie, Shirley, and Hanna
29
-------
basins range between 1,000 and 2,000 acre-feet/year per mine. There
are seven operating coal mines in the area.
The Tertiary and Mesaverde aquifers are principal sources of
water produced at the various coal mines. Specifically, saturated
units include the Hanna, Ferris, Medicine Bow, and Mesaverde forma-
tions. In addition, some saturated coal horizons are used.
Ground water is typically produced as a result of pit and shaft
dewatering. Uses for the water include: (1) dust suppression, (2)
processing and milling, and (3) domestic purposes.
Petroleum Industry
Estimated ground-water -withdrawals for the oil and gas industry
is listed in Table III-l. Ground-water withdrawals by the industry
are generally the result of by-product water from oil production
and water developed for secondary water-flood recovery projects.
According to Collentine and others (1981) the principal use for ground
water produced at the various oil and gas fields in the area is for
secondary recovery purposes.
As indicated in Table III-l, ground-water use by the oil and
3
gas industry has declined from 2.1 x 10 acre-feet/year in 1970,
3
to 1.7 x 10 acre-feet/year in 1980, and will continue to decline
because the various petroleum reservoirs in the area are becoming
depleted.
Ground water used by the oil and gas industry is usually produced
at the stratigraphic horizon of the petroleum reservoir. For example,
in the Laramie basin principal ground-water sources developed by
the industry include the Shannon, Muddy, Dakota, and Lakota sandstones,
whereas in the Hanna and Shirley basins principal sources include
30
-------
the Mesaverde, Morrison, Sundance, and Casper-Tensleep formations.
Insufficient data exist to allow meaningful estimates of yearly consump-
tive ground-water use by the oil and gas industry for the Laramie,
Shirley, and Hanna basins. However, the reader is referred to Collentine
and others (1981) for historic summaries of cumulative water-flood
rates and recovery projects for individual petroleum fields in the
area.
Uranium Industry
All active uranium mines in the area are located in Shirley
basin. Estimated ground-water withdrawal for the industry is listed
on Table III-l. Sources for ground water used by the uranium industry
include the Wind River and White River formations. The water is
principally used for dust suppression and processing operations.
Cement Industry
Estimated water consumption for the cement industry is listed
in Table III-l. About 60 percent of the water used by the industry
is from developed ground-water sources. According to 1980 estimates
2
this is about 1.2 x 10 acre-feet/year. Principal ground-water sources
developed by the cement industry include saturated alluvium along
the Laramie River, and the Casper-Tensleep aquifer south of Laramie,
Wyoming. About 40 percent or 8.0 x lO"*" acre-feet/year of surface
water is used by the industry. The Laramie River is the primary
source of surface water.
Timber Industry
According to 1980 estimates (Table III-l) the timber industry
uses about 50 acre-feet/year of water, of which about 50 percent
31
-------
is from developed ground-water sources. Ground-water sources developed
by the timber industry include highly fractured and jointed Precambrian
granite and saturated gruss. Surface-water sources used by the industry
include Fox and Douglas creeks, and various snowmelt catchments. The
water is primarily used for lumber processing, fire control, and
domestic purposes.
AGRICULTURAL WATER USE
Livestock
Water consumption by livestock in the Laramie, Shirley, and Hanna
basins is estimated at 2,100 acre-feet/year (Wyoming Crop and Live-
stock Reporting Service, 1979). Estimated water consumption arranged
by county for the various livestock populations are listed in Table III-3.
Principal sources of water for livestock use include the Tertiary
and Cloverly aquifers, and surface water from the various rivers,
creeks, and impoundments in the area. Insufficient data exist to
quantify water use by aquifer and surface-water source.
Irrigation
About 284,000 acres of land are permitted for irrigation in the
area. Annual consumptive use of ground and surface water for irrigation
is about 1.4 x 10^ acre-feet/year (Wyoming State Engineer, 1973; U.S.
Department of Agriculture and others, 1979). According to the Wyoming
Crop and Livestock Reporting Service (1979) about 20 percent of the
total irrigated acres in the study area are wholly or partially irri-
gated with ground water. According to the Wyoming State Engineer (1973)
annual consumptive use of ground water for irrigation is about 2.7 x
4
10 acre-feet/year. However, these estimates do not include system

losses and return flow of irrigation systems; total irrigation water
use may be 20 to 50 percent larger.
Principal sources of ground water for Irrigation are: (1) the
Casper aquifer along the eastern boundary of the study area, (2) the
Tertiary aquifer in the Hanna and Shirley basins, (3) the Mesaverde
aquifer near Rock River and Medicine Bow, and (4) saturated alluvium and
terrace deposits along the Laramie, Little Laramie, Encampment, and
North Platte rivers.
Ground-water development for irrigation purposes will be relatively
small in the immediate future. According to the U.S. Department of
Agriculture and others (1979) total irrigated acreage will increase less
than 5 percent by the year 2000. It is anticipated that surface water
will meet all additional irrigation requirements (U.S. Department of
Agriculture and others, 1979; Wyoming State Engineer, 1973). For
details of present and future irrigation programs including water use,
irrigated acreage, and management policies, the reader is referred to
U.S. Department of Agriculture and others (1979); Wyoming State
Engineer (1973); and Wyoming Crop and Livestock Reporting Service (1979).

IV. AQUIFERS
Six aquifers were identified by this report in the Laramie,
Shirley, and Hanna basins of Wyoming. These are the (1) Tertiary,
(2) Mesaverde, (3) Frontier, (4) Cloverly, (5) Sundance, and (6)
Casper-Tensleep aquifers. The various aquifers were identified on
the basis of water encountered reports for petroleum tests, completion
intervals for water wells, and spring locations. Water encountered
reports for petroleum tests are compiled on Table IV-].
In addition to the six aquifers, five regionally-continuous
leaky confining layers were identified by this report. The leaky
confining layers are comprised of the (1) Lewis Shale, (2) Steele,
Niobrara, and Sage Breaks shales, (3) Mowry and Thermopolis shales,
(4) Morrison Formation, and (5) Ghugwater and Goose Egg formations.
The reader is referred to Figure II-6 for the stratigraphic
position of the aquifers and leaky confining layers. A summary of
the ages, thicknesses, lithologies, and hydrologic properties of
the rocks exposed in the Laramie, Shirley, and Hanna basins appears
on Table IV-2.
PRINCIPAL AQUIFERS
Principal aquifers as used here include geologic environments
that contain sufficient permeable and saturated rocks to be attractive
for ground-water development. The various aquifers are generally
highly productive and areally extensive. Principal aquifers are
the (1) Tertiary, (2) Cloverly, and (3) Casper-Tensleep aquifers.

Tertiary Aquifer
The Tertiary aquifer is comprised of the North Park, Browns
Park, White River, Wind River, Hanna, Ferris, and Medicine Bow forma-
tions. Table IV-2 shows the thicknesses of the various units. The
aquifer is a complex sequence of discontinuous, lenticular, fine-
to-coarse-grain sandstone, fine-to-coarse-pebble conglomerate, coal,
siltstone,and shale with interbedded calcareous and organic shale,
friable dirty sandstone,and tuff. The interstitial permeability
of the aquifer is the greatest of any of the lithologic units in
the area. Permeabilities range between 20 and 2,050 gallons/day-
2
foot based on data presented in Table IV-3.
Much of the Tertiary section is elevated and dissected in the
study area, and in such locations the aquifer is unconfined. In
the central part of the Hanna and Shirley basins and in Saratoga
Valley the aquifer is structurally depressed and laterally continuous,
and in these areas the aquifer is semi-confined. Recharge to the
aquifer is largely by direct infiltration of precipitation into Tertiary
outcrops. Additional recharge occurs from stream losses into Tertiary
outcrops and by vertical leakage from underlying strata. Most recharge
to the Tertiary aquifer occurs between March and August when monthly
precipitation is greatest. Insufficient data exist to allow meaningful
recharge estimates for the Tertiary aquifer.
Springs discharge from the Tertiary aquifer in the northern
Laramie basin and throughout the Hanna and Shirley basins (Dana,
1962; Littleton, 1950; Saulnier, 1968; Visher, 1952). Most of the
springs discharge between 1 and 10 gallons/minute; however, selected
springs discharge 25 to 50 gallons/minute during peak recharge seasons.

One particularly important spring that discharges from the Tertiary
aquifer is Lake Creek spring, situated in T. 18 N., R. 83 W., Sec. 30.
According to Visher (1952, p. 8) the spring "...is probably fault
controlled" and discharged an estimated 1,300 gallons/minute from
the North Park Formation during August 1978 (Wyoming State Engineer,
various). The spring is developed by the Wyoming Game and Fish Depart-
ment and supplies water needs for the Saratoga Fish Hatchery.
The Tertiary aquifer is partially comprised of coal. Coal is
particularly important to this study because numerous coal seams
and subsidiary clinker deposits comprise some of the most productive
subaquifers within the Tertiary aquifer. For example, based on data
presented in Table IV-3 , permeabilities in coal/clinker deposits
2
range between 410 and 2,050 gallons/day-foot , whereas yields for
selected wells range between 4 and 100 gallons/minute.
Cloverly Aquifer
The Cloverly aquifer underlies the central parts of the Laramie,
Shirley, and Hanna basins, and includes the Cretaceous Cloverly Formation.
The Cloverly Formation is comprised of three members which are, in
ascending order, the (1) Lakota, (2) Fuson Shale, and (3) Dakota
(Table IV-2). These rocks are 50 to 200 feet thick in the area.
Outcrops of the unit are shown on Plate C-2. Water in the aquifer
is under confined conditions throughout the study area as evidenced
by artesian flows of 1 to 150 gallons/minute at the well heads of
selected petroleum tests (wells 1, 3, 4, 43, 45, 47) (Table IV-l).
The Cloverly aquifer is comprised of two permeable zones , the
Lakota and Dakota members, which are separated by the Fuson Shale
leaky confining layer. The presence of the Fuson Shale creates
60
-------
two confined subaquifers within the Cloverly aquifer that are hydrau-
lically connected by faults and fractures.
The most productive horizon in the Cloverly Formation is the
Lakota member. Based on hydrologic data presented in Tables 1V-3
and IV-4, permeabilities in the Lakota member range between 1 and
2
15 gallons/day-foot , and transmissivities range between 5 and 1,500
gallons/day-foot. Permeabilities in the Dakota member generally
2 ....
range between 0.3 and 2 gallons/day-foot , whereas transmissivxties
range between 10 and 20 gallons/day-foot.
Based on core samples from the Cloverly Formation a good qualitative
estimate of primary permeability and porosity is "good to very good"
(Core Lab, various; Halliburton Services, Inc., various; Wyoming
Geological Association, 1957). The fact that this unit is not generally
artificially fractured or stimulated in petroleum fields in the area
attests to the good permeability-porosity rating.
Recharge to the Cloverly aquifer occurs largely by (1) direct
infiltration of precipitation into Cloverly outcrops, and (2) leakage
from adjacent units. Insufficient data exist to allow meaningful
estimates of recharge to the aquifer.
The feasibility of developing ground-water supplies from the
Cloverly aquifer is good in the area. Although primary permeabilities
are good, the best prospects are situated along or near structurally
deformed areas where permeabilities are fracture enhanced.
Casper-Tensleep Aquifer
The Casper-Tensleep aquifer includes the Permian-Pennsylvanian
Casper Formation and the Pennsylvanian Tensleep Sandstone. The term
Casper-Tensleep is used here because the Casper Formation and Tensleep

-------
Sandstone are stratigraphically equivalent units in the area. In
general, the terms Casper Formation and Tensleep Sandstone are used
interchangeably in the Hanna and Shirley basins.
In the central and southern Laramie basin the Casper-Tensleep
aquifer is comprised of a series of permeable, medium-grain sandstones
and virtually impermeable interbedded limestones. These rocks are
600 to 800 feet thick. The presence of the limestone confining beds
creates a series of interbedded confined sandstone subaquifers within
the Casper-Tensleep aquifer that are hydraulically integrated into
one system by faults, joints, and subsidiary fractures (Boos, 1940
and 1941; Huntoon, 1976; Huntoon and Lundy, 1979).
In the northern Laramie, Shirley, and Hanna basins the Casper-
Tensleep aquifer is comprised of a series of permeable, fine-to-
medium-grain sandstones and impermeable shales interbedded with imper-
meable, finely-crystalline, dense limestone and dolomite. Based
on electric log correlations, the dolomitic zones grade laterally
into sandstone toward the north. According to Morgan and others
(1978) and Emmett and others (1972) visual inspection of core samples
for the Casper-Tensleep formation revealed extensive vertical fracturing
associated with the limestone and dolomite interbeds. The presence
of these fractures provides zones of large permeability.
The Casper-Tensleep aquifer underlies the entire study area.
The unit crops out along the flanks of the Laramie, Medicine Bow,
Shirley, and Freezeout mountains as shown on Plate C-l. Water in
the aquifer is under confined conditions throughout the area as evidenced
by artesian flows of 1 to more than 1,000 gallons/minute at the well
heads of various petroleum tests (Table IV-1) and water wells (Table
IV-3).
65
-------
The Casper-Tensleep aquifer is one of the most productive aquifers
in the study area; however, the ability of the unit to transmit water
is largely dependent on fracture permeability. For example, Lundy
(1978) found that hydraulic conductivities for relatively undeformed
parts of the aquifer ranged between 0.1 and 2.6 feet/day, whereas
in areas of enhanced fracture permeability the values ranged from
17 to 40 feet/day. Also, all major Casper-Tensleep springs are located
on or near faults and folds which attests to the hydraulic signifi-
cance of fracture permeability (Huntoon and Lundy, 1979).
Fracture permeabilities are critical for the hydraulic integration
of sandstone subaquifers in the Casper-Tensleep aquifer. This is
because the interbedded limestone and dolomite are highly competent
confining layers. For example, Huntoon and Lundy (1979) observed
that hydraulic conductivities in unfractured limestones are nil as
demonstrated by: (1) ponded water on moderately fractured limestone,
(2) no visible loss of water from ephemeral streams that flow over
limestone outcrops, and (3) head differences between limestone beds.
Sedimentary structures also provide zones of permeability in
the Casper-Tensleep aquifer. According to Emmett and others (1972)
and Morgan and others (1978) two dominant sedimentary structures
exist in the sandstones comprising the Casper-Tensleep formation
in the northern part of the area: these are (1) thin, homogeneous,
fine-grain , well-sorted sandstone zones of relatively large, uniform
porosity and permeability; and (2) highly cross-bedded zones, with
directional permeability parallel to the cross-bedding. The cross-
bedded zones are considerably less permeable. Examination of core
samples by Emmett and others (1972) and Morgan and others (1978)
66
-------
revealed that the homogeneous fine-grain sandstones had little
matrix cenent, whereas pore-filling material consisting of silica,
carbonate, anhydrite, and clay was common in the cross-bedded sand-
stones. It is reasonable to assume that the difference in matrix
cement significantly affects interstitial permeabilities.
Recharge to the Casper-Tensleep aquifer occurs primarily by
infiltration of precipitation directly into Permian and Pennsylvanian
outcrops. For example, Lundy (1978) observed a decrease in streamflow
across Casper Formation outcrops along an unnamed stream east of
Laramie, Wyoming. According to Lundy (1978) most recharge to the
Casper-Tensleep aquifer occurs between March and August when monthly
precipitation is above annual average. During fall and winter the
recharge is negligible because frozen ground conditions inhibit infil-
tration. Lundy (1978) estimates recharge to the Casper-Tensleep
aquifer in a 79 square mile area near Laramie to be 1.4 inches/year,
or about 10 percent of mean annual precipitation on the recharge
area.
Prospects for developing ground-water supplies in the Casper-
Tensleep aquifer are excellent. A summary of the hydrologic properties
of the unit are compiled on Tables IV-3 and IV-4. The unit is a pro-
ductive aquifer in highly fractured areas; however, yields diminish
as fracture permeabilities decrease.
SECONDARY AQUIFERS
Secondary aquifers as used here include geologic environments
that are permeable and saturated, but, for specific reasons that
are included in the individual discussions of the various aquifers,
are not as predictive as the principal aquifers.
67
-------
Mesaverde Aquifer
The Mesaverde aquifer is comprised of the Cretaceous Mesaverde
Formation. The Mesaverde Formation underlies the Hanna, the Shirley,
and the northwest part of the Laramie basins. The unit is largely com-
prised of alternating beds of fine-to-medium grain, cross-bedded sandstone,
carbonaceous shale, silty shale, and coal.
Much of the Mesaverde aquifer is elevated and dissected in the
northwest part of the Laramie basin, and in this area the aquifer
is discontinuous and unconfined. Springs that discharge from the
aquifer in this area generally drain elevated and highly dissected
outcrops. Recharge to these discontinuous systems occurs only from
direct infiltration of precipitation into the immediate outcrops.
In the Hanna and Shirley basins the Mesaverde aquifer is structur-
ally depressed and laterally continuous, and in these areas the aquifer
is semi-confined. Based on data presented in Tables IV-3 and IV-4,
permeabilities in the aquifer range from 0.5 to 210 gallons/day-
2
foot . According to Core Lab (various) interstitial permeabilities
in the unit are large. Recharge to the aquifer in the Hanna and
Shirley basins occurs largely by infiltration oE precipitation into
Mesaverde Formation outcrops and by leakage of water from adjacent
strata. According to the U.S. Geological Survey (various) recharge
also occurs from direct infiltration into sandstone bedrock in ephemeral
stream channels such as Foote Creek and the Medicine Bow River.
The most productive horizon in the Mesaverde aquifer is the
Pine Ridge Sandstone member. This horizon is 80 to 450 feet thick
and situated in the upper third of the Mesaverde Formation. The
Pine Ridge Sandstone is saturated in the Hanna and Shirley basins
68
-------
based on water encountered reports for petroleum tests, production
intervals in selected water wells, and spring locations. Wells
completed in the unit generally produce 1 to 50 gallons/minute, whereas
springs generally discharge 1 to 5 gallons/minute.
The Mesaverde aquifer is also highly productive in areas where
the unit is faulted and fractured. For example, geveral unnamed
fault-controlled springs discharge from the Mesaverde aquifer southwest
of Medicine Bow, Wyoming, in T. 22 N., R. 79 W., Sec. 10 and 16
(Wyoming State Engineer, various). The springs discharge 15 to 40
gallons/minute and are currently developed for stock use.
The feasibility of developing ground-water supplies from the
Mesaverde aquifer is poor in the northwest part of the Laramie basin
because the unit is elevated, dissected, and well-drained. Develop-
ment potential for the aquifer is good along the margins of the Hanna
and Shirley basins because the unit is saturated based on completion
intervals for water wells (Wyoming State Engineer, various) and spring
locations. Prospects for ground-water development are excellent
along the flanks of Elk Mountain where the Mesaverde aquifer is faulted
and fractured.
In general, the Mesaverde aquifer has not been developed for
municipal and community use because few towns are situated near
Mesaverde Formation outcrops. Towns underlain by the Mesaverde Forma-
tion generally do not utilize the aquifer because of the availability
of surface water and shallower sources of ground water.
Frontier Aquifer
The Frontier aquifer underlies much of the study area and includes
the Cretaceous Frontier Formation. The unit is 400 to 800 feet thick.
69
-------
The aquifer is comprised of a series of medium-grain, salt and pepper
sandstone, dark gray shale, with thinly laminated black shale and
sandy shale interbeds. Ground water in the Frontier aquifer is semi-
confined or artesian depending on the continuity of the confining
layers. For example, semi-confined systems exist in the southern
and central parts of the Laramie basin where confining shales are
elevated and dissected. Ground water is confined in the northwestern
part of the Laramie basin because the unit is buried and confining
layers are continuous.
Except for reported production rates for selected stock and
domestic wells, insufficient data exist to allow quantitative estimates
of aquifer parameters. However, the development potential for ground-
water supplies in the Frontier Formation is considered good, based on
a number of observations. These include: (1) primary perme-
abilities are good in upper Frontier sands (Stone, 1966); (2) upper
Frontier sands are saturated based on well yields of 10 to 25 gallons/
minute for selected stock wells in the study area; and (3) extensive
outcrops of the unit along the Laramie, Shirley, and Freezeout
mountains provide excellent areas for recharge.
Current development of ground-water supplies from the Frontier
aquifer is small because of the availability of shallower sources
of ground water and the availability of surface water in areas where
the rocks comprising the aquifer crop out.
Sundance Aquifer
The Sundance aquifer underlies much of the study area and includes
the Jurassic Sundance Formation. The Sundance Formation is comprised
of three massive, permeable sandstone members, which are easily
70
-------
distinguishable on electric logs. These are separated by virtually
impermeable shales and calcareous sandstones. The Sundance Formation
is 25 to 290 feet thick in the study area. The presence of the
impermeable shales and calcareous sandstones create three confined
subaquifers that are hydraulically integrated into one aquifer by
faults and fractures. According to Littleton (1950) only the middle
and basal sandstone units are water-bearing; however, it is the finding
of this report that all three units are saturated.
Permeabilities in the Sundance aquifer range between 1 and 10
2
gallons/day-foot (Table IV-A); porosity averages 18 percent.
According to Core Lab (various) and Halliburton Services, Inc. (various),
Sundance sands are relatively "tight," indicating small interstitial
permeabilities. Data presented on Table IV-A is for petroleum tests
situated in structurally deformed areas where permeabilities are
fracture enhanced.
The Sundance Formation crops out in limited exposures generally
in the east and northeast part of the study area as shown on Plate
C-3. Numerous springs and seeps discharge from the Sundance Formation
along the southwest flank of the Laramie mountains and north flank
of the Shirley and Freezeout mountains. Discharges from the various
springs are generally less than 1 gallon/minute (Wyoming State Engineer,
various). The relatively small discharges indicate that the rocks
have negligible permeabilities because available recharge to the
rocks in those elevated areas is relatively large.
Recharge to the Sundance aquifer occurs largely by leakage of
water from adjacent units. Recharge by direct infiltration of precipi-
tation is small because outcrops of the Sundance Formation are areally
limited, and permeabilities are small.
71
-------
LOCAL GROUND-WATER SYSTEMS
Local ground-water systems, as used here, are generally discon-
tinuous unconfined systems which supply water to wells and springs
along elevated and highly dissected outcrops. However, local ground-
water systems also include saturated alluvium and stray sands. Recharge
to local ground water systems occurs largely by direct infiltration
of precipitation into immediate outcrops. Recharge to saturated
alluvium occurs largely by stream loss.
Local ground-water systems supply numerous springs that discharge
from upper Cretaceous and Tertiary outcrops in the northwest part
of the Laramie basin, Saratoga Valley, and along the flanks of the
Shirley and Freezeout mountains. Typically, the springs are localized
along joints or at the base of permeable laminae perched above confining
beds.
Local ground-water systems supply numerous stock wells in the
southwestern part of the Laramie and northern parts of the Hanna
and Shirley basins. Wells in the southwestern part of the Laramie
basin are generally completed in undivided Permian-Triassic rocks,
whereas wells in the northern parts of the Hanna and Shirley basins
are completed in Tertiary rocks. According to the Wyoming State
Engineer (various) production rates for the various wells are highly
variable, being dependent on seasonal recharge.
Stray Sands
Stray sands, as defined here, include saturated and permeable
channel sandstones and sandstone lenses that are stratigraphically
included in leaky confining layers. Although the term "stray sand"
has no hydrogeologic meaning, it is used here because it is commonly
72
-------
used by well drillers to describe relatively thin (less than 100
feet) and generally discontinuous saturated sandstone units.
For example, the Shannon Sandstone is a stray sand. The Shannon
Sandstone is a member of the Steele Shale, and although the Steele
Shale is a regional leaky confining layer, the Shannon Sandstone
is a reliable, but undeveloped, source of ground water. Based on
data presented in Tables IV-3 and IV-A, permeabilities in the
Shannon Sandstone range between 1 and 10 gallons/day-foot _ According
to Core Lab (various) primary permeabilities in the unit are large.
Ground water in the unit is under confined conditions as evidenced
by artesian flows of 1 to 25 gallons/minute at the well heads of
selected petroleum tests (wells 17, 22, 61, 73, 85, Table IV-1).
The Shannon Sandstone is 40 to 80 feet thick in the area.
Stray sands have also been encountered in selected petroleum
tests in the Niobrara, Mowry, Thermopolis, and Morrison formations.
With the exception of the Thermopolis Shale, stray sands in the various
units are highly localized and discontinuous. The ground water in
the various sands is unconfined. Based on data presented in Table
IV-1, reported production for wells penetrating stray sands is generally
less than 10 gallons/minute.
For the purposes of this report the Muddy Sandstone is considered
a stray sand in the Thermopolis Shale, although it is 25 to 80 feet
thick and a key marker bed throughout the study area. Ground water
in the Muddy Sandstone is under confined conditions as evidenced by
artesian flows of 1 to 100 gallons/minute in selected petroleum tests
(wells 82, 83, 84, 88, 102, 150, Table IV-1). Based on data presented
in Table IV-4, permeabilities in the unit are less than 1 gallon/day-
2
foot .
73
-------
Prospects for developing ground-water supplies in the various
stray sands in the study area are fair to good. However, with the
exception of the Shannon and Muddy sandstones, stray sands are highly
localized and thus there is no assurance that saturated, permeable
zones will be encountered at all test well sites in the study area.
Saturated Alluvium
Unconsolidated alluvium of Recent age underlies the floodplains
of the Laramie, Little Laramie, Encampment, North Platte, Rock Creek,
Medicine Bow, and Little Medicine rivers. The alluvium consists
mainly of thin to medium beds of clay, silt, sand, fine to coarse
gravels,and boulders, and is 1 to 60 feet thick. The alluvium in
the area has excellent potential as a productive aquifer because
of its large permeability and because in many places the entire thick-
ness is saturated.
Wells completed in saturated alluvium are common along the Laramie,
Little Laramie, and North Platte rivers as shown on Plate A-l. Based
on pump test data (Banner Associates, Inc., 1979) permeabilities
in the alluvium along the Laramie River in T. 14 N., R. 76 W., Sec.
2
31, are about 3,000 to 3,300 gallons/day-foot , whereas transmissivities
and storage coefficients are, respectively, 150,000 to 200,000
gallons/day-foot and 0.35 to 0.02.

V. TECTONIC STRUCTURES AND GROUND-
WATER CIRCULATION
The permeabilities of the rocks in the area are significantly
enhanced by fractures. Consequently, ground-water resource evaluation
in the area requires information on the type, distribution, and inten-
sity of fracturing associated with the various tectonic structures.
The regional structure of the area is summarized on Plate B-l
and Figure V-l. According to Blackstone (1980) compressional forces
that occurred during the Laramide orogeny are the major cause for
the tectonic fabric.
As shown on Figure V-l, numerous folds exist in the area. The
various folds are of a variety of scales. For example, anticlines
and associated synclines in the central and southern part of the
Laramie basin are low amplitude structures with dips that are generally
less than 15°, whereas in the northern and northwestern part of the
Laramie basin folds with dips greater than 60° are common. Other
prominent folds include monoclines. The monoclines overlie high-
angle reverse faults in the basement rocks and have as much as 600
feet of structural offset (Huntoon, 1976, 1979).
The area is not highly dissected by faults; however, faults
are not uncommon. Locations of selected major faults are shown on
Figure V-l and Plate B-l. Displacements along the various faults
range from several tens to several thousand feet.
HYDRAULIC IMPORTANCE OF STRUCTURES
Folds, faults, and associated fractures are hydraulically important
because they establish vertically and horizontally integrated zones

-------
of large permeability in the rocks in the area. Although fractures
associated with folds and faults are localized, their permeabilities
are several orders of magnitude larger than adjacent unfractured
rocks. As a result saturated rocks along various structures have
excellent ground-water development potential.
An excellent example of the hydraulic importance of fracture
permeability involves the Casper-Tensleep aquifer. Table V-l summarizes
the relationship between tectonic structures and hydrologic properties
in the aquifer. In the vicinity of Laramie, Wyoming, the Casper-
Tensleep aquifer is faulted and folded. Huntoon (1976) and Lundy
(1978) found that permeabilities in fractured and faulted zones near
Laramie were 100 times greater than those in unfractured zones.
Another example of fracture enhanced permeability in the Casper-
Tensleep aquifer involves the Lietz #1 well, better known as the
Pat McGuire well (Table IV-3, p. 59). According to McGuire (1980) the
well produces 3,900 gallons/minute with no appreciable drawdown, but is
capable of producing as much as 8,000 gallons/minute. It is completed
in a saturated cavern that has developed along the axis of a steeply
dipping and highly fractured monocline. The importance of fracture
permeability at the McGuire well is demonstrated by the fact that
wells drilled by the Aluminum Company of America (ALCOA) in relatively
unfractured, saturated rocks adjacent to the McGuire well generally
produce less than 5 gallons/minute (Wyoming State Engineer, various).
Joints are hydraulically important because they provide zones
of laterally and vertically interconnected secondary permeability.
The fact that numerous springs are joint controlled in the area sub-
stantiates the previous statement.

Joints are found throughout the sedimentary section but are
best observed in the Casper and Mesaverde formations. This is largely
because these units are brittle and joint planes exposed in outcrops
are enlarged through weathering. Joints are also observed in the
Goose Egg Formation and Chugwater Group; however, clays and shales
comprising these units usually seal the joints.
Fracture Controlled Springs
Nearly all major springs that discharge from the Casper-Tensleep,
Sundance, Frontier, Mesaverde, and Tertiary aquifers are located
on or near faults or steeply dipping folds. For example, City, Soldier,
and Simpson springs are fault controlled springs that discharge from
the Casper Formation. The springs have been developed by the City
of Laramie, Wyoming, and respectively yield 1.7, 1.6, and 0.3 million
gallons/day (Laramie City Water Department, 1980).
¦•Other excellent examples of fault controlled springs include
three unnamed springs located north of Saratoga, Wyoming, that discharge
from the North Park Formation (Visher, 1952). The springs are located
at T. 18 N., R. 83 W., Sec. 30; T. 19 N., R. 83 W., Sec. 10; T. 20 N.,
R. 84 W., Sec. 16, and respectively discharge 1,300, 500, and 100
gallons/minute (Visher, 1952; Wyoming State Engineer, various).
Springs associated with steeply dipping folds are generally
controlled by the intersection of vertical joints and partings between
bedding planes. For example, Ambler spring (22-77-4 da) is a joint
controlled spring that discharges from the Casper Formation along
the north flank of the Como Bluff anticline. Ambler spring is perennial
and developed for stock use.
80
-------
GROUND-WATER CIRCULATION
Ground water moves in response to hydraulic gradients. Hydraulic
gradients develop naturally and are inclined from areas of recharge
to points of discharge. In general, ground-water circulation is
independent of the dip of the host rocks.
Regional Ground-Water Circulation
Potentiometric data are insufficient to allow construction of
meaningful water level maps for the various permeable units in the
area. However, potentiometric indicators such as static water levels
encountered in petroleum tests and water wells,' and elevations of
springs indicate that regional ground-water flow in the Cloverly
Formation is generally basinward as shown on Figure V-2. With the
exception of the Tertiary aquifer, ground-water flow directions shown
on Figure V-2 can be used to approximate flow directions in the
various aquifers in the area because the aquifers have similar recharge-
discharge areas and structural controls. Ground-water flow in unconfined
and semi-confined parts of the Tertiary aquifer is generally toward
the major surface drainages in the area. As shown on Figure V-2,
the Laramie, Shirley, and Hanna basins are internally drained.
In order tq understand ground-water circulation in the Laramie,
Shirley, and Hanna basins, consider Figure V-3, which represents
a basin cross-section and shows ground-water flow directions and
potential surfaces. As shown on Figure V-3, ground-water flow direc-
tions are basinward and intersect potential surfaces (lines connecting
points of equal total head) at right angles. As the ground water
moves basinward there is a strong vertical flow component and as
a result there is upward leakage of water. Assuming that hydraulic

conductivities are constant, the spacing of the potential lines indi-
cates that ground-water flow in the deep basin center is relatively
small compared to the flow along the flanks of the basin. In other
words, the closer the spacing of the potential lines, the greater
the ground-water flow. This is very nearly the situation that exists
in the area today, because ground waters in the deep basin centers
generally have longer residence times than ground waters in outcrops
along the flanks of the basins.

VI. WATER QUALITY
-------
VI. WATER QUALITY
Water analyses for approximately 350 wells and springs were
evaluated to determine the quality and chemical character of the
ground water in the various aquifers in the area. The analyses were
selected to include: (1) a diversity of geographic sources for the
ground water, (2) a number of different stratigraphic and structural
settings for the wells and springs, and (3) most of the major springs
in the area.
The results of the chemical analyses are presented in Appendix D>
and the waters are classified by type based on the relative proportions
of major ions (Piper, 1944). The chemical analyses provide qualitative
insights into: (1) approximate source rocks for the ground water,
(2) evolution of ground-water chemical quality and therefore direction
of ground-water flow in the geologic section, and (3) relative residence
times of the ground water.
In general, ground waters with total dissolved solids less than
500 mg/1 are encountered in outcrops of the various saturated units
along the flanks of the Laramie, Shirley, Medicine Bow, and Freezeout
mountains. The flanks of the various mountains are principal recharge
areas where residence times for ground water are relatively short
and flow rates are great. Water qualities deteriorate basinward
mainly because o£ (1) long residence time, (2) small flow rates,
(3) dissolution of soluble salts from the aquifer matrix and from
adjacent confining layers, and (4) leakage of poor quality waters
from adjacent units. In general, total dissolved solids concentrations
increase as ground-water flow length increases.
86
-------
LOCAL AQUIFERS
Local aquifers discharge water in direct response to infiltration
of precipitation into immediate outcrops. Most ground water in local
aquifers is potable (total dissolved solids less than 500 mg/1) without
treatment because: (1) residence time for the water is relatively
short, and (2) flow rates are great.
Saturated Alluvium
Representative chemical analyses for ground water in alluvium
are listed in Table D-l. The samples are of the calcium-magnesium-
bicarbonate type. The quality of the water is influenced by con-
centration of dissolved solids through evaporation (U.S. Geological
Survey, 19 71; Freudenthal, 19 79).
In general, the chemical qualities of water in alluvial deposits
are very good. As indicated in Table D-l, total dissolved solids
are usually less than 500 mg/1.

Results of 192 analyses for ground waters in the Tertiary aquifer
are compiled in Table D-l. Representative analyses are plotted on
the trilinear diagram in Figure VI-1. Ground waters in the Ferris
and Hanna formations are of the sodium-magnesium-sulfate type and
are highest in total dissolved solids, whereas ground waters in the
North Park, Wind River, and White River formations are of the calcium-
bicarbonate type and are lowest in tota] dissolved solids.
In the Saratoga Valley the Tertiary aquifer is comprised of
the North Park and Browns Park formations. As shown on Plate C-l
total dissolved solids in the Tertiary aquifer are generally less

than 500 mg/1 in this area. In general, chemical qualities are very
good because the units comprising the aquifer in the Saratoga Valley
have large interstitial permeabilities and ground waters circulate
rapidly through the rocks. However, it should be noted that in the
central part of the Saratoga Valley there is an area where total
dissolved solids in selected spring samples range between 1,000 and
3,800 mg/1 (Plate C-l). The samples represent fault controlled geo-
thermal springs that discharge from Tertiary rocks, but the source
of the ground water is undetermined Paleozoic units (Breckenridge
and Hinckley, 1978).
In the Shirley and northern part'of the Laramie basins the Tertiary
aquifer is comprised of the White River and Wind River formations.
Ground waters in these units are, respectively, of the calcium-magnesium-
bicarbonate and calcium-bicarbonate type, as indicated in Table VI-1.
As shown on Plate C-l total dissolved solids in the aquifer in this
area are generally less than 500 mg/1. Permeabilities in the White
River and Wind River formations are large and as a result ground
waters circulate rapidly through the rocks.
In the Hanna basin the Tertiary aquifer is comprised of the
Hanna, Ferris, and Medicine Bow formations, and as shown on Plate
C-l total dissolved solids in this area range between 400 and 9,000
mg/1. As indicated in Table VI-] the Hanna and Medicine Bow formations
contain water that is of the sodium-magnesium-sulfate type. In general,
total dissolved solids increases are associated with increased concen-
trations of sodium, sulfate, and chloride.
The Tertiary aquifer is an excellent source for domestic ground
water in many parts of the area. However, the various sedimentary
89
-------
units comprising the aquifer are hosts for high-grade uranium roll-
front deposits (Stephens and Bergin, 1959; Harshman, 1968,
1972; Bailey, 1964). Typically, the uranium deposits are associated
with highly permeable, saturated channel sandstones. As a result
ground-water supplies in the Tertiary aquifer should be tested for
radionuclides.
MESAVERDE AQUIFER
Based on 11 chemical analyses plotted on the trilinear diagram
in Figure VI-2, ground waters in the Mesaverde aquifer are predomi-
nantly of the sodium bicarbonate or sodium sulfate type. The gross
chemical character of the water is controlled by dissolution of calcite,
dolomite, and gypsum from the aquifer matrix with cation exchange
of sodium for calcium and magnesium. The base exchanges are probably
controlled by interaction of ground water and local confining shale
interbeds. Total dissolved solids range between 181 and 4,970 mg/1;
however, 8 of the 11 samples contain total dissolved solids less
than 1,200 mg/1 (Table D-l).
Total dissolved solids concentrations increase basinward and
with drilling depths to the Mesaverde aquifer. Total dissolved solids
concentrations are less than 500 mg/1 in outcrops of the Mesaverde
Formation along the margins of the various basins, whereas total
dissolved solids concentrations greater than 1,000 mg/1 are common
in areas where the aquifer is buried. The increased total dissolved
solids are generally associated with increased sodium and sulfate
concentrations.

-------
FRONTIER AQUIFER
The results of seven chemical analyses (Table D~l) for Frontier
aquifer waters are plotted on the trilinear diagram in Figure VI-3.
Analyses of Frontier waters indicate a basinward change in gross
chemical character from sodium-bicarbonate waters at outcrop to sodium-
bicarbonate-sulfate waters where the aquifer is structurally depressed
and buried. Total dissolved solids concentrations also increase
basinward from less than 1,000 mg/1 at outcrop, to greater than 3,000
mg/1 in the central basin areas. Increased total dissolved solids
are generally associated with increased sulfate and chloride concen-
trations .
Three principal factors influence major ion water chemistries
in the Frontier aquifer: (1) lithology, (2) residence time for the
ground water, and (3) leakage of poor quality waters from adjacent
units. For example, the Frontier Formation is partly comprised of
shales and clays and as a result ground waters with long residence
times will dissolve soluble salts from the argillaceous rocks. Also,
based on the fact that heads increase with depth in the saturated
units in the area vertical leakage of poor quality waters is expected
from the underlying Mowry Shale. Ground waters in the Mowry Shale
are generally chloride rich.
STRAY SAND - MUDDY SANDSTONE
Based on the results of seven chemical analyses (Table D-l)
plotted on the trilinear diagram in Figure VI-4, ground waters in
the Muddy Sandstone are of the sodium-chloride type. Both sodium
and chloride concentrations are generally greater than 1,200 mg/1.
The gross chemical quality of Muddy Sandstone water is controlled

by lithology. According to Crawford (1940) shale and silt in the
aquifer matrix is the major source for sodium and chloride ions.
Total dissolved solids in the Muddy Sandstone range from 3,000
to more than 9,500 mg/1. Based on data presented in Table D-l and
Crawford (1940, pp. 1252-1255) total dissolved solids concentrations in
the Muddy Sandstone are relatively large in both outcrop and structurally
depressed parts of the basins.
Muddy Sandstone waters are distinguishable from waters in the
overlying Frontier Formation on the basis of chloride concentrations.
Frontier waters generally contain chloride concentrations lower than
500 mg/1.
CLOVERLY AQUIFER
The results of 45 chemical analyses for ground waters in the
Cloverly- aquifer are compiled in Table D-l. Representative samples
are plotted on the trilinear diagram in Figure VI-5. Ground waters in
the Cloverly aquifer are dominantly of the sodium-bicarbonate-chloride
type. According to Crawford (1940) the gross chemical character of
the ground water is principally controlled by the various lithologic
units comprising the aquifer and residence times.
Cloverly water is characterized by low total dissolved solids
and is sodium-bicarbonate rich in areas where the Cloverly Formation
crops out. This is largely because flow rates are great and residence
time is relatively short. Water qualities deteriorate basinward
and with depth to mixed anion waters with intermediate total dissolved
solids concentrations (1,000 to 5,000 mg/1), to sodium-chloride rich
waters with large total dissolved solids concentrations (greater than
5,000 mg/1).

96
-------
Based on data presented in Table D-l, water qualities improve
where the aquifer is faulted and highly fractured because the faults
and fractures increase permeabilities and as a result flow rates
are increased and residence time is shortened. For example, samples
22, 31, 32, 36, and 37 (Table D-l) represent Cloverly Formation waters
in faulted and folded parts of the aquifer. Total dissolved solids
in the respective samples are 200, 188, 607, 587, and 288 mg/1. By
comparison, samples 33, 34, and 38 (Table D-l) represent waters in
relatively unfractured areas adjacent to the locations of the previous
samples and total dissolved solids are, respectively, 24,100, 11,800,
and 2,000 mg/1. In all of the aforementioned examples drilling depths
to the Cloverly Formation exceeded 2,000 feet.
SUNDANCE AQUIFER
Based on the results of 20 chemical analyses (Table D-l) plotted
on the trilinear diagram in Figure VI-6, ground water in the Sundance
aquifer is of the sodium-bicarbonate type along the margins of the
various basins in the area. Basinward, the gross chemical character
of the water changes to mixed anion with increased sulfate and chloride
concentrations.
Total dissolved solids concentrations in the Sundance aquifer
are relatively uniform throughout the sampled area (Plate C-3). For
example, as indicated in Table.D-l, with the exception of samples
1, 42, and 43, total dissolved solids in 45 representative samples
range between 1,000 and 3,000 mg/1, with 56 percent of the samples
containing total dissolved solids between 1,000 and 2,000 mg/1. Samples
1, 42, and 43 are for fault controlled springs, whereas all other
samples are for petroleum test wells.

CASPER-TENSLEEP AQUIFER
Water analyses for the Casper-Tensleep aquifer are compiled
in Table D-l, and the results are plotted on the trilinear diagram
in Figure VI-7 . The gross chemical character of Casper-Tensleep
water is controlled by (a) dissolution of calcite and dolomite in
the aquifer matrix (Lundy, 1978), (b) residence time of the ground
water, and (c) flow rates. At outcrop, ground water is of the calcium-
bicarbonate type (samples 5, 7, 8, 9, 15, 17, 45, 52, Figure VI-7).
Total dissolved solids concentrations are usually less than 500 mg/1,
because residence time is short and flow rates are great. Basinward
the water becomes calcium-magnesium-bicarbonate rich and total dissolved
solids concentrations are generally between 1,000 and 1,500 mg/1 (samples
10, 30, 32, 36, 39, AO, 47, 48, 49, Figure VI-7). In the central
part of the various basins the aquifer is deeply buried and ground
water is of the sodium-sulfate and sodium-chloride type (samples
1, 33, 34, 45, 55, 57, 58, 59, 61, 62, Figure VI-7). Total dissolved
solids are generally greater than 8,000 mg/1. The poor water qualities
can be attributed to long residence times.
Casper-Tensleep waters are distinguishable from overlying Permian-
Triassic redbed waters on the basis of magnesium and sulfate concentra-
tions. According to Lundy (1978) Permian-Jurassic redbed waters
contain ten times as much sulfate as Casper-Tensleep waters. It
is the finding of this study that Permian-Triassic redbed waters
also contain at least five times as much magnesium as Casper-Tensleep
waters. In areas where the two units are hydraulically connected
by faults and fractures representative waters contain intermediate
concentrations of magnesium and sulfate.

PRIMARY DRINKING WATER STANDARDS
Primary drinking water standards established by the U.S. Environ-
mental Protection Agency (1976) are summarized in Table VI-1. Insuf-
ficient data exist to allow thorough evaluation for all primary con-
stituents in the various saturated rocks in the study area; however,
based on available chemical analyses, selenium and fluoride are identified
in relatively high concentrations in parts of the area. Figure VI-8 shows
(1) sample point locations, (2) source of ground water, (3) primary specie,
and (4) concentration in mg/1 for areas where primary standards are ex-
ceeded .
As shown on Figure VI-8, selenium concentrations exceeding standards
(0.01 mg/1) are encountered in ground waters in the Ferris, Lewis, and
Frontier formations. Concentrations range from 0.02 to 0.08 mg/1.
Concentrations of fluoride above the standard (2.0 mg/1) are en-
countered in ground waters in the Ferris, Cloverly, and Casper forma-
tions in localized areas (Figure VI-8). The fluoride concentrations
range between 2.5 and 7.3 mg/1.
Radionuclides
Sixteen water samples were collected from the various aquifers
in the area by the Wyoming Water Resources Research Institute and
analyzed for radionuclide concentrations. The radionuclide species
analyzed are gross alpha, gross beta, radium-226, and total dissolved
uranium (U^Og). It should be noted that the radionuclide analyses are
for ground waters at site specific areas and should not be applied as
indicators for ground waters throughout an entire aquifer or rock unit.
The U.S. Environmental Protection Agency has taken an admittedly

conservative approach that all radionuclide species are harmful, and
that a linear relationship exists between dosage and cancer occurrence
(U.S. Environmental Protection Agency, 1976). Primary drinking water
standards established for radium-226 and gross alpha are, respectively,
5 and 15 pCi/1 (Table VI-1). No standards have been established for
dissolved uranium and gross beta.
Reported concentrations of radium-226, gross alpha, and gross beta
contain an error limit that indicates a 95 percent confidence interval.
Error limits reported in Table E-l range from 0.1 to 11 pCi/1. The
larger error limits are due to (1) instrument insensitivity at low
concentrations and (2) particle absorption in samples containing high
dissolved solids.
Based on the analyses compiled in Table E-l, radium-226 concen-
trations do not exceed primary standards (Table VI-1) in any of the
sampled waters. The largest concentration of radium-226 was identi-
fied in Casper Formation water from the Town of Medicine Bow well, near
the Como Bluff anticline (4.k ±0.6 pCi/1, a concentration that is still
within primary standards).
Three of the 16 formation waters sampled contain gross alpha
concentrations that exceed primary standards. The three waters are
from the Casper, Tensleep, and Madison formations. The gross alpha
concentrations have a "potential" maximum range of 17 to 27 pCi/1.
According to Hem (1970), uranium-U^Og concentrations of up to
0.01 mg/1 are common in most ground waters; however, concentrations
greater than 0.01 mg/1 are unusual. Six of the 16 water samples
contain UgOg concentrations greater than 0.01 mg/1 (ranging from 0.019
to 0.065 mg/1). Reasonable explanations for the large concentrations
105
-------
include (1) the presence of uranium deposits in the host aquifer, (2)
migration of uranium from other formations under oxidizing conditions
or in the presence of carbonate ions (Collentine and others, 1981),
and (3) intermixing of uranium-rich waters from overlying rocks in the
well annulus: since well completion records do not exist for all of
the sampled wells, there is a possibility that a well may have been
open-hole completed.
SECONDARY DRINKING WATER STANDARDS
Secondary drinking water standards are summarized in Table VI-1.
Secondary standards of interest to this study include chloride, sulfate,
and total dissolved solids. Although these constituents are not con-
sidered toxic, they are thought to be undesirable in excessive quantities
in drinking water. In many areas, however, because no better drinking
water is available residents have adjusted to drinking highly mineralized
water.
Secondary drinking water standards are exceeded in selected water
analyses for all of the aquifers in the study area. The reader is re-
ferred to Table D-1 for specific chemical analyses, sources of ground
water, and sample locations. Plates C-l, C-2, C-3, and C-4 show the
areal distribution of total dissolved solids in the various aquifers
in the area.

APPENDIX A
WELL AND SPRING NUMBERING SYSTEM
-------
WELL AND SPRING NUMBERING SYSTEM
Water wells, oil and gas test wells, and springs cited in this
report are numbered according to the U.S. Geological Survey system
that specifies the location of the site based on the Federal land
subdivision system. An example is shown on Figure A-l.
In this example, 15-72-9 bed, 15 refers to the township, 72 to
the range, and 9 to the section in which the well is located. The lower-
case letters that follow the section number identify a smaller tract of
land within the section. The first letter (b in this example) denotes
a 160-acre tract, commonly called a quarter section. The second letter
(c) denotes a 40-acre tract, commonly called a quarter-quarter section.
The third letter (d) denotes a 10-acre tract or a quarter-quarter-quarter
section. The letters a, b, c, and d indicate respectively the northeast,
northwest, southwest, and southeast tracts of the respective subdivision.
