1.0 Executive Summary
Far West Texas contains three Texas Water Development Board (TWDB)-designated
major aquifers and six minor aquifers. In addition, there are a number of areas within the Region
that have no aquifer designation but in which groundwater is the primary source of supply. The
purpose of this project is the establishment of additional aquifer characterization data upon
which to base further groundwater availability analyses. The acquisition of additional aquifer
characterization data will benefit the Far West Texas Water Planning Group in better defining
available water supplies in the region, and will also support groundwater conservation districts in
their responsibility of managing supplies and evaluating future desired conditions.
New hydrologic data in the form of static water level and well yields is tabulated from
driller's reports on wells that have been drilled in recent years in Brewster, Culberson, Jeff Davis,
and Presidio Counties. Where possible, as in Jeff Davis and Presidio Counties, well
identification is coordinated between groundwater conservation district tracking numbers and
Texas Department of Licensing and Regulation tracking numbers. A limited number of new
wells and updated existing well data in eastern Hudspeth County was field measured and
observed.
Water samples were collected from 22 wells and springs using recognized standard
procedures and the samples were analyzed for basic inorganic constituents. All analyses indicate
excellent quality water with total dissolved solids ranging from 87 to 545 milligrams per liter
(mg/l). Four aquifer pumping tests were conducted during this project with transmissivities
ranging from 190 to 198,570 (gpd/ft) and an additional four pumping tests are included that have
been performed in the area but are not noted in the TWDB groundwater files.

2.0 Introduction
Far West Texas contains three TWDB-designated major aquifers and six minor aquifers.
In addition, there are a number of areas within the Region that have no aquifer designation but in
which groundwater is the primary source of supply. There is currently a deficiency of
hydrologic data on file to support groundwater supply availability analysis for much of the more
rural portions of both the designated and non-designated aquifer areas. Due to the overwhelming
reliance on groundwater, the Far West Texas Water Planning Group strongly feels that it is
imperative that aquifer availability analyses be significantly improved such that they can have
more confidence in strategy recommendations involving groundwater resources.
The purpose of this project is the establishment of an additional amount and distribution
of aquifer characterization data upon which to base further groundwater availability analyses.
The acquisition of additional aquifer characterization data will benefit the Far West Texas Water
Planning Group in better defining available water supplies in the region, and will also support
groundwater conservation districts in their responsibility of managing supplies and evaluating
future desired conditions.
The preliminary task in this project was to review the existing distribution of well data in
the TWDB groundwater database and determine areas that are deficient in well data coverage,
with emphasis in areas of current or future groundwater availability modeling efforts. In pursuing
this task, no additional data was identified in the Rustler Aquifer as only a small part of this
aquifer lies within this Region. Likewise, no additional data of significance was identified in the
West Texas Bolsons Aquifer that would result in improvements to the recently completed West
Texas Bolsons Aquifer Groundwater Availability Model.
While the interest of this data acquisition project centered on the rural counties of Far
West Texas, the desire to not overlap coexisting and impending projects allowed the focus to be
narrowed to more specific rural areas. TWDB staff were contemporaneously collecting field
data from wells completed in the Capitan Reef Aquifer in Culberson and Hudspeth Counties. By
verbal coordination with TWDB field staff, we did not attempt to gather data for this aquifer
other than recent driller's reports. We did offer to conduct pumping tests on Capitan Reef wells
if the TWDB staff identified appropriate wells to test; however, no wells were identified. The

County are slated for more detailed attention in 2009 during the next round of regional water
planning; therefore, these areas were not considered for pumping tests.
Based on the results of the preliminary task of identifying areas of well data distribution
needs, we recommended to the Planning Group that we concentrate our efforts on areas of
significant pumpage as these are the areas that are of the greatest importance in groundwater
modeling exercises. The Planning Group agreed and we proceeded to complete the data
acquisition and pumping tests. New water wells reported by water well drillers were surveyed,
positioned on maps, and data filed in tables in Brewster, Culberson, Jeff Davis, and Presidio
Counties. Aquifers that were covered in this survey included the Igneous, Edwards-Trinity
(Plateau), Capitan, Rustler, West Texas Bolsons, and other undocumented aquifers. Water
quality samples were collected and analyzed, and pumping test were performed on Igneous
Aquifer wells in Brewster, Jeff Davis, and Presidio Counties.
Activities involved in this project were coordinated with Sul Ross State University and
groundwater conservation district managers. Sul Ross State University is a member of the Texas
State University System, which is currently participating in the US Department of Agriculture's
"Sustainable Agricultural Water Conservation in the Rio Grande Basin" research project.
Specifically, Sul Ross staff participated in this project by assisting in the selection of pumping
test sites, providing measuring equipment, and assisting with the actual testing process in the
field. Groundwater conservation district managers in Brewster, Culberson, Jeff Davis and
Presidio Counties participated in the project by sharing well records and assisting with gaining
landowner permission to conduct pumping tests and collect water samples. The Jeff Davis
UWCD is the only district with data not on file with the state (see Table A.3).

3.0 Groundwater Data Acquisition
3.1 Well Data
A significant number of wells are currently documented in the TWDB groundwater
database (Figure 3.1). New hydrologic data not in the TWDB database in the form of static
water levels and well yields are tabulated from driller's reports on wells that have been drilled in
recent years in Brewster, Culberson, Jeff Davis, and Presidio Counties. Locations of these new
wells are shown in Figures 3.2 through 3.5 and tables listing the wells are provided in Appendix
A (Tables A.1 – A.5). Where possible, as in Jeff Davis and Presidio Counties, well identification
is coordinated between groundwater conservation district identification numbers and Texas
Department of Licensing and Regulation tracking numbers. It should be noted that these wells
have not been field surveyed and, therefore, latitude and longitude coordinates as provided by the
reporting driller may be subject to error. A limited number of new wells and updated well data in
eastern Hudspeth County was field measured and observed (Appendix A: Table A.5).
3.2 Water Quality
The TWDB maintains numerous water quality analyses in its groundwater database.
Figure 3.6 shows the distribution of wells from which these water quality analyses were derived.
For this project, water samples were collected from 22 wells and springs (Figure 3.7) using
recognized standard collection procedures. The samples were sent to a reputable laboratory to be
analyzed for basic inorganic constituents. A summary of these analyses is listed in Table 3.1.
All analyses indicate excellent quality water with total dissolved solids ranging from 87 to 545
mg/l.

4.0 Aquifer Pumping Tests
When a well is pumped and water is withdrawn from an aquifer, water levels in the
vicinity are drawn down to form an inverted cone with its apex located at the pumping well.
This is referred to as a cone of depression. Groundwater flows from higher water levels to lower
water levels and, therefore, in the case of a pumping well, toward the well or the center of the
cone of depression. The shape and size of the cone is directly related to the aquifer’s hydraulic
parameters. Pumping tests are the accepted standard for evaluating this cone of depression, and
thus determining an aquifer’s capacity to produce water.
Areas of specific interest in conducting pumping tests were those in which the aquifer
was undergoing the most pumping stress. Municipal well fields and irrigation projects were
most characteristic of this condition. The technical selection of wells to be tested was based on
the following requirements:
• A working pump in the pumping well.
• A method to discharge water away from the immediate vicinity of the well.
• A method of estimating the rate of discharge.
• An available entry port for access of measuring equipment.
• Agreement by the land/well owner to allow the continuous pumping to occur for a
designated minimum time period.
• Agreement by the land/well owner that test results would be made publically
available.
• And also important to the validity of the results of the test, that a separate
observation well be available in which to monitor water level change at a
specified distance from the pumping well.
As discussed in the Introduction section of this report, certain areas were not considered
for testing because of the desire to not overlap existing or impending project areas. Thus the
Capitan Reef, Marathon, and Edwards-Trinity (Terrell County) Aquifers were not considered for
this round of testing.
Figure 4.1 shows wells contained in TWDB and TCEQ databases that provide various
forms of well production characterization. In some cases the data may represent transmissivity
-

calculations from a complete pumping test, while others may contain simple well yield (gallons
per minute) estimates by the water well driller or well yield and total water-level drawdown
(specific capacity).
Figure 4.2 provides the location of wells in which current pumping tests were performed
for this project, along with the location of other pumping tests that are not available in the
TWDB groundwater database. Table 4.1 provides a list of wells used in both the current and
previous pumping tests. Results of these pumping tests are provided in Appendix B and C.
Individuals that provided significant assistance in performing the pumping tests include:
• Ms. Janet Adams - Manager of the Jeff Davis County and Presidio County
Underground Water Conservation Districts
• Dr. Kevin Urbanczyk - Sul Ross State University
• Ms. Cindy Hollander - Utility Department Manager, City of Alpine

5.0 Conclusions and Recommendations
The Texas Legislature, through the Texas Water Development Board, has designated 16
groundwater management areas (GMA), each of which incorporates all or significant portions of
the major and minor aquifer systems in the state. The rural counties of Far West Texas are
located within GMA 3, 4 and 7. Groundwater conservation districts (GCD) in each GMA are
charged with developing the "desired future conditions" (DFC) of their respective aquifers.
Based on these DFCs, the TWDB will develop "managed groundwater availability" (MGA)
volumes for each aquifer, which each GCD must use in their water management permitting
procedures. Regional Water Planning Groups will also be required to use these aquifer MGA
volumes when assessing water supply management strategies in future plans.
A key factor in establishing the preliminary DFCs and the ultimate MGAs is knowing
how much groundwater is being pumped from each aquifer and for what purpose. To estimate
this quantity, it is essential to know the number and use of wells in each county. At the present
time, the groundwater conservation districts in this Region are at different stages of developing
an inventory of all wells in their respective districts. Although the water well driller's data
included in this report is unconfirmed, it still provides a significant step forward in starting or
continuing groundwater conservation district water well inventories.
To support the goal of securing better hydrogeologic characterization of the numerous
aquifers in the Region, the Far West Texas Water Planning Group, with the assistance of the
Texas Water Development Board, has continued a program of basic water well data acquisition.
The goal of the current project was to produce information pertaining to: (1) the number and
location of new wells that have been drilled in the past 10 years; (2) additional water quality
analysis of samples of wells and springs that had not been previously sampled; and (3) pumping
tests of several, mostly high-capacity wells. This project produced water well drillers data on
more than 500 wells, water quality analyses from 22 wells and springs, and aquifer
characterization information determined from eight pumping test centers.
The next step in the Far West Texas program of aquifer characterization is currently
underway as pumping tests and well data inventories are being conducted in the Marathon
Aquifer in Brewster County and the Edwards-Trinity (Plateau) Aquifer in Terrell County.
