INTRODUCTION
The Upper Santa Cruz River Basin is one of the major river
drainages in Southern Arizona that has a component of flow
originating in Mexico. The water quality and quantity of this
flow across the International Boundary, both surface and sub-
surface, is of some concern to local, state, and federal
agencies. As a first step towards addressing these concerns, a
thorough consideration of all available investigations, reports,
raw data, and other pertinent information is needed. This
consideration requires the information to be located,
bibliographically referenced, and sorted into a taxonomic
structure so as to act as a preliminary basis for further
investigations.
This report is a review of all available information on the
Upper Santa Cruz River Basin from the International Boundary to
the Santa Cruz/Pima County line. The report serves as a
referencing tool from which the user can extract and further
scrutinize the information contained within. The structure of
the report is such that a reader can pursue information either by
subject or author.
The report has an open ended structure allowing additions to
the references as new information becomes available. The report
is written in Word Perfect 4.1 and is contained on floppy disks
for addition and review of the data base and/or duplication of
any sections.
-------
PURPOSE AND SCOPE
The purpose of this report is to organize the available
water resources type information for the Upper .Santa Cruz River
Basin and act as a referencing tool for further investigations.
Because water resource information for the Upper Santa Cruz River
Basin is found from many different sources, no current central
referencing tool has the ability to locate all of the information
available. This report attempts to be this central referencing
tool, summarizing the available information, organizing the
information into a taxonomic structure, and providing
bibliographic references. No interpretations of the data are
made and the validity of referenced information is not addressed.
LOCATION OF STUDY AREA
The study area consists of Santa Cruz County, Arizona
(Figure 1, Plate 1). The Upper Santa Cruz River Watershed is
wholly contained inside Santa Cruz County. Because the focus of
the report is the Upper Santa Cruz River Basin and the fact that
no other major watersheds are contained in the county, it's
boundaries were chosen to be those of the study area.
Initially the portion of the Upper Santa Cruz River Basin
contained in Mexico was to be included in the study area as a
focus of this report. However, due to a lack of available
information pertaining to water resources in Mexico, only the
area North of the International Boundary was included.
-------
DISCUSSION
This discussion focuses on the use of the report. The
information contained within is a summary of previous work
including reports, raw data, and personal contacts all referenced
bibliographically.
The taxonomic structure in which the information was sorted
can be seen in figure 2. The four basic sections of the report
are General Information, Geophysical Characteristics, Water
Resources, Water Quality, and Water Systems. Each section
contains sub-sections into which subjects fall.
In the General Information section, sub—sections include a
discussion of locations, population, climate, and land use. In
the Geophysical Characteristics section, sub-sections are broken
into geologic setting and topography. The Water Resources
section of the report is broken into surface water and
groundwater sub-sections. The groundwater sub-section is further
broken into hydrogeologic setting, aquifer properties, and well
information. A Water Quality section contains general water
quality, surface water quality, groundwater quality/inorganic,
groundwater quality/organic, and microbiological characteristics.
The last section of the report. Water Systems, is divided into
water use, waste water systems, and distribution systems.
The subject focus of each section and sub-section can be
seen in figure 2. The structure of the report is such that
figure 2 acts as a subject reference where the reader can find
the section and sub-section where specific desired information
may be found.

In the back of the report is the bibliographic reference
which is numbered in accordance with the summarized information
in the body. The bibliographic reference is sorted in two ways;
1) By report reference number. The reader finds the subject of
interest in one of the sections or sub-sections of the report and
notes the report reference number preceding _. the desired
information. The reader looks in the first bibliographic
reference section which is sorted by reference number and finds
bibliographic information on the desired information. The
reference numbers preceded by an "r", emphasize the water
quality, water systems, and geology of Santa Cruz County,
Arizona. Limited information about the other sections in the
taxonomic structure are also included in the "r" references. The
numbered references without an "r" preceding the number contain
information on every section in the taxonomic structure except,
the water quality section. 2) By Author. The reader starts in
the second Bibliographic Reference Section which is sorted by
author last name, and notes the appropriate reference number
preceding the author. The reader then finds this same reference
number in the sections and sub-sections in the body of the report
and scans the available information by that author.
The report is written in WordPerfect 4.1 and is contained on
the floppy disk included with the report. Each section and sub-
section of the report is found in it's own sub-directory. A tree
listing of the sub-directories is shown in figure 3. The report
is written with the ability to be expanded as more information

Water resources data for the given water year for Arizona consist
of records of stage, discharge, and water quality of streams;
stage, contents, and water quality of lakes and reservoirs;
measurements of ground-water levels; and quality of water from
selected wells. Also included are discharge data for crest-stage
partial-record station and water-quality data for partial-record
stations. Locations of the gaging stations and water quality
stations are shown. Additional water data were collected at
various sites, which are not part of the systematic data-
collection program, and are published as miscellaneous
measurements or miscellaneous water-quality analyses. These data
represent that part of the National Water Data System operated by
the U.S. Geological Survey and cooperating State and Federal
agencies in Arizona.
Records of discharge or stage of streams and contents or stage of
lakes and reservoirs were first published in a series of U.S.
Geological Survey water-supply papers entitled "Surface Water
Supply of the United States." These water—supply papers were in
an annual series through water year: 1960 and then in a 5—year
series for 1961-65 and 1966-70. Records of chemical quality,
water temperatures, and suspended sediment were published from
1941 to 1970 in an annual series of water-supply papers entitled
"Quality of Surface Waters of the United States." Records of
ground-water levels were published from 1935-1974 in a series of
water-quality papers entitled "Ground-water Levels in the United
States."
For water years 1961-74, streamflow data were released by the
Geological Survey in annual reports on a State-boundary basis.
For water years 1964-74, water-quality records were similarly
released either in separate reports or in conjunction with
streamflow records.
Beginning with the 1975 water year, water data for streamflow,
water quality, and ground water are published in official Survey
reports on a State-boundary basis. These official Survey reports
carry an identification number consisting of the two—letter state
abbreviation, the last two digits of the water year, and the
volume number.

contaminants were found and at what levels, also an
interpretation of the reliability of the results based on QA/QC
procedures. Trichlorof luoromethane was detected in 5 of 6
monitoring wells and in the Yubeta well. The Yubeta well was
resampled on April 28, 1988 and the results showed all compounds
below detection. The upgradient monitoring well UMW-1, showed
five VOC's present, three exceed the Arizona Action Levels, (1,1-
DCE, TCE, trichlorofluoromethane). Downgradient wells DMW-4 and
DMW-8 showed two VOC's above the Arizona Action Level (1,1,1-TCA,
trichlorofluoromethane) . The monitoring well DMW-6 showed
detectable concentrations of two VOC's (trans 1,2-DCE, TCE).
Monitoring wells DMW-5 and DMW-50 showed no significant change
from the previous semiannual sampling results.
