                              ABSTRACT
An investigation to determine the ground water pollution problems
which exist in the states of Arizona, California, Nevada, and Utah
was conducted.  Data were obtained through an extensive review of
the literature and through interviews with engineers, scientists and
governmental officials concerned with water pollution in the four
states of the project area.

Mineralization of ground water is the most prevalent factor in the
degradation of ground water quality in the project area.  Large
quantities of ground water in each of the four states are undesirable
for many uses because of excessive mineralization.  Much of the
mineralization of ground water is a result of natural processes.
Some is caused by man's activities—irrigation, oil field brine dis-
posal, and over-pumping of aquifers are conmon causes of mineraliza-
tion.  Usually the degradation is caused by an excess of total
dissolved solids, but at some locations, specific toxic substances
(of natural origin) are also found in the ground water.  Boron and
arsenic in toxic amounts have been found in ground water, especially
in Arizona and Southern California.  Of the various forms of pollu-
tion of ground water caused by man's activities, nitrate is probably
most prevalent in the project area.

A listing of conditions causing ground water pollution in the pro-
ject area is included in the report.

This report was submitted in fulfillment of project no. 16060 ERU,
contract no. 14-12-919 under the sponsorship of the office of
Research and Monitoring, Environmental Protection Agency.

                             CONCLUSIONS
1.  The general public and many public officials have inadequate know-
ledge of the factors affecting the quality of ground water and the
limitations on ground water development.

2.  All ground waters contain dissolved minerals.  The natural
leaching of soil by percolating waters in arid regions often causes
natural accumulations of minerals which limit the usefulness of the
ground water.  The use of water by native vegetation increases the
mineral content of the ground water.  These and other natural pro-
cesses are a major factor in the pollution of ground water in trie
project area.

3.  Throughout the project area, there exist many water-bearing forma-
tions at considerable depth below the ground surface which contain
minerals in high concentrations.  Whenever these waters issue forth
through deep oil well drilling or natural springs (often "hot") , they
may represent an important source of ground water pollution.

4.  It is impossible to adequately consider problems of ground water
quality without also considering ground water quantity.  Water of
poor quality if in very limited supply may have little economic signif-
icance; and waters of good quality which are over-developed may bring
connate brine or sea water into the fresh water aquifer, or affect the
ground water in other ways .

5.  There is an ever-in ere as ing demand for water in the project area.
Many of the ground water supplies have been developed beyond the "safe
yield" limits and this often results in increased mineralization.  Much
of the water is also "re-used" several times with an accompanying de-
crease in quality.  These trends will continue in the future with a
continued degradation of the ground water.

6.  Irrigation of agricultural lands provides great benefit to the
economy and progress of the project area.  This is not without "cost"
in water quality, since the leaching process which maintains a neces-
sary "salt balance" in the agricultural soil continually adds salt to
the irrigation return flow, and thus to the ground water supply.  Min-
eralization of the ground water, both from irrigation and natural
sources is the greatest ground water quality problem in the project
area .

7.  Nitrates in the ground water are at dangerously high levels at
many locations in the project area.  The source of these nitrates is
usually not known, but most likely sources are (a)  solid waste land
fills, (b) land disposal of various wastes, (c)  fertilizer

-------
applications, or (d)  sewage effluent which gets into  the  ground water,

8.  Boron is found in natural ground water at many locations  in Cali-
fornia, Arizona, and Nevada.  It is a serious problem in  some areas
since it is toxic in relatively low concentrations to many plants.

9.  Excessive concentrations of fluorides are found in ground water
at a number of locations in the project area.

10.  Iron, manganese and arsenic are present in ground water  at a few
locations in the area studies .  They are usually of natural origin .

11.  Phenols, gasoline and similar products have been found in  the
ground water at a few locations, and represent a constant hazard be-
cause of their widespread use .  An underground gasoline leak  in the
Los Angeles area caused great damage to ground water  over a rather
large area.  At latest report,  the source had not been clearly  deter-
mined even after exhaustive studies since the first detection in 1968.

12.  Pesticides and bacterial pollution have not been known to  travel
appreciable distances in ground water,  and have not been  reported as
representing a serious problem at any location in the study area.

13.  Problems of ground water pollution vary greatly  in magnitude and
extent.  For example, mineralization is a broad general problem
throughout the entire arid region, whereas injection  of a particular
pollutant at a given point is usually a localized problem.  Establish-
ment of priorities for research or control measures should be care-
fully considered with this in mind.

                            SECTION II

                          RECOMMENDATIONS


1.  Establish a national education and information program specifi-
cally oriented toward protection of ground water quality.

2.  Update and extend the work of McGuinness, reported in USGS Water
Supply Paper No. 1800, in order that quantitative determinations of
ground water development potential may be available for the entire
U.S.

3.  Conduct investigations, similar to those reported herein, to iden-
tify the ground water pollution problems in all of the remaining parts
of the U.S., with first efforts to be concentrated in the areas of
greatest ground water development and greatest pollution hazard.

4.  Initiate expended research efforts aimed at the solution of
ground water pollution problems with emphasis on those problems most
likely to achieve the most immediate and important impact.  For de-
tailed research recommendations, refer to Section VII herein.

5.  In cooperation with the various states, develop and establish
quality control criteria and enforceable standards to protect ground
water quality throughout the U.S.  In arid regions it is particularly
important that the natural mineralization processes be recognized if
the water resources are to be effectively used.

6.  Recognizing the long-term disastrous results of accidental leak-
age such as the gasoline leak of 1968 in the Los Angeles area, the
appropriate public officials should take steps to establish detection
facilities and a disaster plan for use in the event of such a catas-
trophy at any location in the future.

                              SECTION III

                             INTRODUCTION
Ground water is used as a water supply by about two-thirds of the peo-
ple in the United States .  In many locations, ground water is the only
economical source of water.  In spite of the fact that ground water is
used by many people, it is not well understood by the public, and the
pollution problems connected with ground water are not understood very
well at all.  It is probable that many people cause pollution of ground
water unknowingly, and consider the quality of ground water as re-
sulting from natural causes.  A considerable amount of ground water
pollution is the result of natural phenomena which have been taking
place over a long period of time.  On the other hand, much pollution
of ground water is the result of careless or deliberate acts of man.

Generally the pollution of ground water takes place slowly because the
movement of the ground water is very slow and it often takes a long
time to distribute a pollutant throughout a large volume of ground
water.  However, once the ground water is polluted it is difficult and
time consuming to remedy the situation.  For this reason, it is gener-
ally wise to prevent pollution of ground water rather than to remove
it after it is already in the water.  Recently a national magazine
devoted one issue to the problems of ground water pollution (1)  and
evidence indicates that the ground water quality is deteriorating in
many areas.  Ground water pollution is a problem of national concern,
and research and public action are needed to help preserve our ground
water resources .

Whatever the cause of pollution, the ground water resource may be
rendered unfit for use if corrective measures are not taken.  Correc-
tive or remedial measures can only be effectively planned and evaluated
if knowledge is available delineating the extent and kind of pollution
which exists.  This report is intended to provide such knowledge for
the Southwestern part of the United States—the states of Arizona,
California, Nevada and Utah.  The report will also relate briefly to
potential problems, which could develop in the future, and with recom-
mendations for research related to the preventing or correcting of
ground water pollution.

-------
                             SECTION IV

                     DESCRIPTION OF PROJECT AREA
The project area includes the states of Arizona, California, Nevada
and Utah—the most arid part of the United States.  Within the bound-
aries of the area are vast deserts, several large salt lakes, high
mountain ranges and productive agricultural areas.  The project area
represents an area of 468,000 square miles, about 13% of the area of
the United States.  It includes the roost populous state (California)
and one of the least populous (Nevada) .  Ground water use in the pro-
ject area is about 40% of the total for the United States.

                             Physiography

The project area is characterized by a wide variation in physiographic
features.  Dominating the area are several mountain ranges (including
the Sierra Nevada, The Wasatch, and The Uinta Mountains), a large
closed desert basin (known as the Great Salt Lake Basin), and the vast
Colorado Plateau.

Using the classification of Thomas (2) who divided the U.S. into ten
Ground Water Regions (consolidating the 21 Physiographic Regions of
Meinzer (3), and the 24 Physiographic Regions of Fenneman (4)), it is
seen that the study area includes areas classified in four of the
basic Ground Water Regions:
           (1) The Alluvial Basins
           (2) The Western Mountain Ranges
           (3) The Colorado Plateau
           (4) The Columbia Plateau

It is noteworthy that these regions do not have a single closed bound-
ary—especially is this true of the first two—but include areas at a
number of locations, as dictated by the occurrence of the physiographic
features which give them their name.  Thus, the major mountain ranges
in the study area; The Sierra Nevada, and The Wasatch, are classified
as being in the Western Mountain Range Region.  The extensive alluvial
deposits at the base of these mountain ranges are in the Alluvial
Basins Region .  Actually, the Alluvial Basins Region includes the
Coastal Plains of California, the Central Valley of California, most
of the state of Nevada, all of the state of Utah west of the Wasatch
Range, the Colorado Desert area in Southeastern California, and the
Colorado Drainage (including the Gila River and its tributaries) in
Arizona.  The Colorado Plateau Region includes a large area in North-
eastern Arizona and Southeastern Utah.  Only a small part of the study
area is included in the Coluntoia Plateau—a small area of volcanic
deposits in Northeastern California.  It is in the Alluvial Basins that
most of the ground water supplies are found.

-------
The physiographic features have a pronounced effect upon the quantity
and quality of ground water available.  In the Alluvial Basins, the
recharge potential is often more important than the extent and charac-
ter of the alluvial deposit.  Geologic conditions in the Western
Mountain Region and in the Colorado Plateau have a great effect on the
quality and quantity of ground water.  For example, the escarpment
along the southern boundary of the Colorado Plateau is known as the
Mogollon Rim, and is the source of some rather large springs which
contribute a considerable flow of water (which is of poor quality)  to
the Salt River, a tributary of the Gila River.  At most locations in
the Colorado Plateau, the potential ground water development is very
limited, but at a few locations, because of faulting or other under-
ground conditions, fairly good supplies of ground water may be
developed.

                              Population

The study area includes several large urban areas with a high degree
of development, and a large demand for water.  It also includes vast
unpopulated desert areas.  The present population of the area is over
23 million people.  The population by states is as follows:

Rapid growth has occurred in each of the states since 1960 as shown
by the above figures.

                               Climate

The climate of the project area is highly variable .  Some of the moun-
tain areas of California and Utah have relatively high rainfall, and
at the higher elevations support alpine type of vegetation.  In the
North Coastal Basin of California, an annual precipitation of over 80
inches occurs at several locations .  For the most part, however, the
project area has an arid or semi-arid climate with very limited
precipitation.  Large areas of all four states receive less than 10
inches of precipitation annually.  The average annual precipitation
over the project area is shown in Figure 1.  The sparse moisture con-
dition of much of the area not only has a great effect on the water
supplies and the ground water re-charge, but it also has a pronounced
effect upon the characteristics of the soil mantle throughout the pro-
ject area.  In those areas where precipitation is high, the soluble
minerals are leached from the soil, whereas in areas of low precipita-
tion this has not occurred and ground waters are often salty—some-
times to the point of severely limiting their usefulness.

-------
The high simmer temperatures, especially in the desert regions where
natural drainage of the land is restricted, also has a detrimental
effect on ground water quality.  The desert regions of the south half
of the project area experience temperatures above 100°F for a consid-
erable part of each year.  The average July temperature at many
locations in Arizona and Southern California is over 90°F.

                                Geo logy

The significant geologic features of the project area from a ground
water point of view might be briefly described as:   (1)  The Colorado
Plateau, underlain with sedimentary rocks of variable characteristics
but with limited ground water potential.  (2) Vast deposits of alluvium
along the Colorado River and its tributaries in Arizona and Southern
California; along the Sacramento, and San Joaquin Rivers at the base
of the Sierra Nevada Range; in the plains of the California Coastal
Basins; and throughout the Great Basin area, especially in the area of
the ancient Lake Bonneville.  (3) Scattered formations of volcanic
lava flows and ash beds, usually not of much significance in the
ground water picture in the project area because of their erratic and
discontinuous character.

A brief discussion of the geologic features of the project area
follows below, particularly as related to the ground water potential
from a quality and quantity stand point.  Most of the material is
digested from reports of the Water Resources Council (5, 6, 7, 8, 9,
10, 11, 12) the U.S. Bureau of Reclamation (13, 14), and the O.S.
Geological Survey (15, 3), Thomas (2, 4), and Meinzer (3).

RECENT AND OLDER ALLUVIUM

Ground water occurs in geologic formations ranging from Precambrian to
Recent.  Most of the important ground water developments throughout
the area of the project are in the alluvial deposits, many of which
are of relatively recent origin.  Some older deposits underlie the
recent alluvium, particularly in the Colorado River delta along the
lower reaches of the river in Arizona and California.

Outside of The Lower Colorado River drainage, the project area con-
tains many different ground water basins.  The basins are principally
valley areas, surrounded in whole or in part, and underlain at depth,
by virtually impermeable rock.  The sedimentary fill of most ground-
water basins is alluvium, consisting of permeable alluvial-fan and
flood-plain deposits, and less permeable lake and swamp deposits.

Portions of many of the basins had at one time closed or restricted
drainage, and lakes or playas formed in the central parts of the
valleys.  As a result, lakebed deposits, consisting of several hun-
dreds of feet of clay, silt,  sand, marl, and evaporites, occur within
the older alluvium at many localities .  it is sometimes difficult to

                                  10

-------
differentiate between the older alluvium and the older indurated
sediments, and much of the material ascribed to the older alluvium,
beyond a depth of several hundred feet or below the lakebeds, may
actually be the older indurated sediments.  The higher yielding
sands and gravels of the older alluvium are the principal sources of
taost of the ground water produced.

Beds of marine origin occur at shallow depths in some coastal basins,
and permeable Quaternary basalt is the principal aquifer in several
basins in the northeastern part of California.  In some areas the
effective depth of the ground-water reservoir is limited by the pres-
ence of tightly packed sediment of very low permeability; in other
areas effective depth is limited by the presence of underlying saline
water.

OLDER INDURATED SEDIMENTS
For the purpose of this report, the older indurated sediments arbi-
trarily include all of the sedimentary formations which underlie the
older alluvium and rest upon the bedrock forming the floors and
marginal uplands of the basins in southwestern Arizona.  These deposits
probably range in age from late Cretaceous to middle Tertiary, but may
also include isolated bodies of older sedimentary rocks.

Relatively few wells fully penetrate the older indurated sediments;
consequently, except in a few areas, very little is known about these
formations.  Mast of the materials are probably similar lithologically
to the lower portions of the older alluvium, but are distinguished
from it by their greater degree of induration and by their faulted and
tilted structure.

VOLCANICS
Volcanic formations of diverse ages are common in the project area,
occurring principally as lava flows and associated ash beds .  In some
locations, these accumulations may be several thousand feet thick.

Volcanic materials are often highly fractured or porous,  thus pro-
viding permeable zones capable of storing and transmitting ground
water.  As a rule, however, aquifers within volcanic formations are  of
an erratic and discontinuous character.  Occasionally, a  shallow well
obtains water from highly fractured zones.  Most wells, however, must
penetrate an entire sequence in order to collect enough water for local
use.

Available analyses indicate that water from volcanic formations is
generally low in dissolved solids and that it is of good  to excellent
quality for most uses, but is usually limited in quantity to livestock
or domestic uses.
                                   11

-------
PLATEAUSEDIMENTARY ROCKS

There are many permeable formations that serve as aquifers in the thick
sequence of sedimentary deposits underlying the Plateau region of
Arizona and Utah.  These formations may be of great importance to a
given community or to a particular stock or mining enterprise because
in the broad expanse of area in the Colorado Plateau, water is ex-
tremely difficult to locate and develop.  The total present and po-
tential development of water, quantitatively, in this area is quite
limited except in a few local situations.

                        Surface Water Supplies

It is not the purpose of this report to discuss the supplies of surface
streams in the project area.  It is important, however, to state simply
that the ground water and surface waters are often closely related to
each other.  Many streams are fed in part by springs from ground water.
Many ground water reservoirs are replenished by recharge from surface
waters.  In some locations, a surface stream may disappear entirely
by infiltration into an alluvial deposit as the stream leaves the
mountain reaches of its channel and enters the valley.  In some areas,
such as the Salt River Valley of Arizona, the quality of ground water
may at times be of such a poor quality it cannot be used unless it is
mixed with higher quality surface water.

In full utilization of our water resources, it will often be necessary
to consider both surface and underground supplies used in conjunction
with each other.  For the'purpose of this report, dealing with ground
water pollution, the surface waters will not be considered further at
this time.

                        Ground Water Resources

The importance of ground water pollution bears a direct relationship
to the quantity of ground water available for development as well as
the quantity presently being used from ground water.  Consequently,
in the paragraphs which follow, the ground water resources within the
project area will be considered in some detail.  Each of the four
states will be discussed separately.

ARIZONA

The major ground water producing areas of Arizona are located in the
alluvial deposits which are associated with the river systems in the
Southwestern part of the state.  The Northeastern two-fifths of the
state has limited ground water potential because of the geologic
conditions already described for the Colorado Plateau region.  The
areas of heaviest use generally coincide with the areas of greatest
potential.  As a matter of fact, considering Arizona as a whole, the
ground water withdrawals exceed the recharge throughout most of the

                                  12

-------
state, and water levels are, therefore, declining.

The U.S. Geological Survey, the U.S. Bureau of Reclamation, and the
Arizona State Land Department have conducted detailed studies of
ground water supplies in Arizona.  For the purpose of this report,
Arizona has been divided into five major hydrologic basins (Fig. 2) ,
and various reports from the many separate ground water basins are
grouped under these five basins herein.  Some of the reports referred
to are rather old and some of the studies on which the reports are
based are more detailed than some of the others.  For this reason,
much of the quantitative information relating to either quantity or
quality of water available is generalized.  An attempt has been made
to update material from the older reports by referring to some of the
more recent ones such as those prepared by the U.S. Bureau of Reclama-
tion in 1965  (13), the Pacific Southwest Interagency Committee of the
Water Resources Council (9, 10), the Arizona State Land Department
(16, 17, 18, and others), and the U.S. Geological Survey (15 and
others).  Figures on ground water use generally reflect conditions as
of about 1962, and it should be borne in mind that the rates of with-
drawal have probably in many instances increased during the period
since 1962, especially in view of the years of severe drouth which
have occurred in Arizona during this period.

The withdrawal of ground water varies from year to year, but it is
estimated that there are about 5.7 million acre-feet of water being
withdrawn annually from the ground water supplies of Arizona.  Only
about 50,000 acre-feet (or about one per cent of the state total)  is
taken annually from the Colorado Plateau and the transitional zone
bordering on the Colorado Plateau.  As pointed out in the previous
sections of this report, the geologic formations in the Colorado Pla-
teau and adjoining transitional zones offer a very limited ground
water potential, and most of the wells which have been drilled have
limited capacity, usually producing relatively small flows.  On the
other hand, the Alluvial Basins contain vast deposits of alluvial
material with high permeability and extensive water storage potential.
A brief discussion of the ground water supply potential for each of the
five major hydrologic basins of the state is summarized in the para-
graphs which follow.

Central Gila River and Adjoining Mexican Drainage

Of the five hydrologic basins in Arizona, this one contains the areas
of greatest development and use of ground water,  as well as the areas
of greatest overdraft on the ground water with all of its attendant
water quality problems.  Water supplies in each of the ground water
basins are discussed separately below.

Salt River Valley.  The Salt River Valley contains the most concentrat-
ed agricultural and urban water-using area in Arizona.  Surface and
ground water provide irrigation water for more than 500,000 acres of
land.  It is a principal part of the largest area of ground water

overdraft in Arizona.  More than 2,500 wells pump water from the
ground water supply.  The wells vary in depth from 300 feet to about
2,800 feet, and pump lifts range from about 200 feet to over 500 feet
(13, 19, 20, 21, 22).  Both surface water and ground water are inade-
quate to meet the needs of the area served, and the ground water
levels are declining rapidly.  Declines of ground water level were as
much as 150 feet in 1950-60 (15), resulting in an average decline in
some areas of 15 feet per year.  Water importation is obviously
necessary, unless pumping of ground water is curtailed.  The use from
ground water annually in the Salt River Valley was reported by USER
(13) as about 2,200,000 acre feet in 1962 but it has decreased since
that time.  3h 1968 it was reported as 1,264,000 acre feet (23).  It
is used for irrigation and as a domestic supply for the Phoenix -
Tempe - Mssa metropolitan area.

Lower Santa Cruz Area.  This area borders the Salt River Valley on the
South.  It includes a large part of the Gila and Santa Cruz River
Plain above the confluence with the Salt River.  The deep alluvial
deposits along the Gila and Santa Cruz Rivers provide a great ground
water producing and storage area.  Hoxvever, in this basin, as in the
Salt River Valley, the ground water is heavily over-developed.  The
annual use of ground water in this basin is about 1,150,000 acre feet.
The combined use from ground water in this area and the Salt River
Valley represents about 2/3 of the total ground water use of the State
of Arizona.  As in the Salt River Valley, ground water withdrawals
greatly exceed recharge, and the vast underground water supply is
being depleted by  "mining".  Declines in the i^ater levels during the
1950-60 decade ranged from around 20 to more than 100 feet, with areas
of greatest decline  in tile Southwestern part of the area, near Stan-
field; and areas of least decline along the Gila River.

Upper Santa Cruz Area.  This area includes the upper Santa Cruz River
Basin in Pima and Santa Cruz Counties.  The city of Tucson is located
in this area.  Ground water is pumped heavily for irrigation in a strip
of land 1  to 2 miles wide along the Santa Cruz River north of Tucson,
and for municipal and industrial use in the vicinity of Tucson.  Water
in this basin is taken from both the older and younger alluviums and,
in minor amounts, from the older indurated sediments.  In some loca-
tions, rapidly lowering water levels have virtually exhausted the
usable ground water storage within the younger alluvium (13) .  Total
estimated annual pumpage from this basin for all uses is about 210,000
acre-feet.  Present withdrawals are greatly exceeding the available
recharge, and ground water levels are declining throughout most of the
basin.  Wells are being drilled into the deeper sediments in search of
a water supply.  Some wells as deep as 2,500 feet have been reported,
and considerable deep drilling is likely in the future .  Studies of
artificial recharge of the aquifers are underway (24, 25) .  Ground
water hydrology of the San Xavier Indian Reservation, Southwest of
Tucson is reported by Heindl and White (26, 27).  Turner and others
 (28, 29, 30) have reported on the ground water conditions in the Santa
Cruz Basin .

                                  15

-------
Avra-Marana Area.  This area, located northwest of Tucson, has had
extensive ground water development (31, 32) .  The ground water is
produced primarily from sands and gravels in the older alluvium.
Water levels have been generally declining, with an average of about
1 to 2 feet per year in the southern part of the area, compared with
about 10 feet per year in the northern part, near Eloy.  The ground
water withdrawal in this area is about 175,000 acre feet per year,
and the rate of withdrawal greatly exceeds the recharge .

Waterman Wash.  Waterman Wash is a tributary of the Gila River,
joining the Gila downstream from the Santa Cruz River.  It is an area
of relatively recent ground water development—which was in its early
stages in 1950.  Wells into both the older and younger alluvium pump
large quantities of water for irrigation (19, 33, 34)  .

The pumpage of ground water increased rapidly to about 65,000 acre
feet in 1961, then levelled off.  In 1968 about 55,000 acre feet were
withdrawn from the basin.  Ground water levels continued to decline at
about the same rate throughout the entire period 1956 to 1968, and it
is evident that withdrawals exceed the recharge.

Gila Bend - Rainbow Valley Area.  The ground water developed in this
area is obtained mainly from the younger and older alluviums (35, 36) .
Some of the newer wells have been drilled into the older indurated
sediments.  The ground water levels have been steadily declining for
a number of years, with wells near the river, where recharge occurs
most readily, showing the least decline .  Total annual withdrawal
from the ground water in this area reached a peak of about 250,000
acre feet in 1960 and dropped to 150,000 in 1968.  Ground water
withdrawals exceed the recharge.

Harguahala Plains.  The Harquahala Plains lie along Centennial Wash,
which enters the Gila River from the north at Gillespie Dam.  Develop-
ment of this area has been rather recent, having only begun in 1951.
By 1960, sixty irrigation wells were pumping a total of about 90,000
acre feet of water per year in some locations near the center of the
cultivated area  (37) .  The annual gross pumpage is now estimated at
about 175,000 acre feet per year, and the withdrawal greatly exceeds
the recharge, but there are probably several million acre feet of
ground water in storage (Metzger 38)  .

McMullen Valley.  The principal water bearing aquifer in this valley
is the older alluvium.  Well depths range up to 2,000 feet.  Land
development in this valley has increased greatly in recent years,
accompanied by increased ground water development (Kam 39 and Briggs
40).  Prior to 1950 the ground water use in the basin was about
3,000 acre feet per year,  whereas the use in 1968 was about 107,000
acre feet.  Water levels have declined, and it is evident that with-
drawals of ground water are considerably in excess of the recharge.
                                  16

Papago Indian Reservation.  The Papago Indian Reservation is largely
in Pima County, with small areas in Maricopa and Final Cbunties (41).
It contains about 4,300 square miles—a vast area including most of
the region between Tucson and Ajo, and south of Casa Grande all the
way to the international boundary with Mexico.  The deep alluvial fill
in the valleys appears to be the main aquifer on the lands of the
reservation.  The fill consists of silt, sand and gravel, with varying
amounts of clay, and varies in thickness from 350 feet to itore than
1,000 feet (42, 43, 44, 45) .  The major water use on the reservation
has been near Chuichu  (12 wells reported in 1961) and near Papago
Farms (7 wells reported in 1961) .  Declining water levels in the area
of Chuichu, at the northeast corner of the reservation, has caused some
wells to fail, which reduced the land under cultivation.  According
to the U.S. Bureau of  Reclamation, the declines were caused by heavy
pumping in the area just outside the reservation near Chuichu (13).

Ground water pumpage in the reservation area is estimated at about
10,000 acre feet per year.  It is believed that there are a number of
other valleys within the reservation where ground water supplies can
be developed.  The declining water levels near Chuichu reflect a local
condition and do not indicate that the potential water development of
the reservation has been exceeded.

Upper Gila River and Adjoining Mexican Drainage

This region covers a large area involving drainage into the Upper Gila
River and the Willcox  Basin (a closed basin) and the Douglas Basin
which drains into Mexico.  It also includes the transitional zone be-
tween the Mogollon Rim and the Salt River Valley.

San Pedro Basin.  Both the younger and older alluvium are important
aquifers in the San Pedro Valley.  The younger alluvium varies in
thickness up to 150 feet, and the older alluvium varies from a few
feet to over 1,500 feet thick.  A few wells derive water from the
older sediments  (46, 47,  48).

Water levels, especially  in the younger alluvium, show considerable
fluctuation but no long term trends are discernible .  The total
pumpage from the Basin in  1968 was estimated at 71,000 acre feet.
Available information  indicates that the recharge is approximately
equal to th^withdrawal.

Araviapa Valley.   This valley contains alluvial deposits containing a
fairly good water  supply.  Water  is pumped to supplement stream diver-
sions, with the  amount varying from year to year.  Three thousand four
hundred acre feet were pumped in  1961.

San Simon Basin.  The  major aquifer of the San Simon Basin is the older
alluvium.  A thick  "blue  clay*' divides the alluvial fill into an upper
unconfined layer and a lower confined portion.  Sand and fine gravel
interbedded with thick lakebed deposits of silt and clay have been

                                   17

-------
reported to a depth of 1,230 feet.  These deposits are the major
source of the waters of this basin (49, 50, 51, 52, 53).  Pressures in
the artesian aquifers have shown declines for many years, especially
since 1952.  East of Bowie, the pressure head has declined more than
100 feet since 1915, while near San Simon the decline has exceeded 80
feet, with 70 feet of this occurring since 1954 .  Annual pumpage by
1968 had exceeded 80,000 acre feet, and the accelerated rate of
decline of artesian pressures indicates that withdrawals greatly
exceed the basin recharge .

Duncan Basin.  The Duncan Basin, in Arizona, is part of the Duncan -
Virden Valley, which extends into New Mexico.  It is part of the upper
Gila River drainage basin .  The major aquifer in the valley is the
younger alluvium which lies in the channel and flood plain of the
Gila River (54, 55) .  Irrigation wells range to about 300 feet depth,
and the ground water table has been rising slightly since 1952 indi-
cating that the recharge exceeds the withdrawal.  Withdrawal has
remained fairly constant for the ten years preceding 1969; and is
estimated at 25,000 acre feet annually.

Safford Valley.  The Safford Valley, located along the Gila River, has
a major ground water aquifer located in the younger alluvium along the
river  (56) .  The younger alluvium, ranges in thickness from a few feet
along the periphery of the Gila River flood plain to about 110 feet
near Safford.  The older alluvium underlies the channel and flood
plain deposits, and has much lower specific yield than the younger
deposits.  Wells in the younger alluvium are quite shallow—up to 120
feet—but those in the older alluvium range from 200 to 1,700 feet
deep.  Most of the wells in the older alluvium draw water from con-
fined aquifers (57, 58, 59) .  Several deep wells, drilled into the
older sediments as deep as 3,500 feet, have encountered hot confined
waters .

Water levels fell in the area in the early 1950's to a low in 1957.
For the years following 1957 there has been a general rise in the
water levels, although there has been a decline in several of those
years.

The ground water in this basin is pumped as a supplemental supply to
the waters of the Gila River.  The amount of withdrawal  in years of
low river flow may be as high as 160,000 acre feet, but  in years of
high river flow may be less than 100,000 acre feet.  On  the average,
the withdrawals do not exceed the recharge .

Verde Valley.  The Verde Valley flows off the Colorado Plateau and
southward to the Salt River near Phoenix.  The upper Verde Valley is
located between the Black Hills and the Mogollon Rim.  The principal
aquifer within the valley is the Verde formation, which  is commonly
under confined conditions.  Most wells draw water  from the permeable
limestones and sandstones of the formation.  Some  high capacity wells

                                  18

-------
(up to about 2,000 gallons per minute) are prevalent in the valley.
Specific capacities of wells drawing water from the limestone are
generally low.  More than 100 wells draw water from the Verde Forma-
tion.  Further north, in the upper part of the drainage basin, near
Sedona, wells generally 200 to 600 feet deep obtain water from sand-
stone of the Supai Formation, which still further north underlies the
Coconino Sandstone (60) .  It is estimated that the annual pumpage
from ground water in this valley is about 25,000 acre feet.

Chino Valley.  Chino Valley, located about 20 miles north of Prescott,
contains an artesian basin about 3 miles wide and 7 miles long.  The
main aquifer material consists of buried lava flows, volcanic ash and
cinders, interbedded with older alluvium.  Lonesome Valley is included
in the area known as Chino Valley, though a ground water divide
separates the two valleys (61) .  Groundwater in this area comes from
the older alluvium.  A total of about 18,000 acre feet is pumped from
this valley annually, and the ground water level is declining
slightly, indicating that the withdrawals slightly exceed the recharge.

Big Chino Valley.  Big Chino Valley extends a distance of 30 miles or
more to the northwest of Sullivan Lake and the town of Paulden.  Ground
water used in the valley is withdrawn from an alluvial fill consisting
of lenticular silt and clay, sands and gravels, and frequently cemented
conglomerate beds, inter-bedded with lava flows.  Pumpage is usually
about 20,000 acre feet per year (23)  .  The water level has not de-
clined over a period of years prior  to 1969, and it appears that the
withdrawals do not exceed the re-charge.

Mile ox Basin.  The Willcox Basin, located in Southeastern Arizona, has
no exterior drainage.  The major aquifer in the area is the older
alluvium, in which both confined and unconfined waters occur  (13, 62,
63).  Thick clay sequences, containing gravel and sand lenses with
water under pressure, are common within the alluvium.  Surface and
ground water move generally toward the Willcox Playa—the low area in
this topographically closed basin.  Ground waters in the Playa area
are of poorer quality than those flowing toward the Playa.  However,
cones of depression created by heavy pumping have intercepted much of
the groundwater which formerly flowed into the Willcox Playa, and
continued heavy punping will reverse the flow away from this area—
bringing the water of poorer quality into many wells.  Pumpage in 1967
and 1968 was estimated at 290,000 acre feet annually.  This exceeds
the annual recharge in the basin.

Douglas Basin.  The Douglas Basin is the southern part of Sulphur
Spring Valley which includes the Willcox Basin on the north and extends
into Mexico on the south.  In this basin, the major aquifer is the old-
er alluvium, which is known to be at least 1,000 feet thick (19, 64).
Depth to water in the basin was reported in 1962 to be generally less
than 100 feet (13) and the water levels are generally declining.
Gross pumpage has increased steadily.  In 1957 the withdrawal from

                                  19

-------
ground water was about 55,000 acre feet,  and in 1969 about 120,000
(23) .

Lower Gila River Valley

Well ton -Mohawk Area.  In the Well ton-Mo hawk area of the lower Gila
River, the ground water is primarily in the younger alluvium (65,
66) .  Pumping of ground water for irrigation declined rapidly in the
early 1950 's and was replaced by surface water diverted from the
Colorado River to the Wellton-Mohawk Irrigation Project.  By 1957
pumping of ground water had virtually ceased.  Subsequent recharge by
return flows of Colorado River water caused water levels to rise to
within a few inches of the land surface necessitating extensive
drainage facilities.  During 1962, sixty-one operating drainage wells
pumped about 208,000 acre feet of ground water, causing an average
decline of 2.7 feet in the water table.  Pumping, for drainage purposes
only, is noxv continued on a regular basis.  Pumping in 1968 was
220,000 acre feet.

Palomas Plain - Dendora Valley .  This includes the area along the Gila
River drainage between the Gila Bend area downstream to the Wellton-
Mohawk area  (19, 67, 68, 69, 70, 35) .  This area has exhibited a
steady increase in the amount of ground water use since 1958—in-
creasing from about 30,000 acre feet in 1958 to about 125,000 acre
feet in 1968.  As with other ground water areas along the Gila River,
this area has deep deposits of younger and older alluvium from which
water is produced.  Some wells as deep as 1,000 feet have been
reported (13) .  No specific information is available regarding recharge
and the balance between recharge and withdrawals .  However, wells
reported in 1969 (23)  did not indicate general water table declines,
and it is, therefore, not likely that the withdrawals have signifi-
cantly exceeded the re-charge if at all.

Ajo Area.  No published reports or description of the ground water
potential are available for this area.  According to the U.S. Bureau
of  Reclamation, 10,000 acre feet of water was used in this area in
1961 for industrial, domestic, and municipal uses (13) .

Colorado River Drainage

Yuma Area .  The Yuma Area includes South Gila Valley, Yuira Mesa, and
Yuira Valley .  The ground water comes from the younger and older
alluvium.  The ground water reservoir is reported to be wedge-shaped
(13), ranging in thickness from about 210 feet at Laguna Dam to about
3,400 feet near San Luis.  The upper portion of this reservoir con-
sists of five deltaic deposits interbedded with coarse river channel
deposits, and is 120 to 400 feet thick.  The prinary development of
ground water is in the South Gila Valley.  Elsewhere, a limited amount
of  ground water is pumped to supplement surface-water diversions from
the Colorado River.  Part of the ground water is pumped in order to

                                  20

-------
drain agricultural lands of the area.  This problem has been accen-
tuated since the increase in irrigation of the lands of the Yuma Mesa
Project of the U.S. Bureau of Reclamation.  Ground water quality has
also improved.  The imported Colorado River water on Yuma Mesa, has
been of higher quality than the existing ground water  (see Brown and
others 71, also Jacob 72, 73) .  The ground water levels have been
rising since 1948.  Hie amount of water pumped from the ground water-
has also been rising steadily—from 22,000 acre feet in 1945 to nearly
270,000 acre feet in 1968.

Ranegrass Plain.  The Ranegrass Plain is part of a broad alluvial low-
land interrupted by low mountains.  The principal water bearing materi-
als are in the older alluviums (16, 74) .  Ground water development in
this area began in about 1951, and within a few years, the annual
pumpage was about 20,000 a.cre feet.  Water levels have declined
slightly in most years since about 1955, and. this general trend indi-
cates that the pumpage is exceeding the recharge.  The difficulty of
locating good wells and the depth to ground water have presented more
extensive development.  Annual pumpage in 1-968, up slightly from the
iranediately preceding years, was about 15,000 acre feet per year.

Bill Williams River Valley.  The Bill Williams River drainage basin is
located west of Prescott and drains directly into the Colorado River.
According to Wolcott, Skibitzke and Halpenny  (75) there is not much
potential for ground water development in this valley.  Most of the
ground water is in the younger alluvium along the river, which has
liirdted storage capability—between 10,000 and 15,000 acre feet.  Their
estimate of ground water use in 1951 was about 1,000 acre feet, but the
U.S. Bureau of Reclamation in 1965 estimated total use in this valley
of  10,000 acre feet per year  (13) .

Other Areas .  There are a number of other isolated areas in the Colora-
do  River Drainage where ground water development has occurred.  Among
these are three small valleys southwest of Prescott—Peoples Valley,
Date Creek Valley, and Skull Valley—, the Kingman area, Big Sandy
Valley southeast of Kingman, and the Chinle Valley in the north-
eastern part of tiie state .  Total ground water use in these areas is
estimated at 30,000 to 35,000 acre feet, per year.

Little Colorado River Basin
This  basin is  sparsely populated.  The communities of Flagstaff, Wins-
low,  Holbrook  and  St. Johns  are  located in this basin.  These communi-
ties  and  the agricultural  areas  near them use water from ground water
sources,  usually as  a supplement to the surface water supplies.  The
principle aquifer  in the basin is the Coconino sandstone, which is
largely developed  in the Mo go lion slope country, south and west of the
Little Colorado River.  Production of sufficient water for irrigation
purposes  has been  limited  to areas in which the sandstone is highly
fractured and  jointed.  However, there are numerous low-production wells
                                   21

-------
that provide water for stock and domestic use.  More than one water-
bearing zone in the Coconino Sandstone has been recorded in some of
the well logs.  Irrigation wells capable of pumping 500 to 2,000
gallons per minute are found in the vicinity of Hunt, St. Johns, and
Snowflake.

Ground water levels within the Coconino Sandstone have shown no sig-
nificant decline; however, in local areas of heavy pumping, a.few^
artesian wells have ceased to flow.  No publisned estimate is available
of the amount of water used from the ground water in this basin, but
it is probably less than 20,000 acre feet per year.

CALIFORNIA
California uses more ground water than any other state of the nation .
Most of the areas of the state have been developed beyond the "safe
yield" of the ground water basins.  However, the available ground-
water storage capacity in California is vast.  Although the storage
capacity of all ground-water basins has not been determined in detail,
it has been established that a capacity of more than 1,000 million
acre-feet exists.  Approximately 570 million acre-feet of that total
is in the San Joaquin Valley above a depth of 1,000 feet, or above
the base of those fresh-water-bearing sediments that do not reach a
depth of 1,000 feet.  Another 150 million acre-feet of storage exists
in southern California—in the Mojave Pdver Basin, Coachella Valley,
and Los Angeles, San Bernardino, and riverside Counties .

Not all of the billion acre-feet of gross storage capacity is usable .
Usable storage capacity has been defined by Poland and others (76) in
part as, "that reservoir capacity that can be shown to be economically
capable of being dewatered during periods of deficient surface supply
and capable of being resaturated, either naturally or artifically,
during periods of excess surface supply.  .  ."  To compute the total
usable storage required the evaluation of such elements as permeability,
econoraics of extraction and of recharge, and the suitability for use of
waters of various qualities.  Available data are inadequate for such
an evaluation in much of the region, but it is currently estimated
that the usable storage capacity of the ground-water basins in Cali-
fornia totals more than 250 million acre-feet.  These figures for gross
and usable storage capacity of the ground-water basins are strikingly
greater than the 77 million acre-feet of gross storage in surface res-
ervoirs that are planned for development by the year 2020, and the 50
million acre-feet of active surface storage that is planned for the
surface reservoirs of the future.

The proportion of usable storage that is presently occupied by ground
water varies areally.  In northern California the annual draft on ground
water is replenished by recharge to the ground-water basins and a large
proportion of the storage capacity is filled.  In many of the basins
in central and southern California, however, annual extractions exceed

                                  22

-------
annual replenishment, and ground-water levels in a year of average
precipitation and pumpage continue to fall,  in the San Joaquin-
Tulare Valley, for example, more than 70 million acre-feet of storage
capacity is presently unwatered.  In general, however, throughout the
region a large proportion of the usable ground-water storage capacity
is still occupied by economically obtainable water, although much of
it is located in areas of little demand.  Considered on the basis of
major hydro logic basins, it is possible to make the generalization that
all 'basins of the state are using ground water at a rate equal-to or
exceeding the "safe ground water yield" except the North Coastal
Basin.  There an estimated 100,000 acre-feet of water annually are
still available for development.  In all other basins of the state the
waters are being "mined,"—or the withdrawals exceed the recharge.

A brief discussion of ground water conditions in each basin is pre-
sented in the following paragraphs.  The basins indicated are also the
Ground Water Sub-Regions of the U.S. Geological Survey  (77)  .  Bound-
aries are indicated on Figure 3.

North Coastal Basin
Most usable ground water in this predominantly mountainous area occurs
in widely  scattered alluvium filled valleys and coastal plains.  The
alluvium consists generally of  lenticular beds of unconsolidated to
semiconsolidated clay, silt, sand, and gravel of Cenozoic age.  The
intervening mountainous areas are underlain by consolidated sedimen-
tary, igneous,  and metamorphic  rocks mainly of Mesozoic age or older.
These older rocks contain  only  small quantities of recoverable ground
water and, therefore,  are  not considered further as a major source of
ground water.

Thirteen valley-fill areas have been identified as significant sources
of ground  water.  The  total area of all 13 valleys is about 1,300
square miles .   The water-bearing deposits range in thickness from 50
to 15,000  feet. Depending on local conditions, recharge infiltrates
at rates of less than  1-1/2 feet per day to more than 10 feet per day
in the upper part of alluvial fans, in stream channels, and in some
areas underlain by volcanic rocks.  The maximum measured depth to
water in the water-bearing deposits is 185 feet.  In several valleys
til ere are  flowing wells .

Total storage  capacity of  the valleys for which determinations have
been made  is nearly 1,000,000 acre-feet, of which about 700,000 acre-
feet is considered usable  (78) . Limiting factors are the possibility
of sea-water intrusion and aquifer materials of low permeability.
Ground water temperature generally ranges from 50°F to 70°F, but
locally is as  low as 43°F  and as high as 178°F .  Total ground water use
in this basin  is estimated to be about 150,000 acre-feet per year.
This is about  100,000  acre-feet less than the safe yield of this
basin (5) . Some characteristics of the North Coastal Basin are given

                                  23

San Francisco Bay Basin

Most usable ground water in the predominantly mountainous San Fran-
cisco Bay Basin occurs in small scattered alluvium-filled valleys
and in larger basins tributary to San Francisco Bay.  The alluvium con-
sists generally of lenticular beds of unconsolidated to semiconsoli-
dated clay, silt, sand, and gravel of Cenozoic age.  The intervening
mountainous areas are underlain by consolidated sedimentary,  igneous,
and metamorphic rocks mainly of Mssozoic age.  These older rocks con-
tain only small quantities of recoverable ground water and, therefore,
are not considered further as a major source of ground water.

In the San Francisco Bay Basin, eighteen valley-fill areas have been
identified as significant sources of ground water.  The total area
of the eighteen valleys is about 2,000 square miles.  The water-
bearing deposits range in thickness from about 100 to 2,000 feet.
Depending on local conditions, recharge infiltrates at rates of less
than 1-1/2 feet per day to more than 10 feet per day in the upper part
of alluvial fans and in stream channels.  The maximum measured depth
to water in the water-bearing deposits is 374 feet.  In several valleys
there are flowing wells.

Total storage capacity of the 14 basins for which determinations have
been made is nearly 4,500,000 acre-feet.  The usable storage capacity
of the five basins for which determinations have been made is nearly
1,200,000 acre-feet  (79) .  Limiting factors are salt-water intrusion,
aquifer materials of low permeability, and water of poor quality.
Ground-^water temperature generally ranges from 50°F to 75°F,  but
locally is as high as 140°F.

Safe ground-water yield for the entire San Francisco Bay Basin is
estimated to be  300,000 acre-feet per year? an annual overdraft esti-
mated to be 70,000 acre-feet exists (5) .  Some characteristics of the
San Francisco Bay Basin are given in Table 2.

Central Coastal Basin

Most usable ground water in the predominantly mountainous Central
Coastal Basin occurs in alluvium-filled valleys and coastal plains, and
in deeper aquifers of Quaternary and Tertiary age .  The intervening
mountainous areas are underlain by consolidated sedimentary,  igneous,
and metamorphic rocks, mainly of Masozoic age.  These older rocks con-
tain only small quantities of recoverable ground water and, therefore,
are not considered a major source of ground water.

In the Central Coastal Basin, 24 areas have been identified as signif-
icant sources of ground water.  The total area of the 24 valley areas
is about 3,500 square miles.  The water-bearing deposits range in

thickness from about 200 to 4,000 feet.  Depending on local conditions,
recharge infiltrates at rates of less than 1-1/2 feet per day to more
than 10 feet per day in the upper part of alluvial fans and in stream
channels and at the outcrops of the deeper aquifers,  The maximum
measured depth to water in the water-bearing deposits is 568 feet.  In
several valleys there are flowing wells.

Total  storage capacity of the 16 basins for which determinations have
been made is more than 20,000,000 acre-feet.  The usable storage
capacity of the 18 basins for which determinations have been made is
more than 7,600,000 acre-feet? the limiting factors are sea-water
encroachment and high pumping life (80) .  Ground-water temperature
generally ranges from 55° to 75°F.

Safe ground-water yield for the entire Central Coastal Basin is esti-
mated  to be 900,000 acre-feet per year;  an annual over-draft estimated
to be  70,000 acre-feet exists (5) .  Some characteristics of the Cen-
tral Coastal Basin are given in Table 3.

South  Coastal Basin
 Most usable ground water in the predominantly mountainous South Coastal
 Basin occurs  in alluvium-filled valleys and coastal plains and in
 deeper  aquifers of Quaternary and Tertiary age.  The intervening
 mountainous areas are underlain by consolidated sedimentary, igneous,
 and metamorphic rocks, mainly of Jfesozoic age.  These older rocks con-
 tain only small quantities of recoverable ground water and, therefore,
 are not considered a major source of ground water.

 In the  South  Coastal Basin, 44 areas have been identified as signifi-
 cant sources  of ground water.  The total area of the 44 valley areas is
 about 3,000 square miles.  The water-bearing deposits range in thick-
 ness from about 50 to 2,500 feet.  Depending on local conditions, re-
 charge  infiltrates at rates of less than 1-1/2 feet per day to more
 than 10 feet  per day in the upper part of alluvial fans and in stream
 channels and  at the outcrops of the deeper aquifers .  The maximum
 measured depth to water in the water-bearing deposits is 799 feet.   In
 several valleys there are flowing wells (81) .

Water in storage (in 1965)  in the basins for which determinations have
been made totals nearly 100,000,000 acre-feet.  The usable storage
capacity was  not determined for the largest basins but where determined,
is more than  800,000 acre-feet; the limiting factors are possible sea-
water intrusion, thin alluvial material, and locally, high pumping
lift.  Ground water temperature ranges from about 55° to 90°F, but
locally is as high as 164°F (5) .

Safe ground-water field for the entire South Coastal Basin is estimated
to be 1.6 million acre-feet per year.  There is no over-draft in the
basin as a whole;  while over-draft occurs in local areas, it is

compensated by artificial recharge in other areas.  Some characteris-
tics of the South Coastal Basin are given in Table 4 .

San Joaquin Basin

Nearly all usable ground water in the San Joaguin Basin occurs in the
alluvium-filled San Joaquin Valley.  The aquifer system throughout the
entire San Joaquin Valley is an integrated system.

•She San Joaquin Valley has a total area of core than 13,COO square
irj.les.  Tne water-bearing deposits are as much as 3,500 feet thick.
Recharge infiltrates at rates of less than 1-1/2 feet per day to about
3 feet per day over most of the valley floor and particularly on the
east periphery of the valley.  The maximum measured depth to water in
the valley is 842 feet.  The aquifer system of approximately 5,000
square miles in the west and central part of the basin is under arte-
sian pressure .

Total storage capacity of the San Joaquin Valley is 33 i-dllion acre-
feet.  The usable storage capacity is 80 million acre-feet,- low
permeability in some areas is considered a limiting factor.  Ground-
water temperature ranges from, about 45° to about 105 F (82) .

Safe ground water yield for the Basin is estimated to be 6,550,000
acre-feet per year.  There is a great over-draft from this basin —
estimated to be 2,500,000 acre-feet annually (5) .  See Table 5 for
details .

Sacramento Basin

Most usable ground water in the predominantly mountainous Sacramento
Basin occurs in alluvium-filled valleys and in volcanic rocks of
Quaternary and Tertiary age.  In this sub-region 21 areas have been
identified as significant sources of ground water.  The total area of
the 21 valley areas is about 6,150 square miles, 5,000 of which is
occupied by the Sacramento Valley.  The water-bearing deposits range
in thickness from about 100 to 2,700 feet.  Depending on local condi-
tions, recharge infiltrates at rates of less than 1-1/2 feet per day to
more than 10 feet per day in the upper part of alluvial fans and in
stream channels.  The maximum measured depth to water is 306 feet.  In
several valleys there are flowing wells .

Total storage capacity of the 17 basins for which determinations have
been made is nearly 55,000,000 acre-feet, of which more than 33,000,000
is in the Sacramento Valley.  The usable storage capacity in the Sacra-
mento Valley is 22,000,000 acre-feet; the limiting factors are aquifer
materials of low permeability, water of inferior quality, and economic
considerations (83)  .  Ground-water temperature generally ranges from
55°F to 75 F as shown in Table 6 .

Safe ground-water yield for the entire Sacramento Basin is estimated
to be 1.6 million acre-feet per year;  an annual overdraft estimated
to be 100,000 acre-feet exists (5) .

North Lahontan Basin
Most usable ground water in the predominantly mountainous North Lahon-
tan Basin occurs in scattered valleys filled with alluvium and material
of volcanic origin.  The intervening mountainous areas are underlain by
igneous rocks of Mesozoic and Cenozoic age.  Those rocks contain only
small' quantities of recoverable ground water and, therefore,  are not
considered a major source of ground water.

In the North Lahontan Basin, eight valley-fill areas have been identi-
fied as significant sources of ground water.  The total area of the
eight valleys is about 1,300 square miles.  The water-tearing deposits
range in thickness from about 250 to 1,000 feet.  Depending on local
conditions, recharge infiltrates at rates of less than 1-1/2 feet per
day to more than 10 feet per day in the upper part of alluvial fans and
in stream channels.  The maximum measured depth to water in the water-
bearing deposits is 192 feet.  In several valleys there are flowing
wells .

Total storage capacity of the seven basins for which determinations
have been made is nearly 23,000,000 acre-feet as given in Table 7.  The
usable storage capacity has not been determined, but the limiting fac-
tor is poor water quality (84) .  Ground-water temperature generally
ranges from 50° to 80°F, but has been observed locally as high as
1826F.

Safe ground water yield for the entire North Lahontan Basin is esti-
mated to be 60,000 acre-feet.  There is no overdraft (5).

South Lahontan Basin
Most usable ground water in the predominantly mountainous South Lahon-
tan Basin occurs in scattered alluvium-filled valleys .  The alluvium
consists generally of lenticular beds of unconsolidated to semicon-
solidated clay, silt, sand, and gravel of cenozoic age.  The inter-
vening mountainous areas are underlain by consolidated sedimentary,
igneous, and metamorphic rocks, mainly of Mesozoic age or older.  These
rocks contain only small quantities of recoverable ground water and,
therefore, are not considered a major source of ground water.

In the South Lahontan Basin, 50 valley-fill areas have been identified
as significant sources of ground water.  The total area of the 50
valleys is more than 13,000 square miles.  The water-bearing deposits
range in thickness from 30 to about 2,000 feet.  Depending on local
conditions, recharge infiltrates at rates of less than 1-1/2 feet per
day to more than 10 feet per day in the upper part of alluvial fans

and in stream channels .  The maximum measured depth to water in the
water-bearing deposits is more than 975 feet.  In several valleys
there are flowing wells .

Total storage capacity of the 50 basins as shown in Table 8 is more
than 134,000,000 acre-feet.  The usable storage capacity has been
determined only for Indian Wells Valley where it amounts to 720,000
acre-feet (85).  Ground-water temperature generally ranges from 50
to 80°F, but has been observed locally as high as 137°P.

Safe ground-water yield for the entire South Lahontan Basin is esti-^
mated to be 300,000 acre-feet per year; an annual overdraft also esti-
mated to be 300,000 aere-feet exists (5).

Colorado Desert Basin
Most usable ground water in the Colorado Desert Basin occurs in
alluvium-filled valleys which occupy about half the basin.  The
alluvium consists generally of lenticular beds of unconsolidated clay,
silt, sand, and gravel of Cenozoic age.  The intervening mountainous
areas are underlain by consolidated sedimentary, igneous, and meta-
morphic rocks, mainly of Mesozoic age or older.  These rocks contain
only small quantities of recoverable ground water and, therefore, are
not considered a major source of ground water.

In the Colorado Desert Basin, 45 valley-fill areas have been identi-
fied as significant sources of ground water.  The total area of the
45 valleys is about 12,800 square miles.  The water-bearing deposits
range in thickness from about 48 to 2,800 feet.  Depending on local
conditions, recharge infiltrates at rates of less than 1-1/2 feet per
day to more than 10 feet per day in the upper part of alluvial fans
and in stream channels .  The maximum measured depth to water in the
water-bearing deposits is 644 feet.  In several valleys there are
flowing wells .

Water in storage (in 1965) in the 45 valleys totaled 158,000,000 acre-
feet and is given in more detail in Table 9 .  The usable storage capa-
city has been determined only for Coachella Valley, where it amounts
to 3,600,000 acre-feet.  Ground-water temperature generally ranges
from 60  to 90°F, but temperatures of more than 500°P have been ob-
served locally (36) .  The dissolved-solids content of the water varies
greatly, depending on local conditions .  Prior to importation of
Colorado River water, most water used in the Coachella Valley came
from ground water (87, 88) .

Safe ground-water yield for the entire Colorado Desert Basin is esti-
mated to be 100,000 acre-feet per year; an annual overdraft estimated
to be 200,000 acre-feet exists (5) .

NEVADA

Nevada, with an area of approximately 70.7 million acres is the seventh
largest state.  The average precipitation is less than any other state
and most of that occurs during the winter months.  Only about 6% of the
land is under cultivation and the high  altitude results in a wide daily
variation of temperatures.

In 1950, the water use in the state amounted to 1,600,000 acre-feet of
which 190,000 were from the ground-water.  By 1956 the total water use
had risen to 2,300,000 acre-feet of which 530,000 acre-feet came from
the ground-water supply.  The total average precipitation in the state
is 50 million acre-feet of which about  8% or 4 million acre-feet is
the average annual runoff.  About half  the runoff or 2 million acre-
feet end up recharging the ground-^water reservoirs of the state.  By
1962 there were 5 valleys which were overdrawing their annual supply
and several others were using practically all of their annual supply.

As the demand for water becomes more acute, the ground-water basins of
the state will be required to supply more and more of the state "s water
needs.  This is already evidenced by the increase from 190,000 acre-
feet per year in 1950 to 530,000 acre-feet per year in 1965.  This
represents an increase of about 180% in fifteen years, or 12% increase
per year based on the 1950 figure.

There are a number of problems associated with developing the ground-
water in Nevada.  The problems may be classified in a general way as
follows:   (1) Natural supply and distribution.  (2) Natural losses.
(3) Conservation and management.  (4) Water quality, and (5) Legal.

The natural ground-water yield approaches about 2 million acre-feet.
In addition to the perennial yield there are 200 million acre-feet in
storage in the upper 100 feet of the saturation zone .  One of the
problems in developing the stored ground-water, is the problem of
determining how far it is feasible to lower the ground-water table.
In some areas, the lowering of the ground-water would help control the
loss of water through phreatophytes .  If the ground-water table is
lowered excessively, the pumping costs  will rise thus increasing the
cost of water.  Most of the water-bearing formations consist of fine
water-bearing materials and it is difficult to develop a well which
will produce large quantities of flow.  The Sierra front and the
Humboldt River Basin have the best water supplies, while the southern
part of the state is very arid and already short of water in certain
areas .

There are approximately 3 million acres of phreatophytes in Nevada
which waste approximately 1-1/2 million acre-feet of water.  This is
a substantial portion of the potential  ground-water left to be develop-
ed in the state.  In order to put this  wasted water to beneficial
                                   41

-------
use, methods will have to be found to salvage this water which is now
being lost to evapotranspiration.  Eradication of phreatophytes also
poses the potential problem of increased erosion in some areas .

Many of the ground-water basins lie below closed basins with internal
drainage.  The resulting accumulation of salts over large areas has
contributed to the mineralization of the ground-water underlying some
two million acres in the state.  As a result of this mineralization,
development of ground-water may be severely restricted in many valleys
of the state.

The legal problems connected with ground-water development are numer-
ous and will continue to increase.  The infringement of water rights
is already a problem in many areas .  As the demand for water approaches
or exceeds the natural supply, the problem of preferential use among
dortestic, municipal, irrigation, and other uses will arise.  Since
some ground^water basins are interconnected geologically and there is
flow between basins, there will be problems of water rights and water
management that will have to be solved.  There are also a number of
ground-water basins which cross state boundaries, so as use of water
along boundaries increase, this problem will have to be resolved.

Nevada has been divided into 253 hydrographic areas which are essen-
tially valleys .  Each valley is partly filled with alluvium which is
the principal storage reservoir for ground-water.  These valleys have
become the basic social, economic and water development units in
Nevada.  Most boundary lines of hydrographic ridges have been inter-
preted from the most detailed topographic maps available in 1967.  The
size of the hydrographic areas range from 9 square miles to 2,182
square miles and the valley floor elevations range from 800 feet above
MSI, to 7,200 feet above mean sea level.  There are 82 small hydrograph-
ic areas (1-200 square miles), 151 median sized areas (201-1,000
square miles)  and 20 large areas (1,001-2,200 square miles) .  These
hydrographic areas are grouped into 14 hydrographic areas .  The large
scale unifying hydrographic features which were the general basis for
the areas fall into three broad categories:  (1) drainage basins of
large regional streams, (2) drainage basins that have no large regional
streams, and  (3) groups of mostly topographically closed valleys.  The
areas vary in size from 106 square miles to 46,783 square miles.  The
above areas have been combined into six hyclrologic basins as shown on
Figure 4.

Humboldt Basin
The average annual precipitation for this basin is 10 inches with an
estimated average runoff of 850,000 acre-feet.  Most of the valleys
in this basin are underlain by alluvial deposits which act as under-
ground reservoirs, that are recharged by water seeping down from the
surface.  The natural recharge in this region is estimated at 480,000
acre-feet.  Based on the 1965 use level, there is still about 390,000

acre feet of ground water which could be developed annually.  In addi-
tion to the natural ground water supply, water could be mined from the
upper 100 feet of the ground water reservoir.  It is estimated that
over a 50 year period, this basin could produce an annual ground-water
supply of 870,000 acre feet from the upper 100 feet of the storage
reservoir.  These figures indicate that there are over 1,000,000 acre
feet of water annually available for future development.

Central Lahontan Basin
The Central Lahontan Basin might be considered an arid region with an
average precipitation of only 8.4 inches.  The average annual runoff
of 110,000 acre feet is lower than any other area in Nevada.  The
average annual recharge to the ground water of 104,000 acre feet is
about the same as the surface runoff.  As of 1965 about half of the
annual yield was already being used and so the potential of a stable
ground water supply is not very large.  The upper 100 feet of the
ground water reservoir could be depleted at an average rate of about
320,000 acre feet per year for a 50 year period, but this would have
to be temporary and the annual cost of extraction would slowly rise as
a result of the falling water table.

Tonopah Basin

The average precipitation in this basin is about 9.5 inches per year.
The estimated runoff is on 290,000 acre feet and the annual average
recharge to the ground water is 680,000 acre feet.  The annual use in
1965 was about 200,000 acre feet frora the ground water leaving a future
development potential of about 480,000 acre feet.  Using an arbitrary
50 year period, the one-tins ground-water storage could be depleted at
an annual rate of 1,000,000 acre feet.  This means that an additional
ground-water supply of about 1,500,000 acre-feet could be developed
in this basin .

Lower Colorado River Basin
 In  1965, the ground-water puirpage in this part of Nevada was about
 115,000 acre feet.  However, the water is being pumped at a rate in
 excess of the replenishment rate so that the water table is falling.
 It  is estimated that the ground water storage to a depth of 1200 feet
 is  190 million acre feet so that the storage reserve is fairly large .
 The water supply development in this area is from the ground water and
 until there are new sources of water found, it seems that the one-
 time ground water storage reservoir will continue to be the main source
 of  water in this area.

 Great Salt Lake and Snake River Basins
Both of these basins are small and are low population regions so that
the ground water supply in these two areas is not considered to be very

UTAH

Utah has an area of 84,916 square miles and  an  average precipitation of
11.5 inches.  The precipitation varies from  5 inches or less in the
driest parts of the Great Basin to over 60 inches  on some of the high-
est peaks of the Wasatch Mountains.   The  average annual runoff is 0.25
inches or less in the driest parts to about  20  inches or inore in the
highest mountains .  Irrigation  is the major  water  user in the state and
Table 10 shows the various uses of water  in  the year 1960.

Of the  1,165,000  irrigated acres of land  in 19^0,  le^s  than half had ^i
adequate  water supply.  However, since  the  average annual  runoff is 8.2
rail lion acre  feet per year (15) , there  is still  room for developnent in
Utah.   In addition to the surface water supply,  there are  still many
areas where  the ground water has not been fully  developed  so Utah has
a reasonable  growth potential as far as her available ground water
supply  is concerned.  This potential is reflected  by the fact that in
1970 the  use  of ground water rose to a  total of  680,000 acre feet from
a total of 481 producing wells (89) . This  represents an increase .

The hydrologic basin boundaries  are shown on Figure 5.  About half the
state  (the western part), lies in the Great Basin  which is a closed
basin and is  rrenerally arid or semiarid as  far as  precipitation is
concerned.  The eastern half of the state lies principally in the
Colorado  River drainage basin.  The Wasatch Range  and the  High Plateaus
of Utah form a belt of high land running  down through the  state basical-
ly separating the Great Basin and the Colorado River Basin .  A very

srrall area in the northwest corner of the  state drains into the Snake
River Basin .

The principal supplies of  ground water are found in the alluvial fill
of the valleys of the Great Basin and in alluvium along a few streams
in the Colorado Plateaus .  Ground water is also found in the sedimen-
tary strata of the bedrock on the flanks of the Uinta Mountains in the
southeastern part of the Colorado Plateaus and in scattered areas
throughout the state .

Small quantities of ground water can be obtained from wells throughout
much of Utah, but large supplies that are of suitable chemical quality
for irrigation, public supply or industrial use, generally can be ob-
tained only in specific areas .  Only a few wells outside of these areas
yield large supplies of water of good chemical quality.

Less than 2 percent of the wells in Utah obtain water from consolidated
rocks.  The consolidated rocks that yield  the most water are lava flows
such as basalt, which contains openings enlarged by solution;  and sand-
stone, which contains interconnected openings between the grains that
form the rock .  Most of the wells that tap consolidated rocks are in
the eastern and southern parts of the state, in areas where water
supplies cannot be readily obtained from unconsolidated rocks .

tore than 98 percent of the wells in Utah draw water from unconsolidat-
ed rocks.  These rocks may consist of boulders, gravel, sand,  silt, or
clay, or a mixture of some or all of these sizes.  Wells obtain the
largest yields from the coarser materials  that are sorted into deposits
of equal grain size.  Most wells that tap  unconsolidated rocks are in
large intermountain basins, which have been partly filled with debris
from the adjacent mountains.

Upper Colorado River Basin

The rocks of the Upper Colorado Basin which is located in Utah consist
of eight major geologic groups  (11) based on general hydrologic proper-
ties,  tost of the Colorado Plateau is made up of outcrops of shale,
siltstone, fine grained sandstone, igneous and metamorphic rocks and
these formations do not make good aquifers which produce large capacity
wells .  Only about 4% of the area is covered, with exposed deposits of
unconsolidated materials and volcanic rock.  It is this relatively
small area which has the potential of producing good wells.  The ground
water storage in the upper 100 feet of aquifer is estimated at about
45 million acre feet with  only 7 million acre feet in the area of high
permeability.  No good estimate is available on the potential perennial
yield of the Utah part of  the Upper Colorado River Basin .

About 40 to 45 thousand acre feet of water are withdrawn from the
ground water each year in  this area.  The principle uses are for irri-
gation, public supplies, domestic and stock use, and industrial use.

                                  47

Great Basin

This basin covers most of the western section of the state of Utah.
tost of this basin is covered with unconsolidated deposits of alluvial
fill which is often very thick and highly porous,  The rest of the
area consists of various types of consolidated rocks which generally
have a low porosity .

No estimates are available for the perennial yield of this area but
some work has been done on evaluating the water in storage in the
Great Basin.  In the upper 100 feet of the ground-water reservoirs in
the Utah part of the Great Basin, there is 71,900,000 acre feet of
water stored (7) .  For development purposes, this would permit mining
the water at an annual rate of 1.4 million acre feet per year for 50
years .

The 1965 ground water withdrawal in the Great Basin of Utah was about
600,000 acre feet.  The yield of an average well was about 1,000
g.p.m., although the flows varied from 10 to 8,600 g.pjn.  Large capa-
city pumped wells account for the major part of the withdrawals .  It
seems that there is a great potential for the development of ground
water in Utah, especially in the Great Salt Lake area of the Great
Basin .

Lower Colorado River Basin
Only a small part of the Lower Colorado River Basin is in Utah and that
is  the Virgin River drainage basin .  Only small amounts of ground
water are used in this area and the amount available for future devel-
opment is extremely limited.  The ground water table is deeper than 500
feet in  about 80% of the area and only about 5% in the valley of the
Virgin River is  less than 200 feet from the surface of the ground.

Snake River Basin
Only  a very small area in Utah lies in the Snake River Basin.  Little
or no data are available for this area, but the area is so small that
it is believed that there are no significant ground-water supplies or
pollution problems in this area.

                               SECTION V

                   GROUND WATER POLLUTION  INDICATORS


Ground water is one of the most widely distributed resources of man and
one of the most important.   It is  subject  to natural and man-made pol-
lution and since  it is so valuable  to man's existence, everything pos-
sible should be done to preserve this resource.  In order to evaluate
the ground water  pollution problem, one must have some understanding of
the indicators which reflect a condition of pollution.  In addition to
a knowledge of the indicators, it  is necessary to understand something
about the critical concentrations of a given indicator which will begin
to make the water unfit for  certain beneficial uses.  It is also impor-
tant to know something about the processes which result in the pollu-
tion of the ground water by the various indicators.

Ground water pollution is generally determined by the presence of some
or many of the following indicators:

     1.  Chemical indicators -Total dissolved solids, chlorides,
     sulphates, calcium, manganese, fluorides, sodium, iron, boron,
     nitrates, phosphates, and others.

     2.  Biological indicators - Coliform  organisms, biochemical
     oxygen demand, viruses, bacteria, and etc.

     3.  Industrial indicators - pesticides, herbicides, acids,
     arsenic, heavy metals, detergents, phenols, gasoline, and
     many others .

The above list is only a partial one but it does demonstrate the exten-
siveness and the  complexity of the  ground-water pollution problem.  It
should also be pointed out here that many  of the pollution indicators
are principally a result of man's living habits and his activities,
while many of the same indicators get into the ground water through
natural processes not affected much by man and his activities.

A pollutant may be undesirable because of  it*s toxicity—such as
arsenic for humans and animals, boron for  agricultural crops—or be-
cause of a specific undesirable characteristic related to a specific
use—such as "hardness" in boiler waters or the laundry industry,  it
may be undesirable because of a specific pollutant, as mentioned above,
or because of the combined effect of a number of pollutants, such as
the effect of total dissolved solids in agricultural and other uses.
A pollutant may be objectionable in relation to one specific use yet
not for others.   Undetected pollutants may be present in any water,
since waters are  usually monitored and tested only for known or
suspected pollutants .

-------
In the region under study much of the area is arid or semiarid and the
soils are relatively high in many minerals, especially the chlorides,
sulphates and carbonates of potassium, calcium, magnesium, and sodium.
The soils are neutral or alkaline in reaction .  During the weathering
process large amounts of soluble salts may result from the parent rocks
Arid climates involve both low rainfall and humidity.  When the rain-
fall does come, evaporation is rapid and there is little leaching of
the soil.  As a result, the arid soils remain richer in many of the
mineral constituents than do soils in humid regions where leaching is
a regular process (15) .

Arid soils are also characterized by an accumulation of calcium car-
bonate at some point in the soil profile.  This zone of accumulation
of calcium carbonate is closely related to rainfall, both total amount
and seasonal distribution.  At some locations,  the calcium carbonate
accumulations become solidified causing hard layers which may limit
root penetration and impede drainage.  Salt accumulation is more severe
in the lower-lying areas of drainage basins because more water is
generally evaporated from the lower areas .  The higher concentrations
of salts in the arid soils tend to increase the potential of the
mineral pollution of the ground water which lies below.

The process of mineral accumulation in the soil is known as mineraliza-
tion.  It is usually associated with restricted drainage.

Sodium salts generally predominate in the early stages of mineraliza-
tion.  Calcium carbonate and calcium sulfate are less soluble so they
accumulate more slowly .  Alkalization takes place when the sodium ions
replace the cations previously adsorbed on the soil particles.  As the
percentage of exchangeable sodium is increased, the soil becomes more
alkaline in reaction.  Salinization deals mainly with, the total
dissolved salts while  alkalinization principally involves the amount
of exchangeable sodium present.

In the western states  there are many areas where salts have accumulated
in the soils so that large areas have become saline or alkaline in
nature.  When excessive rains or irrigation applications cause water
to flow down through those soils to the ground water basin below, some
of these high concentrations of salts are leached out and. carried into
the ground water reservoir.  Table 11 lists the extent of this type of
problem in eighteen states, and the four states included in the study
of this report are underlined.

Various standards of water quality are used depending upon the use of
the water.  Standards for irrigation, domestic and a number of indus-
trial uses have been formulated by various agencies (90, 91}  .  Details
of some of the standards applicable to various uses are presented in
the Appendix of this report.

 The  information presented in  the paragraphs which  follow represents a
 summary  of  measured pollution indicators  for which data are  available
 to us .   It 's  presentation here does  not imply  any  level of statistical
 significance  nor  any  degree of adequacy of the data in  a quantitative
 sense.   Rather, it  is intended to  give a  general indication  of  the
 pollutants  which  have been detected  and measured within the  study area,

                                Arizona
 There are  many measured indications of  ground  water pollution through-
 out the  entire state  of Arizona.  The most common of the  measured indi-
 cators,  (mineralization of the  ground water) is  found  in  all  of  the
.waters of  the  state.   The  type  of mineral, the amount,  and the time
 distribution vary considerably. There  is often  considerable  variation
 in the amount  of mineralization in waters from different  depths .  Dis-
 tribution  of high concentrations of total dissolved solids in the
 ground waters  of Arizona is shown in  Figure  6.  This figure indicates
 that there are a number of areas in Arizona  where the  mineralization
 os tiie ground  water exceeds 1000 mg/1.
                        I
 Hardness of water is  a problem  in many  areas in  Arizona.   Fluorides  in
 excessive  amounts are also found in many Arizona ground waters .   Ex-
 cessive hardness and.  fluorides  become a problem  when the  water is to
 be used for drinking  water.

 A discussion of measured indicators of  pollution in each  of the  hydro-
 logic basins of Arizona is presented  in the  paragraphs belc;vT.

 CENTRAL GTIA RIVER AND ADJOINING MEXICAN DRAINAGE

 Mineralization
 The ground waters of this  basin  are  among  the most heavily  used  in  t/.'i
 whole project area.  TLie Salt River  Valley is one of the major nydro-
 logic units in this basin  and its  nane  is  the result of the character
 of the water and soil.   Most of  the  ground water basins in  this
 drainage area are over-developed and yield water which is highly
 mineralized (17, 19, 92, 21). Serious  problems were recognized  more
 than twenty years ago by McDonald  (20) . Measurements of total dis-
 solved soilds show many wells yielding  water  in excess of 3000 p.p.m.
 The salt content of ground waters  is generally quite variable; with
 wells at the center of  heavy water using areas often showing highest
 concentrations of salts, and those near the outer edge maintaining  good
 quality.  Range of total dissolved solids  varies from about 200  (not
 many wells are this low in TD3)  to above 7000 p.p.m., and are very
 commonly between about  700 and 2000  p.p.m. The deeper aquifers  usually
 yield water of higher quality than the  shallow ones.  Ground water
 levels are declining and the concentration of total dissolved solids  is
 generally increasing throughout  the  basin. At many locations, the
 sodium content of the water is high.

                               53

-------
Fluoride

This basin has a fluoride problem, at many locations throughout the
basin.  The problem appears to be greatest in the south portions of the
basin, with a measurement of 9 p.p.m. being reported on the Papago
Indian Reservation by Heindl (93) .  Concentrations in excess of 1.5
p.p.m. are found at many locations throughout the basin.  As indicated
by the drinking water standards in Table A-2 these concentrations are
very hi gh.

Boron

Boron does not seem to be a great problem in this basin.  Concentra-
tions up  to about one part per million have been noted in the southern
part of the area.

Nitrate
Nitrate concentrations in excess of 100 p.p.m. are common in the Salt
River Valley, especially in the Phoenix metropolitan area; and in the
Upper Santa Cruz area near Tucson (94, 24, 27, 21).

Heavy Metals

Some indications of heavy metals in the ground water have been noted
in  the area of Phoenix and Tucson—zinc, chromium, and cadmium—but
the problem has apparently been solved.

UPPER GILA RIVER AND ADJOINING MEXICAN DRAINAGE

Mineral!zation
Mineralization of ground water in this basin is somewhat variable,
being high in the San Pedro, Willcox, and Safford sub-basins?  and
generally not so high in the others, many of which are not over-
developed from a ground water point of view.

Fluorides
Fluorides in ground water are above the recommended limit for domestic
water in many parts of this basin .

LOWER GILA RIVER BASIN
Min era! iz ati on

Ground waters in this basin are very highly mineralized.  In the Well-
ton-Mohawk area, ground waters are pumped for drainage purposes only,
and total dissolved solids run as high as 18,000 p.p.m.  In the Palo-
mas Plain, concentrations as high as 5000 p.p.m. have been measured.

                                  54

-------
Most waters have high sodium content.

Fluoride

Fluoride concentrations in excess of the recommended limit are found
at many locations .

Boron

Excessive concentrations of boron are found in this basin, especially
in the Dateland area.

Lithium

Several samples of water in the Dateland-Hyder area contained excessive
lithium, according to Weist (70).

COLORADO RIVER BASIN
Most of the  ground water potential in this basin is located along the
lower main stem of the  river,  in the alluvial material.  This basin, as
arbitrarily  designated  for this report  also includes some lands of the
Colorado Plateau  in  northern Arizona, and considerable desert area
which drains into the Colorado River.   Because of these wide differ-
ences in the area included in  this basin, the quality of ground water
also varies  considerably.

Mineralization
Although  there  are many wells  in  the Yuma area which yield good quality
water,  there  are  also  many which  have total dissolved solids content
from 1000 to  5000 p.p.m.  In the  Ranegrass Plain, the waters generally
have fairly high  total dissolved  solids—up to about 4000 p.p.m.  In
the Big Sandy Valley  (95) the  waters are generally of good quality,
but some  of the shallow waters are quite saline.  Water in the King-
man area  is generally  good, with  maximum TDS of 750 having been
me as ure d.

Fluoride
High concentrations  of  fluoride have been noted in the Ranegrass Plain
and Big Sandy Valley.

LITTLE COLORADO RIVER BASIN

Mineralization

The waters  of this basin  come  mainly from the  sandstone between the
Itogollon Rim and the Little  Colorado River.  These waters are of good
quality near the Mogollon Rira  but  increase in  salinty as they move

                                   55

-------
toward the river.  At some locations the total dissolved solids are as
high as 70-0 p.p.m., and the water must be diluted with river water
before it can be used for irrigation.

                             California
There is considerable variation in ground water quality in the state of
California.  Quality deterioration through the accumulation of salts of
various kinds must rank as the most important of all of the pollution
factors.  Many other indicators of pollution have been noted at various
locations throughout the state.  Distribution of high concentrations of
total dissolved solids in the ground waters of California is shown in
Figure 7.  A detailed discussion of each of the nine hydrologic basins
of the state follows.  Data and general information in this portion of
the report are taken mainly from reports of the Water Resources Coun-
cil, the U.S. Geological Survey, and various reports of the California
Department of Water Resources (5, 6, 77, 96)  and others specifically
cited in the following paragraphs.

NOR1H COASTAL BASIN
This basin is the only portion of the entire area covered by this re-
port which does not have an arid climate .  The climatic effects on
natural mineral accumulations in the ground water described above are
evident here, and the extent of mineralization is limited in most
parts of this basin.  The basin is sparsely populated,  and the man-
made pollution is also quite limited.

Mineralization
The mean annual precipitation in most parts of this basin is more than
40 inches.  The soils of the basin have, therefore, been subjected to
leaching action over a long period and much natural-occurring salt
has been washed from them.  Where natural drainage exists, the ground
waters are of generally high quality.  Even in this basin some miner-
als are present in excessive amounts at some locations .  At several
locations along the coast (near Eureka)  ground water pumpage has
caused sea water intrusion into the fresh water aquifers .  in the
northeastern part of this basin near the Oregon border, the climate
is arid and ground water deterioration exists in several small areas
in the Klamath River drainage .  There are scattered locations of ex-
cessive total dissolved solids, boron, iron, and manganese.  Limited
measured data are available»•  Summaries of some measured data are
presented in Table 12 .  Ground water mineralization in selected areas
is discussed below.

In Scott River Valley,  the ground water is generally magnesium or
calcium bicarbonate in type, moderately to very hard, meets chemical
standards for drinking water and is generally suitable for irrigation .

In the Eureka Plain, the ground water is bicarbonate in type with
magnesium the predominant cation .  The water is moderately hard and
generally of good chemical quality suitable for most beneficial uses.
In a few wells, the boron content is sufficiently high that the water
is unsuitable for irrigation of most crops .

In the Eel River Valley, ground water is generally magnesium-sodium
bicarbonate in type, of good chemical quality suitable for most uses.
Higher mineral content is found near the Eel River estuary.  Ground
water in the Mad River Valley  is moderately to very hard, and high
chloride and total dissolved solids content along the coast gives
evidence of sea water intrusion.

In Shasta River Valley and some of the upstream closed basins show
total dissolved solids at some locations so high as to render the water
unsuitable for various uses.

Iron

In the Smith River Plain, iron concentrations in excess of 0.3 mg/1 (the
limit for drinking water recommended by the U.S. Public Health Service)
are found throughout the area. In the Mad Fiver Valley, a high total
iron concentration occurs throughout the valley.  In Round Valley, the
high iron concentrations render untreated water objectionable for
domestic use.

SAN FRANCISCO BAY BASIN
This  basin  is  a  fast  growing metropolitan area which has experienced
intensive ground water development.   Ground water is used for municipal,
industrial  and agricultural purposes.  In areas immediately bordering
the Bay, extremely high salt concentrations are found.  The major
metropolitan areas now import  their water from great distances—mostly
from  the Sacramento,  Mokelumne and Tuolumne River Basins.  Much of the
imported water is  used to re-charge the aquifers being used as a
ground water supply in the San Francisco Bay Basin, in an effort to
"repel" the sea  water intrusion which appears to be the major cause of
the high salinity.

Mineralization
A summary of  available  1965 measurements of mineral pollutants in ground
water in a number of  the  sub-basins draining into San Francisco Bay is
shown in Table  13.

The mineral quality of  the native  ground water of this basin is
generally fairly  good,  except  in areas where the ground water has been
degraded by salt  water  intrusions. The water in this basin is quite
variable in hardness,, being soft in some locations and very hard in
others .

In the Livermore Valley the ground water at some locations has become
so highly mineralized that the state has established controls on saline
discharges.  A water softener business has moved out of the valley be-
cause it can no longer dispose of the regeneration water in the valley.
Hone-regenerated units are also being phased out (97) .  This is the
result of the fact that there is no ground water leaving tie valley
at any time and wastes such as these degrade the ground waters, al-
ready high in total dissolved solids, even further.

Extremely high concentrations of dissolved solids have been recorded
in Pataluma Valley, undoubtedly caused by sea water intrusions.

Nitrates
Excessive  concentrations of nitrate have been measured in the Liver-
more Valley according  to Dirker  (97) .  Some wells in the Santa Clara
Valley also indicate nitrate content in excess of 45 p.p.m. (S8) .  It
is presumed that other ground waters in this area also contain high
concentrations of nitrate, especially since there are extensive urban
areas and  sewage and refuse disposal areas in this region, but no
records of such concentrations are available to us.

CENTRAL COASTAL BASIN

Surface drainage of this basin is quite limted.  Because of the
limited elevation of the mountains of these drainages, many of the
surface streams are intermittent.  None are snow-fed, and water
supplies are very limited much of the time .  As a result, the ground
water supplies are generally preferred both for municipal and agricul-
tural purposes .  The ground water has been severely over-developed,
as was pointed out in  the previous chapter, and much of the surface
water is used to re-charge the ground water aquifers.  Several reser-
voirs on the surface streams of  the basin  function primarily for flood
control and for temporary storage of waters which are used to replenish
the ground water supplies.  Approximately  90% of the water needs of
this basin are met by  ground water.  Quality of the water varies
greatly.

Mineralization
High concentrations  of  salt  have  shown  up in a number of walls particu-
larly  in  the Santa Ynez River Valley and in the inland Carrizo Area
in the southern part of the  basin.  A summary of 1965 observations of
some mineral constituents  in the  ground water is shown in Table 14 .

In the Pajaro  River  sub-basin  (99) there are many instances of wells
showing chlorides in excess  of  5000 p.p.m.  The sane is true for some
of the J coastal areas in San  Luis  Obispo County, with total dissolved
solids also proportionately  high  (100,  101) .  Investigations in the
Santa Maria River Valley (102,  103), in the Upper Salinas Basin (104) ,

-------
the Carinel River Basin  (105) , and  in  the Lompoc Basin  (106) all report
mineralization and other water  qtiality problems.

Nitrates

Some excessive nitrates have been  measured at many locations in this
basin.  More than 230 samples from about 100 different wells have
shown nitrate concentrations in excess of 45 p.pan.  (107) .  Much of
the nitrate moves with  the soil moisture to the ground water as
reported by Stout, et al  (108) .

Boron

Boron is not a great problem in this  basin, with anounts toxic to
agricultural plants only showing in a limited number of wells.

Fluoride
Very few  samples of ground water indicate fluoride concentrations
in excess of the minimum  recommended values.

Other Pollutants
Ground water  in  the San Lorenzo River Watershed has been reported
(109) to have a  high  iron  content,  This basin has a considerable
amount of oil production.   The activities associated with drilling
and production of oil entail  the handling of brines and waste oil.
Undoubtedly there are instances of pollution from these sources, but
the regulatory agencies maintain careful monitoring of these activities
ilo published  reports  of measured pollutants from these sources are
available to  us .

SOUTH COASTAL BASIN
The ground water in  this  basin  is subject to heavy use and re-use.
This basin includes  the Los Angeles and San Diego metropolitan areas.
The area is heavily  dependent upon ground water supplies to supplement
the imported water .  Water is imported fron the Colorado River and the
Owens Valley  (in the South Lahontan Basin) .  When the California
Aqueduct is completed, water will also be imported from the Sacramento
Basin.

Mineralization
The accumulation of dissolved minerals in the ground water is one of
the greatest problems of  this basin.  This basin is already subjected
to nore water quality management  than any other part of the project
area.  Ground water replenishment has been practiced in this basin for
many years, and at the present  there are several fresh water "barriers"
created by injection underground  of water, relatively free of dissolved

                                   63

-------
minerals, to serve as a barrier against sea water intrusion.  Much of
the water used for the barrier is storm drainage or domestic, indus-
trial or agricultural waste water which has already been through the
use cycle one or more times and may, itself, have a relatively high
salt content.  This exemplifies the problem which faces much of this
basin, since the ground water is progressively accumulating more and
more dissolved minerals.  Mineral quality is quite variable throughout
this basin.  Near the ocean, many wells contain extremely high concen-
trations of dissolved solids, especially chlorides.  A summary of
minerals at selected locations as of 1965 is shown in Table 15 .  Many
waters are extremely hard, as will be seen from the table .  It should
be noted that the information in the table represents measurements
from many locations and is the result of an extensive monitoring system,
This basin has probably been studied more thoroughly than any other
part of the project area.  Problems of mineralization are very critical
in this Lasin.  See  (110) (111) .

In the Santa Ana River Basin, the salt balance problems have been
investigated quite thoroughly  (112, 113, 114, 115) .  The limited ground
water resources of the coastal plain south of the Santa Ana River Basin
have been overdeveloped in several areas and the water quality has
declined in a number of locations (116, 117, 118, 119, 120, 121, 122,
123,  124, 125, 12S).  Severe deterioration of water in Ventura County
was evident as early as 1956  (127) .

Boron

Excessive concentrations of boron exist at a number of locations
throughout this basin .  In some areas a nigh boron content is found
near  the coast, whereas in others, it is found in the inland valleys.
It is a special problem in the Riverside-San Bernardino area.  This
area has in the past been a heavy producer of citrus fruit.  Citrus
is very sensitive to boron--sorne agricultural experts indicate that
concentrations of 0.5 p.p.m. are toxic to some citrus varieties.  Boron
concentrations are increasing  in the Riverside and other areas (128),
and citrus production has decreased in recent years, partly due to
the boron content of the water.  Concentrations in excess of 0.5 p .p .m.
exist at many localities.

Nitrates
Throughout this basin there are scattered instances of excessive nitro-
gen in ground water.  Quite a number of samples indicate nitrates  in
excess of 45 p.p.m.  However, it is not believed to be a general prob-
lem, in any of the sub-basins, but rather a localised problem associated
with a particular well at a particular time .  In some areas of heavily
fertilized agricultural land, as for example on some Riverside citrus
land, quite high nitrates have been found moving into the ground water
(129) .

Fluorides

Fluoride concentrations in excess of one part per million have been
found at a few scattered locations throughout this basin .  Fluoride
in ground water is not a Eiajor problem in this basin.

Gasoline
In September, 1968, gasoline was detected in at well at Forest Lawn
Memorial Gardens in Los Angeles .  Drilling and other tests conf irmed
that the gasoline pollution area was quite widespread and threatened
many wells in the area  (130) .  Details of investigation into the
causes, and of the remedial action taken is given in the next section
of this report.

Others
There are undoubtedly other pollutants in ground water of this basin .
The waters of this basin are heavily used and re-used with much water
being injected underground to increase the ground water supply,  thder
these conditions, the addition of pollutants is quite possible.
However, no reports of other pollutants are available to us.  Minerali-
zation is a great problem, and far over-shadows the others .

SAM JOAQUIN BASIN

This is a large basin with an arid climate.  The southern portion of
the basin—the Tulare sub-basin—has very limited drainage to the.-north
in most years.  As a result, the mineralization of the ground is in-
creasing with time.  Imported water from the Feather River project,
being of higher quality, may decrease the rate of degradation.  Pre-
sent and future expected drainage from the valley floor lands under
irrigation is and will be of such poor quality that the water resource
plans for the valley include a "master drain" to convey the drainage
water from the valley, thus limiting the flow of drainage waters into
the San Joaquin River.  Ground waters of this basin show considerable
fluctuation in quality, with the poorer quality resulting during times
of drouth when the quantity of water is decreased.

Mineralization

The total dissolved solids in the ground water exceed the maximum per-
missible limits for many uses at various times at many locations
throughout this large valley.  Extreme hardness is a problem at many
locations .  High chlorides and total dissolved solids have been noted
in the oil field areas north of Bakersfield near the Kem River.  Ex-
cessive sodium content of the ground water is a problem in some areas .
When the sodium is in exchangeable form it often presents a particular
problem in irrigation and drainage of agricultural lands as described
previously.  A summary of limited information on tine minerals in

                                  66

-------
this basin as of 1965 is shown in  Table  16 .

It may be noted from the tabulated data  that water in  the Salt Slough-
Los Banos Creek area has a rather  high total dissolved solids content.
Saline water from wells in the Stockton  area was reported in 1955
(131) .                                             ^

Deep  in the alluvium of the San  Joaquin  Valley  there are bodies of
highly saline old marine waters, referred to by some as connate waters.
Not many wells go into this salty  water,  but the U.S.  Geological Survey
is preparing a report outlining  the base of the fresh  water in the
valley.  This report is expected to be available late  in 1971 or early
in 1972.

Boron

Boron is a problem  at many locations  in  the San Joaquin Valley.  Drain-
age water from the  agricultural  lands in the west side of the valley
often contain as much as 10 to 15  p.p.m. of boron.  There is also a
boron problem on the east side of  the valley near Bakersfield.  The
boron problem is usually greatest  in  waters derived from or associated
with  the coastal range of mountains (132) .

Nitrates
The  San Joaquin Valley is  heavily fertilized.   It  is a rich agricul-
tural area,  but the  drainage waters,  especially on the west side of
the  valley,  are highly mineralized and often contain high boron as
mentioned  above.  These waters  also contain high nitrate concentra-
tions .  Most of these pollutants percolate  with the water into the
deeper ground water  aquifers of the valley, and thus have considerable
effect on  the water  quality. According to  Pratt (129), the nitrogen
is not tied  up in  the soil (by  nitrification)  except in the surface
organic layer.  The  nitrates move into the  ground  water along with
other dissolved constituents.  Heavy nitrate concentrations have
shown up in  the area around Fresno.  Done en (133)  reported on presence
and  movement of nitrates into the ground waters .  High nitrate con-
centrations  have been reported  in the Fresno area  (134, 135) and in
the  Delano area (136) .

Arsenic
In a relatively small area west of  Fresno,  arsenic has been found in
the ground water in  an amount up to ten  times the limit recommended by
the U.S. Public Health Service.  Lofgren (137)  believes that the
arsenic in this area was  forced out of deep clays compressed by the
action of land  subsidence in this particular area.  A considerable
subsidence problem does exist at this location.  lofgren has been
involved in  studies  of the land subsidence  here for many years .

Other Pollutants

In tne San Joaquin Valley  there  are  extensive  agricultural enterprises .
Many of tae crops are heavily dusted or  sprayed with  various pesti-
cides .  One big problem associated with  dusting and spraying is tne
disposal of the pesticide  containers . This  causes a  potential hazard
because of the concentrated materials used and if containers are not
carefully disposed of,  the pesticide residue  is sometimes a serious
problem, according to Cornahan (138) . Some  sewage spraying in the
Hokelunr.e River drainage by small  connunities  poses a potential problem
which is not  serious  (139) .

SACRAMENTO BASIL!
Ground water  in  this  basin  is generally  of excellent  quality and suit-
able  for most uses.  This basin is  a heavy water producing area, pro-
viding a great excess of water that is wasted in the  San Francisco Bay.
Most  areas  have  ample water supplies for the present  and future, and
the waters  have  not been degraded by extensive over-use as has been
the case in many areas. However, the total use of ground water in this
basin does  exceed the "safe yield*', and  there are areas of local short-
ages  and diminishing  water  quality.

Mineralization
 Tne  dissolved solids content of the waters  of this  basin  generally is
 less than 500 p.p.m.,  but there are locations where total salts nave
 been recorded at over 2700 p.p.m.  The predominant  water  type  is cal-
 cium bicarbonate, but sodium and i?agnesiura  are present in significant
 quantities at some locations .  A summary of rdnersls in the  ground
 water at selected locations as of 1965 is given in  Table  17.

 Boron

 Boron is moderately high in sore areas in this basin.  Measurements as
 high as 13 p .p .m. have been recorded.  This is many tir-ies more tnan the
 toxic limit for most plants .

 nitrates
 There are no serious nitrate problems in this basin,  according to
 Carnahan (138) .  Localized problems may exist at some locations, de-
 pending on sewage and solid waste disposal practices  and other condi-
 tions .

 NORTH LAHONTM 3 AS IK

 Ground water in this basin is not developed extensively.  The basin it-
 self is small, as already previously described.  Only three ground
 water sub-basics are recognised (1) Surprise Valley (near Cedarville in

Min e ral iz ati on

Ground water in this basin is of generally good quality.  The water
contains excessive sodium at a number of locations .  Water ranges from
soft to very hard depending on location.  A nmber of mineralized hot
springs exist in the Bridgeport area.  Summary of a limited number of
measurements of mineral quality are given in Table IS.

Boron

Boron in excess of 2 p.p.m. occurs  at a number of locations in all
three ground water areas.

Fluoride

Fluoride in excess of  the U.S. Public Health Service recommended Unit
is found at a number of  locations in this basin.

Nitrates
Nitrates in excess  of  45 p.p.m.  are found in some wells in Honey Lake
Valley.

Arsenic
Increasing  arsenic  concentrations have been found, in a number of wells
(6) .  State  and  County Health  Departments have conducted a survey to
determine the  extent  of  arsenic degradation.

SOUTH LAHCHTAN BASIN
•This basin is  relatively  small, but highly arid.  In a, general sense
the ground water of this  basin is good, but there are many wells which
exhibit poor quality characteristics.

Mineralization

The mineral quality of ground waters in this basin is quite variable.
A total of 120 wells in the Antelope Valley Hydrologic Thit and 79
wells in  the Mojave Hydrologic Chit were sampled in 1965.  A summary of
the results of mineral analysis of these samples is shown in Table 19.
Most wells have water of  reasonably good quality, but a number have
undesirable characteristics  (140, 141) .  Near the town of Boron, the
quality is poor with total dissolved solids in excess of the limit for
drinking  water.  Sodium concentrations are also excessive in a number
of wells .

Boron

A number of wells in the  basin have boron  concentrations above 2 p.p.m
including most of the wells in the vicinity of the town of Boron.

Fluoride

Fluoride in excess of the  limit  for drinking water is found in a number
of wells in the basin.

Arseni c

Excessive amounts of arsenic have been reported in some wells.  In the
North Muroc basin, wells  along the north edge of the basin penetrate
aquifers in which naturally-occurring arsenic if found.  The U.S.
Public Health Service has  a recommended upper limit of 0.01 mg/1 of
arsenic in public water supplies and a maximum allowable of 0.05 mg/1.
In the vicinity of Edward's Air  Force Base a detailed study of arsenic
content of waters in this  area  (142) showed that from 32 samples of
surface drainage water, all except two exceeded 0.1 mg/1, with the
highest concentration being 20 mg/1 and many over 1.0 mg/1.  Wells in
the area have a high potential hazard related to the arsenic.

Other Pollutants
In June, 1970, a detailed study of  ground water quality in the vicinity
of Barstow was completed (143, 87}.  This study indicated that a number
of wells were polluted with detergents, phenols, hexavalent chrome,
phosphate and ammonia nitrogen showing up in a number of samples taken.

COLORADO DESERT BASIN

This basin includes three ground water sub-basins.  The most signifi-
cant is the Coachella Valley  (known  as Whitewater Hydrologic Unit),  the
Dale Hydrologic Unit (the vicinity  of the community of Twentynine Pains),
and the Lucerne Valley, just  east of Victorville—most of the develop-
ment is in the Coachella Valley.

Mineralization
A summary of sampling  in 1965 for mineral quality of the ground water
is shown in Table 20.  Water in  the Coachella Valley is quite good
quality, but in the Lucerne Valley  (a  "sink" area) three wells of 22
sampled showed a highly mineralized sodium chloride water.  Other wells
in the valley are generally suitable for irrigation and drinking water.
Water in the Dale Unit is generally good, but two wells indicated high
mineralization, and also a high  sodium content.

Boron

In the Lucerne Valley and  the  Dale area several wells yielded water
with boron in excess of 2  parts per million .

In the Dale  area, one well had excessive fluoride.

                               Nevada

The principal problem with ground water pollution in Nevada is minerali-
zation of the ground water.  Many of the ground water basins are closed
basins so that evaporation tends to cause  soluble salts to accumulate
at the ground surface where  recharge waters carry the dissolved salts
into the groundwater reservoir.  The ground water extracted near the
center of the closed basins  is often rather highly mineralized.  The
total area underlain by ground water exceeding 1000 mg/1 of dissolved
salts is shown in Figure 8.  This area very likely exceeds 2 million
acres having a specific yield  or a drainable volume of 15%.  The total
volume of mineralized water, exceeding 1000 mg/1 of dissolved solids
in the first 100 feet of the ground water  reservoir is a total of 300
million acre feet of water in  the state of Nevada (15) .

Nevada can conveniently be divided into six hydrologic basins (Figure
4) which are as follows:   (1)  Humboldt  (29,900 sq. mi.)  which covers
the northern part of the state, had a population of 27,600 in 1965.
(2) Central  Lahontan  (9,800  sq. mi.) which covers the Truckee River
Basin and the West  Central section of the  state, had a. population of
166,400 in 1965.   (3) Tonopah  (44,300 sq.  mi.) which covers the central
and the south central portion  of the state, had 8,300 people in 1965.
(4) Nevada has a portion of the Lower Colorado River  (17,100 sq. mi.)
in the southeast corner of the state.  Part of the Great Salt Lake
Basin  (4,200 sq. mi.) and  the  Snake River  Basin  (5,100 sq. mi.)  are in
Nevada.  These basins are  shown on Figure  4.

Most of the  253 ground water basins are small closed valleys in alluvi-
al deposits  in the  valley.  The ground water quality in these valleys
range from fresh to very saline as explained at the beginning of the
section on mineralization.  There are only two places in the state
where the total dissolved  solids in the ground water exceed 10,000
mg/1, and these are small  point sources in the Tonopah Basin in Soda
Spring Valley and Clayton  Valley a few miles south and east of Walker
Lake.  One spring runs about 15,000 rag/1 and the otner is almost
30,000 mg/1  but both are just  seepage flows that probably do not have
a significant effect on the  local ground water.

In some areas the amount of  total dissolved solids may not be the
limiting pollutant  for water use.  There may be excessive quantities

                                  75

-------
of a single element or compound which  may be  the limiting factor for
water use.  For example,  such elements or compounds as boron, fluoride,
manganese, iron, sulfate, nitrate,  chloride,  and others are sometimes
toxic at very small concentrations  so  a critical amount of any one of
these may be a limiting  factor on the  use of  the water.  There are
several local areas in the  region where the presence of one of these
toxic elements or  compounds is the  limiting factor on the use and
development of the ground-^water supply .

The suitability of water for irrigation may be evaluated on the basis
of salinity hazard, sodium  (alkali)  hazard, and the concentration of
bicarbonate, boron, and  other ions. The salinity hazard depends on
the total dissolved solids  and is normally measured in terras of elec-
trical  conductivity with units of micromhos per centimeter.  Nearly
all irrigation waters, which can be usad for  any length of time, have
conductivity values of less than 2250  micromhos per centimeter.  The
sodium  (alkali) hazard is expressed by the sodium-absorption ratio
 (SAR) and it represents  the relationship between the cations of sodium
and the  cations of calcium  and magnesium.  If the proportion of sodium
among the cations  is  high,  the  alkali  hazard  is high but if calcium
and magnesium predominate,  the  alkali  hazard  is low.  M SAR in excess
of 10 will  generally  represent  a sodium hazard, in fine grained soils .

In the  case of  the bicarbonate  ion, the measure of a hazardous level
of concentration is  given by the residual sodium carbonate (RSC).

   ESC  =  (CO--  -f- HCOj)     -    (Ca++   +  Kg"1"1")  in which concen-
                                                  .trations are ex-
                                                  pressed as equiva-
                                                  lents per million .

If the  residual sodium  carbonate  (RSC)  is greater than 2.5 epm  (equiva-
lents per million),  the  water is not suitable for irrigation.  Most
natural waters  contain boron and, boron is essential to the growth of
all plants  but  the quantity required is very  small.  In general,
boron in excess of 3  mg/1 (milligrams  per liter) is injurious to most
crops,  and  much smaller  amounts may be toxic  to certain crops.

There are two areas  of high population concentration in Nevada, the
Reno-Carson City area and the Las Vegas area. Municipal wastes are
used  to charge  the ground water in  the Las Vegas area but there are no
indications in  either of the areas  of  ooliform pollution of the ground
water.   There have not been any organic pollution problems in the
 ground  water so far  in the  state although there are some potential
problems in the highly populated, areas .

Nevada  is not a very  highly industrialized state but there is some
industry and it makes a  major contribution to the economy of the state .
Thero have  been no indications  so far  that there is any problem, with
pollution of  ground water from  industrial wastes.  Neither pesticides

                                  77

-------
nor commercial fertilisers have been a problem anywhere in the state.

The atomic testing in Nevada has been dona in the Tonopah Basin which
is very sparsely populated.  Ho indicators of nuclear pollution have
been measured in the ground water in that part of the state so it is
felt that so far the atomic testing has not created any ground water
pollution problems.

In summary, there are many areas in Nevada where the ground-water is
not very satisfactory for domestic use or for irrigation.  The limiting
condition may be one or a combination of the factors discussed in the
previous paragraphs so that in order to develop the ground-water
supplies in many valleys of Nevada, solutions must first be found to
the numerous problems of mineralization.  With this general summary of
the mineralization problems in Nevada, the following sections will
give a more detailed description of the mineralization problems as
they exist in each of the six hydrologic basins in Nevada.

HUMBOLDT BASIN
Ground water in the principal aquifers in most basins in the Humboldt
basin is fresh and in many places contains less than 500 mg/1 of
dissolved solids .  Notable exceptions are the Smoke CreeJc,  Desert
Creek, and Black Rock Deserts in the lower Quinn River basin and the
Lovelock area in the lower Humboldt River basin, where water from most
aquifers is saline.  In these areas, the dissolved-solids content of
the water ranges from about 1,000 mg/1 near the margins of  the valleys
to more than 3,000 mg/1 in the central portions .  Stagnation in sedi-
mentary deposits containing large amounts of soluble salts  is the
principal reason for the high mineral content of the ground water, but
evapotranspiration and recycling of irrigation water also raise the
mineral content of the water in stallow aquifers .  The waters are
mostly sodium bicarbonate and sodium chloride in type and locally con-
tain moderate to large amounts of fluoride and boron among the minor
constituents .  Fresh ground water probably occurs at the very edges
of the desert areas near the mouths of some of the larger streams .

The principal aquifers in several other valleys in the Humboldt basin
contain saline water, at least locally.  For example, two wells in the
northern part of Pine Valley produced water containing nearly 4,000
mg/1 of dissolved solids from depths of about 400 feet.  There appears
to have been no outlet from Pine Valley during the Tertiary Epoch and
the sediments tapped by the wells apparently contain soluble salts.
Similar conditions may also exist in Huntington Valley, although water
from two wells in the valley is fresh.  In the southern part of Duck
Lake Valley near the south ends of the Kings River and Quinn River
valleys, and the north end of Grass Valley, some aquifers locally con-
tain slightly saline water.  Although the ground water in Desert and
Silver State Valleys is fresh, the dissolved-sol ids content of the
water in most places apparently exceeds 500 mg/1; near the lower ends

                                  78

-------
of the valley, it may  exceed  1,000 rag/1  in  some aquifers.  Also, the
boron and fluoride  content of ground water  from several sources in
Desert Valley is relatively high.

Another area of high mineralization is located in San Emidio and the
Smoke Creek Deserts  (144) .  These areas  are  located just north of
Pyramid Lake.  Of twelve wells tested in this area in 1966, most of the
samples indicated high salinity and alkalinity hazards .  The results
varied over a rather wide range but it appears that much of the ground
water in this area  is  of poor quality for agricultural purposes,  in
summary, the San  Emidio Valley, the Smoke  Creek Valley, the Lower
Humboldt River Valley,  and Pine Valley probably contain over 90% of
the slightly saline  (1000 to  3000 mg/1)  and moderately saline (3000 to
10,000 mg/1) ground water in  the Humboldt Basin.  In turn, this region
contains in the upper  100 feet of the ground-water reservoir about
25% to 30% of the mineralized ground water  supply in the state.  This
is approximately 3  or  9 million acre feet of ground water with a
dissolved salt content exceeding 1000 mg/1.

CENTRAL L AH ONTAN BASIN

Most of the saline  ground water in this  basin is found in the Carson
Sink area.  The dissolved-so lids content of the water in this area
ranges from 1000 mg/1  to well over 3000  mg/1 including large amounts of
sodium, chloride, sulfate, and bicarbonate  and relatively large con-
centrations of the  toxic ions such as boron, fluoride, and arsenic.

The Walker Lake area has ground water exceeding 1000 mg/1 of dissolved
solids in many parts of the Walker Paver Valley but most of the ground
water in that valley is classified as fresh water.  The mineralized
watar generally comes  from the shallow wells and the deeper aquifers
contain good water.

There is also another  area of saline ground water located due east of
Pyramid Lake about  10  miles or so.  The  salt concentrations in this
area run from 1000  to  above 3000 mg/1 and the area involved is around
30,000 acres.

These three areas of Carson Sink, Walker Lake, and east of Pyramid Lake
contain about 50% to 60% of all the mineralized ground water (> 1000
mg/1) in the entire state of  Nevada.  There  are in this region about
1,^200,000 acres of  land underlain by ground water with dissolved salt
concentrations exceeding 1000 mg/1.

In order to develop the ground water potential of this subregion, re-
search will be required to find users who can tolerate high salt con-
centrations or to develop an  economical  means of treating the water.

The western side of this '
-------
at restricted locations in the region.  Eagle and Washoe Valleys
generally contain ground water with less than 500 mg/1 of dissolved
solids in the ground water .

TONOPAH BASIN

Ground water in principal aquifers in most valleys in the Tonopah
Basin is fresh, and in many valleys, the water contains less than 500
mg/1 of dissolved solids.  In the Clayton-Fish Lake Valley areas south
of Tonopah, much of the ground water is moderately to very saline as
is most of the water in the lower part of the Amargosa Desert.

Jiany of the valleys in the Tonopah Basin are topographically closed,
and therefore, water in the shallow aquifers beneath the mudflats or
playas at the lower ends of these valleys probably is saline .  Deeper
aquifers in the lower parts of most of these topographically closed
valleys, however, probably contain fresh water.  One known exception
is in the lower parts of Steptoe Valley, where the deeper fill deposits
may contain large amounts of soluble salts .

Ground water in the northeastern part of the Tonopah Basin, where car-
bonate rocks predominate, is generally of a calcium magnesium bicar-
bonate type.  In the southern and southwestern parts of the basin,
where tuffaceous volcanic rocks predominate, the water is mostly sodium
bicarbonate, sodium chloride, or mixed type.

The ground water in many of the valleys in the southern part of the
Tonopah Basin contains relatively large concentrations of fluoride,
which apparently are derived from the volcanic rocks in this part of
the region.  Relatively large concentrations (one to 13 mg/1)  of
fluoride occur in parts of the Amargosa Desert, the Sarcobatus Flat-
Oasis Valley areas, Gabbs Valley, and Pish Lake Valley.

GREAT SALT LAKE BASIN
Only a small part of this basin lies in Nevada and most of the ground
water is fresh.  There are some small areas just north of Wendover,
Utah, where the salt concentrations exceed 1000 ng/1.  The area is
located on the western edge of the Great Salt Lake Desert in a very
sparsely populated region .

LOWER COLORADO RIVER BASIN
The major part of the ground water in this area has less than 1000 mg/1
so that it is classified as fresh water.  There are a few thousand
acres north of Lake Mead that are underlain by mineralized waters
ranging from 1000 to 3000 mg/1.  Some of these ground waters are saline
because the natural aquifers contain large amounts of soluble salts.
The ground water table averaged a decrease in elevation of 10 feet per
year from 1960 to 1965 in the Las Vegas area.  The water is being mined

                                   80

-------
but the degeneration of ground water quality is not yet very severe in
this bas in.

SNAKE _SIVEP_BAS IN

Tnis area in Nevada is very sparsely populated and the average elevation
is over 5000 feet above mean sea level.  Cenozoic volcanic and sedimen-
tary rocks occupy about 85% of the total area.  Most of the rocks have
a rather limited capacity to transmit water.  In the upper 100 feet of
saturated rock, the ground water storage exceeds 15 million acre feet.
Much of tiie water, however, could, not be recovered economically and in
areas it may not be chemically suited for many uses.  Although the
water quality data for this area are very limited most of the well
samples available indicate that the water is generally within the
following ranges (145) :

     Salinity Hazard  - low to medium

     Sodium Absorption Ratio - 0.1 to 2.0 with most samples below 1.0.

     Sodium Hazard -- All samples low.

     Total  Dissolved Solids - 45 to 205 ro.g/1.

The toxic ion concentrations are also very low so that most of the
ground water in this  area appears to be of relatively high quality for
most uses.

                                 Utah

Ihe ground water in Utah is generally of fairly hioh quality and in
many areas  it has not been used, very extensively.  Legal restraints in
the past have made it difficult to develop the ground water resources
in Utah,   t*itil 1959, Utah Courts generally held that the owner of a
discharging well was  liable for damages resulting in serious reduction
of water level, artesian head, or discharge in wells with earlier
water rights.  Tha effect of this policy was to limit the development
of the ground-water resources.  In 1969, however, the Utah Supreme
Court reversed a lover court decision in the following way:

     "there has come to be recognized what may be referred to as
     the  'rule of reasonableness1 in the allocation of rights in
     the use of underground water.  This involves an analysis of
     the total situation:  the quantity of water available, the
     average annual recharge in the basin, the existing rights
     and their priorities.  All users are required where necessary
     to employ reasonable and efficient means in taking their own
     waters in relation to others to the end that wastage of
     water is avoided and that the greatest amount of available
     water is put to beneficial use."
                                   81

-------
          In a specific reference to the maintenance of natural
     artesian pressure, the court also stated:  "We perceive no-
     thing in our statutory law *** which compels a conclusion
     that owners of rights to use underground water have any
     absolute right to pressure."  (146)

This decision should help open up the development of ground water in
Utah.  The optimum development of the total water resources can occur
only under unified or correlated management between surface and ground-
water supplies.

In developing Utah ground-water resources, the principal water quality
problem is the mineralization of the ground water.  The mineralization
problem is rather extensive (Figure 9),  but it is not as severe as in
other states of this region because the poor quality water underlies
desert or mountainous areas where the population is very low.

The mineralization of ground water in Utah is generally the result of
the following factors:  (1) Solution from natural rocks, (2)  Highly
mineralized waters leaking into aquifers from fault zones, (3)  Agri-
cultural waste waters including irrigation return flows, (4)  Evapo-
transpiration, and, (5) a few other miscellaneous processes.  The
ground water quality in the areas of high use is generally very good.
The large area west of Salt Lake City of poor quality shown on Figure
9 is a desert area of the state where there is little or no popula-
tion .  The other area of poor ground water quality is on the Colorado
Plateau where the ground water supply is very limited.

UPPER COLORADO RIVER BASIN
Most of the ground water in this basin has a total dissolved solids
concentration of less than 1000 mg/1.  However, there are extensive
areas in the Price, San Rafael and the Dirty Devil River basins where
the total dissolved solids in the ground water exceeds 1000 mg/1.
Most of the low quality ground water is found in Emery and Grand
counties of Utah.  One rather extensive area of poor ground-water
quality is also found in Uintah County as shown in Figure 9.

Except for the Dirty Devil River basin, the sodium-adsorption ratio is
between 5 and 10 for all of the above areas of high total dissolved
solids.

The present use of ground water in this region is very small and the
present effects of pollution are minor.  However, the ground-water
does represent an important future resource and much needs to be
learned about this resource before it can be developed and managed

which contains large quantities of fresh ground water.  In the Bear
River Basin in the north end of the Great Basin, the major part of the
ground water contains less than 1000 mg/1 total solids.  In the upper
part of the Bear River basin the ground water is of the calcium mag-
nesium bicarbonate type, whereas most of the ground water in the lower
basin is of the sodium chloride or sodium bicarbonate type.

There are a few local areas in the Bear River basin where the ground
water is slightly or moderately saline.  -The main factors affecting
the poor quality in some of these areas are probably the following:
stagnation of water in fine grained deposits containing soluble salts,
evapotranspiration, recharge with saline irrigation return flow and
lateral movement of water into aquifers from areas of large thermal
springs .

Nearly all of the ground water in the mountain valley east of Great
Salt Lake and Utah Lake is fresh.  Most principal aquifers to the
east of Great Salt Lake and the Tooele and Jordan valleys contain
fresh water.  The ground water basin west of Great Salt Lake is highly
mineralized with salt concentrations exceeding 3000 mg/1 in many parts
of this area.  The ground water basin along the borders of the north
end of Great Salt Lake is also highly mineralized.  The lower end of
the Sevier River basin contains large areas underlain by ground water
of poor quality (1000 mg/1 or more)  .  This area of the Great Salt
Lake Desert and the Sevier Desert covers an area of roughly 5 million
acres and most of the ground water exceeds total dissolved salt con-
centrations of 1000 mg/1 .  It is estimated that over 2 million of
those 5 million acres are underlain by ground water exceeding salt
concentrations of 3000 mg/1 .  The ground water in most of this area
has a high sodium content with sodium adsorption ratios exceeding 10.
This means that much of the ground water in the area west of the
Great Salt Lake is of questionable quality for most irrigation uses.
Not many ions, which are often considered to be toxic, have been
identified in this area.  However, in the upper and middle Sevier
River basin, the fluoride content exceeds three milligrams per liter
and is as high as six mg/1.  These relatively large concentrations of
fluoride are probably derived from rocks of volcanic origin which
underlie much of this basin .

LOWER COLORADO RIVER BASIN
This area in Utah covers about 3000 sq. miles.  The ground water in
the area is almost all high quality with a salt content of less than
1000 mg/1 .  There are no significant pollution problems in the ground
water in this area.

In summary of the mineralization problems in Utah, there are large
areas in the state where the ground water has a salt concentration of
over 1000 mg/1.  Most of these problem conditions exist in areas of
very low rainfall, limited population, and limited quantities of
                                   84

ground water. ' If this water  is ever  to be  used  for  beneficial pur-
poses, economical means  of  desalinization will have  to be developed.
Many of the water quality problems  are located in  areas where the land
is not very suitable  for growing  things and so it  is likely that any
development in many of these  places might have to  be for industrial
purposes.  In connection with the mineralization problem, most of the
dissolved solids consist of the  following ions or  groups of ions
(calcium, magnesiim,  sodium plus  potassium,  chloride, bicarbonate and
sulfate) .  In the areas  surrounding the Great Salt Lake and especially
on the west side of the  lake, there are many areas where the ground
water is saline.  All the  valleys that drain directly into Great Salt
Lake and the Great Salt  Lake  Desert contain saline ground water at
their lower ends.  In a  number of these valleys  the  total dissolved
solids increase markedly with depth.  For example, in Sink Valley on
the edge of the Great Salt  Lake  Desert, the ground water has a con-
centration of total dissolved solids  of about 3600 mg/1 at a depth of
225 feet.  This increases to  49,000 mg/1  at a depth  of 675 feet.  The
west  side of Great Salt  Lake  and most of  the Great Salt Lake Dasert
have  ground water which  exceeds  3000  mg/1.   This area is probably the
only  area in the state which  has  large quantities  of poor quality
ground water.   The toxic ions such as boron, fluoride, heavy metals,
and others are  not known to be a problem  anywhere  in the ground water
of the state.   Pesticides  are not known to  be a  problem and neither
are the  nitrates  and  phosphates.   Although  BOD and coliform organisms
are potential problems in  a number of places,  these  pollutants are
filtered out  rather  effectively  as  the water passes  through the soil.
Therefore, organic  and biological pollutants are not known to be a
serious  problem anywhere in the ground waters of Utah.  If they are
problems,  there have  not been adequate  measurements  made to determine
their extent.

                             SECTION VI

              CONDITIONS CAUSING GROUND WATER POLLUTION


In the previous section, the measured indicators of ground water pollu-
tion were discussed, and the indicators found in each of the  sub-
basins of the project area were summarized.  No attempt was made to
signify the cause of the pollution, but only to register the  fact  that
some degree of pollution does exist.

During the course of the investigation being reported herein,  many
existing and potential causes of pollution of the ground water were
made known to us.  Often water of poor quality is caused by several
factors—even a combination of a number of physical conditions.  Indeed,
in many instances, an existent pollution condition may have several
contributing sources.  In this section, various conditions, circum-
stances or activities which have had a known or suspected polluting
effect on ground waters are listed.  The following list is a  fairly
good summary of most of the conditions which cause pollution  of  ground
water.  They are listed approximately in the order of their signifi-
cance as causes of ground-water pollution in the project area:

     1.  Natural leaching
     2.  Irrigation return flow
     3.  Sea water encroachment
     4.  Solid wastes
     5.  Disposal of oil field brines and other materials
     6 .  Animal wastes
     7.  Accidental spills of hazardous materials
     8.  Water from fault zones and volcanic origin
     9.  Evapo-transpiration of native vegetation
    10.  Injection wells for waste disposal
    11.  Fertilization of agricultural lands
    12.  Land disposal of wastes—municipal and industrial
    13.  Seepage of polluted surface waters
    14.  Urban runoff
    15.  Connate water withdrawal
    16.  Mining activities
    17.  Aquifer interchange
    18.  Mineralization from soluble aquifers
    19.  Crop residues and dead animals
    20.  Pesticide residues
    21.  Land subsidence effects on water quality
    22.  Other causes

Each of the above processes is a potential cause of ground water pollu-
tion in the four states of the project area.  In many instances  it is
difficult or impossible to positively identify a given act or set  of
acts or circumstances as the cause of a given known pollution.  Never-
theless, the following discussion of each of the causes listed above

                                  87

-------
is presented to assist in the development of a better  -understanding  of
the factors which cause pollution of ground water.  In most instances
we also list the location or locations where these  actions or  condi-
tions are known or suspected to have a polluting effect on the  ground
water.

                          Natural Leaching

Throughout the project area, irost of the ground and surface waters
contain some natural dissolved salts.  These dissolved salts have  their
origin in the soils and rocks of the watershed areas.  The presence  of
these minerals in the soil  and rocks is directly related  to the  cli-
mate as has already been explained.  The natural accumulation  of these
minerals is greatest in the areas of low precipitation, and especially
those areas where natural drainage is restricted.   Precipitation per-
colating through the salt laden soils, and rocks takes some of  the  salt
into solution and carries it into the ground water.  In areas  where  the
ground water is near the land surface; evaporation  and transpiration
of the ground water, which  leaves the salt on the surface, further con-
centrates the salt in the waters which are left behind.

Natural leaching may also take place within a water bearing aquifer.
Often the water, as it moves through an aquifer, dissolves soluble
minerals from the aquifer material itself or from its  confining  forma-
tions.  Natural leaching causes degradation of the  ground water in all
parts of the study area.  It is most intensified in the areas  of lowest
precipitation where the soil contains high concentrations of dissolved
minerals—especially the desert portions of the project area where
natural drainage is restricted and heavy accumulations of salt are
fornd in the soil.  In the  Great Salt Lake Desert,  for example,  waters
percolating through the salty soil have resulted in ground waters  high
in salts .  In the mountainous portions of the study area  the greater
quantities of precipitation leach salts out of the  soil,  but in smaller
quantities.  The greater quantities of precipitation  also tend to
dilute the salty waters so  that the salt content in many  locations near
the mountains is not excessive.

The usual ground water pollution problems related to natural leaching
involve the more common salts found in soil and water, especially  in
the arid regions.  There are locations, however, where  a  particularly
toxic element occurs naturally and gets into the ground water.  Exam-
ples are the boron at many  locations in the project area, and  the
arsenic in Kern County, California  (138, 142) .

                       Irrigation  Return Flow

In the arid west where irrigation  is necessary  for  growing crops,  the
salt content of the ground  water has been increased by irrigation  prac-
tices.  Much of the water  applied  to the soil  is  evaporated by the sun
thus leaving the dissolved  minerals on or near the  surface of  the  land.

                                   88

-------
Unless excess water is  applied to the  land,  these minerals  will  accumu-
late in the soil  and will  inhibit the  growth of plants.   For this  rea-
son, irrigated lands must  be  flushed out occassionally by excessive
applications of water to the  land.  This is  usually automatically  ac-
complished in normal irrigation practice because of the  difficulty of
distributing the  irrigation water at an efficiency of greater than
about 50%, (unless the  irrigation water is  applied by sprinkling —
Israelsen and co-workers found an average of 38% efficiency on selected
Utah farms (147)) .  The surplus irrigation water applied seeps into
the soil and often passes  down into the ground-water reservoir.  It
leaches the accumulated salts out of the soil and carries them into the
ground water, thereby building up the  salt  concentration in the ground
water.  In addition to  the natural salts in  the soil,  there are often
nitrate and phosphate fertilizers applied to the soil so that some of
these substances  are also  carried into the  ground water.  Nitrates,
especially, become a problem  in some areas.   It should be noted that a
large part of the irrigation  return flow finds its way into the ground
water.  Irrigation return  flow has many pollutional effects on ground
water.  For a comprehensive treatise on this subject the reader is
referred to the work of the Utah State University Foundation (90) .

Many engineers and scientists have reported  research and observations
related to this subject—Scofield (148) , Wilcox and Resch (149) ,
Fuhriman  (150, Thorne and  Peterson (151), Reeve and Fireman (152),
Bouwer  (153) , Israelsen and Hansen (154) , Bower et al (155) , and others.
Undoubtedly a large portion of the minerals  pollution found in the
ground waters of  the project  area is caused  by irrigation return flow.
Degradation of ground water on a broad scale is evident  in  the drainage
waters of the San Joaquin  Basin in California where a proposal has been
made to construct a fresh  water canal  from  the Sacramento River to
bring dilution water to the San Joaquin Basin as a means of diminishing
the effect of the degraded drainage water collected in the San Joaquin
River (156) .

                        Sea Water Encroachment
In California,  there  are  262  ground water basins  which  contain water
bearing deposits open to  the  ocean  or to saline inland  bays  (157) .  In
many of these basins  over-development of ground water at a number of
locations in California has  caused  the sea water  to  encroach  into the
fresh water areas.  These conditions usually  have developed in the
alluvial plain  of various rivers  draining into the ocean,  especially
when intensive  development of the ground water supplies has occurred.
The Water Resources Council  (6)  reports that  areas of sea water  intru-
sion have developed in  the flood plains of the Eel,  Mad,  and  Russian
Rivers north of San Francisco;  throughout the San Francisco Bay  area,
in the Salinas  River  flood plain  bordering Monterrey Bay,  and in all
heavily developed coastal areas along the California Coastline—San
Luis Obispo, Santa Barbara, Ventura, Oxnard,  Los  Angeles,  Long Beach,
Santa Ana, Oceanside, LaJolla,  and  San Diego. There have  been instances
                                   89

-------
of sea water encroachment into the rich Sacramento Delta, partly  from
surface streams and partly from ground water.  Begulations governing
the control of the Sacramento River include the provision that  about
4000 second feet of water must flow continuously from the Sacramento
River Channel into the upper reaches of San Francisco Bay to assist in
repelling the salt water.  Extensive studies have been conducted  re-
lated to the problem of sea water encroachment.  The California Depart-
ment of Water Resources (157) reports that the most serious intrusion
has occurred in the following areas (Figure 10) .

     1.  The West Coast Basin of Los Angeles County
     2.  The East Coastal Plain Pressure Area of Orange County
     3.  Petaluma Valley in Sonoma County
     4.  Napa-Sonoma Valley in Napa and Sonoma County
     5.  Santa Clara Valley in the San Francisco Bay area
     6.  Pajaro Valley in Monterey and Santa Cruz Counties
     7.  Salinas Valley area in Monterey County
     8.  Oxnard Plain Basin in Ventura County
     9.  Mission Basin in San Diego County

There are detailed studies in a number of the areas of most serious
encroachment (158, 159, 160) as well as some laboratory and theoretical
analyses of the problem and possible counter-measures (161) .  Various
water using agencies in California have established programs to re-
verse the movement of sea water encroachment.  For example, in  the Los
Angeles area, three "barriers" have been developed against the  sea
water encroachment.  The barrier is established by injecting non-saline
water at a line of injection wells whose axis roughly parallels the
ocean source.  The theory of the barrier is that by injecting the
water, the hydraulic gradient is reversed, so that flow is toward the
sea water source instead of away from it.  At some locations saline
water is also pumped from the seaward side of the barrier to assist in
developing the seaward gradient.  Alves and Hunt (162) in the 5th
Annual Report of the Alamitos Barrier Project, reported the completion
of additional injection wells but a landward movement of salt water
still existed despite injection of 5530 acre feet of fresh water  and
extraction of 1823 acre feet of salty water seaward of the barrier.
Mcllwain, Pitts, and Evans  (163) reported on the West Coast Barrier,
located near the coast between Torrance and El Segundo for the  period
1967-69.  Severty-seven thousand acre feet of filtered Colorado River
water was injected in the barrier area.  Injection at this barrier
began in 1953.  Effectiveness varies with depth and location, but
generally, the pumpage on the landward side of the barrier has  resulted
in an increase in the landward gradient.  However, chloride ion concen-
trations at certain points show a decrease and indicate that no intru-
sion is occurring in the northern half of the Barrier in  deeper
aquifer.  In the southern half of the Barrier, there  are  evidences of
continued intrusion in the deeper (San Pedro)  aquifer.  There were  also
signs of over-injection in the shallow sand aquifer.  In  the intermedi-
ate (Silverado) aquifer there were signs of general improvement.

Problems of "clogging" of injection wells are considered to be serious
and have required considerable expenditure of funds to "re-develop" the
wells—a process similar to development by bailing, cleaning, and
surging.  The causes and cures of clogging are not definitely known,
but it has been learned that filtration of water is usually necessary
before injection (164) .  Bookman and Edmiston (165, 166)  report on
general problems of management of the ground water in the Los Angeles
Area, including the extensive replenishment program.

The third barrier, known as the Dominguez Gap Barrier, has only recent-
ly been established to control sea water intrusion in the San Pedro
Bay area, between the Alamitos and West Coast Barrier.  The Dominguez
Gap Barrier was scheduled to begin operation in 1971, and the effect
of this barrier is not known at the time of this writing.

In addition to the barrier projects, it should be noted that water has
been added to the ground water by "spreading" for many years in Cali-
fornia,  Michelson (167), reported that spreading began in 1896 on
Santiago Creek and in 1900 on the Santa Ana River.  Volk (168) re-
ported that up to 1933 a total of $227,000 had been expended on the
Santa Ana River spreading ground and that 266,784 acre feet of water
had been spread.  Land (169) reported on various methods of getting
water into the ground, and Freeman (170) , Mackel (171) , Sonderegger
(172), and Hill and Whitman (173)  all reported on various practices
and operational problems in the water spreading program at various
locations in California.  These early programs were intended to pro-
vide underground storage for water.  Only after the over-pumping of
more recent times have the  "water barrier" methods been used to pre-
vent intrusion of sea water in coastal areas .

In the Salt Lake Valley of Utah, the Great Salt Lake, (with a salt
content of over 200,000 mg/1)  is underlain by relatively impermeable
lakebed deposits.  According to Marsell (174) these deposits form an
effective barrier against the movement of these highly saline waters
into any of the important ground water aquifers .  There is some local
opinion linking the lake to some of the saline ground water in the
valley, but the authors do not believe that this is very likely.  The
possibility does exist, however, that the hydrostatic pressures from
the mountain-fed fresh water aquifers act as a shield to keep the salt
waters from entering the fresh water aquifers in appreciable amounts
if any aquifer connections to the Great Salt Lake should exist.  Ground
waters west of the lake are more highly mineralized than those on the
east, which are also nearer to the pressurized mountain sources.  It
may be that these saline waters west of the lake involve encroachment
of highly mineralized water from this large inland sea.

                            Solid Wastes
In the past, solid wastes were disposed of by burning or surface
dumping but these procedures have been replaced by sanitary landfill
                                  92

-------
operations .  The  solid wastes  are  dumped into  an  excavated  area  and
then covered over.  Normally the wastes  are  deposited  above the  ground-
water table and precautions are taken to seal  off the  wastes from the
ground water.  This procedure  generally  prevents  the  leaching of
pollutants from the solid wastes and carrying  them on  into  the ground
water.  However,  the potential for pollution is  always present.

When water seeps  down through  a refuse dump, the  leaching process  often
produces an increase  in  some of the following  pollutants  or conditions:
hardness, total dissolved solids,  calcium, magnesium,  B.O.D., acidity,
alkalinity (175) .  The gases of CO2 and  CH4  are  also often  generated.
As the leachates  filter  into the earth below the  waste material  -they
undergo a purification so that if  the ground water is  far enough away
from the waste material,  the pollution potential  is significantly  de-
creased.

The landfill operations  in Arizona are not  causing ground water  pollu-
tion problems of  any  known significance.  Generally the water table is
deep and the rainfall is small so  the effect of  landfills is not a
problem in this state.   Nevada's situation  is  very similar  to that of
Arizona and refuse disposal by landfill  is  not a recognized problem.

Only 67 of the 712 dumps in California are  classified  as  sanitary
landfills while  125 are  considered to be modified sanitary  landfills.
However, these are the larger  dumps and  they handle 90% of  the solid
wastes of  the state.  At 33 dump sites there is  direct discharge to
surface waters .   Eighty-one sites  in the state are apparently close to
or in contact with the local ground water.   There are  207 of the sites
with inadequate  control  of surface drainage  (6) .   It is likely that
some of these conditions are resulting in some ground  water pollution
problems,  at least the pollution potential is  there.

In California, standards have  been set for landfill operations.  The
standards  are simple  and easy  to work with  and so they are  listed here:

Classes of Dumps
     1.  A dump  in an area where there can  be  no leaching either to
         the surface  or  to the ground water.  This class  dump will
         take any type  of refuse including highly toxic materials.

     2.  A dump where  the natural  conditions are  such  that  the area
         can be made  to  prevent direct runoff  to  streams  or leaching
         into the ground water.   This type  of  dump can handle all
         refuse  except highly  toxic wastes.

     3.  A dump where the site cannot be protected from either the
         ground water or the surface water.  Refuse in this type of
         dump is  limited to non-toxic, non  putrescible materials
         such as  building material wastes,  old concrete slabs,
         asphalt  paving  debris, and etc.

                                   93

-------
There are a few areas in California where sanitary landfills are pro-
bably a threat to the ground water quality (138) .  The alluvial sedi-
ments of the Sacramento and the San Joaquin Valleys make these areas a
little vulnerable to landfills.  The extent of the pollution of ground
water is not very well known but it is considered to be a. potential
hazard.  Some areas have required some type of seal to separate the
waste disposal area from the ground water.

One of the problems of landfills is the generation of the gases CO2
and CH4.  The gases disperse into the soil and if they get to the
ground'water, the CO- might increase the corrosive ability of the water
by increasing its acxdity.  If the pH of the water is near neutral and
calcium or magnesium are present, bicarbonates may be formed to in-
crease the temporary hardness of the water.  The 014 is light and would
normally rise so that it generally will not have any deleterious effect
on the ground water.  Often chlorides will be leached out of the
landfill dumps and carried into the ground water.  In California, sani-
tary landfills are generally not known to be polluting the ground
water on a significant scale, although they still pose a pollution po-
tential .

In Utah, most of the solid wastes are being put in landfill dumps.
However, there are some areas which have not been very well designed.
The dumps for Provo, Salt Lake City, and Logan are in the lowlands
where the ground water table is fairly high.  These three refuse dumps
handle the solid wastes for over 250,000 people.  It is likely that at
certain times of the year, the ground water is actually near the refuse
disposal area.  The nearness of the solid wastes to the ground water
means that the potential for ground water pollution in these areas is
very large.  However, no information is available on the influence
these dumps are having on the ground water quality in those areas.  In
other parts of the state, the refuse dumps are generally in areas
where the water table is low and the wastes are isolated from the
ground water.  Many of the areas are still surface dumps that might
pose problems of surface water pollution but not ground water pollution.

          Disposal of Oil Field Brines and Other Materials
The production of crude oil is always accompanied by waste water pro-
duction.  The waste water produced is usually a highly saline brine.
Disposal of the brine is usually handled by one of three methods:

     1.  Re-injection underground
     2.  Discharge to the ocean
     3.  Discharge to a sump for percolation or evaporation

Each of these methods of disposal has a potential for water pollution.
In addition to the problem of disposal of brine, there is also a pro-
blem with some waste oil mixed with the waste water.  Recommended
practice includes careful skimming of the waste to remove the oil

                                  94

-------
before disposal of the water.

In disposing of the water by injection, extreme  care must be exercised
to prevent the brine from getting into  a fresh water aquifer.  Disposal
to the ocean presents little hazard to  the ground water supply as long
as the disposal pipe is maintained in good order.  Disposal from a
sump by percolation should only be used if-precautions are taken to
prevent the percolating brine  from entering into the ground water
supply.  Collins  (176) enumerates a number of ways in which oil field
practices can  cause pollution.  In addition to brine and waste oil
disposal problems, he cites pollution hazards associated with the
common oil field practice of using acid to increase the formation per-
meability.  Aside from the pollution by the acid itself, the practice
also often corrodes the casing  causing  inter-exchange between aquifers.

There is extensive oil and gas production at many locations within the
project area.  Wherever oil production  takes place there is a constant
danger of ground water pollution.  However, officials in the areas of
greatest oil and gas development,  (128, 138, 177, 178, 179, 180)  indi-
cate that the  industry is being inspected and no known problems of
ground water pollution exist related to disposal of oil field wastes.
The authors believe it is quite possible that undetected ground water
pollution is occurring in oil  fields within the  project area.

                            Animal Wastes
 During the past  two  decades,  the  increase  in  demand for beef and poultry
 has  resulted in  a trend for confined feeding  of livestock and concen-
 trated production of poultry.  The nunber  of  cattle on feed for
 slaughter in 1967 was 11 million  head,  an  increase of 120% in the past
 15 years.  In the major poultry producing  regions, 50% to 80% of the
 laying hens  and  most of the broilers are raised in confinement.  In
 California there was an 87% increase in cattle marketings between 1957
 and  1963.  Virtually all that growth was associated with an increased
 number of feedlots handling 10,000 head or more.  This trend is con-
 tinuing  at the present and is expected  to  continue in the future (181).

 Livestock on American farms produce  about  2 billion tons of manure each
 year.  This  tremendous production of animal wastes has resulted in a
 large  waste  disposal problem.  The animal  waste problem has already
 resulted in  the  pollution of many surface  water supplies and it has
 contaminated some ground water  supplies.   Studies have shown that the
 movement of  pollutants down through  the soil  from unpaved feedlots is
 minimal.  (182) .  Nitrates moved  the most rapidly through the soil pro-
 file.  However,  these tests were  limited in scope and feedlots on a
 more porous  soil might cause serious pollution problems to the ground
 water  below.  Barnyards and feedlots have  been cited as sources of
 excessive nitrate-nitrogen in shallow wells in Nebraska and Illinois
 (181) .
                                   95

-------
Sometimes the animal wastes are spread out on the land as a means of
disposal.  The amount of waste material that the land can handle with-
out causing a ground water pollution problem has not been determined
yet.  to estimate has been made that there are about 17.3 billion
pounds of nitrogen produced in a year by the farm animals such as hogs,
cattle, and chickens.  The disposal problem connected with these wastes
is a large one and such large waste production produces a high poten-
tial for the pollution of the ground water supplies.

Contaminants attenuate to harmless or innocuous levels at certain
distances from a waste site by mechanisms of decay, sorption, and
dillution (152) .

Some agricultural wastes decay or degrade more rapidly than others
depending on the presence or absence of oxygen, other wastes, or other
materials while other wastes persist indefinitely.  The survival of
bacteria and viruses is not well known, but the survival of many is
thought to be relatively short away from their nourishing environment.
In general, biological contaminants decay more rapidly in contact with
air.

Some pollutants such as phosphates move slowly or scarcely at all be-
cause they are sorbed by or react chemically with the earth materials.
Because of ion exchange or some other mechanism, clays tend to retain
many contaminants better than do sands.

Dilution is another process which tends to disperse the contaminants.
This process is inadequate, however, under many conditions.

Nitrates and biological contamination are in general the most adverse
pollutants of animal wastes .  Nitrates in excess of 45 mg/1 have been
known to cause methemoglobinemia in babies (blue babies)  and they are
often toxic to livestock,  Shortly after cattle and sheep drank high
nitrate water, 3100 ewes and 300 cows experienced abortions in one
operation reported by Wadleigh (183).  In one study of the nitrate
content in 6000 rural water supplies in Missouri, Smith (184)  con-
cluded that infiltrates from feed lots were the main source of nitrates
in the ground water.

A review of biological contamination of ground water by Mailman and
Mark (185) cites a number of examples in which bacteria and viruses
have moved from several inches up to 800 feet.  Eliassen and others
(186)  mde calculations to determine the bacterial movement in a large
number of soils.

Animal wastes sometimes produce other adverse effects on ground water.
These may be caused by organic compounds requiring oxygen for degrada-
tion;  from materials that cause color, taste, and odor problems; from
feed additives, cleaning materials and pest control chemicals which in
addition to being pollutants, may affect the attenuation of other
                                  96

materials;  from  addition of salts;  from changes  in the pfi of the ground
water; and  from,  plugging of the  aquifer.

ARIZONA

The livestock in Arizona were  estimated as  683,000 cattle, 46,000 hogs,
and 1,100,000 chickens  in  1967.   The  animal wastes from these sources
were estimated to have  produced  149,000 tons of  B.O.D., 48,500 tons of
nitrogen, and 15,000  tons  of phosphorous.   Most  of the livestock in the
state  are scattered out on the range  so only those animals concentrated
in feed lots or  poultry ranches  were  considered  as potential pollution
problems.   In 1967  the  state had 112  cattle feed lots of the following
sizes:  72  lots  with  500 to 2,999 animals,  28 lots with 3,000 to 9,999
animals and 12 lots with 10,000  to  50,000  animals.  In that same year
the poultry ranches were 84 poultry ranches with 50 ranches of 300 to
4,999  chickens,  21  ranches of  5,000 to 29,999 chickens, and 13 ranches
of 30,000 to  100,000  chickens.  The hog feed lots numbered 32 with 15
lots  of 200 to 499  hogs, 8 lots  of 500 to  999 hogs and 9 lots of 1,000
to 10,000 hogs  (10) .
                               \
Nationally  the major  cause of  pollution from feed  lots is stream runoff
from  the  lots.   Because of low annual precipitation in Arizona, the
surface runoff is small and the  seepage water is also low.  The soil
removes most  of  the oxygen demanding  wastes and  the soluble phosphates
are  absorbed  by  the soil.   Some  of the nitrogen  in the form of soluble
nitrates  might  leach  down  to the ground water.  The overall effect will
depend principally on the  nature and  the permeability of the subsoil
and  the depth to the  water table.

Although  animal  wastes  are a potential source of ground water pollu-
tion  in Arizona, they are  not  the cause of any known major pollution
problems  at the  present time.

CALIFORNIA

In 1968,  the  beef cattle plus  the dairy cattle numbered almost
1,900,000 head.   Although  most of the cattle were  fed on the open
range, there  were 453 feed lots  in operation. The poultry population
was  about 260 million and  many of those were concentrated in over
4,000 poultry ranches.   The hog  population was about 150,000 head.  The
estimated wastes per  year  resulting from the confined animals totaled
the  following (6) :

                 Solid Wastes      23,000,000 tons/yr.
                 BOD                  810,000 tons/yr.
                 Nitrogen              220,000 tons/yr.
                 Phosphorous           44,000 tons/yr.

Most  of these wastes  are spread  back  on the land for agricultural pur-
poses and these  wastes  seldom  cause any pollution problem in the ground

                                   97

-------
water.  Prom this study, it also appears that in the immediate vicinity
of the feed lots there are no known ground water pollution problems .
It is still true that all feed lots pose a pollution potential and so
areas near large feed lots should be monitored occasionally to make
sure that the ground water is not being polluted.

NEVADA

In 1965, Nevada had a little over 500,000 head of cattle (8).   About
20% of these cattle were being fed in feed lots.  The other livestock
included 5,000 hogs, 33,000 chickens and 200,000 sheep.  The wastes
from the feed lots were as follows:

                     24,000 tons of BOD
                      8,300 tons of Nitrogen
                      2,600 tons of phosphorous

Most of the animals were out on the land but these wastes from the feed
lots were also put back on the land.  There is no indication in Nevada
that animal wastes are creating a ground water pollution problem.  With
the low average rainfall in Nevada of about 9 inches, the ground water
pollution potential from animal wastes is not very high.

UTAH
The 1965 livestock population of Utah was estimated at the following
figures (12)"

                       Cattle          800,000
                       Hogs             40,000
                       Chickens      1,100,000
                       Sheep           900,000

The animal wastes from the livestock in confinement average 54,000
tons of BOD, 16,000 tons of nitrogen, and 5,400 tons of phosphorous.
In Utah there seem to be a number of places where animal wastes create
a surface water pollution problem, but they do not seem to be any more
than just a potential pollution threat to the ground water.

In summary, the animal waste problem has not been studied extensively
in the area of this present inventory, and so it is not generally rec-
ognized as an active source of ground water pollution.  Probably less
than 20% of the cattle in this area are confined in feed lots, but
feed lots are increasing in number and the animal wastes may become a
significant source of ground water pollution in the years ahead.

              Accidental Spills of Hazardous Materials

Accidental spills of liquid wastes, toxic liquids, gasoline, or oil
sometimes pose a serious pollution hazard.  Generally the spillages
                                  98

-------
result in surface water or air  pollution but occasionally the ground
water is affected.  One such occurrence  (cited in Section V), was
first noticed in southern California  in September of 1968 (130)  .  Gaso-
line was noticed in a water well near the  city of Glendale.  The source
of the gasoline was unknown but an  oil company transmission line was
suspected.  The pipeline and many gasoline  storage tanks were carefully
tested and all were reported tight  except  for a few very minor leaks
in the tanks which were repaired.   These small leaks were not the
source of the gasoline pollution which was  quite wide spread.  No leaks
were found in the area where the main problem existed but a leak was
found in a gasoline transmission line about 2 miles from the polluted
area.  This line was drained and removed from service, but the main
source of pollution was not clearly determined.  About 30 wells for
observation, containment, and removal were  drilled around the problem
area and the polluted water was pumped out. There were two principal
removal sites and two plants were set up to separate the gasoline from
the water.  By April, 1970, the gasoline in the water at the two remov-
al sites had dropped to almost  nothing.  Efforts to contain the pollu-
tion and extract it as rapidly  as possible  continued.  Monitoring of
the area seemed to indicate that the  main  problem of the spill had
been controlled.

This spill of gasoline into the ground water in southern California
was an unusual example of a source  of ground water pollution.  However,
when accidents of this nature do happen, the results can often be very
damaging.  The Water Quality Act of 1970 required the establishment
of a national contingency plan  for  the accidental spills of hazardous
materials.  The national plan also  calls for regional plans which have
not yet been completed.  Warning and  monitoring systems should be
established and methods should  be researched for containing and cleaning
up accidental spills of hazardous materials.

             Water From Fault Zones and  Volcanic Origin

Most ground water which emerges as  mineralized springs is deep-seated
water as opposed to  "shallow" ground  water moving through materials
closer to the earth's  surface under ordinary hydrostatic pressures.
Deep-seated waters have a complex origin,  that is, they may include
water derived by absorption from the  land  surface, water trapped in
sedimentary rocks at the time of their origin, and water expelled
from igneous rocks during crystallization.  Milligan, Marsell, and
Bagley  (187) state the following in relation to the origin of these
waters:

           "It is believed that  the  movement of these deep-
     seated waters  is not due to hydrostatic head, or in
     other words, these waters  are  not connected with over-
     lying and connecting bodies of water.  The flow of these
     deep-*eated waters is believed due  to  thermal and pressure
     gradients operative deep within  the earth.  A spring with

                                  99

-------
     constant flow not subject to seasonal changes and with
     a high temperature probably has a deep-seated origin.
     Further evidence as to the deep-seated origin of mineral-
     ized spring water is the presence of important faults or
     other structures along which water could rise."

These deep-seated waters usually come forth as fault springs, volcanic
springs or fissure springs.  Most of the mineral and thermal springs
of the project area originate from deep-seated waters .

•Throughout the study area there are many mineral springs .  Many of them
may also be classed as thermal springs since the temperature of the
water is higher than the normal ground water of the area.  In fact,
most of the significant mineral springs of southwestern U.S. are of the
"thermal" category.  Milligan, Marsell and Bagley (187)  made a detailed
study of mineralized springs in Utah.  They determined that almost all
of the mineralized springs in Utah have elevated temperatures and also
are closely associated with zones of geologic faulting.  Mundorff (188)
in studies of thermal springs in Utah, arrived basically at the same
conclusion.  In Arizona, Peth (189, 190)  reports on a number of miner-
al springs which originate in the Mogollon Rim in Central and East
Central Arizona.  These springs discharge large quantities of dissolved
minerals into the Salt River continuously.

Waring (191) and Stearns, Stearns, and Waring (192)  have reported on
thermal springs in the U.S., and also in other parts of the world.
They indicate that most thermal springs also contain a high concentra-
tion of minerals.  Waring (191)  reports over 200 thermal springs in
California, about 200 in Nevada, 65 in Utah and 21 in Arizona.  The
majority of them are associated with geologic fault zones or volcanic
origins.  In a limited number of locations the waters are of surface
origin having been heated by a volcanic source but not originating
there.  White (193) reported on studies relating thermal springs and
volcanic activity.  A discussion of the occurrence of thermal and
mineral springs at various locations in the project area is presented
in the following paragraphst

ARIZONA
The central and southern parts of the state of Arizona are occupied by
mountains composed of Crystalline rocks and folded and faulted ancient
marine strata.  In many areas these older rocks are covered by Tertiary
volcanics which provides a source of heat for a number of the thermal
springs of the state.  The faulting along the Mogollon Rim has also
provided an escape route for much underground water along the fault
surface as has already been mentioned.  Three main springs in this
area, flowing 900 to 1100 gallons per minute each, deposit over 200
tons of dissolved solids into the Salt River daily.  In the Grand
Canyon of the Colorado, the Lava Warm spring erupts near Lava Falls
                                 100

-------
Rapids.  In this  area  there  is  a spring flow of 6700 gallons  per
minute.  Akers  (194) reports on water from fault zones  in  the Flagstaff
area.

CM.IFORMIA

The volcanic  activity  in California'has been responsible for  many
thermal springs.  Mt.  Shasta is the most prominent of the  lava masses.
In the extreme  northeastern  part of the state near Lake City, White
(195) reported  on violent mud-volcano eruptions at Lake City  Hot
Springs.  The Clear Lake basin  in the coastal mountains northeast of
San Francisco contains many  hot springs, including "The Geysers" and
others.  Many of the springs in this area contain high  sulfur content
(196, 197)  and  in some springs  a considerable amount of nitrate is
found  (198) .  In northeastern part of the state, a number  of  springs
rise from fault zones  in Surprise Valley.  Further south in Honey Lake
Valley, springs with temperatures near the boiling point are  found.
Along the Sierra Nevada range of mountains considerable faulting has
occurred in southern portions in the granite or gneiss  formations and
a number of springs issue forth there.  In the Coastal  Range, in
addition to "The Geysers" already mentioned, there are  a number of
warm mineralized springs originating in fault zones or from volcanic
rocks.  A number of extremely warm springs issue forth  from  the San
Bernardino  and  San  Jacinto mountains, especially in the areas of
geologic faulting which is extensive.

Probably the  most famous fault  in California is the San Andreas Fault
which extends from  Tomales Bay, north of San Francisco, more  than 600
miles -southward into the Salton Sea basin.  No well-known  thermal
springs issue forth, but it does include a number of mineral  springs
which  are of  local  importance.   The same is  true for the  California
desert area,  but a number of resorts use water from mineral  thermal
springs—both in the desert and other areas of the state.

In terns of total flow, the  Paso de Robles thermal spring  is  the largest
in the state, with  a flow of 1700 gallons per minute and a temperature
of 105° F.

NEVADA

Most.of Nevada  is a region of detached mountains separated by desert
valleys.  Many  of the  mountains are composed of granite and  ancient
metamorphic and sedimentary rock; others are composed chiefly of lava.
The structure includes much complex folding, but in many places it is
dominated by  block  faulting.  Thermal mineralized springs  are scattered
throughout  the  state and most are closely related to faults.   In north-
eastern Nevada, several hot  springs issue from limestone and  shale
mountain areas.  Near  the northwest border, a number of springs 1Ssue
from intrusive  granite.  Numerous warm and hot springs  rise  from  lava
hills  along the western side of Black Rock Desert west of  Winnemucca

                                  101

-------
and also further south in the area of Pyramid Lake.

The valley of the Humboldt River east of Winnemucca is bordered by
hills of lava which yield a nunLex of mineralized warm springs.  South
of the Humboldt River Valley a number of boiling springs issue from
faulted strata.  These springs deposit considerable calcium carbonate.
Boiling springs also issue from several lava areas south of this valley.

A few miles southeast of Reno, the Steamboat Springs rise with water
near boiling temperature which contains high concentrations of silica
and sulfide minerals.  In the central part of Nevada, the Big Smoky
contains many hot springs, and similar conditions exist in Diamond,
Steptoe and White Pine Valleys nearby.  In southern Nevada several
wide flat valleys contain warm mineral springs under artesian pressure .

UTAH
Most of the mineral and thermal springs of Utah occur in the fault
zones along the Wasatch mountain range, extending north and south
throughout the whole of the state .  A number occur in the Great Salt
Lake Desert lands of western Utah—Locomotive Springs along the Hansel
Valley fault in northwestern Utah, Promontory Point Hot Spring on the
east side of Promontory Point, Blue Spring hear Howell, Grantsville
Warm Springs near Grantsville, Big Spring near Timpie at the north-
western tip of the Stansbury mountains, Deseret Springs in Skull
Valley, Fish Springs near Callao, and the Gandy Warm Spring near Gandy .

The mineralized springs in Utah have a pronounced effect in degeneration
of the quality of surface streams at a number of locations throughout
the state .

              Evapo-Transpiration of Native Vegetation

In the preceding paragraphs the effect of irrigation on the pollution
of ground water has been discussed.  The process by which the water
remaining in the soil increases in mineralization is exactly the same
for native vegetation as for irrigated crops.  Only the source of the
water applied is different, since with native vegetation the source
must be either soil moisture applied as rainfall, or the ground water .
Use of direct rainfall by vegetation does not have an appreciable ad-
verse effect on ground water quality because the rain water is of good
quality.  On the other hand, ground water containing dissolved minerals
is subjected to a concentrating action as the vegetation utilizes some
of the water leaving the salt behind in solution.  For many types of
vegetation the effect is minimal, but in the case of water-loving vege-
tation called phreatophytes, the gross effect on the loss of the water
resource and on the increase in the mineral content of the ground water
is very great.  In several parts of the project area, large areas of
the native phreatophytes are considered to be a serious problem.


                                 102

-------
Fletcher and Elmendorf  (199)  estimate  a total  area of eleven million
acres of phreatophytes  in  the fourteen western states with  the follow-
ing estimates for  the four states of this  report:

                               Area of        Annual Water

          California           317,000         1,150,000
          Nevada              2,801,000         1,500,000
          Utah                1,200,000         1,500,000

          TOTAL               4,723,000         5,430,000

Detailed investigations  have  been conducted on the characteristics of
phreatophytes.  Robinson (200)  discussed 74 different species in de-
tail.  Studies of  the water using characteristics and water quality
effects of phreatophytes have been reported by Robinson (201, 202), by
Muckel and Blaney  (203,  204),  by  Shamberger (205), by Gatewood and
others (206), by Lewis  (207,  208)  by Bowie and Kam (209), Hendricks
and others  (210) and by  Turner and Skibitzke  (211) .  These reports
include work in all  of the project area.  All  of these reports empha-
size the fact that the phreatophyte effect upon ground water quality
is considerable.

                 Injection Wells  for Waste Disposal

Injection wells are  sometimes used in  connection with ground water
replenishment programs and have already been discussed in an earlier
sub-section.  In the oil industry,  brines  are  often re-injected under-
ground as a means  of disposal and also as  a secondary oil recovery
operation.  This has also  been discussed in a  previous sub-section.
Occasionally, industries or others have used shallow injection wells
to dispose of liquid wastes.   For example, Follett (94)  reported that
various electronic industries near Phoenix and Tucson, Arizona,  have
in the past, disposed of metal plating wastes  by injection wells.
Follett reported that heavy metals,  primarily  chromium,  showed up in
the ground waters  of the areas involved but this method of waste dis-
posal has now been stopped.  Deep injection wells have been considered
for disposal of radio-active  wastes (212,  213) .  An analysis of relative
cost of disposal by  injection  for municipal wastes,  failed to consider
the pollutional aspects  of such practices  (214) .

In 1967,  it was estimated  (215) that there were 40,000 salt brine
disposal wells in  U.S. and 110 injection wells  to dispose of pther
wastes.  The number  in the project area is not known.  Smith (216)
stated that most disposal  wells are  successful  and that only a few give
the method a bad name .   Sheldrick  (217)  indicated that earthquakes in
                                 103

-------
the Denver area were likely caused by injection at the Rocky Mountain
Arsenal.  Piper (218)  pointed to the need for better information and
better controls on injection.  He also indicated that the maintenance
of a given pressure condition is simplified if wastes withdrawn (such
as brines in oil well development)  are re-injected into the same aqui-
fer.  On the other hand, many of the deep aquifers contain large
volumes of gas which can be compressed; and under these conditions, in-
jection of large volumes of liquid does not cause a serious problem
from a volume of pressures standpoint.  Wesner and Baier (219)  dis-
cussed injection of reclaimed wastewater underground.  It is the belief
of the writers that deep-well injection involves many potential pollu-
tion hazards .  It is not possible to generalize in a discussion of pro-
blems related to deep-well injection because of the great variation in
geologic conditions at various locations .

                 Fertilization of Agricultural Lands

The problem of irrigation return flow in water quality control and the
need to maintain a "salt balance" in arid region soils has already
been discussed.  The principles which are operative in relation to the
salt balance also impose another water pollution potential on the
agricultural operation.  As fertilizers and water are applied to the
soil, part of the fertilizer will be leached on through the soil in
the drainage water.  This is especially true of nitrates.  Pratt (129),
Doneen  (132, 133)  and Jopling (220)  all indicate that part of the ni-
trates in solution in irrigation water are carried on through the
rooting zone of the plants into the drainage channel or the ground
water.  Phosphate fertilizers do not becone a problem in this regard
because they are adsorbed on the soil particles and become "tied up"
in the soil.  Stout and others (108) traced the movement of nitrogenous
matter from the ground surface ,to the water table.  Robbins and Kriz
(221) discussed the general problem of , fertilizers in causing ground
water pollution.  They report a number of research reports which point
out the potential hazard of over-fertilization in ground water pollu-
tion.  However, they point out that the extent of fertilizer use will
likely increase in the U.S. in the future.  It should be pointed out
that the plants use a part of the nitrogen in solution, but a portion
usually remains with the percolating water to become a ground water
pollutant.  Nitrogen is the only fertilizer element that has been
found to be a problem related to ground water pollution.  This is a
potential problem throughout the study area but has only been identi-
fied as an actual source of pollution in a few areas.   It certainly is
the cause of nitrate pollution of ground waters at some locations and
is likely an important factor in many others .  As noted in the previous
chapter, there are many locations in the study area where nitrates are
dangerously high.  Fertilizers undoubtedly contribute to the hazard in
many of them.

          Land Disposal of Wastes-Municipal  and  Industrial

Land disposal of  wastes is practiced at many locations throughout the
U.S.  Since agricultural wastes  are  being  discussed  in other sections
of this report, this  section  deals only with the land disposal of
municipal and industrial wastes.

MUNICIPAL WASTES
There are a number of  municipalities which dispose of  sewage wastes by
spreading on the  land.  If  this  practice  is controlled carefully and if
a large enough  area  is used for  disposal,  it is  not likely to cause
ground water pollution.  Undoubtedly there are many locations where
this is done in a safe and  satisfactory  manner.   It is also likely that
there are a number of  examples of this method of disposal where pollu-
tion caused by  this  method  of disposal has gone  undetected.  In the
course of the investigation leading to  this report, ground water pollu-
tion problems in  the vicinity of a number of municipal sewage treatment
facilities suggest this as  a source of  pollution.

At Tucson, Arizona,  a  project to reclaim waste water involves land
spreading of sewage  for irrigation purposes (24) . In  the early stages
of this project,  considerable nitrate was getting into the ground water.
At Phoenix, Arizona, Bouwer (222, 223,  224)  reported on the results of
research on land  spreading  of municipal  sewage plant effluent.  His
results indicate  limited travel  of the various pollution parameters,
McMichael and McKee  (225) reported on similar studies  in the Los Angeles
area at Whittier  Narrows.  Their work was oriented toward the degree of
treatment of municipal sewage effluent prior to  its application to
water spreading grounds used to  replenish the ground water supplies.
Surface disposal  of  sewage  effluent in  the Fresno metropolitan area is
reported to have  degraded the quality of  ground  water  in the area of
the sewage treatment plant  (134) ,  In San Bernardino and Riverside
Counties of California, studies  were reported in 1965  (226) relating
to the dispersion and  persistence of synthetic detergents in ground
water—again relating  to the spreading  of sewage effluent for the re-
plenishment of  ground  water supplies.

INDUSTRIAL WASTES
Land disposal  is  a common method of handling of  many  industrial wastes .
Throughout the four states of  this study,  there  are many locations where
industrial wastes are disposed of in this  manner.  As is the case with
many waste disposal practices,  pollution may occur and yet remain un-
detected.   Cne example of industrial waste land  disposal becoming a
problem  has been  reported in the vicinity  of Hollister, California, in
the Pajaro River  Basin (99) .  Two canneries disposed of wastes from
their  canning  operation in stream terrace  deposits and alluvium.  In
addition to food  products residue,  their waste water also contained
caustic  soda used as a peeler  for apricots and tomatoes ,  Most of their
                                  105

waste water reached the ground water body.

                 Seepage of Polluted Surface Waters

In many instances, careless practices related to control of wastes
result in surface streams becoming polluted.  Often this water finds
its way into the ground water.  Several examples of this type of
pollution have been observed in the study area.

In the Vernon district of the Los Angeles metropolitan area, ground
water pollution from industrial waste discharge into Compton Creek
was reported by Zielbauer  (227) in 1947.  High concentrations of
total dissolved solids as well as sulfates, chlorides and phenols were
reported.

In the area of Barstow, California, the Mojave River channel is a dry
bed most of the time—except during infrequent periods of storm run-
off .  Both municipal and industrial waste disposal into the river
channel created a serious ground water pollution problem.  A series of
reports in 1960  {228), 1966 (229) and 1970 (143) indicate that phenols,
detergents, chrome, and MBAS (methylene Blue Active Substances) were
present in nearby wells.  Objectionable tastes and odors were also
found in the area ground water, variously characterized as "chemical",
"medicinal", "sulfide", "musty" and sewage".  The study in 1960 indi-
cated that phenol and chrome wastes came from the railroad shops,
resulting from large quantities of diesel oil (24,000 gallons per
month) and cooling system drainage (containing hexavalent chrome as a
corrosion inhibitor) being wasted to the river channel.  A large part
of the detergent was believed to have come from the railroad laundry,
which had operated between 1949 and 1959 when it was closed by the
company.  Most of the sewage was believed to have come from the Bar-
stow City sewage plant which was re-de signed and rebuilt in 1953 and
again in 1968.  The railroad company domestic sewage was treated
separately until 1968 when it was included in the city plant.  The
underground flow in the Mojave River Basin was estimated by the U.S.
Geological Survey  (230, 231) at about one million gallons per day.  The
California Department of Public Health estimated the velocity at one
mile in five years  (229) .  One surprising result of the studies in the
Barstow related to the persistence and spreading of the degenerated
water after extensive corrective measures were taken.

Both the railroad company and the City made extensive improvements to
eliminate the sources of pollution between 1960 and 1970, yet the 1970
report (143)  indicated additional expansion of the degraded water and
its advancement to wells where it had not appeared previously.

                            Urban Runoff
Urban storm water disposal is often accomplished by spreading in areas
of high infiltrations.  Abandoned gravel pits and old stream channels

                                 106

-------
are examples of areas  utilized for this purpose.  This practice is
often encouraged in arid  regions  as a means of replenishment of the
ground water supply.   These practices are  used at many locations
throughout the project area,  and  they represent a potential ground
water pollution hazard.  No specific reported instances  of pollution
of ground water by this means are available to us,  but the potential
certainly exists.

It is common practice  in  areas of freezing weather to scatter salt on
icy roads to melt  ice  and snow as a traffic safety measure .  In urban
areas, the runoff  from this melting ice and snow is collected in the
storm sewer and conducted to some disposal location. Often the dis-
posal is underground.   The resultant increase in total dissolved
solids in the ground water may be a problem.  This is particularly
true in arid regions,  where dissolved minerals in many waters are
already near the critical level.

Considerable urban development is occurring in mountain  areas away
from the traditional urban areas .  Sewage  disposal in these areas is
often into septic  tanks,  with a resultant  detrimental effect on ground
water quality areas.   No  actual measurements of such pollution are
available to us, but a number of  such areas are known to exist at
several locations  in the  project  area.  These areas should not be con-
fused with recreational home developments  which are used only season-
ally.

                       Connate Water Withdrawal
 Brines  are often found in the sedimentary deposits of the  earth 's
 crust.   Many brine deposits are connate—that is,  water trapped in the
 sediments as they were being deposited.  They often occur  in places
 where no oil or gas fields are present.  The entrapment of the brine
 may  in  some instances have been brought about by an overlying body of
 water or a water bearing aquifer with interconnections to  the aquifer
 containing the brine .  As the less saline water is pumped  from the
 overlying aquifer, the salty brines may be withdrawn in much the same
 manner  as sea water intrudes into a fresh water aquifer.  Such with-
 drawal  is always the result of over-pumping of the existing water
 supply.

 In the  study area, there are no known locations of connate water with-
 drawal  except in connection with oil well development, which wxll be
 discussed in the next section of this chapter.  However, the potential
 for  such withdrawal is present wherever brine deposits underlie the
 better  quality waters.  Some connate water withdrawal has  been indi-
 cated by high salinity in some heavily-pumped wells of the San Joaquin
 Valley  (138).

                          Mining Activitie s

Most mining activities encounter ground water, and disposal of the
drainage water from the mine workings is often one of the troublesome
problems of the whole operation.  Ordinary excavation procedures do
not usually have any direct adverse effect on the quality of the
drainage water except for the causing of some turbidity.  However, in
coal mine workings, the mining usually exposes pyritic material which,
upon contact with percolating water and the oxygen in the mine shaft,
forms sulfuric acid.  However, in most arid regions, the soils and
natural waters are alkaline; and thus tend to neutralize the acid.
For this reason, acid mine drainage is not as serious a problem in the
project area as it would be in other parts of the country.  No indica-
tion of any problem has been given by any federal, state or local
officials in any of the states of the study area.

Drainage of waters from copper deposits often contain considerable
metallic copper, and ground waters in the vicinity of copper deposits
s&uch as occur in Arizona and Utah should be carefully checked if this
is a potential problem.  However, drainage waters are often "processed"
to salvage the copper present.

Many natural minerals which can cause serious ground water pollution
occur in the project area.  One would naturally expect that ground
water in the vicinity of these natural deposits could be contaminated.

                         Aquifer Interchange

The exchange of ground water from one aquifer to another represents
an important potential source of ground water pollution.  It is known
that quality of ground water varies considerably from one aquifer to
another.  One aquifer may contain a source of pollution which another
does not.  Common well drilling practices may permit the movement of
water from a polluted aquifer into another which is relatively free
os pollution.  There may be aquifer connections at springs or geologic
fault zones.  Measured information is not available to indicate the
degree to which an interchange of water between aquifers actually
occurs, and it is not possible to state locations at which such a
problem may occur.  Investigations in the San Joaquin Valley of Cali-
fornia (232)  indicate the possibility of interchange between aquifers
since wells drilled through shallow brackishwaters are frequently
gravel-packed and perforated in all water producing zones.  It should
be recognized as a potential problem that could exist in the project
area.

                Mineralization From Soluble Aquifers

The effect on ground water quality of flow of water through aquifers
containing soluble minerals is difficult to measure.  Nevertheless, it
is a significant factor in the quality of ground water.  In Nevada and

                                 108

-------
Utah many of the ground water basins  are  closed  basins with alluvial
fill in the valley.  The natural  recharge water  flows from the outer
edges of the valley toward the  center of  the valley and in the process
minerals are dissolved into the ground water.  Therefore, the ground
water near the center of the closed valleys generally has a high con-
tent of total dissolved solids .  Normally, impermeable rocks exist be-
tween basins so most ground water reservoirs consist of the internal
drainage within the basin.  Under these conditions, the quality of the
ground water is good near  the recharge areas at  the edge of the valley
and becomes progressively  poorer  quality  toward  the center of the
closed valley.  Evaporation of  accumulated surface water at the low
point in the closed basin  results in  the  accumulation of salts at the
surface and these  salts are often carried to the ground water reser-
voir by recharge water seeping  from the surface  to the ground water
reservoir.  This process also tends to pollute the ground water near
the center of the  valley more  severely than at the valley edges.

Since the best quality ground water is around the periphery of a
closed valley, most of the wells  for  developing  the use of the ground
water, are drilled near the outer edges of the valleys.  If the water
pumped per year is more than the  natural  recharge, the ground water
table begins to go down.   If this trend continues, the water table
at the edge of the valley  is lower than at the center of the valley
and there is a reversal of the  flow of the ground water.  The water
toward the  center  of the valley begins to flow toward the outer edge
of the valley.  Since  the  water from  the  central part of the valley
is generally more  highly mineralized  than the water in the natural re-
charge area, the  quality of the water in  the well begins to decrease.
Therefore,  development of  the  ground  water use is the cause in some
areas of a  deterioration of the ground water quality.  A number of
investigators have found a general degradation of water as it moves
through an  aquifer in  a  direction away  from the  point of recharge.  In
the Santa Ana area (128),  and  the San Joaquin area  (138) of California
and in a number of other regions  of the project  area, the ground water
has been shown to  become degraded as  the  water moves through the
ground water aquifers .

                    Crop  Residues  and  Dead Animals

Crop residues include  that portion of the plant  that is left in the
processing  shed after  the  harvest. For every pound of food that gets
to the store to be sold, between  2 and  5  pounds  of residues are left
in the field and  the packing shed.  In a  few specific cases, crop
residues might become  a  ground water  pollution problem.  In general,
however, crop residues are not a  pollutant to the ground water.  In
fact, residues are not generally  a very serious  pollutant to agncul-
tural waste waters (233) .

Dead animals do not  ordinarily have any serious  effect on ground water
          Larger  farm  animals  are usually disposed of by the rendering

                                  109

-------
and animal by-products processor.  The dead sheep or wildlife on the
range are usually disposed of quickly by other forms of wildlife.
According to Hart  (233) and Rabbins and Kriz  (221) the disposal of
dead poultry is often done in such a manner that it creates a serious
ground water pollution hazard.

Poultry producers are handling ever-increasing numbers of fowl in their
operations.  Flocks of 100,000 are common.  A loss of one per cent per
month from a 100,000 fowl flock will average 35 dead fowl per day.
Many producers dispose of the dead birds by burial in a large trench
or in a septic tank.  With percolating waters in the vicinity of such
a mass of decaying organic matter, the pollution potential is consider-
able .  No actual reported instance of such pollution in the project
area is known, but there are many poultry producers in the area so
the potential does exist.

                         Pesticide Residues

The term  "Pesticide" covers any material used to control, destroy or
mitigate pests; and includes insecticides, herbicides, fungicides,
nematocides, rodenticides, bactericides, growth regulators and de-
foliants.  Whenever these materials may be found in the ground water,
the consequences can be serious.  Rotbins and Kriz (221)  point out
that there is insufficient information available on many facets of the
problem.  For example, the movement of various pesticides from the
surface of the land through the soil to the ground water cannot be
verified in many cases.  More information is needed to know which of
the various pesticides may be degraded by interaction with the soil.

The fate of pesticides once they have entered waste waters is a sub-
ject of much speculation.  According to Westlake (234), many disappear
quite rapidly—through adsorption by plants, adsorption on clay parti-
cles, chemical decomposition, and action of micro-organisms.  Organo-
phosphorus compounds, as a rule are relatively short-lived in water
courses or soils.  Organochlorine compounds may persist for long
periods of time in water sources, but often are not moved through the
soil, but are decomposed in the soil.

Scalf and his colleagues (235)  studied movement of DDT and nitrates in
a ground water recharge experiment in Texas and found that the nitrates
moved readily with the recharge water but that essentially all of the
DDT was adsorbed on the sand particles of the aquifer.  The solubility
of the pesticide seems to have a significant effect upon the movement
through the soil.  In studies in the San Joaquin Valley (236) using
Lindane and DDT the .investigators found that the pesticide DDT being
of low solubility did not move through the soil into the ground water
in significant amounts, whereas Lindane, of higher solubility did move
into the ground water in significant amounts.  They also pointed out
that more chlorinated hydrocarbons are removed through decomposition
in the soil than through leaching.

                                 110

-------
Pollution by pesticides  must be  listed as  an important potential
hazard throughout  the project area.   However,  in  all of the litera-
ture studied and the many interviews  conducted in compiling data for
this report, no evidence was reported of any measured pollution from
pesticides.

              Land Subsidence Effects on Water Quality

In a previous section  we referred briefly  to a problem of arsenic
pollution of ground water in the San  Joaquin Valley of California.
Lofgren  (137) has  expressed the  opinion that the  arsenic may have been
the result of land subsidence, which  is extensive in the area where
arsenic  is found.   His  theory is that the  arsenic has adhered to clay
particles, and as  the  pressure is increased in the soil due to the
subsidence of the  land,  the arsenic goes into  solution.  There is a
considerable area  in  California  subject to land subsidence, but no
other relationship between subsidence and  water quality has been
suggested at any other location.  Miller,  Green and Davis (237) report
subsidence in excess  of 20 feet  at some locations in western San Joaquin
Valley of California.

                             Other Causes

SEWER LEAKAGE

Many sewer  systems are constructed with poor joints with the result
that leakage from the sewer may  result in  areas where the sewer line is
above the ground water table.  This represents a  potential threat of
contamination of  ground water.  Recent pipe laying practices often re-
quire the use of rubber gaskets  at the joints  with a greatly diminished
pollution potential.

THERMAL  POLLUTION

It is well known  that ground water temperatures at some locations in
the  country have  increased with time.  Many industries dispose of
heated wastes to  the  ground water. No specific instances of such
thermal  pollution  problems are known  in the project area, but undoubt-
edly there  are  some locations where  this problem  exists.  A rise in
ground water  temperature can have a serious detrimental effect on many
users.

RADIOACTIVITY

in the Milling process of uranium ore, there are  tailings left which
might have  a pollution potential for  radioactivity of 1
-------
in tailing piles that have some radio-active materials.  Although they
are not known to be an active source of ground water pollution, they
would appear to be a possible source .

Natural radioactivity occurs to some extent in all ground water, as a
result of decay products of uranium, thorium, or radium which occur
in natural formations.  No instances of a detrimental amount of radio-
activity are known to exist in the project area.

RECREATIONAL ACTIVITY
The project area includes large areas of public and private land which
are used much of the time for recreational purposes.  There has been
a great increase in recreational use of lands in recent years.   Camp-
ing, hiking, motorcycling, horseback riding,  fishing,  boating,  skiing,
snowmobiling, and hunting are all examples of recreational uses of
land and water within the project area.  These uses have had a  great
impact upon the surface water quality and to  a lesser  degree upon
ground water quality.  Use of this type will  likely increase greatly
in the future and the net effect on ground water quality may be con-
siderable .

                               SECTION VII

                        RESEARCH AND OTHER NEEDS


There is a vast amount  of written  material bearing on the subject of
the ground water supply and  the pollution thereof.  The many refer-
ences in the bibliography of this  report attest to that fact.  On the
other hand, almost no research has been devoted to the solution of
the problems related to ground water pollution.

It will be noted that many of the  "research needs" listed involve
investigative evaluations or studies of an applied nature.  The authors
believe that there is a great need to bridge the gap between fundamen-
tal or basic knowledge  and the practical application of knowledge to
every day problems.  This is especially true in the field of ground
water pollution, where  the variables are many, and where the greatest
promise for useful research  appears to lie in  the "applied" area.

         Determination  of Ground Water Development Potential

It is the belief of the authors that many ground water quality pro-
blems are inseparably connected to water quantity problems.  Over-
development of a given  ground water aquifer often results in a deteri-
oration of the water quality—sometimes dramatically as is the case
when sea water or connate brine comes into an  over-developed well.
There is surprisingly little quantitative information available
which will enable the water  resources engineer to define the quantita-
tive limits of ground water  development.  There are few locations
where these limits have been defined. They are sorely needed by
engineers and water administrative officials wherever ground water is
used.  McGuinness (15)  made  a great contribution in summarizing the
best estimates available of  ground water development potentials.  His
estimates were based on geologic and other limited information with
no claim to accuracy sufficient to define development limits.  He
stated  "Existing knowledge is grossly inadequate to form a basis for
effective development and management of the ground water reservoirs."
Techniques for evaluation of pumping and recovery data are available,
which will permit determination of the quantity of available ground
water supplies.  This should be done for all ground water basins where
appreciable development exists or  is contemplated.

         Research on Ground  Water  Pollution identification

This report is based upon a  thorough review of the literature and
personal interviews with various officials having knowledge of ground
water pollution problems existing  in the study area.  Through these
sources, many ground water pollution problems  have been identified and
reported.  We believe that this identification is a necessary first
step in solving ground  water pollution problems.  It is our conviction


                                   113

-------
that similar reports should be prepared for other parts of the country.
Aside from the inventory value, such reports can serve as a basis for
research projects to attack the problems of ground water pollution in
the respective areas of the country.  We recommend that such studies
be conducted throughout the United States.

               Besearch and Investigation on Specific

                         Pollution Problems

In the previous section, the existing ground water pollution problems
were listed and classified according to the various causes of pollu-
tion .  Listed below are recommended research ideas aimed at solutions
of some of the problems listed.  The list is not intended to be all-
inclusive, but to serve as a guide for research which the authors feel
can be productive in solving ground water pollution problems in the
states of Arizona, California, Nevada, and Utah.  The suggestions are
classified according to the "causes" listed in  the previous section and
are presented in the same order as previously.   No attempt has been
made to establish priorities of suggested research,  since great differ-
ences exist in the magnitude of the problem. Availability of funds
and research capability must have a great influence on the kind,  amount
and rate of any research undertaken.

NATURAL IEACHING

Since this is a natural process,  it is the result of many long term,
complex interactions between water and the earth mantle.  Improvement
programs must either protect the water nearer the source,  short circuit
the natural processes,  or de-mineralize the water.  The following re-
search ideas are suggested:

     1.  In areas of extremely short supply of  water,  study the
         feasibility of demineralization of part of a given water
         supply so that demineralized water may be mixed with raw
         water to obtain acceptable water.

     2.  At locations where surface water supplies are available
         and where satisfactory geologic conditions exist, inves-
         tigate the feasibility of water spreading in re-charge
         areas to dilute natural  mineralization as well as in-
         creasing ground water supplies.

     3.  Study long term records  of salinity in ground water to
         investigate changes in natural salinity with time.
         These studies  would answer such questions as "Does a
         long-term leaching process decrease the minerals in the
         leaching areas, thus diminishing the mineral content
         increase in total quantity and/or in percentage in years
         of high water  supply?"

                                 114

IRRIGATION RETURN FLOW

The Utah State Research Foundation,  in  their  comprehensive report pre-
viously cited (90), made many excellent recommendations for research
on the subject of  irrigation  return  flow.   The authors generally con-
cur in their reconroendations,  many of which relate to ground water
pollution.  The  following  suggested  research  topics include a number
of ideas from their report:

     1.  Conduct studies under a variety of soil mineralization
         and irrigation water quality conditions to determine
         inter-relationships  between salt balance, efficiency of
         irrigation,  and mineral changes in water as it moves
         into and  through  the soil.

     2.  Conduct investigations to evaluate in large scale irri-
         gation  projects,  the increases in  salinity of irrigation
         return  flow  in order to develop techniques for the pre-
         diction of such mineralization increases in new irriga-
         tion projects.

     3.  Conduct basic studies of the precipitation and exchange
         reactions which occur as water moves through mineralized
         soil.

     4.  Conduct basic studies related  to adsorption of phosphates,
         heavy metals, and various agricultural  chemicals which
         may be  carried into the soil with  irrigation water.

     5.  Investigation of  effects of temperature of irrigation
         water on  the pollutional aspects of  the resulting return
         flow and  its effect on the  ground  water.

SEA WATER  ENCROACHMENT

Most of  the work which has been done to fight sea water encroachment
has been of an emergency nature—with procedures and practices being
developed  in the field to  control pollution already existent.  The
following  are suggested research ideas:

     1.  Evaluate  the effectiveness  and efficiency of existing
         fresh water  "barriers" established near the California
         coast to  prevent  salt water encroachment from the ocean.
         Do present barriers use more fresh water than necessary?

     2.  Study ocean-bordering aquifers to  determine storage and
         useable available water so  that over-development can be
         avoided before salt water encroaches into the fresh water
         aquifers.
                                   115

-------
     3.  In areas where geologic conditions are favorable,
         investigate the feasibility of utilizing a physical
         barrier such as a grout curtain to prevent encroach-
         ment .

     4.  Investigate mineralization and geologic conditions
         near highly-mineralized inland seas such as the Great
         Salt Lake in Utah and Mono Lake or the Salton Sea in
         California to determine whether the lake water is
         polluting the ground water.

SOLID WASTES

Disposal of solid wastes is a problem throughout the U .S.  The develop-
ment of methods and techniques for handling the large volume of solid
wastes will require ingenuity and wisdom.  Ground water pollution is
only a small part of the problem.  Legislation and regulatory control
are needed in all states.  This is especially true in relation to toxic
wastes and containers used for highly concentrated materials which may
be toxic.  The following are suggested research ideas:

     1.  Evaluation of ground water pollution resulting from
         various kinds of solid waste disposal areas.

     2.  Development of special techniques for handling highly
         toxic waste materials to prevent ground water pollution.

     3.  Development of uniform requirements for management and
         operation of solid waste disposal areas .

DISPOSAL OF OIL FIELD BRINES AND OTHER MATERIALS
There is a great ground water pollution hazard in the disposal of
brines and other waste materials in the oil and gas fields .  Rigid
inspection and control of disposal techniques is essential on a uni-
form basis .  New legislation will probably be required to insure the
kind of control necessary to protect the ground water resources .  It
is recommended that costs of inspection and control be assessed as a
cost against the drilling operation.  Suggested research ideas are as
follows:

     1.  Conduct detailed geologic and geophysical investigation
         in existing and potential oil and gas fields to evaluate
         potential disposal hazards by re-injection or other
         methods.

     2.  Develop inspection procedures which will insure absolute
         control of ground water quality in drill fields .
                                  116

-------
     3.  Investigate the  ground  water pollution hazards in
         the use of acids to increase aquifer permeability,
         including the fate of the  acid  and possible aquifer
         interconnections brought about  by acid corrosion
         of the well casing.

ANIMAL WASTE

The concentration of large numbers  of animals in a small space has been
a recent development in  the beef, pork and poultry industries.  Pollu-
tion of ground water caused by animal waste has been discussed in pre-
vious sections.  There is considerable reason for concern over ground
water pollution related  to animal waste  disposal.  There is a need for
design standards and management  procedures to cjuide the industry and
the regulatory agencies.  Research  ideas are as follows:

     1.  Investigate the  effect  of  various feed lot and
         poultry management practices on ground water quality.
         Investigations  should include various site conditions
         and various methods of  handling the waste, such as
         spreading on  the land,  treatment by aeration or
         other means,  incineration, etc.

     2.  Develop guide lines for the construction, operation
         and management  of feed  lots in  order to help solve
         the animal waste problems  and protect ground water
         quality.

     3.  Assist  the states in preparation, adoption and enforce-
         ment of standards to protect ground water quality,

     4.  Evaluate management practices,  related to scheduled
         inundation of disposal  of  high-nitrate effluent as
         reported by Bouwer  (223) .

     5.  Investigate the effects on ground water pollution of
         land disposal by the  spreading  of large amounts of
         decomposable  organic material on the land surface.
         Studies should  include  the movement through the soil
         of such substances as phosphates, nitrogenous compounds
         and pesticides  and the  survival and movement of viruses,
         pathogenic bacteria, nematodes  and other such organisms.

ACCI CENTAL SPILLS OF HAZARDOUS MATE RIALS

Accidental spills of hazardous materials represent a constant threat
to gro^d"wa?er  quality. There  is  urgent need for the development of
detection  and control procedures as well as a 'faster" plan to be
rtSowea^irie  event  of such accidental spills.  New legislation may
be needed  to implement such procedures.   Prevention, detection and

                                  117

-------
correction measures are needed and therefore, applied research should
be directed at developing these measures.

WATER FROM FAULT ZONES AND VOLCANIC ORIGINS
In the project area there are many thermal and mineralized springs
which represent important sources of pollution at particular locations
Although these sources are of natural origin,  some research will be
helpful in solving the problems:

     1.  Investigate the geology of the polluting springs to
         determine direction of water flow, source of flow,
         and localized conditions which may make plugging or
         sealing of the spring possible.

     2 .  Evaluate hydraulic conditions at polluting springs to
         determine whether diversion or isolation by increasing
         the overflow "pressure head" may be effective in stopping
         tlie spring flow.

     3.  Extensive work has been done on locating the springs
         with highly mineralized water in the  various states of
         the region.  Research is needed to determine the extent
         of any pollution to the ground water  which these springs
         might be causing.  Then ways should be sought to elimi-
         nate that source of pollution .

EVAPO-TRANSPIRATION OF NATIVE VEGETATION
The prospect of salvaging valuable water now being wasted by compara-
tively useless vegetation, while at the same time decreasing the
accompanying mineralization of the water supply,  has provided an
attractive goal for many engineers and scientists.  Various programs of
vegetation eradication have been attempted with very limited success.
The growth usually returns within a short period of time .  Erosion
resulting during the eradication period has created serious soil loss
problems in the eradication areas and sedimentation problems in the
nearby stream channels.  Nevertheless, the authors believe that re-
search along the following lines could be fruitful:

     1.  Development and evaluation of replacement vegetation
         having lower water use characteristics than the water-
         loving phreatophytes.

     2.  Investigation of the possibilities of leveling areas of
         phreatophyte growth and utilizing the areas for agricul-
         tural production.  Such a program should involve consid-
         eration of subsidization because of the intermittent
         flooding, poor soil conditions and low yield potential.
                                  118

INJECTION WELLS FOR WASTE  DISPOSAL

The use of injection wells to  dispose of wastes  is a rap idly -growing
practice in the U.S.  Much of  this use in  uncontrolled and done with-
out any public record or knowledge.  Pollution possibilities from
these practices are staggering.   It is likely that legislation is
needed to establish control procedures.

Research ideas which may be helpful ares

     1.  Conduct a detailed investigation  to determine, in each
         of the states, deep well injection policies, controls,
         practices and existing  injection  programs  (including
         volume and quality of all injection material) .

     2.  Conduct geological and  geophysical investigations at
         existing and potential  injection  sites  to evaluate
         possible aquifer  interconnections, hydrostatic pres-
         sure and storage  capabilities—such investigations to
         serve as a basis  for  establishing policies for the
         use of injection  wells  as a means of waste disposal.

     3.  Encourage states  to develop means of prohibiting deep
         well injection where  it will decrease the ground water
         quality.

     4.  Develop guide  lines for controlling the use of injec-
         tion wells for waste  disposal.

     5.  Make a study  of  several injection well  operations under
         various aquifer  conditions to determine whether or not
         the ground water  is being polluted by the disposal of
         various waste materials.

FERTILIZATION OF AGRICULTURAL  LANDS

There are many elements necessary for plant growth.  In addition to the
carbon, hydrogen and oxygen taken from air and water, the plants re-
quire nitrogen, phosphorus, potassium, sulfur, calcium, magnesium, iron^
manganese,  Zinc, copper,  boron,  molybdenum and a number of other  minor
elements.   Some of these  elements are required in only minute amounts
and  are usually present naturally to most  soils,  but three--nitrogen,
potassium,  and phosphorus-are usually added in  great amounts,  ^search
to date has indicated  that nitrates go into solution as water is added
to the soil, and often  move through the soil into the ground water.
Phosphates  appear to be adsorbed on the soil particles, and do not move
into the ground water.  Potassium is not known to cause any Problem.
More research is needed,  and the following ideas are suggested:
                                   119

-------
     1.  Investigate the movement through the soil and the
         fate of various fertilizer additives—nitrogen, phos-
         phorous, potassium, or others that could cause a ground
         water pollution problem.

     2.  Evaluate various fertilizer application and management
         practices especially to include the time of fertilizer
         application as related to the time of heaviest water
         application in order to minimize leaching away of
         fertilizer elements.

     3.  Investigate relative ground water pollution under programs
         utilizing slow-release fertilizers now available or others
         that may be developed.

LAND DISPOSAL OF WASIES - MUNICIPAL OR INDUSTRIAL

Many municipal and industrial wastes are disposed of by spreading on
the ground surface—in both liquid and solid form.  Procedures govern-
ing such spreading and research to evaluate pollution hazards are
needed.  Research suggestions are as follows:

     1.  Evaluate ground water pollution potential of land dis-
         posal practices, especially including the ultimate fate
         of toxic materials or any potential pollutant which may
         be involved.

     2.  Develop guide lines defining characteristics of good land
         disposal sites .

     3.  Develop management practices which may permit land dis-
         posal of certain wastes, including "rest" periods for
         disposal areas and cultivation practices in disposal
         areas .

SEEPAGE OF POLLU'EED SURFACE WATERS

Whenever polluted surface waters seep into the ground they constitute
a potential ground water pollution hazard.  Needs in this category are
essentially preventive—prevention of the pollution of surface waters,
or management of them to prevent infiltration.

URBAN RUNOFF
Storm drainage from urban areas inevitably picks up various pollutants.
Degradable organic pollutants or bacteria are not usually a problem to
the ground water since they are not usually transmitted through the
soil mantle.  Toxic materials and phenols could be a problem.  Salt
used to melt roadway ice and snow in winter constitutes a serious poten-
tial problem—especially in arid regions where mineralization is a

                                  120

-------
primary cause of  water  quality degradation.  Research  ideas are as
follows:

     1.  Study  the winter urban runoff,  in areas where salt is
         used on  roadways, to evaluate mineralization of the
         groundwater by such practices.

     2.  Develop  guide  lines relating to treatment of urban
         waste  waters which may be used for ground water replen-
         ishment .

     3.  Evaluate the extent of ground water pollution from urban
         developments in mountain areas.

CONNATE WATER WITHDRAWAL

Connate water withdrawal may result when a fresh ground water aquifer
is over-developed.  Efforts to prevent ground water pollution by this
means  should concentrate on a determination of aquifer development
limits.  Research along these lines is suggested:

     1.  Study  all producing ground water aquifers to determine
         storage  and useable available water so that the develop-
         ment  limits may be determined before over-development
         occurs.

MINING ACTIVITIES
 Mast mining activities intercept ground water .  In most mines the water
 quality is  probably not affected appreciably.  However, in mines where
 pyritic formations are exposed to air and water,  sulfuric acid drainage
 may result.  Research and investigation suggestions are as follows:

     1.  Investigate the characteristics of drainage from mines
          wherever it exists in appreciable amounts.

     2.  Evaluate ground water pollution potential of the mine
          drainage to determine whether treatment  of the drainage
          water is necessary before it is permitted to mix with
          natural waters.

     3    Evaluate mining practices to determine methods which
          might be utilized to control natural drainage from the
          mine after it becomes inactive.

 AQUIFER INTERCHANGE

 interchange of ground water from one aquifer to another is usually the
 rlsult  S Improper drilling practices.  Control of drilling practices
 S all  state? should include provisions to prohibit promiscuous

                                   121

-------
perforation of well casings at many different aquifers in the same
well which so often occurs.  Suggestions for research are as follows:

     1.  Develop policies and procedures which will result in
         well drilling methods that will help assure that there
         is neither a planned nor an inadvertent interchange of
         waters between different aquifers.

     2.  Develop procedures by which evaluation of intermixing
         of aquifers in existing wells can be made, followed by
         selective sealing of some aquifers or complete sealing
         of the entire well if necessary to protect water quality.
         This would be especially important for abandoned wells.

MINERALIZATION FROM SOLUBLE AQUIFERS

Since this is primarily a natural process, it is not likely that
corrective or preventative measures can be taken.  As competition for
water increases polluted waters from these sources may need to be
made useable by some demineralization process.

CROP RESIDUES AND DEAD ANIMALS
Crop residues and dead animals constitute a potential source of ground
water pollution, particularly from nitrates resulting from the decompo-
sition of organic matter.  Research ideas are as follows:

     1.  Study actual ground water pollution adjacent to areas of
         dead animal or concentrated crop residue disposal to
         determine pollution potential from such sources.

     2.  Evaluate methods of disposal of dead animals, such as
         poultry, so that ground water quality may be protected.
         Methods of disposal may include (a) grinding and disposal
         with manure (b)  grinding and utilization as animal feed,
         and (c) incineration.

     3.  Develop regulatory controls, especially for disposal of
         dead animals by burial underground, so that ground water
         quality may be protected.

PESTICIDE RESIDUES
Continued developments in the various pesticides results in rapid
changes in the water quality effects.  Pesticides of today are in great
variety and application compared with those of even a few years ago.
The future will likely bring even greater changes.  Research ideas are
as follows:
                                  122

-------
     1.  Continued investigation of new and existing varieties
         of pesticides  to determine their ultimate fate in the
         ground and particularly their effect on ground water
         quality.

     2.  Development  of pesticides—insecticides, herbicides,
         and soil fumigants which will not be environmental
         pollutants .

LAND SUBSIDENCE EFFECTS OF VRTER QUALITY

In Section VI, it was reported that land subsidence may be a possible
cause of the occurrence of arsenic in  the ground water.  Research should
be conducted in the areas of land subsidence to determine whether such
a relationship does exist or not.

SEWER LEAKAGE

Many old sewer systems, constructed before the development of satisfac-
tory joint systems, represent potential sources of ground water con-
tamination .  Biological contamination  has not been known to move any
great distance underground,  and pollution of this type would, therefore,
usually be a localized  problem.  Investigation and evaluation of sus-
pected sewers may be  worthwhile in some instances but future control
should likely relate  to the use of leak-proof jointing systems.  No
particular research effort is indicated.

THERMAL POLLUTION
Cooling processes related to electrical  energy generation or any indus-
trial plant may have  an appreciable  effect on ground water temperatures.
Any operation which  has this potential should be carefully evaluated to
determine present and long-range effects on ground water quality.  Re-
search is also  needed to evaluate the effects of elevated ground water
temperatures on the degradation  of various waste products which may
exist underground. Such degradation could have the effect of releasing
toxic substances  to the ground water.

RADIOACTIVITY

Radioactivity,  whether resulting from natural deposits, from mining or
ore processing, or from disposal of  radioactive wastes is a potential
water pollution danger.  Prevention  at the source, rather than correc-
tive research,  would  be the most desirable control.

RECREATIONAL ACTIVITY

Recreational activities are  resulting in serious pollution of surface
waters, and there  is  potential hazard to ground waters in affected areas
Programs to protect surface  waters will  probably correct any ground


                                  123

-------
water problems,  and research aimed particularly at  ground water  quali-
ty is not required at this time.  Monitoring of water  quality in areas
of potential problem should be carried out.
                                  124

                            ACKNOWLE DGEMENTS


Many agencies and individuals have given assistance in the compilation
of reports, publications,  and personal interviews which were used as a
basis for this report.   During the data-gathering phase many hundreds
of reports were  reviewed and many public officials were interviewed in
the four states  included in the project area.

Among the federal agencies, the U.S. Geological  Survey and the U.S.
Bureau of Reclamation have provided much valuable information.  The
Regional Offices of  the U.S. Bureau of Reclamation in Salt Lake City,
Boulder City and Sacramento have provided many reports containing
valuable information.   The District offices  of the U.S. Geological Sur-
vey in Salt Lake City,  Carson City, Palo Alto  and Tucson have provided
a great number of reports, many of which are "open-file" unpublished
reports, which have  been of great assistance in the project.

The various state Water Quality Control offices have been very coopera-
tive and helpful to  us.  Many County and District officers have pro-
vided information which has been invaluable  in the writing of this
report.

Nearly one  hundred individuals, staff members  of the agencies mentioned
above have  provided  cooperative assistance and reference material.  Be-
cause of the great number, no attempt is made  here to give individual
credit, but their cooperation is gratefully  acknowledged.

The authors are  members of the faculty of the Department of  Civil
Engineering at Brigham Young University as well as officers of Fuhriman,
Barton and Associates,  Incorporated; the Contracting Company.  Apprecia-
tion is expressed to colleagues at Brigham Young University  for help-
fulness and cooperation.

The support of the project by the Water Quality office, Environmental
Protection  agency, Les  McMillion, Bruce Maxwell, and Jack Keeley, Pro-
ject officer—all of the Technical Staff at  the Robert S . Kerr Water
Research Laboratory  of  Ada, Oklahoma--are gratefully acknowledged.

             GLOSSARY OF  TERMS,  ABBREVIATIONS AND SYMBOLS


Advanced Waste Treatment  - In sewage, the  additional treatment of
effluent beyond that of secondary treatment, in order to obtain a very
high quality of effluent.  Usually includes nutrient removal.

Alkali zation - The process by which exchangeable sodium accumulated on
the soil colloids and the soil becomes  more alkaline in reaction.

Aquifer - A geologic formation which contains water and has the capa-
bility of transmitting it from one point to another in quantity to
permit economic development.

Artificial Recharge  - The addition of water to the ground-water reser-
voir by activities of man, such as irrigation or induced infiltration
from streams, wells, or  spreading basins.

Beneficial Use of Water  - The use of water for any purpose from which
benefits are derived, such as domestic, irrigation, or industrial
supply, power development, or recreation.

Biochemical Oxygen Demand (B.O.D.) - The quantity of oxygen utilized
primarily in the  biochemical  oxidation  of  organic matter in a
specified time and at a  specified temperature.  The time and temperature
are usually five  days and 20°C.

Brackish Water  - Water  containing dissolved minerals in excess of
acceptable normal municipal,  domestic,  and irrigation standards, but
less than that of sea water .

Cenozoic Age  - Division  of geological history  from the beginning of the
Tertiary  (first period in the Cenozoic  Era) to the present.

cfs - Abbreviation for  cubic  feet per second.

Chemical Water Quality  - Reflects the spectrum and level of concentra-
tion of dissolved chemicals in a water  supply.

Closed Basin  - A  basin  is considered closed with respect to surface
flow if its'topography prevents the occurrence of vxsxble ^tflow   It
is closed hydrologica-ly if neither surface nor underground outflow can
occur.

Confined Aquifer  - An aquifer which is  bounded above and below by forma-
tions of impermeable or  relatively impermeable material.
                                   149

-------
Concentration - The quantity of dissolved materials  in  a  unit volume
or weight of water.  In this report concentration is expressed  in
milligrams per liter, parts per million, equivalents per  million,
specific electrical conductance in micromhos per cm, and  tons per  acre
foot.

Connate Water - Sea water held in the interstices of sedimentary depos-
its and sealed in by the deposition of overlying beds.

Conservative Constituents - Materials carried in the hydrologic system
which, on a class basis, do not interact with the chemical, physical,
or biological elements of the environment to a significant extent.
This classification includes broad groups of materials  such as total
dissolved solids because net conservatism is maintained even though
such interactions as ion exchange take place with the group.

Consumptive Use  (Water) - The sum of the quantity of water used by
vegetative growth in transpiration or building of plant tissue and the
quantity evaporated from adjacent soil or plant surfaces  in a given
specified time.  Also referred to as Evapotranspiration.

Deep Percolation - In a geologic sense, the percolation downward of
water by leakage through the geologic formation.  In hydrology, it is
the percolation downward of water past the lower limit  of the root
zone.

Degradable - Capable of being decomposed, deteriorated, or decayed into
simpler forms with characteristics different from the original.  Also
referred to as biodegradable.

Degradation of Water Quality - Decrease in water quality  due to in-
creased concentration of any substance classified as a  pollutant.

De mineralization - The process of removing the mineral  salts from
water.

Depletion (Ground-Water) - The withdrawal of water from a ground-water
source at a rate greater than its rate of replenishment,  usually over
an extended period of several years.

Dissolved Oxygen - The amount of free (not chemically combined) oxygen
in water.  Usually expressed in milligrams per liter.

Dissolved Solids - Chemicals in true solution.

Drawdown - The magnitude of lowering of the surface of  a  body of water
or of its piezometric surface as a result of withdrawal or the release
of water therefrom.
                                  150

-------
Effluent Stream  - A stream which intersects  the  water  table and re-
ceives flow from ground  water.

Eutrophi cation - The process of overfertilization of a body of water
by nutrients which  produces more organic matter  than the self -purifica-
tion processes can  overcome .

Evapotr an sp ir ation  - See Consumptive Use .

Flood Plain  - Land  bordering a stream and which  receives overbank flow.

Fluvial Sediment -  River or stream sediment  deposits.

                             APPENDIX A

                       WATER QUALITY  STANDARDS
The extent of unde sir ability of  a given level  of  pollution in water is
dependent upon  the  use  or  intended use of the  water .   Standards of
quality of water used for  domestic water supply have  been established
by the National Technical  Advisory Committee on Water Quality Criteria
(238), and the  U.S. Public Health Service (91) .  Tables A-l and A-2,
presented herein, are taken from their reports.

Various agencies have set  standards of quality for waters used for
other purposes. Table  A-3 gives standards foj: livestock watering as
reported by  McGauhey (239) .  Tables A-4» A-5 and  A-6  present irrigation
water quality standards as suggested by the Economic  Research Service
 (240) .  Table A-7 gives standards for water used  in various industrial
processes as reported by the American Society  for Testing Materials
 (241) .

        An investigation  to determine the ground water pollution problems which
   exist in the states  of Arizona, California, Nevada, and Utah was conducted.
   Data were obtained through an extensive review of the literature and through
   interviews with engineers, scientists, and governmental officials concerned
   with water pollution in the four states of the project area.

      Mineralization of ground water is the most prevalent factor in the degradation
   of ground water quality in the project area.  Large quantities of ground water in
   each of the four states are undesirable for many uses because of excessive
   mineralization.  Much  of the mineralization of ground water is a result of
   natural processes.   Some is caused by man's activities—irrigation, oil field
   brine disposal, and  over-pumping of aquifers are common causes of mineralization.
   Usually the degradation is caused by an excess of total dissolved solids, but
   at some locations, specific toxic substances are also found in the ground water.
   Of the various forms of pollution of ground water caused by man's activities,
   nitrate is probably  most prevalent in the project area.

      A listing of conditions causing ground water pollution in the project area is
   included in the report.
