INTRODUCTION The water analyses given in this bulletin have been se- lected from a list of many thousand samples analyzed in the Agri - 1 cultural Experiment Station during the past twenty years. The analyses are being made available in this form to supply the de- mand for information on the quality of irrigation, municipal and domestic water supplies in the state.

The waters are listed alphabetically according to the com- munity or town from which they were sampled. This method of ar- rangement, coupled with a listing according to location within river drainages (Fig. 1), makes the analyses easily accessible either by individual communities or by river drainages.

ANALYTICAL METHODS The waters were analyzed for calcium and Magnesium by titra- tion with a standard soap solution. Chlorides were titrated with a standard silver nitrate solution. Sulfates were determined turbidimetrically after precipitation with barium chloride.

Carbonates and bicarbonates were titrated with standard acid.

Fluorine was determined by the Scott modification of the Sanchis method.Nitrates were determined by the phenol -disulfonic acid method and boron titrated with NaOH in the presence of mannite.

Sodium was calculated by difference. Hardness was calculated as grains per gallon of calcium carbonate from the calcium and mag- nesium content of the waters.The sodium:calcium ratio was calculated by dividing the concentration of sodium by the calcium present.

1. Most of the waters reported here were submitted by well owners, members of the staff of the Experiment Station, the Extension Service, or the Soil Conservation Service. 2 Experiment Station Bulletin No. 225

INTERPRETATION AND SIGNIFICANCE OF ANALYSES Waters which may be considered to be good domestic waters may be very poor irrigation waters, so standards for each are 1 set up separately.According to McGeorge, the following values may be used in classifying domestic waters.

DOMESTIC WATERS Desirable qualities in domestic waters are freedom from taste, freedom from excessive hardness, and freedom from an ex- cessive concentration of fluorine.

Salt content: The presence of 700 to 1000 p.p.m. or more of salt in water makes the water unpalatable and therefore ob- jectionable to taste. For the normal individual there is no harm in drinking water containing 2000 p.p.m. of salts, al- though this is not to be recommended as a permanent practice.

Hardness: Hardness is a quality imparted to waters by the presence of calcium and magnesium. Water which is hard due to calcium combined with bicarbonates can be softened by boiling.

This is called "temporary hardness." When calcium is combined with sulfates, the resulting hardness is known as "permanent hardness." Such waters cannot be softened by boiling. Water which is temporarily or permanently hard may be softened by use of a zeolite softener or by other chemical means. The effi- ciency of some of the new detergents on the market is not affected by the hardness of the water. Degrees of hardness are expressed in the following table:

1. McGeorge, W;T.- Interpretation of Water Analyses. Univer- sity of Arizona, Extension Circular 107. 1940. Chemical Composition of Arizona Waters 3

TABLE 1.Relative Hardness of Waters

Hardness Relative g.p.g. hardness

0.0 - 4.5 Soft 4.5 - 9.0 Fairly hard 9.0 + Hard

Fluorine: The fluorine count of potable waters is very im- portant.Amounts up to 0.8 p.p.m. seem to harden the teeth and make them more resistant to decay. On the other hand, if chil- dren drink water containing möre than 0.8 p.p.m. during the time of formation of their permanent teeth, mottled enamel will result. The severity of mottling is dependent upon the amount present as shown in Table 2:

LE 2. Severity of Mottled Enamel Produced by ..rying Amounts of Fluorine in Drinking Waterl

Amount of fluorine Severity of p.p.m. mottling

0.0- 0.8 None 0.9- 1.3 Mild 1.4- 2.0 Moderate 2.1- 3.0 Moderately severe 3.1or over Severe

Nitrates: In humid regions the presence of nitrates in water is indicative of pollution, but in arid regions their source may be nitrate mineral or from symbiotic or nonsymbiotic nitrogen fixation. It has been suggested that an excess of nitrates in water causes an incidence of "blue babies."This relationship has not been proved in Arizona where, in some in- stances, well waters are used which contain in excess of 300 p.p.m. of nitrates.

IRRIGATION WATERS A good irrigation water, from the standpoint of salt con- tent, is one which is low in salts.It is difficult to classify waters on the basis of salt content alone because the combina- tions of salt which occur are fully as important as the total amount present. Other factors, such as the kind of plant grown and the texture of the soil, must be considered when evaluating the quality of irrigation water. The United States Regional

Salinity Laboratory, Riverside,California) has setup the fol- lowing criteria for quality based on salt content.

TABLE 3. Quality of Irrigation Water

Salt content p.p.m. Quality

0 - 600 Excellent to good 600 - 2000 Good to injurious over 2000 Injurious to unsatisfactory

Calcium, magnesium and sodium: Hard waters are preferred over soft ones for irrigation. To be classed as suitable, waters should contain more calcium and magnesium than sodium.

Such waters have a favorable effect upon the structure of the soil. If sodium predominates over calcium and magnesium, the water will have an adverse physical effect upon the soil. Structure, aeration, and water penetration will be poor and crop growth will be restricted. Table 4 relates the ratio of calcium and magnesium in water to the total bases present as a measure of their quality or suit- ability for use for irrigation.

1. Richards, L.A. The Diagnosis and Improvement of Saline and Alkali Soils. U.S. Regional Salinity Laboratory. 1947. Chemical Composition of Arizona Waters 5

TABLE 4. Quality of Irrigation Water Based on the Ratio of Calcium and Magnesium to Total Bases

Ca + Mg % Na Quality More than 50% Less than 50% Satisfactory 35 - 50% 50 - 65% Doubtful Less than 35% More than 65% Poor

With these values as a guide and knowing the texture of the

soil as well as the crop to be grown, a fair appraisal of the

quality of water may be made. Another method of calculating the quality of water from the

standpoint of sodium and calcium content is to calculate the

sodium:calcium ratio. In this bulletin the ratio is obtained by dividing the amount of sodium in parts per million by the parts

per million of calcium present. A ratio greater than 1.0 indi- cates a preponderance of sodium and therefore an undesirable water. If the soil is well supplied with calcium which slowly becomes available, the sodium:calcium ratio might conceivably be

greater than 1.0 without injury to the soil.

Chlorides and sulfates: An unfavorable salt effect upon the

plant is noted when water containing excessive amounts of

chlorides and sulfates is used for irrigation. Sulfates are

only about half as toxic as chlorides1 on the basis of equiva- lent concentrations expressed in p.p.m., but equally toxic in

equal osmotic concentrations. Table 5 gives the range in concen- tration for these two ions permissible in each of the three

grades of irrigation water.

1. See reference #1 p. 2 and reference #1 p. 4. 6 Experiment Station Bulletin No. 225

TABLE 5. Classification of Waters with Respect to Chloride and Sulfate Content

Concentration p.p.m. Quality

0 -175 chlorides; 0- 350 sulfates Good

179 -290 " ; 350 -600 tt Fair

over 290 " ; over 600 " Poor

Bicarbonates and carbonates: Bicarbonates are less toxic than chlorides or sulfates.The chief difficulty of using bi- carbonate waters for irrigation lies in the fact that if carbon dioxide and water are lost, there is a conversion to the toxic normal carbonate. The presence of carbonates is an indi- cation of the so- called "black alkali" in the water.

Nitrates: Many Arizona waters carry relatively high con- centrations of nitrates. When these waters are used for irri- gation it is likely that the nitrogen which they contain is utilized by crops. If a water contains 10 p.p.m. of nitrogen in the form of nitrate, each acre -foot of water applied will add the equivalent of 128 pounds of ammonium sulfate to each acre of soil.

Boron: It has been shown that boron is an essential plant food element. However, if the concentration becomes too great, toxicity occurs. The amount of boron permitted in irrigation water depends upon the tolerance of the crop to which it is sup- plied. Citrus shows toxicity symptoms when irrigated with water containing 0.5 p.p.m. of boron, but alfalfa does not show these symptoms until a concentration of about 3.0 p.p.m. of boron is reached. There are very few waters in Arizona which contain excessive concentrations of boron.1

DRAINAGE AREAS

Arizona has primarily twb drainage areas. The first and smallest drains the lower Sulfur Spring Valley through the White - water. draw. to the Yaqui river of Mexico. The upper Sulfur

Spring Valley drains into the Willcox playa, a large alkali

basin without outlet, near the town of Willcox. The rest of the

state is drained by the and its tributaries.

THE SULFUR SPRING VALLEY

The Sulfur Spring Valley extends northwest from Douglas,

which is on the international boundary between Arizona and

Mexico, to a point several miles north of Willcox, a distance of

approximately 75 miles. The Valley, which averages about 20 miles in width, is bordered on both east and west by mountains

which contribute water to the underground supply. Most of the irrigation is done on lands where groundwater can be found within

100 feet of the surface. Since 1940 when Rural Electrification power became available, there has been a great increase in the

amount of underground water pumped in the Valley. Some of the

wells in the Willcox basin are artesian. Most of the wells, ex- cept those close to the playa, are satisfactory for irrigation

purposes, since as a rule they contain less than 1000 p.p.m. of

salts, are relatively hard, and have a Na:Ca ratio of less than

1.0. When considered from the domestic point of view, some of the waters are hard while others contain excessive amounts of

fluorine. The waters in the Whitewater drainage area are similar in

character to those in the Willcox basin. Most are satisfactorily

low in salts, some have excessive amounts of fluorine, and

others have excessively high Na:Ca ratios.Fluorine concentra- tions seem to occur close to the rather than in

the valley fill at a distance from the draw. Experiment Station Bulletin No. 225

COLORADO RIVER DRAINAGE Gila Valley: This valley is' naturally divided into three parts. The upper Gila extends from the headwaters to the San

Carlos Dam site. The middle Gila extends from the San Carlos ]am to the Gillespie Dam; andthelower Gila from Gillespie Dam to the Colorado river. Since most of the side streams entering the now have dams constructed in them, there is less water in the main stream thanformerlyand fewer floods. Debris in the channel in the upper Gila diverted water,which caused disastrous floods at Duncan in 1941. Water seldom flows in the main channel of the lower Gila, but in 1940 heavy rains in the upper watershed caused floods to spreadwidely over the bottom lands. The channel in some places is poorly defined, and in others choked with a heavy growth of salt cedar. Both factors contribute to the spreading of the water. Agriculturalcenters in the upper Gila Valley include, among others, Franklin, Duncan,Solomonville, Safford, Thatcher, Central, Pima, Glenbar, Ashurst, and Ft. Thomas. Some of the water used for irrigation is diverted from the Gilariver while some is pumped from wells or flowsby artesian pressure. River water is of variable quality, depending upon its sourceand the season of the year. Most well waters are excessivelyhighin salts and have a high Na :Ca ratio, so their qualityis generally regarded as poor for either domestic or irrigation purposes. In addition, the majority of the waterscontainexcessive concen- trations of fluorine. The city of Safford and adjoining com- munities have a very satisfactory water supply,obtained by developing springs in Bonita Canyon andinstalling aninfiltra- tion gallery to collect the water.

Some of the communities in the middle Gila area areHayden,

Winkleman, Kelvin, Florence, Coolidge, Sacaton, Komatke, Chemical Composition of Arizona Waters 9

Laveen, Liberty, Buckeye, Palo Verde, Hassayampa, and Arlington.

There is some blending of waters with a consequent change in quality where streams such as the San Pedro, Salt or Hassayampa rivers and the Gila river converge. In general the salt con- tent of the underground waters is lower in the middle Gila

Valley than in the upper Gila Valley.As a rule, the upper Gila waters are hard, have an unfavorable Na:Ca ratio, and contain toxic concentrations of fluorine.

Gila Bend, Roll, Wellton, and the north and south Gila districts are the more populated areas in the lower Gila area.

The waters in this area as a general rule are high in soluble salts; they are very hard, have a high Na:Ca ratio and an exces- sive amount of fluorine. The salts in the well water used for irrigation in the Roll district are so high that only the most tolerant crops can be grown. A large increase in acreage farmed in this area is expected when Colorado river waters replace the present pump supply.

Tributaries of the Gila: The Blue and San Francisco rivers drain the mountainous country near Clifton. Because of the na- ture of the country drained by these streams, the salt content of the waters is low. joins the Gila river from the north a few miles below Clifton.

The San Simon Valley is drained by the San Simon creek.

The creek has its origin near Portal at the northeast side of the Chiricahua Mountains and flows into the Gila near Solomon - ville. San Simon and Bowie are the two largest settlements in the area. The waters in the vicinity of Bowie are soft, have a low soluble salt content and a low fluorine content. In the vicinity of San Simon the waters are uniformly low in salt, have a high sodium:calcium ratio and a high fluorine content. 10 Experiment Station Bulletin No. 225

The San Carlos river flows into the San Carlos reservoir and for a distance forms the northern arm of the San Carlos reservoir. No water samples have been collected from this area.

The San Pedro river is an important tributary to the Gila river. It rises in Cochise county and flows northward through

Lewis Springs, Fairbanks, Benson, St. David, Cascabel, Mammoth,

Feldman, and Winkleman. No permanent diversions for water have been built so the irrigated agriculture is not on a sound basis, since the temporary diversions wash out in each period of high water. The waters in this valley are especially low in soluble salts; they are soft, but usually contain excessive amounts of fluorine. It was at St. David where the relationship between fluorine and mottled enamel' was discovered. It is interesting to note that the waters at Benson and St. David are both artes5an

in nature, yet the Benson water is relatively free from fluorine while the St. David waters are so high in fluorine as to cause

severe mottled enamel. The St. David school has the distinc- tion of being the first school in the United States to install a bone filter2 for the removal of fluorine from their drinking water. The Ajo school has the first filter capable of being regenerated in place. An investigation at Pomerene has shown

shallow wells to be relatively free from fluorine while the deep wells contain high concentrations. The Aravaipa is a tributary of the San Pedro and drains the territory in western Graham county. The waters here are

Chemical Composition of Arizona Waters 11 extremely low in salts, are low in fluorine, and have a satis- factory Na:Ca ratio.

Salt River and its tributaries:From the standpoint of population density this area is the most important in the state.

Large urban, suburban, and rural populations are supported here.

The is the result of the union of the White and Black rivers, both of which rise in the White Mountains. Roosevelt

Dam, which was built on the stream just below the point where

Tonto Creek joins it, impounds water for the highly successful

Salt River Valley Project. The quality of water in the Salt river is good, as is that of the Verde which joins the Salt above Granite Reef Dam. The amount of gravity water available from the Salt river is not sufficient to meet the requirements of the project, so this supply is supplemented with groundwater pumped from various wells throughout the valley. The quality of the pumped water is not as good as the gravity water, but by skillful blending of the two, water of good quality is supplied to all parts of the project.These irrigation wells serve also as drainage wells. In the lower parts of the valley, these wells have lowered excessively high water tables as well as reduced the salinity of the soil. Phoenix, the state capital, is the largest city in the area.

It secures water by means of an infiltration gallery in the , three wells at Scottsdale, and four wells in the Phoenix city limits. Some of the suburban area near Phoenix is also provided with this supply, although most generally small, privately -owned water utilities serve the outlying districts.

The Verde river supply is quite satisfactory for domestic uses since it is low in soluble salts and fluorides. Its chief drawback is its hardness. Other towns and cities in the Salt River Valley have their own local water supplies. By tapping 12 Experiment Station Bulletin No. 225

1 the lower water strata, most of these towns have avoided the upper strata which is often dangerously high in fluorine. The underground water in the New and drainages, as

judged from analyses of water at Peoria and Marinette, is of good quality for domestic and irrigation purposes. It is low in total salts and fluorine. It is classed as hard, so would be less desirable than a softer water for domestic purposes. Some

of the waters have an unfavorable Na:Ca ratio when considered from the standpoint of use for irrigation. The Upper Verde drainage area in the vicinity of Chino Valley produces waters which are low in total salts and low in fluorine. They have a favorable Na:Ca ratio and are somewhat softer than the water at Cottonwood or at Phoenix.

Hassayampa: The quality of the water in the Hassayampa drainage as judged from waters in the vicinity of Hassayampa and

Wickenburg is generally good. The salt content is satisfactory for either domestic purposes or irrigation. Most of the waters are classed as hard, although many of them have an unfavorable

Na:Ca ratio. A few of the waters are high in fluorine. The Santa Cruz river drains parts of Santa Cruz county,

Pima county, and Maricopa county. The channel between Casa Grande and Komatke, near which it enters the Gila river, is in-

distinct. For the most part, water which enters the river south of Tucson never reaches the Gila, but spreads over the desert in

the vicinity of Eloy and Casa Grande. Its most important tributaries are Rillito Creek, Canon del

Oro, and Brawley Wash. The city of Nogales takes its water from the Santa Cruz river by means of an infiltration gallery, while the city of Tucson taps its underground flow by means of a

Part of the Tucson supply is pumped from deep wells in the eastern part of the city and is distinctly different in quality from the Sante. Cruz underflow.

Water of widely varying quality occurs in the Santa Cruz drainage. For example, south -side city water at Tucson probably averages over 600 p.p.m. of total salts, whereas most of the north -side city wells contain less than 400 p.p.m. of total salts. The south -side waters contain about 0.9 p.p.m. of fluorine and cause very mild mottled enamel, while the north - side or Rincon water contains only 0.3 p.p.m. of fluorine. One well south of Tucson (Lab. No. 49619) produces water which does not follow the usual pattern with respect to salt content as do most others in the Santa Cruz drainage. It has a total salt con- tent of 3609 p.p.m. and a hardness of 60.6 grains per gallon.

Moderate amounts of fluorine are found in the vicinity of San Xavier, while heavier concentrations are found at Tanque Verde and Wrightstown. Most of the waters in the Santa Cruz basin are excellent for irrigation because of their generally low salt content and favorable da:Ca ratio. Some of the waters have an unfavorable

Na :Ca ratio, and a few should be used with caution because of their high salt content.

The : The Little Colorado river rises in the White Mountains and flows northeastward through

Springerville, St. Johns, Woodruff, Holbrook, Winslow, and

Leupp to Cameron. It empties into the Colorado river about 30 miles northwest of Cameron.The main tributaries are the Carrizo Creek, , , , Leroux

Wash, Cottonwood Wash, , Clear Creek, Canyon

Diabolo, Palacco Wash, San francisco Wash, Dinnebito Wash, and 14 Experiment Station Bulletin No. 225

Moenkopie Wash. Silver Creek and the upper reaches of the Little Colorado river drain wooded mountains and therefore are low in salts.

After union with the Zuni river, the higher salt content of the

Zuni is reflected in the Little Colorado. Since the Zuni river drains certain shale badlands, in flood it carries a large amount of clay in suspension.

The Colorado river: The Colorado river enters Arizona from about 75 miles east of Fredonia and flows generally in a south- westerly direction through the Grand Canyon to the Nevada state

line. It forms the boundary between Arizona and Nevada and between Arizona and California.Hoover Dam at Boulder City forms , which is an important source of irrigation

water and power. Davis Dam forms Havasu Lake which stores water for the Metropolitan Water District of California. Imperial

Dam, north of Yuma, diverts irrigation water into the All

American Canal for use in both Arizona and California. Yuma is the only city in Arizona which uses Colorado river

water for domestic purposes.
