QUALITY OF SURFACE WATERS

FOR IRRIGATION, 

WESTERN STATES, 1959

INTRODUCTION

The records of chemical analyses, other physical measurements, and discharge given in this report comprise the ninth annual compilation of data for 67 irrigation network stations in operation west of the Mississippi River.

Geological Survey Water Supply Papers 1264 and 1362, the annual compilations for water years 1951 and 1952, respectively, 

describe briefly the development of this series of reports. In 

summary, there is an expressed need for comprehensive continuing information about the chemical quality of surface waters used 

for irrigation and the changes resulting from the drainage of irrigated lands.

In recognition of this problem the Subcommittee on Hydrology, 

Interagency Committee on Water Resources (formerly the Federal 

Interagency River Basin Committee) on February 6, 1950,approved 

a list of 106 network stations on streams in Western United States 

at which water samples were to be collected and analyzed with 

particular reference to the use of these streams waters for irrigation. These stations, with pertinent information about periods 

of operation, are shown in the following table. Of the 106 stations 

selected, 39 were already being operated by the Geological Survey 

and 7 by the International Boundary and Water Commission. From 

the remaining stations on the list, 30 were selected for activation 

by the U. S. Geological Survey during the fiscal year 1951. In 

addition, 3 stations previously operated in connection with other 

programs and scheduled to be discontinued were to be included in 

the list to be operated by the Geological Survey (the subcommittee 

amended the list on October 2, 1952, to include the three additional stations, bringing the recommended number of irrigation 

network stations to a total of 109).

It was contemplated that the network stations would be located 

at streamflow gaging stations and that the program of collecting 

and analyzing the samples and reporting the findings would be the

INTRODUCTION 5

responsibility of the Geological Survey. The scope of the chemical analyses would provide for the calculation of the salt burden 

of stream and in general would conform with the current Geological Survey standards for the comprehensive investigation of the 

chemical quality of surface waters.

The following criteria were recommended in the selection of 

the key network stations.

1. All recommended stations should be located on streams 

west of the main stem of the Mississippi River.

2. All proposed stations should relate primarily to irrigation 

although multiple-purpose needs which include irrigation may be 

considered.

3. All stations should be located at or near streamflow gaging 

stations. The most nearly up-to-date list of gaging stations currently operated by the U.S. Geological Survey (which comprises 

all but a small percentage of all gaging stations) will be found in 

the most recently published Geological Survey water-supply papers 

for the areas involved.

4. Consideration should be given to the location of irrigation 

development areas that are now affecting or are likely to affect 

the chemical quality of the river water.

5. Only those stations should be proposed that are likely to 

reflect important changes in chemical quality over a period of 

years. Stations operated for relatively short periods (5 years or 

less), as would be required for intensive studies of specific projects, should not in general be included.

Plate 1 is a plot of the recommended list of 109 network stations on streams in Western United States. The 67 stations in 

operation in 1959 are identified by a solid circle. The period of 

record, in years, is also shown at each of these stations. In a 

few instances the period of record differs from that obtained from 

the date established by the Subcommittee, as earlier records were 

included also. Proposed stations are identified by an opencircle.

To facilitate identification, each Geological Survey gaging station and sampling station has been assigned a station number. 

The station numbers were assigned according to Geological Survey practice in reporting records of streamf low: Stations on tributary streams are listed between stations on the main stem in the 

order in which those tributaries enter the main stem. However, 

in this report the numbers will not all appear in increasing numerical order because all the main stem stations on a river are 

reported before listing the stations on the tributaries.
6 QUALITY FOR IRRIGATION, 1959

The complete number for each station has eight digits, but the 

station number as shown in this report just to the left of the station name consists of only the digits essential for identification. 

For example, for a station with the complete number 04-0100.00, 

this station number shown in this report is 4-100.

At the end of the 1958 water year, nine stations were discontinued; Missouri River at Pierre, S. Dak., Yellowstone River at 

Billings, Mont., North Platte River below Guernsey Reservoir, 

Wyo., Republican River above Medicine Creek, at Cambridge, 

Nebr., Little Colorado River at Cameron, Ariz., Agua Fria River 

below Lake Pleasant Dam, Ariz., Columbia River at Grand Coulee 

Dam, Wash., Snake River at Central Ferry, nearPomeroy, Wash., 

and Rogue River at Grants Pass, Oreg. Operations were suspended at seven stations. Humboldt River at Rye Patch, Nev., 

and the six stations in California. The station at Rye Patch, Nev., 

is expected to resume operation in the 1960 water year.

Two of the six stations in California resumed operations December 1958; San Joaquin River near Vernalis, and Sacramento 

River at Knights Landing. Although the data at these two stations 

represented less than 70 percent of the discharge for the 1959 

water year, these data are published in order to give a more representative account of conditions of the quality of water for irrigation in the western states.

Agencies that have each contributed to some part of the data 

published herein include: The Agriculture Research Service, and 

the Soil Conservation Service, U.S. Department of Agriculture;

During 1958-59, the United States Section of the International 

Boundary and Water Commission operated the stream gaging stations for the following Rio Grande stations included in this report: 

El Paso, Fort Quitman, Upper Presidio, Langtry, Falcon Dam

also. The Mexican Section operated the stream gaging station on

the main stem at Laredo. Each section operated the gaging stations on the tributary streams, floodways, and diversions within 

its own country.

Descriptive headings and discharge data for the seven stations 

operated by the International Boundary and Water Commission, 

were obtained from Water Bulletins 28 and 29 prepared jointly by 

the United States and Mexican Sections of the International Boundary and Water Commission. These publications contain stream 

discharge and related data for 1958 and 1959. Analyses for seven 

Rio Grande main stem stations and for the Pecos River near 

Shumla, Tex., were obtained from the U. S. Salinity Laboratory, 

Riverside, Calif.

Additional contributions of data have been made by individuals, 

corporations and other State and Federal agencies, and their cooperation is acknowledged with appreciation.

COLLECTION OF SAMPLES

In accordance with the recommendation of the Subcommittee, 

where practicable, one sample was collected each day throughout 

the water year. In general, each sample was taken in an 8- or 

12- ounce glass bottle provided with a pressure-type or positiveseal closure to prevent escape of dissolved gases. Each sample 

was integrated in the vertical section of a stream usually at about 

midpoint of flow by lowering the open sample bottle to the bottom 

and returning it to the surface during the filling process.

At most stations the samples were collected by local residents 

hired for the purpose. The local sample collector recorded on 

each bottle the name of the stream, location, gage height (if practicable), water temperature, time of day, date, and collector's 

name or initials. Samples were shipped to the laboratory or 

picked up by technical personnel on a predetermined schedule. 

Visits were made periodically by technical personnel to check on 

sampling procedures.

EXAMINATION OF SAMPLES

Upon receipt of samples in the laboratory, they were recorded 

and stored away from direct sunlight until opened for analysis. 

Specific conductance was deter mined with a conductance bridge on 

each sample as sooa as opened. These data provided a basis for 

compositing a series of daily samples, for complete analysis. 

In general, a minimum of three composites a month consisting of
8 QUALITY FOR IRRIGATION. 1959

equal volumes of approximately 10 daily samples, were prepared 

for chemical analysis. Individual samples that showed differences 

in conductance of more than 30 percent of the mean for the period 

were not included in the composite, but were grouped separately 

for additional conposite samples or analysis of the individual 

sample was made. For those stations where acceptable discharge 

values were reported with the samples or could be obtained 

promptly from rating tables, samples were prepared by mixing 

volumes of individual samples in proportion to water discharge.

The following series of 15 determinations (schedule 1) were made 

on all composite samples for all new network stations during the 

first year of operation: Silica, iron, calcium, magnesium, sodium, 

potassium, bicarbonate, carbonate, sulfate, chloride, fluoride, 

nitrate, boron, dissolved solids, and specific conductance. The 

following values were calculated from the analytical data: Dissolved solids in tons per acre-foot, dissolved solids in total tons, 

total hardness, noncarbonate hardness, and percent sodium.

It was further recommended by the Subcommittee that during 

the second and third years the following series of 11 determinations (schedule 2) would be made on all composite samples: Calcium, magnesium, sodium, bicarbonate, carbonate, sulfate, chloride, nitrate, boron, dissolved solids, and specific conductance. 

Hardness, noncarbonate hardness, percent sodium, total tons and 

tons per-acre-foot would be calculated as in schedule 1.

In the fourth and succeeding years (unless significant changes 

become apparent) it was recommended that the following determinations (schedule 3) would be made on all composite samples 

as long as the program is in effect: Calcium and magnesium 

(either separately, or together by the recently developed ethylenediamine tetraacetic acid titration test for hardness), sodium dissolved solids, and specific conductance. In addition, four complete analyses (schedule 1) would be made each year, one analysis 

to be made on a composite sample during each quarter. Certain 

additional determinations above these minimum requirements were 

to be made if deemed necessary to define widely varying characteristics of the stream water.

All laboratory determinations were to be made in accordance 

with standard procedures used by the Geological Survey. These 

procedures are based on methods found in authoritative publications on water analysis.

REPORTING OF DATA

In order to release the data in the form most widely used in the 

evaluation of irrigation waters, the results of analyses in this 

compilation are given in equivalents per million, rather than the 

conventional unit part per million. Some agencies that actively 

participate in irrigation water-quality investigations prefer to 

express results in milligrams per liter (mg/1) and milliequivalents per liter (meqA)- However, for all practical purposes 

where concentrations of dissolved solids are less than about 7,000 

parts per million, no correction for density of the water is necessary and the units reported in each method are considered to be 

synonymous.

If results are desired in parts per million they can be calculated 

by multiplying the reported values in equivalents per million by 

the chemical combining weights of the individual constituents. 

Pertinent physical data and water discharge are also included in 

the tables.

EXPLANATION OF TABLES

The tables of analyses beginning on page 22 include a brief descriptive heading summarizing the more pertinent features at each 

station as follows:

Location of Station is given generally as the distance in land or 

river miles from a town or other political or geographic feature. 

In Survey practice the term "at" generally implies that the station 

is within a mile radius of the named town whereas "near" implies 

that it is beyond a mile radius.

Drainage area above the gaging station was obtained from the 

most recent published records of the annual reports of the Geological Survey on Surface Water of the United States, andfrom International Boundary and Water Commission.

Records available are given for all periods during which samples, 

other than infrequent, were collected for chemical analyses. It 

does not include the periods for which discharge records are 

available.

Extremes for the current year and for the period of record are 

reported for specific conductance and percent sodium because of 

their widespread application in the evaluation of analyses of water 

used for irrigation. The results for specific conductance are

708-297 O-63-2
10 QUALITY FOR IRRIGATION. 1959

based on the measurement made at the laboratory upon receipt of 

the sample from the field. Data for percent sodium were obtained 

from composite-samples analysis.

Remarks include sources of data, additional explanation concerning the records, and offices where the records of chemical 

quality may be obtained.

Discharge of records were obtained from the responsible Geological Survey Surface Water Branch offices except for the seven 

stations operated by the International Boundary and Water Commission. Discharge data are shown in acre-feet, calculated from 

the mean daily discharge in cubic feet per second by multiplying 

by the factor 1.983.

Analytical values are reported in equivalents per million for cations and anions. The equivalent is the weight with reference to 

some standard (such as the combining weight either of oxygen, 

8, or of hydrogen, 1.008) of that quantity of an element, radical, 

or compound to complete a definite chemical reaction. An equivalent of an element or ion is exactly equal in combining power to 

one equivalent of another element or ion. As previously discussed, for concentrations of dissolved solids that are normally 

encountered in water for irrigation, an equivalent per million is 

equal to a milliequivalent per liter. Silica, which is considered 

to be present in the colloidal state, and boron, are reported in 

parts per million. Percent sodium is calculated as follows:

Na x 100 where all constituents are reported in equivalents 

Na+K+Ca+Mg 

per million.

At the recommendation of the Subcommittee, sodium-adsorptionratio (SAR) is published for all network stations beginning October 1952. The term is defined and described under "Sodium 

hazard" on page 20.

cover was substantial during the winter months, runoff was minimal because the snow melted gradually and was absorbed into the 

soil.

Runoff for Sheyenne River at Warwick was 50 per cent lower than 

in the previous year, and the dissolved-solids content of the water 

decreased by 15 percent.

Runoff for Souris River near Westhope was 70 percent lower 

than in the previous year, and the dissolved-solids content of the 

water increased by 19 percent. The percent sodium was 49 the 

highest of the 5 years of record.

MISSOURI RIVER BASIN

Missouri River main stem. The Missouri River is regulated by the 

following dams: Canyon Ferry and Fort Peck, upstream from 

Williston, N. Dak.; Garrison, Oahe, Fort Randall, and Gavins 

Point (Lewis and Clark Lake), between Williston, N. Dak., and 

Nebraska City, Nebr.

Total amount of water in storage in the main-stem reservoirs 

on September 30, 1959, was about 25,900,000 acre-feet, an increase of about 2, 760,000 acre-feet over the previous year. Currently, water from all reservoirs is used for power generation, 

flood control, pollution control, municipal supply, navigation, and 

recreation. Also, water from Canyon Ferry Reservoir is used 

for irrigation; eventually, water from other reservoirs will be 

used for irrigation.

Upstream from Fort Peck Reservoir, Mont., runoff was about 

15 percent above the annual aver age, and precipitation was slightly 

above the long-term mean. At Williston, N. Dak., runoff increased 

by 10 percent over the previous year and the dissolved-solids content decreased. Streams in North and South Dakota contributed 

little runoff to the main-stem flow because of drought conditions 

that prevailed during the year. At Nebraska City, Nebr., runoff 

was about the same as that in the 1958 water year, and the dissolved-solids content increased slightly.

The discharge-weighted aver age of dissolved solids for the 1959 

water year was about the same as that for previous years. Average dissolved-solids content at Williston was 405 ppm compared 

with 415 ppm and at Nebraska City was 433 ppm compared with 

432 ppm for the 9-year period 1951-59.

Yellow stone River basin. Runoff from the Yellow stone River basin 

in Montana was slightly more in 1959 than in 1958, but it was considerably less than in 1957 and less than the long-term average. 

Runoff for Yellowstone River at Billings and Tongue River at
14 QUALITY FOR IRRIGATION, 1959

Miles City was above the average. The weighted average of dissolved-solids content increased over those for 1957 and 1958 for 

the Bighorn and Tongue Rivers but deer eased for the Powder River 

and for Yellowstone River near Sidney. Despite the decrease at 

the Sidney station, the weighted average of dissolved-solids content for 1959 was slightly above the 9-year average. The sodiumadsorption-ratio was about average for all sampling stations.

The concentrations of dissolved solids at Sidney was equal to 

the 9-year average, although it was considerably less than that 

for 1957 and slightly less than that for 1958. The Bighorn River 

contributed 48 percent of the concentration at Sidney compared 

with 54 percent in 1958 and 52 percent in 1957. The Tongue and 

Powder Rivers contributed 4 and 9 percent, respectively; in 1958 

these streams contributed 3 and 10 percent. Yellowstone River 

at Billings was discontinued September 30,1958; however, 8 years 

of past record indicate that the average annual contribution of 

dissolved-solids content from the Yellowstone River upstream 

from Billings was about 29 percent of that at Sidney.

No significant changes in impoundment or diversions were made 

during the year. About 5,000 acres of new land was brought under 

irrigation in the Bighorn River basin during 1959. There were no 

variations in methodology from that proposed for irrigation network stations.

James River basin . Severe drought conditions existed in the 

James River basin in South Dakota during the year. Almost no 

flow was recorded during the entire water year at the gaging station at Huron; runoff for 1959 was 367 acre-feet compared with 

the 20-year average of 151,300 acre-feet. Samples for chemical 

analyses were collected upstream from the gage and the diversion.

Platte River basin. Precipitation in the North Platte River basin 

was greater during 1959 than during 1958. Runoff at the gaging 

stationbelow Guernsey Reservoir was less than in 1958 and about 

30 percent below the long-term average. The sampling station 

below Guernsey Reservoir was discontinued September 30, 1958; 

therefore, no data on chemical quality are available for 1959.

Streamflow in the South Platte River was near normal most of 

the year. Runoff at Julesburg, Colo., was near average for the 

period 1951-59, although it was 62 percent less in 1959 than in 

1958. The dissolved-solids content increased, but the percentage 

composition remained about the same as the previous year. The 

average dissolved-solids content was 1,370 ppm compared with 

the 9-year discharge-weighted average of 1,210 ppm.

Downstream from the confluence of the North Platte and South 

Platte Rivers, the degree of concentration depends on the proportional amount of flow enter ing from these rivers. Water from the
DISCUSSION OF RESULTS 15

North Platte River is less concentrated than water from the South 

Platte River. Both runoff and dissolved-solids concentration decreased from the previous year at the stations Platte River at 

Brady, Nebr., and Supply Canal near Maxwell, Nebr.

LOWER MISSISSIPPI RIVER BASIN

Arkansas River basin . Runoff in the Arkansas River basin above 

John Martin Reservoir was much lower than for the preceding two 

year period. The lower runoff is reflected in the quality of water 

released from the reservoir by an increase in salinity at Arkansas 

River below John Martin Dam, Colo.

Streamflow at four irrigation network stations was less during 

the 1959 water year than during the 1958 water year. The annual 

discharges in the Arkansas River stations at Arkansas City,Kans., 

and Ralston, Okla., were approximately 50 percent less than the 

1958 values. The decrease in discharge at Arkansas City amounted 

to slightly more than 1 million acre-feet, and at the Ralston station the decrease was about 2 million acre-feet. The Cimarron 

River at Per kins showed a drop in streamflow of some 184,000 

acre-feet, or about 17 percent less than in 1958. The annual discharge of the Canadian River at Whitefield during 1959 was about 

33 percent less than 1958, a decrease of some 1,000,000 acrefeet.

The reduced streamflow in the Arkansas River resulted in an 

increase in the dissolved-solids content in the water at both irrigation stations. The weighted average dissolved-solids content at 

Arkansas City increased from 707 ppm in 1958 to 967 ppm in 

1959. At the Ralston station, the dissolved-solids content increased from 741 ppm in 1958 to 812 ppm in 1959.

In contrast, the lower discharges recorded at the Cimarron and 

Canadian River stations during the 1959 water year resulted in 

decreased weighted average dissolved-solids concentrations. At 

Per kins the dissolved-solids content in the Cimarron River dropped 

from 3, 530 ppm in 1958 to 3,250 ppm in 1959. This decrease in 

dissolved-solids content was the result of lower runoff from the 

basin draining the "Salt Plains" of Oklahoma.

The weighted average dissolved-solids content in the Canadian 

River at the Whitefield station was 416 ppm in 1959 as compared 

to 512 ppm in 1958. This decrease in dissolved solids was a result of a decrease in the proportionate amount of water contributed to the Canadian River by the North Canadian and Little Rivers 

during 1959. These two tributaries in the lower part of the Canadian River basin contribute the major portion of the annual dissolved-solids load to the Canadian River.
16 QUALITY FOR IRRIGATION, 1959

Red River basin . Runoff of the Red River at Denison Dam near 

Denison, Tex., during the 1959 water year was only 44 percent of 

the long-time average, and the weighted average of dissolvedsolids content, 1. 50 tons per acre-foot, was the highest since 1944.

WESTERN GULF OF MEXICO BASINS

From the Sabine to the Nueces River, in the Western Gulf of 

Mexico basins, the 1959 weighted average dissolved-solids content of all stations increased slightly over 1957 and 1958 levels. 

Runoff was considerably less than for 1957 and 1958, and was below the long-term averages except at Victoria where the flow of

Colorado River basin. Runoff in the Colorado River basin shows 

a decrease from the previous year, and a more or less corresponding increase in salinity.

Rio Grande basin . Runoff in the Rio Grande basin in New Mexico 

was less than that of the preceding two years. This was reflectee" 

by a gener ally higher dissolved-solids content in the surf ace water. 

However, the effect of the lower runoff was not so conspicuous ir 

in the Rio Grande at Otowi Bridge, near San Ildefonso due to the 

low flow and delivery of the saline-type water from the San Luir 

Valley. The effect of the lower flow upon the quality of water of 

the two stations on the Rio Grande near San Marcial was also 

slight because two major tributaries (Rio Puerco and Rio Salado) 

which ordinarily contribute water of poor quality to these stations 

had a low storm runoff.

Runoff at the station, Pecos River below Red Bluff Dam, near 

Orla, Tex., was only 34 percent of the 22-year average but war 

15 percent greater than in 1958. Weighted aver age dissolved-solidr 

concentration decreased from 8.02 tons per acre-foot in 1958 to 

6. 99 in 1959. Storage in Red Bluff Reservoir decreased during 

the year to 60,000 acre-feet, only about 20 percent of capacity.

COLORADO RIVER BASIN

Colorado River main stem . Runoff continued to decrease in the 

upper Color ado River basin for the second consecutive year. Flow 

was less than that of the previous year throughout the basin and 

approximately 50 percent of long term average for the station at 

Cisco.

The percentage composition for the weighted average analysis 

remained relatively unchanged for the stations at Glenwood 

Springs, Colo., and Cisco, Utah, although the dissolved-solids
DISCUSSION OF RESULTS 17

content increased by 21 percent and 50 percent respectively. Dissolved-solids content has nearly doubled at the Cisco station since 

the 1957 water year. Total loads for both stations were considerably lower than those of the preceding year.

Little or no variation was observed in the quality of the water 

at the station below Hoover Dam. Both the discharge and total 

dissolved solids load passing the station were 20 percent less than 

that reported the preceding year.

Gunnison River basin . Total dissolved-solids load for the Gunnison River basin decreased by 32 percent as compared to the 

1958 water year. A decrease of 60 percent in runoff was reflected by a 69 percent increase in dissolved-solids content. 

Weighted average dissolved-solids content has increased by slightly 

more than 100 percentsince 1957. The total loadforthe Gunnison 

River was approximately 30 percent of that recorded at Cisco.

Green River basin. An increase of 8 percent in weighted average dissolved-solids and tons per acre-foot was noted at the Green 

River, Utah station, probably as the result of a continued decrease 

in runoff in the Green River basin. Percent sodium and SAR increased slightly as compared with the preceding year.

San Juan River basin . The runoff for the San Juan River at Bluff, 

Utah for the 1959 water year was 75 percent less than that of the 

previous year. Total loads decreased by 58 percent. The decrease in runoff was reflected by an increase of 72 percent in the 

weighted average of dissolved-solids content. The weighted average analysis indicated that the percentage composition of the 

water remained relatively unchanged. Sodium content continued 

to be high during periods of low flow.

Virgin River basin. Runoff for the Virgin River at Littlefield, 

Ariz., decreased by 68 percent as compared to the previous years 

flow. A decrease of 48 percent in total load was observed for this 

station although the dissolved-solids content increased 65 percent. There was little or no change in the percentage composition 

of the water.

Gila River basin . The annual runoff in the Gila River at Kelvin, 

Ariz., was much greater than that of the preceding year, but the 

water quality of the runoff was relatively the same since this river 

was not affected by upstream storage and storm runoff.
18 QUALITY FOR IRRIGATION, 1959

THE GREAT BASIN

Sevier River basin . The chemical characteristics of the water 

and the percent sodium remained relatively unchanged for the 

Sevier River at Lynndyl,Utah. The weighted average of dissolved 

solids increased by 10 percent because of a 15 percent of runoff.

Humboldt River basin. The station for the Humboldt River near 

Rye Patch, Nev., was not in operation for the period Oct. 1, 1958 

to Sept. 30, 1959. Station operations are to be resumed at the 

beginning of the 1960 water year.

PACIFIC SLOPE BASINS IN CALIFORNIA

Since only two of the six stations in California were in operation for part of the 1959 water year, the chemical data are incomplete. As a consequence, these data must be regarded as 

pertaining only to that part of the basin where the station is located and not having basin-wide application.

San Joaquin River basin . Runoff of the San Joaquin River near 

Vernalis was approximately 20 percent less than the previous 

year and 35 percent less than the long-term average for the station. Although samples were not collected during the first two 

months of the water year which was 31 percent of the runoff, 

weighted averages were based on the flow for the entire water 

year.

Chemical quality of the outflow declined rather markedly the 

weighted dissolved-solids load increased from 0. 21 to 0. 48 tonr 

per acre-foot and average specific conductance increased. Because of impoundment of water and extensive irrigation in the 

San Joaquin Valley, the San Joaquin River channel at times carrier 

mainly irrigation-return water of poor quality.

Sacramento River basin. Runoff of the Sacramento River at 

Knights Landing was approximately 60 percent less than the previous year and slightly greater than the 1957 water year. Sampler 

were not collected during the first two months of the water year 

and weighted averages were not determined for this station.

Although the discharge at the King Hill station decreased from 

the 1958 water year, the tons per acre-foot of dissolved-solids 

remained essentially the same.

Boise River basin . A marked decrease in discharge over the 

previous year caused a 200 percent increase in dissolved-solids

CRITERIA OF WATER QUALITY

Many different classifications of water for irrigation appear in 

the literature; however, most of the development in this field has 

been made in the last 30 years. Scofield and Headley (1921) were 

among the first important contributors to water-quality criteria; 

they pointed out the hazards from the use of high-sodium water. 

A brief historical resume of these early developments is given in 

Water-Supply Paper 1264, the first of this'series of reports.

Although the above classifications have relied principally on 

specific conductance as the criterion for total salt concentrations,
20 QUALITY FOR IRRIGATION, 1959

investigators generally place emphasis on the composition of th^ 

water, as indicated by the analysis of dissolved constituents in 

equivalents per million. For example, Eaton (1950) discusser 

precipitation of calcium and magnesium carbonate and its effects 

on the sodium percentage in the soil solution. Baton's suggestion 

of "residual sodium carbonate" in irrigation waters as related to 

the base exchange of the soil has assumed added importance in 

soil permeability studies.

Thorne and Thorne (1951) in developing a system for classifying 

Utah waters for irrigation used a diagram similar to that cf 

Wilcox (1948) and designated categories by a series of numbers 

and letters: 1A....... 5E. The numbers 1 to 5 denote increasing

concentrations of dissolved solids, and the letters A to E increasing sodium percentages in the water with increasing probabilities 

for developing alkali soil conditions. Class 1A water, in which 

specific conductance ranges from 0 to 750 micromhos and the percent sodium from 0 to an approximate maximum of 70, can b? 

used safely on most soils. Class 5E waters, those having specific 

conductance greater than 5,000 micromhos and percent sodium of 

about 90 and above, are generally unsatisfactory for irrigation.

The United States Salinity Laboratory Staff (1954) recently released a classification that incorporates many of the desirable 

features of the early classifications together with more recent 

developments. Empirical equations are used in developing a diagram for the classification of irrigation waters. Although th^ 

classification embodies both research and field observations, it 

is tentative and should be used for general guidance only.

A. Salinity hazard

Waters are divided into four classes: low salinity, medium 

salinity, high salinity, and very high salinity, the dividing point? 

between classes being 250, 750, and 2,250 micromhos per centimeter. They range from water that can be used for irrigation of 

most crops on most soils to that which is not suitable for irrigation under ordinary conditions.

B. Sodium hazard

The Salinity Laboratory introduced the term "Sodiumadsorption-ratio (SAR)," a ratio for irrigation waters and soil extracts used to express the relative activity of sodium ions in exchange reactions with the soil. This ratio is expressed by tto
CRITERIA OF WATER QUALITY 21

equation:

SAR= Na+

rvhere the concentrations of the ions are expressed in milliequivalents per liter (or equivalents per million for most irrigation 

 waters). It has more significance than percent sodium for use as 

an index of the sodium or alkali hazard of the water because it reates more directly to the adsorption of sodium by the soil.

Waters are divided into four classes with respect to sodium or 

alkali hazard: low, medium, high, and very high, depending upon 

" .he SAR value and the specific conductance. At a conductance of 

'00 micromhos per centimeter the dividing points are at SAR 

values of 10, 18, and 26, but at 5,000 micromhos the correspond- 

; ng dividing points are at SAR values of approximately 2.5, 6. 5, 

and 11. Waters range in respect to sodium hazard from those 

vhichcan be used for irrigation on almost all soils to those which 

are generally unsatisfactory for irrigation.

C. Boron hazard

In assessing water quality on the basis of boron only, the 

classification uses the limits proposed by Scofield (1936). This 

grouping involves the ranges for sensitive, semitolerant, and tolerant crops, with respect to boron, for each of five classes.

D. Bicarbonate ion hazard

The effect of bicarbonate ion concentration on water quality is expressed in terms of "residual sodium carbonate" (RSC) 

which is defined by the equation:

RSC = (HC03 - + C03 ~) - (Ca++ + Mg++)

Then in appraising quality of irrigation water with the above 

classifications, the Salinity Laboratory Staff recommends that 

first consideration be given to salinity and alkali hazards, then to 

independent characteristics, boron or toxic elements, any OL.e of 

which may change the quality rating. Factors such as drainage 

and management practices, largely deter mine the effectiveness of 

irrigation activity.
