QUALITY OF SURFACE WATERS 

OF THE UNITED STATES, 1953

PARTS 9-14

INTRODUCTION

The quality-of-water investigations of the United States Geological Survey are concerned with chemical and physical characteristics of the surface and ground water supplies of the Nation. 

Most of the investigations carried on in cooperation with States 

and other Federal agencies deal with the amounts of matter in solution and in suspension in streams.

The records of chemical analysis, suspended sediment, and 

temperature for surface waters given in this volume serve as a 

basis for determining the suitability of the waters examined for 

industrial, agricultural, and domestic uses insofar as such use 

is affected by the dissolved or suspended mineral matter in the 

waters. The discharge of a stream and, to a lesser extent, the 

chemical quality are related to variations in rainfall and other 

forms of precipitation. In general, lower concentrations of dissolved solids may be expected during the periods of high flow than 

during periods of low flow. The concentration in some streams 

may change materially with relatively small variations in flow, 

whereas for other streams the quality may remain relatively uniform throughout large ranges in discharge. The quantities of suspended sediment carried by streams are also related to discharge, 

and during flood periods the sediment concentrations in many 

streams vary over wide ranges.

The regular yearly publication of records of chemical analyses, suspended sediment, and water temperature was begun by 

the Geological Survey in 1941. The annual records prior to 1948 

were published in a single volume for the entire country. Beginning in 1948, the records were published in two volumes, and beginning in 1950, in four volumes, covering the drainage basins 

shown in figure 1. The samples for which data are given were 

collected from October 1, 1952 , to September 30, 1953 . Descriptive statements are given for each sampling station for which 

regular series of chemical analyses or sediment determinations 

have been made. These statements include the location of the 

stream-sampling station, drainage area, length of time for which 

records are available, extremes of dissolved solids, hardness, 

sediment loads, water temperature, and other pertinent data.

Figure 1. Map of the United States showing basins covered 

by the four water-supply papers on quality of surface waters 

in 1953. The shaded portion represents the section of the 

country covered by this volume; the unshaded portion represents the section of the country covered by other watersupply papers.

Records of water discharge of the streams at, or near, the sampling point for the sampling period are included in most tables.of 

analyses. The records are arranged by drainage basins, according to Geological Survey practice in reporting records of stream 

flow.

Beginning with the series of reports for the water year ending 

September 30, 1951, the order of listing station records has been 

changed. In this report, stations on tributary streams are listed 

between stations on the main stream in the order in which those 

tributaries enter the main stem. Stations on tributaries to tributaries are inserted in a similar manner.

During the year ended September 30, 1953, 55 regular sampling stations on 42 streams for the study of the chemical character of surface waters were maintained by the Geological Survey 

in the area covered by this volume. Samples were collected less 

frequently during the year at many other points. Water temperatures were measured daily at 108 of the regular sampling stations. 

Not all analyses of samples of surface water collected during the 

year have been included. Single analyses of an incomplete nature 

generally have been omitted. Also, determinations made on the
COLLECTION AND EXAMINATION OF SAMPLES 3

daily samples before compositing have not been reported. Specific conductance was usually determined on each daily sample, 

and pH, chloride, or other determinations were also made on many 

of the daily samples. As noted in the table headings these data 

are available for reference at the district offices listed under Division of Work, on pages 19-20.

Quantities of suspended sediment are reported for 20 stations during the year ended September 30, 1953 . The sediment 

samples were collected one or more times daily at most stations, 

depending on the rate of flow and changes in stage of the stream. 

Sediment samples were collected less frequently during the year 

at many other points. In connection with measurements of sediment discharge, sizes of sediment particles were determined at 

19 of the stations. As noted under "Remarks" in the table headings, suspended-sediment concentrations also were determined 

from the samples collected for chemical analyses in some parts 

of the country. The data do not provide a reliable basis for computing the loads of suspended sediment carried by the stream but 

may be of value for design and operation of filtration plants utilizing these stream waters. Records of these infrequent determinations are available for reference in the district offices listed.

Material which is transported essentially in continuous contact 

with the stream bed is termed bed load and is not considered in 

this report. All other undissolved material in transport is termed 

suspended sediment and generally constitutes the major part of the 

total sediment load. At the present time no reliable method has 

been developed for determining bed load on a routine basis.

COLLECTION AND EXAMINATION OF SAMPLES 

CHEMICAL QUALITY

Samples for chemical analyses were usually collected daily at, 

or near, points on streams where gaging stations are maintained 

for measurement of water discharge. Most of the analyses were 

made on 10-day composites of daily samples collected for a period 

of a year at each sampling point. Three composite samples were 

usually prepared each month by mixing together equal volumes of 

daily samples collected from the 1st to the 10th, from the llth to 

the 20th, and during the remainder of the month. For some streams 

that are subject to sudden and large changes in chemical composition or concentration, samples were composited for shorter periods 

on the basis of the concentration of dissolved solids indicated by 

measurements of specific conductance of the daily samples.

The samples were analyzed according to methods regularly 

used by the Geological Survey. These methods are essentially the 

same as or are modifications of methods described in recognized
4 QUALITY OF SURFACE WATERS, 1953

authoritative publications for the mineral analysis of water samples (Collins, 1928; Am. Public Health Assoc., 1946).

For those waters containing moderately large quantities of 

soluble salts, the value reported for dissolved solids is the sum 

of the quantities of the various determined constituents using the 

carbonate equivalent of the reported bicarbonate. In other analyses the value reported as dissolved solids is the residue on evaporation after drying at 180°C for 1 hour. Specific conductance is 

given for most analyses and was determined by means of a conductance bridge using a standard potassium chloride solution as 

reference.

SUSPENDED SEDIMENT

In general, samples were collected daily with the US D-43 

depth-integrating sampler (U. S. Inter-agency, 1948, p. 70-76) 

from a fixed sampling point at one vertical in the cross section. 

The US DH-48 hand sampler was used at many stations during 

periods of low flow. Suspended-sediment samples, consisting of 

depth-integrated samples at three or more verticals in the cross 

section were made periodically to determine the cross-sectional 

distribution of the suspended concentration with respect to that at 

the daily sampling vertical. In streams where comparatively 

rapid fluctuations in transverse distribution of water discharge or 

sediment concentration are encountered at the sampling point, 

samples were taken regularly at two or more verticals to determine the average concentration across the section. During periods of high flow, samples were taken two or more times throughout the day at many sampling stations, and during periods of rapidly changing flow samples were taken hourly at some stations.

Sediment concentrations were determined by filtration or evaporation of the samples as required. At many stations the mean 

daily concentration for some days was obtained by plotting the instantaneous concentrations on the original or copies of the original 

gage-height chart. The plotted concentrations adjusted, if necessary, for cross-sectional distribution with respect to that at the 

daily sampling vertical, were connected or averaged by continuous 

curves to obtain a concentration graph. This graph represented 

the estimated concentration at any time and, for most periods, 

mean daily concentrations were deter mined from the graph. When 

the concentration and water discharge were changing rapidly, the 

day was often subdivided for this computation. For some periods 

when the day-to-day variation in the concentration was negligible, 

the data were not plotted, and the average concentration of the 

samples was used as the mean concentration for the day. For 

certain stations, when the discharge and sediment concentrations 

were relatively low and varied only slightly from day to day, the
COLLECTION AND EXAMINATION OF SAMPLES 5

samples for a number of days were composited and the mean daily 

concentrations and mean daily loads are shown.

For some periods when no samples were collected, daily sediment loads were estimated on the basis of water discharge, sediment concentrations observed immediately preceding and following the periods, and sediment loads for other periods of similar 

discharge. The estimates were further guided by weather conditions and sediment discharge for other stations.

In many instances where there were no observations for several days, the sediment loads for individual days are not estimated, as numerous factors influencing the quantities of transported sediment made it very difficult to make accurate estimates 

of sediment loads for individual days. However, estimated sediment loads for missing days in an otherwise continuous period of 

sampling have been included in monthly and annual totals for most 

streams to provide a complete record.

In addition to the records of total quantities of sediment, rec - 

ords of the particle sizes of sediment are included also. The particle sizes of the suspended sediments were determined periodically for many of the stations. As much of the material carried 

in suspension can pass through the finest sieves, the bottomwithdrawal tube method (U. S. Inter-agency, 1943, p. 82-90) was 

used in most of the analyses. Generally, sieves were used in the 

determination of particle sizes for sediments which were predominantly coarser than 0.062 mm. Size distribution for some sediments was determined by a combination of sieves and pipette methods in which the size fraction 0.062 mm and larger was analyzed 

by sieves and that smaller than 0.062 mm was analyzed by the 

pipette method (Kilmer and Alexander, 1949). Native or distilled 

water, as noted in the tables of analyses, was used as the settling 

medium. In some instances, chemical dispersing agents were 

added to the settling medium. As settling diameters of the clay 

and colloidal fractions are often affected by the chemical charadter of the settling medium, analyses made using native water may 

more nearly simulate particle sizes existing in the stream. Results of analyses using distilled water or using a settling medium 

containing dispersing agents approximate ultimate particle sizes 

of the finer fractions. The concentration of sediment suspension 

for analysis was reduced to less than 5,000 parts per million, 

where necessary, by means of a sample splitter, in order to stay 

within limits recommended for the bottom-withdrawal tube or pipette method. The concentration of suspended sediment used in the 

bottom-withdrawal tube or pipette cylinder was often different from 

the concentration in the original suspension. The concentration at 

which analyses were made is indicated in the appropriate tables.

QUALITY OF SURFACE WATERS, 1953

TEMPERATURE

For most of the stations, daily water temperatures were obtained at the time that the chemical quality or sediment samples 

were collected. So far as practicable the water temperatures were 

observed at about the same time each day for an individual river 

station in order that the data would be relatively unaffected by diurnal variations in temperature. For most large, swiftly flowing 

streams the diurnal variation in water temperature is probably 

small, but for sluggish or shallow streams the daily range in temperature may amount to several degrees and may follow closely 

changes in air temperature. The thermometers used for determination of water temperature were accurate to plus or minus 

about 0.5°F.

Records of thermograph observations consist of maximum and 

minimum temperatures for each day, and the monthly averages of 

the maximum daily and minimum daily temperatures.

EXPRESSION OF RESULTS

The dissolved mineral constituents are reported in parts per 

million. A part per million is a unit weight of a constituent in a 

million unit weights of water. Equivalents per million are not 

given in this report although the expression of analyses in equivalents per million is sometimes preferred. An equivalent per million is a unit chemical combining weight of a constituent in a million unit weights of water and is calculated by dividing the concentration in parts per million by the chemical combining weight of 

the constituent. For convenience in making this con version the reciprocals of chemical combining weights of the most commonly 

reported constituents (ions) are given in the following table:

Constituent Factor Constituent Factor

Results given in parts per million can be converted to grains

EXPRESSION OF RESULTS 7

tity of sodium and potassium is given in some analyses and is the 

quantity of sodium needed in addition to the calcium and magnesium 

to balance the acid constituents.

The hardness, as calcium carbonate (CaCO3 ), is calculated from 

the equivalents of calcium and magnesium exceptfor afew samples 

for which the reported values also include equivalents of free mineral acid, aluminum, iron, and manganese when present in significant quantities. The hardness caused by calcium and magnesium 

(and other ions if significant) equivalentto the carbonate and bicarbonate is called carbonate hardness; the hardness in excess of this 

quantity is called noncarbonate hardness.

In the analyses of most waters used for irrigation, the quantity of dissolved solids is given in tons per acre-foot as well as in 

parts per million. Percent sodium is computed for those analyses 

where sodium and potassium are reported separately by dividing 

the equivalents per million of sodium by the sum of the equivalents 

per million of calcium, magnesium, sodium, and potassium and 

multiplying the quotient by 100. In analyses where sodium and potassium were calculated and reported as a combined value, the 

value reported for percent sodium will include the equivalent quantity of potassium. In most waters of moderate to high concentration, the proportion of potassium is much smaller than that of sodium.

Specific conductance values are expressed in reciprocal ohms 

times 10^ (micromhos at 25°C). The discharge of the streams is 

reported in cubic feet-per second (see Streamf low, p. 20) and the 

temperature in degrees Fahrenheit. Color is expressed in units of 

the platinum-cobalt scale proposed by Hazen (1892, p. 427-428). 

Hydrogen-ion concentration is expressed in terms of pH units. By 

definition the pH value of a solution is the negative logarithm of the 

concentration of gram ions of hydrogen. However, the pH meter 

which is generally used in Survey laboratories, determines the activity of the hydrogen ions as distinguished from concentration.

An average of analyses (arithmetical or weighted) for the water 

year is givenfor most daily sampling stations. An arithmetical average represents the composition of water that would be contained 

in a vessel or reservoir that had received equal quantities of water 

from the river each day for the water year. A weighted average 

represents approximately the composition of water that would be 

found in a reservoir containing all of the water passing a given station during the year after thorough mixing in the reservoir. The 

weighted average of the analyses is computed by multiplying the 

discharge for the sampling period by the quantities of the individual 

constituents for the corresponding period and dividing the sum of 

the products by the sum of the discharges. Water as represented 

by the weighted average is less concentrated than that represented 

by the average of the individual analyses for most streams because 

at times of high discharge the rivers generally have lower concentrations of dissolved solids.

Mean daily sediment concentrations are expressed in parts per 

million by weight. A part per million of sediment is computed as
8 QUALITY OF SURFACE WATERS, 1953

1,000, 000 times the ratio of the weight of sediment to the weight 

of water-sediment mixture. Daily sediment loads are expressed 

in tons per day, and except for subdivided days are usually obtained 

by multiplying daily mean sediment concentration in parts per million by the daily mean discharge, and the appropriate conversion 

factor, normally 0.0027.

Particle-size analyses are expressed in percentages finer than 

indicated sizes in millimeters. The size classification used in 

this report is that recommended by the American Geophysical Union Subcommittee on sediment terminology (Lane, et al; 1947, p. 

937). Other data included as pertinent to the size analyses for 

many streams are the date of collection, the stream discharge 

and sediment concentration when sample was collected, the concentration of the suspension during analysis, and the method of 

analysis.

COMPOSITION OF SURFACE WATERS

All natural waters contain dissolved mineral matter. Water 

in contact with soils or rock, even for only a few hours, will dissolve some rock materials. The quantity of dissolved mineral 

matter in a natural water depends primarily on the type of rocks 

or soils through which the water has passed and the length of time 

it has been in contact with the rocks or soils. Some streams are 

fed by both surface runoff and underground water from springs or 

seeps. Such streams reflect the chemical character of their concentrated underground sources during dry periods and are more 

dilute during periods of heavy rainfall. Underground water is usually more highly concentrated than surface runoff as it remains 

in contact with the rocks and soils for much longer periods. The 

concentration of dissolved solids in a river water is frequently increased by drainage from mines or oil fields, by the addition of 

industrial or municipal wastes, or--in irrigated regions by return drain waters.

The mineral constituents and physical properties of natural 

waters reported in the tables of analyses include those that have 

a practical bearing on the value of the waters for most purposes. 

The analyses generally include results for silica, iron, calcium, 

magnesium, sodium, potassium (or sodium and potassium together 

as sodium),bicarbonate, sulfate, chloride, fluoride, nitrate, boron, and dissolved solids. Aluminum, manganese, color, pH, 

acidity, oxygen consumed, and other dissolved constituents and 

physical properties are reported for certain streams. The source 

and significance of the different constituents and properties of natural waters are discussed in the following paragraphs.
COMPOSITION OF SURFACE WATERS

MINERAL CONSTITUENTS IN SOLUTION

Silica (SiO2 )

Silica is dissolved from practically all rocks. Some natural 

surface waters contain less than 5 parts per million of silica and 

few contain more than 50 parts, but the more common range is 

from 10 to 30 parts per million. Silica affects the usefulness of 

a water because it contributes to the formation of boiler scale; it 

usually is removed from feed water for high-pressure boilers. 

Silica also forms troublesome deposits on the blades of steam turbines.

Aluminum (Al)

Aluminum is usually present only in negligible quantities in 

natural waters except in areas where the waters have been in contact with the more soluble rocks of high aluminum contentsuch as 

bauxite and certain shales. Acid waters often contain large amounts of aluminum. It may be troublesome in feed waters where 

it tends to be deposited as a scale on boiler tubes.

Manganese (Mn)

Manganese is dissolved in appreciable quantities from rocks 

in some sections of the country. Waters impounded in large reservoirs may contain manganese that has been dissolved from the 

mud on the bottom of the reservoir by action of carbon dioxide 

produced by anaerobic fermentation of organic matter. Manganese is not regularly determined in areas where it is not present 

in the waters in appreciable amounts. It is especially objectionable in water used in laundry work and in textile processing. Concentrations as low as 0.2 part per million may cause a dark-brown 

or black stain on fabrics and porcelain fixtures. Appreciable quantities of manganese are often found in waters containing objectionable quantities of iron.

Iron (Fe)

Iron is dissolved from many rocks and soils. On exposure to 

the air, normal basic waters that contain more than 1 part per
10 QUALITY OF SURFACE WATERS, 1953

million of iron soon become turbid with the insoluble reddish ferric oxide produced by oxidation. Surface waters, therefore, seldom contain as much as 1 part per million of dissolved iron, although some acid waters carry large quantities of iron in solution. 

Iron causes reddish-brown stains on white porcelain or enameled 

ware and fixtures and on fabrics washed in the water.

Calcium (Ca)

Calcium is dissolved from practically all rocks and soils, but 

the highest concentrations are usually found in waters that have 

been in contact with limestone, dolomite, and gypsum. Calcium 

and magnesium make water hard and are largely responsible for 

the formation of boiler scale. Most waters associated with granite 

or silicious sands contain less than 10 parts per million of calcium; waters in areas where rocks are composed of dolomite and 

limestone contain from 30 to 100 parts per million; and waters 

that have come in contact with deposits of gypsum may contain 

several hundred parts per million.

Magnesium (Mg)

Magnesium is dissolved from many rocks, particularly from 

dolomitic rocks. Its effect in water is similar to that of calcium. 

The magnesium in soft waters may amount to only 1 or 2 parts 

per million, but water in areas that contain large quantities of 

dolomite or other magnesium-bearing rocks may contain from 20 

to 100 parts per million or more of magnesium.

Sodium and potassium (Na and K)

Sodium and potassium are dissolved from practically all rocks. 

Sodium is the predominant cation in some of the more highly mineralized waters found in the western United States. Natural waters that contain only 3 or 4 parts per million of the two together 

are likely to carry almost as much potassium as sodium. As the 

total quantity of these constituents increases, the proportion of 

sodium becomes much greater. Moderate quantities of sodium 

and potassium have little effect on the usefulness of the water for 

most purposes, but waters that carry more than 50 or 100 parts 

per million of the two may require careful operation of steam 

boilers to prevent foaming. More highly mineralized waters that 

contain a large proportion of sodium salts may be unsatisfactory 

for irrigation.
COMPOSITION OF SURFACE WATERS 11

Carbonate and bicarbonate (CO 3 and HCO3 )

Bicarbonate occurs in waters largely through the action of 

carbon dioxide, which enables the water to dissolve carbonates 

of calcium and magnesium. Carbonate as such is not usually 

present in appreciable quantities in natural waters. The bicarbonate in waters that come from relatively insoluble rocks may 

amount to less than 50 parts per million; many waters from limestone contain from 200 to 400 parts per million. Bicarbonate in 

moderate concentrations in water has no effect on its value for 

most uses. Bicarbonate or carbonate is an aid in coagulation for 

the removal of suspended matter from water.

Sulfate (SO4)

Sulfate is dissolved from many rocks and soils--in especially 

large quantities from gypsum and from beds of shale. It is formed also by the oxidation of sulfides of iron and is therefore present in considerable quantities in waters from mines. Sulfate in 

waters that contain much calcium and magnesium causes the formation of hard scale in steam boilers and may increase the cost 

of softening the water.

Chloride (Cl)

Chloride is dissolved from rock materials in all parts of the 

country. Surface waters in the humid regions are usually low in 

chloride, whereas streams in arid or semiarid regions may contain several hundred parts per million of chloride leached from 

soils and rocks, especially where the streams receive return 

drainage from irrigated lands or are affected by ground-water-inflow carrying appreciable quantities of chloride. Large quantities 

of chloride may affect the industrial use of water by increasing 

the corrosiveness of waters that contain large quantities of calcium and magnesium.

Fluoride (F)

Fluoride has been reported as being present in some rocks to 

about the same extent as chloride. However, the quantity of fluoridein natural surface waters is ordinarily very small compared 

to that of chloride. Recent investigations indicate that the incidence of dental caries is less when there are small amounts of
12 QUALITY OF SURFACE WATERS, 1953

fluoride present in the water supply than when there is none. However, excess fluoride in water is associated with the dental defect 

known as mottled enamel if the water is used for drinking by young 

children during calcification or formation of the teeth (Dean, 1936, 

p. 1269-1272). This defect becomes increasingly noticeable as the 

quantity of fluoride in water increases above 1.5 to 2. 0 parts per 

million.

Nitrate (NO3)

Nitrate in water is considered a final oxidation product of nitrogenous material and in some instances may indicate previous 

contamination by sewage or other organic matter. The quantities 

of nitrate present in surface waters usually amount to less than 5 

parts per million (as NO3) and have no effect on the value of the 

water for ordinary uses.

It has been reported that as much as 2 parts per million of nitrate in boiler water tends to decrease intercrystalline cracking 

of boiler steel. Studies made in Illinois indicate that nitrates in 

excess of 70 parts per million (as NO3) may contribute to methemoglobinemia ("blue babies") (Faucett and Miller, 1946, p. 593), 

and more recent investigations conducted in Ohio show that drinking water containing nitrates in the range of 44 to 88 parts per million or more (as NO3) may be the cause of methemoglobinemia in 

infants (Waring, 1949). In a report published by the National Research Council, Maxcy (1950, p. 271) concludes that a nitrate content in excess of 44 parts per million (as NOg) should be regarded 

as unsafe for infant feeding.

Boron (B)

Boron in small quantities has been found essential for plant 

growth, but irrigation water containing more than 1 part per million boron is detrimental to citrus and other boron-sensitive crops. 

Boron is reported in Survey analyses of surface waters in arid and 

semiarid regions of the Southwest and West where irrigation is 

practiced or contemplated, but few of the surface waters analyzed 

have harmful concentrations of boron.

Dissolved solids

The reported quantity of dissolved solids--the residue on evaporation--consists mainly of the dissolved mineral constituents in 

the water. It may also contain some organic matter and water of 

crystallization. Waters with less than 500 parts per million of dis-
COMPOSITION OF SURFACE WATERS 13

solved solids are usually satisfactory for domestic and some industrial uses. Waters containing several thousand parts per million of dissolved solids are sometimes successfully used for irrigation where practices permit the removal of soluble salts through 

the application of large volumes of water on well-drained lands.

PROPERTIES AND CHARACTERISTICS OF WATER 

Oxygen consumed

The value for oxygen consumed furnishes an approximation of 

the oxidizable matter in the unfiltered and filtered samples and 

gives a partial measure of polluting materials such as sewage and 

oxidizable industrial wastes. Naturally highly colored waters may 

have relatively high oxygen consumed, although waters that are 

not noticeably colored may contain oxidizable material.

Color

In water analysis the term "color" refers to the appearance 

of water that is free from suspended solids. Many turbid waters 

that appear yellow, red, or brown when viewed in the stream show 

very little color after the suspended matter has been removed. 

The yellow-to-brown color of some waters is usually caused by 

organic matter extracted from leaves, roots, and other organic 

substances in the ground. In some areas objectionable color in 

water results from industrial wastes and sewage. Clear deep water may appear blue as the result of a scattering of sunlight by the 

water molecules. Water for domestic use and some industrial uses 

should be free from any perceptible color. A color less than 10 

units usually passes unnoticed. Some swamp waters have natural 

color of 200 to 300 units or more.

Hydrogen-ion concentration (pH)

The degree of acidity or alkalinity of water, as indicated by 

the hydrogen-ion concentration, expressed as pH, is related to 

the corrosive properties of water, and is useful in determining 

the proper treatment for coagulation that may be necessary at water-treatment plants. A pH value of 7.0 indicates that the water 

is neither acid nor alkaline. Waters having pH values progressively lower than 7.0 denote increasing acidity, whereas values 

progressively higher than 7.0 denote increasing alkalinity (see p. 

7 ). The pH of most natural surface waters ranges between 6
14 QUALITY OF SURFACE WATERS, 1953

and 8. Some alkaline surface waters have pH values greater than 

8.0, and waters containing free mineral acid usually have pH values 

less than 4. 5.

Specific conductance (micromhos at 25°C)

The specific conductance of a water is a measure of its capacity to conduct a current of electricity. The conductance varies 

with the concentration and degree of ionization of the different minerals in solution and with the temperature of the water. When considered in conjunction with results of determinations for other constituents, specific conductance is a useful determination and plays 

an important part in indicating changes in concentration of the total quantity of dissolved minerals in surface waters. (See p. 7.)

Hardness

Hardness is the characteristic of water that receives the most 

attention in industrial and domestic use. It is usually recognized 

by the increased quantity of soap required to produce lather. The 

use of hard water is also objectionable because it contributes to 

the formation of scale in boilers, water heaters, radiators, and 

pipes, with the resultant decrease in rate of heat transfer, possibility of boiler failure, and loss of flow.

Hardness is caused almost entirely by compounds of calcium 

and magnesium. Other constituents--such as iron, manganese, 

aluminum, barium, strontium, and free acid--also cause hardness, although they usually are not present in quantities large 

enough to have any appreciable effect. Water that has less than 

60 parts per million of hardness is usually rated as soft and suitable for many purposes without further softening. Waters with 

hardness ranging from 61 to 120 parts per million may be considered moderately hard, but this degree of hardness does not 

seriously interfere with the use of water for many purposes except for use in high-pressure steam boilers and in some industrial processes. Waters with hardness ranging from 121 to 200 

parts per million are considered hard, and laundries and industries may profitably soften such supplies. Water with hardness 

above 200 parts per million usually requires some softening before 

being used for most purposes.

Total acidity

The total acidity of a natural water represents the content of 

free carbon dioxide, mineral acids, and salts --especially sulfates
COMPOSITION OF SURFACE WATERS 15

of iron and aluminum-- that hydrolyze to give hydrogen ions. Acid 

waters are very corrosive and generally contain excessive amounts 

of objectionable constituents, such as iron, aluminum, and manganese.

Corrosiveness

The corrosiveness of a water is that property which makes the 

water aggressive to metal surfaces and frequently results in the 

appearance of the "red water" caused by solution of iron. The disadvantages of iron in water have been discussed previously. Additionally, corrosion causes the deterioration of water pipes, steam 

boilers, and water-heating equipment. Many waters that do not 

appreciably cor rode cold-water lines will aggressively attack hotwater lines. Oxygen, carbon dioxide, free acid, and acid-generating salts are the principal constituents in water that cause corrosion. In a general way, very soft waters of low mineral content 

tend to be more corrosive than hard waters containing appreciable 

quantities of carbonates and bicarbonates of calcium and magnesium.

Percent sodium

Percent sodium is reported in most of the analyses of waters 

collected from streams in the western part of the country where 

irrigation is practiced extensively. The proportion of sodium to 

all the basic constituents in the water has a bearing on the suitability of a water for irrigation. (See p. 7. ) Waters in which the 

percent sodium is more than 60 may be injurious when applied to 

certain types of soils, particularly when adequate drainage is not 

provided(Magistad and Christiansen, 1944, p. 8-9; Wilcox, 1948, 

P. 6).

Sodium-adsorption-ratio

Sodium-adsorption-ratio (SAR) is the relative proportion of 

sodium to other cations in an irrigation water.

SAR= Na+

\y (Ca+++Mg++)/2

where the ionic concentrations are expressed in milliequivalents

per liter (or equivalents per million for most irrigation waters).

The term is used for soil extracts and irrigation waters to ex-
16 QUALITY OF SURFACE WATERS, 1953

press the relative activity of sodium ions in exchange reactions 

with soil. SAR provides an estimate of the sodium or alkali hazard and reportedly is more significant for interpreting water quality than percent sodium because it relates more directly to the exchangeable sodium percentage the soil will attain when it and the 

water are in equilibrium.

The U. S. Salinity Laboratory diagram for classifying waters 

for irrigation divides water into four classes with respect to sodium hazard, the dividing points being at SAR values of 10, 18, and 

26. They range from low-sodium water that can be used for irrigation on almost all soils to very high-sodium water which is generally unsatisfactory for irrigation.

SEDIMENT

Fluvial sediment is generally regarded as that sediment which 

is transported by, suspended in, or deposited by water. Suspended sediment is that sediment which remains in suspension in water owing to the upward components of turbulent currents or by 

colloidal suspension. Most fluvial sediment results from the normal process of erosion, which in turn is part of the geologic cycle 

of rock transformation. In some instances, this normal process 

may have been accelerated by agricultural practices. Sediment 

also results from a number of industrial activities. In certain 

sections, waste materials from mining, logging, oil-field, and 

other industrial operations introduce large quantities of suspended 

as well as dissolved material.

The quantity of sediment, transported or available for transportation, is affected by climatic conditions, form or nature of 

precipitation, vegetal cover, topography, and land use. An important property of fluvial sediment is the fall velocity of the particles in transport. Particle sizes, as determined by various 

methods, represent mechanical diameters, which are related to 

sedimentation diameters indirectly. Sediment particles in the 

sand-size (larger than 0. 062 mm) range do not appear to be affected by flocculation or dispersion resulting from the mineral 

constituents in solution. The sedimentation diameter of clay and 

silt particles in suspension may vary considerably from point to 

point in a stream or reservoir, depending on the mineral matter 

in solution and in suspension and the degree of turbulence present. 

The size of sediment particles in transport at any point depends 

on the type of credible and soluble material in the drainage area, 

the degree of flocculation present, time in transport, and characteristics of the transporting flow. The flow characteristics include velocity of water, turbulence, and the depth, width, and 

roughness of the channel. As a result of these variable charac-
PUBLICATIONS 17

teristics, the size of particles transported, as well as the total 

sediment load, is in constant adjustment with the characteristics 

and physical features of the stream and drainage area.

PUBLICATIONS

Reports giving chemical analyses, suspended-sediment loads, 

and water temperatures of samples of surface water made by the 

Geological Survey have been published yearly since 1941. Records 

for the years ended September 30, 1941, 1942, 1943, 1944, 1945, 

1946, 1947, 1948, 1949, 1950, 1951, and 1952, for many of the 

stations listed in this report are given in Water-Supply Papers 942, 

950, 970, 1022, 1030, 1050, 1102, 1133, 1163, 1189, 1200, and 

1253.

COOPERATION

Financial assistance was furnished by the Bureau of Reclamation of the United States Department of the Interior, in the operation of some stations in Arizona. Investigations of chemical quality in the Great Basin and Pacific Slope basins in California were 

carried on in cooperation with the State of California. Financial 

assistance was also furnished by the Corps of Engineers, United 

States Army, in operation of a sediment and chemical quality station on the East Fork Russian River near Ukiah, Calif. Investigations of chemical quality in the upper Virgin River basin, Utah, 

were initiated in 1951 in cooperation with the State of Utah.
DIVISION OF WORK 19

Sedimentation studies in the Pacific Slope basins in Washington 

were begun in 1950 with the City of Tacoma.

Assistance in collecting records was given by many municipal, State, and Federal agencies.

In addition to the cooperative program, many of the stations 

were operated from funds appropriated directly to the Geological 

Survey for quality-of-water investigations. Investigation of the 

chemical quality and suspended-sediment loads in the Colorado 

River basin in Arizona, Colorado, Nevada, and Utah have been 

carried on as a continuing Federal project since 1925.

DIVISION OF WORK

The quality-of-water program was conducted by the Water 

Resources Division of the Geological Survey, C. G. Paulsen, Chief 

Hydraulic Engineer, and S. K. Love, Chief of the Quality of Water 

Branch. The records were collected and prepared for publication 

under supervision of district or regional chemists as follows: In 

Arizona and New Mexico J. D. Hem; in Colorado and Wyoming 

(Color ado River basin), Nevada, Utah, California, Washington, 

Oregon, and Idaho--C. S. Howard. Any additional information on

Most of the records of stream discharge, used in conjunction 

with the chemical analyses and in the computation of sediment loads 

in this volume, are published in Geological Survey reports on the 

surface-water supply of the United States. The discharge reported 

for a composite sample is usually the average of the mean daily 

discharges for the normal composite period. For analyses in which 

the composite periods differ fromthe normal 10 or 11-day period, 

the discharges reported are the averages of the mean daily discharges for the days indicated. The discharges reported in the 

tables of single analyses are either daily mean discharges or discharges for the time at which samples were collected, computed 

from a stage-discharge relation or from a discharge measurement.
