QUALITY OF SURFACE WATERS 

OF THE UNITED STATES, 1948

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 

water temperature for surface waters given in this volume serve 

as a basis for determining the suitability of the waters examined 

for industrial, agricultural, and for 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 heretofore have been 

published in a single volume for the entire country. Beginning 

this year, the records are being published in two volumes, covering the drainage basins shown in figure 1. The samples for which 

data are given were collected from October 1, 1947, to September 30, 1948. 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, 

total hardness, sediment loads, water temperature, and other pertinent data. 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.
QUALITY OF SURFACE WATERS, 1948

Figure 1. Map of the United States showing basins covered 

by the two Water-Supply Papers on quality of surface water 

in 1948. The shaded portion represents the section of the 

country covered by this volume.

During the year ended September 30, 1948, 105 daily sampling stations 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 43 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 daily samples before compositing have not been reported. Specific 

conductance was usually determined on each daily sample, andpH, 

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 page 17.

Quantities of suspended sediment are reported for 35 stations 

during the year ended September 30, 1948. The sediment samples 

were collected from one to five times daily at most stations, depending on the rate of flow and changes in stage. Sediment samples were collected less frequently during the year at many other 

points. In connection with measurements of sediment discharge, 

sizes of the sediment particles were determined at 17 of the stations. As noted under "Remarks" in the table headings, suspended-sediment concentrations were also determined from the samples collected for chemical analysis in some parts of the country. 

Records of these determinations are available for reference in the
COLLECTION AND EXAMINATION OF SAMPLES 3

district offices listed. 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.

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 analysis 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 quantities 

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, 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 authoritative publications for the mineral analysis of water 

samples (Collins, 1928; Am. Pub. 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 180C 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 depthintegrating sampler (U. S. Interagency, 1948, pp. 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. At intervals throughout the year, suspended-sediment
4 QUALITY OF SURFACE WATERS, 1948

samples, consisting of depth-integrated samples at three or more 

verticals in the cross section were made to determine the crosssectional 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 regularly taken at two or more verticals to 

determine the average concentration across the section. During 

periods of high flow samples we re 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 gageheight 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 determined 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 

samples for a number of days were composited and the me an daily 

concentrations and mean daily loads are shown.

For periods when no samples were taken, some daily sediment loads were estimated on the basis of water discharge, sediment concentrations or loads for adjacent days and similar periods, weather records, and comparison with records 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. Estimated sediment loads for 

missing periods 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, records of the particle sizes of sediment also are included. 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 bottom-withdrawal tube method (U. S. Inter-agency, 1943, pp. 82-90) was 

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

determination of sizes in excess of 0. 062 millimeter. Native or
EXPRESSION OF RESULTS 5

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 character of the settling medium, analyses made using native 

water 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 10, 000 parts per 

million, where necessary, by means of a sample splitter, in order to meet the limits recommended for the bottom-withdrawal 

tube method. The concentration of suspended sediment used in the 

bottom-withdrawal tube was often different from the concentration 

in the original suspension. The weight of sediment used is indicated in the tables of analyses.

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, butfor 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 had a limit of accuracy of plus or minus 1 F. Consequently water temperatures of 31 F have been included in this report.

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 though 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 conversion the 

reciprocals of chemical combining weights of the most commonly 

reported constituents are given in the following table:
6 QUALITY OF SURFACE WATERS, 1948

Constituent Factor Constituent Factor

Iron (Fe++) 0. 0358 Carbonate (CO3 ~~) 0. 0333

Iron (Fe+++) .0537 Bicarbonate (HCO3 ~) -- .0164

Magnesium (Mg++) .0822 Chloride (Cl") .0282

Sodium (Na+) .0435 Fluoride (F~) .0526

Potassium (K+) .0256 Nitrate (NO3 ') .0161

Results given in parts per million can be converted to grains 

per United States gallon by dividing by 17.12. A calculated quantity 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 radicles.

The total hardness, as calcium carbonate (CaCO3 ), is calculated from the equivalents of calcium and magnesium except for a 

few 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) equivalent to 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 has been 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 includes 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 

(micromhos at 25 C). The discharge of the streams is reported 

in second-feet (see Stream flow, p. 20) and the temperature in 

degrees Fahrenheit. Color is expressed in units of the platinumcobalt scale proposed by Hazen (1892, pp. 427-428). Hydrogenion concentration (pH) is given as the negative logarithm of the 

number of moles of ionized hydrogen per liter of water.

Average analyses (arithmetical or weighted) for the water year 

are given for most daily sampling stations. An arithmetical-average analysis 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-aver age analysis 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 analysis is com-
COMPOSITION OF SURFACE WATERS 7

puted 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. The weighted-average analysis shows less concentrated 

water 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 except for streams in the Colorado River 

and Rio Grande Basins which are expressed in percent by weight 

because of the frequency of concentrations in excess of 10 percent. One percent is equivalent to 10, 000 parts per million. Daily sediment loads are expressed in tons per day, usually obtained 

by multiplying mean daily sediment concentration in parts per million by the mean daily discharge and the conversion factor 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,
8 QUALITY OF SURFACE WATERS, 1948

boron, and dissolved solids. Aluminum, manganese, color, pH, 

acidity, and oxygen consumed are reported for certain streams. 

The source and significance of the different constituents and properties of natural waters are discussed in the following paragraphs.

MINERAL CONSTITUENTS IN SOLUTION

Silica (Si02)

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 scales; 

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 content such 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 darkbrown or black stain in fabrics and on 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 

million of iron soon become turbid with the insoluble reddish fer-
COMPOSITION OF SURFACE WATERS 9

ric 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.

Carbonate and bicarbonate (COs and HCOs)

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 wa224835 O - 52 - 2
10 QUALITY OF SURFACE WATERS, 1948

ters 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 (S04)

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. 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 fluoride in natural surface waters is ordinarily very small compared 

to that of chloride. 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. 

This condition becomes noticeable as the quantity of fluoride in 

water increases above 1 part per million. Recent investigations 

indicate that the incidence of dental caries is less when there are 

small amounts of fluoride present in the water supply than when 

there is none.

Nitrate (NOs)

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
COMPOSITION OF SURFACE WATERS 11

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 cuase 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 NO3 should be regarded as unsafe for infant feeding.

Boron (B)

Boron in small quantities has been found essential for p?ant 

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 analyses of surf ace 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 

dissolved 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 a rough indication 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
12 QUALITY OF SURFACE WATERS, 1948

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 waste sand 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 usually passes unnoticed. Some swamp waters have natural 

color of 200 to 300 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. Values progressively lower than 

7. 0 denote increasing acidity, whereas values progressively higher than 7. 0 denote increasing alkalinity. The pH of water indicates its activity towards metal surfaces. As the pH increases 

the corrosive activity of the water decreases. The pH of most 

natural surface waters ranges between 6 and 8. Some alkaline 

surface waters have pH values greater than 8. 0, and waters containing free mineral acid usually have values less than 4. 5.

Specific conductance (micromhos at 25 C)

Tlie 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 following changes in concentration of 

the total quantity of dissolved minerals in surface waters.

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. Hard 

water is also objectionable because of 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,
COMPOSITION OF SURFACE WATERS 13

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 are considered 

hard, and in the upper ranges laundries and industries may profitably soften the supply. 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 

of iron and aluminum that hydrolize 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. Besides the trouble caused by iron in water, corrosion causes the 

deterioration of water pipes, steam boilers, and water-heating equipment. Many waters that do not appreciably corrode cold-water 

lines will aggressively attack hot-water 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. 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, pp. 8-9; Wilcox, 1948, p. 6).
14 QUALITY OF SURFACE WATERS, 1948

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 (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 upon 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 upon 

the type of erodible 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 characteristics, 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.

20 QUALITY OF SURFACE WATERS, 1948

Investigations of the quality of water and of suspended-sediment loads in the Colorado River Basin in Arizona, Colorado, 

Nevada, New Mexico, and Utah have been carried on as a continuing Federal project since 1925. Studies of suspended-sediment 

loads in the middle Rio Grande in New Mexico were initiated as a 

Federal project in 1948. These investigations were under the direction of C. S. Howard, district chemist, Albuquerque, N. Mex.

Financial assistance was furnished by the Bureau of Reclamation for quality-of-water studies in the Rio Grande Basin in New 

Mexico, the Lower Rio Grande Basin in Texas, and at Lake Mead, 

Ariz. -Nev., and by the Corps of Engineers, U. S. Army, for the 

investigations in the vicinity of Conchas Dam, N. Mex., on Arkansas River near John Martin Dam, Colo., on the Mississippi 

River at St. Louis, and on the Trinity River in Texas.

STREAM FLOW

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 from the 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 either are daily 

mean discharges or are discharges for the time at which samples 

were collected, computed from a stage-discharge relation or 

from a discharge measurement.
