QUALITY OF SURFACE WATERS 

OF THE UNITED STATES, 1947

INTRODUCTION

This volume is the seventh in a series of reports giving chemical analyses, concentrations and loads of suspended sediment, 

and temperatures of the surface waters of the United States. The 

samples for which data are given were collected between October 1, 1946, and September 30, 1947. In addition, some suspended-sediment data for streams in the Missouri River Basin are included for the period November 1945 to October 1946. 

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.

During the year ended September 30, 1947, 101 daily sampling 

stations for the study of the chemical character of surface waters 

were maintained by the Geological Survey. Samples were collected 

less frequently during the year at many other points. Water temperatures were measured daily at 80 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, 

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 consultation at the district offices listed 

under Division of Work, on page 19.

Quantities of suspended sediment are reported for 50 stations 

during the year ended September 30, 1947, and for 22 stations in 

the Missouri River Basin for the period November 1945 to October 1946. The sediment samples were collected from one to five 

times daily at most stations, depending on the rate of flow. 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 31 

of the stations. As noted under "Remarks" in the table headings,

1
2 QUALITY OF SURFACE WATERS, 1947

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 consultation in the 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 includes the major part of the 

total sediment load. At the present time no reliable methods have 

been developed for determining bed load on a routine basis.

The records given on the following pages 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 periods of high flow than during periods of low 

flow. The concentration in some streams may change materially 

with relatively small variations inflow,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.

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 measments of specific conductance of the daily samples.

For streams in the Missouri River Basin the 10-day composite 

samples were prepared by taking from each daily sample a quantity proportionate to the mean-daily water discharge.

The samples were analyzed according to methods regularly
COLLECTION AND EXAMINATION OF SAMPLES 3

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 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. Eng. Office, 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. During periods of subfreezing temperatures, 

samples in the Missouri Basin were collected by observers with 

the modified Colorado River sampler. At intervals throughout 

the year, suspended-sediment samples, consisting of depth-integrated samples at three or more verticals in the cross section 

were made 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 

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 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 we re 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
4 QUALITY OF SURFACE WATERS, 1947

samples was used as the mean concentration for the day.

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. Thepa'rticle sizes of the suspended sediments were determined periodically for many of the stations. Since much of the material carried 

in suspension can pass through the finest sieves, the bottom-withdrawal tube method (U. S. Eng. Office, 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 disrtilled 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, but for sluggish or shallow streams the daily range 

in temperature may amount to> several degrees and may follow 

closely changes in air temperature.
EXPRESSION OF RESULTS

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 constituents. For convenience in making this conversion 

the reciprocals of chemical combining weights of the most commonly reported constituents are given in the following table:

Constituent Factor Constituent Factor

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

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

Calcium (Ca++) .0499 Sulfate (SO4 ~~) .0208

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 against the acid radicles.

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

some samples collected in Pennsylvania for which tfie 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 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 

(mhos x 10 5 at 25° C). For convenience the "mhos" are represented by "K" in the headings of the tables of analyses. The discharge of the streams is reported in second-feet (see Stream 

flow, p. 19) and the temperature in degrees Fahrenheit. Color 

is expressed in units of the platinum-cobalt scale proposed by 

Hazen (1892, pp. 427-428). Hydrogen-ion 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 arithmeticalaverage 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-average 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 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. 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.

Results of miscellaneous suspended-sediment discharge measurements are expressed in tons per day, obtained by multiplying 

instantaneous sediment concentration in parts per million, by the 

instantaneous discharge in second-feet, and the conversion factor 

0. 0027. Use of the same weight and time units in expressing both 

instantaneous rates and daily loads facilitates comparison.

Particle-size analyses are expressed in percentages finer than 

indicated sizes in millimeters. Other data included as pertinent 

to the size analyses for many streams are the date of collection, 

the stream discharge and sediment concentration, the concentration of the suspension during analysis, and the method of analysis.
COMPOSITION OF SURFACE WATERS

COMPOSITION OF SURFACE WATERS

All natural waters contain dissolved mineral matter. Water 

in contact with soils or rock, even for only a few hours, willdis - 

solve 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, 

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

oxygen consumed, and borate 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
8 QUALITY OF SURFACE WATERS, 1947

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 dark-brown 

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 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 withgranite 

or silicious sands contain less than 10 partsper 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 lor 2parts per
COMPOSITION OF SURFACE WATERS 9

million, but water in areas that contain large quantities of dolomite or other magnesium-bear ing 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 (C08 and HC08)

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 (SOJ

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
10 QUALITY OF SURFACE WATERS, 1947

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 (NO,)

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 met>- 

hemoglobinemia ("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 NO3) 

should be regarded as unsafe for infant feeding.

Borate (B03)

Boron has been found essential for plant growth, but in large 

quantities it is detrimental to citrus and other crops. Boron, as 

borate, is reported in analyses of surface waters in arid and 

semiarid regions of the Southwest and West where irrigation is 

practiced or contemplated, but few of the surf ace waters analyzed 

have harmful concentrations of boron.
COMPOSITION OF SURFACE WATERS 11

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 thousands 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 sample sand 

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 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-
12 QUALITY OF SURFACE WATERS, 1947

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 (KxlO 5 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 re suits 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, 

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.
COMPOSITION OF SURFACE WATERS 13

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 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. 

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 coldwater 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 mo re 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).

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
14 QUALITY OF SURFACE WATERS, 1947

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 

means, 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.

loads, and water temperatures of samples of surface water made

COOPERATION AND DIVISION OF WORK

The quality-of-water investigations in the States in the different drainage basins were madeunder cooperative agreementswith 

the organizations listed on pages 16-18. The work was conducted 

by the Water Resources Division of the Geological Survey, Carl 

G. Paulsen, chief hydraulic engineer, and S. K. Love, chief of 

the Quality of Water Branch. The records were collected and pre-. 

pared for publication under the supervision of the district chemists and engineers as follows: In Arkansas, G. A. Billingsley; in 

Florida, S. K. Love; in Georgia, North Carolina, South Carolina 

and Virginia, W. L. Lamar; in Iowa, L. C. Crawford and P. C. 

Benedict; in New Mexico, C. S. Howard; in Ohio and Pennsylvania, W. F. White; in Oklahoma, I. W. Walling; in Texas, W. 

W. Hastings. Any additional analytical data for the sampling stations can be obtained by writing the responsible Survey district 

office shown.

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. The work was under the direction of C. S. Howard, district chemist, Albuquerque, N. Mex.

The chemical quality and sediment investigations in the Missouri River Basin in Colorado, Iowa, Kansas, Montana, Nebraska, North Dakota, South Dakota, and Wyoming were initiated in 

1945. The studies were made as a part of the program of the Interior Department for development of the Missouri River Basin 

through funds provided directly to the Geological Survey for this 

purpose. The studies were made under the direction of P. C. 

Benedict, district engineer, Lincoln, Nebr. A few analyses of 

streams in the Hudson Bay Basin in North Dakota were made in 

connection with this program.

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 MartinDam, Colo., and on the Trinity River in Texas.

STREAM FLOW

Records of stream discharge, used in conjunction with the 

chemical analyses and determinations of sediment concentrations 

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 mean daily discharges 

or are instantaneous discharges for the particular times when the 

samples were collected.
