QUALITY OF SURFACE WATERS OF THE 

UNITED STATES, 1945

INTRODUCTION

This volume is the fourth in a series of reports giving chemical 

analyses, suspended-sediment concentrations, and temperatures of the 

surface waters of the United States. The samples for which data are 

given were collected between October 1, 1944, and September 30,1945. 

Quantities of suspended sediment and water temperature were measured at some of the sampling stations. In July 1945, 48 daily-sampling stations for the study of the chemical character of surface waters 

were being maintained by the Geological Survey. Samples were 

collected less frequently during the year at many other points.

In order that, complete information may be readily available, 

descriptive statements are given for each station for which regular 

series of analyses 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 and hardness, and other pertinent data. Records of discharge of the streams 

for the sampling period are included in most tables of analyses.

The water analyses given on the following pages serve as a basis for 

determining the suitability of the waters examined for industrial or 

agricultural use and for domestic use insofar as such use is affected by 

the dissolved or suspended mineral matter hi 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 of some streams may change materially with relatively 

small variations in flow, whereas for other streams the chemical quality 

may remain relatively uniform throughout large ranges in discharge. 

The quantities of suspended sediment carried by streams also are 

related, to discharge, and during flood periods the sediment concentration in many streams may vary over a wide range.

COLLECTION AND EXAMINATION OF SAMPLES

Chemical quality. Samples for chemical analysis were collected 

daily at or near points on streams where gaging stations are maintained 

for measurement of discharge. Most of the analyses were made of 

10-day composites of daily samples collected for a period of a year at

1
2 QUALITY OF SURFACE WATERS, 1945

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 large changes in chemical composition, composite samples 

were made 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 1 are essentially the same or 

are modifications of methods described in recognized authoritative 

publications for the mineral analysis of water samples.

For those waters containing fairly 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. For streams in Iowa and for the Colorado 

River Basin, the reported suspended-sediment loads were computed 

from sediment concentrations determined in one or more sets of samples and the corresponding water discharge for each day. The U. S. 

D-43 depth-integrating sampler was used at the Grand Canyon and 

Bluff gaging stations in the Colorado River Basin, as well as in Iowa, 

for the collection of sediment samples from one to four times daily, 

depending on the rate of flow. Suspended-sediment concentrations 

reported with the analyses for Virginia, North Carolina, and Georgia 

were determined from the samples collected for chemical analysis 

and do not provide a reliable basis for computing the loads of suspended 

sediment carried by any of these streams.

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

estimated for those days on which no samples were collected. In 

addition to the records of total quantities of sediment, records of the 

sizes of the particles of sediment are included for some stations. Since 

much of the material carried in suspension can pass through the finest 

sieves, it is customary to determine the sizes of the smaller particles 

by the bottom withdrawal-tube method.2 As the sizes and settling

COLLECTION AND EXAMINATION OF SAMPLES 3

rates of the particles in suspension are affected by the chemical character of the water, the size analyses were made either with the native 

water or with a settling medium consisting of water similar in.character 

and concentration to the water of the original suspension. The concentration of suspended sediment in the bottom-withdrawal tube was 

often different from the concentration in the original suspension, but 

the weight of sediment used is indicated in the table of analyses.

Temperature. Daily river temperatures were obtained at some 

stations at the time the water samples were collected for chemical 

analysis. As far as was practicable, the water temperatures were 

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

station, in order that the data might 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. The thermometers used for the determination of 

water temperatures had a limit of accuracy of plus or minus 1°. Consequently, water temperatures as low as 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. Most analyses are also given in equivalents per 

million for those constituents entering into ionic balance. An equivalent per million is a unit chemical-combining weight of a constituent 

hi 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. 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 equivalent of calcium and magnesium except for samples 

collected in Pennsylvania, 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
4 QUALITY OF SURFACE WATERS, 1945

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

million of calcium, magnesium, sodium, and potassium and multiplying 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. 

: Specific-conductance values are expressed in reciprocal ohms 

(mhos x 10s at 25° C.). For convenience, the "mhos" are represented 

by "K" in the table of analyses. The discharge of the streams is 

reported in second-feet (see "Stream flow," p. 14) and the temperature 

in degrees Fahrenheit. Color is expressed in units of the platinumcobalt scale proposed by Hazen 3 in 1892. Hydrogen-ion concentration (pH) is given as the negative logarithm of the number of moles of 

ionized hydrogen per liter of water.

Average analyses (mathematical or weighted) for the water year 

are given for most daily-sampling stations. A mathematical-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. The weighted-average 

analysis represents approximately the composition of water that would 

be found in a reservoir containing all the water passing a given station 

during the year after thorough mixing in the reservoir. The weightedaverage 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.

Sediment concentrations for each day are expressed in percent by 

weight for streams in the Colorado River Basin, where concentrations 

in excess of 10 percent are not infrequent, and in parts per million 

by weight for all other streams for which sediment records are reported. 

One percent is equivalent to 10,000 parts per million.

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. The concentration of dissolved solids 

in a river water is frequently increased by drainage from mines or

1 Hazen, Alien, A new color standard for natural waters: Am. Chem. Jour., vol. 12, pp. 427-428,1892;
COMPOSITION OF SURFACE WATERS 5

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 a 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 in only negligible 

quantities in natural waters except in areas where the waters have 

been in contact with 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 (Mri). 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
6 QUALITY OF SURFACE WATERS, 1945

causes reddish-brown stains on white porcelain or enameled ware and 

fixtures and on clothing or other fabrics washed in the water.

Calcium (Co). Calcium is dissolved from practically all rocks, 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; many waters from 

limestone contain from 30 to 100 parts; and waters that have come 

in contact with deposits of gypsum may contain several hundred 

parts.

Magnesium (Mg). Magnesium is dissolved from many rocks, particularly from dolomitic rocks. Its effects are similar to those of 

calcium. The magnesium in soft waters may amount to only 1 part 

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 or more parts per million 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 (CO& and HCO^). 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 present in appreciable quantities in most 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 (SOi). Sulfate is dissolved from many rocks and soils in 

especially large quantities from gypsum and beds of shale. It is also 

formed by the oxidation of sulfides of iron and is therefore present in 

considerable quantities in waters from mines. Sulfate in waters that
COMPOSITION OF SURFACE WATERS 7

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 have 

several hundred parts per million of chloride that has been leached 

from the 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 present in some rocks 

to about the same extent as chloride. However, the quantity of 

fluoride present 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 usually present in the surface waters have no 

effect on the value of the water for ordinary uses, although 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.

Borate (B03). Boron has been found to be 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 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 thousands of parts 

per million of dissolved solids are sometimes successfully used for 

irrigation where irrigation practices permit the removal of soluble 

salts through the application of large volumes of water on well-drained 

lands.
8 QUALITY OP SURFACE WATERS, 1945

PROPERTIES AND CHARACTERISTICS OP WATER

Oxygen consumed. "Oxygen consumed" furnishes a rough indication of the oxidizable matter in the unaltered 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 water 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 a natural color of 200 to 300 or more.

Hydrogen-ion concentration (pPI). The degree of acidity or alkalinity of water, 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 toward 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 (KX.105 at 25° C.). The specific conductance of 

a water is a measure of its ability 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 with reference to industrial and domestic use. It is
COMPOSITION OF SURFACE WATERS 9

usually recognized by the increased quantity of soap required to 

produce lather. Hard water is 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 eriough 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 witji the use of water 

for many purposes except 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 w^ter represents the 

content of free carbon dioxide, mineral acids, and salts especially 

sulfates of iron and aluminum which hydrolyze to give hydrogen 

ions. Acid waters are very corrosive and generally contain excessive 

amounts of other objectionable constituents, such us iron, aluminum, 

or manganese.

Corrosiveness. The corrosiveriess of a water is tt at property which 

makes it 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. In addition, however, 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 th^,t cause corrosion.

In a general way, very soft waters of low mineral

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

of a water for irrigation. Waters in which the iercent sodium is

PUBLICATIONS

Chemical analyses, suspended-sediment loads, and water temperatures of samples of surface water made by the Geological Survey have 

been published annually since 1941. Records for the years ended 

September 30, 1941, 1942, 1943, and 1944, for many of the stations 

listed in this report are given in Water-Supply Papers 942, 950, 970, 

and 1022.

Geological Survey reports containing analyses of surface-water 

samples collected prior to 1941 are listed below. Publications dealing 

largely with the quality of ground-water supplies and only incidentally 

covering the chemical composition of surface-water supplies are not 

included.

14 QUALITY OF SURFACE WATERS, 1945

STREAM FLOW

Records of stream discharge used in conjunction with the analysesin 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 some analyses, the 

composite periods differ from the normal 10- or 11-day period and 

the discharges reported are the averages of the mean daily discharges 

either for the sampling days or 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.
