QUALITY OF SURFACE WATERS OF 

UNITED STATES, 1944

INTRODUCTION

The water analyses given on the following pages indicate the suitability of the waters examined for industrial or agricultural use, and 

for domestic use so far as such use is affected by the dissolved or suspended mineral matter in the waters. The samples for whkh analytical data are given were collected between October 1, 1943, and September 30, 1944.

Most of the analyses are of 10-day composites of daily samples collected for a period of a year at a sampling point. The samples were 

generally taken at points where gaging stations are maintained for 

measurement of discharge. 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. For these analyses, 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 are either mean daily discharges or are instantaneous discharges for the particular times when 

the samples were collected.

In addition to the tables of chemical analyses, records of rnspended 

sediment loads and of daily water temperatures are included for certain rivers. The reported suspended sediment loads were computed 

from sediment concentrations determined in one or mor^ sets of 

samples collected daily and from the water discharge. The Colorado 

River type of depth-integrating sampler was used on streams in the 

Colorado River Basin throughout the year with two exceptions. The 

US D-43 depth-integrating sampler was used on the San Juan River 

near Bluff, Utah, beginning May 1 and on the Colorado Fiver near 

Grand Canyon, Ariz., beginning June 1. The US D-43 depth-integrating sampler was used on Iowa streams in collecting sediment 

samples from one to four times daily, depending on the rate of flow. 

Daily river temperatures are given for a few streams. T^ ase data 

were obtained at the time the water samples were collected for chemical analysis. So far as practicable the water temperatures were 

observed at about the same time each day for each river station.

ANALYTICAL METHODS

CHEMICAL ANALYSES

Three composite samples were usually analyzed each month. These 

samples were made by mixing together equal qu;antHies 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 at times made for shorter periods on the basis of the 

concentration ol dissolved solids indicated by measurements of specific 

conductance of the daily samples.

i The samples were analyzed according to methods that are regularly 

used by the Geological Survey and that are essentially tl ?- same or are 

modifications of methods described in recognized authoritative publications 1 for the mineral analysis of water samples. The mineral 

constituents are reported in parts per million and also in equivalents 

per million for most analyses. Results given in parts per million 

can be converted to grains per United States gallor by dividing 

by 17.12.

The constituents determined were not the same for all areas. In the 

analyses of some waters used for irrigation the quantity of dissolved 

solids is given in tons per acre-foot as well as in parts per million. 

These analyses also give the percent sodium. In analyses of waters 

containing fairly large quantities of soluble salts the quantity reported 

for dissolved solids is the sum of the quantities of the various constituents determined. In other analyses the quantity reported as dissolved solids is the residue on evaporation after heating at 180° C. for 

1 hour. The total hardness is calculated as the CaCO3 equivalent of 

all the significant cations except sodium and potassium. In some of 

the analyses noncarbonate hardness is also reported. Specific conductance is given for most analyses and was determined by means of a 

conductance bridge using a standard potassium chloride solution as 

reference.

Average or weighted-average analyses for the water year are given 

for most daily sampling stations. An 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 the water passing a given station during the year after 

thorough mixing hi the reservoir. The weighted-average analysis is

Cd., pp. 53-123,1936.
. ANALYTICAL METHODS 3

computed by multiplying the discharge for the sampling per od by the 

quantities of the individual constituents for the corresponding period 

and dividing the sum of the products by the total discharge for the 

water year. The weighted-average analysis shows less-cor^entrated 

water than that represented by the average of the individua 1 analyses 

because at times of high discharge the rivers carry the smallest amount 

of dissolved solids.

SUSPENDED SEDIMENT

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

were interpolated for those days on which no samples were collected. 

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.

In addition to these records of total quantities of sedimert, records 

of the sizes of the particles of sediment are included as a guide to 

estimating the volumes of deposited material. Since much of the 

material carried in suspension is smaller than 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 the settling rates of the 

particles in suspension are dependent on the chemical character of the 

water, the size analyses were made with a settling medium consisting 

of water similar in character and concentration to the water of the 

original suspension.

MINERAL, CONSTITUENTS IN SOLUTION

All natural waters contain dissolved mineral matter. Water in 

contact with soils or rocks, even for only a few hours, will dissolve 

the rock minerals. The quantity of dissolved mineral matter in a 

natural water depends primarily on the type of rocks or soil-- through 

which the water has passed and the length of time it has been in contact 

with the rocks or soils. The concentration of mineral matter in a 

river water is frequently increased by drainage from mines or oil 

fields, by the addition of industrial or municipal wastes, or by return 

drainage in irrigated regions.

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 data for silica, iron, calcium, magnesium, sodium,

potassium or sodium and potassium together as sodium bicarbonate, sulfate, chloride, fluoride, nitrate, and dissolved sclids. Aluminum, manganese, color, hydrogen-ion concentration (pH), acidity, 

oxygen consumed, and borate are reported for certain streams. The 

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

Oxygen consumed. The term "oxygen consumed" furrishes a rough 

indication of the oxidizable organic matter in the unfilterrd and filtered 

samples. Oxygen consumed may be roughly proportional to the 

intensity of the color of natural waters, though waters that are not 

noticeably colored may contain oxidizable material. Oxygen consumed gives a partial measure of polluting materials sr o,h as sewage 

and oxidizable industrial wastes.

Color. In water analysis the term "color" refers to tl °> appearance 

of water that is free from suspended solids. Water for domestic use 

and some industrial uses should be free from any perceptible color. 

Color in natural surface waters is due almost entirely to organic matter 

extracted from leaves, roots, and decaying plant life on the ground 

and hi the soils. At some localities high color in water results from 

industrial wastes and sewage. A color less than 10 usually passes 

unnoticed. Some swamp waters have natural color of 200 or 300 

or more.

Hydrogen-ion concentration (pH). The degree of acidity or alkalinity of water, as indicated by the hydrogen-ion concentration, or 

pH, is related to the corrosive properties of water, and should be 

known so that proper treatment for coagulation may be made at 

water-treatment plants. It represents .the negative logarithm of the 

number of moles of ionized hydrogen per liter of water. A pH value 

of 7.0 indicates that the water is neither acid nor alkdine. Values 

lower than 7.0 denote increasing acidity, while values higher than 7.0 

denote increasing alkalinity. The pH of water indicates its activity 

towards metal surfaces. As the pH increases the corrosive activities 

of the water decreases. The pH of most natural STirface waters 

varies between 6.0 and 8.0. Some alkaline surface waters have pH 

values greater than 8.0, and waters containing free minerrl acid usually 

have values less than 4.5.

Specific conductance (KX105 at 25° <?.). The specific conductance of 

water is a measure of its ability to conduct a current of electricity. 

It varies with the temperature and with the concentration and degree 

of ionization of the different minerals in solution. Specific conductance values are expressed in reciprocal ohms (mhos x 105) at 25° C. 

When considered hi conjunction with determinations for other constituents, specific conductance is a useful determination and plays
MINERAL CONSTITUENTS IN SOLUTION 5

an important part in following changes in concentration of the total 

. quantity of dissolved minerals in surface waters.

Silica (Si02). Silica is dissolved from practically all rocl*?*. A few 

natural surface waters contain less than 3 parts per million of silica 

and some 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 and 

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

also forms troublesome deposits on the blades of steam turbines.

Aluminum and manganese (Al and Mri). Aluminum and manganese are dissolved in appreciable quantities from rock? 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 the action of carbon dioxide produced by 

anaerobic fermentation of organic matter. Aluminum and manganese are not regularly determined in areas where these constituents 

are not present in appreciable quantities. Acid waters mry contain 

relatively large quantities, which can be troublesome in certain uses 

of the waters. Manganese is especially objectionable in vater used 

in laundry work and in textile processing. It causes a dark-brown or 

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

quantities of iron.

Iron (Fe). Iron is dissolved from many rocks and soils. On 

exposure to the air, normal basic waters that contain mere than 1 

part per million of iron soon become turbid with the insolut'e 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 cany large quantities of iron in solution. Iron causes 

stains on white porcelain or enameled ware and fixtures and on clothing 

or other fabrics washed hi the water.

Calcium (Co). Calcium is dissolved from practically all rocks, but 

is usually found in greater quantities in waters 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 may contain less than 

10 parts per million of calcium; many waters from limestone contain 

from 30 to 100 parts; and waters that leach 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 or 2 parts 

per million, but water in areas that contain large quantities of dolomite
6 QUALITY OF STJRFACE WATERS, 1944

or-other magnesium-bearing rocks may contain from 20 tc 100 or more 

parts per million of magnesium.

Sodium and potassium (Na and K). Sodium and potassium are 

dissolved from practically all rocks, but they make up only a small part 

of the dissolved mineral matter in most surface waters in humid 

regions. Sodium may be the predominant basic radical in more highly 

mineralized waters found in some sections of 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 greater. Moderate quantities of these constituents 

have little effect on the usefulness of the water for most pirposes, 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. Waters 

that contain a large proportion of sodium salts may not be satisfactory 

for irrigation, and a few waters contain so much sodium that they are 

unfit for nearly all uses.

Carbonate and bicarbonate (COz and HCO^). Bicarbonate occurs in 

waters largely through the action of carbon dioxide, whicl enables the 

water to dissolve carbonates of calcium and magnesium. Carbonate 

is not present in appreciable quantities in most natural waters. The 

bicarbonate in waters that come from relatively insoluble rocks may 

amount to 50 parts per million or less; many waters from limestone 

contain from 200 to 400 parts per million. Bicarbonate in moderate 

quantities in water has no effect for most uses.

Sulfate (SO*). Sulfate is dissolved from rocks and soils and in large 

quantities from gypsum in beds of shale and from deposits of sodium 

sulfate. 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 contain much calcium and magnesium causes the 

formation of hard scale in steam boilers and may increase the cost of 

softening the water.

Chloride (CZ). Chloride is dissolved from rock materials in all parts 

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

chloride, while streams in arid or semiarid regions may have several 

hundred parts per million of sodium chloride that has Hen leached 

from the soils and rocks, especially where they 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 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 known to be associated with the
MINERAL CONSTITUENTS IN SOLUTION 7

dental defect known as mottled enamel, if the water is used fc ^ drinking 

by young children during calcification or formation of the teeth. This 

condition becomes more noticeable as the quantity of fluorine in water 

increases above 1 part per million. Present investigations indicate 

that the incidence of dental caries decay of teeth is less Vhen there 

are small amounts of fluoride present in the water supply than when 

there is none.

Nitrate (NOZ). Nitrate in water is considered a final oxidation 

product of nitrogenous material and may indicate previous contamination by sewage or other organic matter. The quantities of nitrate 

usually present in surface waters have no effect on the vahn of water 

for ordinary uses, though it has been reported that as much as 2 parts 

per million of nitrate prevent intercrystalline cracking of boiler steeL

Borate (B03). Borate is reported for analyses of most surface waters 

in arid and semiarid regions of the middle and far west, where irrigation 

is practiced or contemplated. The element boron (B) has t ^en found 

to be detrimental to citrus and certain other crops. Very few of the 

surface waters analyzed have been found to contain boron in harmful 

concentrations.

Dissolved solids. The quantity reported as dissolved solids the 

residue on evaporation consists mainly of the dissolved mineral 

constituents in the water. It also may 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 with more than 1,000 parts per 

million of dissolved solids are likely to be unsuitable for most domestic 

and industrial uses. Waters containing several thousands of parts 

per million are sometimes successfully used for irrigation where 

irrigation practices permit removal of soluble salts through the application of large volumes of water on well-drained lands.

.Hardness. Hardness is the characteristic of water that receives 

the most attention with reference to industrial and domestic use. 

It is usually recognized by .the increased quantity of soap required 

to produce lather and by the deposits of insoluble salts formed when 

water is heated.

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. Hardness is 

expressed as the calcium carbonate equivalent of all the rignificant 

Rations except sodium and potassium. The hardness caused by 

calcium, magnesium, and other ions equivalent to the bicarbonate 

or carbonate in a water is called carbonate hardness; the hardness 

caused by other compounds of calcium and magnesium is called 

noncarbonate hardness. Water that has less than 60 parts p er million
8 QUALITY OF SURFACE WATERS, 1944

of hardness is usually rated as soft and suitable for most purposes 

without further softening. Hardness between 60 and 120 parts per 

million does not seriously interfere with the use of water for most 

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 

beyond 200 parts per million usually requires some treatment for 

removal of hardness 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 sails, 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 as iror, aluminum, 

or 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 "red water" caused by solution of iron. 

The disadvantages of iron in water have been previousT y discussed. 

However, besides the trouble caused by iron in water, corrosion 

causes the deterioration of water pipes, steam boilers, and waterheating equipment. Many waters that do not appreciably corrode 

cold-water lines will aggressively attack hot-water linos. 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 coTosive than 

hard waters containing appreciable quantities of the 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 westerr part of the 

country where irrigation is practiced extensively. The proportion 

of sodium to other basic constituents in the water has a bearing on 

the suitability of a water for' irrigation. It is the result obtained 

bp dividing the equivalents per million of sodium by the equivalents 

per million of the cations (usually calcium, magnesium, sodium, and 

potassium) and multiplying by 100. 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.
