QUALITY OF SURFACE WATERS OF UNITED STATES, 1944
INTRODUCTION
The water analyses given on the following pages indicate the suita bility of the waters examined for industrial or agricultural use, and for domestic use so far as such use is affected by the dissolved or sus pended mineral matter in the waters. The samples for whkh analyt ical data are given were collected between October 1, 1943, and Sep tember 30, 1944.
Most of the analyses are of 10-day composites of daily samples col lected 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 dis charges 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 cer tain 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-inte grating 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 chem ical 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 publi cations 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 constit uents determined. In other analyses the quantity reported as dis solved 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 con ductance 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 approxi mately 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

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 evapora tion 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 bicarbon ate, sulfate, chloride, fluoride, nitrate, and dissolved sclids. Alumi num, 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 proper ties 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 con sumed 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 alka linity 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 conduct ance values are expressed in reciprocal ohms (mhos x 105) at 25° C. When considered hi conjunction with determinations for other con stituents, 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 man ganese 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 man ganese 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 quan tities 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 lime stone, 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, par ticularly from dolomitic rocks. Its effects are similar to those of cal cium. 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. Sul fate 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

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 contamina tion 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 appli cation 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 previousTy discussed. However, 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 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.
