QUALITY OF SURFACE WATERS OF THE UNITED STATES, 1950

PARTS 1-4

INTRODUCTION .

The quality-of-water investigations of the United States Geo­ logical Survey are concerned with chemical and physical charac­ teristics of the surface and ground water supplies of the Nation. Most of the investigations carried on in cooperation with States and other Federal agencies deal with the amounts of matter in solution and in suspension in streams.

The records of chemical analyses, suspended sediment, and temperature for surface waters given in this volume serve as a basis for determining the suitability of the waters examined for industrial, agricultural, and 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 dis­ solved solids maybe expected during the periods of high flow than during periods of low flow. The concentration in some streams may change materially with relatively small variations in flow, whereas for other streams the quality may remain relatively uniform throughout large ranges in discharge. The quantities of suspended sediment carried by streams are also related to discharge, and during flood periods the sediment concentrations in many streams vary over wide ranges.

The regular yearly publication of records of chemical anal­ yses, suspended sediment, and water temperature was begun by the Geological Survey in 1941. The annual records prior to 1948 were published in a single volume for the entire country. Begin­ ning in 1948, the records were published in two volumes, and beginning in 1950, in four volumes, covering the drainage basins shown in figure 1. The samples for which data are given were collected from October 1, 1948, to September 30, 1949. De­ scriptive 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 hard­ ness, 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 ba­ sins, according to Geological Survey practice in reporting re­ cords of stream flow.

The shaded portion represents the section of the country covered by this volume; the unshaded portion repre­ sents the section of the country covered by other water- supply papers.

During the year ended September 30, 1950, 109 regular sam­ pling stations on 92 streams for the study of the chemical char­ acter of surface waters were maintained by the Geological Sur­ vey in the area covered by this volume. Samples were collected less frequently during the year at many other points. Water tem­ peratures were measured daily at 71 of the regular sampling sta­ tions. Not all analyses of samples of surface water collected during the year have been included. Single analyses of an incom­ plete nature generally have been omitted. Also, determinations made on the daily samples before compositing have not been re­ ported. 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 reference at the district of­ fices listed under Division of Work, on pages

Quantities of suspended sediment are reported for 13 sta­ tions during the year ended September 30, 1950. The sediment samples were collected from one to five times daily at most sta­ tions, depending on the rate of flow and changes in stage of the stream. Sediment samples were collected less frequently dur­ ing the year at many other points. In connection with measure­ ments of sediment discharge, sizes of sediment particles were determined at 10 of the stations. As noted under "Remarks" in

COLLECTION AND EXAMINATION OF SAMPLES 3

the table headings, suspended-sediment concentrations also were determined from the samples collected for chemical analysis in some parts of the country. 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 filtra­ tion plants utilizing these stream waters. Records of these in­ frequent determinations are, available for reference in the district offices listed.

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 term­ ed suspended sediment and generally constitutes the major part of the total sediment load. At the present time no reliable meth­ od has been developed for deter mining bed load on a routine basis.

COLLECTION AND EXAMINATION OF SAMPLES CHEMICAL QUALITY

Samples for chemical analysis were usually collected daily at, or near, points on streams where gaging stations are main­ tained for measurement of water discharge. Most of the analy­ ses 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 volumes 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 or concentration, samples were com­ posited for shorter periods on the basis of the concentration oi dissolved solids indicated by measurements of specific conduct­ ance of the daily samples.

The samples were analyzed according to methods regularly used by the Geological Survey. These methods are essentially the same as or are modifications of methods described in recog­ nized authoritative publications for the mineral analysis of water samples (Collins, 1928; Am. Public 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 analy­ ses the value reported as dissolved solids is the residue on evap­ oration after drying at 180° C for 1 hour. Specific conductance is given for most analyses and was determined by means of a con­ ductance bridge using a standard potassium chloride solution as reference.

QUALITY OF SURFACE WATERS, 1950

SUSPENDED SEDIMENT

In general, samples were collected daily with the. US D-43 depth-integrating sampler (U. S. Inter-agency, 1948, p. 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. Suspended-sediment samples, consisting of depth-integrated samples at three or more verticals in the cross section were made periodically to determine the cross-sectional distribution of the suspended concentration with respect to that at the daily sampling vertical. In streams where comparatively rap­ id fluctuations in transverse distribution of water discharge or sediment concentration are encountered at the sampling point, samples were taken regularly at two or more verticals to deter­ mine the average concentration across the section. During peri­ ods of high flow, samples were taken two or more times through­ out the day at many sampling stations, and during periods of rap­ idly changing flow samples were taken hourly at some stations.

Sediment concentrations were deter mined by filtration or evap­ oration 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 orig­ inal gage-height chart. The plotted concentrations adjusted, if necessary, for cross-sectional distribution with respect to that at the daily sampling vertical, were connected or averaged by continuous curves to obtain a concentration graph. This graph represented the estimated concentration at any time and, for most periods, mean daily concentrations were determined from the graph. When the concentration and water discharge were chang­ ing rapidly, the day was often subdivided for this computation. For some periods when the day-to-day variation in the concen­ tration was negligible, the data were not plotted, and the average concentration of the samples was used as the mean concentration for the day. For certain stations, when the discharge and sedi­ ment concentrations were relatively low and varied only slightly from day to day, the samples for a number of days were compos­ ited and the mean daily concentrations and mean daily loads are shown.

For some periods when no samples were collected, daily sedi­ ment loads were estimated on the basis of water discharge, sedi­ ment concentrations observed immediately preceding and follow­ ing the periods, and sediment loads for other periods of similar discharge. The estimates were further guided by weather condi­ tions and sediment discharge for other stations.

In many instances where there were no observations for sev­ eral days, the sediment loads for individual days are not esti­ mated, as numerous factors influencing the quantities of trans­ ported sediment made it very difficult to make accurate estimates of sediment loads for individual days. However, estimated sedi-

COLLECTION AND EXAMINATION OF SAMPLES 5

ment loads for missing days in an otherwise continuous period of sampling 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, rec­ ords of the particle sizes of sediment are included also. The particle sizes of the suspended sediments were determined peri­ odically for many of the stations. As much of the material car­ ried in suspension can pass through the finest sieves, the bottom- withdrawal tube method (U. S. Inter-agency, 1943, p. 82-90) was used in most of the analyses. Generally, sieves were used in the determination of particle sizes for sediments which were predominantly coarser than 0. 062 mm. Size distribution for some sediments was determined by a combination of sieves and pipette methods in which the size fraction 0.062 mm and larger was an­ alyzed by sieves and that smaller than 0. 062 mm was analyzed by the pipette method (Kilmer and Alexander, 1949). Native or distilled water, as noted in the tables of analyses, was used as the settling medium. In some instances, chemical dispersing agents were added to the settling medium. As settling diameters of the clay and colloidal fractions are of ten affected by the chem­ ical character of the settling medium, analyses made using na­ tive water more nearly simulate particle sizes existing in the stream. Results of analyses using distilled water or using a set­ tling medium containing dispersing agents approximate ultimate particle sizes of the finer fractions. The concentration of sedi­ ment suspension for analysis was reduced to less than 10,000 parts per million, where necessary, by means of a sample split­ ter, in order to stay within limits recommended for the bottom- withdrawal tube or pipette method. The concentration of sus­ pended 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 ob­ tained 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 unaffect­ ed by diurnal variations in temperature. For most large, swift­ ly 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. The thermometers used for determination of water temperature were accurate to plus or minus about 0. 5°F.

Records of thermograph observations consist of maximum and minimum temperatures for each day, the average of the max­ imum daily temperatures, and the average of the minimum daily temperatures.

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 although the expression of analyses in equiv­ alents per million is sometimes preferred. An equivalent per million is a unit chemical combining weight of a constituent in a million unit weights of water and is calculated by dividing the concentration in parts per million by the chemical combining weight of the constituent. For convenience in making this con­ version the reciprocals of chemical combining weights of the most commonly reported constituents (ions) are given in the fol­ lowing table:

Constituent Factor Constituent Factor

Iron (Fe++) .......... 0. 0358 Carbonate (CO3 ) .. 0. 0333Iron (Fe+++) ......... . 0537 Bicarbonate (HCO3 -) . 0164Calcium (Ca++) ...... . 0499 Sulfate (SO4"~)...... . 0208Magnesium (Mg++) .... 0822 Chloride (Cl~)...... . 0282Sodium (Na+) ........ .0435 Fluoride (F~) ...... . 0526Potassium (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 quan­ tity of sodium and potassium is given in some analyses and is the quantity of sodium needed in addition to the calcium and magne­ sium to balance the acid constituents.

The total hardness, as calcium carbonate (CaCO3), is calcu­ lated from the equivalents of calcium and magnesium except for a few samples for which the reported values also include equiv­ alents 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 quan­ tity of dissolved solids is given in tons per acre-foot as well as in parts per million. Per cent 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 com­ bined value, the value reported for percent sodium will include the equivalent quantity of potassium. In most waters of moder-

COMPOSITION OF SURFACE WATERS 7

ate to high concentration, the proportion of potassium is much smaller than that of sodium.

Specific conductance values are expressed in reciprocal ohms (micromhos at 25°C). The discharge of the streams is reported in second-feet (See Stream Flow, p. 20 ) and the temperature in degrees Fahrenheit. Color is expressed in units of the platinum- cobalt scale proposed by Hazen (1892, p. 427-428). Hydrogen- ion concentration (pH) is given as the negative logarithm of the number of moles of ionized hydrogen per liter of water.

An average of analyses (arithmetical or weighted) for the wa­ ter year is given for most daily sampling stations. An arith­ metical average 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 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 mix­ ing in the reservoir. The weighted average of the analyses is computed by multiplying the discharge for the sampling period by the quantities of the individual constituents for the corre­ sponding period and dividing the sum of the products by the sum of the discharges. Water as represented by the weighted aver­ age is less concentrated 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 dis­ solved solids.

Mean daily sediment concentrations are expressed in parts per million by weight. Daily sediment loads are expressed in tons per day, and except for subdivided days are usually ob­ tained by multiplying mean daily sediment concentration in parts per million by the mean daily discharge, and the conversion fac­ tor 0.0027.

Particle-size analyses are expressed in percentages finer than indicated sizes in millimeters. The size classification used in this report is that recommended by the American Geophysical Union Subcommittee on sediment terminology (Lane, et al; 1947, p. 937). Other data included as pertinent to the size analyses for many streams are the date of collection, the stream discharge and sediment concentration when sample was collected, the con­ centration of the suspension during analysis, and the method of analysis.

COMPOSITION OF SURFACE WATERS

All natural waters contain dissolved mineral matter. Water in contact with soils or rock, even for only a few hours, will dissolve some rock materials. The quantity of dissolved min­ eral matter in a natural water depends primarily on the type of rocks or soils through which the water has passed and the length

302255 O - 54 - 2

8 QUALITY OF SURFACE WATERS, 1950

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 char­ acter of their concentrated underground sources during dry peri­ ods and are more dilute during periods of heavy rainfall. Under­ ground 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 irri­ gated 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 to­ gether as scidium), bicarbonate, sulfate, chloride, fluoride, ni­ trate, boron, and dissolved solids. Aluminum, manganese, col­ or, pH, acidity, oxygen consumed, and other dissolved constit­ uents and physical properties are reported for certain streams. The source and significance of the different constituents and prop­ erties 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 scale; it usually is removed from feed water for high-pressure boilers. Silica also forms troublesome deposits on the blades of steam turbines.

Aluminum (Al)

Aluminum is usually present only in negligible quantities in natural waters except in areas where the waters have been in contact with the more soluble rocks of high aluminum content such as bauxite and certain shales. Acid waters often contain large amounts of aluminum. It may be troublesome in feed wa­ ters where it tends to be deposited as a scale on boiler tubes.

COMPOSITION OF SURFACE WATERS

Manganese (Mn)

Manganese is dissolved in appreciable quantities from rocks in some sections of the country. Waters impounded in large res­ ervoirs 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. Manga­ nese is not regularly determined in areas where it is not present in the waters in appreciable amounts. It is especially objection­ able 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 on fabrics and porcelain fixtures. Appre­ ciable quantities of manganese are often found in waters contain­ ing objectionable quantities of iron.

Iron (Fe)

Iron is dissolved from many rocks and soils. On exposure to the air, normal basic waters that contain more than 1 part per million of iron soon become turbid with the insoluble reddish fer­ ric oxide produced by oxidation. Surface waters, therefore, sel­ dom contain as much as 1 part per million of dissolved iron, although some acid waters carry large quantities of iron in solu­ tion. 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. Cal­ cium and magnesium make water hard and are largely respon­ sible for the formation of boiler scale. Most waters associated with granite or silicious sands contain less than 10 parts per million of calcium; waters in areas where rocks are composed of dolomite and limestone contain from 30 to 100 parts per mil­ lion; and waters that have come in contact with deposits of gyp­ sum may contain several hundred parts per million.

Magnesium (Mg)

Magnesium is dissolved from many rocks, particularly from dolomitic rocks. Its effect in water is similar to that of calcium. The magnesium in soft waters may amount to only 1 or 2 parts per million, but water in areas that contain large quantities of dolomite or other magnesium-bearing rocks may contain from 20 to 100 parts per million or more of magnesium.

10 QUALITY OF SURFACE WATERS, 1950

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 min­ eralized waters found in the western Untied States. Natural wa­ ters that contain only 3 or 4 parts per million of the two together are likely to carry almost as much potassium as sodium. As the total quantity of these constituents increases, the proportion of sodium becomes much greater. Moderate quantities of sodium and potassium have little effect on the usefulness of the water for most purposes, but waters that carry more than 50 or 100 parts per million of the two may require careful operation of steam boilers to prevent foaming. More highly mineralized waters that contain a large proportion of sodium salts may be unsatisfactory for irrigation.

Carbonate and bicarbonate (COS and 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 usually present in appreciable quantities in natural waters. The bicar­ bonate in waters that come from relatively insoluble rocks may amount to less than 50 parts per million; many waters from lime­ stone contain from 200 to 400 parts per million. Bicarbonate in moderate concentrations in water has no effect on its value for most uses. Bicarbonate or carbonate is an aid in coagulation for the removal of suspended matter from water.

Sulfate (S04)

Sulfate is dissolved from many rocks and soils in especially large quantities from gypsum and from beds of shale. It is form­ ed also by the oxidation of sulfides of iron and is therefore pre­ sent in considerable quantities in waters from mines. Sulfate in waters that contain much calcium and magnesium causes the for­ mation 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 con­ tain several hundred parts per million of chloride leached from soils and rocks, especially where the streams receive return drainage from irrigated lands or are affected by ground-water inflow carrying appreciable quantities of chloride. Large quan­ tities of chloride may affect the industrial use of water by in-

COMPOSITION OF SURFACE WATERS 11

creasing 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 com­ pared to that of chloride. 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. However, excess 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 (Dean, 1936, p. 1269-1272). This defect becomes increasingly noticeable as the quantity of fluoride in water increases above 1. 5 to 2.0 parts per million.

Nitrate (N0g)

Nitrate in water is considered a final oxidation product of ni­ trogenous 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 NOg) 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 crack­ ing 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 methemoglo- binemia in infants (Waring, 1949). In a report published by the National Research Council, Maxcy (1950, p. 271) concludes that a nitrate content in excess of 44 parts per million (as NO3) should be regarded as unsafe for infant feeding.

Boron (B)

Boron in small quantities has been found essential for plant growth, but irrigation water containing more thanl part per mil­ lion boron is detrimental to citrus and other boron-sensitive crops. Boron is reported in Survey 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.

12 QUALITY OF SURFACE WATERS, 1950

Dissolved solids

The reported quantity of dissolved solids the residue on evap­ oration--consists mainly of the dissolved mineral constituents in the water. It may also contain some organic matter and wa­ ter of crystallization. Waters with less than 500. parts per mil­ lion of dissolved solids are usually satisfactory for domestic and some industrial uses. Waters containing several thousand parts per million of dissolved solids are sometimes successfully used for irrigation where practices permit the removal of soluble salts through the application of large volumes of water on well-drained lands.

PROPERTIES AND CHARACTERISTICS OF WATER

Oxygen consumed

The value for oxygen consumed furnishes an approximation of the oxidizable matter in the unfiltered and filtered samples and gives a partial measure of polluting materials such as sew­ age and oxidizable industrial wastes. Naturally highly colored waters may have relatively high oxygen consumed, although wa­ ters that are not noticeably colored may contain oxidizable mate­ rial.

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 re­ moved. 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 sun­ light by the water molecules. Water for domestic use and some industrial uses should be free from any perceptible color. A color less than 10 usually passes unnoticed. Some swamp waters have natural color of 200 to 300 or more.

Hydrogen-ion concentration (pH)

The degree of acidity or alkalinity of water, as indicated by the hydrogen-ion concentration, expressed as pH, is related to the corrosive properties of water, and is useful in determining the proper treatment for coagulation that may be necessary at water-treatment plants. A pH value of 7. 0 indicates that the wa­ ter is neither acid nor alkaline. Waters having pH values pro­ gressively lower than 7.0 denote increasing acidity, whereas values progressively higher than 7.0 denote increasing alkalinity.

COMPOSITION OF SURFACE WATERS 13

(See p. 13 ). The pH of most natural surface waters ranges be­ tween 6 and 8. Some alkaline surface waters have pH values greater than 8. 0, and waters containing free mineral acid usually have pH values less than 4. 5.

Specific conductance (micromhos at 25 C)

The specific conductance of a water is a measure of its ca­ pacity to conduct a current of electricity. The conductance varies with the concentration and degree of ionization of the dif­ ferent 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 deter­ mination and plays an important part in indicating changes in concentration of the total quantity of dissolved minerals in sur­ face waters. (See p. 7 .)

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. The use of hard water is also objectionable because it contributes to the formation of scale in boilers, water heaters, radiators, and pipes, with the resultant decrease in rate of heat transfer, pos­ sibility 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 hard­ ness, 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 suit­ able for many purposes without further softening. Waters with hardness ranging from 61 to 120 parts per million may be con­ sidered moderately hard, but this degree of hardness does not seriously interfere with the use of water for many purposes ex­ cept for use in high-pressure steam boilers and in some indus­ trial processes. Waters with hardness ranging from 121 to 200 parts per million are considered hard, and laundries and indus­ tries may profitably soften such supplies. Water with hardness above 200 parts per million usually requires some softening be­ fore being used for most purposes.

Total acidity

The total acidity of a natural water represents the content of free carbon dioxide, mineral acids, and salts--especially sul- fates of iron and aluminum that hydrolyzeto give hydrogen ions. Acid waters are very corrosive and generally contain excessive amounts of objectionable constituents, such as iron, aluminum, and manganese.

14 QUALITY OF SURFACE WATERS, 1950

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 previ­ ously. Additionally, corrosion causes the deterioration of water pipes, steamboilers, and water-heating equipment. Many waters that do not appreciably corrode cold-water lines will aggressive­ ly attack hot-water lines. Oxygen, carbon dioxide, free acid, and acid-generating salts are the principal constituents in water that cause corrosion. In a general way, very soft waters of low mineral content tend to be more corrosive than hard waters con­ taining 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 suit­ ability of a water for irrigation. (See p. 6 .) Waters in which the percent sodium is more than 60 may be injurious when ap­ plied to certain types of soils, particularly when adequate drain­ age is not provided (Magistid and Christiansen, 1944, p. 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. Sus­ pended 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 geo­ logic cycle of rock transformation. In some instances, this nor­ mal process may have been accelerated by agricultural prac­ tices. Sediment also results from a number of industrial activ­ ities. 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 trans­ portation, is affected by climatic conditions, form or nature of precipitation, vegetal cover, topography, and land use. An im­ portant property of fluvial sediment is the fall velocity of the particles in transport. Particle sizes, as determined by*various

PUBLICATIONS 15

methods, represent mechanical diameters, which are related to sedimentation diameters indirectly. Sediment particles in the sand-size (0.062 mm) range do not appear to be affected by floc- culation 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 on 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 on 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 veloc­ ity 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.

PUBLICATIONSReports giving chemical analyses, suspended-sediment loads,

and water temperatures of samples of surface water made by the Geological Survey have been published yearly since 1941. Records for the years ended September 30, 1941, 1942, 1943, 1944, 1945, 1946, 1947, 1948, and 1949, for many of the stations listed in this report are given in Water-Supply Papers 942, 950, 970, 1022, 1030, 1050, 1102, 1132, and 1162.

Geological Survey reports containing analyses of surface- water samples collected prior to 1941 are listed below. Publi­ cations dealing largely with the quality of ground-water supplies and only incidentally covering the chemical composition of surface - waters are not included.

20 QUALITY OF SURFACE WATERS, 1950

logical Survey for quality-of-water investigations.Assistance in collecting records was given by many municipal,

State, and Federal agencies.

DIVISION OF WORKThe quality-of-water program was conducted by the water re­

sources 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 prepared for pub­ lication under the supervision of the following: In Florida, S. K. Love; in North Carolina and South Carolina, F. H. Pauszek; in Virginia, G. W. Whetstone; in Ohio, W. L. Lamar; and in Del­ aware and Pennsylvania, W. F. White. Any additional analyt­ ical data on file can be obtained by writing the responsible Sur­ vey district office.

STREAM FLOW

Most of the records of stream discharge, used in conjunction with the chemical analyses and in the computation of sediment loads in this volume, arb 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 tiiean daily discharges for the normal composite period. For a- nalyseS 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 dis­ charges reported in the tables of single analyses either are daily mean discharges or are discharges for the time at which samples were collected, computed from a stage -discharge relation or from a discharge measurement.
