QUALITY OF SURFACE WATERS 

OF THE UNITED STATES, 1956

PARTS 7 and 8

INTRODUCTION

The quality-of-water investigations of the United States Geological Survey are concerned with chemical and physical characteristics 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 analysis, 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 dissolved 

solids may be 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.

Publication of annual records of chemical analyses, suspended 

sediment,and water temperature was begun by the Geological Survey 

in 1941. The records prior to 1948 were published each year in a 

single volume for the entire country. Beginning 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 in this volume were collected 

from October 1, 1955, to September 30, 1956. The records are 

arranged by drainage basins according to Geological Survey practice in reporting records of streamflow: Stations on tributary

streams are listed between stations on the main stem in the order 

in which those tributaries enter the main stem. Descriptive statements are given for each sampling station for which regular series 

of chemical analyses, temperature observations, 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 mineralization, 

hardness, water temperature, sediment loads, and other pertinent 

data. Records of water discharge of the streams at or near the 

sampling period are included in most tables of analyses.

During the year ending September 30,1956, 157 regular sampling stations on 95 streams for the study of the chemical character 

of surface waters were maintained by the Geological Survey in the 

area covered by this volume. Samples were collected less frequently during the year at many other points. Water temperatures 

were measured daily at 82 stations. Not all analyses of samples 

of surface water collected during the year nave been included. 

Single analyses of an incomplete nature generally have been omitted. Also, analyses made of the daily samples before compositing have not been reported. The specific conductance of almost 

all daily samples was determined, and as noted in the table head-
COLLECTION AND EXAMINATION OF SAMPLES 3

ings this information is available for reference at the district offices listed under Division of Work, on page 22.

Quantities of suspended sediment are reported for 24 stations 

during the year ending September 30, 1956. The sediment samples 

were collected one or more times daily at most stations, depending 

on the rate of flow and changes in stage of the stream. Sediment 

samples were collected less frequently during the year at many 

other points. In connection with measurements of sediment discharge, sizes of sediment particles were determined at 21 of the 

stations.

Material which is transported almost in continuous contact with 

the stream bed and the material that bounces along the bed in short 

skips or leaps is termed "bed load" and is not considered in this 

report. All other undissolved fragmental material in transport is 

termed "suspended sediment" and generally constitutes the major 

part of the total sediment load. At the present time no reliable 

routine method has been developed for determining bed load.

COLLECTION AND EXAMINATION OF SAMPLES 

CHEMICAL QUALITY

Samples of chemical analyses were usually collected at or near 

points on streams where gaging stations are maintained for measurement of water discharge. Two methods of compositing water 

samples for analysis are used by the Geological Survey: (1) Equal 

volume method 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 from 

the 21st to the end of the month. Composite samples were prepared for shorter periods if the specific conductance of the daily 

samples indicated that the mineral content of the water had changed 

significantly. Conversely, composite samples were occasionally 

prepared for longer periods if the specific conductance of the daily 

samples indicated that the mineral content had remained nearly 

uniform. (2) Discharge method Composite samples were prepared by mixing together a volume from each sample in proportion 

to the product of the rate of water discharge at the time of sampling and the time interval represented by that sample. Generally, 

each daily sample is assumed to represent an equal time interval; 

therefore, the volume from each sample is proportional only to the 

water discharge at the time of sampling. Compositing samples by 

the discharge method was limited to some streams west of the 

Mississippi River.

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 recognized authoritative publications for the mineral analysis of water samples 

(Collins, 1928; Am. Public Health Assoc., 1955).
QUALITY OF SURFACE WATERS, 1956

TEMPERATURE

Daily water temperatures were measured at most of the stations when chemical quality or sediment samples were collected. 

So far as practicable, the water temperatures were taken at about 

the same time each day for an individual station in order that the 

data would be relatively unaffected by diurnal variations in temperature. Most large, swiftly flowing streams probably have a 

small diurnal variation in water temperature, whereas sluggish 

or shallow streams may have a daily range of several degrees and 

may follow closely the changes in air temperature. The thermometers used for determining water temperature were accurate to 

plus or minus 0.5°F.

At stations where thermographs are located, the records consist of maximum and minimum temperatures for each day, and the 

monthly averages of maximum daily and minimum daily temperatures .

SEDIMENT

In general, suspended-sediment samples were collected daily 

with U. S. depth-integrating cable-suspended samplers (U. S. Interagency, 1948, p. 70-76 and U. S. Interagency, 1952, p. 86-90) 

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. Depth-integrated samples were collected periodically at three or more verticals in the cross section to determine the cross-sectional distribution of the concentration of suspended sediment with respect to that at the daily sampling vertical. 

In streams where transverse distribution of sediment concentration 

ranges widely, samples were taken regularly at two or more verticals to determine the average concentration across the section. 

During periods of high flow, samples were taken two or more times 

throughout the day at many sampling stations, and during periods 

of rapidly changing flow samples were taken hourly at some stations.

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

mean concentration for some days was obtained by plotting the instantaneous concentrations on the original or copies of the original 

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
COLLECTION AND EXAMINATION OF SAMPLES 5

to obtain a concentration graph. This graph represented the estimated concentration at anytime and, for most periods, daily mean 

concentrations were determined from the graph. When the concentration and water discharge were changing rapidly, the day was 

often subdivided for this computation. For some periods when the 

day-to-day variation in the concentration was negligible, the data 

were not plotted, and the average concentration of the samples 

was used as the mean concentration for the day. For certain stations, when the discharge and concentrations were relatively low 

and varied only slightly from day to day, the samples for a number 

of days were composited and the mean daily concentrations and 

mean daily loads are shown.

For some periods when no samples were collected, daily loads 

of suspended sediment were estimated on the basis of water discharge, sediment concentrations observed immediately preceding 

and following the periods, and suspended-sediment loads for other 

periods of similar discharge. The estimates were further guided 

by weather conditions and sediment discharge for other stations.

In many instances where there were no observations for several days, the suspended-sediment loads for individual days are 

not estimated, because numerous factors influencing the quantities 

of transported sediment made it very difficult to make accurate 

estimates for individual days. However, estimated loads of suspended sediment for missing days in otherwise continuous period 

of sampling have been included in monthly and annual totals for 

most streams to provide a complete record. For some streams, 

samples were collected about weekly, monthly, or less frequently, 

and only rates of sediment discharge at the time of sampling are 

shown.

In addition to the records of quantities of suspended sediment 

transported, records of the particle sizes of sediment are included. 

The particle sizes of the suspended sediments for many of the stations, and the particle sizes of the bed material for some of the 

stations were determined periodically. As much of the material 

carried in suspension is finer than 0.062 mm, the pipet method 

(Kilmer and Alexander, 1949) or the bottom withdrawal tube method 

(U. S. Interagency, 1943, R. 82-90) were used in most of the analyses. For most samples, material between 1.0 mm and 0.062 mm 

was analyzed by the visual accumulation tube method (U. S. Interagency 1957). Separation of sand from the silt-clay-colloid fraction was by sieve. For some samples all sediment coarser than 

0.062 mm was analyzed by the sieve method. For material finer 

than 0.062 mm the settling medium used was native water or distilled water to which a dispersing agent had been added. Because 

sedimentation diameters of the clay and colloidal fractions are 

often affected by the chemical character of the settling medium, 

analyses made with native water may more nearly simulate particle sizes existing in the stream. Results of analyses with dis540653 O -60 -2
6 QUALITY OF SURFACE WATERS, 1956

tilled water containing a dispersing agent approximate ultimate 

particle sizes of the finer fractions. The concentration of sediment suspension for analysis was reduced to less than 5,000 parts 

per million where necessary by means of a sample splitter, in 

order to stay within limits recommended for the bottom-withdrawal 

tube or pipet method; therefore, the concentration of sediment for 

analyses was often different from the concentration in the stream. 

The concentration at which analyses were made is indicated in the 

appropriate tables.

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 equivalents 

per million is sometimes preferred. An equivalent per million is 

a unit chemical combining weight of a constituent in a million unit 

weights of water. Equivalents per million are calculated by dividing the concentration in parts per million by the chemical combining weights of the individual constituents. For convenience in 

making this conversion the reciprocals of chemical combining 

weights of the most commonly reported constituents (ions) are 

given in the following table:

Constituent Factor Constituent Factor

Iron (Fe++)..........0.0358 Carbonate (CO 3 ~~) ..0.0333

Iron (Fe+++)......... . 0537 Bicarbonate (HCO 3 -). . 0164

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

Magnesium (Mg++) ... .0822 Chloride (Cl-)....... .0282

Sodium (Na+) ........ .0435 Fluoride (F~) ....... .0526

Potassium (K+) ...... .0256 Nitrate (CO3 ')...... .0161

Results given in parts per million can be converted to grains 

per United States gallon by dividingby 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 constituents.

The hardness, expressed in terms of an equivalent quantity of 

calcium carbonate (CaCO3 ), is calculated from the equivalents of 

calcium and magnesium, or is determined by direct titration. The 

hardness caused bycalciumand 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.

The value usually reported as dissolved solids is the residue

on evaporation after drying at 180° C for 1 hour. For some waters, 

particularly those containing moderately large quantities of soluble 

salts, the value reported is calculated from the quantities of the 

various determined constituents using the carbonate equivalent of 

the reported bicarbonate. The calculated sum of the constituents 

may be given instead of or in addition to the residue. 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 is computed for those analyses where sodium 

and potassium are reported separately by dividing the equivalents 

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

calcium, magnesium, sodium, and potassium and multiplying the 

quotient by 100. In analyses where sodium and potassium were 

calculated and reported as a combined value, the value reported 

for percent sodium will include the equivalent quantity of potassium. In most waters of moderate to high concentration the proportion of potassium is much smaller than that of sodium.

Specific conductance is given for most analyses and was determined by means of a conductance bridge and using a standard 

potassium chloride solution as reference. Specific conductance 

values are expressed in micro mhos per centimeter at 25° C. Specific conductance in micromhos is 1 million times the reciprocal 

of specific resistance at 25°C. Specific resistance is the resistance in ohms of a column of water 1 centimeter long and 1 square 

centimeter in cross section. The discharge of the streams is 

reported in cubic feet per second (see Streamflow, p. 17 ) 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 is expressed in terms of pH units. By 

definition the pH value of a solution is the negative logarithm of 

the concentration of gram ions of hydrogen. However, the pH meter 

that is generally used in Survey laboratories determines the activity of the hydrogen ions a§ distinguished from concentration.

An average of analyses for the water year is given for most 

daily sampling stations. Most of these averages are arithmetical 

or time-weighted; when analyses during a year are all on 10-day 

composites of daily samples with no missing days, the arithmetical 

and time-weighted averages are equivalent. A time-weighted 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 discharge-weighted 

average approximates the composition of water that would be found 

in a reservoir containing all of the water pass ing a given station during the year after thorough mixing in the reservoir. A dischargeweighted average is computed by multiplying the discharge for the 

samp ling period by the concentrations of the individual constituents 

for the corresponding period and dividing the sum of the products
8 QUALITY OF SURFACE WATERS, 1956

by the sum of the discharges. Discharge-weighted averages are 

usually lower than arithmetical averages for most streams because at times of high discharge the rivers generally have lower 

concentrations of dissolved solids.

The concentration of sediment in parts per million is computed 

as 1, 000,000 times the ratio of the weight of sediment to the weight 

of water-sediment mixture. Daily sediment loads are expressed in 

tons per day and except for subdivided days are usually obtained by 

multiplying daily mean sediment concentration in parts per million 

by the daily mean discharge, and the appropriate conversion factor, normally 0.0027.

Particle-size analyses are expressed in percentages of material 

finer than indicated sizes in millimeters. The size classification 

used in this report is that recommended by the American Geophysical Union subcommittee on Terminology (Lane and others, 

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 

concentration 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 mineral 

matter in a natural water depends primarily on the type of rocks 

or soils with which the water has been in contact and the length of 

time of contact. Some streams are fed by both surface runoff and 

ground water from springs or seeps. Such streams reflect the 

chemical character of their concentrated underground sources during dry periods and are more dilute during periods of heavy rainfall. Ground water is generally more highly mineralized than surface runoff because it remains in contact with the rocks and soils 

for much longer periods. The concentration of dissolved solids in 

a river water is frequently increased by drainage from mines or 

oil fields, by the addition of industrial or municipal wastes, or-- 

in irrigated regions by drainage from irrigated lands.

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

acidity, oxygen consumed, and other dissolved constituents and 

physical properties are reported for certain streams. Phenolic
COMPOSITION OF SURFACE WATERS 9

material and minor elements including strontium, chromium, nickel, copper, lead, zinc, cobalt, arsenic, cadmium, and others are 

occasionally determined for a few streams in connection with specific problems in local areas and the results are reported when appropriate . The source and significance of the different constituents 

and properties of natural waters are discussed in the following 

paragraphs.

MINERAL CONSTITUENTS IN SOLUTION 

Silica (SiO2 )

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 most waters contain from 

1 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 stream turbines.

Aluminum (Al)

Aluminum is generally 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 maybe troublesome in feed waters where it tends 

to be deposited as a scale on boiler tubes.

Manganese (Mn)

Manganese is dissolved in appreciable quantities from rocks 

in some sections of the country. Waters impounded in large reservoirs may contain manganese that has been dissolved from the 

mud on the bottom of the reservoir by action of carbon dioxide 

produced by anaerobic fermentation of organic matter. Manganese 

is not regularly determined in areas where it is not present in the 

waters inappreciable amounts. It is especially objectionable in 

water used in laundry work and in textile pr bees sing. Concentrations as low as 0.2 part per million may cause a dark-brown 

or black stain on fabrics and porcelain fixtures. Appreciable quantities of manganese are often found in waters containing objectionable quantities of iron.
10 QUALITY OF SURFACE WATERS, 1956

Iron (Fe)

Iron is dissolved from many rocks and soils. On exposure to 

the air, normal basic waters that contain more than 1 partper million of iron soon become turbid with the insoluble reddish ferric 

oxide produced by oxidation. Surface waters, therefore, seldom 

contain as much as 1 part per million of dissolved iron, although 

some acid waters carry large quantities of iron in solution. Iron 

causes reddish-brown stains on white porcelain or enameled ware 

and fixtures and on fabrics washed in the water.

Calcium (Ca)

Calcium is dissolved from almost all rocks and soils, but the 

highest concentrations are usually found in waters that have been 

in contact with limestone, dolomite, and gypsum. Calcium and 

magnesium make water hard and are largely responsible for the 

formation of boiler scale. Most waters associated 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 million; and waters that 

have come in contact with deposits of gypsum may contain several 

hundred parts per million.

Magnesium (Mg)

Magnesium is dissolved from many rocks, particularly from 

dolomitic rocks. Its effect in water is similar to that of calcium. 

The magnesium in soft waters may amount to only 1 or 2 parts per 

million, but water in areas that contain large quantities of dolomite 

or other magnesium-bear ing rocks may contain from 20 to 100 

parts per million or more of magnesium.

Sodium and potassium (Na and K)

Sodium and potassium are dissolved from almost 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
COMPOSITION OF SURFACE WATERS 11

boilers to prevent foaming. More highly mineralized waters that 

contain a large proportion of sodium salts may be unsatisfactory 

for irrigation.

Carbonate and bicarbonate (CO3 and HCO3 )

Bicarbonate occurs in waters largely through the action of 

carbon dioxide, which enables the water to dissolve carbonates 

of calcium and magnesium. Carbonate as such is not usually present in appreciable quantities in natural waters. The bicarbonate 

in waters that come from relatively insoluble rocks may amount to 

less than 50 parts per million; many waters from limestone contain from 200 to 400 parts per million. Bicarbonate in moderate 

concentrations in water has no effect on its value for most uses. 

Bicarbonate or carbonate is an aid in coagulation for the removal 

of suspended matter from water.

Sulfate (SO4 )

Sulfate is dissolved from many rocks and soils but in especially 

large quantities from gypsum and from beds of shale. It is formed 

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

considerable quantities in waters from mines. Sulfate in waters 

that contain much calcium and magnesium causes the formation of 

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

the water.

Chloride (Cl)

Chloride is dissolved from rock materials in all parts of the 

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

chloride content, whereas streams in arid or semiarid regions 

may contain several hundred parts per million of chloride leached 

from soils and rocks, especially where the streams receive return drainage from irrigated lands or are affected by ground-water 

inflow carrying appreciable quantities of chloride. 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 being present in some rocks in 

about the same amount as chloride. However, the quantity of
12 QUALITY OF SURFACE WATERS, 1956

fluoride in natural surface waters is ordinarily very small compared 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 (NO 3 )

Nitrate in water is considered a final oxidation product of nitrogenous material and may indicate contamination by sewage or 

other organic matter. The quantities of nitrate present in surface 

waters are generally less than 5 parts per million (as NO3 ) and 

have no effect on the value of the water for ordinary uses.

It has been reported that as much as 2 parts per million of nitrate in boiler water tends to decrease intercrystalline cracking 

of boiler steel. Studies made in Illinois indicate that nitrates in 

excess of 70 parts per million (as NO3 ) may contribute to methemoglobinemia ("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 cause methemoglobinemia (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 NO 3 ) 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 than 1 part per million of boron is detrimental to citrus and other boron-sensitive 

crops. Boron is reported in Survey analyses of surface waters in 

arid and semiarid regions where irrigation is practiced or contemplated, but few of the surface waters analyzed have harmful concentrations of boron.
COMPOSITION OF SURFACE WATERS 13

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. Water 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, 

but generally water containing more than about 2, 000 ppm is considered to be unsuitable for long-term irrigation under average 

conditions.

PROPERTIES AND CHARACTERISTICS OF WATER

Water temperature

Large quantities of water are used in industrial operation; therefore temperature and seasonal fluctuations of that temperature are 

major considerations in planning the use of water for cooling in 

industrial plants. Water at high temperature can carry less oxygen 

in solution than at low temperature. Consequently water temperature can affect or determine the pollution characteristics of a 

stream. Temperature data are required in studies of water intended for aquatic life. A few degrees rise in temperature may 

seriously limit the capacity of a stream to support fish life.

Oxygen consumed

The amount of 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 sewage and 

oxidizable industrial wastes. Waters of naturally high color may 

have relatively high values for oxygen consumed, and 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
14 QUALITY OF SURFACE WATERS, 1956

that appear yellow, red, or brown when viewed in the stream show 

very little color after the suspended matter has been removed. 

The yellow-to-brown color of some waters is usually caused by 

organic matter extracted from leaves, roots, and other organic 

substances in the ground. In some areas objectionable color in 

water results from industrial wastes and sewage. Clear deep water 

may appear blue as the result of a scattering of sunlight by the 

water molecules. Water for domestic use and some industrial uses 

should be free from any perceptible color. A color less than 10 

units generally passes unnoticed. Some swamp waters have natural 

color of 200 to 300 units or more.

Hydrogen-ion concentration (pH)

The degree of acidity or alkalinity of water, as indicated by 

the hydrogen-ion concentration, expressed as pH (see p.7 ), 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 of 7.0 indicates that the 

water is neither acid nor alkaline. pH readings progressively lower 

than 7.0 denote increasing acidity and those progressively higher 

than 7.0 denote increasing alkalinity. 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 pH values less than 4.5.

Specific conductance (micromhos per centimeter at 25°C)

The specific conductance of a water is a measure of its capacity to conduct a current of electricity (see p.7 ). 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 indicating changes in concentration 

of the total quantity of dissolved minerals in surface waters.

Hardness

Hardness is the characteristic of water that receives the most 

attention in industrial and domestic use. It is commonly 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
COMPOSITION OF SURFACE WATERS 15

pipes, with the resultant decrease in rate of heat transfer, possibility of boiler failure, and loss of flow.

Hardness is caused almost entirely by compounds of calcium 

and magnesium. Other constituents--such as iron, manganese, 

aluminum, barium, strontium, and free acid also cause hardness, although they usually are not present in quantities large 

enough to have any appreciable effect. Water that has less than 

60 parts per million of hardness is usually rated as soft and suitable for many purposes without further softening. Waters with 

hardness ranging from 61 to 120 parts per million may be considered moderately hard, but this degree of hardness does not 

seriously interfere with the use of water for many purposes except for use in high-pressure steam boilers and in some industrial 

processes. Waters with hardness ranging from 121 to 200 parts 

per million are considered hard, and laundries and industries may 

profitably soften such supplies. Water with hardness above 200 

parts per million generally requires some softening before being 

used for most purposes.

Acidity

The acidity of a natural water represents the content of free 

carbon dioxide and other uncombined gases, organic acids, mineral acids and salts of strong acids and weak bases that hydrolyze 

to give hydrogen ions. Sulfate of iron and aluminum in mine and 

industrial wastes are common sources of acidity.

Corrosiveness

The corrosiveness of a water is that property which makes the 

water aggressive to metal surfaces and frequently results in the 

appearance of the "red-water" caused by solution of iron. The disadvantages of iron in water have been discussed previously. Additionally, 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 hotwater 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 containing appreciable 

quantities of carbonates and bicarbonates of calcium and magnesium.

Percent sodium

The proportion of sodium to the total cation concentration is 

termed "percent sodium", and is reported in most of the analyses
16 QUALITY OF SURFACE WATERS, 1956

of waters collected from streams in the western part of the country where irrigation is practiced extensively. The proportion of 

sodium to all the constituents in the water is explained on page 10 

under "Sodium and potassium*'. Waters in which the percent sodium is more than 60 may be injurious when applied to certain 

types of soils, particularly when adequate drainage is not provided 

(Magistad and Christiansen, 1944, p. 8-9).

Sodium-adsorption-ratio

Of more significance than percent sodium for use as an index 

of the sodium or alkali hazard to the soil is the sodium-adsorptionratio because it relates more directly to the adsorption of sodium 

by the soil. The term, "sodium-adsorption-ratio (SAR)" was introduced by the U. S. Salinity Laboratory Staff (1954), and is a 

ratio expressing the relative activity of sodium ions in exchange 

reactions with the soil. It is expressed by the equation:

SAR= Na+

\/ Ca+++Mg+:r' 

2

where the concentrations of the ions are expressed in milliequivalents per liter (or equivalents per million for most irrigation 

waters).

Waters are divided into four classes with respect to sodium 

or alkali hazard: low, medium, high, and very high, depending 

upon the SAR and the specific conductance. At a conductance of 

lOOmicromhos per centimeter the dividing points are at SAR values 

of 10, 18, and 26, but at 5,000 micromhos the corresponding dividing points are SAR values of approximately 2.5, 6.5, and 11. 

Waters range in respect to sodium hazard from those which can be 

used for irrigation on almost all soils to those which are generally unsatisfactory for irrigation.

SEDIMENT

Fluvial sediment is generally regarded as that sediment which 

is transported by, suspended in, or deposited by water. Suspended 

sediment is that part of it which remains in suspension in water 

owing to the upward components of turbulent currents or by colloidal suspension. Most fluvial sediment results from the normal 

process of erosion, which in turn is part of the geologic cycle of
STREAMFLOW 17

rock transformation. In some instances, this normal process may 

have been accelerated by agricultural practices. Sediment also 

results from a number of industrial activities. In certain sections, 

waste materials from mining, logging, oil-field, and other industrial operations introduce large quantities of suspended as well as 

dissolved material.

The quantity of sediment, transported or available for transportation, is affected by climatic conditions, form or nature of 

precipitation, plant cover, topography, and land use. An important property of fluvial sediment is the tall velocity of the particles in transport. Particle sizes, as determined by various methods, represent mechanical diameters, which are related to sedimentation diameters indirectly. Sediment particles in the sandsize (larger than 0.062 mm) range do not appear to be affected by 

flocculation or dispersion resulting from the mineral constituents 

in solution. The sedimentation diameter of clay and silt particles 

in suspension may very 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 velocity of 

water, turbulence, and the depth, width, and roughness of the channel. As a result of these variable characteristics, the size of 

particles transported, as well as the total sediment load, is in 

constant adjustment with the characteristics and physical features 

of the stream and drainage area.

STREAMFLOW

Most of the records of stream discharge, used in conjunction 

with the chemical analyses and in the computation of sediment loads 

in this volume, are published in Geological Survey reports on the 

surface-water supply of the United States. The discharge reported 

for a composite sample is usually the average of daily mean discharges for the composite period. The discharges reported in the 

tables of single analyses are either daily mean discharges or discharges for the time at which samples were collected, computed 

from a stage-discharge relation or from a discharge measurement.

RIO GRANDE BASIN Continued 

RIO GRANDE NEAR BERNARDO, N. HEX.

LOCATION. At gaging station at bridge on U. S. Highway 60, 2 miles east of Bernardo, 

Socorro County, and 3j miles upstream from Rio Puerco.

DRAINAGE AREA. 19,230 square miles, approximately (includes 2,940 square miles in closed 

basin in Northern part of San Luis Valley, Colo.).

RECORDS AVAILABLE. Sediment records: October 1947 to September 1956.

EXTREMES, 1955-56. Sediment loads: Maximum daily, 29,100 tons July 31; minimum daily, 

0 tons on many days.

EXTREMES, 1947-56. Sediment loads: Maximum daily, 348,000 tons Sept. 26, 1955; minimum 

daily, 0 tons on many days.

REMARKS. Records of specific conductance of daily samples and daily mean sediment concentrations for separate channels available in district office at Albuquerque, N. Mex. 

Records are summation of water and sediment discharges in main channel, conveyance channel, 

and Bernardo interior drain. Table for particle-size analyses for conveyance channel is 

published separately and shows water discharges and concentrations in that channel at the 

time of sampling. Daily sediment concentrations not listed because a composite concentration of more than one channel is meaningless. Records of discharge for water year October 

1955 to September 1956 given in WSP 1442.

PECOS RIVER SEEPAGE INVESTIGATION

Several series of water samples were collected during the months of January, February, and 

June 1956 on the Pecos River and its tributaries beginning at the gaging station near Acme, 

N. Hex., and ending at the gaging station near Artesia, N. Hex. Two double series of water 

samples were collected Jan. 4, 5 and Feb. 26, 27, respectively, and a single series was collected June 3, 1956. Samples were collected for chemical analysis at the time of discharge 

measurement. Discharge data are given in WSP 1442.
