QUALITY OF SURFACE WATERS 

OF THE UNITED STATES, 1952

PARTS 1-4 

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.

The regular yearly publication of records of chemical analyses, 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. 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 were 

collected from October 1, 1951, to September 30, 1952. Descriptive 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, hardness, 

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 basins, according to Geological Survey practice in reporting records of stream 

flow.

Figure 1. Map of the United States showing basins covered 

by the four water-supply papers on quality of surface waters 

in 1952. The shaded portion represents the section of the 

country covered by this volume; the unshaded portion represents the section of the country covered by other watersupply papers.

Beginning with the series of reports for the water year ending 

September 30,1951, the order of listing station records has been 

changed. In this report, stations on tributary streams are listed 

between stations on the main stream in the order in which those 

tributaries enter the main stem. Stations on tributaries to tributaries are inserted in a similar manner.

During the year ended September 30, 1952, 99 regular sampling stations on 77 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 77 of the regular sampling stations. Not all analyses of samples of surface water collected 

during the year have been included. Single analyses of an incomplete nature generally have been omitted. Also, determinations 

made on the daily samples before compositing have not been reported. 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 offices listed under Division of Work, on pages 17-18.

Quantities of suspended sediment are reported for 25 stations during the year ended September 30, 1952. 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
COLLECTION AND EXAMINATION OF SAMPLES 3

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. As noted under "Remarks" in 

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 filtration plants utilizing these stream waters. Records of these infrequent 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 termed suspended sediment and generally constitutes the major part 

of the total sediment load. At the present time no reliable method 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 maintained for measurement of water discharge. Most of the analyses 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 composited for shorter periods on the basis of the concentration of 

dissolved solids indicated by measurements of specific conductance of the daily samples.

The samples were analyzed according to methods regularly 

used by the Geological Survey. These methods 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., 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 analyses the value reported as dissolved solids is the residue on evaporation after drying at 180°C for 1 hour. Specific conductance 

is givenfor most analyses and was determined by means of a conductance bridge using a standard potassium chloride solution as 

reference.
QUALITY OF SURFACE WATERS, 1952

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 tothat at 

the daily sampling vertical. In streams where comparatively rapid 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 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 mean 

daily 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 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 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 sediment 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 sediment loads were estimated on the basis of water discharge, sediment concentrations observed immediately preceding and following the periods, and 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 sediment loads for individual days are not estimated, as numerous factors influencing the quantities of transported 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, records of the particle sizes of sediment are included also. The 

particle sizes of the suspended sediments were determined periodically for many of the stations. As much of the material carried in suspension can pass through the finest sieves, the bottomwithdrawal 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 analyzed 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 often affected by the chemical character of the settling medium, analyses made using native water may more nearly simulate particle sizes existing in the 

stream. Results of analyses using distilled water or using a settling medium containing dispersing agents 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 pipette method. The concentration of suspended 

sediment used in the bottom-withdrawal tube or pipette cylinder 

was often different from the concentration in the original suspension. The concentration at which analyses were made is indicated in the appropriate tables.

TEMPERATURE

For most of the stations, daily water temperatures were obtained 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 unaffected by diurnal variations in temperature. For most large, swiftly flowing streams the diurnal variation in water temperature 

is probably small, but for sluggish or shallow streams the daily 

range in temperature may amount to several degrees 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 the thermograph observations consist of maximum 

and minimum temperatures for each day, and the monthly averages of the maximum daily and 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^port 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 and is calculated by dividing the 

concentration in parts per million by the chemical combining 

weight of the constituent. 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 (CO3~) .. 0. 0333

Iron (Fe+++) ......... . 0537 Bicarbonate (HCO3 -) . 0164

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

Magnesium (Mg++) .... 0822 Chloride (C1-)...... . 0282

Sodium (Na+) ........ . 0435 Fluoride-JF") ...... . 0526

Potassium (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 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, as calcium carbonate (CaCO3 ), is calculated 

from the equivalents of calcium and magnesium except for a few 

samples for which the reported values also include equivalents 

of free mineral acid, aluminum, iron, and manganese when present in significant quantities. The hardness caused by calcium 

and magnesium (and other ions if significant) equivalent to the 

carbonate and bicarbonate is called carbonate hardness; the hardness in excess of this quantity is called noricarbonate hardness.

In the analyses of most waters used for irrigation, the quantity of dissolved solids is given in tons per acre-foot as well as 

in parts per million. Percent sodium has been computed for those 

analyses where sodium and potassium are reported separately 

by dividing the 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 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 

times 106 (micromhos at 25°C). The discharge of the streams is 

reported in cubic feet per second (See Stream Flow, p. 19) and the 

temperature in degrees Fahrenheit. Color is expressed in units of 

the platinum-colbalt 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 water year is given for most daily sampling stations. An arithmetical 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 mixing 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 corresponding period and dividing the sum of the products by the sum 

of the discharges. Water as represented by the weighted average is less concentrated than that represented by the average of 

the individual analyses for most streams be cause at times of high 

discharge the rivers generally have lower concentrations of dissolved solids.

Mean daily sediment concentrations are expressed in parts per 

million by weight. A part per million of sediment 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 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 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 through which the water has passed and the length
8 QUALITY OF SURFACE WATERS, 1952

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 character of their concentrated underground sources during dry periods and are more dilute during periods of heavy rainfall. Underground 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 irrigated regions by return drain waters.

The mineral constituents and physical properties of natural 

waters reported in the tables of analyses include those that have 

a practical bearing on the value of the waters for most purposes. 

The analyses generally include results for silica, iron, calcium, 

magnesium, sodium, potassium (or sodium and potassium together as so'dium), bicarbonate, sulfate, chloride, fluoride, nitrate, boron, and dissolved solids. Aluminum, manganese, color, pH, acidity, oxygen consumed, and other dissolved constituents and physical properties are reported for certain streams. 

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

MINERAL CONSTITUENTS IN SOLUTION

Silica (Si02)

Silica is dissolved from practically all rocks. Some natural 

surface waters contain less than 5 parts per million of silica 

and 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 waters 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 reservoirs may contain manganese that has been dissolved from the 

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

produced by anaerobic fermentation of organic matter. Manganese is not regularly determined in areas where it is not present 

in the waters in appreciable amounts. It is especially objectionable in water used in laundry work and in textile processing. 

Concentrations as low as 0. 2 part per million may cause a darkbrown or black stain on fabrics and porcelain fixtures. Appreciable quantities of manganese are often found in waters containing objectionable quantities of iron.

Iron (Fe)

Iron is dissolved from many rocks and soils. On exposure 

to the air, normal basic waters that contain more than 1 part per 

million of iron soon become turbid with the insoluble reddish ferric oxide produced by oxidation. Surface waters, therefore, seldom contain as much as 1 part per million of dissolved iron, 

although some acid waters carry large quantities of iron in solution. Iron 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. 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.
10 QUALITY OF SURFACE WATERS, 1952

Sodium and potassium (Na and K)

Sodium and potassium are dissolved from practically all rocks. 

Sodium is the predominant cation in some of the more highly mineralized waters found in the western Untied States. Natural waters that contain only 3 or 4 parts per million of the two together 

are likely to carry almost as much potassium as sodium. As the 

total quantity of these constituents increases, the proportion of 

sodium becomes much greater. Moderate quantities of sodium 

and potassium have little effect on the usefulness of the water for 

most purposes, but waters that carry more than 50 or 100 parts 

per million of the two may require careful operation of steam 

boilers to prevent foaming. More highly mineralized waters that 

contain a large proportion of sodium salts may be unsatisfactory 

for irrigation.

Carbonate and bicarbonate (C03 and HC08)

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.

Sulf ate (S04)

Sulfate is dissolved from many rocks and soils 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, 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 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 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,)

Nitrate in water is considered a final oxidation product of nitrogenous material and in some instances may indicate previous 

contamination by sewage or other organic matter. The quantities 

of nitrate present in surface waters usually amount to 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 be the cause of methemoglobinemia 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 million 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, 1952

Dissolved solids

The reported quantity of dissolved solids the residue on evaporation--consists mainly of the dissolved mineral constituents 

in the water. It may also contain some organic matter and water of crystallization. Waters with less than 500 parts per million of dissolved solids are usually satisfactory for domestic and 

some industrial uses. Waters containing several 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 sewage and oxidizable industrial wastes. Naturally highly colored 

waters may have relatively high oxygen consumed, although waters that are not noticeably colored may contain oxidizable material.

Color

In water analysis the term "color" refers to the appearance 

of water that is free from suspended solids. Many turbid waters 

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

show very little color after the suspended matter has been removed. The ye How-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 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 water is neither acid nor alkaline. Waters having pH values progressively lower than 7. 0 denote increasing acidity, whereas 

values progressively higher than 7.0 denote increasing alkalinity.
COMPOSITION OF SURFACE WATERS 13

(See p. 7 ). 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 at 25 C)

The specific conductance of a water is a measure of its capacity to conduct a current of electricity. The conductance 

varies with the concentration and degree of ionization of the different minerals in solution and with the temperature of the water. 

When considered in conjunction with results of determinations 

for other constituents, specific conductance is a useful determination and plays an important part in indicating changes in 

concentration of the total quantity of dissolved minerals in surface 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, 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 usually requires some softening 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 salts--especially sulfates 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, 1952

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 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 containing appreciable quantities of carbonates and bicarbonajtes 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 suitability of a water for irrigation. (See p. 6 .) 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; 

Wilcox, 1948, p. 6).

SEDIMENT

Fluvial sediment is generally regarded as that sediment which 

is transported by, suspended in, or deposited by water. Suspended 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 geologic cycle of 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, vegetal cover, topography, and land use. An important 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 (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 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 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.

PUBLICATIONS

Reports 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, 1949, 1950, and 1951, for many of the stations

logical Survey for quality-of-water investigations.

Assistance in collecting records was given by many municipal, 

State, and Federal agencies.

DIVISION OF WORK

The quality-of-water program was conducted by the Water Resources 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 publication 

under the supervision of district chemists as follows: In Florida, 

Eugene Brown; in North Carolina and South Carolina, G. A. Billingsley; in Virginia, M. E.»Schroeder; in Ohio, W. L. Lamar; 

in Delaware and Pennsylvania, N. H. Beamer; and in New York, 

F. H. Pauszek. Any additional analytical data on file can be obtained by writing the responsible Survey 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, are published in Geological Survey reports 

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

reported for a composite sample is usually the average of the 

mean daily discharges for the normal composite period. For 

analyses 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 discharges 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.
