QUALITY OF SURFACE WATERS 

OF THE UNITED STATES, 1958

PARTS 9-14 

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 State 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 sar 3 for which data are given in this volume were collected fron. October 1, 1957, to September 30, 1958. 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.

A station number has been assigned as an added means of identification for each stream location where regular measurements 

of water quantity or quality have been made. The numbers have 

been assigned to conform with the standard downstream order of 

listing gaging stations. The numbering system consists of two 

digits followed by a hyphen and a six digit number. The notation 

to the left of the hyphen identifies the Part or hydrologic region 

used by the Geological Survey for reporting hydrologic data. The 

number to the right of the hyphen represents the position of the 

location in the standard downstream order listing measuring stations within each of the 14 parts. The assigned numbers are in 

numerical order but are not consecutive. They are so selected 

from the complete 6 digit number scale that intervening numbers 

will be available for future assignments to new locations. The 

identification number for each station in this report is printed to 

the left of the station name and contains only the essential digits. 

For example, the number is printed as 4-100 for a station whose 

complete identification number is 04-0100. 00.
COLLECTION AND EXAMINATION OF SAMPLES

Descriptive statements are given for each sampling station 

for which regular series of chemical analyses, temperature, measurements, or sediment determinations have been made. These 

statements include the location of the station, drainage area, periods of records available, extremes of dissolved solids, hardness, specific conductance, temperature, sediment loads, and other 

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

sampling station are included in most tables of analyses.

During the water year ending September 30, 1958, the Geological Survey maintained 234 stations on 149 streams for the 

study of chemical and physical characteristics of surface water. 

Samples were collected daily or monthly at 157 of these locations 

for chemical-quality studies. Samples were also collected less 

frequently at many other points. Water temperatures were measured daily at 138 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, 

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 headings this information is available for reference at the district offices listed 

under Division of Work, on page 20.

Quantities of suspended sediment are reported for 40 stations 

during the year ending September 30, 1958. Sediment samples 

were collected one or more times daily during periods of significant flow at most of the continuous-record stations. Particle-size 

distributions of sediments were determined for 37 of the stations.

COLLECTION AND EXAMINATION OF SAMPLES

Samples for analyses are usually collected at or near points 

on streams where gaging stations are maintained by Surface Water 

Branch of U. S. Geological Survey for measurement of water discharge. The concentration of solutes and sediments at different 

locations in the stream-cross section may vary widely with different rates of water discharge depending on the source of the material and the turbulence and mixing of the stream. In general, the 

distribution of sediment in a stream section is much more variable 

than the distribution of solutes. It is necessary to sample some 

streams at several verticals across the channel and especially for 

sediment, to uniformly traverse the depth of flow. These measurements require special sampling equipment to adequately integrate the vertical and lateral variability of the concentration in the 

section. These procedures yield a velocity-weighted mean con719-305 O - 64 - 2

centration for the section in contrast to the average spatial concentration that existed without regard to the variable velocities of 

the individual fluid elements.

The nearly uniform dispersed ions of the solute move with the 

velocity of the transporting media. The mean section concentration of solutes determined from samples is a precise measure of 

the solute. The mean section concentration obtained from suspended-sediment samples is a less precise measure of the total 

sediment load, because sediment samplers did not traverse the 

bottom 0.4 foot of the sampling vertical where the concentration 

of suspended sediment is greatest and because a significant part 

of the coarser particles in many streams move in essentially continuous contact with the bed and are not represented in the suspended sediment sample. Hence, the suspended sediment loads 

presented in this report are usually less than the total sediment 

loads. For most streams the difference between the suspended 

and total sediment loads will be small, in the order of a few 

percent.

CHEMICAL QUALITY

The methods of collecting and compositing water samples for 

chemical analysis are described in a manual by Rainwater and 

Thatcher (1960, 301 p.). No single method of compositing samples is applicable to all problems related to the study of water 

quality. Although generally holding to the principle of 10 day periods or equivalent to three composite samples per month modifications are usually made on the basis of dissolved-solids content 

as indicated by measurements of conductivity of daily samples , 

supplemented by other information such as chloride content, river 

stage, weather conditions and other background information of the 

stream.

TEMPERATURE

Daily water temperatures were measured at most of the stations at the time samples were collected for chemical quality or 

sediment content. 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.
COLLECTION AND EXAMINATION OF SAMPLES 5

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 at two or more verticals to define more accurately the average concentration of the 

cross section. During periods of high or rapidly changing flow, 

samples were taken two or more times throughout the day at most 

sampling stations.

Sediment concentrations were determined by filtration-evapororation method. At many stations the daily mean concentration 

for some days was obtained by plotting the velocity-weighted instantaneous concentrations on the gage-height chart. The plotted 

concentrations, adjusted, if necessary for cross-sectional distribution were connected or averaged by continuous curves to obtain 

a concentration graph. This graph represented the estimated velocity-weighted concentration at any time, and for most periods 

daily mean concentrations were determined from the graph. The 

days were divided into shorter intervals when the concentration 

and water discharge were changing rapidly. During some periods 

of minor variation in concentration, the average concentration of 

the samples was used as the daily mean concentration. During 

extended periods of relatively uniform concentration and flow, 

samples for a number of days were composited to obtain average 

concentrations and average daily loads for each period.

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
6 QUALITY OF SURFACE WATERS, 1958

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 total sin order 

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.

The size of particles in stream sediments commonly range 

from colloidal clay (finer than 0.001 mm) to coarse sand or gravel 

(coarser than 1. 0 mm). The common methods of particle-size 

analyses cannot accomodate such a wide range in particle size. 

Hence, it was necessary to separate most samples into two parts , 

one coarser than 0. 062 mm and one finer than 0. 062 mm. The 

separations were made by sieve or by a tube containing a settling 

medium of water. The coarse fractions were classified by sieve 

separation or by the visual accumulation tube (U. S. Interagency, 

1957). The fine fractions were classified by the pipet method 

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

(U.S. Interagency, 1943, p. 82-90).

EXPRESSION OF RESULTS

Quantities of water for analysis are most conveniently obtained 

in the laboratory by use of volumetric glassware. The analytical 

results thus obtained are expressed in weights of solute in a given 

volume of water. To express the results in parts of solute per 

million (ppm) of water the data must be converted. For most waters 

this conversion is made by assuming that the liter of water sample 

weighs 1 kilogram; and thus milligrams per liter are equivalent 

to parts per million.

Chemical equivalence in equivalents per million (epm) can be 

obtained by (a) dividing the concentration in parts per million by 

the combining weight of that ion, or (b) multiplying the concentration (in ppm) by the reciprocal of the combining weights. The 

following table lists the reciprocals of the combining weights of 

cations and anions generally reported in water analyses.

The terms "equivalents per million" is a contraction which 

has been generally adopted for convenience. In more exact language, these units are "milligram equivalents per kilogram" if 

derived from part-per million data, or "milligram equivalents per
EXPRESSION OF RESULTS 7

liter" if derived from data expressed in milligrams per liter. 

Equivalent weights may be computed for use with any of the systems 

of expression of data (Hem, 1959, p. 30-34).

In an analysis expressed in equivalents per million, unit concentrations of all ions are chemically equivalent.

Results given in parts per million can be converted to grains 

per United States gallon by dividing by 17.12.

The hardness of water is conventionally expressed in all water analyses in terms of an equivalent quantity of calcium carbonate. Such a procedure is required because hardness is caused 

by several different cations, present in variable proportions. It 

should be remembered that hardness is an expression in conventional terms of a property of water. The actual presence of calcium carbonate in the concentration given is not to be assumed. 

The hardness caused by calcium and magnesium (and other cations 

if significant) equivalent to the carbonate and bicarbonate is called 

carbonate hardness; the hardness in excess of this quantity is 

called noncarbonate hardness. Hardness or alkalinity values expressed in parts per million as calcium carbonate may be converted to equivalents per million by dividing by 50.

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
8 QUALITY OF SURFACE WATERS, 1958

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.

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 micromhos 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. 23 ) and the temperature in degrees 

Fahrenheit. Color is expressed in units of the platinum-cobalt 

scale proposed by Hazen (1892, p. 427-428). A unit of color is 

produced by one milligram per liter of platinum in the form of the 

chloroplatinate ion. 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 as 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 passing a given station 

during the year after thorough mixing in the reservoir. A dischargeweighted average is computed by multiplying the discharge for the 

sampling period by the concentrations of the individual constituents 

for the corresponding period and dividing the sum of the products 

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.
COMPOSITION OF SURFACE WATERS 9

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 mineral matter. 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 spring 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 dissolved-solids content in a river 

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 

calculated as sodium), alkalinity as carbonate and bicarbonate, 

sulfate, chloride, fluoride, nitrate, boron, pH, dissolved solids 

and specific conductance. Aluminum, manganese, color, acidity, 

oxygen consumed, and other dissolved constituents and physical 

properties are reported for certain streams. Phenolic 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. The constituents are arranged in .the order that they 

appear on standard analytical statement cards which are used to 

process the chemical quality data in this report.
10 QUALITY OF SURFACE WATERS, 1958

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 

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 maybe troublesome in feed waters where it tends 

to be deposited as a scale on boiler tubes.

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.

Manganese (Mn)

Manganese is dissolved in appreciable quantities from rocks 

in some sections of the country. It resembles iron in its chemical 

behavior and in its occurrence in natural waters. However, manganese in rocks is less abundant than iron. As a result the concentration of manganese is much less than that of iron and is not 

regularly determined in many areas. 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. It is especially objectionable in water used in laundry work and in textile
COMPOSITION OF SURFACE WATERS, 1958 11

processing. 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.

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-bearing rocks may contain from 20 to 100 

parts per million or more of magnesium.

Strontium (Sr)

Strontium is a typical alkaline-earth element and is similar 

chemically to calcium. Strontium may be present in natural water 

in amounts up to a few parts per million much more frequently 

than the available data indicate. In most surface water the amount 

of strontium is small in proportion to calcium. However, in sea 

water the ratio of strontium to calcium is 1:30.

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 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
12 QUALITY OF SURFACE WATERS, 1958

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.

In this report, the potassium values not shown are usually calculated in with the sodium and reported as sodium.

Lithium (Li)

Data concerning the quantity of lithium in water are scarce. 

It is usually found in small amounts in thermal springs and saline 

waters. Lithium also occurs in streams where some industries 

dump their waste water. The scarcity of lithium in rocks is responsible more than other factors for relatively small amounts 

present in water.

Bicarbonate, carbonate and hydroxide (HCO3 , CO3 , OH)

Bicarbonate, carbonate, or hydroxide is sometimes reported 

as alkalinity. The alkalinity of a water is defined as its capacity 

to consume a strong acid to pH 4. 5. Since the major causes of 

alkalinity in most natural waters are carbonate and bicarbonate 

ions dissolved from carbonate rocks, the results are usually reported in terms of these constituents. Although alkalinity may 

suggest the presence of definite amounts of carbonate, bicarbonate 

or hydroxide, it may not be true due to other ions that contribute 

to alkalinity such as silicates, phosphates, borates, possibly fluoride, and certain organic anions which may occur in colored waters. 

The significance of alkalinity to the domestic, agriculture, and 

industrial user is usually dependent upon the nature of the cations 

(Ca, Mg, Na, K) associated with it. However, moderate amounts 

of alkalinity does not adversely affect most users.

Hydroxide may occur in water that has been softened by the 

lime process. Its presence in streams usually can be taken as an 

indication of contamination and does not represent the natural 

chemical character of the water.

Sulfate (SO4 )

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
COMPOSITION OF SURFACE WATERS 13

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-in-flow 

carrying appreciable quantities of chloride. Large quantities of 

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 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, fluoride in excessive concentrations is undesirable in waters 

used for drinking. It is stated in a comprehensive report by the 

California State Water Pollution Control Board (1952, p. 257) on 

water-quality standards"... that water containing less than 0. 9 to 

1.0 ppm of fluoride will seldom cause mottled enamel in children, 

and for adults concentrations less than 3 or 4 ppm are not likely 

to cause endemic cumulative fluorosis and skeletal effects. "

Nitrate (NO3)

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 surf ace 

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 inter crystalline cracking 

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

excess of 70 parts per million (as NO3) may contribute to methe-
14 QUALITY OF SURFACE WATERS, 1958

moglobinemia ("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 ppm 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 NO3) should be regarded as unsafe for infant feeding.

Phosphate (PO4 )

Phosphorus is an essential element in the growth of plants and 

animals, and some sources that contribute nitrate, such as organic wastes and leaching of soils, may be important as sources 

for phosphate in water and its occurrence may add to the apparent 

alkalinity. The addition of phosphates in water treatment constitutes a possible source, although the dosage is usually small. In 

some areas, phosphate fertilizers may yield some phosphate to 

water. A more important source is the increasing use of phosphates in detergents. Domestic and industrial sewage effluents 

may therefore contain considerable amounts of phosphate.

Boron (B)

Boron in small quantities has been found essential for plant 

growth, but irrigation water containing more than 1 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.

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.
COMPOSITION OF SURFACE WATERS 15

Chromium (Cr)

Few if any waters contain chromium from natural sources. 

Natural waters can probably contain only traces of chromium as 

a cation unless the pH is very low. When chromium is present in 

water, it is usually the result of pollution by industrial wastes. 

Fairly high concentrations of chromate anions are possible in waters having normal pH levels. Concentrations of more than 0. 05 

ppm of Cr in the hexavalent form constitutes ground for rejection 

of a water for domestic use on the basis of the standards of the 

U.S. Public Health Service (1946).

Nickel and cobalt (Ni, Co)

Nickel and cobalt are very similar in chemical behavior and 

also closely related to iron. Both are present in igneous rocks in 

small amounts and are more prevalent in silicic rocks. Any nickel 

in water is likely to be in small amounts and could be in a colloidal 

state. Cobalt may be taken into solution more readily than nickel. 

It may be taken into solution in small amounts through bacteriological activity similar to that causing solution of manganese. 

However, few data on the occurrence of either nickel or cobalt in 

natural water are available.

Copper (Cu)

Copper is a fairly common trace constituent of natural water. 

Small amounts maybe introduced into water by solution of copper 

and brass water pipes and other copper-bear ing equipment in contact with the water, or from copper salts added to control algae 

in open reservoirs. Copper salts such as the sulfate and chloride 

are highly soluble in waters with a low pH but in water of normal 

alkalinity these salts hydrolyze and the copper may be precipitated. In the normal pH range of natural water containing carbon 

dioxide, the copper might be precipitated as carbonate. The oxidized portions of sulfide-copper ore bodies contain other copper 

compounds. The presence of copper in mine water is common.

Copper imparts a disagreeable metallic taste to water. As 

little as 1. 5 ppm can usually be detected, and 5 ppm can render 

the water unpalatable. Copper is not considered to be a cumulative systemic poison like lead and mercury; most copper ingested 

is excreted by the body and very little is retained. The pathological effects of copper are controversial, but it is generally believed very unlikely that humans could unknowingly ingest toxic 

quantities from palatable drinking water. The U.S. Public Health 

Service (1946) recommends that copper should not exceed 3. 0 ppm
16 QUALITY OF SURFACE WATERS, 1958

in drinking and culinary water on carriers subject to Federal quarantine regulations.

Lead (Pb)

Lead is only a minor element in most natural waters, but industrial or mine and smelter effluents may contain relatively large 

amounts of lead. Many of the commonly used lead salts are water 

soluble.

Traces of lead in water usually are the result of solution of 

lead pipe through which the water has passed. Amounts of lead of 

the order of 0.1 ppm are significant, as this concentration is the 

upper limit for drinking water in the standards adopted by the 

U. S. Public Health Service (1946). Higher concentrations may be 

added to water through industrial and mine-waste disposal. Lead 

in the form of sulfate is reported to be soluble in water to the extent of 31 ppm (Seidell, 1940, p. 1409) at 25°C. In natural water 

this concentration would not be approached, however, since a pH 

of less than 4. 5 would probably be required to prevent formation 

of lead hydroxide and carbonate. It is reported (Pleissner, 1907) 

that at 18°C water free of carbon dioxide will dissolve the equivalent of 1.4 ppm of lead and the solubility is increased nearly 

four fold by the presence of 2. 8 ppm of carbon dioxide in the solution. Presence of other ions may increase the solubility of lead.

Zinc (Zn)

Zinc is abundant in rocks and ores but is only a minor constituent in natural water because the free metal and its oxides are 

only sparingly soluble. In most alkaline surface waters it is present only in trace quantities, but more maybe present in acid water. 

Chlorides and sulfates of zinc are highly soluble. Zinc is used in 

many commercial products, and industrial wastes may contain 

large amounts.

Zinc in moderate concentrations is not known to have adverse 

physiological effects on man or stock, but zinc salts give water an 

unpleasant astringent taste and form a greasy film on boiling water 

(Howard, 1923, p. 411). The U. S. Public Health Service (1946, 

p. 13) recommends that the zinc content not exceed 15 ppm in 

drinking and culinary water on carriers subject to Federal quarantine regulations.

Barium (Ba)

Barium may replace potassium in some of the igneous rock
COMPOSITION OF SURFACE WATERS 17

minerals, especially feldspar and barium sulfate (barite) fs a common barium mineral of secondary origin. Only traces of barium 

are present in surface water and sea water. Because natural water contains sulfate, barium will dissolve only in trace amounts. 

Barium sometimes occurs in brines from oil-well wastes.

The U. S. Public Health Service (1946) states that salts of barium, which have a deleterious physiological effect, must not be 

added to drinking and culinary water on carriers subject to Federal quarantine regulations.

Bromide (Br)

Bromine is a very minor element in the earth's crust and is 

normally present in surface waters in only minute quantities. 

Measurable amounts may be found in some streams that receive 

industrial wastes, and some natural brines may contain rather high 

concentrations. Probably trace amounts of bromide are of frequent occurrence in surface water since compounds containing 

bromine are generally readily soluble. It resembles chloride in 

that it tends to be concentrated in sea water.

Iodide (I)

Iodine, like bromine, is a minor element and is normally present in natural waters in only minute quantities. Measurable amounts may be found in some streams that receive industrial 

wastes, and some natural brines may contain rather high concentrations. It occurs in sea water to the extent of less than 1 ppm. 

Rankama and Sahama (1950, p. 767) report iodide present in rainwater to the extent of 0. 001 to 0. 003 ppm and in river water in 

about the same amount. Few waters will be found to contain over 

2. 0 ppm.

PROPERTIES AND CHARACTERISTICS OF WATER 

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 pipes, with the resultant decrease in rate of heat transfer,
18 QUALITY OF-SURFACE WATERS, 1958

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 required some softening before being 

used for most purposes.

Acidity (H+1 )

The use of the terms acidity and alkalinity is widespread in 

the literature of water analysis and is a cause of confusion to those 

who are more accustomed to seeing a pH of 7. 0 used as a neutral 

point. Acidity of a natural water represents the content of free 

carbon dioxide and other uncombined gases, organic acids and 

salts of strong acid's and weak bases that hydrolyze to give hydrogen ions. Sulfates of iron and aluminum in mine and industrial 

wastes are common sources of acidity. The presence of acidity 

is reported in those waters which have a pH below 4. 5.

Sodium-adsorption-ratio (SAR)

The term "sodium-adsorption-ratio (SAR)" was introduced by 

the U. S. Salinity Laboratory Staff (1954). It is a ratio expressing 

the relative activity of sodium ions in exchange reaction with soil 

and is an index of the sodium or alkali hazard to the soil. Sodiumadsorption-ratio is expressed by the equation:

SAR= Ca+++MgH

where the concentrations of the ions are expressed in milliequiv-
COMPOSITION OF SURFACE WATERS 19

alents 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 100 mi - 

cromhos per centimeter the dividing points are at SAR values of 

19, 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.

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. 8 ). 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.

Specific conductance of most waters in the Eastern United 

States is less than 1,000 micromhos, but in the arid western parts 

of the country, a specific conductance of more than 1,000 micromhos is common.

Hydrogen-ion concentration (pH)

Hydrogen-ion concentration is expressed in terms of pH units 

(see p. 8 ). The values of pH often are used as a measure of the 

solvent power of water or as an indicator of the chemical behavior 

certain solutions may have toward rock minerals.

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 watertreatment 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 

or organic matter usually have pH values less than 4. 5.

The investigator who utilizes pH data in his interpretations of 

water analyses should be careful to place pH values in their proper 

perspective.

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

organic matter extracted from leaves, roots, and other organic 

substances in^he 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.

The extent to which a water is colored by material in solution 

is commonly reported as a part of a water analysis because a significant color in water may indicate the presence of organic material that may have some bearing on the dissolved solids content. 

Color in water is expressed in terms of units between 0 and 500 

or more based on the Hazen's arbitrary standard (see p. 8).

Oxygen consumed

Oxygen consumed is a measure of the amount of oxygen required to oxidize unstable materials in water and may be cor related with natural-water color or with some carbonaceous organic 

pollution from sewage or industrial wastes.

Tolerances for oxygen consumed in feed water for low- and 

high-pressure boilers are 15 and 3 ppm, respectively (Northeast 

Water Works Association, 1940). Wash water containing more 

than 8 ppm has been reported to impart a bad odor to textiles; 

concentrations for water used in beverages and brewing range from 

0. 5 to 5. 0 ppm (California State Water Pollution Control Board, 

1952, 1954).

Organics

Phenols. Phenolic material in water resources is invariably 

the result of pollution. Phenols are widely used as disinfectants 

and in the synthesis of many organic compounds. Waste products 

from oil refineries, coke areas, and chemical plants may contain 

high concentrations. Fortunately, phenols decompose in the pres-
COMPOSITION OF SURFACE WATERS 21

ence of oxygen and organic material, and their persistence downstream from point of entry is relatively short lived. The rate of 

decomposition is dependent on the environment.

Very low concentrations impart such a disagreeable taste to 

water that it is highly improbable that harmful amounts could be 

consumed unknowingly. Reported thresholds of detection of taste 

and odor range from 0.01 to 0.1 ppm.

Detergents (ABS). The major type of detergents is the alkylbenzene-sulfonate group, which are highly resistant to biological 

degradation so that the effect of ABS in water persists over a long 

period of time. Waste water may carry these detergents to surface water supplies with resulting deterioration of water quality 

which includes unpleasant taste, odor, and foaming. Very little 

is known concerning the nature and the extent of occurrence and 

movement of detergents in waters or of the chemical and physical 

change that they may undergo after being added to surf ace waters 

(U.S. Geological Survey-Federal Housing, 1959).

Temperature

Temperature is an important factor in property determining 

the quality of water. This is very evident for such a direct use 

as an industrial coolant. Temperature is also important, but perhaps not so evident, for its indirect influence upon aquatic biota, 

concentrations of dissolved gases, and distribution of chemical 

solutes in lakes and reservoirs as a consequence of thermal stratification and variation.

Surf ace water temperatures tend to change seasonally and daily 

with air temperatures, except for the outflow of large springs. 

Superimposed upon the annual temperature cycle is a daily fluctuation of temperature which is greater in warm seasons than in 

cold and greater in sunny periods than with a cloud cover. Natural warming is due mainly to absorption of a solar radiation by 

the water and secondarily to transfer of heat from the air or from 

the bottom. Condensation of water vapor at the water surface is 

reported to furnish measurable quantities of heat. Heat loss takes 

place largely through radiation, with further losses through evaporation and conduction to the air and bottom. Thus the temperature of a small stream generally reaches a maximum in mid-to 

late afternoon due to solar heating and reaches a minimum from 

early to mid-morning after nocturnal radiation.

Temperature variations which commonly occur during summer in lakes and reservoirs of temperate regions results in a 

separation of the water volume into a circulating upper portion 

and a non-circulating lower portion. Separating the two is a stratum of water of variable vertical thickness in which the temperature
22 QUALITY OF SURFACE WATERS, 1958

decreases rapidly with increasing depth. This physical division 

of the water mass into a circulating and a stagnant portion is the 

result of density differences in the water column associated with 

the temperature distribution. Knowledge of the stratification in a 

body of water may result in increased utility by locating strata of 

more suitable characteristics. For example, the elevation of an 

intake pipe may be changed to obtain water of lower temperature, 

higher pH, less dissolved iron, or other desirable properties. 

Temperature is a major factor in determining the effect of 

pollution on aquatic organisms. The resistance of fish to certain 

toxin substances has been shown to vary widely with temperature. 

The quantity of dissolved oxygen which the water can contain is 

also temperature dependent. Oxygen is more soluble in cold water than in warm water, hence the reduction of oxygen concentrations by pollution is especially serious during periods of high 

temperature when oxygen levels are already low. Increased temperatures also accelerate biological activity including that of the 

oxygen-utilizing bacteria which decompose organic wastes. These 

pollutional effects may be especially serious when low flow conditions coincide with high temperatures. Summary temperature 

data of water are essential for planning multiple uses of water 

resources.

Turbidity

Turbidity is the optical property of a suspension with reference to the extent to which the penetration of light is inhibited by 

the presence of insoluble material. Turbidity is a function on both 

the concentration and particle size of the suspended material. 

Although it is reported in terms of parts per million of silica, it 

is only partly synonymous with the weight of sediment per unit 

volume of water.

Turbid water is abrasive in pipes, pumps, and turbine blades. 

In process water, turbidities much more than 1 ppm are not tolerated by several industries, but others permit up to 50 ppm 

higher (Rainwater, Thatcher, 1960, p. 289).

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. Much fluvial sediment results from the natural 

process of erosion, which in turn is part of the geologic cycle of
STREAMFLOV 23

rock transformation. This natural process may be accelerated 

by agricultural practices. Sediment is also contributed by a number of industrial and construction 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, character of the soil mantle, plant cover, topography, and land use. The mode and rate of sediment erosion, 

transport, and deposition is determined largely by the size distribution of the particles or more precisely by the fall velocities of 

the particles in water. Sediment particles inthe'sandsize (larger 

than 0. 062 mm) range do not appear to be affected by flocculation 

or dispersion resulting from the mineral constituents in solution. 

In contrast, 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 W 

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.

COOPERATION

Assistance in collecting records for chemical-quality and 

sediment investigations was given by many municipal, State, and 

Federal agencies. The Bureau of Reclamation of the Unites States 

Department of the Interior furnished financial assistance for the 

operation of some stations in Arizona and Utah. Chemical-quality 

investigations in the Great Basin and Pacific slope basins in California and upper Virgin River basin in Utah and Arizona were continued in cooperation with the States of California and Utah. Investigations of sediment characteristics of the Green River near 

Palmer, Wash., were continued in cooperation with the city of
26 QUALITY OF SURFACE WATERS, 1958

Tacoma. Sediment investigations of the San Juan River at Bloomfield, N. Mex., and chemical-quality investigations of the San Juan 

River at Shiprock, N. Mex., were continued in cooperation with 

the State of New Mexico. The Soil Conservation Service of the 

United States Department of Agriculture assisted on special sediment studies in the Gila River basin in Arizona.

In addition to the cooperative program, many of the stations 

were operated from funds appropriated directly to the Geological 

Survey for quality-of-water investigations. Investigations of the 

chemical quality and suspended-sediment loads in the Colorado 

River basin in Arizona, Colorado, Nevada, New Mexico, and Utah 

have been carried on as a continuing Federal project since 1925.
