QUALITY OF SURFACE WATERS 

OF THE UNITED STATES, 1960

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 

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 all 

uses. 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 

maybe expected during the periods of high flow than during periods 

of low flow. The concentration in some streams may change materially with relatively small variations in flow, whereas for other 

streams the quality may remain relatively uniform throughout large 

ranges in discharge. The quantities of suspended sediment carried 

by streams are also related to discharge, and during floodperiods 

the sediment content in streams may vary over wide ranges.

In 1941, the Geological Survey began publishing annual records of chemical quality, suspended sediment, and water temperature. The records prior to 1948 were published each year in a 

single volume for the entire country, and in two volumes in 1948 

and 1949. Beginning in 1950, the records were published in four 

volumes and beginning in 1959 in five volumes. The drainage basins covered in the five volumes are shown in Figure 1. The data 

given in this volume were collected during the water year October 1, 1959, to September 30, 1960. The records are arranged 

by drainage basins in downstream order according to the Geological Survey method of reporting streamflow. Stations on tributary 

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

in which those tributaries enter the main stem.

quality of surface waters in 1960. 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 water-supply papers.

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 3

Descriptive statements are given for each sampling station 

where 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, 1960, the Geological Survey maintained 368 stations on 250 streams for the study 

of chemical and physical characteristics of surface water. Samples were collected daily and monthly at 278 of these locations for 

chemical-quality studies. Samples were also collected less frequently at many other points. Water temperatures were measured 

daily at 163 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 26.

Quantities of suspended sediment are reported for 40 stations 

during the year ending September 30, 1960 . Sediment samples 

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

on the rate of flow and changes in stage of the stream. Particlesize distributions of sediments were determined at 15 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 con-
4 QUALITY OF SURFACE WATERS, 1960

centration for the section in contrast to the average concentration 

that existed without regard to the variable velocities of the individual fluid elements.

The near uniformly dispersed ions of the solute load move 

with the velocity of the transporting water. Accordingly, the mean 

section concentration of solutes determined from samples is a 

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

precise measure of the total sediment load, because the sediment 

samplers do not traverse the bottom 0.3 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 computed sediment loads presented in this report are usually 

less than the total sediment loads. For most streams the difference between the computed 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, 1963, p. 56-77 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-evaporation 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 folio wing 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, I960

not estimated, because numerous factors influencing the quantities 

of transported sediment made it very difficult to make accurate 

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

of sampling have been included in monthly and annual totals in 

order to provide a complete record. For some streams, samples 

were collected 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 sediment 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 accommodate 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 measured in the laboratory by use of volumetric glassware. The analytical results thus obtained in this report 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 equal to parts per million.

Equivalents per million are not reported, although the expression of analyses in equivalents per million is sometimes preferred. An equivalent per million (epm) is a unit chemical combining .weight of a constituent in a million unit weights of water. 

Chemical equivalence in equivalents per million 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.

Chemistry, 1961).

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 bv 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, 1960

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. 24 ) 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, 

time-weighted, or discharge-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 aver age 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 discharge-weighted average is computed by multiplying the discharge for the sampling period by the 

concentrations of 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.

A program for computing these averages on an electronic 

digital computer was instituted in the 1962 water year. This program extended computations to include averages for pH values 

expressed in terms of hydrogen ion and averages for the concentration of individual constituents expressed in tons per day. Concentrations in tons per day are computed the same as daily sediment loads.
COMPOSITION OF SURFACE WATERS 9

The concentration of sediment in parts per million is computed as 1,000,000 times the ratio of the weight of sediment to the 

weight of water-sediment mixture. Daily sediment loads are expressed in tons per day and except for subdivided days are usually 

obtained by multiplying daily mean sediment concentration in parts 

per million by the daily mean discharge, and the appropriate conversion factor, normally 0. 0027.

Particle-size analyses are expressed in percentages of material finer than indicated sizes in millimeters. The size classification used in this report is that recommended by the American 

Geophysical Union subcommittee on Terminology (Lane and others, 

1947, p. 937). Other data included as pertinent to the size analyses for many streams are the date of collection, the stream discharge, sediment concentration when sample was collected, 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
10 QUALITY OF SURFACE WATERS, I960

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.

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 of ten 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
COMPOSITION OF SURFACE WATERS 11

behavior and in its occurrence in natural waters. However, manganese in rocks is less 1 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 

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 

s.iliciQus 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 surf ace water the amount 

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

water the i*atio of strontium to calcium is 1:30.
12 QUALITY OF SURFACE WATERS, 1960 

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 

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.

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, agricultural, 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.
COMPOSITION OF SURFACE WATERS 13

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 

inconsiderable 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 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. Investigations have proved that fluoride concentrations of about 0. 6 to 1.7 ppm reduced the incidence of dental caries and that concentrations greater than 1. 7 ppm also protect the teeth from cavities but cause an undesirable black stain 

(Durfor and Becker, 1964, p. 20). Public Health Service, 1962 

(p. 8), states, "When fluoride is naturally present in drinking 

water, the concentration should not average more than the appropriate upper control limit (0.6 to 1.7 ppm). Presence of fluoride 

in average concentration greater than two times the optimum values shall constitute grounds for rejection of the supply." Concentration higher than the stated limits may cause mottled enamel in 

teeth, 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
14 QUALITY OF SURFACE WATERS, I960

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 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 ppm (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. U. S. 

Public Health Service (1962) sets 45 ppm as the upper limit.

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 50Q parts per million of
COMPOSITION OF SURFACE WATERS 15

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.

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 chromium in the hexavalent form constitute grounds for 

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

of the U. S. Public Health Service (1962).

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 maybe 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-bearing 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.
16 QUALITY OF SURFACE WATERS, 1960

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 (1962) recommends that copper should not exceed 1. 0 ppm 

in drinking and culinary water.

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. 05 ppm are significant, as this concentration is the 

upper limit for drinking water in the standards adopted by the 

U. S. Public Health Service (1962). 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 surf ace waters it is present only in trace quantities, but more may be 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 water does not cause serious effects on health, but 

produces undesirable esthetic effects. The U. S. Public Health 

Service (1962, p. 55) recommends that the zinc content not exceed 

5 ppm in drinking and culinary water.
COMPOSITION OF SURFACE WATERS 17

Barium (Ba)

Barium may replace potassium in some of the igneous rock 

minerals, especially feldspar and barium sulfate (barite) is 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 (1962) states that water containing concentrations of barium in excess of 1 ppmis not suitable 

for drinking and culinary use because of the serious toxic effects 

of barium on heart, blood vessels, and nerves.

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. It resembles chloride in that it tends to be 

concentrated in sea water.

Iodide (I)

Iodide is considerably less abundant both in rocks and water 

thanbromine. Measurable amounts maybe 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 Bahama (1950, p r 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 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, possibility of boiler failure, and loss of flow.
18 QUALITY OF SURFACE WATERS, 1960

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.

Generally, bicarbonate and carbonate determine the proportions of "carbonate" hardness of water. Carbonate hardness is 

the amount of hardness chemically equivalent to the amount of 

bicarbonate and carbonate in solution. Carbonate hardness is approximately equal to the amount of hardness that is removed from 

water by boiling.

Noncarbonate hardness is the difference between the hardness 

calculated from the total amount of calcium and magnesium in solution and the carbonate hardness. If the carbonate hardness (expressed as calcium carbonate) equal the amount of calcium and 

magnesium hardness (also expressed as calcium carbonate) there 

is no noncarbonate hardness. Noncarbonate hardness is about 

equal to the amount of hardness remaining after water is boiled. 

The scale formed at high temperatures by the evaporation of water 

containing noncarbonate hardness commonly is tough, heat resistant, and difficult to remove.

Although many people talk about soft water and hard water, 

there has been no firm line of demarcation. Water that seems 

hard to an easterner may seem soft to a westerner. In this report hardness of water is classified as follows:

Hardness range

(calcium carbonate

in ppm)

0-60

61-120

121-180

more than 180

Hardness description

Soft 

Moderately hard

Hard 

Very hard

For public use, water with hardness above 200 parts per million 

generally requires softening treatment (Durfor and Decker, 1964, 

p. 23-27).

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 acids and weak bases that hydrolyze to give hydrogen ions. Sulfates of iron and aluminum in mine and industrial
COMPOSITION OF SURFACE WATERS 19

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. 

Sodium-adsorption-ratio is expressed by the equation:

SAR= Na+

Ca+++Mg

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

waters).

Waters are divided into four classes with respect to sodium 

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

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

100 micromhos per centimeter the dividing points are at SAR values of 10, 18, and 26, but at 5,000 micromhos the corresponding 

dividing points are SAR values of approximately 2. 5, 6. 5, and 11. 

Waters range in respect to sodium hazard from those which can 

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

Specific conductance (micromhos per centimeter at 25°C)

Specif ic conductance is a convenient, rapid determination used 

to estimate the amount of dissolved solids in water. It is a measure of the ability of water to transmit a small electrical current 

(see p. 8). The more dissolved solids in water that can transmit 

electricity the greater the specif ic conductance of the water. Commonly, the amount of dissolved solids (in parts per million) is 

about 65 percent of the specific conductance (in micromhos). This 

relation is not constant from stream to stream or from well to 

well and it may even vary in the same source with changes in the 

composition of the water (Durfor and Becker, 1964, p. 27-29).

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.
20 QUALITY OF SURFACE WATERS, 1960

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 maybe 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 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 colorless than 

15 units generally passes unnoticed (U. S. Public Health Service, 

1962). Some swamp waters have natural color in excess of 300 

units.

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 above standard (see p. 8).
COMPOSITION OF SURFACE WATERS 21

Oxygen consumed

Oxygen consumed is a measure of the amount of oxygen required to oxidize unstable materials in water and may be correlated 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 import 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 presence 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 

consumecLunknowingly. Reported thresholds of detection of taste 

and odor range from 0. 001 to 0. 01 ppm.

Detergents (ABS). --The chief surfactant in commercial detergents is anionic alkylbenzenesulfonate (ABS). ABS and other 

anionic surfactants resist chemical oxidation and biological breakdown. Their persistence in water over long periods of time contributes to pollution of both ground water and surf ace water. Some 

of the effects produced from detergent pollution are unpleasant 

taste, odor, and foaming (Wyman, Robertson, and Page, 1962). 

Although the physiological implications of ABS to human beings is 

unknown, prolonged ingestion of this material by rats is believed 

to be nontoxic (Paynter, 1960). The U. S. Public Health Service 

(1962) recommends that ABS should not exceed 0. 5 ppm in drinking 

and culinary waters.

Temperature

Temperature is an important factor in property determining 

the quality of water. This is very evident for such a direct use
22 QUALITY OF SURFACE WATERS, 1960

as an industrial coolant. Temperature is also important, butperhaps 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 

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.
COMPOSITION OF SURFACE WATERS 23

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). Although turbidity 

does not directly measure the safety of drinking water, it is related to the consumers acceptance of the water. A level of 5 units 

of turbidity becomes objectionable to a considerable number of 

people (U.S. Public Health, 1962).

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 

rock transformation. This natural process maybe 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 solid 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 in the sandsize 

(larger than 0. 062 mm) range do not appear to be affected byflocculation 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
24 QUALITY OF SURFACE WATERS, 1960

degree of flocculation present, time in transport, and characteristics of the transporting flow. The flow characteristics include 

velocity of water, turbulence, and the depth, width, and roughness 

of the channel. As a result of these variable characteristics, the 

size of particles transported, as well as the total sediment load, 

is in constant adjustment with the characteristics and physical 

features of the stream and drainage area.

STREAMFLOW

Most of the records of stream discharge, used in conjunction 

with the chemical analyses and in the computation of sediment 

loads in this volume, are published in Geological Survey State 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

Many municipal, State, and Federal agencies gave assistance 

in collecting records for chemical-quality and sediment investigations. The table on page 27 lists the State and local agencies that 

cooperated in water-quality investigations in the drainage basins 

included in this volume and the locations of the quality-of-water 

district offices responsible for the data collected.

The Bureau of Reclamation, United States Department of the 

Interior, continued financial assistance for the operation of some 

chemical-quality and sediment investigations in the Colorado River 

basin in Arizona, Colorado, New Mexico, Utah, and Wyoming, for 

chemical-quality investigations at Lake Mead and below Hoover 

Dam on the Colorado River, and for water-quality investigations 

in the Pacific slope basins in Oregon and lower Columbia River 

basin.

Assistance was also provided by the Metropolitan Water District of Southern California at La Verne, Calif., in the analyses 

of samples for the chemical-quality program at Lake Mead.

In addition to the cooperative programs, many stations were 

operated from funds appropriated directly to the Geological Survey. Chemical-quality and sediment load investigations in the Colorado River basin in Arizona, Colorado, New Mexico, and Utah 

have been a continuing Federal project since 1925.

DIVISION OF WORK

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

Resources Division of the Geological Survey, L. B. Leopold, 

chief hydrologist, and S. K. Love, chief, Quality of Water Branch. 

The records were collected and prepared for publications under 

the supervision of district chemists as follows: In California, 

Eugene Brown; Colorado, Wyoming, Nevada, and Utah, J. G. Connor; Idaho, Montana, Oregon, and Washington, L. B. Laird; and 

in Arizona and New Mexico, J. M. Stow. Any additional information on file may be obtained by writing or visiting the responsible
