QUALITY OF SURFACE WATERS 

OF THE UNITED STATES, 1965

PARTS 7 and 8

INTRODUCTION

The quality-of-water investigations of the United States Geological Survey are concerned with chemical and physical characteristics of the surface and ground water supplies of the Nation. 

Most of the investigations carried on in cooperation with State 

and Federal agencies deal with the amounts of matter in solution 

and in suspension in streams.

The record of chemical analysis, suspended sediment, and 

temperature of surface waters given in this volume serve as a 

basis for determining the suitability of waters for various uses. 

The flow and water quality of a stream are related to variations 

in rainfall and other forms of precipitation. In general, lower 

concentrations of dissolved solids may be expected during periods 

of high flow than during periods of low flow. Conversely, the suspended solids in some streams may change materially with relatively small variations in flow, whereas for other streams the 

quality of the water may remain relatively uniform throughout 

large ranges in discharge.

The Geological Survey has published annual records of chemical quality, suspended sediment, and water temperature since 

1941. 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. From 1950 to 1958, the records were published in four 

volumes and from 1959 to 1963 in five volumes. Beginning with 

the 1964 water year, water quality records obtained by the Geological Survey were published in a new series of annual releases 

on a state-boundary basis. These records are then published in 

six volumes in the Geological Survey water-supply paper series. 

The drainage basins covered in the six volumes are shown in 

Figure 1. The data given in this report were collected during the 

water year October 1,1964 to September 30,1965. 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.

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 2 digits 

followed by a hyphen and a 6-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 location of the station in the standard downstream order within each of the 16 parts 

(Fig. 1). The assigned numbers are in numerical order but are

not consecutive. They are so selected from the complete 6-digitnumber 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.

Descriptive statements are given for each sampling station 

where chemical analyses, temperature measurements, or sediment determinations have been made. These statements include 

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, 1965, the Geological Survey maintained 127 stations on 61 streams for the 

study of chemical and physical characteristics of surface water. 

Samples were collected daily and monthly at 125 of these locations 

for chemical-quality studies. Samples also were collected less 

frequently at many other points. Water temperatures were measured continuously at 2 and daily at 83 stations. All surface 

water samples collected and analyzed during the year have not 

been included. Single analyses made of 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 28.

Quantities of suspended sediment are reported for 34 stations 

during the year ending September 30, 1965. 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 22 of the 

stations.

COLLECTION AND EXAMINATION OF SAMPLES

Quality of water stations usually are located at or near points 

on streams where streamflow is measured by the U.S. Geological 

Survey. The concentration of solutes and sediments at different
4 QUALITY OF SURFACE WATERS, 1965

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 velocityweighted mean concentration for the section.

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 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 the method of 10-day periods or the equivalent of three 

composite samples per month generally is practiced, modifications 

usually are 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.
COLLECTION AND EXAMINATION OF SAMPLES

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 in order that the data 

would be relatively unaffected by diurnal variations in temperature. 

Most large streams have a small diurnal variation in water 

temperature; small, shallow streams may have a daily range of 

several degrees and may follow closely the changes in air temperature. The thermometers used for determining water temperature were accurate to plus or minus 0.5°F.

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

the monthly averages of maximum daily and minimum daily 

temperatures.

SEDIMENT

In general, suspended-sediment samples were collected daily 

with depth-integrating cable-suspended samples (U.S. InterAgency, 1963, and 1952.) from a fixed sampling point at one vertical in the cross section. A 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 a day at 

most sampling stations.

Sediment concentrations were determined by filtrationevaporation 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
6 QUALITY OF SURFACE WATERS, 1965

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 before 

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

periods of similar discharge. The estimates were further guided 

by weather conditions and sediment discharge for other stations.

In many instances where there were no observations for 

several days, the suspended-sediment loads for individual days are 

not estimated, because numerous factors influencing the quantities 

of transported sediment made it very difficult to make accurate 

estimates for individual days. However, estimated loads of suspended sediment for missing days in an 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. Inter-Agency, 

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

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

(U.S. Inter-Agency, 1943).
EXPRESSION OF RESULTS

EXPRESSION OF RESULTS

The quantities of solute concentrations analyzed in the laboratory are measured by weight-volume units (milligrams per liter) 

and for reporting, are converted to weight-weight units (parts per 

million). 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 (ppm).

Equivalents per million are not reported, but they can be 

calculated easily from the parts per million data. 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 x(b) multiplying the concentration (in ppm) by the 

reciprocals of the combining weights. The following table lists 

the reciprocals of the combining weights of cations and anions 

generally reported in water analyses.

The conversion factors are computed from atomic weights 

based on carbon-12 (International Union of Pure and Applied 

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 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 

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. 25) and the temperature in degrees 

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

scale proposed by Hazen (1892). 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.
EXPRESSION OF RESULTS 9

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 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. A dischargeweighted 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. For most streams, dischargeweighted averages are lower than arithmetical averages because 

at times of high discharge the rivers generally have low 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.

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 concentrations 

in parts per million by the daily mean discharge in cubic feet per 

second, and the conversion factor, normally 0.0027.

Particle size analyses are expressed in percentages of 

material finer than classified sizes (in millimeters). The size 

classification used in this report agrees closely with recommendations made by the American Geophysical Union Subcommittee 

on sediment terminology (Lane and others, 1947). The particle 

size distributions given in this report are not necessarily representative of the particle sizes of sediment in transport in the 

natural stream. Most of the organic matter is removed and the 

sample is subjected to mechanical and chemical dispersion before 

analysis of the silt and clay.
10 QUALITY OF SURFACE WATERS, 1965

COMPOSITION OF SURFACE WATERS

All natural waters contain dissolved 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. Ground water 

is generally more highly mineralized than surface runoff because 

it remains in contact with the rocks and soils for much longer 

periods. Some streams are fed by both surface runoff and 

ground water from springs or seeps. Such streams reflect the 

chemical character of their concentrated underground sources 

during dry periods and are more dilute during periods of heavy 

rainfall. 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 water use. The results of analyses generally 

include silica, iron, calcium, magnesium, sodium, potassium (or 

sodium and potassium together calculated as sodium), lithium, 

carbonate, bicarbonate, sulfate, chloride, fluoride, nitrate, boron, 

pH, dissolved solids, and specific conductance. Aluminum, manganese, color, acidity, dissolved oxygen, 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, and other trace elements 

are determined occasionally for a few streams in connection with 

specific problems and the results are reported. 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 in the tables.

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
COMPOSITION OF SURFACE WATERS 11

usually is removed from feed water for high-pressure boilers. 

Silica also forms troublesome deposits on the blades of steam turbines.

Aluminum (Al)

Aluminum is usually present only in negligible quantities in 

natural waters except in areas where the waters have been in contact with the more soluble rocks of high aluminum content such as 

bauxite and certain shales. Acid waters often contain large amounts 

of aluminum. It may be troublesome in feed waters where it tends 

to be deposited as a scale on boiler tubes.

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 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. 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 

silicious sands contain less than 10 parts per million of calcium;
12 QUALITY OF SURFACE WATERS, 1965

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 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, sodium and potassium values that are calculated 

and reported as sodium are indicated by footnote.

Lithium (Li)

Data concerning the quantity of lithium in water are scarce. 

It is usually found in small amounts in thermal springs and saline
COMPOSITION OF SURFACE WATERS 13

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 (HCCL,CCL, 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, alkalinity in 

moderate amounts 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 (SO )

Sulfate is dissolved from many rocks and soils in especially 

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

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

in considerable quantities in waters from mines. Sulfate in waters 

that contain much calcium and magnesium causes the formation of 

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

the water.

Chloride (Cl)

Chloride is dissolved from rock materials in all parts of the 

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

chloride, whereas streams in arid or semiarid regions may contain several hundred parts per million of chloride leached from 

soils and rocks, especially where the streams receive return 

drainage from irrigated lands or are affected by ground-waterinflow carrying appreciable quantities of chloride. Large quan-
14 QUALITY OF SURFACE WATERS, 1965

tities of chloride in water that contains a high content of calcium 

and magnesium increases the water's corrosiveness.

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 (NCL)

Nitrate in water is considered a final oxidation product of 

nitrogenous material and may indicate contamination by sewage or 

other organic matter. The quantities of nitrate present in surface 

waters are generally less than 5 parts per million (as NCL) 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 NCL) may contribute to methemoglobinemia ("blue babies") (Faucett and Miller, 1946), and more 

recent investigations conducted in Ohio show that drinking water 

containing nitrates in the range of 44 to 88 ppm (as NCL) may 

cause methemoglobinemia (Waring, 1949). A report published by 

the National Research Council, Maxcy (1950) concludes that a 

nitrate content in excess of 44 parts per million (as NCL) should 

be regarded as unsafe for infant feeding. U.S. Public Health 

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

Phosphate (PO )

Phosphorus is an essential element in the growth of plants and 

animals. Some sources that contribute nitrate, such as organic
COMPOSITION OF SURFACE WATERS 15

wastes are also important sources of phosphate. 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 of ten 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 surf ace 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.

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).
16 QUALITY OF SURFACE WATERS, 1965 

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 may be 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*

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.
COMPOSITION OF SURFACE WATERS 17

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) 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 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.

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 ppm is not suitable 

for drinking and culinary use because of the serious toxic effects 

of barium on.heart, blood vessels, and nerves.
18 QUALITY OF SURFACE WATERS, 1965 

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 

than bromine. 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) 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.

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.
COMPOSITION OF SURFACE WATERS 19

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) equals 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

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 

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
20 QUALITY OF SURFACE WATERS, 1965

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 

2

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

waters).

Waters are divided into four classes with respect to sodium 

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

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

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)

Specific 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 specific 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.

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.
COMPOSITION OF SURFACE WATERS 21

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 the ground. In some areas objectionable color in 

water results from industrial wastes and sewage. Clear deep 

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

the water molecules. Water for domestic use and some industrial 

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

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).

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.
22 QUALITY OF SURFACE WATERS, 1965

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).

Dissolved oxygen (DO)

Adequate dissolved oxygen is necessary for the life of fish 

and other aquatic organisms and is an indicator for corrosivity 

of water, photosynthetic activity, and septicity. It is one of the 

most important indicators of the condition of a water supply 

for biological, chemical and sanitary investigations (Rose, 1965).

Biochemical oxygen demand (BOD)

Biochemical oxygen demand is a measure of the oxygen required to oxidize the carbonaceous organic material usable as a 

source of food by aerobic organisms.

Chemical oxygen demand (COD)

Chemical oxygen demand indicates the quantity of oxidizable 

compounds present in a water and will vary with water compositions, concentration of reagent, temperature, period of 

contact, and other factors.

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 

consumed unknowingly. Reported thresholds of detection of taste 

and odor range from 0.001 to 0.01 ppm.
COMPOSITION OF SURFACE WATERS 23

Most probable number (MPN). An index for determining the 

extent of pollution in water is the most probable number which 

is a direct count of coliform colonies per 100 milliliters of water.

Detergents (MBAS). Anionic surfactants (methylene blue 

active substance, MBAS) in detergents resist chemical oxidation 

and biological breakdown. Their persistence in water over long 

periods of time contributes to pollution of both ground water and 

surface water. Some of the effects produced from detergent 

pollution are unpleasant taste, odor, and foaming (Wayman, 

and others, 1962). Although the physiological implications of 

MBAS 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 MBAS 

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 

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.

Surface 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. 

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 to the streambed. 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 result in a separation 

of the water volume into a circulating upper portion and a noncirculating lower portion. Separating the two is a stratum of 

water of variable vertical thickness in which the temperature
24 QUALITY OF SURFACE WATERS, 1965

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 oxygenutilizing 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.

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 or 

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
STREAMFLOW 25

sediment is that part 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 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 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 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 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 The Geological Survey 

water-supply paper series, "Surface Water Supply of the United 

States, 1961-65." 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
26 QUALITY OF SURFACE WATERS, 1965

are either daily mean discharges or discharges obtained at the 

time samples were collected and computed from a stage-discharge 

relation or from a discharge measurement.

COOPERATION

Many of the investigations were supported by funds appropriated directly to the Geological Survey. Studies of suspendedsediment loads in the middle Rio Grande in New Mexico were 

started in 1948 as a Federal project.

Financial assistance was furnished by the Bureau of Reclamation, U.S. Department of the Interior, for some investigations in 

the Arkansas River basin in Kansas and Oklahoma, and the Rio 

Grande in New Mexico. The Soil Conservation Service, U.S. 

Department of Agriculture, assisted with special sediment studies 

in the Arkansas River basin in Arkansas, and in the Rio Grande 

basin in New Mexico. The Corps of Engineers, U.S. Army, 

provided funds and determined the sediment concentration and 

particle size bed material in connection with the sediment 

investigations of the Mississippi River at St. Louis, Mo. The 

Corps also assisted with investigations in Arkansas, Mississippi, 

New Mexico, and Texas.

Records of 10 stations in the Rio Grande basin were furnished 

by the U.S. Department of Agriculture in cooperation with the 

International Boundary and Water Commission.

The table on p. 29 lists State and local agencies that cooperated 

in quality-of-water investigations included in this volume, and the 

locations of district offices responsible for the data collected.

SEEPAGE INVESTIGATION 

RIO GRANDE FROM LOBATOS-, COLORADO TO EMBUDO

A seepage or low-flow investigation was made on Oct. 7-8, 1964, to study gains and losses 

to the gaging station at Embudo, N. Hex., which is approximately 68 river miles. Most of the u

plains. The river still flows through canyons on the lower section of the reach, but it contai

irrigation developments. All known triburary inflows were measured. The results of discharge 

analyses were collected at each measuring site. This is the first investigation in which chemi

and 1963 involved only discharge measurements.
