DEFINITION OF TERMS 

Dissolved solids. Consist mainly of the dissolved mineral constitutents in water and 

are represented by the residue that remains after filtration, evaporation, and d~ying at a temperature of 180°C. 

Hardness. A property of water which causes an increase in the amount of soap that 

is needed to produce foam or lather. Hardness is produced almost completely by 

the presence of calcium and magnesium salts in solution. Carbonate hardnesr is 

represented by the carbonate and bicarbonate salts of calcium and magnesium. 

Noncarbonate hardness is represented by all other salts of calcium and magnesium. 

Hardness is expressed conventionally in terms of an equivalent quantity of calcium 

carbonate. The following scale may assist the reader in appraising hardness:

Milligrams per liter (mg/1). A unit for expressing the concentration of chemical c':lnstituents by weight per unit of volume. It is numerically equal to parts per milF0n 

(ppm) in the analyses used in this publication. 

pH. A measure of the hydrogen-ion concentration of a solution. A pH unit is 

expressed as the negative log10 of the hydrogen-ion concentration. The pH of pnre 

water is 7; acid water has a smaller pH and alkaline water a larger pH. 

Specific conductance. A measure of the ability of a water to conduct an electrical 

current. It is expressed in micromhos per centimeter at 25°C. Pure water has a 

very small electrical conductance, but the conductance increases with increas~ng 

concentration of dissolved minerals.

CHEMICAL QUALITY OF MICHIGAN STREAMS 

By WARREN W. WOOD 

ABSTRACT 

Concentrations of chemical constituents of Michigan 

streams exhibit regional patterns that are primarily a 

function of geology and evapotranspiration. However, 

in some areas waste disposal by municipal and industrial organizations has altered the natural distribution 

and concentrations of dissolved material. Concentration 

and areal distribution of chemical constitutents were 

found to change very little from high spring to low 

summer flow conditions. 

INTRODUCTION 

Chemical quality of streams in Michigan is 

becoming a matter of increasing public interest 

and concern. With this public awareness, there 

is an increase in demand for water quality information by representatives of industry, 

recreation, and local units of government. This 

report is intended to provide a source of chemical quality information for these groups and 

also to present information for statewide comparison and water management planning. 

Chemical analyses of samples collected from 

streams have been published by the U.S. Geological Survey ( 1943-65) in a series of watersupply papers. These analyses were made from 

samples collected for specific areal projects as 

well as those collected from miscellaneous sites 

throughout the State. Detailed investigations 

conducted by the Michigan Water Resources 

Commission also are a source of water quality 

information on selected areas. (See "Selected 

references.") However, for this report it was 

deemed desirable to gather data over the entire 

State from all types of strean1s under conditions 

which are likely to indicate the normal range 

in chemical quality. 

To aid in defining the chemical quality of 

1 

stream water, samples were collected at arproximately 200 gaging stations (fig. 1). One series 

of san1ples was collected in late March and early 

April 1967 when streamflow was high. T'"~ second set was collected in late August and early 

September 1967 under conditions of low 

streamflow. 

It is recognized that the hydrologic distribution of gaging stations is not ideal for this type 

of sampling because many tributaries and 

several major rivers are not represented. However, the advantages of having instantaneous 

discharge in addition to long periods of discharge records covering a relatively larg:l number of areally well-distributed sample dtes is 

considered to compensate for the lack of a complete sample coverage. 

It was intended that analysis of these s!lmples 

would ( 1) give comparable values over the entire area of the State under conditions which 

produce extremes in natural water quality, (2) 

give regional variation patterns in chemical 

quality so that reasonable estin1ates of water 

quality could be made in the absence of specific 

analyses, (3) give values to which future measurements may be compared for evaluating 

changes in water quality, and ( 4) give a 

frmnework on which future and ~tailed 

water-quality studies can be conducted.

STREAI\-1 QUALITY OBSERVATIONS 

FIELD METHODS OF ANALYSIS 

Samples of water from the stream were collected by personnel of the Michigan District of 

the U.S. Geological Survey during their regular 

visits to the gaging stations. The samples were 

collected in disposable plastic bottles and returned to the district office where chemical 

analyses were performed using field methods. 

The time between collection and analysis averaged about 2 weeks. To verify the stability of 

the parameters during transportation and storage, multiple samples were collected at several 

sites and analyzed at time intervals up to 1 

month in length. There were no changes in the 

measured constituents greater than those 

expected from analytical error. 

Field methods of analysis consisted of using 

mercuric nitrate for chloride determination 

(American Public Health Association, 1965) 

turbidimetric method for sulfate, colorimetric 

EDTA (ethylenediaminetetraacetic acid) for 

hardness, colorilnetric and potentiometric titration for bicarbonate, and a conductivity meter 

(accuracy within 2 percent) for specific conductance. A glass electrode and pH meter were 

used to determine pH. Dissolved solids were determined by multiplying specific conductance by 

0.65. Results obtained from field methods were 

within 5 percent of the values obtained from 

laboratory analyses of 40 duplicate samples. 

BASIC QUALITY OF STREAMS 

Figures 2 and 3 illustrate the distribution of 

the concentration of dissolved solids during 

periods of low and high flow, respectively. During high-flow conditions streams generally exhibit more dilute water due to the additions of 

large quantities of rain and snowmelt water. 

However, the change in concentration between 

extreme flow conditions is relatively small. 

Hardness of stream water (figs. 4, 5) follows 

the same general pattern as the dissolved solids 

because the stream water is of the calcium 

magnesium bicarbonate type. Chloride (figs. 6, 

7) and sulfate concentrations (figs. 8, 9) also 

follow the same distribution pattern. The chlo3 

ride content in most streams is generally lower 

than sulfate by a factor of about four. The sulfate ion is usually associated with calcium and 

magnesium which contribute to the hardness of 

the water. Chloride results from the presence of 

dissolved salts of calcium and sodium chloride. 

It is apparent from figures 2 through 9 that 

the mapped chemical constituents increase in 

concentration from north to south in l\1ichigan 

streams. Stream water in the western half of 

the northern peninsula contains the lowest concentrations of dissolved solids, whereas the 

southeastern section of the southern peninsula 

contains the highest concentrations. A sampling 

bias does however exist, because some stream 

gaging stations are located downstream from 

significant or unusual waste-water discharges. 

This bias is particularly noticeable in the Saginaw River system where industrial discharge, 

rather than natural controls, increased the chloride concentration of the stream. This condition 

is also apparent in the Grand, Kalamazoo, and 

Rouge River systems. 

The distribution patterns of major concentrations are controlled by differences in bedrock 

geology, thickness and composition of glacial 

drift, runoff, and evapotranspiration. Rocks of 

Precambrian age near the surface in the western 

half of the northern peninsula (Martin, 1936) 

are generally very siliceous in composition and 

would yield small amounts of soluble material 

to the streams. Because the lithology of the overlying glacial drift is influenced by the underlying 

bedrock lithology, the drift also yields small 

amounts of dissolved solids in this area. In the 

remainder of the State glacial erosion of the 

Paleozoic and Mesozoic age carbonaceous and 

argillaceous sediments has contributed fresh unweathered material to the glacial drift. This 

1naterial is readily soluble and consequently 

yields significant amounts of dissolved solids to 

the streams. 

Paleozoic age rocks locally contain highly 

mineralized water (Feth, 1965). Where these 

rocks are near the surface, they can contribute 

relatively large amounts of dissolved solids to 

the stream. This condition is illustrated in the 

southeastern section of the southern peninsula. 

Another factor contributing to the concentration distribution is the greater runoff in the 

northern part of the State (fig. 10). The difference in runoff is chiefly the result of smaller

greater precipitation (fig. 12) (Strommen, 

1967). 

In areas of urbanization the concentration of 

dissolved constituents varies as much as three 

orders of magnitude within a small stream 

segment. The dissolved materials come from 

combination sewers, septic tank effluents, waste 

treatment from municipal and industrial 

sources, and the use of soluble components for 

ice and dust control. Thus, the regional patterns 

of distribution and concentration are disrupteGl 

and the prediction of chemical quality is difficult. 

Records for the Clinton River basin, station 4-

1608 to 4-1655 (table 1), illustrate the large 

43' variation in chemical quality occurring in an 

urbanized environment. 

CONCLUSIONS 

evaporation, in 

All measured parameters illustrate distinct 

regional patterns of distribution that shift only 

slightly under conditions of high and low flow. 

Water in the streams is of the calcium magnesium bicarbonate type and remains this type 

12 
under high- and low-flow conditions. Concentrations of dissolved substances are generally 

lower during periods of high flow than during 

periods of low flmv. The higher concentrations 

that occasionally occur at spring high flows are 

attributed to inflo-w of water fr0111 combination 

of effluent fron1 sewers, fertilizers, and possibly 

road salt. Considering all paran1eters, there is a 

distinct tendency for the most dilute water to 

appear in the northern peninsula.
