CONVERSION OF ANALYSES.
The tedious work of converting the analyses (most of which were
originally expressed in hypothetical forms in grains per gallon) to
ionic forms in parts per million has been largely done by Gertrude E.
Goodman, to whom credit is due for reducing them to the standard
form and thus rendering them available for comparison. In this
work conversion tables prepared for the various salts by R. B. Dole
from the atomic weights of 1897 (oxygen =16.00) have been used.
In amounts of less than 1 part per million by weight two decimals
have in most analyses been retained; in amounts of 1 to 10 parts, one
decimal; and amounts greater than 10 parts are expressed in the
nearest unit. The totals by summation are given as a check on the
other figures as well as to show the approximate total solid contents.
Where sodium and potassium are reported together in an analysis
the reacting value has been calculated on the assumption that the
figures given represent only sodium; similarly where calcium and
magnesium or iron and aluminum are reported together the values
are assumed to be all calcium or all iron.
The properties of reaction have in each analysis been made to
aggregate 100 per cent without tertiary alkalinity, any excess from
the other properties being combined with this property.
Temperatures are expressed in degrees Fahrenheit in the text and
in both Fahrenheit and Centigrade in the analyses.
A few typographical errors have been corrected by comparing
analyses that appear in two or more publications.
The notes concerning the principal characteristics of the waters,
as shown by the analyses, have been made by Mr. Herman Stabler,
who also calculated the reacting values and the properties of reaction.
Many of the analyses report only the most common substances,
and a few contain questionable figures, but all are believed to show
the general character of the waters and, in the absence of better
analyses, are presented as furnishing the best information available
concerning the chemical character of the springs. Two or more
analyses of water from the same spring are given wherever they are
available, as they afford valuable checks on unusually high amounts
of certain substances. The widely differing results of analyses of
water of the same spring by different persons may be ascribed to
actual differences in the composition of the water at different times.
