WATER
The chemical character of the ground-water in the
East St. Louis area is known from the analyses of water
from 183 wells. The results of the analyses are given
in table 37. The constituents listed in the table are given
in ionic form in parts per million. The analyses of water
from wells were made by the Chemistry Section of the
State Water Survey. Chemical analyses of water from
wells at several sites in the area are made monthly by the
chemistry section. The locations of selected sites are
given in figure 70. The sampling periods are listed in
table 38, which provides a summary of the results of
periodical chemical analyses of water from selected
wells.
Ground water in the East St. Louis area varies in
quality at different geographical locations. The quality
of water also varies with the depth of wells, and may
often be influenced by the rate of pumping and the idle
period and time of pumping prior to collection of the
sample. Bruin and Smith (1953) noted that relatively
shallow wells of a depth less than 50 feet are in general
quite highly mineralized and frequently have a high
chloride content. Water samples from wells in heavily
pumped areas often have high sulfate and iron contents
and a high hardness.
Induced infiltration of water from the Mississippi
River affects the chemical quality and temperature of
water in wells at many sites. All other factors being
equal, the closer the well is to the river the greater will
be the effect of induced infiltration on the quality and
temperature of water in the well. In most of the analyses
in tables 37 and 38 the effect of induced infiltration of
river water is not evident. Data in figure 71 illustrate
the effect of induced infiltration of water from the river
