People are
becoming increasingly concerned about the safety of their water. Current
improvements in analytical methods allow for detection of impurities at very
low concentrations in water. Consequently, water supplies once considered to be
pure are found to contain various contaminants, very often from natural
sources, and usually below harmful concentrations. Water can dissolve thousands
of substances, some of which do not dissolve and form a suspension in water. Therefore,
we must not expect pure water, but we want to be sure of safe water.
Water systems in Germany
that serve more than 1000 residents are periodically tested for many kinds of
contamination. The only people who may have a reason for testing their water
are the owners of individual water supplies that have some indication of a
problem, such as odor or taste. The presence of nearby pollutant sources also
may be a good reason for a water test.
This circular should be
considered an introduction to some specific water problems one might encounter,
and how one should go about identifying and solving them. For more specific
