A frequent cause of musty, earthy odors, especially toward
the end of the summer, is naturally occurring organic
compounds derived from the decay of plant material in
lakes and reservoirs. The odors can be objectionable, but
generally are not harmful to health. However, odors can be
caused by other constituents as well, so you may want to
call your local Health Department and mention the odor to
them.
In some parts of the country, drinking water can contain
the chemical hydrogen sulfide gas, which smells like
rotten eggs. This can occur when water comes into contact
with organic matter or with some minerals, such as pyrite.
The situation mostly occurs as ground water filters
through organic material or rocks.
Some solutions to the unpleasant odor are discussed on
Water Doctors and NSF Consumer Information.
The best way to find out what is in your water is to have
the water tested by a state certified laboratory. A list
of these labs is available from your State Certification
Officer. |
