Water Treatment : Iron
What is Iron In Well Water?
The presence of Iron
is a very common water quality problem, particularly in water from deep
and shallow wells. As rain falls or snow melts on the land surface, and
water seeps through iron-bearing soil and rock, iron can be dissolved
into the water. In some cases, iron can also result from corrosion of
iron or steel well casing or water pipes.
Water containing even a significant quantity of
iron may appear clear when drawn, but will rapidly turn red upon
exposure to air. This process is called oxidation, and involves the
conversion of ferrous (dissolved - clear water iron) iron, which is
highly soluble, to ferric (precipitated - red water iron) iron, which is
largely insoluble. The ferric iron then causes red/brown staining on
clothes, fixtures, etc. Iron water also has an unpleasant metallic
Water Iron a Health Concern?
Iron in well water usually does not present a health problem. Iron
bacteria, that may be associated with iron in water, are not
considered a health problem.
What Are The Problems With Well Water Iron
Iron in water can cause yellow, red, or brown stains on laundry, dishes,
and plumbing fixtures such as sinks. In addition, iron can clog wells,
pumps, sprinklers, and other devices such as dishwashers, which can lead
to costly repairs. Iron gives a metallic taste to water, and can affect
foods and beverages we drink such as tea and coffee.
