Iron Test
Most natural waters contain iron, varying from trace to very large amounts in various forms. In the dissolved
state (ferrous), iron water is often colorless. Upon exposure to air, or an oxidized state, ferrous iron will undergo
a chemical reaction to the suspended (ferric) state causing discoloration, staining, and possibly an objection-
able taste. Several methods are available for iron removal, the selection of which is dependent upon the state in
which it exists.
