What is total iron?
Summary
What is total iron?
Answer
Iron can exist in water in several different forms:

 -Ferrous iron (Fe2+)
-Ferric iron (Fe3+)
-Complexed iron, in which iron is bound with various chemicals such as EDTA
-Iron oxides, such as rust.

Total iron includes all of these forms. Ferrous iron is soluble in water and is commonly found in ground water. Once exposed to air, ferrous iron quickly oxidizes to ferric iron.
