The article presents an overview of physical and chemical transformations of various forms of iron which are typical for groundwater. As factors that influence the form and contents of iron, the presence of oxidants, pH, redox potential, ionic composition of water and the presence of organic compounds ( mainly humic substances) are considered.

Keywords:  iron, oxidation, pH, redox potential, humic substances.
