Rust - Wikipedia

Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the alytic presence of water or air moisture. Rust consists of hydrous iron(III) oxides (Fe2O3·nH2O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH)3), and is typically associated with the corrosion of refined iron. Given sufficient time, any

Well Water Iron Problems and Treatment Guide

2. Ferric Iron in Well Water. Also known as red water iron, ferric iron in well water is essentially clear water iron that has been exposed to oxygen – usually from the air, thereby oxidizing. Carbon dioxide leaves the water and the oxygen coines with the iron to form ferric ions (Fe+++). This gives the water a red rust coloring.
