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 combines with the iron to form ferric ions (Fe+++). This gives the water a red rust coloring. gps wilhelmshaven
