It only takes a miniscule amount of iron in water to cause staining, as little as 0.3 parts per million (ppm). Iron occurs naturally in water in soluble form as ferrous iron (bivalent iron: Fe+2) or non-soluble form as ferric iron (trivalent iron: Fe+3). If you suspect your drinking water may be too high in iron, you can contact your state water department to determine if, and how, your water should be tested.
