Issue: Water drawn from a well and in some cases municipal water supplies may contain ferrous or “clear water” iron.
Water that is clear when drawn but changes to a yellow or rusty color upon standing is known as ferrous or clear water iron. This iron has not yet been exposed to oxygen and therefore has not “rusted” or oxidized. Ferrous iron is totally dissolved in water, and is readily converted to ferric iron (red water iron) in the presence of any air or oxidizing material.
Symptoms: Staining to Sinks, Bathtubs & Clothing; Taste
It doesn’t take much time to realize that you have iron in your water supply. Rust and black colored stains on sinks, toilets and showers, metallic taste and stains to laundry are clear signs that you have iron or manganese in your household’s water. Iron and manganese sometimes occur in water together.
