Iron is the most plentiful metal in the Earth’s crust. It’s not surprising that ground water absorbs this metal in varying concentrations. When groundwater containing iron is pumped into well distribution systems, it can cause unpleasant metallic tastes, staining of plumbing fixtures and plugging of faucet screens. Iron can also be responsible for staining of laundry and be accompanied by foul odors, gelatinous scum, and manganese which can produce black stains on porcelain, dishwashers, washing machines and clothes. Iron removal systems utilize oxidation and filtration, and depending on the type (ferrous, ferric, bacterial, etc.) and concentration, additional pre and post filtration may be needed to obtain satisfactory results.
