Groundwater may contain ferrous iron without discoloration or turbidity. However, when exposed to the atmosphere, ferrous iron oxidizes to ferric iron giving an objectionable reddish-brown colour to the water.
Iron also promotes the growth of "iron bacteria" resulting in a slimy coating on the piping. At levels above 0.3 mg/l, iron stains laundry and plumbing fixtures. There is usually no noticeable taste at iron concentrations below 0.3 mg/l, although turbidity and colour may develop.
