Natural sources. Iron is one of the most abundant metals in the Earth’s crust. It is found in natural fresh waters at levels ranging from 0.5 to 50 mg/litre.
Industry. Iron is used for various alloys, steel, in galvanisation process and other industrial processes.
Drinking water. Iron may be present in drinking-water as a result of the use of iron coagulants or the corrosion of steel and cast iron pipes during water distribution. There is usually no noticeable taste at iron concentrations below 0.3 mg/litre, and concentrations of 1–3 mg/litre can be acceptable for people drinking anaerobic well water.
Toxicity. Iron is an essential element in human nutrition. Estimates of the minimum daily requirement for iron depend on age, sex, physiological status and iron bioavailability and range from about 10 to 50mg/day. Portable water shoud contain iron not more than 0.2 mg/L. Ground water may contain iron at concentrations of several miligrams per litre.
