Content Details: 

Ground water is an essential component of daily life support system in India, especially in the rural areas where it is the only resource of drinking water. An excess amount of iron in the ground water which can create health and economic complications. Though iron is an essential element required for the human body system but continuous consumption of water containing excess iron may lead to stomach problems, nausea, vomiting, effects on skin, etc. High iron is associated with discoloration, turbidity and taste problems, in addition to forming slime and iron accumulation in pipes. Iron also promotes the growth of certain types of chlorine-tolerant microorganisms in water distribution systems, including organisms harmful to human health and also increases the cost of cleaning and sterilizing systems. As per WHO, the upper limit of iron in drinking water is 0.3 mg/l, but there are 297 districts of 24 Indian states having underground water contaminated by excessive concentration of iron.
