AbstractContamination of soil environment by heavy metals is becoming a widespread across the globe. The rapid industrialization and poor management of industrial effluent is creating a more chance of heavy metal pollution. Even at their exposure at minute level, heavy metals can have carcinogenic effect on human, animals and negative effect on soil microorganisms & crop plants. Excessive concentration of heavy metals viz., Cr, Cd, As, Ni, Se and Pb have been found in soils of agricultural land nearby cities, mines and industrial areas around the world. Although geogenic source of pollution has been observed for some trace elements in different parts of the world including India, the secondary sources of anthropogenic pollution are more dominant, localized and causing higher magnitude soil pollution. Use of contaminated water for agricultural purpose has affected the soil health and reduced the crop productivity in the long run. Remediation of heavy metal contaminated soil is a necessity in order to have a safe and healthy environment, which will sustain our life on the beautiful earth planet. This paper describes the heavy meal sources, type and status in India; remediation techniques and safety measures for safe use of industrial contaminated water.
