ABSTRACT

 

Fresh Water bodies constitute a very small total area of earth or even of land surface and an external small fraction of the total water but from the view point of human use these are among the most important natural water resources. Man uses water for many purposes. For domestic purpose, we prefer to use soft water. However several statistical studies have demonstrated a highly significant inverse relationship between cardiovascular disease mortality and water hardness even when other environmental and socioeconomic factors are taken into account. Pure water is poor conductor of electricity but when electrolytes in form of mineral dissolves, it imparts conductivity. Higher the concentration of ions, more is its electrical conductance (i.e. lesser the resistance) The total hardness of water is the sum of the concentration of alkaline earth metal cations present in it. Calcium and magnesium is found in all natural water and its source lies in the rocks from which it is leached. Its concentration varies greatly in natural water depending upon the nature of basin. By measuring electrical conductivity of under ground water, the salt concentration can be easily assessed, so that proper location can be selected for ground water exploration, which is useful for health and proper functioning of cardiovascular system.
