The ground water day by day get deteriorate or polluted due to contamination of chemicals as well as fertilizer, which comes form Factories, and big farms as well as domestic effluents. The major ions which are responsible to maintain the quality of ground water are carbonate and bicarbonate, Chloride, sulphate, nitrate, phosphate, fluoride. These ions are present in anionic form. The cation and anion must be equal to maintain the quality of water cation such as Ca²⁺, Mg²⁺,Na⁺ and K⁺ are also present in ground water in form of hardness and salinity. 10 water samples are collected from Mehgao block (Bhind District) for pre-mansoon season (April to June 2005) The ionic concentration is expressed in mg/L.
