Manohar.G.N , Harish Raju .M , Sripathy L and Renuka C

Eight groundwater samples of Chintamani Taluk of Chikkaballapur District were analysed for the Physicochemical properties like pH, TDS, EC, Alkalinity, Total Hardness, Ca++, Mg++, NO3 -, SO4 2-, F- and Pb following the standard guidelines of APHA (1998). Out of eight ground water samples six samples were found to have nitrate level above the permissible limit (45mg\L), all the fluoride levels close to the permissible limit (1.5 mg\L). Six samples were found to have Pb level greater than the permissible limit (0.01 mg\L). The above mentioned water quality variables are hazardous to the biological system which emphasises the need for improvising the water quality.
