Rapid and reliable monitoring and surveillance methods are essential for keeping a close watch on the water quality, human health and environment. Hence it becomes important to monitor and analyse water of bore-wells used for drinking and irrigational purposes. In the present study water quality of bore-wells of Kolar road area has been done seasonally during the year of 2008-09 for different parameters i.e., temperature, pH, EC, free CO2, chloride, total alkalinity, T-H, Ca-H, Mg-H, D.O., B.O.D., C.O.D., Nitrate, Sulphate and bacteriological analyses has been done by multiple tube technique by Mac’ Conkey Broth Soln, reported n Index/100mL, are found beyond the permissible limit of 10/100mL at some sampling station.
