Surface water and groundwater samples of certain locations namely Kallambella, Bugudanahalli, Maidala, Honnudike, Kunigal, Kadaba and Hebbur, situated around Tumkur were assessed in the month of September 2008 for pH, EC and heavy metals Cd, Cu, Fe, Hg, Mn, Zn and Ni. The pH vales of surface waters were in alkaline range of 7.8-8.2 and are well within safe limits for crop production. The pH of ground-water was in the range of 7.6-8.4. The conductivity was in the range of 0.20-0.68 mS/cm and 0.34-2.44 mS/cm for surface and groundwaters respectively. High EC value of Kallambella groundwater accounts for its salinity. All surface waters except Honnudike and Hebbur samples contain low concentrations of these metals and are ideal for irrigation. Though the samples from Honnudike, Kadaba and Hebbur have high iron concentration, only Honnudike and Hebbur samples have exceeded the limit of 5 mg/L required for irrigation. In groundwaters the concentrations of all these heavy metals except copper are also well in permissible limits and suitable for drinking. Cu, Fe, Ni and Zn were detected in all the samples and found in the range of 0.094-0.131, 0.958-12.537, 0.020-0.036 and 0.082-1.139 mg/L respectively in surface waters and these are in the range of 0.132-0.142, 0.125-1.014, 0.028-0.036 and 0.003-0.037 mg/L in ground- waters. The elements cadmium, mercury and manganese are absent in all the samples.
