Hydrogeochemical studies were carried out in and around the Zahirabad Mandal of Sangareddy district, Telangana state, India to find out the high fluoride and nitrate concentration in groundwater. 49 groundwater samples are collected from sugarcane growing areas of bore wells and dug wells in pre and post monsoon sessions and analyzed for major ions. The fluoride concentration in groundwater ranges from 0.3 to 2.7 mg/l with a mean of 1.2 mg/l in pre-monsoon and 0.1 to 1.8 mg/l with a mean 0.6 mg/l in post-monsoon. About 20.4% and 8.1% of samples in pre- and post-monsoon containing fluoride concentrations that exceed the permissible limit of 1.5 mg/l. The Nitrate concentration in groundwater ranges from 24.5 to 390.9 mg/l with a mean of 156.6 mg/l in pre-monsoon and 28 to 395 mg/l with a mean 158.1 mg/l in post-monsoon. About 89.7% of samples in pre- and post-monsoon containing nitrate concentrations that exceed the permissible limit of 45 mg/l. The results clearly show that the fluoride concentration in the study area was controlled by geogenic process, whereas the nitrate concentration in the samples was due to the excess use of fertilizers, pesticides, and organic matter.
