Hydrogeochemical investigations have been carried out in parts of Karimnagar district of Telangana to study the distribution of fluoride in groundwater of Gangadhara area. Eighty five groundwater samples were analyzed in January, 2013 (post-monsoon) and also in June, 2013 (pre-monsoon) for pH, Ec and Fluoride. It is observed that the groundwater in both the seasons is alkaline in nature. 39% of groundwater in post- monsoon and 23.52% of groundwater in pre-monsoon has higher concentration of Electrical conductivity than the prescribed limit. The higher values indicate that ionic concentrations are more in the groundwater. Nearly 65% of groundwater has more than the permissible limits of fluoride prescribed for drinking purpose in both post-monsoon and pre-monsoon seasons in the study area.
