Groundwater samples were collected in parts of Kesamudram mandal, Mahabubabad district, Telangana State, India for two seasons (pre-monsoon and post-monsoon) and analyzed for chemical parameters with respect to fluoride. The fluoride concentration ranges from 0.52 to 3.40 mg/l and 0.08 to 2.60 mg/l during pre-monsoon (PRM) and post-monsoon (POM) seasons respectively. Results showed that water samples were contaminated with presence of fluoride ion. High fluoride concentration recorded during PRM 33% and POM 29% when compared with World Health Organization tolerance limit of 1.5 mg/l. Hydrogeochemical facies distribution indicates water-rock interaction resulted in occurrence of high fluoride concentration in groundwater. An analytical result plotted on Gibb’s diagram indicates rock and evaporation dominance. Principal component analysis indicates hydro-geochemical processes like weathering, ion exchange, and anthropogenic activities contribute to groundwater chemistry.
