Groundwater samples were collected in Chevela mandal, Ranga Reddy district, Telangana State, India for two seasons (pre-monsoon and post-monsoon) and analyzed for chemical parameters with respect to fluoride and nitrate. Spatial distribution of nitrate and fluoride high values is observed from the northern, southern, central and south-western parts of the region. In terms of NO3- about 43% and 42% and F- 29% and 26% of the groundwater samples are non-acceptable limits of nitrate is 45 mg/l and fluoride is 1.5 mg/l during pre and post-monsoon seasons respectively. 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.
