[email protected] Abstract 25 The spreading of water-related diseases in Central India related to high concentrations of fluoride ion (F-) is a cause of major concern. In this work, the hydrochemistry of the aquifers related to Seonath River, in Rajnandgaon district, Chhattisgarh state, has been studied, focusing on the presence and sources of F-. Hydrochemical parameters were analyzed in the post-monsoon season in 160 wells located in nine tehsils, finding F- concentrations ranging from 0.6 to 18.5 mg·L-1.
