Hydrogeochemical characterization and potential geogenic source of fluoride contamination in Gariaband district of southern Chhattisgarh, India.

Fluoride contamination of groundwater exerts serious health concerns in developing countries like India, where surface water resources in general are not considered for domestic consumption. The present investigation attempts to evaluate the groundwater quality in terms of fluoride contamination in Deobhog and adjoining areas in Gariaband district, Chhattisgarh. A total of 68 groundwater samples were collected both in the pre- and post-monsoon period and analyzed for different physicochemical parameters like Temperature, pH, EC, TDS, Na, K, Ca, Mg, HCO, NO, Cl, SO, and F.
