In the present study, the groundwater quality in Rajnandgaon District of Chhattisgarh State in Central India is assessed. A total of 90 Groundwater (GW) samples are collected during Monsoon (M) and Non-Monsoon (NM) periods from various existing bore wells and tube wells in the study area, and they were analyzed for estimating the Fluoride (F −) concentration in the existing GW with a special emphasis. The Physico-Chemical characteristics, in addition to the concentration of major Anions and Cations in the existing GW were also assessed. The results reveal that the fluoride concentrations in the existing GW in Rajnandgaon District is ranging >0.50 to <5.07 p.p.m. Most of the places in the study area are affected by high fluoride concentrations, and is evident from the 23% of total samples collected showing >1.5 p.p.m. of fluoride concentration, which is a maximum permissible limit recently suggested by Bureau of Indian Standard (BIS) (BIS: 10500, 2010). It is also seen that the fluoride is having poorly and burly positive correlations with calcium and sodium, respectively. Further, the study also includes the verification of suitability of GW for drinking in the study area.
