摘要：The groundwater quality from Bhadravati tehsil has been assessed and results are presented in the paper.A total of 46 samples were collected out of which 23 samples represent shallow aquifers while remaining 23samples correspond to deeper aquifers. The fluoride concentration varies from 1.0 to 4.4 mg/L in phreaticaquifers and from 0.5 to 2.9 mg/L in deeper aquifers. The present investigation indicates that the fluorideconcentration is higher in shallow aquifers than in deeper aquifers. This may be ascribed to leaching offluoride in to groundwater from weathered zone. The physicochemical conditions like decomposition,dissociation as well as subsequent dissolution are also responsible for leaching of fluoride, though withlimited residence time. The inhabitants consuming the fluoride contaminated water are suffering from differenttypes of fluorosis.
