The groundwater quality from the watersheds PGK1, PGK3 and PGK4, Yavatmal District (Maharashtra), Central India, has been assessed and results are presented in the paper. Fifty samples collected from deeper aquifers have been analysed for various parameters like pH, EC, TDS, Ca++, Mg++, Na+, K+, HCO3-, CO3-2, Cl-, SO4-2, and F-. The interrelationship between F- with pH, Na+, SO4-2, and Cl- has resulted into positive correlation, while inverse relationship is noted for Ca++ and HCO3-. In the area of study, the Fcontent ranges from 0.2 to 15.6 mg/L, and 64% of groundwater samples from deeper aquifer have Fconcentration more than 1.0 mg/L. The higher concentration of F- in Neoproterozoic limestones has been ascribed to the presence of fluoride bearing minerals like fluorite and apatite. In such limestones of chemical origin, co-precipitation of CaF2 and CaCO3 is the major process which controls the fluorine distribution in the rocks. The leaching of F- containing minerals from the weathered zone to deeper depth has contributed the high F- concentration in basaltic aquifers. Amongst the analysed samples, 58% of groundwater is suitable for irrigation.Keywords

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 23 samples correspond to deeper aquifers. The fluoride concentration varies from 1.0 to 4.4 mg/L in phreatic aquifers and from 0.5 to 2.9 mg/L in deeper aquifers. The present investigation indicates that the fluoride concentration is higher in shallow aquifers than in deeper aquifers. This may be ascribed to leaching of fluoride 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 with limited residence time. The inhabitants consuming the fluoride contaminated water are suffering from different types of fluorosis.Keywords
