RESUMO
Two formations, Barakar and Talchir belonging to Lower Gondwana sequence form aquifer in Durgapur area. Groundwater of these formations sampled for boron investigation in two seasons, Post-monsoon and Pre-monsoon. The water quality differed from aquifer to aquifer, mainly with respect to conductivity and B contents. Talchir groundwater shows greater conductivity and greater B content than Barakar groundwater. The maximum concentration of B was found in Talchir pre-monsoon groundwater. Greater B in Talchir groundwater is attributed to glacio-marine environment of sediment deposition. The correlation of B with major ions also varies. It shows positive correlation with conductivity, Na, HCO3 and SO4 in Barakar groundwater and with SO4 in Talchir groundwater. Seasonal variation in concentration of B exists but not appreciable.
