Mahanadi delta occurs on the east coast of India, in the state of Orissa. Groundwater is a major source of fresh water in the are., The permeable sand and gravel layers in the unconsolidated sediments form the potential aquifers, having a cumulative thickness of 15-65 m. Groundwater occurs under both confined and unconfined conditions. The depth to water table varies from less than 2 m to 4 m below ground level. The well yields vary from less than 35 m3/hr in the basin marginal areas in the west to more than 270m3/hr in the coastal plains in the east. K and S values of the deeper aquifers are in the range of 5-330 m/day and 1.75×10-2-8.81×10-6respectively. But the aquifers are beset with salinity hazards. The saline and fresh water profile is non-uniform with freshwater overlying/underlying or alternating with saline zones, or with saline water at all depths. However, the ground water quality is in general fresh (EC<1600 μS/cm) and suitable for all uses, except in areas having high salinity, and in localized pockets showing high concentration of iron, fluoride, nitrate and sulphate being injurious to health. The annual groundwater recharge is of the order of 35 1069 HAM, with gross draft of 39688 HAM. The paper presents the complex hydrogeological set-up in the delta and outlines groundwater development potentials.Keywords

A detailed investigation of the 'rock melt extrusion', reported about three years back in this journal from Puruliya district, suggests it to be a surface phenomenon. The heat generated by burning of the torn out overhead 11 KV electric lines melted locally the fragmentary amphibolite pieces as well as the enclosing deep brown soil to the south of Jabjabigora. Petrographic, physical and geochemicaI data suggest that both the deep brown soil and amphibolite fragments underwent possibly complete melting on the surface, the former at a temperature a little above 1100°C and the latter at above 1350° to 1360°C.Full Text
