Abstract
Surficial deposits of the Midnapur coastal zone are laterally discontinuous layers or lenses of modern marine clays, silts, and sands; older Quaternary and Tertiary sediments are presumably present at depth. Two major belts of sand dunes and an intervening smaller belt parallel the present shoreline. Data from wells show that a shallow water-table aquifer (at depths of 20-50 feet) yields small to moderate quantities of potable calcium bicarbonate-type water in areas where the sand cover is sufficiently thick, and that a deep artesian aquifer (440-580 feet) yields fresh water of sodium bicarbonate type in most places. At greater depth, the water is saline and probably of connate origin; water of variable salinity due to mixing of meteoric and connate waters is encountered at intermediate depths.
