Hydrogeological Data of SW Bengal Basin

This resource contains various hydrogeological data from the SW Bengal Basin in India and Bangladesh. These data have been used in a cross border groundwater studies aiming to understand the sources of high arsenic concentration in deep (>150m) groundwater. All of the groundwater radiocarbon, d13C, 3H, arsenic data, and sediment age data indicating the source as 'this study' have been collected by a team of researchers lead by this author. Other data such as pumptest data, sediment ages, and borehole lithology have been compiled by the author from various published sources mentioned in the source column of each data, detail citation of each of those sources are provided in the source section. Borehole data showing lithology as a function of depth in 1452 locations. The radiocarbon, d13C, 3H, arsenic data are available for 33 locations along two latitudinal transects one paralleling 23.22 and the other 22.87 degree latitudes. Pump test data is available in 18 locations. There are a total of 18 sediment age data.
