Abstract [en]

A comparative hydrogeochemical study was carried out in West Bengal covering three physiographic settings of deltaic floodplains to demonstrate the control of geogenic and anthropogenic influences on groundwater arsenic (As) mobilization. The low redox potential (Eh = -185 to -86 mV) and the presence of low sulfate (SO 4 2-) and high Dissolved Organic Carbon (DOC), phosphate (PO 4 3-) and bicarbonate) (HCO 3 -) concentrations in groundwater signifies microbially mediated redox processes controlling As release in the aquifer. The release of As is influenced by both geogenic (i.e. geomorphology and/or landform features) and anthropogenic (i.e. unsewered sanitation and domestic wastes) factors.
