Abstract:This study deals with groundwater quality and As mobilization behavior in the shallow (up to ∼50 m) and deeper (below ∼100 m) aquifer levels in Bengal Delta Plain. The groundwaters from shallow aquifer levels are enriched with redox sensitive species, HCO3−, DOC, PO4−3 and NH4+, whereas the deeper aquifer level contains relatively low As, PO4−3, DOC and NH4+, low to very low Fe (II), and high HCO3−. In the shallow aquifer levels, As release to the groundwater is a combination of Fe reduction, local recharge and ion-exchange processes. However, in the deeper aquifer As mobilization is mostly governed by carbonate dissolution and chloride exchange processes.
