Preveously hypothesized that microbial reductive dissolution of As-containing Fe(III) oxyhydroxide (FeOOH) responsible for releasing of As in the Bengal Delta Plain (BDP) aquifers. But FeOOH is a secondary phase formed via chemical weathering of basic minerals. No one observed groundwater As concentration in shallow (i.e.<10 m depth)aquifer sediments. At that depth, reduction of FeOOH is expected to occur, since the greatest biogeochemical act...
