摘要：
The distribution pattern of arsenic contamination in the Ganges delta aquifer is patchy, and one "hotspot" has been investigated in detail. A contaminated plume originating from a paleo-meander is moving along water flow lines, with an arsenic distribution of 42% As(III) and 58% As(V) in average. A ID reactive transport model of the plume shows a much faster move of the plume once competion between bicarbonate, phosphate, ferrous iron and arsenic ions are taken into account.
