Based on their findings, they rejected the pyrite oxidation hypothesis and accepted the oxy-hydroxide reduction hypothesis. 2 Bangladesh University of Engineering and Technology, Dhaka, Bangladesh 3 University of British Columbia, BC, Canada 4 Tufts University Abstract: Although arsenic contaminated groundwater in Bangladesh is a serious health issue, little is known about the complex transient patterns of groundwater flow that flush solutes from Engineering (DPHE), Bangladesh and British Geological Survey (BGS), United Kingdom conducted a study in 1998-1999 and identified 61 district of Bangladesh as arsenic affected out of total 64. This the first hypothesis, groundwater arsenic contamination is human-made, which has a relationship with excessive groundwater withdrawal.

with arsenic for sorption sites on the iron oxides ( Creger and Peryea, 1994). However, BGS and MacDonald (2000) suspect that most of the phosphate is derived from natural geological sources. The groundwater arsenic problem in Bangladesh arises because of an unfortunate combination of three factors, namely,

(cited 6 December 2001), Groundwater Studies of Arsenic Contamination in Bangladesh. The levels of arsenic in tubewell water as shown in BGS and DPHE study are also high in the central region (BGS and DPHE, 2001). The area of high arsenic concentration very well fit with the areas of Bangladesh submerged by flood (Ahmed, 2000).
