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, Bangladesh is currently facing a serious threat to public health, with 85 million people at risk from arsenic (As) in drinking water and in food crops. arsenic. Yet the British Geological Survey (BGS) conducted an extensive test of Bangladesh’s water supply in 1993 and pro-nounced it safe, not having tested for arsenic. That same year Ab-dul W. Khan of the Department of Public Health Engineering in Bangladesh discovered the mineral in tubewell water in the west-ern district of Nawabganj.

In Bangladesh, high arsenic concentration has been found throughout the floodplain and delta of the Ganges, Brahmaputra, and Meghan rivers, but the delta region of southern Bangladesh is the most contaminated (BGS and DPHE 2001). Arsenic present in groundwater is of natural origin and is

The comparison of 10 adjacent pairs (< 100 m or < 328 feet apart) of "very deep" (67.1 to 290 m bgs or 220 to 950 feet bgs) and shallow (< 30.5 m or < 100 feet bgs) tubewells shown in Figure 5 suggests the source of arsenic is hundreds of feet thick in many areas of Bangladesh.

understanding of the distribution of arsenic across Bangladesh's groundwater comes from the comprehensive work of the British Geological Survey (BGS) [6],

Arsenic Contamination of Groundwater in Bangladesh, Vol 2: Final groundwater arsenic concentrations in reducing Holocene aquifers (DPHE/BGS/MML, 1999; BGS and DPHE, 2001). In this paper, the first of three complementary studies in this volume, we document the spatial scale of arsenic variability for a transitional region in Araihazar upazilla, one of 460 similar administrative units in Bangladesh (Fig. 1). The British Geological Survey (BGS) conducted an investigation to identify the cause of groundwater arsenic contamination in Bangladesh. Based on their findings, they rejected the pyrite oxidation hypothesis and accepted the oxy-hydroxide reduction hypothesis.
