The water survey at the centre of the controversy was carried out by the British Geological Society (BGS), a part of NERC, in Bangladesh in 1992. According to BGS, arsenic was not widely known to be present in the types of alluvial plains found in the region until an international meeting was called in Kolkata in 1995, three years after their

But neither of these BGS articles mentions arsenic although, according to experts, the data contains many very clear chemical pointers to its presence (high phosphorus and iron, highish bicarbonate) . 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).

Twenty years ago, Smith and colleagues described groundwater arsenic (As) contamination in Bangladesh as the "largest mass poisoning of a population in history." An estimated 60 million people were unknowingly drinking groundwater containing dangerous concentrations of naturally occurring As. Today, despite a much-improved well water testing effort, an estimated 30–35 million are still 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.
