Bangladesh: DPHE/BGS National Hydrochemical Survey. The aims of the survey were to: make maps showing the regional distribution of arsenic and other elements in Bangladesh groundwaters. provide estimates of the percentage of wells exceeding various limits for arsenic and other elements.

Dhaka University, Bangladesh Since arsenic in groundwater was recognized as a potential threat to secondary sources (DPHE/BGS, 1999; DCH, 1999).

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. BGS Map of arsenic contamination in wells (1998) Arsenic contamination in Bangladesh. More Maps of the distribution of arsenic, and other elements in Bangladesh groundwater are shown in the power point file : of a talk by Peter Ravenscroft The BGS statement argues that, at this time, arsenic was not a recognized contaminant of groundwater in Bangladesh or regions with similar flood-plain geology: "There was no indication in the 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 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).

This work has been funded by a number of organisations, including the UK government's Department for International Development, NERC, World Bank, Danida and Unicef.
