It is now documented that high concentrations of arsenic are wide-spread in Bangladesh [e.g., BGS and DPHE, 2001; Abul et al., 2001a]. Also, it is generally agreed that the arsenic is Copyright 2003 by the American Geophysical Union. The claimants are Bangladeshi villagers who drank arsenic-contaminated water from wells dug by the BGS during the 1980s and early 1990s. The number of claimants could run into thousands.

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.

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.
