1998: Government launches Bangladesh Arsenic Mitigation and Water Supply Project. This includes a $32.4 million loan from the World Bank. (Recall their earlier involvement…) First half of the 00s: Projects underway in Bangladesh to prevent further exposure to arsenic. Money and resources also devoted to treating those who are sick.

BGS carried out a programme of research on the hydrogeology and hydrogeochemistry of arsenic in Bangladesh over the period 1998-2001. 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. Arsenic contamination of groundwater The BGS has been involved with research into the hydrogeology and hydrogeochemistry of arsenic in a number of high-arsenic aquifers across the world. 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 . British Geological Survey (BGS) dug hand tube-wells in Bangladesh in 1980s and early 1990s but they did not test the water for arsenic.

In Bangladesh, the groundwater As contamination problem is the worst in the world. It is alleged that BGS was negligent in not testing for arsenic when it conducted a pilot project assessing ground water in central and north-eastern Bangladesh in 1992. For many people in Bangladesh it can sometimes be a choice between death by arsenic poisoning or death by diarrhoea 110 McARTHUR ET AL.: ARSENIC IN GROUNDWATER N CN 24 N 90 W _ Figure 1.

The current paradigm within Bangladesh and West Bengal is that Fe(III) (hydr)oxides remain the dominant host of arsenic even at well depth (i.e., 30 to 50 m) within contaminated aquifers, and that organic carbon derived either from the surface or from detrital material (2, 3, 6) is stimulating reductive dissolution of the iron phases and concomitant release of arsenic.

British Geological Survey (BGS) dug hand tube-wells in Bangladesh in 1980s and early 1990s but they did not test the water for arsenic. Again BGS came back to Bangladesh in 1992 to assess the quality of the water of the tube-wells they installed but they still did not test for arsenic when groundwater arsenic contamination and its health effects in West Bengal in Bengal delta was already published in WHO Bulletin in 1988.

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,

Twenty years ago, Smith and colleagues described groundwater arsenic (As) contamination in Bangladesh as the " largest mass poisoning of a population in history ."
