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).

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.

Distribution of Arsenic (BGS and DHPE, 2001) The project 'Groundwater Studies for Arsenic Contamination in Bangladesh' was a reconnaissance investigation of the arsenic problem, carried out over the period 1998 to 2001. Its remit was to collate available data and conduct new groundwater surveys.

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.

The worst arsenic problem in the world is clearly in BANGLADESH. Mott Macdonald Ltd., working on behalf of DPHE and the UK Geological Survey (BGS) in summer 1998 collected all available data and surveyed another "representative sample" (although not formally a random sample) of 1,800 wells.

This the first hypothesis, groundwater arsenic contamination is human-made, which has a relationship with excessive groundwater withdrawal. On the other hand, according to the second one, the contamination is natural. The British Geological Survey (BGS) conducted an investigation to identify the cause of groundwater arsenic contamination in Bangladesh. 5 Nov 2010 Arsenic contamination of groundwater in Bangladesh Additional Keywords: GroundwaterBGS, Groundwater.
