Arsenic Contamination of Groundwater in Bangladesh, Vol 2: Final groundwater arsenic concentrations in reducing Holocene aquifers (DPHE/BGS/MML, 1999; BGS and DPHE, 2001). 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). The British Geological Survey (BGS) conducted an investigation to identify the cause of groundwater arsenic contamination in Bangladesh. Based on their findings, they rejected the pyrite oxidation hypothesis and accepted the oxy-hydroxide reduction hypothesis.

It has been trying, in part, to 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 study. The British Court of Appeal has rejected a claim that British geologists were to blame for failing to detect arsenic in Bangladesh. Using Data From the Arsenic Problem in Bangladesh (Martin Stute, Barnard College). martins@ldeo.columbia.edu Summary: The Arsenic in drinking water issue in Bangladesh presents a unique opportunity to motivate studying hydrogeology in context of water resources issues in the developing world.

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).

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. If the demographics of Bangladesh as reported by the BBS and arsenic concentrations as reported by the BGS and DPHE continue into the future, the health effects of dissolved arsenic in well water will be severe: prevalences of about 2 million cases of arsenicosis and 125,000 cases of skin cancers, and incidences of several thousand deaths from internal cancers per year.

(DPHE) tested wells in western Bangladesh after ground-water arsenic was discovered in West Bengal. 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.
