Okunskap om geologin i Bangladesh håller på att leda till en mycket stor förgiftningskatastrof. Ett stort antal invånare från Bangladesh har nu gått samman för att stämma BGS för att To combat the Arsenic catastrophe.

understanding of the distribution of arsenic across Bangladesh's groundwater comes from the comprehensive work of the British Geological Survey (BGS) [6],

In Bangladesh, high arsenic concentration has been found throughout the floodplain and delta of the Ganges, Brahmaputra, and Meghan rivers, but the delta region of southern Bangladesh is the most contaminated (BGS and DPHE 2001). Arsenic present in groundwater is of natural origin and is 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.

Dhaka, 21 Jun 2007 Recently, the Bangladesh Arsenic Mitigation Water Supply Project been reported by other studies (BGS and DPHE 2001; Chowdhury 2004). It is estimated that approximately 27% of the wells are contaminated with levels above 50ppb, the current drinking water standard for arsenic in Bangladesh ( av T Karlsson · 2005 — Bangladesh Arsenic Mitigation Water Supply.

Of the 3,534 samples analyzed in the BGS/DPHE study, only 9 percent were from deep tube wells (> 150 m) and the rest were from shallow wells. Of the shallow tainability of the low-arsenic aquifers at Matlab, in south-eastern Bangladesh, one of the BGS and DPHE 2001, Smedley and Kinniburgh 2002, van Geen et al.

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.

Arsenic contamination of six districts in West Bengal, India: the biggest arsenic calamity in the World. Analyst, 199, 168-170. But neither of these BGS articles mentions arsenic although, according to experts, the data contains many very clear chemical pointers to its presence (high phosphorus and iron, highish bicarbonate) . In Bangladesh, high arsenic concentration has been found throughout the floodplain and delta of the Ganges, Brahmaputra, and Meghan rivers, but the delta region of southern Bangladesh is the most contaminated (BGS and DPHE 2001).

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.

21 Jun 2007 Recently, the Bangladesh Arsenic Mitigation Water Supply Project been reported by other studies (BGS and DPHE 2001; Chowdhury 2004).

In this context, Bangladeshi villagers went to British court [10] blaming that BGS was responsible for their sufferings from arsenic toxicity. A BGS survey of Chapai Nawabganj in early 1997 confirmed the extremely high concentrations of arsenic – up to 2.4 mg/l – and low concentrations of sulphate. University College London in collaboration with Dhaka University, BWDB and MML carried out the first systematic geologically based investigation of the occurrence of arsenic in Bangladesh. Sulfate and arsenic concentrations measured at our study site (4) (circular and square data points), and mean, median, and 90th-percentile of the shallowest 2,848 samples from the country-wide British Geologic Survey report (ref.

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.

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. 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. (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].
