Sediment Color Tool: Empowering local drillers for safe water
The arsenic in Bangladesh’s shallow aquifers is naturally occurring, the result of a confluence of interlinking factors. Particles of iron oxide with arsenic chemically bound to them are carried into Bangladesh from the Himalayan Mountains by the fast-moving Ganges and Brahmaputra rivers. Currently, about 1/3 of the tube wells in Bangladesh pump up water exceeding the arsenic standard of 50 ppb (parts per billion). In some areas arsenic levels are 2000 ppb, 40 times over the acceptable level for drinking. Most of the wells register 200 to 400 ppb of arsenic. Inorganic arsenic is naturally present at high levels in the groundwater of a number of countries, including Argentina, Bangladesh, Chile, China, India, Mexico, and the United States of America.
But farmers are also pumping water from those deep aquifers, threatening the water supply and In Bangladesh, 27 % of shallow tube-wells have been shown to have high levels of arsenic (above 0.05mg/l). It has been estimated that 35 - 77 million of the total population of 125 million of Bangladesh are at risk of drinking contaminated water (WHO bulletin, volume 78, page 1096) Arsenic contamination of groundwaters was first detected in Bangladesh in 1993 by the DPHE in Chapai Nawabganj in the far west of Bangladesh in a region adjacent to an area of West Bengal which had been found to be extensively contaminated in 1988. More recently, the Bangladesh Arsenic Mitigation Water Supply Project ( BAMWSP) carried out a very detailed screening of tube wells and a survey of arsenicosis 1 Feb 2021 Years later, however, these tube wells were discovered to have been contaminated with arsenic in almost every Bangladeshi district.
