Developing an environmentally appropriate, socially acceptable and gender-sensitive technology for safe-water supply to households in arsenic affected areas in rural Bangladesh

In Bangladesh about 95 percent of the people depend on tube-well water drawn from alluvial aquifers underlying the Ganges and Brahmaputra delta. However, a large proportion of the groundwater from the shallow tube wells is contaminated with high concentrations of naturally occurring arsenic (As). Options to abate this problem are extraction from deeper aquifers, return to the use of surface water and arsenic removal systems at household level. The last option is most feasible on a short term basis. Although a number of household-level removal systems have been developed – such as those based on adsorption, chemical oxidation in combination with adsorption, ion exchange, chemical oxidation and coagulation – the non-technical aspects, relevant to the introduction and safe application of the appliance, have been largely glossed over. For this reason the implementation of these systems is as yet not very successful. There is a knowledge gap between what we know of the technical features of these technologies and the lack of knowledge about the suitability of the technologies for rural
households and rural women in a specific socio-cultural context. This study intends to address this knowledge gap. Therefore, the overall goal of the proposed study is to contribute to finding feasible, socially appropriate and gender-sensitive household-level technological solutions to the problem of arsenic groundwater contamination in rural Bangladesh. To achieve this goal, an innovative interdisciplinary study design was used. [authors abstract]

Abstract

In Bangladesh about 95 percent of the people depend on tube-well water drawn from alluvial aquifers underlying the Ganges and Brahmaputra delta. However, a large proportion of the groundwater from the shallow tube wells is contaminated with high concentrations of naturally occurring arsenic (As). Options to abate this problem are extraction from deeper aquifers, return to the use of surface water and arsenic removal systems at household level. The last option is most feasible on a short term basis. Although a number of household-level removal systems have been developed – such as those based on adsorption, chemical oxidation in combination with adsorption, ion exchange, chemical oxidation and coagulation – the non-technical aspects, relevant to the introduction and safe application of the appliance, have been largely glossed over. For this reason the implementation of these systems is as yet not very successful. There is a knowledge gap between what we know of the technical features of these technologies and the lack of knowledge about the suitability of the technologies for rural
households and rural women in a specific socio-cultural context. This study intends to address this knowledge gap. Therefore, the overall goal of the proposed study is to contribute to finding feasible, socially appropriate and gender-sensitive household-level technological solutions to the problem of arsenic groundwater contamination in rural Bangladesh. To achieve this goal, an innovative interdisciplinary study design was used. [authors abstract]
