Variations in the redox state of As and Fe measured by X-ray absorption spectroscopy in aquifers of Bangladesh and their effect on As adsorption


, : Variations in the redox state of As and Fe measured by X-ray absorption spectroscopy in aquifers of Bangladesh and their effect on As adsorption. Applied Geochemistry: 1, 34-47

Groundwater enrichment with naturally occurring As is a very serious problem. In Bangladesh, many thousands of people are drinking such groundwater. Household well waters generally show a large variation of concentration of As even within a small village. This variation creates difficulty in the design of mitigation strategies. It was hypothesized that the concentration of As in each well is controlled by an adsorption-desorption equilibrium between sediment and groundwater.
