Arsenic attenuation by oxidized aquifer sediments in Bangladesh

Verified

Kenneth G. Stollenwerk, George N. Breit, Alan H. Welch, James C. Yount et al.

Journal: The Science of The Total EnvironmentYear: 2007Citations: 242

Recognition of arsenic (As) contamination of shallow fluvio-deltaic aquifers in the Bengal Basin has resulted in increasing exploitation of groundwater from deeper aquifers that generally contain low concentrations of dissolved As. Pumping-induced infiltration of high-As groundwater could eventually...
