1. 6. Aqueous Phase Geochemical Characterization and Delineation of Low Arsenic Aquifers in Matlab Upazila, SE Bangladesh.

   University essay from KTH/Miljögeokemi och ekoteknik

   Author : Rajib Hassan Mozumder; [2011]
   Keywords : arsenic; Bangladesh; groundwater; mitigation; color tool; aquifer; highstand; lowstand;

   Abstract : The fact that the former highstand whitish sediments of Plio-Pleistocene and lowstand off-white/red sediments of Late Pleistocene containing low As concentrations in the Bengal basin forms the premise for developing a color tool by the ‘Sustainable Arsenic Mitigation Project’ (SASMIT) to guide the local drillers of Matlab, SE Bangladesh, so that they can target low As aquifers. Groundwater samples collected from the black group of sediments representing a highly reducing environment contains very high concentrations of As, Fe2+ , NH4+, PO43-, HCO3–, and DOC and very low SO42- and Mn2+ concentrations; and vice-versa for the red/offwhite/white group of sediments, thus representing a less reducing condition.
