Hydrological and geochemical constraints on the mechanism of formation of arsenic contaminated groundwater in Sonargaon, Bangladesh
T Itai, H Masuda, AA Seddique, M Mitamura… - Applied …, 2008 - Elsevier
The geochemical characteristics and hydrological constraints of high As groundwater in
Sonargaon, in mid-eastern Bangladesh were investigated in order to ascertain the
mechanism of As release into the groundwaters from host sediments in the Ganges–
Brahmaputra delta. Samples of groundwater were collected from ca. 230 tube wells in both
the rainy and dry seasons. Similar to previous studies, high As groundwater was found in the
Holocene unconfined aquifer but not in the Pleistocene aquifer. Groundwaters in the …
