Sediment and groundwater profiles were compared in two villages of Bangladesh to
understand the geochemical and hydrogeological factors that regulate dissolved As …

Samples were collected every 2–4 weeks from a set of 37 monitoring wells over a period of
2–3 years in Araihazar, Bangladesh, to evaluate the temporal variability of groundwater …

Studies within the As-affected Bengal Basin have indicated that low-As groundwater can be
found in a variety of geological and geomorphological settings. The hydrogeological …

Background High salinity and arsenic (As) concentrations in groundwater are widespread
problems in the tidal deltaplain of southwest Bangladesh. To identify the sources of …

Background The origin of the spatial variability of dissolved As concentrations in shallow
aquifers of the Bengal Basin remains poorly understood. To address this, we compare here …

Abstract Across South Asia, millions of villagers have reduced their exposure to high‐
arsenic (As) groundwater by switching to low‐As wells. Isotopic tracers and flow modeling …

Dissolved major ions and important heavy metals including total arsenic and iron were
measured in groundwater from shallow (25–33 m) and deep (191–318 m) tube-wells in …

A comparative study of arsenic enrichment in the Bengal Delta (BD) was carried out in three
alluvial aquifers in south-central Bangladesh. Investigated sites included Sonargaon in …

Arsenic in the groundwater of Bangladesh is a serious natural calamity and a public health
hazard. Most groundwater from the shallow alluvial aquifers (< 150 m), particularly in the …

Arsenic contaminates groundwater across much of southern, central and eastern
Bangladesh. Groundwater from the Holocene alluvium of the Ganges, Brahmaputra and …
