Entrapment of arsenic-contaminated groundwater in point bars: Case study of Holocene Ganges River deposits, Bihar, India (abstract)

The spatial distribution of arsenic contamination in fluvial sediment of the Ganges River: Case study from Bihar, India

Shallow aquifers in the Ganges River channel belt (Bihar, India) have high and spatially variable concentrations of arsenic contamination. The arsenic is of geogenic origin. Hydrated iron-arsenic-oxide coatings on quartz and clay minerals occur in the Ganges River deposits. The arsenic is subsequently released to the groundwater in a...

Point bars as stratigraphic traps for arsenic contamination in groundwater: Case study of the Ganges River, Bihar, India (abstract)

Arsenic-contaminated groundwater causes a wide-spread, serious health risk affecting millions of people worldwide. Focus of the research is the floodplain of the Ganges River in the State of Bihar (India) where groundwater is the principal source of drinking water and irrigation, and where the levels of arsenic exceed the World Health...
