Estimating arsenic concentrations in Bihar (India), a geostatistical approach using DEM data

Bihar is a densely populated area located in the Middle Ganga Plain (MGP) in India. The Ganges' sinuous nature in the MGP created a vast amount of point bar structures within the floodplain. In 2003 it was discovered that high arsenic concentrations are present in the shallow groundwater aquifers, especially in the elevated point bars. According...
