Influence of geochemical morphological and hydrological factors on groundwater arsenic distribution in a complex terrain

Abstract

Contamination of groundwater by Arsenic As a known carcinogen is a major drinking water concern affecting millions globally including South and South East Asia Often associated with iron III hydroxides within soils and sediments arsenic gets released into groundwater through multiple hydrogeochemical processes Nearly three decades of research has led to our understanding that reductive dissolution of Fe III oxyhydroxides is the primary mechanism of arsenic release into aquifers Yet
