|Abstract:||Arsenic content in groundwater and surface waters from Murshidabad district of West Bengal varies from 0.05 to 3.7 mg/l. Arsenic was scavenged by Fe(III) minerals (primarily as iron oxyhydroxides), and to a lesser extent by Mn(IV) phases and is released into the groundwater due to lowering of the redox conditions in the aquifer system. Similarities in some trace element ratios of the Early Cretaceous age Rajmahal volcanic rocks with those of the arsenic contaminated groundwaters in this areas designates these rocks as a possible primary source for the arsenic contamination.|
