ABSTRACT
Geogenic contaminants such as arsenic (As) and uranium (U) in groundwater can lead to dangerous health impacts. In this study, we have undertaken a groundwater survey across all districts of Bihar particularly in order to identify spatial distribution of trace contaminants (notably As and U) and the associated dominant geochemical conditions. Concentrations of As and U vary substantially and are strongly inversely correlated, consistent with the redox controls on As and U mobility. This work has important implications on understanding the spatial controls on As and U, remediation priorities and selection, and may be useful in informing further characterization and/or monitoring efforts.
