Enrichment of arsenic (As) and other geogenic toxins (e.g. Co, Cr, F, Hg, Mn, Se, U) has resulted in severe pollution of potable surface and groundwater, soils and plants in many parts of the world, leading to severe environmental crisis on a global-scale. We are one of the global leaders in developing and executing inter-disciplinary research in understanding the occurrence and mobility of As and other toxic metals in water systems. We study the hydrodynamic, hydrogeochemical and biogeochemical controls on the distribution, contaminant fate and kinetics in natural and anthropogenically-induced groundwater and aquifer systems across the globe and up to laboratory-scale experiments. We lead most of the geoscientific research on As in India and regularly collaborate with other major As research groups at KTH (Sweden), Dhaka University (Bangladesh), UCL (UK), Columbia University and MIT (USA)
