文摘

Groundwater As is predominantly regulated by active As forms in sediments. The scale of geochemical factors is vital in better understanding relative contribution to groundwater As concentrations. Groundwater flushing decreases As concentration at the multi-basin scale. Redox conditions are the key factor controlling groundwater As at the scale of contaminated sites.
