Release of arsenic and iron in aquifer to groundwater under the variation of REDOX environment during bank infiltration: a case study in Huangjia groundwater source area, Northeastern China

Groundwater exploitation along a river bank can not only induce the river water infiltrating but also affect the biogeochemical reactions in the riverbank infiltration zone. Due to the differences in water chemistry in river water and groundwater, there are obvious physical, chemical and biological gradients in the riverbank infiltration zone, resulting in a series of strong and complex biogeochemical processes. In this study, Huangjia...
