Description:

Managed aquifer recharge (MAR) has a potential for addressing deficits in water supplies worldwide. It is also widely used for preventing saltwater intrusion, maintaining the groundwater table, and augmenting ecological stream flows among many beneficial environmental applications. However, field MAR sites have experienced arsenic mobilization from aquifer formation due to the induced changes in groundwater chemistry. To address the environmental concern, it is crucial to understand holistically the potential sources and sinks impacting arsenic remobilization. This critical review outlines important mineral-water interactions that can occur at a MAR site. Detailed information on minerals of concern, physiochemical processes for arsenic mobilization or attenuation, and the potential impact of microbial activity on these processes is provided. Finally, this paper offers connections between interfacial reactions and reactive transport modeling, which allows for scaling up the understanding and provides future frontiers and grand challenges in safer and more sustainable MAR operations.
