H145:
Water-Rock Interactions in Alluvial Aquifers





Session ID#: 26280

Session Description:
Alluvial aquifers are globally important, river-connected groundwater resources. The geology (often characterized by heterogeneous layers of sands and clays with abundant organic matter) of these aquifers coupled with direct connections to both surface water and deeper groundwater provides a dynamic biogeochemical environment.  Key water-rock-microbial interactions in these environments include the cycling of iron, sulfur, and carbon, which also influence the mobility of important trace elements such as arsenic.  Hence, understanding the biogeochemistry of these systems is an important global water resources problem.  Contributions to this session should advance the understanding of water-rock interactions in alluvial aquifers and may include: (1) the use of novel geochemical and isotopic tracers, (2) trace elements of health significance such as arsenic, (3) microbial transformations, and (4) the geochemistry of surface water/groundwater interactions.
