Organic Carbon Migration in Aquatic Environments


Organic matter in aqueous systems often controls geochemical processes by acting as proton donors/acceptors and pH buffers, by affecting the transport and degradation of pollutants, and by participating in mineral dissolution/ precipitation reactions. To more clearly understand the dynamics of carbon cycling and chemical transport, better definition of geochemical processes as they apply to dissolved organic carbon is required. In particular, understanding the chemical mechanisms controlling the fate and transport of both naturally occurring and anthropogenic compounds in ground water and sediments is needed. Objectives are to determine the role of chemical processes associated with bulk dissolved organic carbon (DOC) on the transport of both naturally occurring and anthropogenic compounds -- these processes include sorption, partitioning, cosolute enhanced transport and colloidal interaction; to demonstrate that nonvolatile organic acids resulting from the degradation of organic matter are interactive components of aquatic environments; and to demonstrate that DOC interactions within a given environment control hydrophobic constituent transport in aqueous systems.
