Watershed Controls on Uranium Concentrations Tied into Natural Organic Matter and Iron Interactions in Streambeds and Wetlands
The focus of our project is on understanding natural organic matter (NOM) properties and their influence on U remobilization/immobilization, considering the important roles of watersheds hydrology and microbial dynamics. Laboratory and analytical techniques assessed these dynamic processes at ambient U and OM concentrations, in order to find favorable environmental settings that make the wetland, stream sediment, and flocs an organic C and/or U sink or source.
