A publication entitled “The effect of Si and Al concentrations on the removal of U(VI) in the alkaline conditions created by ammonia gas”, written by Drs. Yelena Katsenovich; Leonel Lagos; DOE Fellow students; PhD Candidate, Claudia Cardona; and MS Candidate, Robert Lapierre, in collaboration with Dr. Jim Szecsody from the Pacific North National Laboratory (PNNL), was accepted for publication by the Applied Geochemistry Journal. This study evaluates changes in uranium concentrations by various pore water constituents in alkaline conditions, created in the presence of reactive gases such as NH3, to effectively mitigate uranium contamination in the vadose zone sediments. This contaminant is a potential source for groundwater pollution through slow migration of soluble and highly mobile uranium species towards the water table. This research conducted under the DOE-FIU Cooperative Agreement has provided a basis for development of thesis and dissertation topics for FIU STEM graduate students (DOE Fellows).
