Particle size, Associations, and Crystallinity of Bioreduced Uranium phases

Lead Institution
Stanford University
Principal Investigator
Scott Fendorf
Project type
Exploratory Research
Due to mining and nuclear-production activities, uranium is an environmental contaminant of great concern; within surface and subsurface environments, uranium predominates in either the (VI) or (IV)…

Impact of natural organic matter on U speciation and mobility in groundwater

Lead Institution
Environmental Molecular Sciences Laboratory
Principal Investigator
John Bargar
Project type
Exploratory Research
Uranium (U) contamination of aquifers is a persistent problem at DOE legacy ore processing sites and, contrary to initial predictions, many plumes are not attenuating with natural groundwater…

The Role of Anaerobic Microsites in Soil Carbon Storage

Lead Institution
Stanford University
Principal Investigator
Scott Fendorf
Project type
Large-Scale EMSL Research
The overarching goal of this project is to quantitatively place the importance of metabolic constraints in anaerobic microsites on the rate of soil organic matter (OM) oxidation, and thus advance our…

Mechanisms of Fe Biomineralization Induced By Dissimilatory Iron Reduction

Lead Institution
Woods Hole Oceanographic Institution
Principal Investigator
Colleen Hansel
Project type
Exploratory Research
Iron minerals are ubiquitous in nature and play a critical role in the geochemical cycling of trace elements. In particular, iron oxides serve as potent sorbents and repositories for nutrients and…

Microscopic Mass Transfer of U and Tc in Subsurface Sediments

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Chongxuan Liu
Project type
Exploratory Research
This project will investigate microscopic mass transfer process and its influence on and coupling with geochemical and biogeochemical reactions in subsurface sediments. The research will focus on…
