Uranium Transfer Phenomena in Welded Tufts

This program is a study of the conditions for uranium migration and accumulation in horizons of welded tufts (ignimbrites) and felsites of the Streltsovsky ore field in southern Siberia. The results of this study will give DOE an increased understanding of vadose-zone migration of uranium and will benefit EM programs involving contaminant radionuclide transport through fractured bedrock within the DOE weapons complex.

Characterization of Contaminated Territories, Monitoring Network Optimization, and Cost Minimization

This project will provide advanced simulation techniques to be used for decision making in the remediation of contaminated soils at DOE sites. This work is aligned to contribute to the DOE vadose zone roadmapping by providing for the characterization, assessment and remediation of contaminated portions of the vadose zone. The project is configured to provide tools to DOE to understand the data needs and a defensible approach to monitoring network optimization of long-term monitoring of environmental stewardship sites.

Uncertainty Assessment through Incorporation of Mathematical Geology in Development of Inverse Flow and Transport Models

Under this program, scientists will incorporate geostatistical methods from the evolving field of mathematical geology with inverse modeling methods that already incorporate historical observational records to better address uncertainty arising from spatial variability, assisting the groundwater modeling initiative at the Hanford Site.
