Office of Science U.S. Department of Energy In the last 6 months……  Personnel  Teresa Fryberger (Division Director) continues on detail to OSTP  David Lesmes hired (Program Manager, geophysics)  Mike Kuperberg hired (Acting Division Director, toxicology)  Two research calls currently in process  Follow-on Review of EMSL by BERAC  Termination of high-level waste research due to FY 2007 budget reductions

Office of Science U.S. Department of Energy Environmental Remediation Sciences Program  FY 2006 Budget consolidated two former programs into a single research program  Environment Remediation Sciences Program (ERSP)  Maintains interest in processes that control contaminant mobility in subsurface  Focus on DOE-relevant metals and radionuclides

Office of Science U.S. Department of Energy Performance Monitoring  Long-term measure  “By 2015, provide sufficient scientific understanding to allow a significant fraction of DOE sites to incorporate coupled biological, chemical and physical processes into decision making for environmental remediation and long-term stewardship”  Annual Target  FY 2006: Develop predictive model for contaminant transport that incorporates complex biology, hydrology, and chemistry of the subsurface. Validate model through field tests  Quarterly Milestones

Office of Science U.S. Department of Energy ERSP Strategic Plan Research Goals  Develop an improved understanding of the processes governing the fate and transport of contaminants to predict and control environmental remediation and facilitate stewardship of DOE sites  Fundamental, molecular-level understanding of observed phenomena  Coupled biological, chemical and hydrogeologic processes at field relevant spatial scales  Conceptual models for realistic process and parameter upscaling in field environments  Explore new options and concepts for remediation of subsurface systems  Microbial metabolic processes that control contaminant mobility  Key redox/complexation reactions and degradation pathways  Form and stability of immobilized contaminants  Genomics:GTL tools for genomics and proteomics  Provide the scientific foundation for new measurement and monitoring tools to better understand and manage contaminant transport  Changes in microbial community composition and metabolic potential  Measuring biogeochemical and hydrologic responses  Assessing chemical speciation in sediments and waters

Office of Science U.S. Department of Energy Current Solicitations  ER06-12 Environmental Remediation Sciences Program ($20M) ~180 proposals received in 5 research elements  hypothesis-driven research to define biologically-mediated and/or hydrogeochemical processes influencing the form and mobility of DOE contaminants  address the applicability of the proposed research to DOE relevant contaminant transport processes occurring in the field  ER06-16 Integrated Field-Scale Subsurface Research Challenge ($6M) Expecting five full proposals (due July 27)  establish field research site(s) where integrated science teams manage and conduct field-site research over a five year period.  hypothesis-based field research on key processes influencing the subsurface transport, immobilization or remobilization of metal and radionuclide contaminants at DOE sites  provide samples and short-term access to other ERSD investigators
