Supports a research program and a national scientific user facility: Environmental Molecular Sciences Laboratory (EMSL) $39M Environmental Remediation Sciences Program $47.5M The William R. Wiley Environmental Molecular Sciences Laboratory (EMSL), a U.S. Department of Energy national scientific user facility located at Pacific Northwest National Laboratory (PNNL) in Richland, Washington provides integrated experimental and computational resources for discovery and technological innovation in the environmental molecular sciences to support the needs of DOE and the nation.

5. ERSD Mission …Advance the fundamental science leading to solutions to currently intractable environmental problems or to break-through strategies for remediation of the DOE sites and other DOE environmental and energy missions. Bioimmobilization of chromium from groundwater at the Hanford site

6. 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

7. 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

8. 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

9. 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 http://www.sc.doe.gov/ober/ERSD/Strategic_plan_cover_letter.html

10. 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 relevantcontaminant 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
