The Hanford Legacy
Manager of Environmental Health and Remediation
Energy and Environment Directorate
TCS Building 240
Founded as part of the Manhattan Project, the Hanford Site has played a vital role in the Nation's nuclear weapons and energy production missions. Today, Hanford poses one of the most technically, financially, and socioeconomically difficult cleanup challenges in the world. With over 200,000 m3 of tank waste, 700 m3 of nuclear materials, 1 billion m3 of groundwater and soil contaminated with long‑lived transuranic radionuclides, and 5.5 million m3 of contaminated facilities requiring decommissioning and disposal, the Hanford Site presents some of the most extensive and complex challenges ever faced within the DOE complex. With an approximate 50+ year mission and a remaining estimated cost of more than $100 billion, significant advances in science and engineering are required to address both short- and long-term challenges to achieve mission objectives.
This presentation will provide a brief history and overview of current and future Hanford remediation and waste treatment efforts, and highlight unique scientific and technical challenges therein.
Dr. Wellman is a staff scientist, program manager, and the manager of the Environmental Health and Remediation (EH&R) market sector at Pacific Northwest National Laboratory. Dr. Wellman holds a Ph.D. in chemistry from Washington State University. Her scientific expertise is in understanding and predicting contaminant transport pathways and kinetics, aqueous and mineral surface geochemistry, and reaction kinetics for environmental remediation. She builds upon this fundamental understanding to develop and implement systems-based approaches for characterizing, monitoring, and remediating contaminated groundwater and soil at sites throughout the Department of Energy, as well as internationally, supporting site contractors and site owners.
In 2009, Dr. Wellman served as the Chief Scientist for the Office of Technology Innovation and Development for Groundwater and Soil Remediation at the Department of Energy Headquarters Office for Environmental Management. In this position, she resolved technical issues and assessed technology readiness for challenges in groundwater and soil remediation. Currently, Dr. Wellman is manager of PNNL's EH&R sector within the Energy and Environment Directorate.
