David Reynolds, Ph.D., P.Eng. (Ontario) has been invited by the National Academy of Sciences to present a talk as part of a four-part series on Environmental Dynamics and Exposure Pathways of Subsurface Contaminants to the Board on Earth Sciences and Resources in Washington, D.C. on April 26, 2018.
His presentation, entitled "Understanding Fluid Flow and Contaminant Transport in Rock: The First Step on a Long Road," will focus on the interaction between fluids and heterogeneous rocks in the subsurface. Identification, characterization, visualization, and monitoring of potential fluid pathways (e.g., faults, fractures, contacts between rock units) and fluid behavior will be discussed. The importance of modeling across scales for providing links back to issues raised in the Board on Chemical Sciences and Technology (BCST) and Board on Environmental Studies and Toxicology (BEST) sessions also will be considered. Other areas to be explored are analytic approaches (e.g., isotopic analysis) for characterizing the origins of potentially harmful substances in subsurface locations.
David Reynolds is a Senior Principal Environmental Engineer based in Ontario focused on the development and implementation of groundwater remediation technologies and management strategies for complex sites with challenging hydrogeological conditions. Dave has served as project manager, director, or technical specialist on multiple site investigations, litigation support cases, remediation feasibility studies, pilot and full-scale remediation projects, and innovative technology developments and transfers.
During the four-part series on Environmental Dynamics and Exposure Pathways of Subsurface Contaminants, attendees will explore scientific issues concerning transport, transformation, and exposure pathways of subsurface contaminants, such as metals, organics, and radionuclides. Examples from a wide range of potential applications will include waste site management decision-making, characterizing the spread of contaminants from abandoned mines, and pollution prevention planning for energy development.
The Board on Earth Sciences and Resources was established in 1988 to provide a focal point for activities related to Earth science policy. Through its committees, panels, and working groups, it oversees a wide range of Earth science issues, including research, the environment, natural hazards, resources, geographic science and geosptial information, and data and education. It also provides guidance on U.S. participation in international Earth science programs.
The National Academies of Sciences, Engineering, and Medicine are the United States' pre-eminent source of high-quality, objective advice on science, engineering, and health matters.
