David Reynolds, Ph.D., PEng
Senior Principal Environmental Engineer
David Reynolds is a Senior Principal with Geosyntec Consultants based in Kingston and Guelph, Ontario is an Accredited Contaminated Sites Auditor in Western Australia, and manages the Australian operations of Geosyntec. Dave also holds Adjunct professor positions at Queen’s University and the University of Waterloo. Dave has held past positions as the leader of the Hydrogeology Research Group at the University of Western Australia and the Research Director of the Centre for Groundwater Studies in South Australia. Dave was recently a member of the NRC committee on Subsurface Characterization, Modeling, Monitoring, and Remediation of Fractured Rocks calling on his 20 plus years of practical and academic experience, ranging from fundamental bench-scale studies, to phenomena and field-scale modeling, to full-scale remediation of LNAPL and DNAPL sites. He has extensive experience in the impacts of climate change and agricultural practice on the salinity of shallow ground water resources, as well as forensic investigation of sources of salinity and other contaminants.
SESSION KEYNOTE PRESENTER - Value of Information: How Much is Enough?
Collecting Data Costs Money – Is its Value Worth its Cost?
Site characterization is a process of reducing uncertainty, with the eventual aim of developing a conceptual site model (CSM) that is appropriate for selection of an appropriate remedy likely to meet the remedial objectives of the site at the least life cycle cost. The economic cost of data collection to create a CSM is highly variable and dependent on many factors, and little in the way of formal guidance exists on the balancing of the production of data from intensive and costly site characterization activities, the associated cost of the activities, and the ultimate benefit to selecting the interim or final remedial action that achieves remedial objectives more cost effectively.
The DIVER Project (SERDP‐ER‐2313, Data Information Value to Evaluate Remediation) is developing technical guidance on remediation decision making using concepts of the value of data in both the site characterization and remediation contexts based on empirical evidence gathered by some of the most respected and successful practitioners in the field, highly detailed virtual site investigations, and application of stochastic methods to quantify the value of additional site characterization in implementing a remedy at chlorinated solvent sites. The primary research objective of the DIVER project is to develop a framework for optimization of the site characterization process, such that the total cost of investigation, the cost of achieving remedial goals, and the likelihood of failure of remedial approaches are minimized.
This presentation will provide the technical bases for the application of Value of Information (VOI) principles as applied to decision making in contaminated site investigation and remediation, and present the findings of the first stages of the DIVER project – which will underpin a key deliverable for the project, a forthcoming Practitioner’s Guide to Cost‐effective Site Investigations that should be applicable to any chlorinated solvent impacted site.
