As part of the 9th International Conference on Remediation of Chlorinated and Recalcitrant Compounds (Monterey, California; May 19-22, 2014), we will be co-teaching the following short course on Wednesday, 21 May 2014 from 1:00–5:00 p.m.
~~~~~~~~~~~~~~~~~
Groundwater Geochemistry and Practical Assessment of Redox-Based Remediation
Instructors: Paul Tratnyek, Ph.D. (Oregon Health & Science University), Richard L. Johnson, Ph.D. (Oregon Health & Science University), and Bill Deutsch (Geochemistry Services LLC)
Objective: Advance the state-of-the-practice of all redox-related remediation technologies by providing a more comprehensive, inclusive and synergistic understanding. Remediation project managers, design engineers, site characterization planners, responsible parties and regulators will benefit from this course.
Overview: In situ remediation of contaminated groundwater involves not only contaminant concentration reduction but also geochemical interactions with the aquifer solid phase. This class will provide an introduction to groundwater geochemistry with a focus on redox reactions because the evaluation of remediation performance often necessitates accurate assessment of in situ redox conditions. However, the existing redox- based assessment tools (e.g., oxidation-reduction potential [ORP] and natural oxidant demand [NOD]) are not adequate for selecting among alternative technologies. Redox-based methods for optimization of particular technology deployments are not sufficiently well developed to be used quantitatively. This short course will review the state of current/best practice, summarize important recent developments and preview some current research that will improve site assessment and remediation performance. The approach will emphasize core concepts that apply across the whole range of redox-based remediation strategies, ranging from natural attenuation to chemical oxidation and reduction.
