Overview: This course provides a practical overview of the transport and fate, and natural attenuation of metals in soil and groundwater using the "Scenarios Approach". The Scenarios Approach was developed by the Savannah River National Laboratory in 2011 to provide a quick and easy framework for improving the assessment and remediation of inorganic contaminated sites. The Scenarios Approach is based on the interpretation of plume geochemistry, geochemical gradients, and specific inorganic contaminant behavior in various geochemical settings (e.g., Cr(VI) instability under low redox conditions). Understanding the various geochemical scenarios present within a plume provides an improved method for predicting metal contaminant transport and fate, and implementing effective remediation strategies.

About the Instructor: Erick McWayne has twenty-two years of professional experience in water quality management and teaching related courses. As a consultant, he managed contaminated surface water and groundwater projects for the Department of Defense and other clients. He currently provides consulting support to water quality projects and teaches courses in contaminant chemistry, transport and fate, geochemistry, hydrogeology, remediation, stormwater and surface water management, and contaminant attenuation with both the University of California Davis and the National Environmental Management Academy. Between teaching and consulting, Erick develops surface water and stormwater treatment technologies. He holds two patents on permeable reactive weir technology.
