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.
