    About the Instructor: Erick McWayne has over twenty years of experience with soil, groundwater, and geophysical investigations for the characterization of contaminant transport and fate; and teaching contaminant chemistry, transport, natural attenuation, and hydrogeology. As an environmental consultant, Mr. McWayne served as a project manager for remedial investigations and feasibility studies at numerous Department of Defense and other contaminated sites. He currently manages NEMA and teaches transport and fate, environmental chemistry, and hydrogeology around the country.
