About the Instructor: Erick McWayne has twenty years experience with surface water, soil, groundwater, and geophysical investigations for the characterization of contaminant transport and fate; and teaching contaminant chemistry, transport, natural attenuation, hydrogeology, and stormwater chemistry. 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 workshops on transport and fate, environmental chemistry, hydrogeology, and stormwater around the country.
