Andy Stoddard is a senior environmental engineer with Dynamic Solutions, LLC in Knoxville, Tennessee. He has over four decades’ experience performing federal, academic, and consulting projects related to watershed hydrology, nutrient biogeochemistry, toxic chemicals, oxygen depletion, eutrophication, sediment diagenesis and aquatic ecology. He is nationally recognized as an expert for his applications of EPA-supported public domain models (EFDC, WASP, and QUAL2K) for Clean Water Act (CWA)-related studies. He was principal co-author of a book that explored the cause-effect relationship of CWA effluent regulations on long-term trend improvements in national-scale water quality conditions. This study earned recognition from EPA’s Office of Water as “the first national-scale study to provide a rigorous evaluation of the effectiveness of the effluent regulation policies in achieving the ‘fishable and swimmable’ goals of the CWA.”

Stoddard is a co-instructor for the courses, Modeling Contaminant Migration through Multimedia Systems and Environmental Monitoring and Sampling in Johns Hopkins University’s Engineering for Professionals programs.
