Personal Bio

Dr. Andy Stoddard is based near Leesburg, Virginia where he has been employed since 2002 as a Principal Environmental Engineer with Dynamic Solutions, LLC. Prior to his employment with Dynamic Solutions, he worked in Northern Virginia for Tetra Tech, Inc. and Science Applications International Corporation. After completing his master’s degree in 1970, he worked for the U.S. Environmental Protection Agency in Chicago where he developed one of the first water quality models to be used to evaluate the effectiveness of technology-based effluent controls mandated by the Clean Water Act (CWA).

He is a nationally recognized expert for watershed, hydrodynamic, nutrients, eutrophication, oxygen depletion, and aquatic ecosystem models of rivers, lakes/reservoirs, estuaries, and coastal waters. He has expertise with EPA-supported public domain models including QUAL2K, BASINS/HSPF, WASP7, and EFDC and he has used these models for a range of CWA-related assessments including watershed-based policy evaluations, compliance with water quality targets, and Total Maximum Daily Load (TMDL) studies.

His contributions to the field include national and international conference presentations, service as a peer reviewer for journals, publication of peer-reviewed journal articles, and book chapters. His contributions to peer-reviewed book chapters include: "Oceanic Processes in Marine Pollution, Volume 5:  Urban wastes in coastal marine environments" [New York Bight] (1988); "Coastal and Estuarine studies, Novel Phytoplankton Blooms: Causes and Impacts of Recurrent Brown tides and other Unusual Blooms" [Peconic Estuary] (1989) and "The Hudson River Estuary" (2006). Dr. Stoddard is the principal co-author of a peer-reviewed book documenting successes of the Clean Water Act "Municipal Wastewater Treatment: Evaluating Improvements in National Water Quality"; the book was published in 2002 by John Wiley & Sons, Inc. The CWA book earned recognition from EPA's Office of Water as being “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.”

He began teaching in the graduate program of Johns Hopkins University, Whiting School of Engineering in 2003 as a co-instructor for Modeling Contaminant Migration through Multi-Media Systems. In 2007, he began teaching Environmental Monitoring and Sampling and in 2015 began co-teaching the monitoring course.  Both courses have been offered online since 2014-2015.
