Andrew Stoddard, Ph.D. - Principal Environmental Engineer
Dr. Stoddard is a nationally recognized water quality modeling expert with 33 years of professional experience in academic research and environmental consulting. He specializes in the application of hydrodynamic, hydraulic and surface water quality models for assessments of the ecological effectiveness and environmental benefits of water pollution control policies and regulations as mandated by the Clean Water Act. He has extensive experience in conceptualizing, planning and executing innovative “data mining” activities of large databases for (a) data assimilation in environmental models and (b) statistical analyses of national, regional, and local-scale water quality status and trends. Using rigorous "data mining" techniques, Dr. Stoddard was able to detect, for the first time, statistically significant national, regional and local-scale “signals" of water quality improvements that have resulted, in part, from the technology-based regulatory policies of the Clean Water Act. The results of this important study were published in 2002 by John Wiley & Sons, Inc. as Municipal Wastewater Treatment: Evaluating Improvements in National Water Quality. He has also authored a number of technical publications including peer reviewed book chapters published in Oceanic Processes in Marine Pollution, Vol. 5: Urban wastes in coastal marine environments (1988); Coastal and estuarine studies, Novel phytoplankton blooms: Causes and impacts of recurrent brown tides and other unusual blooms (1989) and The Hudson River Ecosystem (in press,2004). Dr. Stoddard developed comprehensive pre-processing software to incorporate EPA’s WASP5 eutrophication and toxics water quality models as the surface water quality model in EPA’s Office of Water National Water Pollution Control Assessment Model (NWPCAM). The NWPCAM framework, applied on a national-scale using EPA’s River Reach File-based hydrologic network of inland rivers, lakes and tidal waters, is used for assessments of policy-related water quality and economic benefits. Dr. Stoddard is a part-time instructor for a graduate level multi-media environmental modeling course. Dr. Stoddard has specific expertise in the following capabilities: Hydrodynamic Modeling | Sediment Transport Modeling | Chemical Fate Modeling | Water Quality and Eutrophication Modeling | TMDLs and Waste Load Allocations | Regulatory Policy Evaluations | Industrial Discharge Analysis Modeling.
