On Monday and Tuesday evenings, optional computer modelling workshops will be held to demonstrate the application of environmental decision support software, and groundwater and risk assessment modelling tools. Participants in these workshops will become familiar with Environmental Data Management for site characterization and cleanups at storage tank sites and contaminated sites (EarthSoft, Inc., Massachusetts), and the input parameters required to build and calibrate groundwater flow models (Waterloo Hydrolgeologic, Waterloo, Canada)

.
Participants will be introduced to various graphical tools for evaluating well capture zones, determining preferred flow and contaminant migration pathways, and optimizing groundwater remediation systems. The workshops will use examples from existing sites in Canada and the U.S. to evaluate risk assessment, natural attenuation, endpoint analysis, three-dimensional groundwater flow, preferred migration and exposure pathways, and the effectiveness of groundwater treatment systems. The workshops will be conducted by experts from the United States and Canada.
