Exposure Assessment Models


The Multimedia Exposure Assessment Model (MULTIMED) for exposure assessment simulates the movement of contaminants leaching from a waste disposal facility. The model consists of a number of modules which predict concentrations at a receptor due to transport in the subsurface, surface air, or air. To enhance the user-friendly nature of the model, separate interactive pre- (PREMED) and post-processing (POSTMED) programs allow the user to create and edit input and plot model output.
