Abstract
The U.S. Environmental Protection Agency's program, MULTIMED, was evaluated using a parametric analysis and result comparisons the with programs MODFLOW and MT3D. The validity and accuracy of the MULTIMED model results were determined and independent parameter sensitivities identified. The dilution calculations in the model are sensitive to several parameters. A parameter determined critical is the seepage velocity which is used in the transport calculations of the model, as well as a "Near Mixing Factor". Under Florida's aquifer conditions, the Near Mixing Factor as calculated in the model is susceptible to overestimating the dilution of the initial concentration due to relatively high recharge rates and low hydraulic conductivities. Florida's aquifer conditions also typically result in Near Mixing Factor values greater than one, for which the model's analytical solutions are not valid.
