Mathematical model is widely used to simulate the fate and transport of contaminants in soils and groundwater. The three-dimensional multispecies transport analytical model is an essential and efficient model tool for predicting the plume behavior of decaying contaminant such as radionuclides, dissolved chlorinated solvents, nitrogen and pesticides. Most of the multispecies analytical models are derived subject to a linear equilibrium sorption process. However, the use of equilibrium sorption model has been frequently questioned as it cannot adequately account for nonequilibrium sorption process during the contaminant transport in subsurface environment. In this two-year industry-academy cooperation project, we collaborate with the Sinotech Environmental Techonology, Ltd. to develop advanced three-dimensional analytical models for rapidly predicting the plume behavior of decaying contaminants in the groundwater system subject to a nonequilibrium kinetic sorption process. In the first year, a three-dimensional analytical model for boundary sources and its corresponding computation code will be developed. In the second year, we will extend the development of the three-dimensional analytical model and its computation code to multiple internal sources. The results from this two-year project can be integrated to build an advanced three-dimensional model tools, namely, MUSTAM (Multi-Species Transport Analytical Model), for accurately predicting the plume behavior of groundwater contaminants.
