Abstract : The purpose of this project was to implement the Bioplume II flow and transport code to simulate the results of the MADE-2 experiment and evaluate the appropriateness and applicability of the Bioplume II code at similar sites. The MADE-2 experiment was a controlled field experiment involving the injection of several aromatic hydrocarbons and a nonreactive tracer into an uncontaminated aquifer (Stauffer et al., 1994). Bioplume II is a numerical computer model that simulates groundwater flow, as well as fate and transport of contaminants in groundwater. Of particular interest in this study is the ability of Bioplume II to simulate the fate and transport of organic contaminant's under the influence of biologic and abiotic degradation. This objective has evolved from observations at many sites that indicate natural attenuation plays a significant role in the fate and transport of organic compounds (Stauffer et al., 1994, Wiedemeier et a!., 1995). Natural attenuation is the term describing the in situ reduction in contaminant concentration and mass by biologic and/or abiotic mechanisms which may result in delayed plume migration or, in some cases, may result in plume stabilization or reduction of plume size. size.
