Contaminant plume spreading and oxygen-limited biodegradation of such plumes were analyzed. Relations among the plume`s spreading coefficient (macrodispersivity), its mixing coefficient, and the statistics of self-similar log-conductivity were investigated. The finite size of the contaminant plume was taken into account. Spectral analysis and numerical modeling were used to solve the stochastic differential equations governing the transport of soluble plumes in self-similar heterogeneous formations for saturated and unsaturated cases. In the numerical simulations, Monod kinetics were used to simulate the contaminants` degradation in the presence of oxygen. The numerical modeling effort uses the finite difference method for flow simulation combined with the random walk approach for transport. Results of this investigation will be of interest to groundwater hydrologists and environmental engineers working on the fate of contaminant plumes in heterogeneous subsurface.
