STOCHASTIC ANALYSIS OF OXYGEN-LIMITED BIODEGRADATION IN HETEROGENEOUS AQUIFERS WITH TRANSIENT MICROBIAL DYNAMICS

Development of nonlinear partial differential equations for describing the transport and transformation of a contaminant and dissolved oxygen in the presence of transient microbial growth dynamics. Biodegradation expression is a function of the mean and perturbation concentrations using a spectral approach. Analysis of aquifer heterogeneitis and their influence on coefficients of decay and microbial death. Field scale gouverning transport equations for oxygen. Limited biodegradation of the contaminant in presence of transiant microbial dynamics are presented. Discussion with graphical presentation of benzene biodegradation and comparison with another work.
