000063473 520__ $$aA one-dimensional (1-D) multi-component model accounting    for hydrological transport inorganic equilibrium  chemistry   and microbial activity during kinetically  controlled biodegradation in groundwater of compounds such  as  benzene, toluene, ethylbenzene and xylenes (BTEX) is   presented. The problem is solved numerically using an   operator-splitting  method to couple advective–dispersive   transport of organic and inorganic solutes with a   geochemical equilibrium  package PHREEQC and a   biodegradation module. The transport  equations for   inorganic solutes are solved for total  aqueous component   concentrations. Changes in such  concentrations due to   precipitation/dissolution of minerals  and chemical   speciation are accounted for within PHREEQC.  For chemical   elements occurring in multiple valence states,  separate   components are defined and transported. The   biodegradation  module simulates the sequential or  parallel  activity of  multiple bacterial groups attached  to soils and  their  biochemical effects. The model has  been evaluated by   comparison with an existing model  simulation of a 1-D   inorganic redox problem. An  application of the model is   shown for a synthetic case  where BTEX compounds are   degraded by sequential reduction  of aqueous electron   acceptors.
