Abstract : Abstract In recent years, many hydrgeochemical models have appeared for simulating subsurface solute transport in homogeneous and heterogeneous porous media. Most of these models are deal with the porous media are chemically homogeneous. The hydrological transport of solute can be described by a set of linear partial differential equations, and the chemical equilibrium reactions are described by a set of nonlinear algebraic equations. In this paper a reacting nonlinear adsorbing solute transport in chemically heterogeneous soils is studied. The adsorption is assumed to be adequately described with the Freundlish equation. Random variation of the adsorption coefficient is assumed to describe the chemical heterogeneous of the porous media. The mass action, transport, and site constraint equations are expressed in a differential/algebraic form and solved simultaneously. In the mass action equations describing complexation and sorption process, the activities of the species in the aqueous phase are approximated using the Davies equation. The efficiency of several algorithms for solving the problem of solute transport in chemically heterogeneous porous medium has been studied. In particular, the relative efficiency of competing algorithms is evaluated as a function of the nature of the chemistry.
