The application of numerical methods to solve pollutant transport issues has become popular because of the increased importance of soil–water quality. The current study proposes a two-dimensional numerical model for the bioremediation of benzene from benzene-contaminated soil. Biopile is a technique wherein the contaminated soil is remediated through the process of biodegradation. The model used in the current study simulates benzene’s flow, transport, and biodegradation during the biopile process in saturated porous media using the Finite Difference Method. Provisions were made for the entry and exit of gases or liquids from the pile at specified positions along the bottom liner or pile centreline. The midline for the pile was employed to provide symmetry to lessen the overall complexity of the problem. The double Monod kinetic equation was used to model the bacterial growth within the biopile, whereas the fertilizer transport through soil and movement of fluids inside the soil was modelled using Advection Dispersion Equation (ADE) and Navier–Stokes’ equation. The results indicated that the amount of benzene eliminated through outflows was higher for air velocity of 5 m/s compared to air velocity of 1 m/s.
