Diffusion of a pollutant into a semi-infinite soil layer can be described by the following differential equation, d²C (1) = kC dz? where D is the effective diffusion coefficient of the pollutant in the soil, and the k is the first-order decay rate of the pollutant with the soil column. If the pollutant concentration at the surface is fixed at Co, below what depth will the concentration of the pollutant be less than 10% of the surface concentration?
