The POLLUTEv7 program solves the one-dimensional contaminant migration equation subject to boundary conditions at the top and bottom of the soil deposit being modelled. There are three possible top boundary (i.e., the usually the point of contact between the contaminant source and the soil deposit), these are zero flux, constant concentration, and finite mass. The bottom boundary (i.e., the point of contact between the soil deposit and either a much more or much less permeable strata) may be either zero flux, constant concentration, fixed outflow, or infinite thickness.
