A rather simple, yet complete, mathematical model for the pulsed dispersion of trace chemical concentrations in a water‐saturated sorbing porous medium is stated, and the resulting integrodifferential equation of transport is solved via Laplace transform methods. A typical example of a soil water dispersion system is discussed with the aid of free and sorbed phase concentration distribution curves.
