changes continuously and the amount of contaminant adsorbed on the soil surface
is adjusted accordingly. If the supply of volatile liquid is large compared to the
total adsorption capacity of the soil, this adjustment is slow and evaporation
approaches an apparent steady state. In the depletion stage, the soil already enri-
ched in less volatile components loses the volatile components slowly. The soil
still contains a small proportion of the more volatile components and does not lose
them completely until all components have disappeared.
