The presence of a residual concentration, which was higher than the reference value, was found to be the limiting factor for the practical use of landfarming. In the research on the decrease of the residual concentration, bio-availability was found tobe crucial. The velocity of the release of non-bio-available pollutants could not be increased. This leads to a two-step approach in which the bio-available fraction can be removed in a short intensive period (intensive landfarming), followed by a longerextensive period (extensive landfarming) for the non-bio-available fraction in which the contaminant has time to desorb.
