There is no enough information about metal transport parameters in residual soil. These soils are generally structured and still there is no answer to what happens with the contaminant transport parameters when an acid solution with metal percolates this material with different structure. The objective of this study was to determine the contaminant transport parameters for Cd, Ni, Cu and Zn metals in an acid multispecies solution to a residual soil from south Brazil with an undisturbed and remolded structure. Column tests were carried out to determine the k<sub>d</sub>, R<sub>d</sub>, D<sub>h</sub> transport parameters. It was possible conclude that the magnitude of the k<sub>d</sub>, R<sub>d</sub> and D<sub>h</sub> parameter did not vary significantly with the soil structure.
