Abstract : This study assessed the extent of downslope movement of heavy metals from Agodi Gate automobile station in Ibadan using Geographic Information System (GIS). Well water (groundwater) samples were collected and analyzed to assess concentrations of lead (Pb), Nickel (Ni) and Chromium (Cr) using Atomic Adsorption Spectrophotometer. GIS was used to map and measure the lateral dispersal extents of those heavy metals from sources. Pb, Ni and Cr concentrations in soil samples decrease down the slope from 485-2mg/kg, 33-10mg/kg and 18-0.0mg/kg with dispersal extents of 269.09m, 321.66m and 240m, respectively. The heavy metals concentrations in the water samples however decrease down the slope from 0.25-0.00mg/l, 0.18-0.00mg/l and 0.00-0.00mg/l with Pb and Ni contamination extents of 61.78m and 131.66m, respectively. The order of heavy metals contamination degree is Pb>Ni>Cr while the order of heavy metals contamination extent is Ni>Pb>Cr.
