Through geostatistical techniques of simulation conditioned by turning bands (TB), different scenarios were assessed for the analysis of environmental contamination of metals cobalt (Co), chrome (Cr), nickel (Ni), and lead (Pb) in an area of 7,291 km2, equivalent to the subregion of west from department of Antioquia. Geostatistical cartography prepared for the pessimistic case of each of the metals analyzed, report anomalous values above the standards established for the different types of rocks in the region, which would generate a moderate relative mobility for water contamination, being subjected to surface weathering processes under oxidation conditions in acidic environments. Under reducing conditions, the simulated elements would have a behavior of relative immobility and would offer environmental danger for the soils of the region. Potentially dangerous anomalous values were estimated for Co ¿ 130 mg/kg, Cr ¿ 2,507 mg/kg, Ni ¿ 138 mg/kg, and Pb 165 ¿ mg/kg.
