This work presents geostatistical algorithms for the spatial prediction of concentration of metal (Pb) using software “Multigeo”: ordinary kriging and ordinary cokriging. The techniques are illustrated using concentrations of some metals measured at 200 points of Leman Lake and concentration of metal Pb measured at 175 points of Leman Lake. Cross-validation is used to compare the prediction performances of ordinary kriging and ordinary cokriging with the various numbers of secondary variables (from cokriging with the only secondary variable to cokriging with the eight secondary variables).
