| Abstract: | Grade estimates are often of weak precision in the case of heterogeneous media, due to their high variability, even at small scale. Qualitative information is then useful to improve the quality of the estimates, without prohibitive additional costs. How can we sample such variables, and detect the ones that are of interest for the estimation of grades? The general methodology is presented and then illustrated for the estimation of the benzo(a)pyren (a polycyclic aromatic hydrocarbon, PAH) concentration in soils, sampled on a former coking plant.
