Sampling for the evaluation of soil pollution levels is extremely difficult. Soil is highly anisotropic, and consequently, assessing its physicochemical characteristics is hard, and the probability of occurrence of errors in the evaluation of site pollution levels is high. Many studies have observed that, in procedures for measuring pollution levels, the uncertainty resulting from sampling is higher than that from errors or uncertainty made in analysis. In addition, procedures for pollution level evaluation are not clear, allowing many errors of overestimating or underestimating site pollution levels to occur. In the evaluation of site pollution levels, the selection of sampling points and the determination of sampling depths are extremely important. In states where polluted locations are not clearly identified, the form and concentration of pollution can be evaluated differently depending on the sampling plans.
