We introduce an example of a detailed study of soil texture and geochemistry with the aim of designing appropriate soil washing systems. Concretely, we have studied soils affected by the mining works of “Los Rueldos” (Asturias, Spain). After an initial characterization, composite, representative samples were taken and ICP-MS analysis was carried out. Results showed very high concentrations of As, and significant presence of heavy metals such Hg, Pb and Zn specially in silt-clay fractions obtained after wet sie...
