Keywords: soil, soil pollution, soil remediation, soil, chemical reactions, water flow, solute transport  

Soils, the upper meters of the earth's crust, forming the interface between the various components of the ecosystem earth: geosphere, biosphere, hydrosphere and atmosphere. A good understanding of the soil system is necessary for assessing both environmental (risks) and the possibilities of restoring soil (soil remediation). This course examines the technological aspects of soil science. It will include the interaction between biological, physical and chemical soil processes that determine the behavior of (polluting) substances in the soil . In Part 1 of the course short attention is given to soil formation and soil classification because of their interest in cartographic applications, and their application in regional and European soil policy. Most attention in Part 1 is to describe and understand chemical reactions that substances undergo in soil: sorption / desorption, precipitation / solution reactions, complex formation, speciation in soil solution. The content is taught on the basis of practical exercises supported by a computer code for geochemical speciation. Volume 2 goes deeper into the physical aspects of soil science: water flow and transport of solutes. The knowledge gained is ultimately brought together in a practical computer exercise involving the spread of a contaminant in the soil.
