Learning outcomes
Students will acquire technical and legal tools to undertake the remediation of polluted sites. In particular they will acquire the capacity to select the remedial technologies, to evaluate their efficacy and to design them (as regards vadose soil and aquifers) in relation to the risk based remedial goals and in pursuance of European and Italian law.
Course contents
Introduction to the pollution of sites (typology of polluted sites, mechanisms of pollutants propagation in the environment), current regulations.
Components of soil. Origin and properties of the main pollutants (hydrocarbons, metals, CAH, PAH, BTEX, PCB, Dioxins, Pesticides, ...). Interaction of soil-pollutants and distribution of contaminants in solid, liquid, gaseous and non aqueous liquid phase; determination of the presence of NAPL and composition at the equilibrium (for one and more components). Mass transfer phenomena in soil, experimental determination of mass transfer coefficients.
Basic principle of hydrogeology (in one, two and three phase systems), contaminants transport in saturated and vadose soil, simplified analytical solutions.
Methods of site assessment and interpretation of results, extension of the polluted areas (sources of contamination).
Description of the basic principles, applicability, limitations, design methods and costs of the main in situ and on-site remedial technologies for soils and groundwater (Pump&Treat, Air Sparging, Biosparging e Cometabolic Air Sparging, Permeable Reactive Barriers, In situ Chemical Oxidation, Natural Attenuation, Venting e Bioventing, Bioslurping, Excavation, Soil Washing, Biopile, Landfarming, Fitoremediation, Stabilization, Inertization, Thermal Desorption, Physical Barriers).
Risk Assessment of polluted sites (identification of the source of the contamination, evaluation of representative concentrations, identification of exposure pathway, critical review of the transport models, identification of the receptors, assessment of exposure parameters, calculation of the risk and the cleanup targets with the deterministic method and the Monte Carlo analysis).
