Environmental Engineering

Legislation. The legislation for the remediation of contaminated sites. Technical and legislative activities for remediation of contaminated sites. Evolution in time of legislation. Conceptual model of the site. Risk analysis. 1 CFU equal to 25 hours of student commitment of which: • 10 hours between lectures, exercises and seminars; • 15 hours of individual study. Characterization of a contaminated site. Identification of the sources of contamination. Methods and sampling of soil, subsoil and groundwater. Extraction and identification of pollutants from soils. Checking of the contamination level. Analytical techniques. Characterization planning of site. Conceptual site model. Remediation technologies of soils and groundwater: Main in situ and ex situ remediation technologies. Criteria for selecting technologies. 2 CFU equal to 50 hours of student commitment of which: • 20 hours between lectures, exercises and seminars; • 30 hours of individual study. Monitoring of the remediation processes. Biological treatment processes: application of biological processes. Natural attenuation. Bio-barrier. Solid phase treatment through composting/humification. Bioremediation of MTBE contaminated groundwater. Remediation through co-metabolic processes. Phytoremediation treatments. Bioventing and air sparging treatments. Biofiltration for the treatment of gaseous emissions of VOCs. Engineering and management aspects. Physical-chemical technologies: in situ chemical oxidation, permeable reactive barriers, soil washing/flushing, thermal desorption. Stabilization-solidification. Remediation of uncontrolled/old landfills. Landfill mining. Operation for landfill safety: methodological issues, design solutions and applications. Sediment. Characterization of a sediment. Dredging: the environmental dredging, mechanical dredging, hydraulic dredging, types of dredgers, dredging efficiency, water treatment is. Sediments Treatments. purposes of processing. Pretreatment: separation, dehydration. Physical / chemical treatment and biological treatment. The restoration of a polluted site. Sustainability in remediation projects ("sustainable remediation") 6 CFU equal to 150 hours of student commitment of which: • 60 hours between lectures, exercises and seminars; • 90 hours of individual study.

For a good learning of the subject, elementary knowledge of the disciplines of geology, geotechnics, sanitary and environmental engineering are useful.

Lesson plans and handouts

The lessons will take place in the classroom and the student is invited to follow the lessons in order to simplify the study of the matter

The learning objectives achieved by the students will be analyzed organically within the profit exam at the end of the course. The exam will consist of the discussion of a technical report and an oral test. The discussion of the technical report is an essential condition to be admitted to the oral test. The oral exam includes questions from the program and discussions related to the exercises conducted during the course. The exam will consist of oral questions extracted from the program and discussions on practical exercises carried out during the course. During the oral examination, the student must be able to orient himself from a scientific, regulatory and ethical point of view, effectively justifying the design choices to be taken for the success of the remediation and requalify of the contaminated site.

The course will be divided into lectures, during which the fundamental knowledge relating to the activities necessary to proceed with the remediation of a contaminated site will be imparted, distinguishing between in situ, on site and ex situ technologies and analyzing the processes chemical, physical and biological which are the basis of the different technologies. Particular attention will be paid to innovative and sustainable technologies. Working groups will be organized for the study and evaluation of remediation projects. During the course, numerical exercises and in-depth studies will be carried out, on the design aspects of some of the remediation technologies, and educational visits will be organized to allow students to observe ongoing remediation and meet the operators who carry out the remediation of a contaminated site in the field. Specific seminars will also be organized to present particular aspects of the course (legislation, innovative technologies and/or methodologies) and real cases of remediation.
