The course provides the basic knowledge in the field of environmental engineering. In particular, the perspective student will acquire the necessary understanding of pollution phenomena and their interaction among the different environmental matrixes (i.e.: air, soil and water). A specific attention is given to water depuration processes and their related plants’ components. A third section of the course is focused on the environmental law and regulations with respect to the Environmental Impact Assessment and the technical requirements related to environmental monitoring. Finally, different seminars will enable the student to develop a deeper understanding on existing and perspective challenges for environmental engineering having a high societal impact.
In order to follow the course, the following teachings and their relative proficiencies are required:
Pollution and environmental impact: definition and origins. Pollution phenomena and their interaction with the different environmental sectors (i.e.: water, air, soil). Pollution sources. Pollutants classification. Basic principles for the pollution phenomena assessment: definitions and measure of concentrations; chemical and physical equilibria; reaction kinetics; mass balances. General principles of pollution prevention and control. The ecosystem as environmental resource. The environmental impact, its meaningfulness and incidence. Disturbance threshold (temporary - durable impacts). The environmental re-equilibrium (the concept of resilience). The right to use of resources (sic utere tuo ut alienum non laedas). The legislative decree 152/2006. The sustainable development principle. The corrective decree (D.L. 128/2010). The environmental action and its related activities. The principles of environmental action protection and their execution. The execution of prevention principle: procedures. The execution of precaution principle: procedures. Monitoring activities as instrument of environmental control, protection and safeguard.

The final exam will be oral. It is structured through a preliminary discussion about the exercitations/tests/reports individually developed by each student either during or at the end of the course. In particular, the theoretical and calculus approaches, developed during the course syllabus, will be deepened.
The student must demonstrate a full proficiency about the course subjects, with a special focus on their underlying logic and methodology. Moreover, each student should demonstrate his level of understanding on the formal, logical, theoretical, as well as practical implication of the syllabus contents and the relative taught procedures.
