POLLUTANT DYNAMICS AND REMEDIATION OF CONTAMINATED SITES

Course objectives

The course contributes to the achievement of the training objectives referred to in the Manifesto of Studies of the master’s degree in applied Geology. In particular, the course aims to provide students with the basic knowledge related to the phenomena of contamination of soils and groundwater in order to: a) Understand the mechanisms that govern the dispersion of contaminants in soil and groundwater based on the knowledge of the characteristics of the contaminants and of the environmental matrices of interest; b) Select the intervention strategies for the recovery and redevelopment of contaminated sites; c) Evaluate the adequacy of the potentially applicable solutions in the frame of the national regulatory framework Students who have passed the examination will have known and understood (descriptor 1: acquired knowledge): • Fundamentals on the transport phenomena of contaminants in soils and groundwater with particular reference to the chemical and physical characteristics of the contaminants and environmental matrices of interest • Main technologies for the characterization of contaminated sites • Fundamentals and main types of technologies applicable in the remediation of contaminated sites • Technical / administrative procedures in the management of a contaminated site in the national regulatory context Students have passed the examination will be able to (descriptor 2 - acquired skills) • Set up a characterization plan for a potentially contaminated site • Identify the most appropriate strategy in the reclamation / securing of a contaminated site • Set up experimental activities preliminary to the selection of the best strategy / technology for the reclamation of a polluted site During the lectures, in addition to the acquisition of the aforementioned skills , the reference to real cases of contamination, with direct interaction with the students and stimulation to provide possible solutions to the problems presented, will increase critical and judgmental skills (descriptor 3) and the ability to communicate what has been learned (descriptor 4)

1.Transport and fate of pollutants in soils and subsoils (2.5 CFU) 1.1 Definition and Description of the various sources of pollution of soil and groundwater, with particular reference to the environmental impact of industrial activities. 1.2 Classification of pollutants on the basis of the chemical / physical properties and characteristics that determine their fate in soils and subsoils. 1.3 non-aqueous phase liquid (NAPL) and their dispersion in the environment. Sampling methodologies in the saturated and unsaturated zones. 1.4 Mechanisms of interaction between contaminants and soils / subsoils (adsorption, volatilization and biodegradation). 1.5 Principles of mathematical modeling of flow in saturated zone and unsaturated zone. 1.6 Examples of wide-spread computer codes for the simulation of reactive transport of contaminants in the saturated zone. 2. Regulatory Framework (0.5 CFU) 2.1 The laws for the protection of soil. 2.2 Laws concerning the quality of water. 2.3 Outline of EuropeanCommunity legislation. 3. Technologies for the remediation of contaminated soils and groundwater (2.5 CFU) 3.1 Safety measures for soil and ground water. active and passive containement systems (hydraulic and waterproof barriers diaphragms). 3.2 Classification of remediation (in-situ, on / off site, chemical, physical and biological). 3.3 Review of established technologies for the remediation of contaminated soils and groundwater. 3.4 Criteria for selection of the most appropriate interventions (cost / benefit analysis). 3.5 Advanced technologies for the remediation in-situ: Permeable Reactive Barriers, advanced systems of Pump & Treat, in-situ bioremediation, monitored natural attenuation and accelerated natural attenuation. 4. Numerical Exercises (3 CFU) 4.1 Study and use of software for georeferenced representation of contamination data. 4.2 Study and use of software for the expedited assessment of transport and degradation of contaminants. 4.3 Study and use of software for site-specific Risk Analysis at contaminated sites.
Prerequisites
- Basic knowledge of mathematics necessary for the understanding of the transport and dispersion of contaminants (study of continuous functions, total and partial derivatives, differential equations to partial derivatives (outline)) - basic knowledge of general chemistry and organic chemistry
Books
educational material provided by the teacher Digital material on the Eiduco platform
Teaching mode
The course is mainly carried out in traditional ways through lectures. In order to train the students in the management of the process of remediation of a polluted site, from the evaluation of the characterization data, the definition of the conceptual site model, application of the risk analysis procedure, until the choice of the intervention strategy, tutorials with dedicated software and case study discussion will be performed. The course will also be carried out with the use of the Eiduco digital platform which will allow the student to interact both during the lesson and subsequently with the teacher and elaborate the didactic material presented
Exam mode
The final examination will be carried out through an oral interview with the candidate aimed at ascertaining the acquired knowledge, as defined in the training objectives. In particular, the interview will serve to verify, on the one hand, the acquisition of scientific knowledge introduced in the course and, on the other, the ability of the student to address the technical / procedural path of managing a contaminated site and propose appropriate remediation solutions. This second part will take place by submitting a contamination scenario to the candidate and verifying with him the progressive capacity to define the modalities of intervention. For the exam, the candidate will prepare a brief PowerPoint presentation (or similar), choosing to delve deeper into one of the topics covered in class, present a case study, or propose a topic not discussed in the lectures but related to the themes of the course.
