Learning outcomes
KNOWLEDGE AND UNDERSTANDING:
The course aims to provide the students with theoretical and technical skills on the geotechnical aspects of design and construction of landfills and of remediation of polluted sites. After the course, the students know the Italian rules concerning waste landfills and remediation of polluted sites and they are able to: plan investigations on a polluted site, perform the site-specific risk analysis, select the most appropriate remediation technology and design it as far as the geotechnical aspects in concerned, design and control the bottom and cover system of waste landfills.
CAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
To make the students able to apply the acquired knowledge, they are guided in performing the risk analysis and in selecting the remediation technology for a contaminated site, to be presented as technical note at the exam. They have also to answer some questions as final examination. The course aims at providing the student with the ability of: 1) selecting the most appropriate investigation techniques; 2) recognizing the most appropriate approach to analyse and deal with the issues; 3) proposing and developing a design solution.
TRANSVERSAL SKILLS:
Cooperative learning and study groups for some subjects are encouraged. Technical visits and on-site team practice are organized at specialised laboratories and, when available, at contaminated sites or waste landfills. All these activities improve cooperation and communication skills, autonomous assessment and learning ability of the students.

Program
Pollutant migration through soils. Interaction phenomena soil-water-pollutants. Migration mechanisms: testing and modelling. Chemical compatibility. Analysis of the italian laws and regulations for waste disposal by landfills and polluted soils. Geotechnical design and construction of waste landfills: bottom and sidewall liners, cover system. Compacted clay liners, geosinthetic clay liners, geomembranes, geotextiles and related hydraulic and mechanical characteristics. Mechanical behaviour of wastes. Chemical and geotechnical characterisation of polluted sites. Risk assessment and analysis. Remedial strategy. Remediation technologies. Confinement of polluted sites by cut-off walls: technologies and design. Plastic cement-bentonite cutoffs: performance, mix-design, construction and controls. Cutoffs by jet-grouting and by different types of deep soil mixing. Technologies for remediation of polluted soils and groundwater: stabilisation/solidification, on site and off- site physical treatments, termal remediations. Permeable reactive barriers.

Development of the examination
LEARNING EVALUATION METHODS
Risk analisys (technical report) to be delivered at the exam + written test with a question on theory and an exercise.

LEARNING EVALUATION CRITERIA
Written test: to evaluate students' ability in applying theory and their knowlegde of parameters' unit and magnitude. Oral exam: to evaluate students' theoretical knowledge.

LEARNING MEASUREMENT CRITERIA
The technical report, the theoretical question and the exercise are 10/30 each.

FINAL MARK ALLOCATION CRITERIA
Arithmetic mean of the technical report, theoretical question and exercise. Full marks are assigned if the student shows a study in depth and a proper technical language.
