Aims :

To describe the underlying principles for design and construction of waste facilities and remediation of polluted site and to summarize the current state of practice in the field of environmental geotechnics.

Topics :

Part 1. Pollutant migration through soils. Interaction phenomena soil-water-pollutants. Migration mechanisms: testing and modelling. Chemical compatibility.
Part 2. Waste disposal by landfills. Siting. Natural, artificial and composite barrier. Design of compacted clay liners. Construction procedures. Test-pad. Controls during and after construction. In situ permeability tests. Leachate drainage and removal system. Cover system. Geosynthetic clay liners. Waste landfill stability. Mechanical behaviour of waste, shear strength parameters of each landfill element and interface. Rehabilitation of old landfills.
Part 3. Remediation of polluted lands. Geotechnical and chemical characterization. Legal aspects (D.M. 471/99). Remediation technologies: vitrification, degradation, inertization, soil washing, soil venting, air sparging. Encapsulation: cover systems, perimetral cut-off walls. Design of impervious diaphragms. Soil-bentonite, self-hardening and jet-grouting cut-off walls. Permeable reactive barriers.
