UNIT V CONTAMINATED SITE REMEDIATION 10 Contaminaed sites - Fate and behaviour of toxics and persistent substances in the environment – Engineering Issues in Site Remediation - Site Characterization - Framework for risk assessment at landfill sites - Remediation Principles: Source Control and Management of Migration Covers, Cut-off Walls, Solidification / Stabilization - Pump-and-Treat Systems - Solvent Vapor Extraction, Air Sparging, Soil Flushing – Bioremediation - Natural Attenuation - Remedy Selection and Risk Assessment – Geotechnical Aspects of In Situ Remediation Technology - Specific case studies in contaminated site remediation – Rehabilitation of Open dumps- Landfill Mining TOTAL: 45 PERIODS
OUTCOMES: On Completion of the Course, the Candidate should:
- Have an overview of the Indian and international landfill regulations and guidelines for the design, construction, operation and management of landfills
- understand the design and construction of landfills, processes in landfills, methods for management and treatment of landfill gas and leachate
- have an in-depth understanding of the key pollutants in leachate and gas, their potential environmental impacts and the engineering design and performance of control systems used to manage and treat pollutant and waste emissions from sites.
- Be able to apply a risk based assessment of contaminated sites and implement site remediation technologies
