GEO-ENVIRONMENTAL ENGINEERING

 LPTC

3003

OBJECTIVE:
• The student acquires the knowledge on the Geotechnical engineering problems associated with soil contamination, safe disposal of waste and remediate the contaminated soils by different techniques thereby protecting environment.

UNIT I

GENERATION OF WASTES AND CONSQUENCES OF SOIL POLLUTION

8

Introduction to Geo environmental engineering – Environmental cycle – Sources, production and classification of waste – Causes of soil pollution – Factors governing soil pollution interaction clay minerals - Failures of foundation due to waste movement.

UNIT II

SITE SELECTION AND SAFE DISPOSAL OF WASTE

10

Safe disposal of waste – Site selection for landfills – Characterization of land fill sites and waste – Risk assessment – Stability of landfills – Current practice of waste disposal – Monitoring facilities – Passive containment system – Application of geosynthetics in solid waste management – Rigid or flexible liners.


UNIT III

TRANSPORT OF CONTAMINANTS      

8

Contaminant transport in sub surface – Advection, Diffusion, Dispersion – Governing equations – Contaminant transformation – Sorption – Biodegradation – Ion exchange – Precipitation – Hydrological consideration in land fill design – Ground water pollution.

UNIT IV

WASTE STABILIZATION         

10

Stabilization - Solidification of wastes – Micro and macro encapsulation – Absorption, Adsorption, Precipitation – Detoxification – Mechanism of stabilization – Organic and inorganic stabilization – Utilization of solid waste for soil improvement – case studies.

UNIT V

REMEDIATION OF CONTAMINATED SOILS

9

Exsitu and Insitu remediation-Solidification, bio-remediation, incineration, soil washing, phyto remediation, soil heating, vetrification, bio-venting.

TOTAL : 45 PERIODS

OUTCOMES:The students will be able to
• Assess the contamination in the soil
• Understand the current practice of waste disposal
• To prepare the suitable disposal system for particular waste.
• Stabilize the waste and utilization of solid waste for soil improvement.
• Select suitable remediation methods based on contamination.
