Soil and Groundwater Remediation

Instructors: Evangelos Voudrias
Course Code: ΟΕΑ4ΕΠ
Semester: 9th
Weekly teaching hours: 3
ECTS credits: 5
Prerequisites: Aquatic chemistry, Mathematics-I, Unit operations, Unit processes
Course offered to Erasmus students: Yes
Course URL: TMC291/

Learning Outcomes:  

1. Knowledge based:

  • The objective of the course is to present a quantitative treatment from the design point of view of the most important technologies, used for remediation of soil and groundwater contaminated with hazardous waste. The emphasis is on in-situ technologies.
  • Understanding the behavior of dissolved and non-aqueous phase contaminants in soil and groundwater.
  • Understanding the methodology for risk assessment and remediation of uncontrolled landfills.
  • Understanding the approach to solution of typical environmental problems from mining activities.

General Skills:

  • Following the successful completion of this course, the student will be in a position to evaluate, combine and select the different remediation technologies, which were mentioned above.
  • Ability to compute contaminant transport in subsurface systems.
  • Ability to conduct basic calculations required for preliminary design of remediation technologies, which were mentioned above.
  • Ability to conduct risk assessment calculations for uncontrolled landfills.

Course Content:
1. Solute mass transfer in saturated porous media

5. Pump-and-treat of contaminated groundwater
6. Non-Aqueous Phase Liquids in subsurface systems: Movement and physical-chemical behavior
7. In-situ active walls and “funnel and gate” systems
8. Bioremediation of contaminated groundwater
9. Overview presentation of soil remediation technologies (thermal treatment, physical-chemical treatment, biological treatment, phytoremediation, natural attenuation)
10. Soil vapor extraction
