Soils and ground water are critical environments specified in Basic Environment Law. However they have been polluted by both natural and anthropogenic contaminants, which cause various environmental problems and deteriorate the natural and built environments. Therefore, risks by such contaminations should be properly evaluated and removed if necessary.
In this course, various aspects on contaminations of ground water and soils, their remediation methods and waste disposal system will be explained: 1) hydrogeology; 2) physics of ground contamination; 3) physical and chemical properties of contaminants; 4) Remediation of ground contamination; 5) waste disposal and containment; and 6) environmental laws and case studies.
Through this course, the students are expected to understand various aspects on contaminations of ground water and soils, such as basic knowledge, physical and chemical principles and theories, and their application on remediation of contaminated sites and conservation of the ground water and soil environment with the consideration of environmental laws. Furthermore the students will learn about various case studies and have their own views on the integrated geo-environment conservation measures and policies.

|✔ Specialist skills||Intercultural skills||Communication skills||✔ Critical thinking skills||✔ Practical and/or problem-solving skills|
Beside the lectures, the group works will be conducted on the environmental problems. Through the group works, suchs as discussion and presentation, the students will learn more about the environmental problems in different natural and built environments and possible solutions on the problems.

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
Handouts on each topic will be provided by lectures.
