PHILOSOPHY:
The courseimparts to students thetechnical underpinnings to developsolutionsfortheenvironmental challenges faced by engineers today and provide insight into ways of tackling the emerging issues. The course covers the physical and chemical properties of environmental pollutants, the fate of pollutants in the environment and the principles of various treatment processes. The interdisciplinary knowledge gained in this course will provide attendees witha solid foundation for designingunit processes and making informed decisions as practicing environmental engineers.
ASSESSMENT:
For this 15-point course, 40 marks are allocated to course work:20 to mid-term test and 40 to final exam. The course work consists of three online quizzes (18 marks), three lab reports
(18 marks) and student participation (4 marks).
LEARNING OBJECTIVES:
On the completion of this paper students will be able to:
-Identify the underlying mechanism(s) of environmental impact by pollutants.
-Discuss the principlesofdesign for various treatmentsystems.
-Predict and quantify the effectof environmental parameters on the efficiency of treatment processes.
-Apply fundamentalprinciples to gain an understanding of behaviours of differentenvironmental pollutants.
-Develop a preliminary assessment of the fate of contaminants in the environment.

LABORATORY:
LAB 01: Water Quality – Coliform assessment(WQZ)
LAB 02: Water Quality – Metal complexation (NS)
LAB 03: Soil Contamination – Chemical transport (AS)
All experiments will be conducted in the Environmental Engineering Laboratory (201B) at the time specified in the laboratory schedule distributed during class. All students must attend labs and submit a report for each experiment conducted in the laboratory.
Safety note: students must wear closed-toed shoes (i.e. no sandals or similar footwear). Students will be asked to leave if wearing inappropriate shoes.
