Objective of the course

The course is designed to give the students a broad understanding of all issues related to environmental science, engineering and management, including practical training on pollution monitoring techniques. 

Since the student strength in this course is ~100, lectures should only be scheduled in larger rooms, i.e., L16, L17 etc. In addition to the lectures, the course has a laboratory component where students get hands-on training (in groups of 2) in environmental quality and pollution monitoring techniques. Laboratory space requirement is 2 m2 per student. Due to space constraints in the Environmental Engineering Laboratory, the laboratory classes are generally held in two sessions per week. Further increases in student strength over the last three years have made the space crunch more acute and the laboratory sessions may have to be held for 3 sessions / week in future. This will require enhanced faculty and staff involvement. Additional TAs must also be assigned to the course. The current yearly funds requirement (consumable purchases) for this laboratory is approximately Rs. 4000 per student. Funds for equipment purchase are also required on a yearly basis.
One hour per week laboratory instruction is required. Therefore, the 3 laboratory hours will be broken into 1+2. The instructions for the laboratory sessions would be given to the students in the first hour followed by the laboratory experiments.
