This course is the third of a four course series in the contaminated site technical studies. It introduces the student to the third major process in contaminated site management: site investigation and risk assessment. Focusing on the role of the site investigator, the course promotes a scientific approach for evaluating and selecting options to manage site contamination, including treatment, removal or containment. Building on the site investigation data from EENG 8270 - Contaminated Site Investigation Process, this course focuses also on the toxicological principles of risk assessment, and on the evaluation and design processes for site remediation. The second half of this course focuses specifically on the range of remedial technologies that are available and provides students with the skills to apply appropriate technologies in given situations. Discussions on the techniques to monitor and evaluate performance of the selected remedial options are also included. Since this is the final course in the series, this course also focuses on integrating the material from the previous courses.
This course is reserved for Environmental Engineering Technology Degree program. Students will require department approval prior to registration. Please contact Program Assistant at email@example.com or call 604-432-8539.
