ENVE554 "Groundwater Remediation" introduces students to science and engineering concepts related to subsurface contamination, the transport and fate of contaminants in the subsurface, and processes for remediation of contaminated aquifers. The course consists of lectures, homework, field trips, field exercises, and computer laboratories. The students learn to use public domain computer codes for subsurface transport and remediation. The students do field exercises at the local Evanite Site. The course includes a Capstone Design Project where student groups work on the remediation design for a contaminated site. Reports on real contaminated sites, supplied by CH2M Hill, a local consulting firm, are used in the Capstone Design Project. I also developed a course reader for the course.
ENVE 535 "Hazardous Waste Remediation" introduces the students to physical and chemical processes for the treatment of hazardous wastes. The course consists of lectures and computer laboratories. The students learn innovative processes for the treatment of waste waters, contaminated air, and soil. The students do a project of designing an ex-situ treatment system. Students taking ENVE 535 join students from ENVE 554 in the group project.
ENVE431/531 "Fate and Transport of Organic Chemicals in the Environment" introduces the students to physical, chemical, and biological processes, controlling the fate and transport of organic contaminants in the environment. Students in ENVE 531 do a project to determine the fate of a contaminant in the environment for a real world contamination incident. The course was developed in the fall of 1995.
