Office Hours: By appointment
The focus of this course is the use of treatment wetlands and phytoremediation technology to clean up contaminated environments. The course will introduce graduate or senior-level undergraduate students to basic concepts and principles on the hydrological, biogeochemical, and ecological processes, and the development of different treatment wetlands and phytoremediation systems. Various case studies will be given to illustrate the application of the remediation technologies in the cleanup of different polluted environmental substrates, including inorganic and/or organic contaminants in water, sediment, or soil. Students will have opportunities of conducting research projects during the course of study.
1) To introduce major remediation functions of treatment wetlands and phytoremediation systems for cleanup of different contaminated substrates;
2) To examine the mechanisms of different remediation processes; and
3) To discuss the criteria of system-design, establishment, operation, and management for safe and effective application of treatment wetlands and phytoremediation technology.
A basic understanding of biology and general ecology is required.

Class exams: Material presented in class lectures and required readings will form the basis for examination questions. Class examinations will require an understanding of lecture and reading materials, and result in applications of the knowledge to practical situations. One research project will be presented.
Grading: A: 90-100; B: 80-89; C: 70-79; D: < 70. Total points: 100, including two midterm exams: 60% (30% each); Research presentation: 10%; final exam: 30%.
Regular prompt attendance is required for success in this course. Only University approved absences will be accepted. Because classroom or group discussion will form an important part of class lectures, excessive absences may result in a 10% reduction of your overall grade or your being dropped from the course.
"The University gives high priority to matters of academic ethics and abhors all types of cheating, including plagiarism. Plagiarism is the act of representing the work of another as one’s own and may consist of copying, paraphrasing, or otherwise using written or oral work of another without proper acknowledgement of the source or presenting oral or written material prepared by another as one's own.” (SIUE Summer 2003 Class Schedule, p. 13).
In the event of academic misconduct, the student is subject to a number of penalties, including a failing grade for a plagiarized assignment or for a course.
Students with Disabilities
Students with disabilities should visit the Disability Support Services (DDS) located in the Student Success Center, Room 1270, at their earliest convenience to meet the director and discuss available services. The student with a documented disability and a disability ID card from DSS should also notify the instructor as soon as possible to make any necessary arrangements.
