Detailed Description of Conduct of Course
The course will be primarily lecture in format. The course does not have a laboratory component, but there will be classroom demonstrations and field trips to a landfill, a wastewater treatment facility, and possibly to local industries. Since there is a certain amount of controversy surrounding many environmental topics, there should be more classroom discussion than in most other chemistry courses. Although there will be some mathematical problem solving, the course will not be as problem-intensive as general chemistry. Most of the student's time will be used in reading the textbook and articles selected from newspapers and periodicals. A considerable amount of time will be devoted to the discussion of articles within a day or two of their appearance in a newspaper or a widely-read non-scientific publication such as Time. A typical test will involve a few mathematical problems, some short-answer questions, and questions which require the discussion of a particular environmental issue. The only audio-visual materials utilized will be the overhead projector and TV/VCR. One paper dealing with an environmental disaster will be required.

Goals and Objectives of the Course
Having successfully completed this course, the student will be able to:
appreciate the complexity of environmental problems and recognize some of the technological, economic, and political obstacles that must be overcome before they can be solved.
Assessment Measures
Assessment will be based upon weekly quizzes, three or four tests, the paper, and classroom participation.
Other Course Information
"This book is about environmental issues and the chemistry behind them. It is not a methods book, nor is it a catalog of pollutants and remediation options. It aims to deepen knowledge of chemistry and of the environment and to show the power of chemistry as a tool to help us comprehend the changing world around us."
