Any problems, personal or otherwise, affecting grades should bebrought to the instructor's attention.

HOMEWORK POLICY: This course will stress cooperative learning. There will be a

number of homework assignments during the semester. On most

assignments and unless otherwise stated you may work in groups.However, each student must turn in their own assignment. Using

homework or homework solutions from previous semesters is not

allowed.

will be given in class on the date indicated. The exams will coverlecture material and assigned reading material. A class crib sheet

will be prepared prior to the exam and distributed with the exam.

Missed examinations may be made up only if the reason for

missing was illness or some other emergency. The final exam willbe given as scheduled by the registrar.

EVALUATION: The University Measurement and Evaluation Center forms will beused in the last week of class to evaluate the course and instructor.

DISHONESTY: Dont Cheat. Students who violate University rules on scholastic

dishonesty are subject to disciplinary penalties, including thepossibility of failure in the course and/or dismissal from the

University. Since such dishonesty harms the individual, all

students, and the integrity of the University, policies on scholasticdishonesty will be strictly enforced. For further information, visit

the Student Judicial Services web site

ATTENDANCE: Regular class attendance is expected in accordance with The

University's General Information catalog and the College ofEngineering policy (see the section on Attendance in the

Undergraduate Catalog).

PRIVACY ISSUES Web-based, password-protected class sites are associated with all

academic courses taught at the University. Syllabi, handouts,assignments and other resources are types of information that may

be available within these sites.

Site activities could include exchanging email, engaging in class

discussions and chats, and exchanging files. In addition, electronicclass rosters will be a component of the sites. Students who do not

want their names included in these electronic class rosters must

restrict their directory information in the Office of the Registrar,

Main Building, Room 1. For information on restricting directoryinformation, see page 7 of the Course Schedule or

http://www.utexas.edu/student/registrar/catalogs/gi00-

IMPORTANT NOTE: The University of Texas at Austin provides upon request

appropriate academic adjustments for qualified students with

disabilities. For more information, contact the Office of the

Dean of Students at 471-6259, 471- 4241 TDD or the College of

Engineering Director of Students with Disabilities at 471-4382.

Class Project

You must locate and discuss an article or chapter from a newspaper, journal or book that deals

with an environmental issue. The article must be from 2008. You may work alone or in groups

of two. You need to turn in a one to two page paper discussing your topic and provide a fiveminute summary to the class. Your discussion will focus on:

1. Contaminant Properties (physical/chemical/biological)2. Health concerns3. Sources of contamination4. Major locations of contamination5. Fate of the contaminant in the environment6. Routes of exposure7. Major incidents of exposure8. Treatment processes or remediation techniques9.

Regulations and legislation that pertains to the contaminant10. Economic, social and ethical implications of use, replacement, or banning of thecontaminant

In your research, I do not intend for you to report on each of the ten items above, however, the

class discussion will attempt to cover all of them.

Potential topics include:

1. Arsenic drinking water standard2. Perchlorate drinking water standard3. Teflon in cooking4. Fluorescent Light Bulbs5. Carbon Trading6. Renewable Energy7. Ethanol Fuel8. Endocrine Disruptors9. Ground Level Ozone10.Second Hand Smoke11.Sediment Capping12.Ozone Generators Sold as Air Cleaners13.Nuclear Power14.Noise Pollution15.Nanoparticles in the environment16.Antibiotics in the environment17.Environmental Impacts of Outsourcing18.Alternative Engineering Solutions to Traffic Congestion19.Eco-Friendly Diapers20.Sustainable Farming21.Fresh Water Shortages
