1 CE 341 INTRODUCTION TO ENVIRONMENTAL ENGINEERING SPRING 2017 SYLLABUS UNIQUE NUMBER: INSTRUCTOR: TIME: OFFICE HRS: Dr. Navid B. Saleh Phone: T, Th 9:30-11:00 am Wednesday 9:00-10:00 (ECJ 8.608) or by appointment. PLACE: WRW 113 OBJECTIVES: PREREQUISITES: COMPUTER: TEXT: CLASS FORMAT: COURSE TOPICS: GRADING: This course is designed to introduce the student to the principles of environmental engineering. Topics include material balances, environmental chemistry, risk assessment, air quality, water quality, and wastewater treatment. Course Description: Quantitative evaluation of the environmental, technical and economic problems involved with the control of air, water and land pollutants. CH 301 and 302 or consent of instructor. Proficiency with computers and familiarity with a spreadsheet program like Excel is expected. The course material will closely follow Environmental Engineering: Fundamentals, Sustainability, Design (2009) by J.R. Mihelcic and J.B. Zimmerman. Wiley, ISBN This can be purchased as an online book ( EHEP html). Course notes, supplemental materials, homework assignments and solutions will be posted on Blackboard. Lectures supplemented with outside reading, homework, exams and a project. See attachments The attainment of the academic goals of the course will be assessed according to the following grading scheme: Homework 10% Project 15% Class participation/professional evaluation 2% Two midterm exams (20% each) 40%

2 Final exam 33% Problems affecting grades should be brought to the professor s attention. The plus/minus system of grading will be employed in this course. 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 his/her own assignment. Using homework solutions from previous semesters is not allowed. Those students who violate this policy will receive a zero score for their entire homework grade. Also, late homework will not be accepted because the solution sets will be posted. Homework must be turned in at the beginning of class, or no credit will be given for the assignment. Typically 3-5 homework problems will be assigned, and each of them will be graded according to the following 5-point scale: Points Description 5 Correct solution, both methodologically and numerically; carefully and thoroughly presented, easy to follow. 4 Correct methodologically, but with minor computational or table look-up errors, leading to erroneous final result. 3 Some conceptual error(s) but correct general approach. 2 Major conceptual errors. 1 Completely missed the point of the problem but made some attempt at a solution. 0 Did not attempt problem. ** The grader will subtract 1 point from the score for a problem that is sloppy or has a lack of systematic presentation. PROJECT: The project will consist of an investigation of water quality on the UT- Austin campus, which will serve as our living laboratory. You will work in teams to collect water samples from campus water sources (either indoor or outdoor) and assess how and why the chemical, physical, and biological quality varies as a function of water source. The project will include the following basic elements: (1) a data-gathering stage (groups will collect water samples and relevant environmental data, such as water temperature, dissolved oxygen, and fecal coliform concentrations), (2) analysis and interpretation of the data including literature review and calculations (as appropriate), (3) preparation of a short paper summarizing your analysis (individual paper) and (4) delivery of a short presentation to the class (group presentation). EXAMINATIONS: There will be two 75-minute examinations and a three-hour final examination. Each examination will be closed book and will be given on the date and time indicated. Missed examinations may be made up only if the reason for missing was illness or some other documented emergency. 2

3 CLASS PARTICIPATION Class participation is an important component of the course, and it contributes to your overall grade. Class participation means not only speaking during class, but it also means communicating effectively (i.e., speaking loudly and clearly). SCHEDULE: Event Date* Exam 1 Tuesday, February 21 Exam 2 Tuesday, April 04 Final Exam TBD *Exams will take place no earlier than the dates noted above. EVALUATION: DISHONESTY: ATTENDANCE: An evaluation of the course and instructor will be conducted at the end of the semester using the approved UT Course/Instructor evaluation forms. Don t do it. Students who violate University rules on scholastic dishonesty are subject to disciplinary penalties, including the possibility 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 scholastic dishonesty will be strictly enforced. For further information, visit the Student Judicial Services web site and the General Information Catalog information at utexas.edu /catalogs/gi08-09/app/gi08.appc03.html#chapter-11-studentdiscipline-and-conduct. Regular class attendance is expected in accordance with The University's General Information catalog and the College of Engineering policy (see the section on Attendance in the Undergraduate Catalog). While attendance will not be used directly to assess the course grade, material covered only in the lecture may be included on the exams. Also, the professor will not repeat material for students who miss class without a valid reason. Occasionally, a student might be able to earn extra points during classroom activities; these extra points will not be available to students who miss class without informing the professor of a valid reason for their absence BEFORE class. RELIGIOUS HOLIDAYS: A student who misses classes or other required activities, including examinations, for the observance of a religious holy day should inform the instructor as far in advance of the absence as possible, so that arrangements can be made to complete an assignment within a reasonable time after the absence. 3

4 PRIVACY ISSUES: DISABLED STUDENTS Web-based, password-protected class sites will be 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 , engaging in class discussions and chats, and exchanging files. In addition, electronic class 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 directory information, see the General Information Catalog or go to: The University of Texas at Austin provides, upon request, appropriate academic accommodations for qualified students with disabilities. For more information, contact the Division of Diversity and Community Engagement, Services for Students with Disabilities, or If a student has academic accommodations that allow the student to test in a reduced distraction environment, it is the student s responsibility to arrange the testing room. At least one week before each exam, the student should confer with the instructor regarding the reservation time and location of the testing room. Other Important Information: From the 1st through the 12th class day, an undergraduate student can drop a course via the web and receive a refund, if eligible. From the 13th through the university s academic drop deadline, a student may Q drop a course with approval from the Dean, and departmental advisor. 4
