Objectives:

This course will provide the student with quantitative analytical methods for evaluatingchemical reactions in aqueous systems. The student will master the principles ofchemical equilibrium and acquire an elementary knowledge of reaction kinetics,concepts of organic chemistry, and biochemical processes that are important toenvironmental engineers. Upon completion of this course, students will be able to applyacid-base, precipitation-dissolution, complexation, and oxidation-reduction concepts toanalyze water quality problems in natural or polluted enviromnents or assocated withunit processes common to water and wastewater treatment facilities.

Content overview:

This course introduces students pursuing the environmental option in civil engineering toimportant chemical processes that occur in water. This material gives students afundamental ability to mathematically analyze important chemical processes that occurin water and wastewater treatment plants and many natural environments. Chemicalequilibrium analysis is emphasized using conservation of charge and mass principles.Laboratory exercises are included to reinforce chemical behavior and acquaint studentswith common methods for characterizing water quality.

Required skills:

A fundamental knowledge of chemistry is required (CHEM 25). Basic mathematicalskills are required to solve algebraic equations simultaneously and integrate simplekinetic rates expressions. Most computations are performed by hand. Computerspreadsheet software is used for laboratory data analysis and plotting.

Policies and Procedures

Examinations

Two tests and a fmal examination are scheduled. All tests are closed-book, however, one page ofhandwritten notes is pennitted. The lowest test grade will be counted with the course average, but only 3/4as much as each ofthe other two midterm grades. The fmal examination is comprehensive.

Midterm tests may not be missed without prior approval or a certified medical excuse. Makeup tests willbe scheduled at a designated time near the end ofthe semester. Makeup tests may be oral and/or written,and will be challenging! Tests missed with instructor-approved excuses will be handled on an individualbasis.

Missing the final examination without a valid excuse will result in a zero averaged· into your grade.

Homework

Unless otherwise specified, homework assignments will be turned in on an individual basis. Useengineering paper, write with pencil on one side only, provide a problem statement, and box your finalanswer. Staple your homework pages together (folded comers will be rejected) and be sure to include theassignment set number, and the date. Homework will be assigned each lecture and is due in two lectures(e.g., an assignment given on Wednesday is due the following Monday). All homework must be submittedto receive a passing grade ..

Laboratory Reports

Instruction handouts will be available on Monday before the weekly laboratory sessions. You will be heldresponsible for reading and understanding the laboratory prior to your session. Prelaboratory quizzes maybe given without notice. Student groups that have read and understand the instructions generally finish inhalf the time required by poorly prepared groups.

Laboratory exercises will be conducted and reports completed with your lab partner(s). Each group willsubmit a single report one week after completion of the experimental portion of the lab. Reports are to beconsistent with the Civil Engineering Department format unless otherwise specified ..

Make sure that the cover page of your lab report contains the name of the group leader, all participatinggroup members, and the group name. If a student's name appears on a lab report, it certifies that he/shehas participated in the lab report and understands the material in detail. Students may be randomlycalled upon in lab to demonstrate their knowledge. All reports must be submitted to receive a passinggrade in the class.

GradingA weighted average grade will be calculated as follows:Homework

LaboratoryProject (i.e., acid mine drainage)Midterm testsFinal exam

20%20%10%30%20%

Letter grades will be assigned according to overall weighted average scores for the course: 90 IS

guaranteed an A, 80 a B, 70 a C, and 60 at least a D.

A penalty of 50% for each day of lecture past the due date will be imposed on late submissions. All workmust be completed and submitted to receive a passing grade.
