Course Description

This course explores principles of water purification including pretreatment, aeration, coagulation, flocculation, sedimentation, filtration, disinfection, fluoridation, softening, stabilization, taste and odor, and the distribution system.  In addition, the course includes labs completed at a local water treatment plant and an introduction to water treatment math.




Since ENV 115 is an online course, each student is expected to check his or her Mountain Empire email address at least twice weekly.  If you are having problems using your Mountain Empire email address, please contact the instructor as soon as possible. 

The instructor will use email to keep you updated on your progress throughout the course.  If you have completed any kind of assignment and have not heard from the instructor within a reasonable length of time (two work days if the assignment was turned in over the internet or a week if the assignment was turned in through the postal service), then you should contact the instructor to make sure that your assignment was received.



Reading Assignments

The student will need to read the online lessons as well as selected readings in the textbooks.  The chart below lists each week's reading assignment.  Tests include information both from the online lessons and from the textbook readings. 



Other Assignments and Information

Most lessons have an associated question set or math assignment which should be completed after studying the lesson.  The quizzes and assignments are a way for you to test your knowledge of the information, so you should complete them after studying the lesson.  You may take each quiz as many times as you wish before the due date --- I will use your highest grade on each quiz.

In addition, there are four labs and two exams which need to be completed during the course of the class.  The exams must be proctored .  You should decide where you want to take your exams within the first three weeks of the course and give your instructor the proctor information. The exams are NOT OPEN BOOK.

All assignments which are not self-grading may be emailed or mailed to the instructor. 

The chart below lists the assignments which should be completed each week.
