This course covers the chemistry and biology associated with water and wastewater treatment labs.  Laboratory exercises carried out at nearby water and wastewater treatment plants are the focus of the course.  These labs teach the student to perform common tests such as those for pH, color, turbidity, dissolved oxygen, and bacteria.  Online lessons supplement the lab work by introducing the student to biological and chemical theory.

Where do I start?

ENV 110 is a prerequisite for ENV 211.  Before starting on this course, you need to review the lessons from ENV 110 .

After reviewing ENV 110, we recommend that you start out by browsing this site to find out what's here.  Read over the Course Syllabus.  Then start reading through the Lessons, which walk you through the information.  You may also want to browse through the Topics, which give short summaries of subjects introduced in the course and are useful references.

To take the course for credit, you must register with Mountain Empire Community College.  Once you feel comfortable with the information, begin the registration process.  (You will still have to fill out the appropriate forms for MECC.)   Please read the entire tutorial and follow the instructions.

After registration for this course, you must complete the initial assignment within one week of entering the class.  If the initial assignment is not completed you will be administratively withdrawn from the course.  You may either complete the assignment online and submit it to the instructor, or print the assignment and mail or fax it to the instructor.  Contact information is given under the Instructor tab.


Purchase your texts:

The required textbook for this course is the AWWA's Standard Methods for the Examination of Water and Wastewater.  This textbook can be viewed at any local water treatment plant. 

Alternatively, you can purchase the text through the MECC Bookstore (located in Goodwin Hall).  You may purchase texts in person or by phone at (276) 523-7461.  Checks or money orders should be made payable to the MECC Bookstore.  Charge cards are accepted.  Books can be shipped to your home or office, but there is a shipping charge.  When purchasing materials, please make the bookstore aware that you are enrolled in distance education courses.

How the Lessons Work:

We recommend starting with Lesson 1 and working through the lessons in order.  Some lessons will have a reading assignment, which is listed at the beginning of the lesson and in the Course Syllabus

After completing the online lesson and textbook reading, you should complete the assignment and take the lesson's quiz.  Both of these are self-grading so that you will know your score immediately.  You can re-take the assignments and quizzes until all of your answers are correct.

The course also has a midterm and a final exam.  All quizzes and tests are open book and open notes and focus on the material presented in the lessons, but can include information from other portions of the course.  More information on testing procedures.


In this course, you will perform several Labs at water and wastewater treatment plants.  These labs are the primary focus of the course.  You should read over the laboratory procedure and any introductory material carefully before performing each lab. You will be asked to Visit at least two water treatment plants and two wastewater treatment plants as part of the course.
