COURSE CONTENT

Student Learning Outcomes:
Upon completion of the course, students will be able to:
Untitled document
1.  Implement quality assurance and safety procedures while performing chemical and biological
    tests used in water/wastewater testing laboratories.
2.  Apply chemical and biological concepts when performing laboratory tests.
3.  Make necessary mathematical calculations required in water/wastewater laboratory testing.

In order to achieve these learning outcomes, during the course the students will:
1. Apply an understanding of basic water and wastewater chemistry to treatment processes.
2. Demonstrate safe use and proper care of laboratory equipment.
3. Define and identify types of samples collected for water and wastewater testing processes.
4. Analyze and determine if proper levels of water and wastewater treatment have been
    achieved.
5. Perform laboratory tests for pH, Dissolved Oxygen, Solids (settleable, suspended, total, and
    volatile), Sludge Volume Index, Biological Oxygen Demand, Chemical Oxygen Demand,
    Alkalinity, Hardness, Turbidity, Jar Testing, Free and Total Chlorine Residual, Total
    Suspended Solids, and Mixed Liquor Suspended Solids.
