Abstract:
The Field Training Center of the Missouri SmallFlows Wastewater Research/Traing Center was developed to train onsite wastewater professionals through real life,
"hands-on" examples of various wastewater technologies. In recent years the Training Center has been utilized for an end of the semester field trip in the introductory soil science course to demonstrate the combined fundamentals of physical, chemical, and biological principles and associated soil properties relative to wastewater treatment and dispersal. Demonstrations of physical properties
involve saturated flow with gravity versus unsaturated flow with drip irrigation dispersal and the application of Stokes Law with settlement in septic tanks.
Biological and associated chemical properties such as anaerobic, aerobic, and anoxic examples in wastewater treatment with septic tanks, aerator units, and biofilters; microbial diversity and numbers in soil and sewage;
nitrification/denitrification processes; and biochemcial oxidation demand can be demonstrated and related to various soil and environmental settings. Student
evaluations of the laboratory field trip have been extremeley positive relative to the application of soil science to an environmental setting, demonstration of soil
properties in field applications, and making students aware of career opportunities not previously considered by them.
