Examples of Required Writing Assignments

Respond to a written prompt such as:
While operating a conventional surface water treatment plant during a large rainfall event you notice that your influent turbidity has drastically changed. The influent turbidity has jumped from 1 ntu to 30 ntu's, the water temperature has jumped 5 degrees and your filters are becoming unstable. What effects will this have on the process? What actions would you take? What regulations would you need to be aware of?
