Lesson 3: Disease-Causing Microbes

Lesson 3: Disease-Causing Microbes

The students will investigate five common diseases that can be transmitted by water by becoming the experts on a particular disease. Each learning centre will have information to read and questions to answer. After learning about the disease, each group of students will present their information so that the whole class can learn about the disease.

Milwaukee Case Study

Milwaukee Case Study

Milwaukee receives its water from Lake Michigan. The origin of the contamination was found to be sewage that passed through the plant’s filtration system. Where the sewage came from is still unknown but it might have been run off from a farm or feed lot.

North Battleford Case Study

North Battleford Case Study

In March 2001, the solids contact unit in the surface water treatment plant was emptied and all the sludge removed from the bottom in order to inspect, clean and repair a crack that had formed in the cement floor. This type of repair should normally be done in February, so that the spring breakup and runoff will not affect the system.
