Suggested project
Case Study - Walkerton
In 2000, the water supply at Walkerton (Canada) became contaminated with a dangerous strain of e-coli.
Prior to the outbreak, there was significant rainfall from a dairy farm adjacent to a well. The well had been
known to be prone to contamination.
As a result of the contamination, seven people died and about 2,500 people (from a town with a population of
5,000) became ill.
