Walkerton Tragedy

In May 2000, seven residents of Walkerton, a small town in southern Ontario, died of E. coli poisoning transmitted through the town’s water. The water had been drawn from a well that was usually a safe source of water supply. Although well water treatment was rather simple—just added chlorine to disinfect it—the town water works’ manager, Stan Koebel, believed that the water was so safe that chlorine did not have to be used.

This conclusion may have been true under normal circumstances; however, during April 2000 the farm adjacent to the well fertilized its fields with cattle manure. Unfortunately, during the second week of May, the area received unusually high levels of rain, which washed E. coli from the manure into the well. The usual level of chlorine was inadequate to kill the high level of the bacteria. Compounding this, Koebel did not follow the Ontario Ministry of the Environment’s guideline for checking the level of residual chlorine in treated water (in fact a minimum of .5 mg per litre should remain to continue disinfecting the water through the distribution pipes).

During the third week of May, people started to get sick. Water was finally tested and E. coli was found in the samples. Koebel kept quiet for a few days, hoping the nightmare would end. Unfortunately, the situation got worse: almost half the town’s population got sick and eventually seven people died.

Question:

  1. Prepare an HACCP analysis to develop a quality management system for water treatment of such a town.

Axel Pine is a sales representative. Axel is dealing with a challenging customer and needs support from their Sales Manager, Francesca Liet. He wants guidance on how to approach and solve a complex customer request. Axel has sent three emails to Ms. Liet in the past two weeks and has received no response. He is getting very frustrated.

The Email Trail

Email 1

Hi,
I just wanted to let you know that I am having a difficult time with Bosrox Manufacturing. They are making demands above my pay grade.
Axel

Email 2

I hope the conference in Regina went well for you. I know how demanding the trade show floor can be. To fill you in on Bosrox. They are asking for a break in shipping costs per order and I think they are probably worth it given how much business they have provided us in the past. Last month I had lunch with their purchasing manager who I play golf with quite often and he says he is very happy with our services and our costs in general. He said they are not shopping for the business and our account is safe. I have been doing research of my own into possible competitors for our account and I can’t seem to come up with any viable challengers. I think we are ok with Bosrox overall. The reduced shipping request is a puzzling one. I think I will do research on the cost of shipping and what our competitors charge and put together a report to see if the cuts are worth it or not. I hope everything is well with you and that you are getting used to the new role. I am always there to help if you need it. The all-hands meeting next month will be a good opportunity to get together and get to know each other better. I want to help you in any way that I can. Please feel free to reach out to me.
Best,
Axel

I know you are very busy in the new position. Please let me know if I can help. I have not come to a final plan for Bosrox and the shipping price reduction.
Axel

What made Axel’s email incoherent and where did it shift topics? Use specific examples where possible.
