[30], Chief Justice of Ontario Dennis O'Connor's later report on the event concluded that by May 19, Koebel was aware that the May 15 testing of water in the Walkerton system had returned results that indicated contamination, and his action to flush the system with heavily chlorinated water from Well 7 on May 19 was taken in the hopes of eradicating the contamination before further tests could be conducted.

King City Heritage and Cultural Centre Permeable Parking Lot, North Carolina Department of Transportation. An inquiry, known as the Walkerton Commission led by Court of Appeal for Ontario Associate Chief Justice Dennis O'Connor, wrote a two-part report in 2002. Earl returned to the MOE with these documents and reviewed them, noting the May 17 testing results, but notified no one else of these results. [27], SAC employees, in response to this information, contacted the Walkerton PUC the same day for information on possible adverse water testing results.
He destroyed the previous version of the document and created a new one with fictitious data: the new document showed Well 7 as not having operated on the days it had actually been pumping unchlorinated water into the system, and contained chlorine residual records for Well 7 which were entirely fictitious. Hospitals in two neighbouring towns had each seen one case of bloody diarrhea. Included in this documentation were records of the May 17 adverse testing results of May 15 samples from the "Highway 9" water main construction; excluded was pumping history for Well 7. Commissioners also failed to review whether Koebel was performing these aspects of his job adequately. Another unexpected finding was the impact the sound of helicopters had on many people "as iconic of the sickness,'' the study found. MAPLE LEAF CASE STUDY: AN EXAMPLE OF CRISIS MANAGEMENT By Colin P. Stevenson (plaintiffs' counsel) ... the Mayor of Walkerton was quoted as follows: "Governments should have learned from the mistakes that led to the tragedy in Walkerton.
Nevertheless, a 1998 inspection verified that eight or nine samples were still the standard of collection in Walkerton. [24] During later investigations of the outbreak, experts on the Walkerton Commission Expert Review Panel determined that the manure-contaminated water had likely seeped into the aquifer that underlay Well 5, though it may have been possible that surface runoff, rather than contaminated groundwater, was the source of the bacteria. [6], As a result of their lack of formal training and their overseeing themselves, the Koebel brothers were relatively uninformed about water safety. [39], Authorities from the Ontario Clean Water Agency took over operations at the Walkerton Public Utilities Commission on May 25 at the request of Mayor Thomson. Students working in groups, are asked to research and briefly report on the events surrounding the Walkerton tragedy of 2000, when an outbreak of E.Coli in the water supply led to the deaths of 7 residents, and left 2300 seriously ill. 2. The same day, Koebel returned Well 5, which had not been feeding Walkerton's water supply since May 15, to service.
Public Utilities Commissioners should have been responsible for hiring and maintaining informed and capable PUC staff, beginning with senior management; Commissioners relied on PUC manager Stan Koebel to make policy and inform the Commission of water quality-related events of interest, even when commissioners were or should have been aware of such information and responsible for policy-setting. [30] The samples were received by the London Regional Public Health Laboratory at 12:45 a.m. on May 22; a further round of sampling was ordered to be done the next day. [7] Neither man had formal training in public utility operation or in water management, but by 2000, both had been promoted to management positions on the basis of their experience.

[27] The well was then turned off at 1:15 a.m. on May 21. Requests were placed with the Ministry of Health for an epidemiologist and for staff to assist in treating Walkerton-region gastroenteritis patients; public health staff began looking into acquiring equipment that would be needed to treat any E. coli patients whose infections progressed to Hemolytic-Uremic Syndrome (HUS). They must develop and express their own ideas based on gathering information in short background readings and internet research.
[25] After speaking to public health officials that day, Stan Koebel (PUC manager) began the process of flushing the system and increasing chlorination levels, procedures he described to David Patterson as "precautionary". [19], In the spring of 2000, Walkerton's system typically drew most of its water from one well at a time, alternating unevenly between wells 5, 6, and 7. That day, the Walkerton Hospital treated seven children suffering from gastrointestinal ailments involving cramping and diarrhea. The study concludes that most people in Walkerton were affected in some way by the crisis and that many still suffered some effects two years later. By May 20, the Walkerton hospital had fielded calls from more than a hundred people about incidences of gastroenteritis in the town, and attended to dozens more in their Emergency Department.
As a result, one key lesson to emerge from the tragedy is that a "multi-faceted approach to the provision of warnings'' should be in place in any emergency-preparedness plan. [33], At 9:45 on the morning of May 23, David Patterson (the Assistant Director of Health Protection at BGOSHU) contacted Stan Koebel at the Walkerton PUC and informed him of the May 21 test results. �� PK ! Koebel, in his verbal interview with Earl, failed again to provide information about adverse water testing results and other potentially crucial system information; he informed Earl that Well 7 has had a new chlorinator installed, for example, but omitted mention that this had been after the well had pumped unchlorinated water into the system for days.

A quick overview of the past is given, as students focus on what is being done presently and since the Walkerton tragedy. However, as the outbreak grew in severity the two were eventually part of the criminal investigation into the incident, and, as a result, both would eventually plead guilty to a charge of common nuisance through a plea bargain. 6�i���D�_���, � ���|u�Z^t٢yǯ;!Y,}{�C��/h> �� PK ! [29], Excerpt from May 20th telephone conversation between Stan Koebel, of the Walkerton Public Utilities Commission, and Christopher Johnston, of the Ministry of the Environment. [15], May 15 water testing on the Highway 9 water main construction project in Walkerton returned positive results for fecal coliform and E. Ecoraster was installed directly on the Clearstone base. [33], Later in the afternoon, Thompson and the council convened a private meeting without BHOSHU staff to decide their next steps. The Walkerton E. coli outbreak was the result of a contamination of the drinking water supply of Walkerton, Ontario, Canada, with E. coli and Campylobacter jejuni bacteria. The Walkerton hospital received its notification at 3:30 p.m. that day. [8] April 2000 sampling done on water from Wells 5 and 6 showed fecal coliform present in Well 5's water, both raw and treated, but not in Well 6's. [13] The PUC's evaluation of chlorine residual levels was typically performed weekly, rather than daily, and actual testing was often eschewed in favour of visually inspecting the "bubble" on the chlorinator for a "guesstimate" of the residual.
[33][35], The Walkerton hospital hosted a roundtable at 1 p.m. the same day to inform local physicians of proper treatment for E. coli O157:H7-associated gastroenteritis, especially with regard to infected children, who were at increased risk for renal failure due to Hemolytic-Uremic Syndrome. [45], The Ontario government of Mike Harris was also blamed for not regulating water quality and not enforcing the guidelines that had been in place. Multiple subsequent tests on the well between 1979 and 2000 continued to conclude that due to the shallow depth at which Well 5 was drilled and the tendency of its water level and makeup to be directly affected by surface runoff, caution toward contamination levels in the well was advisable. Poor- there are no assessment tools given. Another one in four said they were fearful of their future health prospects and almost as many said they were still angry over the outbreak. Case Study – Walkerton’s Tragedy First read the background section individually. This resource is available for download in PDF or word processor format. The tragedy that occurred in the town of Walkerton, where several people died and many more were made very sick by the presence of E. coli bacteria in the municipal water supply, is not only an important and ongoing news story but is also a case study for resource management at the most fundamental level, in the local municipality. The following tool will allow you to explore the relevant curriculum matches for this resource. A 6” base of ¾” Clearstone/type 57 gravel was then installed and leveled.
The Ecoraster E40 was selected for this project. The Walkerton Public Water System….. Send us water facts for our Water Facts of the Week.
