Walkerton Case Study
In May 2000, a waterborne disease outbreak occurred in Walkerton, Ontario. Over 2,300 people became ill and seven people died as a result of E. coli 0157:H7 and Campylobacter jejuni contamination in their drinking water. An inquiry was called to determine how the water had become contaminated and if charges should be laid against those directly involved with the treatment of water.
