In response to a drinking water catastrophe which ended up with seven deaths and illness of one-half of the population of a community in Canada, namely Walkerton, major changes have been imposed to adjust from a reactive to a pro-active strategy to ensure against such circumstances from re-occurring. The regulations now require source water protection planning to be in place. As well, regulations are being upgraded to also require planning for water treatment and distribution, monitoring and alarm systems to be implemented to prevent such occurrences in the future.
