More than 25% of Canadians rely on ground water for their drinking water supply. Many instances of waterborne illnesses are attributed to groundwater sources that were considered safe and became contaminated by pathogens (e.g., Walkerton, ON, May 2000). These disease outbreaks are not randomly distributed; rather they are more likely to occur in fractured rock aquifers. In Canada, 70% of the regional aquifers occur in fractured bedrock, and it is common practice to hydraulically fracture (frack) these aquifers to increase the water yield. This practice can further increase the vulnerability of these aquifers to pathogen contamination due to the induction of hydraulic connections between the aquifer and ground surface.

超过 25% 的加拿大人依靠地下水作为饮用水供应。许多水传播疾病的实例都归因于被认为安全的地下水源却被​​病原体污染（例如，安大略省沃克顿，2000 年 5 月）。这些疾病的爆发并不是随机分布的；相反，它们更有可能出现在裂隙岩石含水层中。在加拿大，70% 的区域含水层存在于裂隙基岩中，通常的做法是对这些含水层进行水力压裂（压裂）以增加产水量。由于含水层和地表之间存在水力连接，这种做法会进一步增加这些含水层对病原体污染的脆弱性。
