Given that little is known about the long-term integrity of concrete seals and steel casings in 600,000 abandoned hydrocarbon wells in Canada, the study stated that the oil and gas industry’s future impact on groundwater could be immense. The report concluded that unconventional natural gas drilling such as coalbed methane (CBM) poses a real threat to groundwater quality and quantity, and that the nation needs “baseline hydrogeological investigations…to be able to recognize and track groundwater contaminants.” [Emphasis added]
