  1. Is fracking safe? Air quality

    In the first three posts (parts one, two and three) in our series on the risks of hydraulic fracturing, we have focused on the potential issues that hydraulic fracturing poses to water. We now turn our attention to the risks hydraulic ...

  2. Is fracking safe? Water use

    So far in parts one and two of the this series of posts on the safety of hydraulic fracturing, we have looked at both the overall risk to surface and ground water from unconventional oil and gas activities, as well as the potential for ...

  3. Is fracking safe? Well integrity

    In part one of this series of blog posts, we provided evidence that hydraulic fracturing does not pose systemic threats to ground and surface water. Related to this issue is integrity of the wells, which allow oil and gas to come to the ...

  4. Despite protests, fracking risks are modest and manageable

    Appeared in the Toronto Sun, November 4, 2015 There’s never a dull moment in the debate over the safety of hydraulic fracturing—a process where water, sand, and a small amount of chemicals under high pressure are used to crack open rock formations, ...

  5. Is fracking safe? Surface and ground water

    Canada has a lot to gain from developing its shale oil and gas resources through the use of hydraulic fracturing, a method of extraction where water, sand (proppant) and a small percentage of chemicals are injected under high pressure ...

  6. Managing the Risks of Hydraulic Fracturing: An Update

    Activist groups continue to oppose hydraulic fracturing, a new application of old technologies that is unlocking vast supplies of oil and natural gas in the United States and Canada. This opposition has resulted in the establishment of moratoria in ...

  7. When compared to other procedures, fracking uses relatively small amount of water

    Hydraulic fracturing has unleashed a renaissance of oil and gas production in the United States. The chart below shows American oil and gas production from 1970 to 2014. After more than three decades of declining production, the adoption ...
