Hydraulic fracturing poses little threat in contaminating groundwater in New Brunswick, Canada, writes geoscientist Steve McCutcheon. "Furthermore, it is highly probable that any future [fracking] in the province will involve the use of propane rather than water ... because of the nature of our gas-bearing shale, which was originally deposited in a lake, rather than a marine, environment as were most other gas-bearing shales in North America," McCutcheon writes.
