(OilPrice) One of the major North American energy success stories over the past decade has been the massive rise of U.S. natural gas production as a result of the hydraulic fracturing process, increasingly referred to in journalistic shorthand as “fracking.”

The technique is not without its critics, who allege that energy companies a) inject a toxic brew of substances into their boreholes to expedite the procedure, and b) in turn, risk polluting underground water resources and aquifers. Accordingly, as the U.S. government has yet to intervene on regulating the process, a number of states have passed rulings at worst, imposing moratoriums on the procedure, or requiring more data input.

It is a measure of the technique’s success that its usage has now spread north of the border, but the downside for proponents is that Canada’s Quebec province has banned the procedure for present.
