Even now, after several reviews of fracking in this country, we aren't certain what it's doing to our air and water.
One such review, conducted by the Council of Canadian Academies (CCA), discovered the body of research into hydraulic fracturing was incomplete - there were no reliable studies on the environmental impacts.
There were reports of people lighting their tap water on fire and gas wells leaking methane into the atmosphere, but for all the panel's efforts, they couldn't deliver anything conclusive. The research simply hasn't been done.
In their conclusion they say, "authoritative data about potential [environmental] impacts are currently neither sufficient, nor conclusive."
