The actual harm to human welfare from hydraulic fracturing (or fracking) is extremely low, finds a new study released today by the Fraser Institute, an independent, non-partisan Canadian public policy think-tank.

“Contrary to popular rhetoric, the risks of fracking can be managed and minimalized in Canada and elsewhere,” said Robert P. Murphy, Fraser Institute senior fellow and author of Managing the Risks of Hydraulic Fracturing, 2020.

The study dispels several myths about fracking and its effects.

Myth #1: Fracking causes earthquakes

In fact, seismic activity—which is typically very minor, causing no damage—related to fracking is not due to the practise per se, but rather wastewater disposal methods, which pump water back into the ground. Research suggests that altering the depth and flow rate of the water injection can minimize the risk of seismic activity.

Myth #2: Fracking systematically contaminates drinking water
