After a significant public outcry against the practice, the Government of Nova Scotia has launched a review of the rules and regulations of hydraulic fracturing.
Hydraulic fracturing is a controversial technique for extracting methane from shale deposits. Oil and gas companies drill wells and pump in a mixture of fresh water, sand and toxic chemicals to crack apart shale and release the captured methane. Some of the fracking fluid returns to the surface but much of it is lost underground. Hydraulic fracturing, or fracking, has been associated with the contamination of groundwater and water wells as well as other health and environmental impacts.
The review will be led by staff from the departments of energy and environment. The review addresses concerns around water exclusively. The public has been invited to provide comments on the review process and the window for comments closed June 6.
However the limited focus on water leaves out a number of other impacts of fracking:
Air Quality
Storing shale gas at drill sites involves the release of volatile organic compounds which reduce air quality locally. In some cases, rural areas have worse air quality than smoggy cities. Worse still, the haze caused by fracking has been associated with creeping brain damage and other impacts as documented by Dr. Theo Colborn.
Climate Change
The province and industry trumpet shale gas as a clean alternative to coal. It produces less greenhouse gas emissions per unit of energy than coal. But a robust review would assess whether these claims are accurate. A full lifecycle analysis of fracking as undertaken by Robert Horwath of Cornell University would provide a clearer picture.
Tourism
Nova Scotia has invested heavily in the tourism sector. Rural areas especially rely on visitors from out of province as a source of economic development. As drill rigs and condensate tanks spring up...
