Nova Scotia assesses environmental impact of hydraulic fracturing in oil and gas exploration
The Nova Scotia government Friday published comments from the public on the environmental impact of hydraulic fracturing, also known as fracking, in petroleum exploration.
The comments are part of a joint review, undertaken by the Nova Scotia departments of energy and environment, of hydraulic fracturing in oil and gas operations. The review will consider parameters such as site development, proximity to surface and groundwater resources, plus hydraulic conductivity of soils.
The scope of the review may include the impact of storage and handling of hydraulic fracturing additives.
A summary of the comments is published in the review of hydraulic fracturing in Nova Scotia.
The government also published all comments on hydraulic fracturing in a PDF file on the Nova Scotia government Web site.
Some citizens claimed fracturing will cause pollution while others said petroleum industry is needed to create revenue and jobs. One major area of concern identified by the province is the impact on groundwater. The joint review will assess potential risks to groundwater and water wells.
In a fact sheet published on the Nova Scotia Web site, the province says the department of energy does not have any applications for the use of hydraulic fracturing of shales in Nova Scotia.
The province requires all wells being drilled be cased in steel to ensure nothing put down the well or brought up the well can escape. The steel is then required to be encased in cement.
