FREDERICTON - University of New Brunswick researchers say shale gas fracking should not proceed in the province unless an environmentally sound option is found for the disposal of wastewater.
Four professors at the university have released an opinion paper that examines the potential impact on the province's water resources if gas exploration companies begin fracking.
The process involves pumping water and chemicals into a gas well to fracture rock layers and release trapped pockets of shale gas.
The professors say companies should not be allowed to frack until the saline-contaminated wastewater that is forced out of wells can be disposed of in an environmentally responsible manner.
They suggest the companies should consider using carbon dioxide or liquefied propane gas for fracking instead of water.
There has been a strong public backlash to fracking in New Brunswick in recent months.
The provincial government is expected to release new shale gas regulations later this spring.
