A new machine will be used to solve one of the more contentious mysteries of coal seam gas extraction - how it will affect underground water supplies.
The unique centrifuge, to be used by researchers at the University of NSW, takes clay samples from the walls of underground aquifers and subjects them to extreme pressure.
The movement of water contained in the clay allows researchers to mimic the long-term changes in underground water and estimate how quickly any contamination caused by a gas well would spread. Read More
