Meetings have been held around the region, over the last few months , addressing the planned fracking
“I cannot believe that you can inject significant quantities of highly toxic chemicals into a rock seam at high pressure to fracture the rock
and then flush it out with a large volume of water with-out contaminants being left behind to pollute aquifiers!” All this in a state where
potable water is a serious problem.
Are then any comprehensive maps of Aquifiers anywhere in Australia showing not only their positions but their stratification? What is the
inter-relationship between them and the surrounding rock strata. What are their inter-connections? So many questions are posed and unanswered. It seems to be a case of proceeding on a wing and a prayer!
It could be argued by those in favour that they are only fracking shale and not highly porous rock but how can they be sure that the shale layer
was not fractured by seismic activity at some time in the distant past? This may pose a risk of leakage of the fracking mix into other rock
layers and hence into water bearing or conducting rock. The shale may be intersected by other porous rock. You can’t see this especially as it
may be some distance from the immediate fracking site and be exposed by a fissure produced by the process.
Another concern is the huge amount of water to be used. Where is the contaminated water stored? In clay pans? How is it decontaminated? Is
it through evaporation which then leaves behind a toxic sludge? If so what prevents the toxic dust being blown about over surrounding land?
What if contaminated water overflows into waterways or dams?
To me the questions to be answered are vast and seem not to be addressed.
Do such potentially grave, irreversible and hence permanent risks justify the need for this gas?
We are selling our futures for a short term benefit!
