3. Frack Free Geraldton says that fracking can “turn our water into a dangerous chemical cocktail”.
The Oil and Gas Industry says using toxic chemicals in shale fracking will not turn our water into a dangerous chemical cocktail.
Frack Free Geraldton and the CCWA didn't say that it will, just that it can.
And the APPEA didn't say that it can't, just that it won't.
A paragraph in the SevenWest report quoted CSIRO saying the risks of water contamination are low, in most cases.
However, the CSIRO website adds that the risks are low WHEN MANAGED PROPERLY.
This is a self evident statement however, as any contamination that has occurred can obviously be chalked up in hindsight to poor management.
What the APPEA and the Oil and Gas Industry in general haven't convinced the world of is that "this time" they'll manage it properly.
In addition to this...
SevenWest state in their report:
"That illustration (the water bottle) would appear to reflect a substantial contamination of the water by the black “toxic chemical” fluid. In the order of 70% of the water appears to be substantially “contaminated” by the black fluid."
But again, they seemed to have missed the entire point of the image. 70% of the water isn't poisoned. ALL OF IT IS.
And it only took 30mL to do it.
Moreover, CCWA say that the APPEA's claims of water never being contaminated by fracking are based entirely on a narrow interpretation of the term "fracking". They say there is extensive documented evidence of fracking well failure and subsequent leakage (of gas and fracking chemicals) into ground water.
SevenWest concluded this point by stating:
CCWA have not produced any evidence that hydraulic fracking fluid has in the course of any hydraulic shale gas fracking process permeated a fresh water aquifer. Its contentions are against the scientific literature. The advertisement is misleading in this regard.
But by SevenWest's own acceptance of the term "fracking" applying to the entire process of gas extraction, the CCWA HAS produced evidence that fresh water has been polluted.
In fact, they linked to a very thorough study that you can read here:

Here's a taste:
"poor well integrity is a far more likely cause of elevated concentrations of thermogenic methane in shallow groundwater and water supplies than pathways induced solely by hydraulic fracturing. Examples of leaks in shale gas wells have been reported and fines imposed."
In other words, the upward propagation of hydraulic fractures may not be the direct cause of the contaminations of fresh water aquifers, but other parts of the overall gas extraction process have demonstrably contaminated drinking water numerous times in the past.
Why SevenWest chose to semantically interpret "fracking" in this case, but accept that it applies broadly to the entire process in point 1, is unclear.
