'Toxins in CSG water'
AN ENVIRONMENTAL scientist and campaigner against coal seam gas has produced water test results from the Pilliga in northwest NSW to dispute a claim by Metgasco chief Peter Henderson that community concerns about coal seam gas waste water were "emotional nonsense".
Lock the Gate spokeswoman Boudicca Cerese maintained scientific evidence from Queensland showed coal seam gas waste water contained toxic substances.
Metgasco has repeatedly claimed waste water from its operations was not toxic.
But Ms Cerese said the community had been insulted by Mr Henderson's comments and had every reason to be concerned about the potential impacts of waste water on waterways.
"There is mounting evidence that shows that the waste water produced during coal seam gas operations often contains a complex mix of toxic chemicals, many of which are persistent and bio-accumulative," she said.
She provided The Northern Star with the certified analysis of the Pilliga samples which showed elevated levels of salts, a variety of heavy metals including arsenic, lead and chromium, as well as petrochemicals.
She said coal seam gas waste-water remained toxic even after reverse osmosis.
Mr Henderson said Metgasco had undertaken soil and water testing which had shown the company's production water was not toxic.
"If people have concerns with water samples and quality, or independent data,they should contact the NSW Government," he said.
