Water under fire: @JeanRoxon reports #Pilliga contamination concerns

A group of farmers and councillors met last week in north-west NSW to take a stand against a Coal Seam Gas (CSG) development proposed in the area. Narrabri Shire councillor Bevan O’Reagan said: “We haven’t got a plan B if the water is damaged.”

Australian gas and oil producer Santos last week submitted its Preliminary Environmental Assessment for a CSG mine in the Narrabri region. This submission follows the successful application by coal company Whitehaven, to increase open-cut mining in the nearby Leard State Forest.

The northern plains region is known for its abundance of coal and gas and lies on the eastern edge of the Great Artesian Basin. The contamination of this aquifer by salt and heavy metals, such as mercury, would have a devastating impact on local agriculture and native flora and fauna.

“From our grazing point of view it [bore water] is 100 per cent of our water,” local farmer Rob Vickery said, “if the water’s damaged then the land’s damaged.”

One of the greatest concerns expressed at last week’s meeting was that excess water produced by CSG mining contained high amounts of saline and some poisons and heavy metals and these would contaminate the bore water. Both Santos and Whitehaven have released impact assessments outlining their intended management of water.

In a public booklet Santos said: “The water we extract during our operations is saline.The water does not contain significant levels of other chemicals.”

Famers were also concerned that through their mining Santos would lower the groundwater level by up to 20 metres.

However, Santos stated that through their “Managed Aquifer Recharge” they will be able to inject treated water from mining back into the aquifer system, thus “mitigate[ing] potential impacts arising from GSG well groundwater abstraction.”

Dayne Pratzky, an environmental activist and farmer from Chinchilla in Queensland was doubtful. He said: “[they] can’t take the water away and have no consequences”. Mr Pratzky also said that similar issues arose with CSG mining near his property in Queensland and that “they are talking salt piles 11 kilometres long, 40 metres wide and 30 metres high.”

Whitehaven’s proposed open-cut mine at Maules Creek a similar concern about water treatment has been raised. The new mine, to be developed in the centre of the Leard State Forest, has received comment over the conservation and treatment of threatened and endangered flora and fauna.

Whitehaven’s ecological impact assessment stated that: “No groundwater dependent ecosystems have been identified within the project boundary,” however, environmental activist from the Leard Blockade, Murray Dreschler, is still worried.

He claims that Whitehaven have stated “that they will drop the water table by ten to fifteen metres for a thousand years.”

“The biggest concern is water,” Mr Dreschler said, “without water everything dies.”

Both Santos and Whitehaven were contacted for comment and both companies declined.

  1. Although I’m a member of the ALP,I’m thinking more and more of the Greens.There is no planet B.

  2. Eddie is right there is no planet B. Planet A (Earth) is the only one we’ve got. As an ex member I feel the ALP will become totally irrelevant if they don’t wake up – and pretty damn quick. The
    right has swung even more so, and the left is switching to the Greens while Labor does not know if it is either.
    Meantime I hope the bush takes note of the electoral success of genuine (I stress genuine) Independents such as Cathy McGowan and give both major parties the finger.
