Protecting the water wealth of the Great Artesian Basin is the latest challenge for the coal seam gas industry, writes Ben Cubby.
The basin has existed in its current form for millions of years, but one of the biggest tests to its existence will come in the next decade. Beneath the layers of water lie some of the world’s most extensive coal seams. Just as the sandstone aquifers contain water, so the coal seams contain methane.
The root of the problem, he says, is that politicians pay little attention to the long-term effects of decisions, especially the impact of mining on water resources.
“One thing people must have is food and water, but we are destroying that for one-off payments from mining,” he says.
“No one has a clue of the geology of aquifers. Once fractured, there’s no possibility for them to be fixed. You can’t mine without fracturing the aquifer.”
“The single most important thing you can have is water,” Mr Ball said.
Senior energy analyst Gundi Royle has broken ranks with her colleagues, attacking industry and regulators for failing to conduct independent regional modelling of the groundwater impacts of up to $80 billion in planned coal seam gas (CSG) development.
She said that State governments were so enamoured with projected revenue “they cannot regulate efficiently. They have failed from the outset. They are trying to run behind the ambulance but they will not be able to catch it”.
With opponents to coal seam gas fighting the industry on many fronts the news that gas producers pay nothing for five years has been met with disbelief.
Those opposed to the industry have been questioning its impact on the environment in particular ground water – but now they want to know how a multinational run industry can receive such a significant financial boost from the state government.
There’s a new mining boom in New South Wales and a new state government too. So what now for coal mining and coal seam gas extraction, the environment and agricultural lands around Sydney,
the Hunter Valley, the Illawarra and beyond?
The Coming Famine – Constraints to global food production in an overpopulated, affluent and resource-scarce world. Worldwide, groundwater is running out at an alarming rate, especially in regions using it to grow food.
The only company in Britain using hydraulic fracturing to release natural gas from shale rock says the controversial technique probably did trigger earth tremors in April and May. Fracturing operations were suspended on May 27 following the detection of a tremor centred just outside Blackpool.
Hydrogeologist, John Polglase, digs into the many layers of the Great Artesian Basin, and gives a fascinating insight into how the GAB is formed.
But if it comes to a choice, food must win out over energy.
If the choice does become necessary, it should not be made by default.
Decisions to exploit energy resources must not be made prematurely so that they pre-empt the decision to protect the best agricultural land in a continent where it is in short supply.
PRIME agricultural land in the black soil plains in northern NSW, regarded as the best in Australia, is being taken from farming communities by coal seam gas mining companies in a form of ”legalised theft”, a retired NSW Supreme Court judge told a public meeting in Gunnedah yesterday.
