AUSTRALIA'S coal seam gas industry could extract an average of 300 gigalitres from groundwater systems every year for the next 25 years, experts predict.
That amount of water would be more than half as much as is presently extracted from the Great Artesian Basin each year.
The "conservative" projection is contained in a submission from the National Water Commission that was among hundreds put to a NSW parliamentary inquiry into coal seam gas.
The commission said coal seam gas offered substantial economic benefits but that if it was not managed and regulated properly risked having significant, long-term and adverse impacts on surface and groundwater systems.
