Lock the Gate investigators have discovered coal seam gas bubbling to the surface along a 5 kilometre stretch of the Condamine River near Chinchilla.
The gas is bubbling to the surface in at least four spots along this stretch of the river and, according to a local landowner, the coal seam gas company operating in the area (Origin) has identified it as coal seam gas and is testing to see which of its seams it comes from.
Lock the Gate Alliance president, Drew Hutton, will be calling a media conference today at 10:30am in front of the Parliamentary Annexe to describe these findings and call for certain actions to be taken.
Mr Hutton, a former resident of Chinchilla, said that, while it was possible for methane to naturally bubble to the surface of waterways, none of the local farmers had ever heard of it happening in the Condamine River.
Also, the fact that it is occurring along several kilometres of the river would suggest it is not an isolated occurrence but a major leak and has found its way to the surface along migration pathways opened up by the de-watering of aquifers or fracking.
"I don't think there is any doubt this extensive leak is linked to the coal seam gas drilling, and probably fracking, that is occurring in nearby wells," Mr Hutton said.
"This is just one cut in the death-by-a-thousand cuts to the environment that will occur when we have the tens of thousands of wells across rural Queensland."
Mr Hutton said the incident had been reported to the Mines and Environment departments by a local landowner but these departments reportedly did not want to know about it.
