CSG could not be scientifically ruled out by the study but is just one of the myriad factors raised that could be contributing.
The bubbling occurs along a 5km stretch of the river, near Chinchilla, where coal seam gas is plentiful, but the source has always been a mystery and an issue of local debate ranging from rotting vegetation to CSG fracking.
