Short summary
This research characterised the biogeochemical constraints on the origin of methane in an alluvial aquifer, concluding that the most likely source was the upward migration from a directly underlying coal seam. This research was undertaken due to concerns about the effect of coal seam gas production on groundwater quality in the study area. The implications include the fact that no methane is being produced in the aquifer (in situ) and that there is local natural connectivity in the study area.
