This research team consisted of Dr Damien Maher, Dr Douglas Tait, Marnie Atkins, Hanabeth Luke and Paul Macklin. We investigated baseline ("before") groundwater chemistry in areas earmarked for coal seam gas (CSG) development. A major component of this project was to determinine the baseline chemical composition of both soils and groundwater taking high precision measurements of methane concentrations and isotopes. These may act as early indicators of aquifer connectivity in CSG production sites. This project is on-going.
