This project examined the impact of the expansion of Coal Seam Gas (CSG) production in the Surat Basin on

groundwater levels in the upper Condamine alluvium and the eastern portion of the Great Artesian Basin. The

research highlights potential concerns that would impinge upon the future availability of groundwater to the

irrigation sector. This project benchmarked in priority areas in the Condamine Alluvium groundwater quality,

major ion chemistry, and groundwater and air methane concentrations.
