Management of coal seam gas (CSG) by-product water : a case study on Spring Gully Mine Site in Queensland, Australia

The study addresses two current issues – namely the rapid increase in Coal Seam Gas (CSG) developments and the associated by-product water productions, and also the scarcity of water as a resource in the study area of Queensland. This paper looks at site-specific ways of managing CSG by-product water (CSG water). The CSG production site investigated is located in Spring Gully. The Site’s current water management practices involve treatment of CSG water with Reverse Osmosis (RO) and release of the treated water into a creek nearby. This study discusses possible beneficial re-uses of CSG water. In particular it looks at the costs and benefits associated with re-use for potable purposes, mining processes, and irrigation/farming applications.
