As outlined by the Intergovernmental Panel on Climate Change the recent observable changes in Earth’s climate can be related and linked to human activates in the past few centuries. Our heavy use on fossil fuels contributed up to 56.6% of the greenhouse gases emitted in 2004 as seen in the figure below (1).This heavy dependence on fossil fuels has encouraged the use, research and development of new alternative energy sources such as Coal seam gas (CSG) which have reduced greenhouse gas emissions. CSG is obtained through drilling into the pores of coal seams then using water to fracture and open the pores in the coal seams which contain high levels of methane. After this fracturing process the pressure within the borehole is reduced and…show more content…

As outlined by the Intergovernmental Panel on Climate Change the recent observable changes in Earth’s climate can be related and linked to human activates in the past few centuries. Our heavy use on fossil fuels contributed up to 56.6% of the greenhouse gases emitted in 2004 as seen in the figure below (1).This heavy dependence on fossil fuels has encouraged the use, research and development of new alternative energy sources such as Coal seam gas (CSG) which have reduced greenhouse gas emissions. CSG is obtained through drilling into the pores of coal seams then using water to fracture and open the pores in the coal seams which contain high levels of methane. After this fracturing process the pressure within the borehole is reduced and the methane along with the water rises to the surface where it can be collected and distributed as needed. (2) The focus of this report is with the associated water that is retrieved from coal seams, the effects it can have on the environment and treatment methods currently being used to combat the impact on the environment.
The biggest area of concern with CSG is the water by-product that is produced when fracturing coal seams. In Australia on average 300 gigalitres of water is extracted from water aquifers and basins through CSG each year. As outlined by the Department of Environment and Resource Management (DERM) the long term impacts on the environment is unknown and there is little research surrounding the area.(3)
