There are many good reasons why the general public, and in particular farmers, are concerned about coal seam gas (CSG) extraction. There are major gaps in our knowledge about the future impacts of CSG production in Australia.
With respect to groundwater, the time to impact can be long (decades or more). Once a problem is detected it could be too late to do anything. Thus the short term benefits obtained by one generation could have long-lasting impacts on future generations.
CSG production can be done with minimum impact on adjacent groundwater systems, but like any of these complex operations there is always a risk an accident will happen. And when it does happen what will that impact be? This needs to be studied up-front.
