The Pilliga Forests are under threat from more propsed CSG mines. Plans are to clear 2,400 hectares of bushland, habitat belonging to up to 15 national threatened species and 48 threatened NSW species of flora and fauna. One of the main threats of CSG is the contamination of water aquifers, and the Pilliga is right on top of the Great Artesian Basin, one of the world's largest underground water supplies. Local farmers in would be using polluted water for feeding and irrigation should the project go ahead. Being Australia's largest food bowl means the threats extend far beyond the local community. Waste product, or grey water, sits in the open to evaporate, polluting the atmosphere, or spills (here and here) occur directly polluting the surrounding landscape.
