Are acidic mine lakes usable as regional water resources? After the de-commissioning of open-cut mines, the voids frequently fill with water. In Australia, hundreds of mine lakes will develop over the next ten years and beyond. When the base mineralogy is pyritic the water can become highly acidic with high concentrations of dissolved metals. These mine lakes frequently exist in regions where water resources are in short supply. This project will investigate possible strategies to remediate such ....Are acidic mine lakes usable as regional water resources? After the de-commissioning of open-cut mines, the voids frequently fill with water. In Australia, hundreds of mine lakes will develop over the next ten years and beyond. When the base mineralogy is pyritic the water can become highly acidic with high concentrations of dissolved metals. These mine lakes frequently exist in regions where water resources are in short supply. This project will investigate possible strategies to remediate such lakes and assess the possibility of using mining lakes as valued water resources in these regions. The primary outcome of the research will be improved management of the lakes for optimal long term water quality.Read moreRead less
Amelioration strategies to reduce environmental deterioration and agricultural production losses in water repellent regions. Millions of hectares of potentially productive agricultural land in Australia are affected by water-repellency. Water repellency causes non-uniform infiltration of water in soils and promotes surface erosion. Consequently, water repellent soils cannot be satisfactorily used for agricultural production, resulting in production losses of millions of dollars annually. This in ....Amelioration strategies to reduce environmental deterioration and agricultural production losses in water repellent regions. Millions of hectares of potentially productive agricultural land in Australia are affected by water-repellency. Water repellency causes non-uniform infiltration of water in soils and promotes surface erosion. Consequently, water repellent soils cannot be satisfactorily used for agricultural production, resulting in production losses of millions of dollars annually. This investigation is part of a genuine international effort that will develop new procedures to ameliorate water-repellent soils. New and improved mathematical models and decision support tools will also be developed to improve water-repellent land management, reduce environmental risk and minimise agriculture production loss.Read moreRead less
Wetland regeneration for effluent reuse, acid sulfate soil management and carbon credits. This project will research and develop a full-scale effluent reuse wetland to manage acid sulfate soils, regenerate wetlands and sequester atmospheric carbon. Many rural communities worldwide are affected by acid sulfate soils, unsustainable effluent disposal and wetland degradation, and the Greenhouse Effect threatens all coastal areas worldwide. This project is located at Byron Bay, a coastal and predomin ....Wetland regeneration for effluent reuse, acid sulfate soil management and carbon credits. This project will research and develop a full-scale effluent reuse wetland to manage acid sulfate soils, regenerate wetlands and sequester atmospheric carbon. Many rural communities worldwide are affected by acid sulfate soils, unsustainable effluent disposal and wetland degradation, and the Greenhouse Effect threatens all coastal areas worldwide. This project is located at Byron Bay, a coastal and predominantly rural electorate in northern NSW that is strongly affected by this combination of environmental stresses, causing serious degradation of water quality culminating in regular fish kills. The technology developed from this project will be readily transferable to other rural coastal communities worldwide.Read moreRead less
