Research based on animal uptake from mine tailings is required to quantify comparative bioavailability of mixtures of metals to provide data for mine rehabilitation design during the planning stage. Such data also provides risk assessment in humans. The optimum balance is minimum environmental effects from the rehabilitated mine structure versus minimised cost through planning prior to project commencement. The significant cost of mining ore bodies, particularly by modern open cut methods, is the removal of rock and soil. The research on animal toxicity testings will provide a tool to more accurately detail mine rehabilitation and give quantitative indicators for closure.Read moreRead less

Access to safe drinking water is essential for the economic and social development of Australia. There is increasing interest in applying advanced water treatment processes, such as membrane filtration or ozonation, to treat secondary effluent to a potable standard. This project promotes improved organic pollutant removal and monitoring during advanced water treatment and will contribute to the National Research Priority goal, water - a critical resource, by providing the increased protection of receiving waters including rivers and seawater. Further, as very few studies consider the role of dissolved organic matter for organic pollutant fate in water reuse internationally, this project will help to advance Australia's position in science.Read moreRead less

Summary
Remediation of PFAS contaminated soil using soil washing and immobilisation. This project aims to assess the applicability of soil washing and immobilisation as cost-effective techniques for the remediation of per- and poly-fluroalkyl substance (PFAS) contaminated Australian soils. The project expects to establish the efficacy of the remediation of a range of PFASs, including many polyfluorinated precursors of perfluorinated, chemically-persistent legacy pollutants which are of concern. The proj ....Remediation of PFAS contaminated soil using soil washing and immobilisation. This project aims to assess the applicability of soil washing and immobilisation as cost-effective techniques for the remediation of per- and poly-fluroalkyl substance (PFAS) contaminated Australian soils. The project expects to establish the efficacy of the remediation of a range of PFASs, including many polyfluorinated precursors of perfluorinated, chemically-persistent legacy pollutants which are of concern. The project will provide a scientific basis for understanding the benefits and limitations associated with soil washing and immobilisation techniques and a more comprehensive understanding of future liabilities associated with formation of PFASs from precursors remaining in remediated soils. Collaboration with stakeholders will ensure benefits are captured both commercially and environmentally, as well as removing a potential and on-going health threat to communities exposed to these contaminants.Read moreRead less
Phytoextraction approaches for mitigating heavy metal release from unlined and loosely capped rural landfills. Australian rural landfills are used for storing hazardous wastes which contain toxic metals. Impermeable clay caps are often utilized to encapsulate these wastes and prevent release of pollutants into the environment. The integrity of these caps is crucial and requires constant care. The project aims to develop novel approaches which will improve substantially the long-term environmenta ....Phytoextraction approaches for mitigating heavy metal release from unlined and loosely capped rural landfills. Australian rural landfills are used for storing hazardous wastes which contain toxic metals. Impermeable clay caps are often utilized to encapsulate these wastes and prevent release of pollutants into the environment. The integrity of these caps is crucial and requires constant care. The project aims to develop novel approaches which will improve substantially the long-term environmental safety of rural landfills and deliver additional economic benefits. These approaches involve the use of high-value tree crops and plants capable of extracting toxic metals. Utilization of these plants will create a valuable resource on an otherwise derelict area and this will be of considerable local/regional benefit and national significance.Read moreRead less

This project will examine the forms, transformations and fate of dissolved organic matter (DOM) in aquatic ecosystems and the link to human health with water treatment. Catchment revegetation is a management tool used to reduce excessive nutrient loads to waterways, which in turn causes poor water quality. However, catchment revegetation also produces DOM. DOM is typically poorly characterised and its effect on ecosystem health unclear. DOM also reacts with chlorine in water treatment plants to form disinfection by-products that affect human health. This research is expected to provide important new information to guide future catchment restoration efforts.Read moreRead less

Conservation of threatened species is expensive and success rare or fleeting. Analysis of nearly three decades of threatened species conservation management, and an understanding of the complex of factors that affect success, will help increase the efficiency of conservation planning. Improved understanding of the biological, economic, social and institutional environment within which conservation management occurs will help managers allocate resources appropriately. This type of analysis has never been done for an entire fauna at a continental scale and will have global significance. Furthermore the networks to which the investigators are connected will ensure that the results can be rapidly translated into practice.Read moreRead less
