Summary
Development of electrochemically activated sorbents for PFAS defluorination. This project aims to develop a new treatment technology to completely defluorinate per- and poly-fluroalkyl substances (PFAS) and to treat significant water quantities. The majority of existing water treatment technologies are unable to remove PFAS to the desired extent, are prohibitively expensive or are only useful for a very limited lifespan. This project is expected to develop a new treatment technology with the abi ....Development of electrochemically activated sorbents for PFAS defluorination. This project aims to develop a new treatment technology to completely defluorinate per- and poly-fluroalkyl substances (PFAS) and to treat significant water quantities. The majority of existing water treatment technologies are unable to remove PFAS to the desired extent, are prohibitively expensive or are only useful for a very limited lifespan. This project is expected to develop a new treatment technology with the ability to completely defluorinate PFAS, treat significant water quantities and help address many of the pressing concerns facing water treatment operators. This technology is also scalable, and can potentially be used to treat significant quantities of contaminated water.Read moreRead less

This project aims to assess the utility of near-real-time data from the currently operating space gravity satellite mission to quantify and track flood waters in Australia. Through analysis of the satellite data and fusion of observed signals with rainfall, river flows and conventional hydrological modelling, it expects to create new knowledge of soil moisture and movement of flood waters. Expected outcomes include a capability to improve hydrological models by including the information of water signals obtained from the near-real-time observations. This should provide significant benefits such as more accurate land saturation maps and better predictions of runoff and flood risk.Read moreRead less

Natural flood management: Nature-based flood mitigation in the 21st Century. The 2021-22 floods in Eastern Australia revealed the vulnerability of rivers to climate extremes. To prepare for a future with more intense floods, we must integrate nature-based flood mitigation strategies into river management. This project aims to address the potential of using Natural Flood Management (NFM) as a 21st Century flood mitigation solution. NFM uses natural processes to slow floods, reduce erosion, and mi ....Natural flood management: Nature-based flood mitigation in the 21st Century. The 2021-22 floods in Eastern Australia revealed the vulnerability of rivers to climate extremes. To prepare for a future with more intense floods, we must integrate nature-based flood mitigation strategies into river management. This project aims to address the potential of using Natural Flood Management (NFM) as a 21st Century flood mitigation solution. NFM uses natural processes to slow floods, reduce erosion, and minimise flood risk. Collaborating with NSW government partners the project expects to deliver scientific evidence for NFM and solutions for implementation in river rehabilitation, planning and community capacity building. The results will impact society's ability to adapt, reduce economic costs, and benefit the environment.Read moreRead less
Hydrogeological drivers and fate of spring flow in a semi-arid setting. In arid and semi-arid climates, aquatic and terrestrial ecosystems often rely on groundwater springs. Spring hydrology depends on complex relationships between underlying aquifers and surface conditions, leading to high uncertainties in understanding aquifer-spring-wetland hydrology, which is critical for spring ecosystem protection and to inform management of relevant groundwater-affecting activities. This project will appl ....Hydrogeological drivers and fate of spring flow in a semi-arid setting. In arid and semi-arid climates, aquatic and terrestrial ecosystems often rely on groundwater springs. Spring hydrology depends on complex relationships between underlying aquifers and surface conditions, leading to high uncertainties in understanding aquifer-spring-wetland hydrology, which is critical for spring ecosystem protection and to inform management of relevant groundwater-affecting activities. This project will apply novel hydrogeophysical and hydrochemical methods, and computer modelling, to investigate the source aquifer of, and fate of discharge from the Doongmabulla Springs Complex (DSC), located in an area of future development. Project results will inform spring vulnerability to development pressures and climate effects.Read moreRead less
Electron transport catalysis in organohalide pollutant respiration. This project aims to understand the link between substrate specificity and gene sequence of dehalogenating enzymes in organohalide respiring bacteria (ORB) and the mechanism by which electrons are transferred to dehalogenating enzymes through protein-protein interactions. Organohalides were present in Earth's early history and now pollute the environment globally.

This project aims to understand the link between substrate specificity and gene sequence of dehalogenating enzymes in organohalide respiring bacteria (ORB) and the mechanism by which electrons are transferred to dehalogenating enzymes through protein-protein interactions. Organohalides were present in Earth's early history and now pollute the environment globally. Organohalide respiring bacteria (ORB) can degrade these pollutants by using them as terminal electron acceptors in their respiratory metabolism. This represents one of the most ancient respiratory systems on Earth about which little is known. This project will add to our fundamental knowledge of microbial evolution and metabolic systems, and pave the way for next generation organohalide remediation technologies.Read moreRead less
Improving water quality modelling by better understanding solute transport. Poor stream water quality is a critical problem in Australia and globally. Stream water quality depends directly on pathways and time taken for water to transport pollutants through catchments.

Poor stream water quality is a critical problem in Australia and globally. Stream water quality depends directly on pathways and time taken for water to transport pollutants through catchments. Predicting these pathways is highly challenging and currently requires specialised data. This project aims to better model the movement of water from rainfall to streams, enable greatly improved use of water quality data routinely collected in Australia's catchments and thereby better predict water quality behaviour. Proposed field studies aim to support this development. The outcomes sought are improved planning and management of water quality in our rivers, lakes and estuaries, improved health of these water bodies and improved water supplies.Read moreRead less
