The project aims to address key questions about the development and integration of advanced materials and functional molecules into cutting-edge analytical tools for screening emerging environmental pollutants. This is expected to generate fundamental and applied knowledge in analytical chemistry, using an interdisciplinary approach to engineer materials with precisely tailored properties for ultra-sensitive and selective detection of extremely persistent toxicants in water. Anticipated outcomes are optical materials and functional molecules, integrated into lab-on-a-chip platforms with advanced features for real-life environmental applications – with significant benefits for addressing major environmental and health treats to our society.Read moreRead less
Nitrous oxide and methane emissions from South East Queensland waterways and influence of wastewater discharges. Climate change caused by greenhouse gas emissions is one of the most serious challenges facing mankind. Substantial emission reduction must be achieved, with responsibilities to be shared by all sectors.

Climate change caused by greenhouse gas emissions is one of the most serious challenges facing mankind. Substantial emission reduction must be achieved, with responsibilities to be shared by all sectors. Rivers, estuaries and water storages contribute considerably to global nitrous oxide and methane emissions, much of which is anthropogenic contributed by urban and agricultural run-off and wastewater discharges. Through an in-depth study on several rivers, estuaries and reservoirs in South East Queensland, this project will provide data to enable reliable estimation of such emissions in Australia, and deliver knowledge and tool support for the development of strategic catchment management strategies.Read moreRead less

There are over 80,000 contaminated sites in Australia and >750,000,000 hectares of land impacted by soil acidity, sodicity, heavy-metals, nutrients and agricultural chemicals. The research network advances assessment, management and remediation of degraded environments (land, water, and air) through collaboration of the research programs developing sustainable solutions. The collective focus is minimising disposal and impacts of contaminated soil and wastes, and land remediation. By facilitating communication, the network enhances national and international research coordination, interaction with regulators, end-users, industry, and other stakeholders, achievement of critical mass for new initiatives, enhances research training and contributes to a critical National Priority.Read moreRead less
Ecological renovation of constructed wetlands: changing state from algae to macrophyte dominated systems. Mars Confectionary's constructed wastewater treatment wetlands no longer purify its waste waters. Over-burdening has tipped the balance from a plant dominated, clear water system to an algae dominated, turbid system. This project will aid restoration of the Mars wetlands by (1) improving our understanding of alage-macrophyte dynamics in shallow water basins; (2) producing a series of soft en ....Ecological renovation of constructed wetlands: changing state from algae to macrophyte dominated systems. Mars Confectionary's constructed wastewater treatment wetlands no longer purify its waste waters. Over-burdening has tipped the balance from a plant dominated, clear water system to an algae dominated, turbid system. This project will aid restoration of the Mars wetlands by (1) improving our understanding of alage-macrophyte dynamics in shallow water basins; (2) producing a series of soft engineering, ecologically based techniques for the management / rehabilitation of natural and constructed shallow water bodies which receive high nutrient loads; (3) improve decision support tools for the renovation and sustainable management of the Mars Confectionary, and similar food processing industry constructed wetlands.Read moreRead less

Mineral transformation and oxidant production in subsurface environments. Sporadic influx of oxygen-rich rainwater / groundwater into subsurface waste sites induces dramatic biogeochemical changes which greatly influence the transport of contaminants present.

Sporadic influx of oxygen-rich rainwater / groundwater into subsurface waste sites induces dramatic biogeochemical changes which greatly influence the transport of contaminants present. In this project, fundamental knowledge gaps regarding the impacts of redox oscillations upon contaminant behaviour in these sediments will be addressed through a comprehensive program of field studies at a purpose-constructed experimental facility in an existing waste site, and complementary laboratory investigations. The intended outcomes are to improve understanding of contaminant mobility at the field-scale in these pervasive sites spread across the globe, and provide critical insight into their remediation using cost-effective techniques.Read moreRead less
Modelling contaminant dynamics in a well-mixed/stratified estuary. The proposed mixed/stratified estuarine model is unique and will predict effects of stormwater discharge on water quality, provide guidelines for loading from various contaminant sources, assess impact of marine construction activities, establish effects of natural and anthropogenic resuspension and determine spatial/temporal changes in contaminant distributions. Knowledge generated will assist making decisions locally and overse ....Modelling contaminant dynamics in a well-mixed/stratified estuary. The proposed mixed/stratified estuarine model is unique and will predict effects of stormwater discharge on water quality, provide guidelines for loading from various contaminant sources, assess impact of marine construction activities, establish effects of natural and anthropogenic resuspension and determine spatial/temporal changes in contaminant distributions. Knowledge generated will assist making decisions locally and overseas regarding the protection of valuable living resources, the future environmental status of estuarine systems under alternative management and remedial strategies, management contaminated sediments, new legislation for best management practise, and support for long-term policy development for this estuary type.

Our research will provide a new, more sensitive method of detecting the effects of pollution on animals living in coastal waterways, and allows contamination to be managed before it does permanent biological damage. Australia is one of the most urbanized nations in the world, with most of its population living on the coast and many of the nation's coastal waterways are under unsustainable pressure from pollutants. There is an urgent need for new technologies to help protect Australia's biodiversity, while sustaining the continued human use of our iconic coastal environments. Our work will establish proteomics as new environmental monitoring system.Read moreRead less
Electrochemical treatment of problematic water recycle waste streams. Supply of potable water to Australia's major urban areas is a major challenge to growth and quality of life. Indirect potable reuse via membranes can address this issue, as it offers an inexpensive and sustainable water supply, as well as leveraging new water sources.

Supply of potable water to Australia's major urban areas is a major challenge to growth and quality of life. Indirect potable reuse via membranes can address this issue, as it offers an inexpensive and sustainable water supply, as well as leveraging new water sources. However, the potential impact of the generated reject concentrates on aquatic and human health is potentially of large concern. Our project helps address this, by making reject treatment economically and environmentally much more sustainable, and thereby future-proofing the technology. In addition, it develops technology that can be used worldwide to treat other recalcitrant streams (e.g., hospital, tannery, pulp and paper), is highly scalable, and is low in operating cost.Read moreRead less
