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.

Fate of micropollutants in water recycling: influence of dissolved organic matter. 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 P ....Fate of micropollutants in water recycling: influence of dissolved organic matter. 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
Monitoring organic matter in drinking water systems using fluorescence spectroscopy: improved early warning, process optimisation and water quality. Climate change is contributing to elevated organic matter (OM) concentrations in drinking water supplies. If insufficiently treated, OM can lead to unacceptable concentrations of disinfection by-products, considered to be potential carcinogens, as well as taste and odour problems and bacterial re-growth in the distribution system. Currently availabl ....Monitoring organic matter in drinking water systems using fluorescence spectroscopy: improved early warning, process optimisation and water quality. Climate change is contributing to elevated organic matter (OM) concentrations in drinking water supplies. If insufficiently treated, OM can lead to unacceptable concentrations of disinfection by-products, considered to be potential carcinogens, as well as taste and odour problems and bacterial re-growth in the distribution system. Currently available on-line monitoring techniques give limited information regarding the nature of OM; however, fluorescence spectroscopy has shown promise in this regard. Hence, this project aims to provide an on-line monitoring protocol utilising fluorescence to aid utilities in their provision of safe drinking water, thus addressing the National Research Priority goal water – a critical resource.Read moreRead less
