Assessing maternal exposure to persistent toxic substances and risk of adverse birth outcomes. There are numerous sources of persistent toxic substances (PTS) and due to their long half life in the environment they can increase in concentration over time, increasing the risks of human exposure. Australia is a signatory to the Stockholm Convention and this project both assists in the meeting Australia's obligations but also addresses the important subject of the relationship between environment, ....Assessing maternal exposure to persistent toxic substances and risk of adverse birth outcomes. There are numerous sources of persistent toxic substances (PTS) and due to their long half life in the environment they can increase in concentration over time, increasing the risks of human exposure. Australia is a signatory to the Stockholm Convention and this project both assists in the meeting Australia's obligations but also addresses the important subject of the relationship between environment, health and risk. The study will be the first of its type to systematically measure maternal exposure and link the risk of adverse birth outcomes. It will significantly improve our ability to assess the impact of chemicals on health. It will also provide benchmark information for a use in national standard setting and policy development.

This project will develop innovative new water treatment processes to selectively remove bromide and iodide from potable source waters. The project promotes Australia as a leader in water treatment technology. Successful outcomes will have excellent potential for international commercialisation by spin-off companies and will provide economic benefits and prestige locally. Economic benefits include lower costs to water utilities through the availability of improved technology for treatment of marginal quality water supplies and improved ability to comply with water quality guidelines. Public perception and confidence in water supply quality will be enhanced, due to reduction in taste and odour issues and disinfection by-products. Read moreRead less
Advanced water treatment technologies to minimize the formation of emerging disinfection by-products in potable and reuse water. Disinfectant management and disinfection by-products are of concern to water utilities, water treatment researchers and consumers worldwide. The project will make a world-class contribution to these issues, through use of state-of-the-art equipment and developed technologies. Sophisticated characterization of disinfection by-product precursors, especially poorly define ....Advanced water treatment technologies to minimize the formation of emerging disinfection by-products in potable and reuse water. Disinfectant management and disinfection by-products are of concern to water utilities, water treatment researchers and consumers worldwide. The project will make a world-class contribution to these issues, through use of state-of-the-art equipment and developed technologies. Sophisticated characterization of disinfection by-product precursors, especially poorly defined less volatile species, will provide insights into the relationship between their chemical structures and behaviour in treatment processes, benefiting all water utilities. The project will inform new drinking water guidelines and assist water utilities to balance the competing requirements of maintaining effective pathogen barriers versus disinfection by-product control.Read moreRead less
Novel Technology for Improving Disinfection Outcomes in Regional and Remote Drinking Water Distribution Systems. Climate shifts have led to water supply shortages in many areas of Australia, both in rural and remote regions and in cities. To ease water shortages, transportation of water over long distances is becoming increasingly necessary. A major impediment to transfer of water through long mains is management of the disinfectant: most disinfectants decay too rapidly, leaving consumers at ris ....Novel Technology for Improving Disinfection Outcomes in Regional and Remote Drinking Water Distribution Systems. Climate shifts have led to water supply shortages in many areas of Australia, both in rural and remote regions and in cities. To ease water shortages, transportation of water over long distances is becoming increasingly necessary. A major impediment to transfer of water through long mains is management of the disinfectant: most disinfectants decay too rapidly, leaving consumers at risk of pathogen exposure. Chloramination, the most viable disinfection technology for this purpose, suffers from a process called nitrification which accelerates disinfectant decay. In this project, we are developing an innovative, patented process to prevent nitrification, which will allow safe and effective disinfection of water supplies in long pipelines.Read moreRead less
Interaction of Cryptosporidium lifecycle stages with aquatic biofilm communities. Cryptosporidium is the most common non-viral cause of diarrhoeal disease in humans worldwide, and of increasing significance as a cause of disease in livestock and wildlife. It is one of the most significant waterborne pathogens and a major challenge to the provision of safe drinking water by water utilities. Biofilms are a poorly studied component of Cryptosporidium's ecosystem, and can act as an environmental res ....Interaction of Cryptosporidium lifecycle stages with aquatic biofilm communities. Cryptosporidium is the most common non-viral cause of diarrhoeal disease in humans worldwide, and of increasing significance as a cause of disease in livestock and wildlife. It is one of the most significant waterborne pathogens and a major challenge to the provision of safe drinking water by water utilities. Biofilms are a poorly studied component of Cryptosporidium's ecosystem, and can act as an environmental reservoir of the parasite in water storages and pipes and an unpredictable source of water contamination. This project will investigate the nature of this reservoir and factors that support the parasite's survival with a view to providing information of value in limiting the public health significance of the biofilm reservoir.Read moreRead less
Optimisation of cell culture and molecular typing for the characterisation of Cryptosporidium in water. Cryptosporidium is an important waterborne agent of diarrhoeal disease in people and animals.

Cryptosporidium is an important waterborne agent of diarrhoeal disease in people and animals. Improved methods for accurately detecting viable parasite stages recovered from water are a priority research need for the water industry. They are dependent upon improved in vitro cultivation procedures that can be combined with DNA-based assays for identifying species and strains of Cryptosporidium and closely related protozoa recovered from freshwater. This project addresses these needs in a collaborative study between scientists at Murdoch University with expertise in both in vitro cultivation and genetic characterisation of Cryptosporidium, and scientists from two of the major water utilities in Australia.Read moreRead less
Treating wastewater for potable reuse: removal of chemicals of concern using advanced oxidation processes. The project promotes Australia as a leader in water reuse technology and is of benefit to reuse schemes globally.

The project promotes Australia as a leader in water reuse technology and is of benefit to reuse schemes globally. Several major reuse schemes are planned for Australia and it is well recognised that robust science is needed for public confidence. Community perception is a serious barrier to potable reuse and the results from this project will provide essential and independent information for informed decision making. The oxidation processes proposed will improve the quality of both recycled water and waste brine, providing environmental and economic benefit. This is particularly significant for regional Australia, where there is substantial demand for both water reuse and cost-effective waste disposal in the absence of ocean discharge.Read moreRead less
