Phytocapping for sustainable waste containment systems and reduction of greenhouse gas emissions and odour from waste disposal sites. Landfills remain the main method of waste disposal in Australia and are a major source of groundwater contamination and greenhouse and odour emissions. This national research program will establish, under a wide range of Australian conditions, whether landfill phytocaps can meet regulatory performance criteria for water infiltration into and gas emissions from clo ....Phytocapping for sustainable waste containment systems and reduction of greenhouse gas emissions and odour from waste disposal sites. Landfills remain the main method of waste disposal in Australia and are a major source of groundwater contamination and greenhouse and odour emissions. This national research program will establish, under a wide range of Australian conditions, whether landfill phytocaps can meet regulatory performance criteria for water infiltration into and gas emissions from closed landfills more effectively, efficiently and sustainably than conventional capping systems. The project will produce (a) a scientific basis for site owners and regulators to agree on the performance and cost of conventional and phyto cover technologies, (b) a manual for the design and permitting of alternative covers and (c)improved scientific prediction of cover performance.Read moreRead less

Development of a Bioassay to Measure Xenoestrogens in Environmental Water Samples. Xenoestrogens in water can cause feminization of fish, amphibians and other wildlife, interfere with reproduction and increase cancer. This research aims to develop a new test to measure xenoestrogens in water, based on a measure of the estrogen-activated genes that are switched on when cells are exposed to estrogens. If the research is successful, it will produce the best test in the world for measuring the effe ....Development of a Bioassay to Measure Xenoestrogens in Environmental Water Samples. Xenoestrogens in water can cause feminization of fish, amphibians and other wildlife, interfere with reproduction and increase cancer. This research aims to develop a new test to measure xenoestrogens in water, based on a measure of the estrogen-activated genes that are switched on when cells are exposed to estrogens. If the research is successful, it will produce the best test in the world for measuring the effects of xenoestrogens on mammalian cells. The test can be used to develop better xenoestrogen removal processes, and to set limits for the levels of xenoestrogens permitted in rivers and creeks.Read moreRead less
A new strategy for design flood estimation in a nonstationary climate. Evidence suggests that global warming will result in an increase in the frequency and/or magnitude of heavy rainfall, leading to flooding with potentially devastating consequences. This study provides a renewed focus on design flood estimation that takes into account a changing climate where assumptions of stationarity are no longer tenable.
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. 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 ....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. 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

Groundwater and the Environment: Understanding the role of groundwater in the maintenance of sustainable ecosystems in Australia.
. 97% of freshwater on earth is groundwater. Despite this, it is undervalued, largely unexplored and poorly understood. In Australia, groundwater plays a critical role in our salinity problem and sustains our ecosystems. It will be a critical water supply in the future, especially in times of drought when surface water is scarce. Our nation's groundwater resources ....Groundwater and the Environment: Understanding the role of groundwater in the maintenance of sustainable ecosystems in Australia.
. 97% of freshwater on earth is groundwater. Despite this, it is undervalued, largely unexplored and poorly understood. In Australia, groundwater plays a critical role in our salinity problem and sustains our ecosystems. It will be a critical water supply in the future, especially in times of drought when surface water is scarce. Our nation's groundwater resources require the same unresounding commitment to preservation that we now see in the Murray-Darling basin. This network develops foundations for a desperately needed National Groundwater Centre to provide research to ensure win-win outcomes for this country's water resources and the users that rely on them.
