A Fundamental Understanding of Methane Driven Denitrification. Eutrophication in waterways due to the presence of nutrients including nitrogen is a well-recognised environmental problem. Moreton Bay, for example, used to receive 3,300 tons of nitrogen each year from point sources. Stringent nitrogen discharge limits have therefore been imposed on most wastewater treatment systems across Australia.

Eutrophication in waterways due to the presence of nutrients including nitrogen is a well-recognised environmental problem. Moreton Bay, for example, used to receive 3,300 tons of nitrogen each year from point sources. Stringent nitrogen discharge limits have therefore been imposed on most wastewater treatment systems across Australia. Nitrogen removal from wastewater is commonly accomplished in a biological way involving the use of bacteria. The project aims to investigate a particular bacterial community, which is able to perform nitrogen removal from wastewater with methane as a renewable carbon source. The project will therefore lead to more sustainable wastewater treatment systems.Read moreRead less
MoistureMap: A soil moisture monitoring, prediction and reporting system for sustainable land and water management. Knowledge of the spatial and temporal variation of surface and root zone soil moisture content is critical to environmental sustainability and risk adverse farm management.

Knowledge of the spatial and temporal variation of surface and root zone soil moisture content is critical to environmental sustainability and risk adverse farm management. A paddock scale soil moisture prediction tool will allow i) grain growers to make informed decisions of what to plant and when, based on likely germination rates and crop yield, ii) graziers to be proactive regarding management of stocking rates based on likely pasture growth, and iii) better weather and climate prediction skill. At regional scales moisture information can be used to support claims of drought exceptional circumstances.Read moreRead less
Understanding Fugitive Greenhouse Gas Emissions from Wastewater Systems for Reliable Accounting and Effective Mitigation. Climate change caused by greenhouse gas (GHG) emissions is one of the most serious challenges facing mankind. Substantial reductions in emissions must be achieved, with responsibility shared by all industrial sectors. Wastewater systems contribute to GHG emission through not only energy consumption but also direct emissions of fugitive GHG such as methane and nitrous oxide. T ....Understanding Fugitive Greenhouse Gas Emissions from Wastewater Systems for Reliable Accounting and Effective Mitigation. Climate change caused by greenhouse gas (GHG) emissions is one of the most serious challenges facing mankind. Substantial reductions in emissions must be achieved, with responsibility shared by all industrial sectors. Wastewater systems contribute to GHG emission through not only energy consumption but also direct emissions of fugitive GHG such as methane and nitrous oxide. This project aims to deliver the urgently needed knowledge and technology support to the Australian wastewater industry to achieve reductions in fugitive emissions. The research will also provide support to the greenhouse office via more reliable estimation of such emissions.Read moreRead less
Application and evaluation of passive samplers for monitoring aquatic pollution. Pollutants in water bodies pose a threat to environmental and human health. Monitoring of chemicals in water has thus become a key challenge for environmental authorities. Sampling based on the
analysis of grab samples is expensive, complicated and provides only patchy data. Passive sampling devices that allow time integrated sampling of pollutants are a promising alternative.

Monitoring of chemicals in water has thus become a key challenge for environmental authorities. Sampling based on the
analysis of grab samples is expensive, complicated and provides only patchy data. Passive sampling devices that allow time integrated sampling of pollutants are a promising alternative. This collaborative research aims to evaluate a series of existing and novel passive samplers both in laboratory and field conditions and determine sensitive parameters that significantly influence sampler behaviour.
The project should provide a set of new tools for more effective management of water pollution.Read moreRead less
An innovative strategy for stormwater remediation and reduction of contaminant supply from catchments. Many urbanised harbours world-wide are polluted and the main source is stormwater. Currently, emphasis is to remove gross pollutants from stormwater using numerous devices scattered through the catchment. In a radical shift from traditional approaches, we will identify primary contaminant sources in the catchment for later targeted education and regulation and a single remediation device will r ....An innovative strategy for stormwater remediation and reduction of contaminant supply from catchments. Many urbanised harbours world-wide are polluted and the main source is stormwater. Currently, emphasis is to remove gross pollutants from stormwater using numerous devices scattered through the catchment. In a radical shift from traditional approaches, we will identify primary contaminant sources in the catchment for later targeted education and regulation and a single remediation device will remove most toxic substances in stormwater currently discharged to estuaries. Stormwater reuse will provide a new valuable urban resource. This paradigm shift in traditional stormwater strategy will ensure biodiversity and ecologically sustainable development of urbanised ports. Port Jackson is used as a test case.Read moreRead less

The application of inverse methods for resolving velocity, density and mixing fields in lakes and estuaries. The two techniques to be developed and tested here will allow the measurement of the 3D density and velocity fields in lakes and estuaries using only simple instruments and with minimum lake obstruction.

The two techniques to be developed and tested here will allow the measurement of the 3D density and velocity fields in lakes and estuaries using only simple instruments and with minimum lake obstruction. Coupled with a Real Time Management System, these techniques can be used to validate numerical models and to simulate scenarios, such as future flood events, which have the potential for contamination of water quality. The output from these simulations is then used, again in real time, to evaluate the new Index of Sustainable Functionality of the water body. When augmented with the results from this research we would have a tool that would help manage lakes and reservoirs to optimize the water quality, while maintaining the supply.Read moreRead less

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
