The objective of this project is the discovery of novel methods for the treatment and reuse of water for both industrial and household applications. Improved treatment systems with the potential for water reuse offer significant improvements to our overall water management potential. The first part of the project is designed to focus on the study of hot bubble column evaporators for solute decomposition, sterilisation and the de-watering of heavily contaminated industrial wastewater. The second part would be based on the study of a suitable depth filter medium for the treatment of partially treated household sewage water. This is designed to form part of an on-site household sewage water treatment and reuse system which is currently being developed.Read moreRead less

Data-driven water quality treatment management decision support system. This project aims to develop a robust decision support system to predict manganese and the character and concentration of dissolved organic matter in drinking water reservoirs, using intelligent algorithms and data collected through remote autonomous instrumentation. These predicted water quality parameters could be used as model input variables to provide real-time decisions for plant operators on the required treatment regime for incoming raw water, and advise them on the optimal reservoir offtake depth. This will potentially minimise treatment costs and health risks for consumers. The ultimate goal is to significantly enhance current water supply management practices.Read moreRead less

This project aims to improve the estimation of the age of groundwater. Understanding groundwater age is critical for sustainable management and environmental tracers are increasingly used for this purpose. However, groundwater samples are inevitably mixtures of water of different ages. Since for most tracers the relationship between tracer concentration and age is not linear, different tracers can produce different mean ages for the sample. This project aims to determine whether it is possible to determine moments of the groundwater age distributions from measurements made with different environmental tracers. The project also aims to examine whether the degree of heterogeneity within the aquifer can be determined from the disparity between ages obtained with different tracers. This project aims to tackle the largest problem with using groundwater chemistry to estimate water age – that mixing processes in the subsurface are never known. Solving this problem will allow much more accurate estimates of groundwater velocity and aquifer recharge rates. The groundwater industry contributes an estimated $6.8 billion per annum to the Australian economy, and this project will contribute to the sustainable management of the groundwater resource.Read moreRead less

Summary
The tropical waters of northern Australia contain unique and diverse aquatic species that are adapted to the seasonally variable climate. Many species rely on seasonal river flows to move, forage, reproduce and fulfil critical life history stages, particularly in ephemeral rivers which become disconnected in the dry season. River flows and harvest are known to influence both freshwater and marine fish and fisheries. However, river flows have been modified in several tropical catchments by water ....The tropical waters of northern Australia contain unique and diverse aquatic species that are adapted to the seasonally variable climate. Many species rely on seasonal river flows to move, forage, reproduce and fulfil critical life history stages, particularly in ephemeral rivers which become disconnected in the dry season. River flows and harvest are known to influence both freshwater and marine fish and fisheries. However, river flows have been modified in several tropical catchments by water abstraction and development of water storage infrastructure for agriculture and drinking water. Additionally, there is increasing pressure to develop new water resource infrastructure in northern Australia. A large and disparate body of literature exists that has documented the relationships between tropical fish species and the seasonal variations in river flow. Production of several commercially, recreationally, and traditionally important tropical aquatic species is linked to flow, suggesting that these may be at risk from the multiple pressures of water abstraction and harvesting, warranting the need for a synthesis of current knowledge on water abstraction impacts and identification of knowledge gaps for targeted future research.
We will address this priority task through the delivery of a stakeholder targeted synthesis of current knowledge on the impacts of water abstraction on tropical aquatic species by a team of recognised experts who have worked extensively on the flow dependence of tropical aquatic species in northern Australia. Through this synthesis, we aim to increase stakeholder understanding of water abstraction impacts on aquatic species.
Objectives: 1. Determine key directives for the synthesis during initial meeting in Darwin with the NT government research advisory committee 2. Review and synthesise relevant grey and published literature 3. Identify potential risks of surface water abstraction on priority fish species and identify critical knowledge gaps and future research needs 4. Share the outcomes with project stakeholders and provide research advice Read moreRead less

Industry needs positive dialog with these groups to build up trust and ultimately cooperation on sustainability issues.
Fishers have often been blamed for much that is wrong with the marine environment. However fishers understand that fishing and conservation are natural bedfellows as their livelihood depends on sustaining the ocean ecosystem and the resources within.
The seafood industry therefore needs to highlight the long-term benefit of balancing the need for conservation against the need for food and other services. In the UK there is a broad seafood industry perspective that fishers must be recognised as an essential part of building a sustainable future for the marine environment.
Phil, has been working in this field for the UK seafood industry for the past 20 years. Initially engaging with environmentalists when the rest of the industry thought it was 'crazy' to do so. He successfully managed to bridge the gap between conservationists, industry and government and for the last 10 years has run the UK's sustainable fishing advisory group, which brings together industry, conservationists and government membership.
It is felt that the seafood industry would greatly benefit and gain positive outcomes from the experience Phil has gained over the last 20 years. This is an opportunity to improve the communication, respect and cooperation between industry and conservationists that is so sorely needed. Objectives: 1. Disseminate to key industry and government stakeholders international advancements in water quality treatment technology as it relates to the prawn and barramundi farming industries.

Starting in the mid 1980s, Australia has experienced an increased public awareness of harmful algal blooms, especially their suspected involvement in causing fish kills and feared public health risks following consumption of contaminated seafood products and drinking water supplies. If not adequately monitored and managed, the economic impacts on Australia's developing aquaculture industry and on both domestic and export markets could be devastating. An example of the first problem is the 1989 bloom event by the golden-brown flagellate Heterosigma akashiwo in Big Glory Bay, New Zealand, which killed NZ$ 12 million worth of cage-reared chinook salmon. An example of the second problem is the 1993 New Zealand outbreak of neurotoxic shellfish poisoning by the dinoflagellate Gymnodinium cf. breve (NSP; 180 illnesses, no deaths) which led to export losses of NZ $ 4.5 million in the first quarter of 1993 and a 25% decrease in domestic shellfish demand . Similarly, positive test results are now available from Australian shellfish products for paralytic shellfish poisons (NSW, TAS,VIC,SA), diarrhetic shellfish poisons (TAS), amnesic shellfish poisons (VIC) , neurotoxic shellfish poisons (VIC) and cyanobacterial peptide toxins (WA). While algal biotoxins only in extreme cases lead to human fatalities, it is the so-called "halo"-effect of bad publicity resulting from a few human poisonings that can devastate aquaculture industries. Compared to our neighbour New Zealand, which spends $3.2 M per year in biotoxin monitoring efforts (most comes from the Ministry of Health, with industry providing $750,000 per year via an industry levy), Australian efforts in this area of quality assurance and environmental protection of aquaculture operations are unsatisfactory. Objectives: 1. To host a successful international conference dealing with: (1) Ecology and oceanography of harmful algae events; (2) Taxonomy of the causative organisms; (3) Chemistry of the toxins involved; (4) Management of toxic and harmful events; and (5) Pharmacological and epidemiological aspects. The conference will comprise: Keynote lectures, Oral and poster presentations, Round table discussions; Workshops; as well as a Social Programme including excursions to key Tasmanian aquaculture operations. A conference web site on the internet will also be created. Read moreRead less

This project aims to determine how non-conventional lithium and silicon isotopes can be used to understand groundwater processes using an innovative source-to-target approach. The project aims to apply these isotope tracers to trace the water cycle within a well constrained system: an island aquifer with a dense borefield which has been analysed using traditional isotopic techniques. Supporting hydrochemical data will be used to determine the relationship of the isotopes with environmental processes. The project impact will be the development of new methods to help understand our groundwater resource. The improved process understanding will be translated to groundwater management in general. The projects' focus on carbonate aquifer systems typical of coastal regions of southern, eastern and western Australia will have relevance to groundwater management in urban areas such as Perth and in rural areas for tourism and viticulture, and for management of natural resources in National Parks.Read moreRead less
