Eight years into a drought Australia's water sources are becoming increasingly depleted, so we need to reduce water consumption and consider using alternative sources of water. Increased use of rainwater is one of a number of solutions available. However, current recommendations state that rainwater can be safely used for purposes other than drinking, but because of potential contamination and limited evidence regarding safety, drinking untreated rainwater is not approved by state health departments. The main outcome of this study will be to determine whether drinking untreated water from rainwater tanks poses a significant health risk. Additionally, we will determine if specific tank or maintenance characteristics can be identified that increase illness risk. The study design consists of following the health of 300 families who drink unboiled rainwater. Families will have a special tap installed that draws water through a water treatment unit (WTU). Half the families will have a working WTU and half will have a sham unit identical in appearance. The functional units sterilise water to remove any microorganisms present, while the sham filters have no effect. All participating families will keep a health diary for one year to record how often they suffer gastroenteritis. Neither the families nor the research workers will know which type of filter has been fitted. Water samples will be collected from selected households. At the end of a year the number of illnesses in the two groups will be compared. If those drinking rainwater from a sham filter suffer more often, then rainwater would be implicated as a source of gastroenteritis. This study will provide health authorities with a better understanding of the relationship between rainwater consumption and human health, and will provide data regarding safe uses of this alternative water source.Read moreRead less
Improving Risk Assessment For Recycled Water: Domestic Laundries And Recreational Parks

Summary
Recent droughts in Australia have meant that recycled water is becoming increasingly important to ensure the sustainability of our water resources. There are four different classes of recycled water (Class A, B, C and D), depending on the level of microbiological contamination. The potential level of exposure of the population to recycled water determines the class of water suitable for various reuse purposes.

There are four different classes of recycled water (Class A, B, C and D), depending on the level of microbiological contamination. The potential level of exposure of the population to recycled water determines the class of water suitable for various reuse purposes. The need to address water recycling issues in Australia has resulted in increasing numbers of innovative recycling schemes such as dual reticulation systems which supply two qualities of water to households, one of high quality for drinking and a second piped system delivering treated recycled water for non-potable (non-drinking) use. In this project, we will investigate the safety of using recycled water in different situations by using water with different known concentrations of micro-organisms to simulate recycled waters of different classes. Most state health authorities in Australia do not approve the use of recycled water for machine washing because of a lack of safety data, but its use in laundries could significantly reduce the need for high quality drinking water. We will perform experiments to help determine the safety of using recycled water for rinsing clothes during a washing machine cycle. Another use of recycled water is for irrigation of recreational parks. Because of safety concerns, when recycled water of Class B or C is used, some states advocate that the public must wait at least 4 hours after watering before they can gain access. This time period may be unnecessary. We will perform experiments to assess the potential exposure to micro-organisms in grass for park users at different time periods following irrigation with water of various classes. The information obtained from this project will help in the decision-making of health and water regulatory agencies.Read moreRead less
Determining the impact of protozoan pathogens and strongyle worms on prime lamb production. This research will benefit wool and prime lamb industries nation-wide as sheep scouring is prevalent in high-rainfall areas across Australia. Data generated from the project will be used to educate farmers and reduce the financial burden of sheep scouring.

Data generated from the project will be used to educate farmers and reduce the financial burden of sheep scouring. This project will also enhance Australia's reputation in the disease management sector and will result in reduced risk to public health due to a better understanding and management of zoonotic parasite and microbacterial contamination of carcasses and water catchments.Read moreRead less

The protection of front line responders in a pandemic is essential to underpin an effective response. This research is the only work internationally which will address a key gap in evidence. This research has major implications for the national stockpile and for management of front line responders in a pandemic. These data are urgently needed, not just in Australia, but globally to inform pandemic planning and disease control policy around emerging infections and bioterrorism.Read moreRead less

Cryptosporidium is the major public health concern of water utilities as the parasite has a global impact on the health and survival of millions of people and animals worldwide. It is resistant to chlorine and there are no effective drugs against it. Control strategies therefore rely on understanding how it is transmitted.

Cryptosporidium is the major public health concern of water utilities as the parasite has a global impact on the health and survival of millions of people and animals worldwide. It is resistant to chlorine and there are no effective drugs against it. Control strategies therefore rely on understanding how it is transmitted. This project will conduct a comprehensive study utilising molecular tools to determine if the Cryptosporidium in humans is the same as that derived from water contamination sources (animals, sewage etc). The outcomes of this project will result in the development of more targeted, cost-effective preventive measures to minimize exposures to infections, accurate risk assessment, and scientific management of the watershed.Read moreRead less

Summary
Addressing current and future water shortages requires substitution of high quality drinking water with alternative water sources for an expanded range of purposes. However, potential adverse health effects must be avoided. This project measures health risks associated with a variety of alternative water sources and water use combinations. Project outputs will help determine appropriate requirements for water treatment and help refine guidelines to ensure that water use is safe.

Summary
Infectious disease outbreaks are driven by complex interactions between humans, animals, vectors, and the environment. Globally, outbreaks have been increasing in frequency and magnitude, e.g. Ebola and SARS. There is an urgent need to improve public health intelligence by accurately identifying the causes, timing, and hotspots. This project will develop advanced modelling strategies for improving our understanding of outbreaks, and optimise public health interventions to protect human health.
