The use of recycled water has been promoted by policy in many parts of the world under the banner of sustainable water management. Impetus for these policies has been provided by increasing water scarcity driven by population growth and rising per capita water consumption. A major barrier to the success of recycled water use policies can be a lack of community support. A further problem is significant gaps, uncertainties and assumptions in the literature about community attitudes to recycled water use. The aim of this thesis was to bridge these gaps answering the specific research question: What are the components of community attitudes to and satisfaction with recycled water use? This was investigated through an urban Australian case study. / The gaps in literature required a theory building rather than theory testing approach to the research which was facilitated through the case study. Due to the sparse literature and few existing case studies, a broad range of parallel literatures from many disciplines were drawn upon to inform the research. The research structure of the thesis drew 56 observations from the combined literature and case studies. The observations informed the development of 5 broad Research Propositions, which translated into 60 specific Research Hypotheses that were tested with multiple methods including: conjoint analysis, contingent valuation, structural equation modelling and unobtrusive methods. The principal research tool was a panel / repeat cross sectional community survey. Three surveys of the community were undertaken, two prior to the use of recycled water commencing (both with 136 respondents), and the third post recycled water use commencing (with 162 respondents). / The case study site for the research was Mawson Lakes in South Australia, where recycled water is used for non-potable purposes, including garden watering, toilet flushing and car washing, through a dual water supply system. Construction of this Greenfields suburb began in 1997 and is expected to be completed in 2010 by which time there will be 10,000 residents. Recycled water began reticulation through the dual water supply system in April 2005; until that time potable water was delivered through the recycled water pipes. / In answer to the research question, the study found the components of community satisfaction with recycled water use were an individual's positive perception of: - the Water Authority's communication, - trust in the Water Authority, - fairness in the recycled water system's implementation, - quality of the recycled water, - financial value of the recycled water system, and - risk associated with recycled water use (negative relationship) / Other issues investigated in the thesis include: attitudes to recycled water attributes including salt, colour, odour and price (when used for clothes washing, garden watering and toilet flushing), risk perception, attitudes to price, willingness to pay for recycled water quality improvements, willingness to pay for non-market benefits of recycled water use, perceptions of institutions, and other related attitudes. / Results of this investigation contribute to building knowledge and understanding of community attitudes to recycled water use, and hence facilitate sustainable management of water resources. / Thesis (PhDBusinessandManagement)--University of South Australia, 2006.

In this thesis, detection of active water-borne bacteria was achieved by combining flow cytometry with vital dyes that characterise the metabolic status of cells. Following optimisation, these techniques were applied to investigate the activity of bacteria exposed to disinfection, both in the laboratory and in real systems. Raw and potable waters from various locations around South Australia were then analysed to investigate relationships between numbers of active bacteria and those detected by traditional culture-based techniques. / Thesis (PhDAppliedScience)--University of South Australia, 2005.

This thesis presents work that focused on the customised detection and measurement of aluminium (Al) in labile and simple organic speciation in natural waters with particular reference to water treatment. The techniques developed were applied to several alum-based coagulation studies of water from the Myponga reservoir. Experiments examined total Al levels as well as the proportion of Al that was bound to natural organic matter (NOM). / The detection of Al was based upon the electrochemical determination of its complex with the ligand 1, 2-dihydroxyanthraquinone-3-sulphonic acid (DASA). The voltammetry of this complex allows the measurement of low levels of Al (LOD of 10 µg/L). This can be achieved by indirect analysis through oxidation by amperometry of DASA (+0.6V vs Ag/AgCl/KCl at a glassy carbon electrode) or by the reduction of the Al-DASA complex through adsorptive cathodic stripping voltammetry (-1.15V vs Ag/AgCl at a mercury film electrode). / An automated flow injection analysis (FIA-Al) manifold was developed based upon the above detection methods. The manifold utilised a number of switching valves, pumps and reactors under computer control. Reductive Al-DASA chemistry at the mercury film electrode to FIA-Al encountered a number of difficulties which prevented its application to real samples. Oxidative amperometry was successfully applied to probe Al levels during water treatment with coagulation. An instream low-level UV lamp, placed between switching valves, allowed Al speciation to be probed by preferentially irradiating different samples. Two Al fractions were thus determined, labile Al- the DASA reactive fraction without UV treatment, and total Al, the DASA reactive fraction processed semi-automatically with a high degree control of the key reaction conditions leading to good reproducibility. / The Al protocol developed was applied to different coagulation experiments with alum. In these experiments, standard and enhanced coagulation conditions were explored with both jar test apparatus and a coagulation/ flocculation pilot plant. This application of the FIA-Al process to the pilot plant allowed the Al levels in treated water to be determined on-line for a wide range of residual Al. / The application of organic matter characterisation techniques enabled further correlation between the Al speciation as derived by the FIA-Al procedure and the character of NOM that binds most readily with Al. Al speciation observed in this study follows the generalised trends observed in other more complex Al studies. During the treatment process, a proportion of Al exists as complex Al polynuclear species and as Al bound to NOM. After the precipitation/ sedimentation process has removed the majority of NOM and colloidal species, the majority of Al exists as the labile form that is free or bound to simple inorganic ions such as hydroxide, fluoride and sulphate. / Thesis ([PhDBiomedicalScience])--University of South Australia, 2004.

The prevalence of the cyanobacterial metabolites: MIB, geosmin and microcystin in drinking water is a major concern to the water industry as these metabolites can compromise the quality of drinking water. Consequently, effective removal of these metabolites from drinking water is paramount. The combination of ozone (O3) and granular activated carbon (GAC) has been shown to be effective for the removal of these metabolites from drinking water. In this study, the ozonation of MIB and geosmin was affected by the character of natural organic material (NOM). In particular, NOM containing compounds of high UV absorbing properties and high molecular weight (MW) resulted in greater destruction of MIB and geosmin due to the formation of hydroxyl (OH) radicals. / Thesis (PhDAppliedScience)--University of South Australia, 2004.
