Iron Manganese

Iron-related clogging of boreholes, pumps and dripper lines is a significant and costly problem for irrigators worldwide. The primary cause of iron-related clogging is still debated. Previous studies have described complex interactions between biological clogging and inorganic iron/manganese oxide precipitation. This case study examined groundwater bores used for viticulture irrigation in the Limestone Coast region, a highly productive wine growing area in the SE of South Australia. Iron clogging of bore screens, pumps and dripper systems has been a persistent problem in the region and the issue is perceived to be growing, with irrigators suggesting the widespread introduction of iron-related bacteria (IRB) through drilling equipment to be the root cause of the problem. Analysis of the groundwater microbiology and inorganic chemistry found no apparent correlation between the presence of IRB and the clogging status of wells. In fact, IRB proved to be widespread throughout the limestone aquifer. However, a clear correlation could be found between clogging affected bores and the redox potential of the groundwater with the most severely affected bores strongly oversaturated in respect to iron oxide minerals. Elevated dissolved concentrations of Fe(II) thereby tended to be found in deeper bores, which also were generally more recently drilled. Following decades of less than average rainfall, a tendency to deepen bores in response to widespread declines in water levels has been documented for the SE of South Australia. The gradually widening clogging problem in the region is postulated to be related to the changes in climate in the region, with irrigators increasingly driven to rely on deeper, anoxic iron-rich groundwater resources.

Key Features

A case study of the McLaren Vale wine industry is used to challenge four areas of the regulation debate. First, the uniqueness of some of the key features underpinning the periodisations of accumulation regimes and their associated modes of social regulation is questioned. Second, concern is raised over the extent to which ‘new industrial districts’ can really be described as engaging in ‘new’ practices. Third, the importance of local regulatory mechanisms is emphasised. Last, the importance of nonstate, nonlegislative forms of regulation are highlighted.

African students from refugee backgrounds constitute a special group in Australian schools because of their complex lives and previous schooling and life experiences that are unlike most of their non-refugee peers. This chapter draws upon findings from a collaborative, longitudinal case study that sought to understand the education and career pathways of African students from refugee backgrounds from the perspectives of African youth, educators, service providers, and South Australian African community leaders and elders. Qualitative analysis revealed six key influences that shape these pathways: previous schooling; English language skills; Australian schooling challenges and support; family support, academic achievement; and post-school preparation. This chapter presents the case study of a single student that, although unique in its circumstances, is representative of key findings from the larger study. Implications for educational practice are then described with a view to facilitating educational participation and success amongst this particular group of young people.
