This paper reports on a water quality monitoring program carried out for Wingecarribee Shire Council between March 2002 and July 2004 by University of Wollongong staff and students. Initially 40 sites were sampled on four occasions over three months in a pilot program leading to the selection of sites and parameters for a two year program of monthly monitoring. A range of chemical, physical and biological parameters was measured including nutrients and faecal coliform bacteria on samples collected over the 26 approximately monthly sampling trips. Chlorophyll a, phaeophyton and blue-green algae were also determined over a shorter period. The sampling …

Water quality is a serious environmental concern in the South Coast region of New South Wales as many aspects of human ecology and the economy are dependant on good water quality. Apart from drinking water for residents and visitors, tourism and agricultural productivity rely on good quality water. This paper presents an overview of general issues with regard to the development of water quality assessment procedures and programs, and discusses a number of issues considered important for the region. These include the impacts of increasing urbanisation, industrial activity (including mining), the potential wider use of groundwater and the improved management …
Changes In Tropospheric Composition And Air Quality Due To Stratospheric Ozone Depletion And Climate Change, Stephen R. Wilson, Keith R. Solomon, Xiaoyan Tang

It is well-understood that reductions in air quality play a significant role in both environmental and human health. Interactions between ozone depletion and global climate change will significantly alter atmospheric chemistry which, in turn, will cause changes in concentrations of natural and human-made gasses and aerosols. Models predict that tropospheric ozone near the surface will increase globally by up to 10 to 30 ppbv (33 to 100% increase) during the period 2000 to 2100. With the increase in the amount of the stratospheric ozone, increased transport from the stratosphere to the troposphere will result in different responses in polluted and …

This paper considers issues relating to the measurement of water quality parameters in the laboratory, especially an external (usually commercial) laboratory. Many organisations now use testing laboratories for water quality measurements, a process that has advantages and some limitations. The interaction between the testing laboratory and the organization requiring the data is crucial, and this paper looks at some aspects where a full appreciation of the role of each partner is important. These include limits of detection and reporting, measurement uncertainty, sample storage and preservation times, and various quality control procedures.
