refereed paper contaminants of concern water MAY 2012 81 The Authors Gayle Newcombe (email: Gayle.Newcombe@ sawater.com.au) is Research Leader, Applied Chemistry at the Australian Water Quality Centre. Gayle has worked in the water industry for 23 years leading research into the management of cyanobacteria and, more recently, nitrosamines in drinking and recycled water. Jim Morran is Senior Research Scientist for water treatment at the South Australia Water Corporation with over 30 years' experience in research and development in water treatment processes, with a particular focus on natural organic matter, disinfection processes and disinfection by-products. Julie Culbert is a Senior Research Officer with the Australian Water Quality Centre and is involved with developing and applying analytical methods for the analysis of trace organic contaminants in water.
