Lange is a Senior Hydrogeologist with Golder Associates in Sydney, with eleven years academic and professional experience primarily in the field of contaminant hydrogeology. Lange is originally from California, where he earned his BSc in Geological Sciences from the University of California, Santa Barbara, and spent the first three years of his career with a consultancy in San Francisco. He migrated to Australia with his future wife in 2000 as a PhD student at the University of New South Wales, where his research focused on hydrogeochemical processes in landfill leachate. Lange took a consulting role with ERM in 2003, and moved to Golder in 2007. In his spare time, he got married, became a father, became an Australian Citizen, and completed his doctorate (in that order).

Lange has been involved with the IAH NSW committee since 2006, as a Communications Officer the first year and as Committee Chair thereafter. Over the past three years Lange has worked closely with the NSW committee to increase meeting attendance (which now averages 30+ per meeting) and restructure the meeting format to help the committee turn from nearly bankrupt to financially solvent. The stabilised financial position has allowed the NSW committee to apply increased funding towards the stated objectives of the IAH organisation; initiatives include sponsorship of registration and return airfare for one outstanding groundwater research student for the 36th IAH Congress in Japan in October 2008, and assistance with development of a technical workshop in high resolution field investigation techniques. Lange also successfully coordinated the Australian national application for the 2008 Darcy Lecture in conjunction with the national IAH network, which toured all the major cities in Australia in November 2008.

Philip Commander is Principal Hydrogeologist with the Department of Water Western Australia. His 38 year career with the Public Service includes 25 years with the Geological Survey of WA. Philip joined IAH in 1977, is a founder member of IAH in Australia, and has served on the National Committee as Treasurer from 1987 to 1990, as well as involvement with the WA State Branch over many years.

He has stood for re-election to oversee the transition from a state based National Committee to an National Committee with stronger links to the State Branches. He envisages that the National Committee will seek incorporation, which would involve annual elections, and will set up a permanent secretariat, which would facilitate improvements to the website and newsletter.
