The Expert Panel has established two working groups to collaborate and provide an additional source of informed scientific advice to the Chair of the Expert Panel – a Water Working Group (WWG) and a Risk Assessment Group (RAWG).
Water Working Group
The WWG has been established to assist in developing the NSW Government’s response to the Department of Defence in relation to investigations to characterise and manage its offsite PFC contamination resulting from historical usage of PFC containing firefighting foams at the Williamtown RAAF Base.
Chaired by independent Expert Panel member, Dr Will Glamore, the WWG will provide advice on what additional sampling needs to be undertaken by Department of Defence and/or State Government agencies to inform the development of the comprehensive Human Health Risk Assessment (HHRA). This includes the development of hydrological and hydrogeological modelling to improve the understanding of potential migration pathways for PFCs in the environment and help to identify potential human health and environmental receptors.
Risk Assessment Working Group
The RAWG has been established to provide expert advice to the Chair of the Expert relating to the potential risk pathways associated with the off-site migration of PFOS and PFOA. The RAWG will also provide ongoing advice to the Department of Defence while they undertake the Human Health Risk Assessment. This includes advice on biota sampling and community land use information that needs to be undertaken and assistance in determining immediate exposure pathways to land and water users in the vicinity of RAAF Williamtown.
The RAWG is co-chaired by Expert Panel member Dr Ben Scalley, NSW Health Director of Environmental Health.
