Dr Paul Bertsch is the Science Director of Land and Water at CSIRO Ecosciences Precinct in Dutton Park, Brisbane, QLD. "Well the big turning point for the whole scientific community, and I know my colleague in CSIRO really took notice as well, would be 2001." Paul says the CSIRO has been mainly involved in looking at the fate and transport of PFAS contaminants in the environment. CSIRO are interesting in developing models to predict the transport. Developing models to predict how it's partitioned in soil, how it moves in groundwater, and then how it is taken up by eco receptors. He says PFAS is a significant global challenge. Paul said he "would really like to see a future where science would inform policy in a way that is transparent to not only to government but also to community."
