Brooke A. Swaffer undertook this research as part of a Ph.D. begun in 2008, in recognition of considerable knowledge gaps concerning a regionally significant karst groundwater system in southern Australia. Graduating with first class honors in 2005, Swaffer has been employed with the state water utility since, and tasked with providing scientifically underpinned evidence of water quality and quantity impacts in groundwater and surface water supplies.
