Centring Wiannamatta (mother place): the story of the environmental persistence of tri-butyl phosphate within a legacy waste site

Tri-butyl phosphate (TBP) is an organic chelate that was used in the 1960s at the Lucas Heights Laboratories of the Australian Atomic Energy Commission (AAEC) before being disposed in sealed containers in trenches at a nearby waste site across a discrete 8-year period. The first study investigating whether TBP was still present at the site was conducted in 2016, which detected low levels of TBP. The aim of the current study was to assess whether the TBP concentrations had changed and, if so, wha
