In 2016 the National Measurement Institute (NMI) conducted Australia’s second proficiency study for poly- and per-fluoroalkyl substances (PFAS). Twenty-four laboratories participated in this study in which total and linear PFOS and PFOA were analysed in fish, soil and water. A copy of the final report is available.
Proficiency testing assesses the performance of different laboratories and analytical methods by comparing their results for a single sample, and helps provide end-user confidence in overall data quality and reliability of results. NMI hosted a free workshop for end-users of PFAS data (e.g. consultants, regulators, site managers/owners) to discuss the results of the present study, the significance of proficiency study results, the complexities of PFAS analysis, possible needs for future analysis and plans for the next round of proficiency studies. The workshop also included several presentations related to these topics.
