Abstract/Summary Two perfluoroalkyl chemicals (PFCs), perfluoroctanoic acid (PFOA) and perfluorooctanesulfonate (PFOS), have been detected widely at low levels in biota and humans. Secondary sewage treatment plants (STPs) do not effectively remove these compounds; hence STP effluents are recognized point sources to the aquatic environment. Here we sampled water from various stages of an advanced water treatment plant, utilizing microfiltration, reverse osmosis and advanced oxidation, and assessed the removal of 15 PFCs in the system. The plant studied takes effluent from several STPs, producing up to 66 ML/day of purified recycled water. Grab samples were collected at various stages of the treatment train. Analysis showed PFCs to be present in the influent at concentrations of 78.9 – 151.2 ng/L (Σ15PFCs), but almost completely removed by reverse osmosis. PFCs were detected above reporting limits at 4 of the 7 sampling points. This work provides a measure of PFCs in Australian recycled water, contributes data on the fate of these compounds in advanced water treatment, and illustrates their efficient removal by RO under operational conditions. Analytical variability appeared to be less than variability between sampling events, indicating in future composite samples or flow proportional sampling will improve data quality.
