This project determined the ecological effect of coastal wastewater treatment plant (WWTP) outfalls in two different coastal settings. Treated effluent, seawater, and marine sediments were collected from two WWTP outfalls located in South Australia (Glenelg & St Kilda). This is a shallow and retentive receiving environment and may accumulate effluent contaminants. Additionally, sediments were collected from another WWTP outfall in New South Wales (Malabar). This deep-water outfall discharges into a highly dispersive environment and offers a point of comparison for contaminant retention with the outfalls located in South Australia. Work focused on five contaminants that water quality managers had identified in previous NESP MaC work (Project 1.16) as being highly important: nutrients and metals (traditional effluent pollutants); and antibiotics, per- and poly-fluoroalkyl substances (PFAS), and microplastics (contaminants of emerging concern). This record describes the results from the wastewater (effluent) and sea water sampling component of this study. Results from the sediment sampling are described separately by the record 'Sediment sampling data from wastewater treatment plant outfalls' (https://metadata.imas.utas.edu.au/geonetwork/srv/eng/catalog.search#/metadata/7130f946-c629-416e-99be-66ab53e885d7). Data is currently under embargo, to be released in January 2026.

Numerous per- and polyfluoroalkyl substances (PFAS) are of growing concern worldwide, due to their ubiquitous presence, bioaccumulation and adverse effects. Surface waters in the United States have displayed elevated concentrations of PFAS, but so far discrete water sampling has been the commonly applied sampling approach. Here we field-tested a novel integrative passive sampler, a microporous polyethylene (PE) tube, and derived sampling rates (Rs) for 9 PFAS in surface waters. Three sampling campaigns were conducted, deploying PE tube passive samplers in the effluent of two wastewater treatment plant (WWTP) effluent sites plants (WWTPs) and across Narragansett Bay (RI, US) for one month each in 2017/2018. Passive samplers exhibited linear uptake of PFAS in the WWTP effluents over 16-29 days, with in-situ Rs for nine PFASs ranging from 10 mL day-1 (PFPeA) to 29 mL day-1 (PFOS). Similar sampling rates of 19 ± 4.8 mL day-1 were observed in estuarine field deployments. Applying these Rs values in a different WWTP effluent predicted dissolved PFAS concentrations mostly within 50% of their observations in daily composite water samples, except for PFBA (where predictions from passive samplers were 3x greater than measured values), PFNA (1.9), PFDA (1.7) and PFPeS (0.1). These results highlight the potential use of passive samplers as measurement and assessment tools of PFAS in dynamic aquatic environments.
