This record provides an overview of the NESP Marine and Coastal Hub project "Ecological outcomes of wastewater discharges in contrasting receiving environments". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Australia’s Waste Policy Action Plan, Threat Abatement Plan for the impacts of marine debris and Australia’s One Health Master Action Plan all refer to the need for emerging pollutants to be incorporated into contaminant guidelines. Wastewater treatment plants currently report on a limited number of contaminants and lack consistent testing requirements. NESP MaC Scoping Study 1.16 has determined there is a clear and consistent need for data on environmental concentrations of emerging contaminants and an assessment of their impact on ecological communities. This project aims to determine the concentration of emerging pollutants in different wastewater outfall settings, and assess where environmental impacts are greatest. It will also continue to collate, analyse and maintain the information from Water Treatment Authorities on outfall flows, pollutant concentrations and loads and presented annually within the National Outfalls Database. Outputs • Measures of CEC (contaminants of emerging concern) in water samples taken from outfall sites [dataset] • Final project report [written]

This record provides an overview of the NESP Marine and Coastal Hub scoping study - "Research needs for assessment and monitoring of nutrients, chemicals and antimicrobials in the marine environment". No data outputs were generated by this project. -------------------- Water quality can be impacted by a large suite of chemical and microbiological contaminants introduced from a variety of sources. There are a number of emerging contaminants and broad ranges of point sources, including a variety of chemical (e.g. heavy metals, pharmaceuticals, pesticides, nutrients) and microbiological (e.g. pathogens, antibiotic resistant microbes) contaminants that are discharged in sewage, stormwater, estuarine flows and industrial wastes. This project will involve a desktop scoping study to collate relevant datasets and current water quality monitoring goals and activities; engage with key stakeholders through workshops, interviews, and surveys to further define priorities; and conduct a risk assessment to assess impacts to marine and coastal water quality. This project will deliver a clear framework for highlighting knowledge gaps, future research directions and water quality management priorities. Outputs • Final technical report with analysed data, including survey outcomes and a short summary of recommendations for policy makers of key findings [written] ---no data outputs were generated by this project---

This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2024 project "Environmental concentrations of emerging contaminants in coastal stormwater". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Australia’s Waste Policy Action Plan, Threat Abatement Plan for the impacts of marine debris and Australia’s One Health Master Action Plan all refer to the need for emerging pollutants to be incorporated into contaminant guidelines. A scoping study conducted by NESP MaC Hub in 2022 (Project 1.16) determined there is a clear and consistent need for data on environmental concentrations of contaminants of emerging concern (CECs) and an assessment of their impact on ecological communities. To build an evidence-based understanding of the environmental concentrations of these contaminants and their ecological significance in Australian coastal waters, NESP MaC Project 2.4 was co-designed with end-users to determine environmental concentrations and potential ecological effects at selected wastewater treatment plant outfalls. In 2023, end-users stated a need for improving the temporal and spatial resolution of the current project. Project 2.4 used outputs of oceanographic simulations and other information to identify a small set of locations for sampling that are representative of a range of receiving water contexts. Spatial surveys of contaminants of emerging concern (CECs) in water and sediments were undertaken during the dry period to limit the potential for stormwater inputs, and only one time period was sampled. An implicit assumption of the sampling design was that stormwater also contains CECs and could confound the assessment of contaminants in wastewater. This project (4.22) is an extension of Project 2.4 and will determine the concentration of emerging pollutants in coastal stormwater, and in wastewater treatment plant (WWTP) effluent, and do so on a seasonal basis. Sampling will be undertaken in two key locations: Gamay (NSW) and Glenelg (South Australia). These are the same locations sampled in Project 2.4 (with a focus on WWTPs) which will enable the concentrations of CECs to be compared at stormwater locations. Outputs • Updates to the National Outfall Database for 2022/23, including proposed new attributes for collection [dataset] • Data from Gamay (Botany Bay) NSW including (1) contaminant levels in water and sediments (2) physico-chemical data; (3) microbial community and genetics composition of water and sediments [dataset] • Timeseries (seasonal) CEC data from wastewater effluent at Glenelg beach area (SA) [dataset] • [Possible] High-resolution temporal CEC data from a stormwater event in St Vincents Gulf [dataset] • Final project report [written]
