Research project CHEMPACT - Status of CHEMical emissions via wastewater treatment plant effluents and imPACT

The project compiles and synthesizes data on micropollutants in wastewater emitted in the Baltic Sea drainage basin and reviews effects associated with chemicals in wastewater in the Baltic Sea catchment.

CHEMPACT aims to contribute to minimizing risks for human health and the environment arising from chemicals emitted in the urban areas and transferred to the aquatic environment via WWTPs in the Baltic Sea catchment. We will compile published data on measured concentrations of contaminants in wastewater, analyse and visualize the data and review the literature on associated ecotoxicological effects. We will communicate the results and conclusions to relevant stakeholders.

Please contact Emma Undeman, emma.undeman@su.se, if you are interested in the CHEMPACT database.

Policy brief: Call for better management of micropollutants in wastewater

Urban wastewater treatment plants are important collection points for many chemical contaminants, often called micropollutants, which are widespread in the aquatic environment. Currently, this issue is not being sufficiently addressed by regional policy and EU-wide legislation. The EU’s Zero Pollution Ambition, the Chemicals Strategy for Sustainability and the likely revision of the Urban Wastewater Treatment Directive now provide opportunities to address this issue. Measures to prevent the emissions of micropollutants via wastewater treatment plants are needed both up- and downstream, to ensure policy coherence between EU water and chemicals legislation.

New study highlights need for monitoring of micropollutants in urban wastewater

Land-based pollution and maritime activities puts the coastal zones of the Baltic Sea under a high anthropogenic pressure. In a new study on micropollutants in wastewater emitted in the Baltic Sea catchment, the need for broad scope monitoring of micropollutants in wastewater around the Baltic Sea is highlighted.
