Artificial groundwater recharge – A shortcut for harmful poly- and perfluoroalkyl substances (PFASs) into groundwater systems and drinking water supplies – Can we avoid this?
Short description
Emerging contaminants in aquatic systems are of increasing concern and of relevance to the Swedish Environmental Protection Agency, which aims to provide clean drinking water and a non-toxic environment. Poly- and perfluoroalkyl substances (PFASs) are a group of about 5000 persistent contaminants found in a variety of products, that cause severe long-term health effects at daily intake rates in the ng/L range. This project aims at understanding the input of PFASs into groundwater systems and drinking water supplies as well as at improving the attenuation capacity for PFASs during managed aquifer recharge (MAR).

October 8th 2024, FRAM seminar on PFAS in Swedish drinking waters – challenges and solutions in Gothenburg, Sweden
Philipp Wanner opened the FRAM seminar on PFAS in Swedish drinking waters by showing a Swedish perspective on PFAS in drinking water as well as ongoing research efforts. He was followed by presentations from Yiyi Xu from the School of Public Health and Community Medicine at Sahlgrenska Academy and Jenny Ivarsson from the Swedish Chemicals Agency giving insights into health effects of PFAS and a regulatory perspective.
FRAM is the Centre for Future Chemical Risk Assessment and Management Strategies in Gothenburg and hosting regular seminars on ongoing research themes.

Presentation on PFAS at the INFRAS Monday education
Tabea Mumberg gave, together with Lars Brunken from Karolinska Institutet (Stockholm, Sweden), an online presentation for the Swiss company INFRAS during their Monday education. They presented and discussed PFAS, their fate into the environment as well as their risk assessment and regulation with a lot of great questions from the audience. The session was hosted and initiated by Caspar Esche from INFRAS.

February 27th-28th 2024, SIDWater meeting at Gothenburg University, Sweden
Both Philipp Wanner and Tabea Mumberg participate in a related project called “SIDWater – Sustainable innovative drinking water treatment solutions” lead by the Swedish University of Agricultural Sciences (SLU). This year’s project meeting was hosted at the University of Gothenburg. Participants from SLU, Chalmers University of Technology, Lund University, Uppsala University, Uppsala Vatten och Avfall, Sydvatten, Stockholm Vatten och Avfall, and Norrvatten joined.
This were two great days full of interesting discussion and planning future studies and experiments!

Half year set of water samples extracted
After visiting SLU for a course on organic micropollutants the past weeks, further water samples from two infiltration sites were again extracted by solid-phase extraction and prepared for analysis of poly- and perfluoroalkyl substances (PFASs) at the Swedish University of Agricultural Sciences (SLU).
PFASs concentration analysis will be conducted by ultra-performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS) to get an overview of PFASs concentration changes during surface water infiltration. Further water quality parameters already are assessed and will be compared to the measured PFASs concentrations.
November 2022
Analysis of the first water samples
This week, the first water samples from two infiltration sites were extracted and prepared for analysis of poly- and perfluoroalkyl substances (PFASs) at the Swedish University of Agricultural Sciences (SLU). It will be great to receive the very first data in this project! The PFASs were recovered from the water samples by solid-phase extraction and PFASs concentration analysis will be conducted by ultra-performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS).
