Dynamics of PFAS transport in the unsaturated zone: Insight from long-term monitoring of an AFFF-contaminated site

Fri, 25 Sep 2026 15:58:33 +0200

PFAS in the unsaturated zone can remain a long-term source of groundwater contamination. A two-year Danish field study shows that precipitation and infiltration, soil composition and secondary PFAS reservoirs control mobilisation and vertical transport, with distinct behaviour for short- and long-chain PFAS.

Microplastics in groundwater: An updated systematic review of occurrence, hydrogeological controls, methodological challenges, and regulatory gaps

Fri, 25 Sep 2026 15:57:20 +0200

Microplastics are increasingly detected in groundwater, yet their occurrence, transport and environmental relevance remain difficult to assess. A systematic review of 82 field studies from 28 countries demonstrates their presence across a wide range of hydrogeological settings. Large differences in reported concentrations are strongly influenced by inconsistent sampling and analytical methods. Standardised monitoring is therefore essential for developing reliable groundwater quality criteria and future regulatory frameworks.

PFAS and the pollution trap: contested knowledge in environmental justice struggles

Fri, 25 Sep 2026 15:57:33 +0200

PFAS contamination is not only an environmental and health issue, but also a challenge of environmental justice and access to reliable knowledge. Based on 25 documented PFAS conflicts worldwide, this study examines how scientific uncertainty, chemical persistence and information asymmetries shape affected communities. The authors describe how the largely invisible nature of PFAS contamination can delay recognition and regulatory action. The study highlights the importance of combining scientific evidence with the experiences and knowledge of exposed communities.
