UK Unveils First National Plan To Tackle Risks Posed by ‘Forever Chemicals’

The UK government has launched its first national plan to address the risks associated with per- and polyfluoroalkyl substances (PFAS), commonly known as “forever chemicals,” in a move aimed at strengthening environmental protection and public health. Announced on February 3, 2026, by the Department for Environment, Food & Rural Affairs (Defra), the PFAS Plan establishes a coordinated framework involving government agencies, regulators and industry to better understand the sources, spread and long-term impacts of these persistent substances.

PFAS are widely used in manufacturing and certain low-carbon technologies, but growing scientific evidence indicates that their persistence in the environment can pose serious risks to ecosystems and human health, with effects lasting for decades or even centuries.

Although the UK maintains high drinking water standards and PFAS levels in England and Wales are currently within permitted limits, the government plans to consult later this year on introducing a statutory limit for PFAS in public water supplies. The proposed measure would strengthen regulatory oversight and provide a clearer enforcement framework if thresholds are exceeded.

Environment Minister Emma Hardy said the persistence of PFAS presents a long-term challenge that requires decisive, coordinated action. She emphasized that the government will work with regulators, industry and communities to reduce harmful impacts while supporting a transition to safer alternatives.

A key element of the plan is expanded environmental monitoring. For the first time, authorities will assess PFAS contamination in England’s estuaries and coastal waters through enhanced testing of sediments and marine invertebrates. The initiative aims to build a stronger scientific evidence base for future regulation.

The programme also promotes the development of PFAS-free alternatives in consumer products such as hygiene items, food packaging, water-repellent clothing and footwear, sectors where PFAS emissions are significant.

Additional measures include guidance on managing legacy contamination on polluted land, improved industrial handling and disposal practices, expanded soil monitoring in collaboration with the British Geological Survey, and a review of restrictions on PFAS use in firefighting foams. A dedicated public website will also be launched to improve transparency and public awareness.
