Europe accelerates action on water resilience, PFAS and industrial emissions
Europe’s water and emissions rules are changing: what operators need to know.
EU and UK measures are strengthening requirements for monitoring, source control and the treatment of PFAS and industrial waste gases. At the same time, climate pressures, prolonged drought, pollution and competing demand are driving water security higher up the European regulatory agenda. This is increasing scrutiny of PFAS, pesticides, pharmaceuticals, microplastics and other emerging contaminants, alongside the need to protect increasingly constrained water resources.
The European Commission’s Water Resilience Strategy has three broad objectives: restoring and protecting the water cycle from source to sea; building a water-smart economy; and ensuring access to clean and affordable water. The strategy calls for stronger implementation of existing freshwater legislation, wider adoption of water-efficient practices and green infrastructure, modernisation of water assets and action on pollutants in drinking water, including PFAS.
For operators, the future state is broader monitoring, stronger source control and greater scrutiny of discharge quality and contaminant management, alongside growing demand for treatment systems that deliver reliable long-term performance and enable the safe reuse of water.
TFA: a growing challenge for EU water monitoring and treatment
The EU’s updated rules for surface water and groundwater entered into force in May 2026. They amend the Water Framework Directive, Groundwater Directive and Environmental Quality Standards Directive, expanding the lists of regulated pollutants and strengthening monitoring across Member States.
The revised framework includes additional PFAS and trifluoroacetic acid (TFA), highly persistent and mobile breakdown product of certain PFAS, into the scope of surface-water assessment. It also introduces a method for considering the combined impact of pollutants rather than assessing every substance in isolation.
Member States must transpose the new requirements into national law by 22 December 2027. The legislation then provides staged compliance deadlines extending into the 2030s.
What this means for operators
- Broader monitoring across surface water and groundwater
- More consistent digital reporting across Member States
- Greater pressure to identify and control emission sources
- Increased focus on preventing pollution as well as remediating legacy contamination
- Growing demand for treatment technologies suited to persistent and highly mobile compounds
TFA presents a particular technical challenge. As an ultra-short-chain PFAS, it is highly mobile in water and generally more difficult to adsorb than many longer-chain PFAS. Standard activated carbon systems designed for longer-chain compounds may therefore provide limited TFA removal or require substantially different operating conditions.
This does not mean activated carbon should be dismissed without assessment. It means media choice and system design must be based on the actual water matrix, target concentration, competing organics, contact time and required treatment outcome.
PFAS remediation and monitoring
Restrictions on future use address only part of the challenge. Decades of historic production, use and disposal have left PFAS in soils, groundwater, surface water, industrial sites, military facilities, airports, fire-training areas and landfills.
European policy continues to emphasise the polluter-pays principle, under which those responsible for contamination should bear the cost of managing it. The European Commission is also seeking to stimulate innovation in PFAS detection, treatment and remediation.
For site owners and operators, understanding likely sources, pathways, receptors and target compounds is fundamental to selecting a treatment strategy and demonstrating improvement. Activated carbon is a proven and widely used treatment option for removing PFAS and other contaminants in remediation projects. Effective treatment depends on selecting the appropriate carbon and system configuration for the contaminant profile, concentration, flow rate, water chemistry, competing substances and required treatment outcome.
The UK publishes its first national PFAS Plan
In February 2026, the UK Government published its first national PFAS Plan. The plan establishes an overarching UK direction, but the scope of individual actions varies. The plan addresses three connected priorities: improving understanding of PFAS sources; tackling the pathways through which PFAS reach people and the environment; and reducing continuing exposure.
Monitoring and evidence
The programme includes continued expansion of PFAS monitoring and the national evidence base. In England, the Environment Agency is expected to publish its PFAS geographic prioritisation map by the end of 2026, followed by an interactive website planned for 2027. The purpose is to help identify areas where further investigation or action should be prioritised. Monitoring activity is also being strengthened in Scotland and Wales, with delivery led by the relevant governments and environmental regulators.
Contaminated land and legacy pollution
The UK programme recognises that legacy contamination may affect former industrial facilities, military sites, firefighting areas, landfills, groundwater and watercourses. For England, work includes clearer guidance for local authorities managing potentially contaminated land under Part IIA of the Environmental Protection Act 1990. Wider technical guidance on legacy PFAS contamination is planned by 2027, with the aim of supporting more consistent site investigation, risk assessment and remediation across relevant regimes.
Industrial emissions and waste
The plan provides for cross-sector guidance to help regulators and permitted industries reduce PFAS emissions and improve handling, monitoring and disposal. Technical work during 2026–27 is expected to consider available treatment and destruction routes, environmental permitting and the management of PFAS-containing waste. For industry, this points towards greater transparency about PFAS use and releases, closer examination of permits and more scrutiny of how contaminated waste, spent treatment media and landfill leachate are handled.
Drinking water and chemicals regulation
The UK Government intends to consult on a statutory PFAS limit for public water supplies in England. The detail and timing of any new standard remain subject to consultation. Under UK REACH, the government is considering restrictions on PFAS in firefighting foams. Its wider reform programme also aims for faster and more efficient chemicals protections, with closer alignment to major trading partners, notably the EU, by December 2028.
EU chemical-sector waste-gas deadline approaches
The EU’s Best Available Techniques conclusions for common waste-gas management and treatment systems in the chemical sector were published in December 2022. Under the Industrial Emissions Directive framework, affected installations are expected to align permit conditions and operations with the relevant requirements within four years, making December 2026 a critical milestone. The conclusions cover pollutants including volatile organic compounds, benzene, halogenated compounds and acidic gases such as hydrogen chloride and hydrogen sulphide.
Compliance is about more than installing treatment equipment. Operators may need to demonstrate control through:
- A comprehensive waste-gas inventory
- Appropriate continuous or periodic monitoring
- Performance testing against permit conditions
- Management of variable flows and contaminant concentrations
- Preventive maintenance and operating controls
- Documentation showing sustained treatment performance
Older treatment systems may struggle with tighter emission levels, particularly where gas composition, concentration or flow varies over time. Reviewing treatment capability is essential to characterise the stream, test treatment options and plan upgrades before a compliance problem emerges.
How Puragen can help
Puragen can help operators prepare for changing permit conditions while maintaining reliable and cost-effective treatment.
PFAS
PFAS treatment performance depends on the PFAS profile, chain length, water chemistry or air emission profile, competing organic matter, contact time, hydraulic conditions and treatment objective.
Puragen can help operators:
- Review the target compounds and operating conditions
- Select activated carbon media suited to the application
- Evaluate existing system configuration and treatment capacity
- Plan laboratory or pilot testing where appropriate
- Develop a carbon-management and replacement strategy
- Consider the handling of spent media as part of the full treatment lifecycle
Air Treatment
Puragen’s VOCSorber® mobile carbon filters provide a flexible treatment option for industrial gas streams. Equipment and activated carbon media can be matched to the contaminant profile and operating conditions, supporting both planned treatment and situations where additional capacity is required.
Reactivation
Puragen’s thermal reactivation service can help recover value from spent carbon, reduce the demand for virgin material and lower waste and lifecycle costs where the carbon and adsorbed contaminants are suitable for reactivation.
PFAS-laden spent carbon is traditionally sent to landfill or hazardous incineration – simply shifting the contamination risk rather than eliminating it. Puragen’s advanced circular treatment approach changes this. We deliver both the effective capture and the permanent destruction of PFAS thought enhanced reactivation, which destroys and mineralises PFAS. Reactivated carbon can be safely reused in ongoing treatment, significantly reducing waste and environmental impact.
