Key takeaway
What This Development Means
The Dutch government has reiterated that PFAS are treated as “very concerning substances” and that emissions must be prevented where possible and otherwise minimised. Permitting decisions hinge on case-by-case assessment, including water quality impact tests and enforcement frameworks.
How do Dutch authorities decide whether PFAS discharges can be permitted?
The response explains that PFAS are addressed within the “very concerning substances” policy framework. Authorities assess each application individually, including whether best available techniques are used and whether an impact test indicates concentrations remain within applicable health and environmental limits.
What does “polluter pays” mean in practice for PFAS discharges?
The ministry points to discharge and treatment levies for direct and indirect releases, where charges reflect the pollution load. If additional treatment is required to manage a company’s wastewater, those extra costs can be passed on to the company. Separate civil and administrative routes may apply for illegal discharges.
Source basis: Ministry of Infrastructure and Water Management (Netherlands), Parliamentary Q&A on PFAS discharges (27 January 2026)
The Dutch Ministry of Infrastructure and Water Management has issued a detailed response to parliamentary questions on PFAS discharges, prompted by concerns about permits for industrial facilities and findings of PFAS contamination linked to waste and recycling operations. The letter, dated 27 January 2026, explains how the Netherlands applies its existing permitting and enforcement framework to per- and polyfluoroalkyl substances.
PFAS Treated As “Very Concerning Substances” With A Minimisation Duty
The ministry states that understanding of PFAS harmfulness has increased and that PFAS are widely present in the environment. PFAS fall within the “very concerning substances” (ZZS) category, where the policy starting point is that emissions should be prevented wherever possible and, where prevention is not possible, reduced to the minimum. The response emphasises that risk cannot be assumed solely from the presence of a PFAS emission, because acceptability depends on factors such as the intrinsic hazard of the substance, emission magnitude, local conditions and cumulative upstream inputs.
Permit Decisions Rely On Case-By-Case Assessment And Water Quality Testing
In addressing a permit application involving a proposed PFAS discharge limit of 5 kg per year, the ministry explains that the competent authority assesses compliance with applicable ZZS rules, including minimisation and the use of best available techniques. It also relies on an “immissietoets”, a water quality impact test, to evaluate expected concentrations in receiving waters against relevant health and environmental limit values, including for drinking water abstraction points.
The ministry notes that, where all legal conditions are met, a permit may not be refusible under the current legal framework. It also references the role of enforcement signals and oversight in ensuring that permitting assessments are carried out correctly.
Cost Allocation And “Polluter Pays”
On costs, the response reiterates that the “polluter pays” principle is embedded in Dutch and EU law. It points to levies for indirect discharges to wastewater treatment and for direct discharges to surface waters, with charges tied to pollution load. Where additional treatment is required to manage a company’s wastewater, those extra costs can be charged back to the company, alongside the firm’s own investment obligations to minimise emissions.
Summary
The letter underlines that PFAS permitting in the Netherlands is primarily an implementation question: minimisation duties, best available techniques and water-quality impact testing determine what is allowable in practice. For operators, the message is clear: robust data, defensible impact assessments and demonstrable minimisation measures are essential to sustain permits and stakeholder confidence.
