PFAS & Microplastics Switzerland 2026: Limits & Rules

What is the PFAS limit in Swiss drinking water in 2026? Under the Ordinance on Drinking Water (TBDV), the values currently in force are individual limits of 0.3 ug/l each for PFOS and PFHxS and 0.5 ug/l for PFOA. Stricter sum limits aligned with the EU are planned for around 2027. The rest of this article sets out the full picture: which uses are restricted, where the EU REACH process stands, where microplastics in Swiss waters come from, and which consumer steps actually work.

PFAS and microplastics turn up in more Swiss headlines every year: trace PFOS in water samples, fresh FOEN reports on tyre wear, debates over firefighting foams in industry and emergency services. If you want to understand what applies now and what changes by 2027, you do not need medical advice; you need a clean read of the facts from the responsible federal offices.

Key Takeaways

• Drinking water (TBDV, in force): individual limits of 0.3 ug/l each for PFOS and PFHxS and 0.5 ug/l for PFOA. New EU-aligned sum limits are planned for around 2027 (0.1 ug/l for the sum of 20 PFAS; 0.02 ug/l for the sum of four).
• AFFF firefighting foams: PFAS foam in portable fire extinguishers may no longer be placed on the market from 23 October 2026; alcohol-resistant PFAS foams follow on 23 April 2027; the transition period for all PFAS-containing devices ends 31 December 2030 (ChemRRV/ORRChim, aligned with EU Regulation 2025/1988).
• Microplastics: the FOEN estimates around 14,000 tonnes of plastics enter Swiss soil and water per year; tyre wear (about 8,100 tonnes) is by far the largest single source.
• EU REACH universal PFAS restriction: the RAC adopted its final opinion on 2 March 2026 and the SEAC agreed its draft opinion on 10 March 2026; a final Annex XVII entry is not expected before 2027. Switzerland transposes steps via ChemRRV/ORRChim.
• Consumer side: BDIH, NaTrue or Ecocert certified cosmetics; stainless steel or cast iron rather than damaged non-stick pans; glass containers rather than grease-resistant packaging.

PFAS and Microplastics: Definitions and the Swiss Context

What PFAS are and why they are called forever chemicals

PFAS stands for per- and polyfluoroalkyl substances. The family covers several thousand compounds that share one property: extremely stable carbon-fluorine bonds that barely degrade in nature. That is why PFAS are called forever chemicals.

In the human body, well-studied PFAS such as PFOA and PFOS have half-lives of several years. The FOEN (Federal Office for the Environment, BAFU) and the FSVO (Federal Food Safety and Veterinary Office, BLV) track PFAS in Swiss soils, waters and food through the NAQUA groundwater programme and cantonal monitoring.

Typical historical uses:

• Non-stick coatings on pans (PTFE/Teflon)
• Water-repellent outdoor clothing and gear (DWR treatments)
• Food packaging with grease or moisture barriers
• AFFF firefighting foams
• Electroplating, semiconductors, medical devices and construction chemistry

Microplastics: definition, sources, Swiss figures

Microplastics are plastic particles smaller than 5 mm. The FOEN distinguishes primary microplastics (deliberately added, such as older cosmetic microbeads) from secondary microplastics (from the abrasion and breakdown of larger plastics).

According to the FOEN meta-study on plastics in the environment, Swiss plastic emissions run to roughly 14,000 tonnes per year into soil and water, of which tyre wear (around 8,100 tonnes) is by far the largest single source. Other relevant sources:

• Synthetic textiles (fibre shedding in the wash)
• Cosmetics and cleaning products containing microplastics (declining because of EU restrictions)
• Construction and coatings (paints, facade renders)
• Plastic packaging waste that fragments over time

Drinking Water and Food: What Applies in 2026

Swiss PFAS drinking water limits

The benchmark is the FDHA Ordinance on Drinking Water and Water in Bathing and Shower Facilities (TBDV/OPBD). The limits currently in force are individual values, not a single sum value:

Substance	Limit (in force)
PFOS	0.3 ug/l
PFHxS	0.3 ug/l
PFOA	0.5 ug/l

Two stricter sum-based limits are planned, expected to take effect around 2027 in step with the EU Drinking Water Directive 2020/2184:

Parameter	Planned limit (~2027)
Sum of 20 selected PFAS	0.1 ug/l
Sum of four (PFOA, PFNA, PFHxS, PFOS)	0.02 ug/l

Key points:

• A limit is a safety threshold, not a neutral value. If a sample exceeds it, the utility must act (source change, activated-carbon filtration, blending).
• In the large majority of Swiss networks, PFAS in tap water stay well below the limits. Point exceedances have been reported in regions with industrial or AFFF legacy contamination.
• Current values for your municipality can be requested from your water utility or cantonal laboratory.

PFAS in food: the EFSA TWI as reference

For food, the Foodstuffs Act (LMG) and the FDHA Contaminants Ordinance apply. In 2020 the European Food Safety Authority (EFSA) set a tolerable weekly intake (TWI) of 4.4 ng/kg body weight per week for the sum of PFOA, PFOS, PFNA and PFHxS. Swiss authorities use this as their reference.

Main intake sources per EFSA assessments:

• Fish (especially freshwater fish from affected catchments)
• Eggs and meat
• Drinking water
• Fruit, vegetables and cereals from affected soils

Microplastics in food: research rather than limits

For microplastics in food there are currently no binding limits in Switzerland or the EU. Studies have detected microplastics in honey, table salt, mineral water and beer; the health effects in humans are still under investigation. The FOEN and FSVO follow EU work; no short-term limit is announced.

Swiss Action Plan and Bans: AFFF, Cosmetics, REACH

FOEN PFAS action plan and ChemRRV/ORRChim

In 2024 the FOEN, together with other federal offices (FSVO, FOPH, ARE), published a PFAS action plan focused on:

1. Cutting PFAS emissions at the source (products, industry)
2. Remediating known contaminated sites (AFFF training grounds, legacy galvanising sites)
3. Strengthening monitoring in water, soil, food and sewage sludge
4. Swiss participation in international PFAS regulation (REACH, Stockholm Convention, OECD)

Binding restrictions run through the Chemical Risk Reduction Ordinance (ChemRRV/ORRChim), which already bans individual PFAS uses and transposes EU restrictions step by step.

AFFF firefighting foams with PFAS

PFAS-containing firefighting foams (notably AFFF) are being phased out. The bans on PFOS, PFOA, C9-C14 perfluorocarboxylic acids and PFHxS in foams above defined mass thresholds are already in force under Annex 1.16 ChemRRV. With the late-October 2025 amendment, aligned with EU Regulation 2025/1988, the timeline tightens:

Deadline	What changes
23 October 2026	No more placing on the market of PFAS-containing foam in portable fire extinguishers
23 April 2027	Ban on alcohol-resistant PFAS foams (for example for solvents)
31 December 2030	End of the transition period; all PFAS-containing foam devices must be replaced or disposed of

Fire services and industrial operators are switching to fluorine-free alternatives (F3, Fluorine-Free Foam). The reason is direct: AFFF deployments are among the largest point sources of PFOS/PFOA in soil and groundwater, with documented contamination near airfields, fuel terminals and firefighting training grounds.

Microplastics in cosmetics: EU restriction since October 2023

The EU microplastics restriction under REACH (Regulation (EU) 2023/2055) bans intentionally added microplastics in a series of products from 17 October 2023, with staged transition periods. Switzerland transposes the restriction via ChemRRV/ORRChim, so the same categories are affected.

Product category	Ban / deadline
Loose glitter and microbeads (rinse-off)	Banned since 17.10.2023
Microbeads in rinse-off cosmetics (scrubs)	Ban in force, transition expired
Rinse-off cosmetics with residual polymers	Phased through 2027
Rinse-off skincare	Through 2027
Make-up and lip products	Through 2035
Performance infill for artificial turf	Ban effective 17.10.2031 (8-year transition)

Pure PFAS film-formers fall under separate restrictions; the EU REACH universal restriction (next section) will add further coverage.

EU REACH universal PFAS restriction

In January 2023, Germany, the Netherlands, Denmark, Sweden and Norway submitted a proposal to the ECHA for a universal PFAS restriction covering around 14,000 substances. It is the broadest restriction ever proposed under REACH. The process has now reached its decisive phase:

• 2 March 2026: the Risk Assessment Committee (RAC) adopted its final opinion, supporting a broad restriction.
• 10 March 2026: the Socio-Economic Analysis Committee (SEAC) agreed its draft opinion, backing targeted derogations where alternatives are not yet available (for example certain medical devices, semiconductors and personal protective equipment).
• A 60-day public consultation on the SEAC draft ran until 25 May 2026; the SEAC final opinion is expected by the end of 2026.
• The European Commission then prepares a draft restriction decision with EU member states. A final Annex XVII entry is unlikely before 2027.

On the Swiss side, once an EU restriction enters into force, the FOEN reviews transposition via ChemRRV/ORRChim, with stakeholders (Scienceindustries, Swissmem, FH Switzerland) involved.

Consumer Protection: What You Can Do

We give no medical recommendations. The steps below build on FOEN, FSVO and consumer-protection guidance (SKS, Konsumentenforum, FRC, ACSI).

Cosmetics and personal care

• Products certified BDIH, NaTrue or Ecocert exclude PFAS and microplastics under their standards.
• Read INCI lists: "PTFE", "Perfluoro...", "Polyfluoro..." or "Fluoropolymer" indicate PFAS. For microplastics, watch for "Polyethylene", "Polypropylene", "Nylon-12", "Acrylates Copolymer" or "Polymethyl Methacrylate".
• Apps such as CodeCheck (Switzerland) or ToxFox (BUND, Germany) let you scan barcodes in store.

Pans, packaging and household

• Replace non-stick pans once the coating is damaged (scratches, chips). Intact pans at moderate heat remain acceptable for home use per FSVO/BfR assessments.
• Alternatives: stainless steel, cast iron, carbon steel or ceramic coatings (different material profiles).
• Storage: glass or stainless steel containers; avoid grease-resistant take-away wrappers where you can.
• Baking: unbleached parchment paper or silicone baking mats (no PFAS).

Drinking water

• Swiss tap water meets the TBDV/OPBD and is safe for daily use in 2026.
• If you live in the catchment of a historical contamination (for example an AFFF site), ask your water utility for current values.
• Additional filtration: activated-carbon filters can reduce some PFAS, with effectiveness varying by chain length. Choose a filter with independent testing (NSF/ANSI 53/58 "PFOA/PFOS reduction").

Outdoor gear

Many Swiss and international brands (Patagonia, Mammut, Vaude) have announced or implemented PFC-free DWR treatments. Look for "PFC-frei" or "PFC-free" labels; for re-proofing at home, use PFC-free products.

How This Connects to Your Household Budget

PFAS and microplastics sit next to several everyday Swiss topics. For the framework of the health system, see our health insurance comparison and the 2026 health insurance premiums. For other 2026 environment and mobility rules, our explainers on the CO2 sanction on vehicle registration and electricity prices in Switzerland 2026 cover what changes for households and drivers. Local water utilities publish annual water-quality reports that may include PFAS measurements.

Frequently Asked Questions

What is the PFAS limit in Swiss drinking water?

Under the TBDV/OPBD, the limits in force are individual values: 0.3 ug/l each for PFOS and PFHxS and 0.5 ug/l for PFOA. Stricter sum limits aligned with the EU are planned for around 2027 (0.1 ug/l for the sum of 20 PFAS and 0.02 ug/l for the sum of four). Cantonal laboratories verify compliance; current values for your municipality can be requested from your water utility.

Are PFAS widespread in Swiss tap water?

Modern methods detect PFAS even at very low concentrations. In the large majority of Swiss networks, values stay well below the TBDV/OPBD limits. Point exceedances have occurred in regions with historical AFFF or industrial loading, where utilities take corresponding action.

Are AFFF firefighting foams with PFAS banned in Switzerland?

They are being phased out. Bans on PFOS, PFOA, C9-C14 PFCAs and PFHxS in foams above mass thresholds already apply. From 23 October 2026, PFAS foam may no longer be placed on the market in portable extinguishers; alcohol-resistant PFAS foams follow on 23 April 2027; and the transition period for all PFAS foam devices ends on 31 December 2030. Operators switch to fluorine-free alternatives.

Where does the EU REACH PFAS restriction stand?

A proposal for a universal restriction covering around 14,000 substances has been before the ECHA since January 2023. The RAC adopted its final opinion on 2 March 2026 and the SEAC agreed its draft opinion on 10 March 2026, with the SEAC final opinion expected by the end of 2026. A final Annex XVII entry is unlikely before 2027. Switzerland reviews transposition via ChemRRV/ORRChim.

How much microplastic is released in Switzerland?

According to FOEN estimates, around 14,000 tonnes of plastics enter the Swiss environment each year. Tyre wear, at roughly 8,100 tonnes, is by far the largest single source, followed by synthetic textiles, construction chemistry and packaging waste.

Should I throw away my non-stick pans?

Not necessarily. As long as the coating is intact and you cook at moderate heat, release is low per federal-authority assessments. Replace damaged pans (scratches, chips). Alternatives include stainless steel, cast iron and carbon steel.

Does a water filter help against PFAS?

Activated-carbon filters can reduce some PFAS. Effectiveness depends on the filter type, service life and PFAS chain length. Choose a certified product (NSF/ANSI 53/58 "PFOA/PFOS reduction") and follow the replacement schedule. With compliant tap water, a filter is not essential.
