Switzerland and Austria occupy a distinctive position in European PFAS governance: both are non-EU states that have voluntarily aligned their chemical and environmental standards closely with EU REACH and the EU Drinking Water Directive, while also addressing contamination challenges specific to their alpine geography and industrial profiles. In 2025, both nations advanced their national PFAS frameworks through updated monitoring programs, enforcement actions at contaminated sites, and participation in the broader European scientific and regulatory dialogue.
Switzerland: Drinking Water Standards and PFAS Monitoring
Switzerland’s Federal Food Safety and Veterinary Office (FSVO) and the Federal Office for the Environment (FOEN) jointly administer drinking water quality oversight. Switzerland has adopted a drinking water guideline for PFAS aligned with the EU Drinking Water Directive—a parametric value of 100 ng/L for the sum of 20 named PFAS and 0.5 ng/L for any individual PFAS not on the named list—applied through the Federal Food Act (LMG) and associated ordinances. Swiss municipalities are required to monitor PFAS in drinking water sources and to report exceedances to cantonal authorities, who may order temporary use restrictions and installation of treatment systems.
Switzerland’s groundwater—the primary source for approximately 80% of the country’s drinking water—has been subject to PFAS surveys since 2015. The most significant contamination sources identified to date include military airfields where AFFF was historically used (Dübendorf, Meiringen, Payerne), industrial chemical manufacturing sites in the Rhine valley and around Basel, and contamination from ski resort operations where fluorinated ski wax has historically been applied. The Stockholm Convention’s listing of LC-PFCAs in May 2025—with bans entering force in December 2026—applies to Switzerland as a Convention signatory, and Swiss authorities are updating their national POPs Regulation accordingly.
Austria: Rhine-Danube Basin Contamination and Stricter Guidelines
Austria’s approach to PFAS regulation reflects both its EU membership and its specific position as a headwaters country for major European river systems including the Rhine (via the Vorarlberg region), the Danube, and the Inn. The Austrian Federal Environment Agency (Umweltbundesamt) has conducted systematic PFAS monitoring of groundwater and surface water across the country since 2019, with results showing contamination in several regions above EU Drinking Water Directive parametric values—particularly in Vorarlberg (near the Rheintal industrial corridor and former military sites) and Lower Austria (near the Danube floodplain).
Austria implemented the EU Drinking Water Directive 2020/2184 into national law through the Austrian Drinking Water Ordinance (Trinkwasserverordnung), which entered into force on January 12, 2023 for all EU member states. Austria has also been active in EU Working Group discussions on the practical implementation of PFAS monitoring requirements, contributing technical expertise from its experience with alpine groundwater systems where PFAS fate and transport behavior differs from lowland environments due to faster flow rates, lower temperatures, and the prevalence of karst aquifers that can rapidly transmit contamination across long distances.
Ski Wax PFAS: A Distinctly Alpine Issue
Switzerland, Austria, and other alpine nations face a contamination challenge with no direct parallel in most other PFAS regulatory contexts: the widespread historical use of fluorinated ski wax on recreational and competitive ski slopes. Fluorinated wax—applied in significant quantities at ski resorts throughout the Alps and Scandinavia—creates a diffuse PFAS load on snowpack that melts into streams, groundwater recharge zones, and alpine wetlands. Studies in Switzerland, Austria, and Norway have documented PFAS concentrations in mountain streams and alpine lakes attributable to ski wax application, with concentrations occasionally approaching EU guideline values in small headwater streams near major ski areas.
France’s January 2026 ban on PFAS-containing ski wax was the first national-level restriction on this application. Switzerland and Austria are monitoring the French implementation and are expected to implement similar restrictions, particularly in light of the EU REACH restriction proposal’s coverage of wax applications and the Stockholm Convention’s LC-PFCA listing, which covers several compounds used in ski wax formulations. Fluorine-free ski wax alternatives—already used extensively in competitive Nordic skiing following World Cup regulatory requirements—are commercially available and are being adopted by major ski resorts as consumer and regulatory pressure intensifies.
Water Treatment in Alpine Catchments
The specific hydrogeological characteristics of alpine water systems—fast groundwater travel times, relatively small catchment sizes, and high dependence on snowmelt recharge—mean that PFAS contamination in alpine drinking water sources can be highly variable and rapid-onset following contamination events. Swiss and Austrian municipalities near contaminated sites have invested in granular activated carbon treatment as a precautionary measure, even where current PFAS concentrations remain below guideline values, given the uncertainty about future contamination loads. OEM filter manufacturers with experience in high-flow, low-turbidity alpine raw water conditions—including properly specified GAC systems that account for lower temperatures reducing adsorption kinetics—are well positioned for the Swiss and Austrian municipal treatment market.
