PFAS: the new European standard comes into force in Luxembourg

Since January 2026, tap water must comply with a combined limit for 20 PFAS. What this changes.

01

An unprecedented standard at European level

Directive 2020/2184 introduces, for the first time, a regulatory limit on PFAS in tap water: 100 ng/L combined for 20 compounds. This standard came into application in January 2026 in all EU Member States, including Luxembourg.

02

Consequences for water suppliers

The Water Management Administration and the water boards must now include PFAS in their regular monitoring. Investments in activated-carbon and reverse-osmosis filtration technologies are expected at the level of the treatment plants.

03

And for you, at home?

If you live near areas where firefighting foams were historically used (airports, military barracks) or near certain industrial facilities, prudence suggests fitting an under-sink reverse-osmosis unit today. It is also the simplest way to get ahead of any future regulatory changes.
