PFAS in drinking water

No PFAS detected

Amount found in the water < 8 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, none found
Our health benchmark 0.5 ng/L

The lab sees nothing below 8 ng/L, 16 times our benchmark of 0.5 ng/L. Water above our benchmark would pass this check unnoticed.

0.5 ng/L is our benchmark, not an official limit. Same EFSA method as Sweden, Denmark and the Netherlands, but stricter. It's a yearly average, compared here with the latest check.

More about this result

The US also limits PFOA and PFOS to 4 ng/L each, per substance.

The lab detects each of the four substances from 2 ng/L upward. None reached that limit, so their total is below 8 ng/L rather than zero.

None found. The lab sees nothing below 8 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Raon-l'Étape, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 4 March 2026. The total is below 8 ng/L, the sum of the detection limits and 16 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,005 µg/L, below the EU legal limit (100 ng/L). 3 checks since 9 May 2025, sum of 20 PFAS always below the detection limit (5 ng/L).

PFAS over time in Raon-l'Étape

3 PFAS checks since 9 May 2025, from the published measurements. Samples come from 2 distribution networks. The trend refers to the network “RESEAU HAUTE-NEUVEVILLE”.

“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Frequently asked questions

Is tap water in Raon-l'Étape safe to drink?

Yes. At the check on 2 July 2026, the tap water in Raon-l'Étape was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”

How high are PFAS levels in Raon-l'Étape's drinking water?

At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 5 ng/L. The EU limit is 100 ng/L, so this water is under 5 % of the limit. (below the EU limit)

Does the water in Raon-l'Étape also meet the strictest limits in Europe?

The check cannot say. None of the four compounds was quantified, but the laboratory's detection limits add up to 8 ng/L, above Sweden's legal limit of 4 ng/L in force since 2026, so a value between the two would go unnoticed.

Are PFAS levels rising in Raon-l'Étape's tap water?

Calculated PFAS-4 values are listed in the table. The chart uses laboratory-published sum-of-20 results; there are too few laboratory-published PFAS-4 sums for the existing trend calculation.

How hard is the water in Raon-l'Étape?

The water hardness in Raon-l'Étape is 10.9 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
