PFAS in drinking water

None of the 4 most harmful PFAS detected

Amount found in the water < 4 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, 2.4 ng/L found in total
Our health benchmark 0.5 ng/L

The lab sees nothing below 4 ng/L, 8 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.

Sample taken in Rougemontier, on the same distribution network as Éturqueraye (ROUGEMONTIERS). The health authority samples one tap per network; a network carries the same treated water everywhere.

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 1 ng/L upward. None reached that limit, so their total is below 4 ng/L rather than zero.

None found. The lab sees nothing below 4 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Éturqueraye, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 23 April 2026. The total is below 4 ng/L, the sum of the detection limits and 8 times our 0.5 ng/L benchmark. Sum of 20 PFAS: 2.4 ng/L (0.0024 µg/L), below the EU legal limit (100 ng/L). Sampled in Rougemontier, on the same network. 2 checks since 9 April 2025: sum of 20 PFAS up to 2.4 ng/L, sometimes below the detection limit.

PFAS over time in Éturqueraye

2 PFAS checks since 9 April 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Éturqueraye.

“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 Éturqueraye safe to drink?

Yes. At the check on 23 April 2026, the tap water in Éturqueraye 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 Éturqueraye's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 2.4 ng/L. The EU limit is 100 ng/L, so this water is at 2 % of the limit. (below the EU limit)

Does the water in Éturqueraye also meet the strictest limits in Europe?

As far as this check can tell, yes. None of the four compounds was quantified, so their total is below 4 ng/L, the sum of the laboratory's detection limits, and under Sweden's legal limit of 4 ng/L in force since 2026.

Are PFAS levels rising in Éturqueraye'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 Éturqueraye?

The water hardness in Éturqueraye is 31.3 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?
