74× above our health benchmark

Amount found in the water 37 ng/L 0.037 µg/L · the 4 most harmful PFAS (PFAS-4)
Our health benchmark 0.5 ng/L

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.

Substances below the detection limit count as 0, so the real total may be higher.

One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

In Briquenay, the 4 most closely watched PFAS (PFAS-4) add up to 37 ng/L (0.037 µg/L) at the latest PFAS check on 17 December 2025. That's 74 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 60 ng/L (0.06 µg/L), below the EU legal limit (100 ng/L). 7 checks since 23 May 2025: sum of 20 PFAS from 56 ng/L to 68 ng/L.

PFAS over time in Briquenay

7 PFAS checks since 23 May 2025, from the published measurements. Samples from 6 communes on the same network: it's the same water, so each one applies to Briquenay.

“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 Briquenay safe to drink?

At the latest check, the water was over at least one limit. “Eau destinée à la consommation humaine conforme pour l'ensemble des paramètres analysés. Toutefois, la référence de qualité(norme non impérative) relative à la numération des bactéries coliformes n'est pas satisfaite. Une vérification des installations peut s'avérer nécessaire, notamment le traitement de désinfection s'il existe.”

How high are PFAS levels in Briquenay's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 60 ng/L. The EU limit is 100 ng/L, so this water is at 60 % of the limit. (below the EU limit)

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

No. The four most harmful PFAS add up to 37 ng/L. That is 9.3 times Sweden's legal limit of 4 ng/L, in force since 2026. Germany will set a similar one in 2028. The water still passes the current EU legal limit (100 ng/L for the total of 20 PFAS).

Are PFAS levels rising in Briquenay'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 Briquenay?

No hardness value is available for Briquenay in this source.
