PFAS in drinking water
13.4× above our health benchmark
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 Petit-Caux, on the same distribution network as Bailly-en-Rivière (EU ENVERMEU). 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.
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 Bailly-en-Rivière, the 4 most closely watched PFAS (PFAS-4) add up to 6.7 ng/L (0.0067 µg/L) at the latest PFAS check on 13 April 2026. That's 13.4 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 22.2 ng/L (0.0222 µg/L), below the EU legal limit (100 ng/L). Sampled in Petit-Caux, on the same network. 4 checks since 28 January 2025: sum of 20 PFAS up to 22.2 ng/L, sometimes below the detection limit.

Details and sources
PFAS over time in Bailly-en-Rivière
4 PFAS checks since 28 January 2025, from the published measurements. Samples from 3 communes on the same network: it's the same water, so each one applies to Bailly-en-Rivière. Samples come from 2 distribution networks. The trend refers to the network “EU ENVERMEU”.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.
| Date | PFAS-4 | Sum of 20 PFAS | Sampled at | Network |
|---|---|---|---|---|
| 6.7 ng/L – < 8.7 ng/L · calculated | 22.2 ng/L | Petit-Caux | EU ENVERMEU | |
| 3 ng/L – < 5 ng/L · calculated | 5 ng/L | Envermeu | EU ENVERMEU | |
| < 4 ng/L · calculated | < detection limit | Villy-sur-Yères | EU FRESNOY FOLNY | |
| 8 ng/L – < 10 ng/L · calculated | < detection limit | Envermeu | EU ENVERMEU |
Calculated values: “<” is an upper bound from published thresholds, “≥” a lower bound, “–” means no published sum or complete measurement. How to read a PFAS result

Frequently asked questions
Is tap water in Bailly-en-Rivière safe to drink?
Yes. At the check on 13 April 2026, the tap water in Bailly-en-Rivière 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 Bailly-en-Rivière's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 22.2 ng/L. The EU limit is 100 ng/L, so this water is at 22 % of the limit. (below the EU limit)
Does the water in Bailly-en-Rivière also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 6.7 ng/L. That is 1.68 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 Bailly-en-Rivière'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 Bailly-en-Rivière?
The water hardness in Bailly-en-Rivière is 26 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
