PFAS in Le Champ-de-la-Pierre's tap water: 11.2 ng/L, 22.4x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
22.4× 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 Saint-Brice-sous-Rânes, on the same distribution network as Le Champ-de-la-Pierre (RANES ECOUCHE). 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 Le Champ-de-la-Pierre, the 4 most closely watched PFAS (PFAS-4) add up to 11.2 ng/L (0.0112 µg/L) at the latest PFAS check on 30 June 2026. That's 22.4 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 56.1 ng/L (0.0561 µg/L), below the EU legal limit (100 ng/L). Sampled in Saint-Brice-sous-Rânes, on the same network. 2 checks since 10 June 2025: sum of 20 PFAS from 2.1 ng/L to 56.1 ng/L.

PFAS over time in Le Champ-de-la-Pierre
2 PFAS checks since 10 June 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Le Champ-de-la-Pierre.
“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 |
|---|---|---|---|
| 11.2 ng/L – < 13.2 ng/L · calculated | 56.1 ng/L | Saint-Brice-sous-Rânes | |
| < 4 ng/L · calculated | 2.1 ng/L | Écouché-les-Vallées |
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 Le Champ-de-la-Pierre safe to drink?
Yes. At the check on 30 June 2026, the tap water in Le Champ-de-la-Pierre 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 Le Champ-de-la-Pierre's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 56.1 ng/L. The EU limit is 100 ng/L, so this water is at 56 % of the limit. (below the EU limit)
Does the water in Le Champ-de-la-Pierre also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 11.2 ng/L. That is 2.8 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 Le Champ-de-la-Pierre'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 Le Champ-de-la-Pierre?
The water hardness in Le Champ-de-la-Pierre is 34.1 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
