Last PFAS check: · Source: Hub'eau
PFAS in drinking water
5.8× 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.
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 Grand-Fougeray, the 4 most closely watched PFAS (PFAS-4) add up to 2.89 ng/L (0.0029 µg/L) at the latest PFAS check on 26 March 2026. That's 5.8 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 2.89 ng/L (0.0029 µg/L), below the EU legal limit (100 ng/L). 2 checks since 20 August 2025: PFAS-4 from 0.72 ng/L to 2.89 ng/L.

Frequently asked questions
Is tap water in Grand-Fougeray safe to drink?
Yes. At the check on 22 July 2026, the tap water in Grand-Fougeray was within every limit tested. “Eau d'alimentation conforme aux limites réglementaires en vigueur, mais ne respectant pas la référence de qualité fixée pour le paramètre température en ce point d'échantillonage.”
How high are PFAS levels in Grand-Fougeray's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 2.89 ng/L. The EU limit is 100 ng/L, so this water is at 3 % of the limit. (below the EU limit)
Does the water in Grand-Fougeray also meet the strictest limits in Europe?
Yes. Even against Europe's strictest legal limit, Sweden's 4 ng/L in force since 2026, the measured value of 2.89 ng/L stays below.
Are PFAS levels rising in Grand-Fougeray's tap water?
Too few quantified checks to say (2 since 20 August 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.
How hard is the water in Grand-Fougeray?
The water hardness in Grand-Fougeray is 17.9 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 21 September 2026.
