PFAS in Gévezé's tap water: 1 ng/L, 2x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
2× 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 Gévezé, the 4 most closely watched PFAS (PFAS-4) add up to 1 ng/L (0.001 µg/L) at the latest PFAS check on 23 July 2026. That's 2 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 1 ng/L (0.001 µg/L), below the EU legal limit (100 ng/L). 9 checks since 24 April 2025: PFAS-4 up to 1 ng/L, sometimes below the detection limit, averaging at least 0.33 ng/L over 12 months (non-detects as 0). No clear trend. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions
Is tap water in Gévezé safe to drink?
Yes. At the check on 23 July 2026, the tap water in Gévezé was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés. Cependant, il convient de signaler la présence de traces de pesticides et la mise en évidence de chlorates. La réglementation fixe une limite de qualité à 700 µg/l pour ce paramètre, lorsqu'une méthode de désinfection des eaux destinées à la consommation humaine qui en génére est utilisée. Au delà de cette valeur, il est recommandé de ne pas consommer cette eau, une restriction d'usage est nécessaire. La valeur la plus faible possible de ce paramètre doit être visée sans pour autant compromettre la désinfection. Compte tenu de la teneur mesurée en chlorates, un suivi renforcé sera mis en place sur ce paramètre.”
How high are PFAS levels in Gévezé's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 1 ng/L. The EU limit is 100 ng/L, so this water is at 1 % of the limit. (below the EU limit)
Does the water in Gévezé 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 1 ng/L stays below.
Are PFAS levels rising in Gévezé's tap water?
No clear trend. Since 24 April 2025, 9 checks have been published; on the main network the PFAS-4 sum ranged between 0.44 ng/L and 1 ng/L (5 quantified values), at times below the detection limit. pfasnearme only reports a trend from a change of at least 25 % and 1 ng/L.
How hard is the water in Gévezé?
The water hardness in Gévezé is 19.2 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
