PFAS in Gohory's tap water: 63 ng/L, 126x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
126× 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 Brou, on the same distribution network as Gohory (YEVRES MIGAUDIN). 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 Gohory, the 4 most closely watched PFAS (PFAS-4) add up to 63 ng/L (0.063 µg/L) at the latest PFAS check on 21 May 2026. That's 126 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 67 ng/L (0.067 µg/L), below the EU legal limit (100 ng/L). Sampled in Brou, on the same network. 9 checks since 27 March 2025: sum of 20 PFAS from 3 ng/L to 101 ng/L. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).
Details and sources
PFAS over time in Gohory
9 PFAS checks since 27 March 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Gohory.
“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 Gohory safe to drink?
Yes. At the check on 15 June 2026, the tap water in Gohory 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 Gohory's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 67 ng/L. The EU limit is 100 ng/L, so this water is at 67 % of the limit. (below the EU limit)
Does the water in Gohory also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 63 ng/L. That is 15.8 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 Gohory'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 Gohory?
The water hardness in Gohory is 23.3 °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 12 September 2026.
