PFAS in Autruche's tap water: 37 ng/L, 74x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
74× 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 Briquenay, on the same distribution network as Autruche (S16 BUZANCY). 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 Autruche, the 4 most closely watched PFAS (PFAS-4) add up to 37 ng/L (0.037 µg/L) at the latest PFAS check on 17 December 2025. That's 74 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 60 ng/L (0.06 µg/L), below the EU legal limit (100 ng/L). Sampled in Briquenay, on the same network. 7 checks since 23 May 2025: sum of 20 PFAS from 56 ng/L to 68 ng/L. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

PFAS over time in Autruche
7 PFAS checks since 23 May 2025, from the published measurements. Samples from 6 communes on the same network: it's the same water, so each one applies to Autruche.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

What the latest check found
At the latest check, the water was within every limit tested.
Values to watch
These results are close to their legal limit, or over it.
One routine sample was outside a limit: Lead 57 µg/L on 20 November 2020 (limit ≤ 10 µg/L). This is a single result, not an official verdict on the supply.
| What was tested | Value | Limit | Status |
|---|---|---|---|
| Nitrate | 36.1 mg/L | ≤ 50 mg/L | within the limit |
| Lead | 57 µg/L | ≤ 10 µg/L | over the limit |

Frequently asked questions
Is tap water in Autruche safe to drink?
Yes. At the check on 17 April 2026, the tap water in Autruche was within every limit tested. One routine sample was outside a limit: Lead 57 µg/L on 20 November 2020 (limit ≤ 10 µg/L). This is a single result, not an official verdict on the supply. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité. La référence de qualité (norme non impérative) relative à la présence de bactéries anaérobies sulfito-réductrices y compris les spores n'est pas satisfaite. Une vérification des installations peut s'avérer nécessaire.”
How high are PFAS levels in Autruche's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 60 ng/L. The EU limit is 100 ng/L, so this water is at 60 % of the limit. (below the EU limit)
Does the water in Autruche also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 37 ng/L. That is 9.3 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 Autruche'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 Autruche?
The water hardness in Autruche is 26.6 °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.
