PFAS in Archignat's tap water: 25 ng/L, 50x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
50× 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 Domérat, on the same distribution network as Archignat (RESEAU PRAT - RIVE GAUCHE CHER). 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.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

In Archignat, the 4 most closely watched PFAS (PFAS-4) add up to 25 ng/L (0.025 µg/L) at the latest PFAS check on 3 February 2026. That's 50 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 Domérat, on the same network. 2 checks since 2 September 2025: PFAS-4 up to 25 ng/L, sometimes below the detection limit.

PFAS over time in Archignat
5 PFAS checks since 2 April 2025, from the published measurements. Samples from 3 communes on the same network: it's the same water, so each one applies to Archignat.
“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 |
|---|---|---|---|
| 25 ng/L | 60 ng/L | Domérat | |
| < 4 ng/L | 4 ng/L | Quinssaines | |
| < 4 ng/L · calculated | 2 ng/L | Sainte-Thérence | |
| < 4 ng/L · calculated | 2 ng/L | Quinssaines | |
| < 4 ng/L · calculated | < 100 ng/L | Sainte-Thérence |
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 Archignat safe to drink?
Yes. At the check on 3 February 2026, the tap water in Archignat was within every limit tested. “Eau conforme aux limites et aux références de qualité pour ce qui concerne les paramètres mesurés.”
How high are PFAS levels in Archignat'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 Archignat also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 25 ng/L. That is 6.3 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 Archignat's tap water?
Too few quantified checks to say (1 since 2 April 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values. These history statistics use laboratory-published sums only.
How hard is the water in Archignat?
The water hardness in Archignat is 15.2 °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.
