PFAS in the tap water of Saint-Chamant (Cantal): under 13 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
No PFAS detected
The lab sees nothing below 13 ng/L, 26 times our benchmark of 0.5 ng/L. Water above our benchmark would pass this check unnoticed.
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 Besse, on the same distribution network as Saint-Chamant (DE ST PROJET BESSE ST MARTIN CANTALES). 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.
The lab detects each of the four substances from 1.5 to 5 ng/L upward. None reached that limit, so their total is below 13 ng/L rather than zero.

In Saint-Chamant, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 18 June 2026. The total is below 13 ng/L, the sum of the detection limits and 26 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,0895 µg/L, below the EU legal limit (100 ng/L). Sampled in Besse, on the same network. 3 checks since 9 July 2025, PFAS-4 always below the detection limit (13 ng/L). Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

PFAS over time in Saint-Chamant
3 PFAS checks since 9 July 2025, values as published. Samples from 2 communes on the same network: it's the same water, so each one applies to Saint-Chamant.
| Date | PFAS-4 | Sum of 20 PFAS | Sampled at |
|---|---|---|---|
| < 13 ng/L | < 89.5 ng/L | Besse | |
| < 13 ng/L | < 89.5 ng/L | Saint-Projet-de-Salers | |
| < 4 ng/L | < 71 ng/L | Saint-Projet-de-Salers |
“<” means not detected, the figure being the detection limit. “–” means not published. Labs have only reported the PFAS-4 sum (SANDRE code 9268) since autumn 2025. How to read a PFAS result

Frequently asked questions
Is tap water in Saint-Chamant safe to drink?
Yes. At the check on 18 June 2026, the tap water in Saint-Chamant was within every limit tested. Outside a reference value: Electrical conductivity 56 µS/cm on 18 June 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Résultats d'analyses conformes à la norme. Toutefois, présence excessive de germes à 22 et 36°C : eau de qualité sanitaire non satisfaisante.”
How high are PFAS levels in Saint-Chamant's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 89.5 ng/L. The EU limit is 100 ng/L, so this water is under 89 % of the limit. (below the EU limit)
Does the water in Saint-Chamant also meet the strictest limits in Europe?
The check cannot say. None of the four compounds was quantified, but the laboratory's detection limits add up to 13 ng/L, above Sweden's legal limit of 4 ng/L in force since 2026, so a value between the two would go unnoticed.
Are PFAS levels rising in Saint-Chamant's tap water?
No. Since 9 July 2025, 3 checks have been published and the PFAS-4 sum stayed below the laboratory's detection limit (13 ng/L) every time.
How hard is the water in Saint-Chamant?
The water hardness in Saint-Chamant is 2 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
