PFAS in Saint-Étienne-du-Valdonnez's tap water: under 6 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 6 ng/L, 12 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.
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 ng/L upward. None reached that limit, so their total is below 6 ng/L rather than zero.

In Saint-Étienne-du-Valdonnez, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 27 April 2026. The total is below 6 ng/L, the sum of the detection limits and 12 times our 0.5 ng/L benchmark. Sum of 20 PFAS: not detected, below the EU legal limit (100 ng/L). 2 checks since 26 January 2026, PFAS-4 always below the detection limit (6 ng/L).

Frequently asked questions
Is tap water in Saint-Étienne-du-Valdonnez safe to drink?
Yes. At the check on 29 June 2026, the tap water in Saint-Étienne-du-Valdonnez was within every limit tested. Outside a reference value: Electrical conductivity 44 µS/cm on 29 June 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité.”
How high are PFAS levels in Saint-Étienne-du-Valdonnez's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was reported as not detected; the laboratory did not state its reporting limit. The EU limit is 100 ng/L. (below the EU limit)
Does the water in Saint-Étienne-du-Valdonnez 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 6 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-Étienne-du-Valdonnez's tap water?
Too few quantified checks to say (0 since 26 January 2026). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.
How hard is the water in Saint-Étienne-du-Valdonnez?
The water hardness in Saint-Étienne-du-Valdonnez is 1.2 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
