No PFAS detected

Amount found in the water < 14 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, none found
Our health benchmark 0.5 ng/L

The lab sees nothing below 14 ng/L, 28 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 2 to 5 ng/L upward. None reached that limit, so their total is below 14 ng/L rather than zero.

In Vouillé, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 8 July 2026. The total is below 14 ng/L, the sum of the detection limits and 28 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <SEUIL µg/L, below the EU legal limit (100 ng/L). 5 checks since 16 May 2025: sum of 20 PFAS up to 2.9 ng/L, sometimes below the detection limit.

PFAS over time in Vouillé

5 PFAS checks since 16 May 2025, from the published measurements. Samples from 3 communes on the same network: it's the same water, so each one applies to Vouillé.

“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 Vouillé safe to drink?

At the latest check, the water was over at least one limit. “Eau d'alimentation non-conforme aux exigences de qualité.La concentrat ion en chlorates dépasse la limite de qualité. Il est demandé à l'expl oitant de prendre les mesures correctives adaptées. Un suivi renforcé est mis en place.”

How high are PFAS levels in Vouillé's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at –. The EU limit is 100 ng/L, so this water is at – of the limit. (below the EU limit)

Does the water in Vouillé 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 14 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 Vouillé'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 Vouillé?

The water hardness in Vouillé is 11.7 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?
