PFAS in Pouillac's tap water: under 14 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 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.
Sample taken in Chevanceaux, on the same distribution network as Pouillac (R. DE MONTLIEU-MONTGUYON). 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 2 to 5 ng/L upward. None reached that limit, so their total is below 14 ng/L rather than zero.

In Pouillac, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 11 June 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). Sampled in Chevanceaux, on the same network. 3 checks since 31 July 2025, sum of 20 PFAS always below the detection limit.

Details and sources
PFAS over time in Pouillac
3 PFAS checks since 31 July 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Pouillac.
“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 |
|---|---|---|---|
| < 14 ng/L · calculated | < detection limit | Chevanceaux | |
| < 4 ng/L · calculated | < detection limit | Saint-Palais-de-Négrignac | |
| < 4 ng/L · calculated | < detection limit | Chevanceaux |
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 Pouillac safe to drink?
Yes. At the check on 11 June 2026, the tap water in Pouillac was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”
How high are PFAS levels in Pouillac'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 Pouillac 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 Pouillac'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 Pouillac?
No hardness value is available for Pouillac in this source.
