PFAS in Chaniers'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 La Chapelle-des-Pots, on the same distribution network as Chaniers (R. NORD DE CHANIERS). 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.

None found. The lab sees nothing below 14 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Chaniers, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 22 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). Sampled in La Chapelle-des-Pots, on the same network. 5 checks since 16 May 2025, sum of 20 PFAS always below the detection limit.

Details and sources
PFAS over time in Chaniers
5 PFAS checks since 16 May 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Chaniers. Samples come from 2 distribution networks. The trend refers to the network “R. NORD DE CHANIERS”.
“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 | Network |
|---|---|---|---|---|
| < 14 ng/L · calculated | < detection limit | La Chapelle-des-Pots | R. NORD DE CHANIERS | |
| < 4 ng/L · calculated | < detection limit | Chérac | R. SUD DE CHANIERS | |
| < 4 ng/L · calculated | < detection limit | La Chapelle-des-Pots | R. NORD DE CHANIERS | |
| < 4 ng/L · calculated | < detection limit | Chérac | R. SUD DE CHANIERS | |
| < 4 ng/L · calculated | < detection limit | La Chapelle-des-Pots | R. NORD DE CHANIERS |
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 Chaniers safe to drink?
Yes. At the check on 23 July 2026, the tap water in Chaniers was within every limit tested. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité.”
How high are PFAS levels in Chaniers'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 Chaniers 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 Chaniers'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 Chaniers?
The water hardness in Chaniers is 33.4 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
