PFAS in Dourdain's tap water: between 0.47 and 3.47 ng/L
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
PFAS-4 found at a low level
0.47 ng/L of PFAS-4 was found. The other substances were below the lab's detection limit, so the true total sits between 0.47 ng/L and 3.47 ng/L. Our benchmark of 0.5 ng/L falls inside that range, so the check cannot settle it.
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 Bouëxière, on the same distribution network as Dourdain (LIFFRE CORMIER_BILLERIE/GRANGE_LIFFRE). 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.
Substances below the detection limit count as 0, so the real total may be higher.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

Some PFAS found. The test cannot say if the water is above or below our 0.5 ng/L benchmark.

In Dourdain, the 4 most closely watched PFAS (PFAS-4) add up to between 0.47 ng/L and 3.47 ng/L at the latest PFAS check on 8 April 2026, because some were below the detection limit. Our 0.5 ng/L benchmark falls inside that range, so there's no verdict. Sum of 20 PFAS: 2.15 ng/L (0.0022 µg/L), below the EU legal limit (100 ng/L). Sampled in La Bouëxière, on the same network. 2 checks since 26 February 2026: PFAS-4 up to 0.47 ng/L, sometimes below the detection limit.

PFAS over time in Dourdain
2 PFAS checks since 26 February 2026, values as published. Samples from 2 communes on the same network: it's the same water, so each one applies to Dourdain.
| Date | PFAS-4 | Sum of 20 PFAS | Sampled at |
|---|---|---|---|
| 0.47 ng/L | 2.15 ng/L | La Bouëxière | |
| < detection limit | 1.2 ng/L | Dourdain |
“<” 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 Dourdain safe to drink?
Yes. At the check on 8 July 2026, the tap water in Dourdain 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 Dourdain's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 2.15 ng/L. The EU limit is 100 ng/L, so this water is at 2 % of the limit. (below the EU limit)
Does the water in Dourdain also meet the strictest limits in Europe?
Yes. Even against Europe's strictest legal limit, Sweden's 4 ng/L in force since 2026, the measured value of 0.47 ng/L stays below.
Are PFAS levels rising in Dourdain's tap water?
Too few quantified checks to say (1 since 26 February 2026). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.
How hard is the water in Dourdain?
The water hardness in Dourdain is 18.2 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 21 September 2026.
