PFAS in drinking water

5.8× above our health benchmark

Amount found in the water 2.89 ng/L 0.0029 µg/L · the 4 most harmful PFAS (PFAS-4)
Our health benchmark 0.5 ng/L

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 Grand-Fougeray, on the same distribution network as La Dominelais (PAYS BAIN_BOUTRATAIS_GRAND FOUGERAY). 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).

In La Dominelais, the 4 most closely watched PFAS (PFAS-4) add up to 2.89 ng/L (0.0029 µg/L) at the latest PFAS check on 26 March 2026. That's 5.8 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 2.89 ng/L (0.0029 µg/L), below the EU legal limit (100 ng/L). Sampled in Grand-Fougeray, on the same network. 2 checks since 20 August 2025: PFAS-4 from 0.72 ng/L to 2.89 ng/L. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions

Is tap water in La Dominelais safe to drink?

Yes. At the check on 19 May 2026, the tap water in La Dominelais 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 La Dominelais's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 2.89 ng/L. The EU limit is 100 ng/L, so this water is at 3 % of the limit. (below the EU limit)

Does the water in La Dominelais 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 2.89 ng/L stays below.

Are PFAS levels rising in La Dominelais's tap water?

Too few quantified checks to say (2 since 20 August 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.

How hard is the water in La Dominelais?

The water hardness in La Dominelais is 18.1 °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 12 September 2026.

Same water network

Same distribution network as La Dominelais, so in principle the same water.
