PFAS in drinking water

2.4× above our health benchmark

Amount found in the water 1.2 ng/L 0.0012 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.

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 Huelgoat, the 4 most closely watched PFAS (PFAS-4) add up to 1.2 ng/L (0.0012 µg/L) at the latest PFAS check on 24 September 2025. That's 2.4 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 30.3 ng/L (0.0303 µg/L), below the EU legal limit (100 ng/L).

Frequently asked questions

Is tap water in Huelgoat safe to drink?

Yes. At the check on 7 July 2026, the tap water in Huelgoat was within every limit tested. Outside a reference value: Electrical conductivity 154 µS/cm on 7 July 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Eau prélevée conforme aux limites de qualité. A noter une conductivité inférieure à la valeur de référence minimale de 200µS/cm. Eau agressive. Une optimisation du traitement de neutralisation-minéralisation à l'unité de production est nécessaire.”

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

The total of 20 PFAS ("forever chemicals") was last measured at 30.3 ng/L. The EU limit is 100 ng/L, so this water is at 30 % of the limit. (below the EU limit)

Does the water in Huelgoat 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 1.2 ng/L stays below.

How hard is the water in Huelgoat?

The water hardness in Huelgoat is 3.2 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?
