PFAS in Bourret's tap water: 2 ng/L, 4x our 0.5 ng/L benchmark

Last PFAS check: · Source: Hub'eau

PFAS in drinking water

4× above our health benchmark

Amount found in the water 2 ng/L 0.002 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 Mas-Grenier, on the same distribution network as Bourret (MAS GRENIER (UDI)). 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).

More PFAS than in 85% of the cities we track

In Bourret, the 4 most closely watched PFAS (PFAS-4) add up to 2 ng/L (0.002 µg/L) at the latest PFAS check on 5 August 2025. That's 4 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: <0,044 µg/L, below the EU legal limit (100 ng/L). Sampled in Mas-Grenier, on the same network.

Frequently asked questions

Is tap water in Bourret safe to drink?

Yes. At the check on 16 March 2026, the tap water in Bourret 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 Bourret's drinking water?

At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 44 ng/L. The EU limit is 100 ng/L, so this water is under 44 % of the limit. (below the EU limit)

Does the water in Bourret 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 ng/L stays below.

How hard is the water in Bourret?

The water hardness in Bourret is 24.7 °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.
