PFAS in Le Crestet'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
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 Le Crestet, the 4 most closely watched PFAS (PFAS-4) add up to 2 ng/L (0.002 µg/L) at the latest PFAS check on 12 June 2026. 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: 16 ng/L (0.016 µg/L), below the EU legal limit (100 ng/L). 2 checks since 5 June 2026: PFAS-4 up to 2 ng/L, sometimes below the detection limit.

PFAS over time in Le Crestet
4 PFAS checks since 3 April 2025, from the published measurements. Samples come from 3 distribution networks. The trend refers to the network “LE CRESTET UDI GROUBON MONTEIL”.
“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 | Network |
|---|---|---|---|
| 2 ng/L | 16 ng/L | LE CRESTET UDI LES ROCHETTES | |
| < 4 ng/L | < 29 ng/L | LE CRESTET UDI GROUBON MONTEIL | |

Frequently asked questions
Is tap water in Le Crestet safe to drink?
All the values shown here (15 June 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”
How high are PFAS levels in Le Crestet's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 16 ng/L. The EU limit is 100 ng/L, so this water is at 16 % of the limit. (below the EU limit)
Does the water in Le Crestet 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.
Are PFAS levels rising in Le Crestet's tap water?
Too few quantified checks to say (0 since 3 April 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values. These history statistics use laboratory-published sums only.
How hard is the water in Le Crestet?
The water hardness in Le Crestet is 8.6 °f (soft). 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 28 September 2026.
