PFAS in drinking water
16.4× 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 Saint-Lézer, the 4 most closely watched PFAS (PFAS-4) add up to 8.2 ng/L (0.0082 µg/L) at the latest PFAS check on 11 May 2026. That's 16.4 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 44 ng/L (0.044 µg/L), below the EU legal limit (100 ng/L). 2 checks since 14 January 2026: PFAS-4 from 8 ng/L to 14 ng/L.

PFAS over time in Saint-Lézer
3 PFAS checks since 13 October 2025, from the published measurements. Samples from 3 communes on the same network: it's the same water, so each one applies to Saint-Lézer.
“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 | Sampled at |
|---|---|---|---|
| 8 ng/L | 44 ng/L | Saint-Lézer | |
| 14 ng/L | 42 ng/L | Andrest | |
| 4 ng/L – < 19 ng/L · calculated | 36 ng/L | Oursbelille |
Calculated values: “<” is an upper bound from published thresholds, “≥” a lower bound, “–” means no published sum or complete measurement. How to read a PFAS result

Frequently asked questions
Is tap water in Saint-Lézer safe to drink?
Yes. At the check on 18 May 2026, the tap water in Saint-Lézer 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 Saint-Lézer's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 44 ng/L. The EU limit is 100 ng/L, so this water is at 44 % of the limit. (below the EU limit)
Does the water in Saint-Lézer also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 8.2 ng/L. That is 2.1 times Sweden's legal limit of 4 ng/L, in force since 2026. Germany will set a similar one in 2028. The water still passes the current EU legal limit (100 ng/L for the total of 20 PFAS).
Are PFAS levels rising in Saint-Lézer's tap water?
Too few quantified checks to say (2 since 13 October 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 Saint-Lézer?
The water hardness in Saint-Lézer is 13.7 °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 12 September 2026.
