PFAS in L'Écouvotte's tap water: 3 ng/L, 6x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
6× 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.
Sample taken in Avilley, on the same distribution network as L'Écouvotte (RESEAU PUITS FOURBANNE). 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 L'Écouvotte, the 4 most closely watched PFAS (PFAS-4) add up to 3 ng/L (0.003 µg/L) at the latest PFAS check on 25 February 2026. That's 6 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 3 ng/L (0.003 µg/L), below the EU legal limit (100 ng/L). Sampled in Avilley, on the same network. 2 checks since 29 September 2025: PFAS-4 from 3 ng/L to 4 ng/L. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).
Details and sources
PFAS over time in L'Écouvotte
4 PFAS checks since 9 December 2024, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to L'Écouvotte.
“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 |
|---|---|---|---|
| 3 ng/L | 3 ng/L | Avilley | |
| 4 ng/L | 4 ng/L | Fourbanne | |
| < 4 ng/L · calculated | < 100 ng/L | Fourbanne | |
| 2 ng/L – < 4 ng/L · calculated | 2 ng/L | Fourbanne |
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 L'Écouvotte safe to drink?
Yes. At the check on 15 June 2026, the tap water in L'Écouvotte was within every limit tested. “EAU CONFORME (code de la santé publique) L'eau prélevée respecte les exigences réglementaires des eaux destinées à l'alimentation humaine pour les paramètres analysés. Cependant la présence de chlore résiduel en excès entraîne des désagréments pour les usagers et peut conduire à la production de substances organochlorées.”
How high are PFAS levels in L'Écouvotte's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 3 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 L'Écouvotte 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 3 ng/L stays below.
Are PFAS levels rising in L'Écouvotte's tap water?
Too few quantified checks to say (2 since 9 December 2024). 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 L'Écouvotte?
The water hardness in L'Écouvotte is 31.5 °f (hard). 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.
