PFAS in Lapenne's tap water: under 24 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
No PFAS detected
The lab sees nothing below 24 ng/L, 48 times our benchmark of 0.5 ng/L. Water above our benchmark would pass this check unnoticed.
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 Saint-Amadou, on the same distribution network as Lapenne (ST FELIX DE TOURNEGAT - LAPENNE - ECARTS GAUDIES). 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.
The lab detects each of the four substances from 2 to 10 ng/L upward. None reached that limit, so their total is below 24 ng/L rather than zero.

None found. The lab sees nothing below 24 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Lapenne, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 10 February 2026. The total is below 24 ng/L, the sum of the detection limits and 48 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,002 µg/L, below the EU legal limit (100 ng/L).

Frequently asked questions
Is tap water in Lapenne safe to drink?
Yes. At the check on 10 February 2026, the tap water in Lapenne 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 Lapenne's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 2 ng/L. The EU limit is 100 ng/L, so this water is under 2 % of the limit. (below the EU limit)
Does the water in Lapenne also meet the strictest limits in Europe?
The check cannot say. None of the four compounds was quantified, but the laboratory's detection limits add up to 24 ng/L, above Sweden's legal limit of 4 ng/L in force since 2026, so a value between the two would go unnoticed.
How hard is the water in Lapenne?
No hardness value is available for Lapenne in this source.
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.
