PFAS in Lignairolles's tap water: none of the four main PFAS detected

PFAS in drinking water

not precise enough to compare

Amount found in the water PFAS-4 not detected the 4 most harmful PFAS (PFAS-4)
Our health benchmark 0.5 ng/L

Some of the four PFAS were too small for the lab to measure. The check cannot say whether this water is above or below our benchmark of 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 Tréziers, on the same distribution network as Lignairolles (LIGNAIROLLES). The health authority samples one tap per network; a network carries the same treated water everywhere.

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.

In Lignairolles, none of the 4 most closely watched PFAS (PFAS-4) was found in a measurable amount at the latest PFAS check on 1 July 2025. That's below the detection limit, so there's no verdict against our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,002 µg/L, below the EU legal limit (100 ng/L). Sampled in Tréziers, on the same network.

Frequently asked questions

Is tap water in Lignairolles safe to drink?

Yes. At the check on 17 June 2026, the tap water in Lignairolles 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 Lignairolles'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 Lignairolles also meet the strictest limits in Europe?

The check cannot say. None of the four compounds was quantified, and the source does not publish detection limits fine enough to compare their total with Sweden's legal limit of 4 ng/L in force since 2026.

How hard is the water in Lignairolles?

The water hardness in Lignairolles is 21.5 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
