PFAS in drinking water

16.4× above our health benchmark

Amount found in the water 8.2 ng/L 0.0082 µg/L · the 4 most harmful PFAS (PFAS-4)
Our health benchmark 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 Saint-Lézer, on the same distribution network as Aurensan (NORD DE TARBES). 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 Aurensan, 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). Sampled in Saint-Lézer, on the same network. 2 checks since 14 January 2026: PFAS-4 from 8 ng/L to 14 ng/L. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

PFAS over time in Aurensan

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 Aurensan.

“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Frequently asked questions

Is tap water in Aurensan safe to drink?

Yes. At the check on 11 May 2026, the tap water in Aurensan 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 Aurensan'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 Aurensan 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 Aurensan'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 Aurensan?

The water hardness in Aurensan is 13.5 °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.

Same water network
