PFAS in drinking water

No PFAS detected

Amount found in the water < 2.5 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, none found
Our health benchmark 0.5 ng/L

The lab sees nothing below 2.5 ng/L, 5 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.

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 0.5 to 1 ng/L upward. None reached that limit, so their total is below 2.5 ng/L rather than zero.

None found. The lab sees nothing below 2.5 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Athée, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 11 May 2026. The total is below 2.5 ng/L, the sum of the detection limits and 5 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <SEUIL µg/L, below the EU legal limit (100 ng/L). 3 checks since 23 September 2025, PFAS-4 always below the detection limit.

PFAS over time in Athée

6 PFAS checks since 5 November 2024, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Athée.

“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 Athée safe to drink?

Yes. At the check on 11 May 2026, the tap water in Athée 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 Athée's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at –. The EU limit is 100 ng/L, so this water is at – of the limit. (below the EU limit)

Does the water in Athée also meet the strictest limits in Europe?

As far as this check can tell, yes. None of the four compounds was quantified, so their total is below 2.5 ng/L, the sum of the laboratory's detection limits, and under Sweden's legal limit of 4 ng/L in force since 2026.

Are PFAS levels rising in Athée's tap water?

No. Since 5 November 2024, 3 checks have been published and the PFAS-4 sum stayed below the laboratory's detection limit every time. These history statistics use laboratory-published sums only.

How hard is the water in Athée?

The water hardness in Athée is 23.3 °f (medium). 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.
