PFAS in Sixt-sur-Aff's tap water: 3.06 ng/L, 6.1x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
6.1× 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 Bains-sur-Oust, on the same distribution network as Sixt-sur-Aff (REDON_CHAMP JAMET_BAIN SUR OUST). 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 Sixt-sur-Aff, the 4 most closely watched PFAS (PFAS-4) add up to 3.06 ng/L (0.0031 µg/L) at the latest PFAS check on 19 May 2026. That's 6.1 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 7.41 ng/L (0.0074 µg/L), below the EU legal limit (100 ng/L). Sampled in Bains-sur-Oust, on the same network. 4 checks since 21 July 2025: PFAS-4 from 1.9 ng/L to 3.06 ng/L, averaging 2.33 ng/L over 12 months. Rising on the main network.

Details and sources
PFAS over time in Sixt-sur-Aff
5 PFAS checks since 27 February 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Sixt-sur-Aff. Samples come from 3 distribution networks. The trend refers to the network “REDON_CHAMP JAMET_BAIN SUR OUST”.
“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 Sixt-sur-Aff safe to drink?
Yes. At the check on 7 July 2026, the tap water in Sixt-sur-Aff was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés. Il convient cependant de noter l'absence de chlore résiduel sur ce secteur de distribution. D'une façon générale, la présence d'un résiduel de chlore est nécessaire pour se prémunir de la prolifération bactérienne dans les réseaux (objectif souhaitable : 0,1 mg/L de chlore libre). L'exploitant a été informé de cette situation dès connaissance de celle-ci par mon service, pour vérifications et actions correctives d'usage.”
How high are PFAS levels in Sixt-sur-Aff's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 7.41 ng/L. The EU limit is 100 ng/L, so this water is at 7 % of the limit. (below the EU limit)
Does the water in Sixt-sur-Aff 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 3.06 ng/L stays below.
Are PFAS levels rising in Sixt-sur-Aff's tap water?
Yes. On the main network, the PFAS-4 sum rose from 1.9 ng/L (21 July 2025) to 3.06 ng/L (19 May 2026) across 3 quantified checks. pfasnearme's benchmark is 0.5 ng/L as an annual mean. These history statistics use laboratory-published sums only.
How hard is the water in Sixt-sur-Aff?
The water hardness in Sixt-sur-Aff is 14.2 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
