PFAS in Beausemblant's tap water: 10 ng/L, 20x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
20× 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 Moras-en-Valloire, on the same distribution network as Beausemblant (S VALLOIRE MANTHES). 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 Beausemblant, the 4 most closely watched PFAS (PFAS-4) add up to 10 ng/L (0.01 µg/L) at the latest PFAS check on 2 April 2026. That's 20 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 32 ng/L (0.032 µg/L), below the EU legal limit (100 ng/L). Sampled in Moras-en-Valloire, on the same network. 6 checks since 17 July 2025: PFAS-4 up to 15 ng/L, sometimes below the detection limit, averaging 11.25 ng/L over 12 months. No clear trend.

PFAS over time in Beausemblant
16 PFAS checks since 17 March 2023, from the published measurements. Samples from 3 communes on the same network: it's the same water, so each one applies to Beausemblant. Samples come from 2 distribution networks. The trend refers to the network “S VALLOIRE MANTHES”.
“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 Beausemblant safe to drink?
Yes. At the check on 4 May 2026, the tap water in Beausemblant 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 Beausemblant's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 32 ng/L. The EU limit is 100 ng/L, so this water is at 32 % of the limit. (below the EU limit)
Does the water in Beausemblant also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 10 ng/L. That is 2.5 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 Beausemblant's tap water?
No clear trend. Since 17 March 2023, 6 checks have been published; on the main network the PFAS-4 sum ranged between 9 ng/L and 15 ng/L (4 quantified values), at times below the detection limit. pfasnearme only reports a trend from a change of at least 25 % and 1 ng/L. These history statistics use laboratory-published sums only.
How hard is the water in Beausemblant?
The water hardness in Beausemblant is 35.4 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
