PFAS in Pavezin's tap water: 20 ng/L, 40x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
40× 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.
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 Pavezin, the 4 most closely watched PFAS (PFAS-4) add up to 20 ng/L (0.02 µg/L) at the latest PFAS check on 11 June 2026. That's 40 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 54 ng/L (0.054 µg/L), below the EU legal limit (100 ng/L). 6 checks since 11 September 2025: PFAS-4 from 12 ng/L to 24 ng/L, averaging 19.5 ng/L over 12 months.

PFAS over time in Pavezin
24 PFAS checks since 7 March 2023, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Pavezin. Samples come from 2 distribution networks. The trend refers to the network “SEM PAVEZIN SIEMLY”.
“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 Pavezin safe to drink?
Yes. At the check on 11 June 2026, the tap water in Pavezin 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 Pavezin's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 54 ng/L. The EU limit is 100 ng/L, so this water is at 54 % of the limit. (below the EU limit)
Does the water in Pavezin also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 20 ng/L. That is 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 Pavezin's tap water?
Yes. On the main network, the PFAS-4 sum rose from 15 ng/L (11 September 2025) to 20 ng/L (11 June 2026) across 6 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 Pavezin?
The water hardness in Pavezin is 22.4 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
