PFAS in La Verpillière's tap water: 25 ng/L, 50x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
50× 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 La Verpillière, the 4 most closely watched PFAS (PFAS-4) add up to 25 ng/L (0.025 µg/L) at the latest PFAS check on 15 July 2026. That's 50 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 66 ng/L (0.066 µg/L), below the EU legal limit (100 ng/L). 10 checks since 13 August 2025: PFAS-4 from 17 ng/L to 37 ng/L, averaging 29 ng/L over 12 months. No clear trend.

Frequently asked questions
Is tap water in La Verpillière safe to drink?
All the values shown here (31 July 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”
How high are PFAS levels in La Verpillière's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 66 ng/L. The EU limit is 100 ng/L, so this water is at 66 % of the limit. (below the EU limit)
Does the water in La Verpillière also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 25 ng/L. That is 6.3 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 La Verpillière's tap water?
No clear trend. Since 15 April 2024, 10 checks have been published; on the main network the PFAS-4 sum ranged between 25 ng/L and 37 ng/L (6 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 La Verpillière?
The water hardness in La Verpillière is 27.3 °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 21 September 2026.
