PFAS in drinking water

8× above our health benchmark

Amount found in the water 4 ng/L 0.004 µg/L · the 4 most harmful PFAS (PFAS-4)
Our health benchmark 0.5 ng/L

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 Dangers, on the same distribution network as Mittainvilliers-Vérigny (DANGERS-MITTAINVIL-VERIGNY). 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 Mittainvilliers-Vérigny, the 4 most closely watched PFAS (PFAS-4) add up to 4 ng/L (0.004 µg/L) at the latest PFAS check on 23 June 2026. That's 8 times our 0.5 ng/L health benchmark, exactly at Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 6 ng/L (0.006 µg/L), below the EU legal limit (100 ng/L). Sampled in Dangers, on the same network. 2 checks since 10 September 2025: sum of 20 PFAS from 4 ng/L to 6 ng/L. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

PFAS over time in Mittainvilliers-Vérigny

2 PFAS checks since 10 September 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Mittainvilliers-Vérigny.

“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 Mittainvilliers-Vérigny safe to drink?

At the latest check, the water was over at least one limit. “Eau de qualité bactériologique conforme aux exigences de qualité en vigueur pour l’ensemble des paramètres mesurés. Eau de qualité chimique non conforme en raison du dépassement de la limite de qualité pour le paramètre plomb. Cette teneur en plomb ne vaut que pour le point d'utilisation où elle a été mesurée. Compte tenu de l'influence du réseau de distribution d'eau (réseau intérieur et éventuellement branchement public) sur la dissolution des métaux, cette valeur n’est pas représentative de la qualité de l'eau pour l'ensemble des consommateurs du réseau de distribution.”

How high are PFAS levels in Mittainvilliers-Vérigny's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 6 ng/L. The EU limit is 100 ng/L, so this water is at 6 % of the limit. (below the EU limit)

Does the water in Mittainvilliers-Vérigny 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 4 ng/L stays below.

Are PFAS levels rising in Mittainvilliers-Vérigny's tap water?

Calculated PFAS-4 values are listed in the table. The chart uses laboratory-published sum-of-20 results; there are too few laboratory-published PFAS-4 sums for the existing trend calculation.

How hard is the water in Mittainvilliers-Vérigny?

The water hardness in Mittainvilliers-Vérigny is 23 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
