PFAS in the tap water of Rouvray (Eure): 2.2 ng/L, 4.4x our 0.5 ng/L benchmark

Last PFAS check: · Source: Hub'eau

PFAS in drinking water

4.4× above our health benchmark

Amount found in the water 2.2 ng/L 0.0022 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 Chambray, on the same distribution network as Rouvray (HOULBEC COCHEREL). 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 Rouvray, the 4 most closely watched PFAS (PFAS-4) add up to 2.2 ng/L (0.0022 µg/L) at the latest PFAS check on 26 February 2025. That's 4.4 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 5.4 ng/L (0.0054 µg/L), below the EU legal limit (100 ng/L). Sampled in Chambray, on the same network. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions

Is tap water in Rouvray safe to drink?

Yes. At the check on 1 October 2025, the tap water in Rouvray 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 Rouvray's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 5.4 ng/L. The EU limit is 100 ng/L, so this water is at 5 % of the limit. (below the EU limit)

Does the water in Rouvray 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 2.2 ng/L stays below.

How hard is the water in Rouvray?

No hardness value is available for Rouvray in this source.

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 12 September 2026.

Same water network
