PFAS in Hangard's tap water: 2 ng/L, 4x our 0.5 ng/L benchmark

Last PFAS check: · Source: Hub'eau

PFAS in drinking water

4× above our health benchmark

Amount found in the water 2 ng/L 0.002 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 Berteaucourt-lès-Thennes, on the same distribution network as Hangard (BERTEAUCOURT LES THENNES UDI). 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).

More PFAS than in 85% of the cities we track

In Hangard, the 4 most closely watched PFAS (PFAS-4) add up to 2 ng/L (0.002 µg/L) at the latest PFAS check on 24 January 2025. That's 4 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 3 ng/L (0.003 µg/L), below the EU legal limit (100 ng/L). Sampled in Berteaucourt-lès-Thennes, 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 Hangard safe to drink?

All the values shown here (16 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 Hangard's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 3 ng/L. The EU limit is 100 ng/L, so this water is at 3 % of the limit. (below the EU limit)

Does the water in Hangard 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 ng/L stays below.

How hard is the water in Hangard?

No hardness value is available for Hangard 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 21 September 2026.
