PFAS in drinking water

18× above our health benchmark

Amount found in the water 9 ng/L 0.009 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 Naours, on the same distribution network as Beauval (NAOURS 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).

In Beauval, the 4 most closely watched PFAS (PFAS-4) add up to 9 ng/L (0.009 µg/L) at the latest PFAS check on 7 July 2026. That's 18 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 9 ng/L (0.009 µg/L), below the EU legal limit (100 ng/L). Sampled in Naours, on the same network. 7 checks since 5 August 2025: PFAS-4 up to 27 ng/L, sometimes below the detection limit, averaging 19 ng/L over 12 months. Falling on the main network.

PFAS over time in Beauval

10 PFAS checks since 21 February 2025, from the published measurements. Samples from 6 communes on the same network: it's the same water, so each one applies to Beauval. Samples come from 2 distribution networks. The trend refers to the network “NAOURS UDI”.

“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 Beauval safe to drink?

Yes. At the check on 7 July 2026, the tap water in Beauval 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 Beauval's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 9 ng/L. The EU limit is 100 ng/L, so this water is at 9 % of the limit. (below the EU limit)

Does the water in Beauval also meet the strictest limits in Europe?

No. The four most harmful PFAS add up to 9 ng/L. That is 2.3 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 Beauval's tap water?

No, they are falling. On the main network, the PFAS-4 sum went from 18 ng/L (29 August 2025) to 9 ng/L (7 July 2026) across 5 quantified checks. These history statistics use laboratory-published sums only.

How hard is the water in Beauval?

The water hardness in Beauval is 28.9 °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.

Same water network

Same distribution network as Beauval, so in principle the same water.
