PFAS in drinking water

12× above our health benchmark

Amount found in the water 6 ng/L 0.006 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 Montélimar, on the same distribution network as Châteauneuf-du-Rhône (MONTELIMAR CATALINS). 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 Châteauneuf-du-Rhône, the 4 most closely watched PFAS (PFAS-4) add up to 6 ng/L (0.006 µg/L) at the latest PFAS check on 30 June 2026. That's 12 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 18 ng/L (0.018 µg/L), below the EU legal limit (100 ng/L). Sampled in Montélimar, on the same network. 7 checks since 9 July 2025: PFAS-4 up to 6 ng/L, sometimes below the detection limit, averaging 4.8 ng/L over 12 months. No clear trend.

PFAS over time in Châteauneuf-du-Rhône

18 PFAS checks since 1 March 2023, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Châteauneuf-du-Rhône. Samples come from 2 distribution networks. The trend refers to the network “MONTELIMAR CATALINS”.

“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 Châteauneuf-du-Rhône safe to drink?

Yes. At the check on 9 July 2026, the tap water in Châteauneuf-du-Rhône was within every limit tested. “Eau d'alimentation conforme aux limites de qualité en vigueur. La référence de qualité fixée à 25°C pour la température est dépassée. Ce paramètre n'est représentatif que du lieu de prélèvement.”

How high are PFAS levels in Châteauneuf-du-Rhône's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 18 ng/L. The EU limit is 100 ng/L, so this water is at 18 % of the limit. (below the EU limit)

Does the water in Châteauneuf-du-Rhône also meet the strictest limits in Europe?

No. The four most harmful PFAS add up to 6 ng/L. That is 1.5 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 Châteauneuf-du-Rhône's tap water?

No clear trend. Since 1 March 2023, 7 checks have been published; on the main network the PFAS-4 sum ranged between 2 ng/L and 6 ng/L (5 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 Châteauneuf-du-Rhône?

The water hardness in Châteauneuf-du-Rhône is 47.2 °f (hard). 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.
