PFAS in drinking water

42× above our health benchmark

Amount found in the water 21 ng/L 0.021 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.

How we chose 0.5 ng/L

Sample taken in La Chapelle-Villars, on the same distribution network as Chuyer (CCPR VIEILL.CHAPELLE). The health authority samples one tap per network; a network carries the same treated water everywhere.

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 Chuyer, the 4 most closely watched PFAS (PFAS-4) add up to 21 ng/L (0.021 µg/L) at the latest PFAS check on 21 April 2026. That's 42 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 56 ng/L (0.056 µg/L), below the EU legal limit (100 ng/L). Sampled in La Chapelle-Villars, on the same network. 12 checks since 18 September 2025: PFAS-4 from 7 ng/L to 26 ng/L, averaging 21.33 ng/L over 12 months. No clear trend.

PFAS over time in Chuyer

42 PFAS checks since 7 December 2023, from the published measurements. Samples from 8 communes on the same network: it's the same water, so each one applies to Chuyer. Samples come from 2 distribution networks. The trend refers to the network “CCPR VIEILL.CHAPELLE”.

“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 Chuyer safe to drink?

All the values shown here (21 April 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 Chuyer's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 56 ng/L. The EU limit is 100 ng/L, so this water is at 56 % of the limit. (below the EU limit)

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

No. The four most harmful PFAS add up to 21 ng/L. That is 5.3 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 Chuyer's tap water?

No clear trend. Since 7 December 2023, 12 checks have been published; on the main network the PFAS-4 sum ranged between 18 ng/L and 26 ng/L (9 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 Chuyer?

The water hardness in Chuyer is 19.8 °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 12 September 2026.
