PFAS in Chimilin's tap water: 4 ng/L, 8x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
8× above our health benchmark
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 Les Abrets en Dauphiné, on the same distribution network as Chimilin (ABRETS SUD). 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 90% of the cities we track

In Chimilin, the 4 most closely watched PFAS (PFAS-4) add up to 4 ng/L (0.004 µg/L) at the latest PFAS check on 15 April 2026. That's 8 times our 0.5 ng/L health benchmark, exactly at Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 4 ng/L (0.004 µg/L), below the EU legal limit (100 ng/L). Sampled in Les Abrets en Dauphiné, on the same network. 3 checks since 6 August 2025: PFAS-4 from 4 ng/L to 5 ng/L, averaging 4.33 ng/L over 12 months. No clear trend.

Frequently asked questions
Is tap water in Chimilin safe to drink?
Yes. At the check on 15 April 2026, the tap water in Chimilin was within every limit tested. Outside a reference value: Coliform bacteria 1 n/(100mL) on 19 March 2026 (reference ≤ 0 mL)). These are indicator parameters with reference values, not legal limits. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité.”
How high are PFAS levels in Chimilin's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 4 ng/L. The EU limit is 100 ng/L, so this water is at 4 % of the limit. (below the EU limit)
Does the water in Chimilin 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 4 ng/L stays below.
Are PFAS levels rising in Chimilin's tap water?
No clear trend. Since 6 August 2025, 3 checks have been published; on the main network the PFAS-4 sum ranged between 4 ng/L and 5 ng/L (3 quantified values), at times below the detection limit. pfasnearme only reports a trend from a change of at least 25 % and 1 ng/L.
How hard is the water in Chimilin?
The water hardness in Chimilin is 29.1 °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.
