PFAS in Montélimar's tap water: 6 ng/L, 12x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
12× 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.
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 Montélimar, 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). 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. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions
Is tap water in Montélimar safe to drink?
Yes. At the check on 23 July 2026, the tap water in Montélimar was within every limit tested. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité pour la température de l'eau (la référence d e qualité étant fixée à 25°C).”
How high are PFAS levels in Montélimar'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 Montélimar 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 Montélimar'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 Montélimar?
The water hardness in Montélimar is 20.8 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
