PFAS in Mouans-Sartoux's tap water: 29 ng/L, 58x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
58× 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 Mouans-Sartoux, the 4 most closely watched PFAS (PFAS-4) add up to 29 ng/L (0.029 µg/L) at the latest PFAS check on 2 July 2026. That's 58 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 79 ng/L (0.079 µg/L), below the EU legal limit (100 ng/L). 8 checks since 29 January 2026: PFAS-4 up to 29 ng/L, sometimes below the detection limit, averaging at least 12 ng/L over 12 months (non-detects as 0).

Frequently asked questions
Is tap water in Mouans-Sartoux safe to drink?
Yes. At the check on 24 July 2026, the tap water in Mouans-Sartoux 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 Mouans-Sartoux's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 79 ng/L. The EU limit is 100 ng/L, so this water is at 79 % of the limit. (below the EU limit)
Does the water in Mouans-Sartoux also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 29 ng/L. That is 7.3 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 Mouans-Sartoux's tap water?
Yes. On the main network, the PFAS-4 sum rose from 3 ng/L (29 January 2026) to 29 ng/L (2 July 2026) across 7 quantified checks. pfasnearme's benchmark is 0.5 ng/L as an annual mean. These history statistics use laboratory-published sums only.
How hard is the water in Mouans-Sartoux?
The water hardness in Mouans-Sartoux is 29.4 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
