PFAS in drinking water

16× above our health benchmark

Amount found in the water 8 ng/L 0.008 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.

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 Hyères, the 4 most closely watched PFAS (PFAS-4) add up to 8 ng/L (0.008 µg/L) at the latest PFAS check on 27 July 2026. That's 16 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 16 ng/L (0.016 µg/L), below the EU legal limit (100 ng/L). 9 checks since 16 January 2026: PFAS-4 from 8 ng/L to 29 ng/L, averaging 23.43 ng/L over 12 months. No clear trend.

Frequently asked questions

Is tap water in Hyères safe to drink?

Yes. At the check on 27 July 2026, the tap water in Hyères was within every limit tested. “Eau conforme aux limites de qualité fixées par le Code de la Santé Publique concernant les eaux destinées à la consommation humaine pour les paramètres recherchés. A noter le dépassement de la référence de qualité pour le paramètre température. Les températures élevées peuvent favoriser les développements microbiens. Des actions doivent être mises en oeuvre afin d'isoler les canalisations pour respecter la référence de qualité. Eau incrustante.”

How high are PFAS levels in Hyères's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 16 ng/L. The EU limit is 100 ng/L, so this water is at 16 % of the limit. (below the EU limit)

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

No. The four most harmful PFAS add up to 8 ng/L. That is 2 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 Hyères's tap water?

No clear trend. Since 4 November 2024, 9 checks have been published; on the main network the PFAS-4 sum ranged between 20 ng/L and 29 ng/L (7 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 Hyères?

The water hardness in Hyères is 36.8 °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.
