PFAS in Roquebrune-sur-Argens's tap water: under 4 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
No PFAS detected
The lab sees nothing below 4 ng/L, 8 times our benchmark of 0.5 ng/L. Water above our benchmark would pass this check unnoticed.
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.
The lab detects each of the four substances from 1 ng/L upward. None reached that limit, so their total is below 4 ng/L rather than zero.

In Roquebrune-sur-Argens, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 28 April 2026. The total is below 4 ng/L, the sum of the detection limits and 8 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,029 µg/L, below the EU legal limit (100 ng/L). 3 checks since 12 February 2026: PFAS-4 up to 2 ng/L, sometimes below the detection limit.

Frequently asked questions
Is tap water in Roquebrune-sur-Argens safe to drink?
At the latest check, the water was over at least one limit. “Eau non conforme aux limites de qualité fixées par le Code de la Santé Publique concernant les eaux destinées à la consommation humaine pour le paramètre trihalométhanes. Les trihalométhanes sont des sous-produits de désinfection (réaction du chlore sur une eau trop chargée en matière organique). La concentration doit rester la plus faible possible. En application des articles R.1321-27 et R.1321-30, la Personne Responsable de la Production/Distribution d'Eau doit prendre les mesures de correction nécessaires et informe l'ARS (DD 83) de l'application des mesures prises. A noter le dépassement de la référence de qualité pour le paramètre conductivité. Une vigilance particulière doit être accordée à la surveillance de la corrosion du réseau. 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.”
How high are PFAS levels in Roquebrune-sur-Argens's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 29 ng/L. The EU limit is 100 ng/L, so this water is under 29 % of the limit. (below the EU limit)
Does the water in Roquebrune-sur-Argens also meet the strictest limits in Europe?
As far as this check can tell, yes. None of the four compounds was quantified, so their total is below 4 ng/L, the sum of the laboratory's detection limits, and under Sweden's legal limit of 4 ng/L in force since 2026.
Are PFAS levels rising in Roquebrune-sur-Argens's tap water?
Too few quantified checks to say (0 since 13 March 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values. These history statistics use laboratory-published sums only.
How hard is the water in Roquebrune-sur-Argens?
The water hardness in Roquebrune-sur-Argens is 30.2 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
