PFAS in drinking water

No PFAS detected

Amount found in the water < 4 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, none found
Our health benchmark 0.5 ng/L

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.

Sample taken in Rayol-Canadel-sur-Mer, on the same distribution network as Cavalaire-sur-Mer (ADDUCT. RAYOL CAVALAIRE LA MOLE). 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.

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.

None found. The lab sees nothing below 4 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Cavalaire-sur-Mer, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 17 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). Sampled in Rayol-Canadel-sur-Mer, on the same network. 3 checks since 18 March 2026: PFAS-4 up to 6 ng/L, sometimes below the detection limit.

PFAS over time in Cavalaire-sur-Mer

5 PFAS checks since 27 November 2024, from the published measurements. Samples from 5 communes on the same network: it's the same water, so each one applies to Cavalaire-sur-Mer. Samples come from 2 distribution networks. The trend refers to the network “ADDUCTION SAINT TROPEZ-SIDECM”.

“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Frequently asked questions

Is tap water in Cavalaire-sur-Mer safe to drink?

Yes. At the check on 17 July 2026, the tap water in Cavalaire-sur-Mer 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.”

How high are PFAS levels in Cavalaire-sur-Mer'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 Cavalaire-sur-Mer 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 Cavalaire-sur-Mer's tap water?

Too few quantified checks to say (1 since 27 November 2024). 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 Cavalaire-sur-Mer?

The water hardness in Cavalaire-sur-Mer is 12.1 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?
