PFAS in Le Fréty'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.
Sample taken in Givron, on the same distribution network as Le Fréty (S60 ROCQUIGNY ET ENVIRONS). 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.

Frequently asked questions
Is tap water in Le Fréty safe to drink?
Yes. At the check on 29 April 2026, the tap water in Le Fréty was within every limit tested. Outside a reference value: Coliform bacteria 4 n/(100mL) on 7 April 2025 (reference ≤ 0 mL)). These are indicator parameters with reference values, not legal limits. “Eau destinée à la consommation humaine conforme pour l'ensemble des paramètres analysés. Toutefois, la référence de qualité(norme non impérative) relative à la numération des bactéries coliformes n'est pas satisfaite. Une vérification des installations peut s'avérer nécessaire, notamment le traitement de désinfection s'il existe. L’ammonium présent dans l’eau étant d’origine naturelle, la référence de qualité est de 0,5 mg/L. Les résultats de l’analyse montrent une teneur conforme à la référence indiquée.”
How high are PFAS levels in Le Fréty'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 Le Fréty 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.
How hard is the water in Le Fréty?
No hardness value is available for Le Fréty in this source.
