PFAS in Fresles's tap water: under 5 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 5 ng/L, 10 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 Torcy-le-Grand, on the same distribution network as Fresles (TORCY-LE-GRAND). 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 to 2 ng/L upward. None reached that limit, so their total is below 5 ng/L rather than zero.

None found. The lab sees nothing below 5 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Fresles, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 31 March 2025. The total is below 5 ng/L, the sum of the detection limits and 10 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <SEUIL µg/L, below the EU legal limit (100 ng/L). Sampled in Torcy-le-Grand, on the same network. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions
Is tap water in Fresles safe to drink?
Yes. At the check on 28 October 2025, the tap water in Fresles was within every limit tested. “Eau Conforme aux exigences de qualité sur le prélèvement réalisé. Il s'agit d'un nouveau contrôle effectué après une non conformité bactériologique.”
How high are PFAS levels in Fresles's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at –. The EU limit is 100 ng/L, so this water is at – of the limit. (below the EU limit)
Does the water in Fresles also meet the strictest limits in Europe?
The check cannot say. None of the four compounds was quantified, but the laboratory's detection limits add up to 5 ng/L, above Sweden's legal limit of 4 ng/L in force since 2026, so a value between the two would go unnoticed.
How hard is the water in Fresles?
No hardness value is available for Fresles in this source.
