PFAS in Fréville-du-Gâtinais's tap water: under 4 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
None of the 4 most harmful 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 Boiscommun, on the same distribution network as Fréville-du-Gâtinais (SYNDICAT DES EAUX DE BOISCOMMUN). 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.

In Fréville-du-Gâtinais, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 13 January 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: 27 ng/L (0.027 µg/L), below the EU legal limit (100 ng/L). Sampled in Boiscommun, on the same network. 2 checks since 11 February 2025: sum of 20 PFAS up to 27 ng/L, sometimes below the detection limit.

Frequently asked questions
Is tap water in Fréville-du-Gâtinais safe to drink?
Yes. At the check on 21 May 2026, the tap water in Fréville-du-Gâtinais was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”
How high are PFAS levels in Fréville-du-Gâtinais's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 27 ng/L. The EU limit is 100 ng/L, so this water is at 27 % of the limit. (below the EU limit)
Does the water in Fréville-du-Gâtinais 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 Fréville-du-Gâtinais's tap water?
Calculated PFAS-4 values are listed in the table. The chart uses laboratory-published sum-of-20 results; there are too few laboratory-published PFAS-4 sums for the existing trend calculation.
How hard is the water in Fréville-du-Gâtinais?
The water hardness in Fréville-du-Gâtinais is 22 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
