PFAS in Sucy-en-Brie's tap water: under 8 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 8 ng/L, 16 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 Mandres-les-Roses, on the same distribution network as Sucy-en-Brie (L.BELLE ÉTOILE). 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 2 ng/L upward. None reached that limit, so their total is below 8 ng/L rather than zero.

In Sucy-en-Brie, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 17 July 2026. The total is below 8 ng/L, the sum of the detection limits and 16 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,005 µg/L, below the EU legal limit (100 ng/L). Sampled in Mandres-les-Roses, on the same network. 29 checks since 9 April 2025: sum of 20 PFAS up to 13 ng/L, sometimes below the detection limit.

Frequently asked questions
Is tap water in Sucy-en-Brie safe to drink?
Yes. At the check on 30 July 2026, the tap water in Sucy-en-Brie 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 Sucy-en-Brie's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 5 ng/L. The EU limit is 100 ng/L, so this water is under 5 % of the limit. (below the EU limit)
Does the water in Sucy-en-Brie 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 8 ng/L, above Sweden's legal limit of 4 ng/L in force since 2026, so a value between the two would go unnoticed.
Are PFAS levels rising in Sucy-en-Brie'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 Sucy-en-Brie?
The water hardness in Sucy-en-Brie is 25.5 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
