PFAS in Bretigny's tap water: under 2.5 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 2.5 ng/L, 5 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.
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 0.5 to 1 ng/L upward. None reached that limit, so their total is below 2.5 ng/L rather than zero.

In Bretigny, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 8 July 2026. The total is below 2.5 ng/L, the sum of the detection limits and 5 times our 0.5 ng/L benchmark. Sum of 20 PFAS: 12.04 ng/L (0.012 µg/L), below the EU legal limit (100 ng/L). 2 checks since 24 June 2025: sum of 20 PFAS up to 12.04 ng/L, sometimes below the detection limit.

PFAS over time in Bretigny
2 PFAS checks since 24 June 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Bretigny.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.
| Date | PFAS-4 | Sum of 20 PFAS | Sampled at |
|---|---|---|---|
| < detection limit | 12.04 ng/L | Bretigny | |
| < 2.5 ng/L · calculated | < detection limit | Norges-la-Ville |
Calculated values: “<” is an upper bound from published thresholds, “≥” a lower bound, “–” means no published sum or complete measurement. How to read a PFAS result

Frequently asked questions
Is tap water in Bretigny safe to drink?
At the latest check, the water was over at least one limit. “Eau non conforme pour le paramètre plomb au point de prélèvement (cette valeur n'est pas représentative de la qualité de l'eau pour l'ensemble des consommateurs du réseau). Une enquête doit être effectuée immédiatement afin de déterminer les causes (réseau intérieur et/ou branchement public en plomb) suivie de mesures correctives pour rétablir la qualité de l'eau. A l’adresse du prélèvement, il est recommandé de ne pas utiliser l’eau à des fins alimentaires pour les enfants de moins de 7 ans et les femmes enceintes.”
How high are PFAS levels in Bretigny's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 12.04 ng/L. The EU limit is 100 ng/L, so this water is at 12 % of the limit. (below the EU limit)
Does the water in Bretigny 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 2.5 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 Bretigny'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 Bretigny?
The water hardness in Bretigny is 28.4 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
