PFAS in Bazoches'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 Monceaux-le-Comte, on the same distribution network as Bazoches (RESEAU DU BOURG DE BAZOCHES DN). 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.

Frequently asked questions
Is tap water in Bazoches safe to drink?
At the latest check, the water was over at least one limit. “Les résultats ont mis en évidence un dépassement de la limite de quali té pour le paramètre fluorure (1.7 mg/l pour une limite de qualité fix ée à 1,5 mg/l). Votre réseau étant alimenté par le réseau du SIAEP de Charles Chaigneau, il a été demandé à ce dernier de rechercher l’origi ne de ce dépassement et de mettre en oeuvre les actions nécessaires af in de retrouver une qualité d'eau conforme à la réglementation. Un prélèvement de recontrôle est programmé à la statio n du SIAEP de Charles Chaigneau. Les autres paramètres mesurés réponde nt aux normes de potabilité.”
How high are PFAS levels in Bazoches's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 10 ng/L. The EU limit is 100 ng/L, so this water is at 10 % of the limit. (below the EU limit)
Does the water in Bazoches 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 Bazoches?
The water hardness in Bazoches is 29 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
