PFAS in the tap water of Villereau (Nord): 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 Locquignol, on the same distribution network as Villereau (LOCQUIGNOL). 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 Villereau, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 8 April 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: 1 ng/L (0.001 µg/L), below the EU legal limit (100 ng/L). Sampled in Locquignol, on the same network. 3 checks since 26 January 2026: PFAS-4 up to 3 ng/L, sometimes below the detection limit.

PFAS over time in Villereau
3 PFAS checks since 26 January 2026, values as published. Samples from 3 communes on the same network: it's the same water, so each one applies to Villereau. Samples come from 2 distribution networks. The trend refers to the network “LOCQUIGNOL”.
| Date | PFAS-4 | Sum of 20 PFAS | Sampled at | Network |
|---|---|---|---|---|
| < 1 ng/L | 1 ng/L | Locquignol | LOCQUIGNOL | |
| 3 ng/L | 5 ng/L | Boussières-sur-Sambre | GOMMEGNIES | |
| 1 ng/L | 1 ng/L | Villers-Pol | LOCQUIGNOL |
“<” means not detected, the figure being the detection limit. “–” means not published. Labs have only reported the PFAS-4 sum (SANDRE code 9268) since autumn 2025. How to read a PFAS result

Frequently asked questions
Is tap water in Villereau safe to drink?
Yes. At the check on 9 June 2026, the tap water in Villereau 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 Villereau's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 1 ng/L. The EU limit is 100 ng/L, so this water is at 1 % of the limit. (below the EU limit)
Does the water in Villereau 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 Villereau's tap water?
Too few quantified checks to say (1 since 26 January 2026). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.
How hard is the water in Villereau?
No hardness value is available for Villereau in this source.
Where does this data come from?
All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 21 September 2026.
Same water network
Same distribution network as Villereau, so in principle the same water.
