PFAS in drinking water

No PFAS detected

Amount found in the water < 4 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, none found
Our health benchmark 0.5 ng/L

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 Wasigny, on the same distribution network as La Neuville-lès-Wasigny (S24 CROIX BAUDOIN). 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 La Neuville-lès-Wasigny, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 19 May 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: <0,029 µg/L, below the EU legal limit (100 ng/L). Sampled in Wasigny, on the same network. 2 checks since 2 June 2025, sum of 20 PFAS always below the detection limit (29 ng/L).

PFAS over time in La Neuville-lès-Wasigny

2 PFAS checks since 2 June 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to La Neuville-lès-Wasigny.

“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Frequently asked questions

Is tap water in La Neuville-lès-Wasigny safe to drink?

At the latest check, the water was over at least one limit. “Eau d'alimentation non conforme aux exigences de qualité en vigueur sur le plan bactériologique. Dans ces conditions, il vous appartient de mettre en œuvre toute mesure adaptée pour identifier l’origine de cette mauvaise qualité et d’y remédier. Vous pouvez notamment procéder au nettoyage et à la désinfection des installations. Un prélè vement de contrôle est prévu dans les prochains jours.”

How high are PFAS levels in La Neuville-lès-Wasigny's drinking water?

At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 29 ng/L. The EU limit is 100 ng/L, so this water is under 29 % of the limit. (below the EU limit)

Does the water in La Neuville-lès-Wasigny 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 La Neuville-lès-Wasigny'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 La Neuville-lès-Wasigny?

The water hardness in La Neuville-lès-Wasigny is 32.3 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
