PFAS in La Neuville-du-Bosc's tap water: under 6 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 6 ng/L, 12 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 1 to 2 ng/L upward. None reached that limit, so their total is below 6 ng/L rather than zero.

In La Neuville-du-Bosc, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 9 April 2025. The total is below 6 ng/L, the sum of the detection limits and 12 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <SEUIL µg/L, below the EU legal limit (100 ng/L). 2 checks since 9 April 2025, sum of 20 PFAS always below the detection limit.

PFAS over time in La Neuville-du-Bosc
2 PFAS checks since 9 April 2025, from the published measurements. Samples come from 2 distribution networks. The trend refers to the network “ECARDENVILLE LA CAMPAGNE”.
“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 | Network |
|---|---|---|---|
| < 6 ng/L · calculated | < detection limit | ECARDENVILLE LA CAMPAGNE | |
| < 6 ng/L · calculated | < detection limit | 076002012 |
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 La Neuville-du-Bosc safe to drink?
At the latest check, the water was over at least one limit. “Eau d'alimentation non-conforme à la limite de qualité pour les nitrat es et conforme aux références de qualité. L'analyse de recontrôle effe ctuée le 29 juin 2026 est conforme.”
How high are PFAS levels in La Neuville-du-Bosc's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at –. The EU limit is 100 ng/L, so this water is at – of the limit. (below the EU limit)
Does the water in La Neuville-du-Bosc 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 6 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 La Neuville-du-Bosc'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-du-Bosc?
The water hardness in La Neuville-du-Bosc is 32.2 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
