PFAS in La Chapelle-en-Valgaudémar's tap water: under 4 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 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.
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 Chapelle-en-Valgaudémar, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 10 July 2025. 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: <0,028 µg/L, below the EU legal limit (100 ng/L). 6 checks since 5 November 2024: sum of 20 PFAS up to 1 ng/L, sometimes below the detection limit.

Frequently asked questions
Is tap water in La Chapelle-en-Valgaudémar safe to drink?
At the latest check, the water was over at least one limit. “Eau d'alimentation non-conforme aux exigences de qualité.”
How high are PFAS levels in La Chapelle-en-Valgaudémar's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 28 ng/L. The EU limit is 100 ng/L, so this water is under 28 % of the limit. (below the EU limit)
Does the water in La Chapelle-en-Valgaudémar 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 Chapelle-en-Valgaudémar'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 Chapelle-en-Valgaudémar?
The water hardness in La Chapelle-en-Valgaudémar is 4.3 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
