PFAS in Couvrot's tap water: 4 ng/L, 8x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
8× above our health benchmark
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.
Substances below the detection limit count as 0, so the real total may be higher.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

In Couvrot, the 4 most closely watched PFAS (PFAS-4) add up to 4 ng/L (0.004 µg/L) at the latest PFAS check on 16 February 2026. That's 8 times our 0.5 ng/L health benchmark, exactly at Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 8 ng/L (0.008 µg/L), below the EU legal limit (100 ng/L). 2 checks since 23 June 2025: sum of 20 PFAS from 8 ng/L to 8 ng/L.

PFAS over time in Couvrot
2 PFAS checks since 23 June 2025, from the published measurements.
“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 |
|---|---|---|
| 4 ng/L – < 5 ng/L · calculated | 8 ng/L | |
| 5 ng/L – < 7 ng/L · calculated | 8 ng/L |
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 Couvrot safe to drink?
All the values shown here (10 July 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “L'eau distribuée présente des concentrations en pesticides supérieures aux exigences réglementaires fixées à 0,1 µg/l, mais inférieures aux valeurs définies pour en limiter les usages sanitaires. Un contrôle renforcé est en place et des actions sont engagées par l’exploitant pour restaurer la qualité de l’eau. Cette eau est de bonne qualité pour les autres paramètres. Elle peut être consommée par tous.”
How high are PFAS levels in Couvrot's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 8 ng/L. The EU limit is 100 ng/L, so this water is at 8 % of the limit. (below the EU limit)
Does the water in Couvrot also meet the strictest limits in Europe?
Yes. Even against Europe's strictest legal limit, Sweden's 4 ng/L in force since 2026, the measured value of 4 ng/L stays below.
Are PFAS levels rising in Couvrot'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 Couvrot?
The water hardness in Couvrot is 27.2 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
