PFAS in drinking water

None of the 4 most harmful 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, 1 ng/L found in total
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.

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.

None found. The lab sees nothing below 4 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Fère-Champenoise, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 16 May 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: 1 ng/L (0.001 µg/L), below the EU legal limit (100 ng/L). 2 checks since 29 April 2025: sum of 20 PFAS up to 1 ng/L, sometimes below the detection limit.

PFAS over time in Fère-Champenoise

2 PFAS checks since 29 April 2025, from the published measurements. Samples come from 2 distribution networks. The trend refers to the network “FERE CHAMPENOISE”.

“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 Fère-Champenoise safe to drink?

All the values shown here (22 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 Fère-Champenoise'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 Fère-Champenoise 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 Fère-Champenoise'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 Fère-Champenoise?

The water hardness in Fère-Champenoise is 24.5 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
