PFAS in Bordères-sur-l'Échez's tap water: 4.2 ng/L, 8.4x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
8.4× 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).

Yes. At the check on 10 July 2026, the tap water in Bordères-sur-l'Échez was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”
How high are PFAS levels in Bordères-sur-l'Échez's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 23 ng/L. The EU limit is 100 ng/L, so this water is at 23 % of the limit. (below the EU limit)
Does the water in Bordères-sur-l'Échez also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 4.2 ng/L. That is 1.05 times Sweden's legal limit of 4 ng/L, in force since 2026. Germany will set a similar one in 2028. The water still passes the current EU legal limit (100 ng/L for the total of 20 PFAS).
Are PFAS levels rising in Bordères-sur-l'Échez'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 Bordères-sur-l'Échez?
The water hardness in Bordères-sur-l'Échez is 11.8 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
