PFAS in Le Buisson-de-Cadouin'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 Le Buisson-de-Cadouin, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 9 March 2026. 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). 3 checks since 11 February 2026: PFAS-4 up to 2 ng/L, sometimes below the detection limit.

Frequently asked questions
Is tap water in Le Buisson-de-Cadouin safe to drink?
Yes. At the check on 20 July 2026, the tap water in Le Buisson-de-Cadouin was within every limit tested. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité.”
How high are PFAS levels in Le Buisson-de-Cadouin'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 Le Buisson-de-Cadouin 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 Le Buisson-de-Cadouin's tap water?
Too few quantified checks to say (0 since 12 May 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values. These history statistics use laboratory-published sums only.
How hard is the water in Le Buisson-de-Cadouin?
The water hardness in Le Buisson-de-Cadouin is 29.2 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
