PFAS in the tap water of Bompas (Pyrénées-Orientales): 6 ng/L, 12x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
12× 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 Bompas, the 4 most closely watched PFAS (PFAS-4) add up to 6 ng/L (0.006 µg/L) at the latest PFAS check on 27 April 2026. That's 12 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 17 ng/L (0.017 µg/L), below the EU legal limit (100 ng/L). 2 checks since 23 October 2025: sum of 20 PFAS from 17 ng/L to 23 ng/L.

PFAS over time in Bompas
2 PFAS checks since 23 October 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 |
|---|---|---|
| 6 ng/L | 17 ng/L | |

Frequently asked questions
Is tap water in Bompas safe to drink?
Yes. At the check on 27 July 2026, the tap water in Bompas 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 Bompas's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 17 ng/L. The EU limit is 100 ng/L, so this water is at 17 % of the limit. (below the EU limit)
Does the water in Bompas also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 6 ng/L. That is 1.5 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 Bompas'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 Bompas?
The water hardness in Bompas is 16.7 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
