PFAS in drinking water

4× above our health benchmark

Amount found in the water 2 ng/L 0.002 µg/L · the 4 most harmful PFAS (PFAS-4)
Our health benchmark 0.5 ng/L

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 Brombos, the 4 most closely watched PFAS (PFAS-4) add up to 2 ng/L (0.002 µg/L) at the latest PFAS check on 25 March 2025. That's 4 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 2 ng/L (0.002 µg/L), below the EU legal limit (100 ng/L).

Frequently asked questions

Is tap water in Brombos safe to drink?

Yes. At the check on 6 May 2026, the tap water in Brombos was within every limit tested. Outside a reference value: Coliform bacteria 1 n/(100mL) on 6 May 2026 (reference ≤ 0 mL)). These are indicator parameters with reference values, not legal limits. “Eau d'alimentation conforme aux limites de qualité en vigueur mais non satisfaisante aux références de qualité pour les paramètres bactéries coliformes et germes revivifiables. Il est demandé de remédier à la situation de non-conformités constatées. En attendant, l'eau reste consommable.”

How high are PFAS levels in Brombos's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 2 ng/L. The EU limit is 100 ng/L, so this water is at 2 % of the limit. (below the EU limit)

Does the water in Brombos 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 2 ng/L stays below.

How hard is the water in Brombos?

The water hardness in Brombos is 30.4 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
