PFAS in drinking water

1.38× above our health benchmark

Amount found in the water 0.69 ng/L 0.0007 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 Baulme-la-Roche, the 4 most closely watched PFAS (PFAS-4) add up to 0.69 ng/L (0.0007 µg/L) at the latest PFAS check on 12 November 2025. That's 1.38 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 0.69 ng/L (0.0007 µg/L), below the EU legal limit (100 ng/L).

Frequently asked questions

Is tap water in Baulme-la-Roche safe to drink?

Yes. At the check on 29 July 2026, the tap water in Baulme-la-Roche 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 Baulme-la-Roche's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 0.69 ng/L. The EU limit is 100 ng/L, so this water is at 0.7 % of the limit. (below the EU limit)

Does the water in Baulme-la-Roche 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 0.69 ng/L stays below.

How hard is the water in Baulme-la-Roche?

The water hardness in Baulme-la-Roche is 32 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
