PFAS in drinking water

No PFAS detected

Amount found in the water < 4 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, none found
Our health benchmark 0.5 ng/L

The lab sees nothing below 4 ng/L, 8 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.

Sample taken in Sainte-Cécile, on the same distribution network as La Baleine (VILLEDIEU OUEST). The health authority samples one tap per network; a network carries the same treated water everywhere.

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 ng/L upward. None reached that limit, so their total is below 4 ng/L rather than zero.

None found. The lab sees nothing below 4 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In La Baleine, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 12 January 2026. The total is below 4 ng/L, the sum of the detection limits and 8 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <SEUIL µg/L, below the EU legal limit (100 ng/L). Sampled in Sainte-Cécile, on the same network. 3 checks since 16 June 2025, sum of 20 PFAS always below the detection limit.

Frequently asked questions

Is tap water in La Baleine safe to drink?

Yes. At the check on 12 January 2026, the tap water in La Baleine was within every limit tested. “L'eau distribuée était, au moment du prélèvement,conforme aux limites bactériologiques. Sur le plan chimique, le paramètre Chlorure de Vinyle Monomère (CVM) a été mesuré à une concentration supérieure à la limite de qualité en vigueur. Sa migration à partir des canalisations en PVC posées avant 1980, est favorisée lorsqu'il y a peu de tirage, ce qui est le cas où le prélèvement a été réalisé. De nouveaux prélèvements ont été demandés afin de déterminer quel tronçon de conduite est susceptible de relarguer du CVM.”

How high are PFAS levels in La Baleine'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 La Baleine also meet the strictest limits in Europe?

As far as this check can tell, yes. None of the four compounds was quantified, so their total is below 4 ng/L, the sum of the laboratory's detection limits, and under Sweden's legal limit of 4 ng/L in force since 2026.

Are PFAS levels rising in La Baleine'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 La Baleine?

The water hardness in La Baleine is 9.5 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?
