PFAS in drinking water

31× above our health benchmark

Amount found in the water 15.5 ng/L 0.0155 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 Saint-Martin-de-Boscherville, the 4 most closely watched PFAS (PFAS-4) add up to 15.5 ng/L (0.0155 µg/L) at the latest PFAS check on 22 April 2026. That's 31 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 27.5 ng/L (0.0275 µg/L), below the EU legal limit (100 ng/L). 2 checks since 23 June 2025: sum of 20 PFAS up to 27.5 ng/L, sometimes below the detection limit.

Frequently asked questions

Is tap water in Saint-Martin-de-Boscherville safe to drink?

Yes. At the check on 18 June 2026, the tap water in Saint-Martin-de-Boscherville 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 Saint-Martin-de-Boscherville's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 27.5 ng/L. The EU limit is 100 ng/L, so this water is at 27 % of the limit. (below the EU limit)

Does the water in Saint-Martin-de-Boscherville also meet the strictest limits in Europe?

No. The four most harmful PFAS add up to 15.5 ng/L. That is 3.9 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 Saint-Martin-de-Boscherville'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 Saint-Martin-de-Boscherville?

The water hardness in Saint-Martin-de-Boscherville is 27 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
