PFAS in Dives-sur-Mer's tap water: 42.8 ng/L, 85.6x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
85.6× 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 Dives-sur-Mer, the 4 most closely watched PFAS (PFAS-4) add up to 42.8 ng/L (0.0428 µg/L) at the latest PFAS check on 1 July 2026. That's 85.6 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 68.3 ng/L (0.0683 µg/L), below the EU legal limit (100 ng/L). 6 checks since 17 February 2025: sum of 20 PFAS up to 68.3 ng/L, sometimes below the detection limit.

Details and sources
PFAS over time in Dives-sur-Mer
6 PFAS checks since 17 February 2025, from the published measurements. Samples from 3 communes on the same network: it's the same water, so each one applies to Dives-sur-Mer. Samples come from 2 distribution networks. The trend refers to the network “DIVES SUR MER”.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Frequently asked questions
Is tap water in Dives-sur-Mer safe to drink?
Yes. At the check on 1 July 2026, the tap water in Dives-sur-Mer 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 Dives-sur-Mer's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 68.3 ng/L. The EU limit is 100 ng/L, so this water is at 68 % of the limit. (below the EU limit)
Does the water in Dives-sur-Mer also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 42.8 ng/L. That is 10.7 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 Dives-sur-Mer'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 Dives-sur-Mer?
The water hardness in Dives-sur-Mer is 29.4 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
