PFAS in Occagnes's tap water: 10.4 ng/L, 20.8x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
20.8× 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.
Sample taken in Montabard, on the same distribution network as Occagnes (BAILLEUL). 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.
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).
More PFAS than in 96% of the cities we track

Frequently asked questions
Is tap water in Occagnes safe to drink?
Yes. At the check on 2 February 2026, the tap water in Occagnes 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 Occagnes's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 11.4 ng/L. The EU limit is 100 ng/L, so this water is at 11 % of the limit. (below the EU limit)
Does the water in Occagnes also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 10.4 ng/L. That is 2.6 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).
How hard is the water in Occagnes?
The water hardness in Occagnes is 31.9 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
