PFAS in drinking water

34× above our health benchmark

Amount found in the water 17 ng/L 0.017 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.

Sample taken in Estaires, on the same distribution network as Sainte-Marie-Cappel (EBBLINGHEM). 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).

In Sainte-Marie-Cappel, the 4 most closely watched PFAS (PFAS-4) add up to 17 ng/L (0.017 µg/L) at the latest PFAS check on 2 June 2026. That's 34 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 26 ng/L (0.026 µg/L), below the EU legal limit (100 ng/L). Sampled in Estaires, on the same network. 7 checks since 9 January 2026: PFAS-4 from 10 ng/L to 18 ng/L, averaging 13.14 ng/L over 12 months. Rising on the main network.

Frequently asked questions

Is tap water in Sainte-Marie-Cappel safe to drink?

Yes. At the check on 2 June 2026, the tap water in Sainte-Marie-Cappel 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 Sainte-Marie-Cappel's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 26 ng/L. The EU limit is 100 ng/L, so this water is at 26 % of the limit. (below the EU limit)

Does the water in Sainte-Marie-Cappel also meet the strictest limits in Europe?

No. The four most harmful PFAS add up to 17 ng/L. That is 4.3 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 Sainte-Marie-Cappel's tap water?

Yes. On the main network, the PFAS-4 sum rose from 13 ng/L (9 January 2026) to 17 ng/L (2 June 2026) across 7 quantified checks. pfasnearme's benchmark is 0.5 ng/L as an annual mean. These history statistics use laboratory-published sums only.
