PFAS in Nomain's tap water: 11 ng/L, 22x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
22× 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 Templeuve-en-Pévèle, on the same distribution network as Nomain (CAPPELLE EN PEVELE). 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 Nomain, the 4 most closely watched PFAS (PFAS-4) add up to 11 ng/L (0.011 µg/L) at the latest PFAS check on 7 May 2026. That's 22 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 17 ng/L (0.017 µg/L), below the EU legal limit (100 ng/L). Sampled in Templeuve-en-Pévèle, on the same network. 5 checks since 14 January 2026: PFAS-4 from 7 ng/L to 13 ng/L, averaging 11.2 ng/L over 12 months. Rising on the main network.

Frequently asked questions
Is tap water in Nomain safe to drink?
Yes. At the check on 7 May 2026, the tap water in Nomain 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 Nomain's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 17 ng/L. The EU limit is 100 ng/L, so this water is at 17 % of the limit. (below the EU limit)
Does the water in Nomain also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 11 ng/L. That is 2.8 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 Nomain's tap water?
Yes. On the main network, the PFAS-4 sum rose from 7 ng/L (14 January 2026) to 11 ng/L (7 May 2026) across 5 quantified checks. pfasnearme's benchmark is 0.5 ng/L as an annual mean.
How hard is the water in Nomain?
The water hardness in Nomain is 40.3 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
