PFAS in drinking water

No PFAS detected

Amount found in the water < 4 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, none found
Our health benchmark 0.5 ng/L

The lab sees nothing below 4 ng/L, 8 times our benchmark of 0.5 ng/L. Water above our benchmark would pass this check unnoticed.

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 Buneville, on the same distribution network as Moncheaux-lès-Frévent (BUNEVILLE). 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.

The lab detects each of the four substances from 1 ng/L upward. None reached that limit, so their total is below 4 ng/L rather than zero.

Frequently asked questions

Is tap water in Moncheaux-lès-Frévent safe to drink?

At the latest check, the water was over at least one limit. “Eau d’alimentation non conforme aux limites de qualité en vigueur pour le paramètre nitrates. Il est demandé de remédier à la situation de non-conformité constatée. En attendant, cette eau est déconseillée aux populations sensibles (femmes enceintes, nourrissons) pour des usages alimentaires. Concernant la teneur en ions perchlorates, elle respecte les recommandations de l'arrêté préfectoral du 25 octobre 2012.”

How high are PFAS levels in Moncheaux-lès-Frévent's drinking water?

At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 100 ng/L. The EU limit is 100 ng/L, so this water is under 100 % of the limit. (below the EU limit)

Does the water in Moncheaux-lès-Frévent also meet the strictest limits in Europe?

As far as this check can tell, yes. None of the four compounds was quantified, so their total is below 4 ng/L, the sum of the laboratory's detection limits, and under Sweden's legal limit of 4 ng/L in force since 2026.

How hard is the water in Moncheaux-lès-Frévent?

The water hardness in Moncheaux-lès-Frévent is 35.4 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
