PFAS in drinking water

6× above our health benchmark

Amount found in the water 3 ng/L 0.003 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.

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 Moncheaux, the 4 most closely watched PFAS (PFAS-4) add up to 3 ng/L (0.003 µg/L) at the latest PFAS check on 9 April 2026. That's 6 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 3 ng/L (0.003 µg/L), below the EU legal limit (100 ng/L). 3 checks since 7 January 2026: PFAS-4 from 2 ng/L to 4 ng/L, averaging 3 ng/L over 12 months. Rising on the main network.

Frequently asked questions

Is tap water in Moncheaux safe to drink?

All the values shown here (9 April 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “Eau d’alimentation présentant des dépassements de la valeur indicative de 0,9 µg/L pour le paramètre Chlorothalonil R471811. Toutefois, cette eau est propre à la consommation humaine car la concentration du pesticide concerné reste inférieure aux valeurs sanitaires.”

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

The total of 20 PFAS ("forever chemicals") was last measured at 3 ng/L. The EU limit is 100 ng/L, so this water is at 3 % of the limit. (below the EU limit)

Does the water in Moncheaux also meet the strictest limits in Europe?

Yes. Even against Europe's strictest legal limit, Sweden's 4 ng/L in force since 2026, the measured value of 3 ng/L stays below.

Are PFAS levels rising in Moncheaux's tap water?

Yes. On the main network, the PFAS-4 sum rose from 2 ng/L (7 January 2026) to 3 ng/L (9 April 2026) across 3 quantified checks. pfasnearme's benchmark is 0.5 ng/L as an annual mean.

How hard is the water in Moncheaux?

The water hardness in Moncheaux is 38.9 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?

All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 12 September 2026.
