PFAS in Belle-Église's tap water: 4 ng/L, 8x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
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 Méru, on the same distribution network as Belle-Église (VALLEE D'ESCHES). 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 90% of the cities we track

In Belle-Église, the 4 most closely watched PFAS (PFAS-4) add up to 4 ng/L (0.004 µg/L) at the latest PFAS check on 5 May 2026. That's 8 times our 0.5 ng/L health benchmark, exactly at Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 38 ng/L (0.038 µg/L), below the EU legal limit (100 ng/L). Sampled in Méru, on the same network. 2 checks since 2 February 2026: PFAS-4 from 1 ng/L to 4 ng/L. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions
Is tap water in Belle-Église safe to drink?
Yes. At the check on 1 June 2026, the tap water in Belle-Église 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 Belle-Église's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 38 ng/L. The EU limit is 100 ng/L, so this water is at 38 % of the limit. (below the EU limit)
Does the water in Belle-Église 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 4 ng/L stays below.
Are PFAS levels rising in Belle-Église's tap water?
Too few quantified checks to say (2 since 5 August 2024). pfasnearme adds each new publication weekly; a trend needs at least three quantified values. These history statistics use laboratory-published sums only.
How hard is the water in Belle-Église?
The water hardness in Belle-Église is 35.2 °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.
Same water network
Same distribution network as Belle-Église, so in principle the same water.
