PFAS in drinking water

36× above our health benchmark

Amount found in the water 18 ng/L 0.018 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.

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 Esches, the 4 most closely watched PFAS (PFAS-4) add up to 18 ng/L (0.018 µg/L) at the latest PFAS check on 29 June 2026. That's 36 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 82 ng/L (0.082 µg/L), below the EU legal limit (100 ng/L). 7 checks since 13 August 2025: PFAS-4 up to 18 ng/L, sometimes below the detection limit.

PFAS over time in Esches

63 PFAS checks since 5 August 2024, from the published measurements. Samples from 4 communes on the same network: it's the same water, so each one applies to Esches. Samples come from 2 distribution networks. The trend refers to the network “VALLEE D'ESCHES”.

“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Frequently asked questions

Is tap water in Esches safe to drink?

All the values shown here (29 June 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”

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

The total of 20 PFAS ("forever chemicals") was last measured at 82 ng/L. The EU limit is 100 ng/L, so this water is at 82 % of the limit. (below the EU limit)

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

No. The four most harmful PFAS add up to 18 ng/L. That is 4.5 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 Esches'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 Esches?

The water hardness in Esches is 32.5 °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 21 September 2026.
