PFAS in drinking water

14× above our health benchmark

Amount found in the water 7 ng/L 0.007 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.

Sample taken in Munchhouse, on the same distribution network as Rustenhart (S.I.A.E.P. MUNCHHOUSE ET ENV). 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 Rustenhart, the 4 most closely watched PFAS (PFAS-4) add up to 7 ng/L (0.007 µg/L) at the latest PFAS check on 2 July 2025. That's 14 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 7 ng/L (0.007 µg/L), below the EU legal limit (100 ng/L). Sampled in Munchhouse, on the same network. 2 checks since 28 April 2025: sum of 20 PFAS from 7 ng/L to 17 ng/L. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

PFAS over time in Rustenhart

2 PFAS checks since 28 April 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Rustenhart. Samples come from 2 distribution networks. The trend refers to the network “S.I.A.E.P. MUNCHHOUSE ET ENV”.

“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 Rustenhart safe to drink?

Yes. At the check on 29 July 2026, the tap water in Rustenhart was within every limit tested. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité. La température de l'eau dépasse la référence de qualité.”

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

The total of 20 PFAS ("forever chemicals") was last measured at 7 ng/L. The EU limit is 100 ng/L, so this water is at 7 % of the limit. (below the EU limit)

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

No. The four most harmful PFAS add up to 7 ng/L. That is 1.75 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 Rustenhart's tap water?

Calculated PFAS-4 values are listed in the table. The chart uses laboratory-published sum-of-20 results; there are too few laboratory-published PFAS-4 sums for the existing trend calculation.

How hard is the water in Rustenhart?

The water hardness in Rustenhart is 37.4 °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.

Same water network

Same distribution network as Rustenhart, so in principle the same water.
