PFAS in drinking water

22× above our health benchmark

Amount found in the water 11 ng/L 0.011 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 Geispolsheim, on the same distribution network as Blaesheim (EUROMETROPOLE - SECTEUR STRASBOURG-SUD). 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 96% of the cities we track

Frequently asked questions

Is tap water in Blaesheim safe to drink?

Yes. At the check on 2 July 2026, the tap water in Blaesheim was within every limit tested. “Eau destinée à la consommation humaine conforme aux limites et aux références de qualité réglementaires pour les paramètres analysés.”

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

The total of 20 PFAS ("forever chemicals") was last measured at 11 ng/L. The EU limit is 100 ng/L, so this water is at 11 % of the limit. (below the EU limit)

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

No. The four most harmful PFAS add up to 11 ng/L. That is 2.8 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).

How hard is the water in Blaesheim?

The water hardness in Blaesheim is 28.1 °f (medium). 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.
