PFAS in Heidolsheim's tap water: 2 ng/L, 4x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
4× 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 Marckolsheim, on the same distribution network as Heidolsheim (SDEA - SECTEUR MARCKOLSHEIM). 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 Heidolsheim, the 4 most closely watched PFAS (PFAS-4) add up to 2 ng/L (0.002 µg/L) at the latest PFAS check on 16 April 2025. That's 4 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 8 ng/L (0.008 µg/L), below the EU legal limit (100 ng/L). Sampled in Marckolsheim, on the same network. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions
Is tap water in Heidolsheim safe to drink?
Yes. At the check on 11 June 2026, the tap water in Heidolsheim was within every limit tested. “Eau destinée à la consommation humaine conforme aux limites de qualité réglementaires pour les paramètres analysés. La concentration des bactéries revivifiables à 22°C et/ou à 36°C est importante. Elles ne présentent pas de risque pour la santé humaine. Si nécessaire, le distributeur d'eau doit effectuer une purge du réseau d'eau potable.”
How high are PFAS levels in Heidolsheim's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 8 ng/L. The EU limit is 100 ng/L, so this water is at 8 % of the limit. (below the EU limit)
Does the water in Heidolsheim 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 2 ng/L stays below.
How hard is the water in Heidolsheim?
The water hardness in Heidolsheim is 20.5 °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 12 September 2026.
