PFAS in Kauffenheim's tap water: 9 ng/L, 18x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
18× 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 Roppenheim, on the same distribution network as Kauffenheim (SDEA - SECTEUR ROESCHWOOG ET ENVIRONS). 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 Kauffenheim, the 4 most closely watched PFAS (PFAS-4) add up to 9 ng/L (0.009 µg/L) at the latest PFAS check on 29 January 2026. That's 18 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 13 ng/L (0.013 µg/L), below the EU legal limit (100 ng/L). Sampled in Roppenheim, on the same network. 2 checks since 24 March 2025: sum of 20 PFAS from 10 ng/L to 13 ng/L. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).
Details and sources
PFAS over time in Kauffenheim
2 PFAS checks since 24 March 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Kauffenheim.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.
| Date | PFAS-4 | Sum of 20 PFAS | Sampled at |
|---|---|---|---|
| 9 ng/L – < 13 ng/L · calculated | 13 ng/L | Roppenheim | |
| 8 ng/L – < 10 ng/L · calculated | 10 ng/L | Rœschwoog |
Calculated values: “<” is an upper bound from published thresholds, “≥” a lower bound, “–” means no published sum or complete measurement. How to read a PFAS result

Frequently asked questions
Is tap water in Kauffenheim safe to drink?
Yes. At the check on 29 January 2026, the tap water in Kauffenheim was within every limit tested. Outside a reference value: Coliform bacteria 4 n/(100mL) on 9 October 2025 (reference ≤ 0 mL)). These are indicator parameters with reference values, not legal limits. “Eau destinée à la consommation humaine conforme aux limites de qualité réglementaires pour les paramètres analysés. Eau d'alimentation ne satisfaisant pas aux références de qualité microbiologique en vigueur en raison de sa concentration en bactéries de type coliformes. La concentration des bactéries revivifiables à 22° C et/ou à 36°C est également importante. Toutefois, en l'absence de to ut autre germe d'origine fécale, la présence de ces bactéries ne présente pas de risque sanitaire pour le consommateur. Il appartient au distributeur d'effectuer un entretien régulier du réseau d'adduction d'eau (désinfection par chloration au niveau du réservoir, purges des canalisations, etc.).”
How high are PFAS levels in Kauffenheim's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 13 ng/L. The EU limit is 100 ng/L, so this water is at 13 % of the limit. (below the EU limit)
Does the water in Kauffenheim also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 9 ng/L. That is 2.3 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 Kauffenheim'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 Kauffenheim?
No hardness value is available for Kauffenheim in this source.
