PFAS in Frohmuhl's tap water: under 8 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
No PFAS detected
The lab sees nothing below 8 ng/L, 16 times our benchmark of 0.5 ng/L. Water above our benchmark would pass this check unnoticed.
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 Puberg, on the same distribution network as Frohmuhl (HAUTE MODER - EICHEL SUPERIEURE). 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.
The lab detects each of the four substances from 2 ng/L upward. None reached that limit, so their total is below 8 ng/L rather than zero.

None found. The lab sees nothing below 8 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Frohmuhl, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 11 April 2025. The total is below 8 ng/L, the sum of the detection limits and 16 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,005 µg/L, below the EU legal limit (100 ng/L). Sampled in Puberg, on the same network. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Values to watch
These results are close to their legal limit, or over it.
Outside a reference value: Coliform bacteria 3 n/(100mL) on 9 June 2026 (reference ≤ 0 mL)). These are indicator parameters with reference values, not legal limits.

Frequently asked questions
Is tap water in Frohmuhl safe to drink?
Yes. At the check on 9 June 2026, the tap water in Frohmuhl was within every limit tested. Outside a reference value: Coliform bacteria 3 n/(100mL) on 9 June 2026 (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. Toutefois, en l'absence de tout 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 Frohmuhl's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 5 ng/L. The EU limit is 100 ng/L, so this water is under 5 % of the limit. (below the EU limit)
Does the water in Frohmuhl also meet the strictest limits in Europe?
The check cannot say. None of the four compounds was quantified, but the laboratory's detection limits add up to 8 ng/L, above Sweden's legal limit of 4 ng/L in force since 2026, so a value between the two would go unnoticed.
How hard is the water in Frohmuhl?
The water hardness in Frohmuhl is 10.8 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
