PFAS in drinking water

None of the 4 most harmful PFAS detected

Amount found in the water < 8 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, 4 ng/L found in total
Our health benchmark 0.5 ng/L

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.

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 Muhlbach-sur-Munster, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 1 October 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: 4 ng/L (0.004 µg/L), below the EU legal limit (100 ng/L). 3 checks since 25 June 2025: sum of 20 PFAS up to 4 ng/L, sometimes below the detection limit.

PFAS over time in Muhlbach-sur-Munster

3 PFAS checks since 25 June 2025, from the published measurements. Samples come from 3 distribution networks. The trend refers to the network “MUHLBACH/MUNSTER ZONE HAUTE”.

“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 Muhlbach-sur-Munster safe to drink?

Yes. At the check on 22 July 2026, the tap water in Muhlbach-sur-Munster was within every limit tested. Outside a reference value: Electrical conductivity 52 µS/cm on 22 July 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité. Eau douce, agressive, très faiblement minéralisée susceptible, dans certaines conditions défavorables (notamment stagnation de l'eau), de dissoudre certains métaux des canalisations. Il est conseillé de ne consommer l'eau du robinet qu'après un écoulement de 15 à 30 secondes. L'absence de canalisation en plomb dans les parties privatives des réseaux doit être vérifiée.”

How high are PFAS levels in Muhlbach-sur-Munster's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 4 ng/L. The EU limit is 100 ng/L, so this water is at 4 % of the limit. (below the EU limit)

Does the water in Muhlbach-sur-Munster 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.

Are PFAS levels rising in Muhlbach-sur-Munster'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 Muhlbach-sur-Munster?

The water hardness in Muhlbach-sur-Munster is 1.1 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
