PFAS in drinking water

No 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, none found
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 Ballersdorf, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 7 July 2026. 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). 2 checks since 25 June 2025, sum of 20 PFAS always below the detection limit (5 ng/L).

PFAS over time in Ballersdorf

2 PFAS checks since 25 June 2025, from the published measurements.

“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 Ballersdorf safe to drink?

Yes. At the check on 7 July 2026, the tap water in Ballersdorf was within every limit tested. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité. La concentration des bactéries aérobies revivifiables est importante. Celles-ci ne présentent pas de risque pour la santé humaine, en l'absence d'autres germes. Une purge du réseau d'eau potable est conseillée. Eau légèrement agressive, susceptible, dans certaines conditions défavorables, de dissoudre certains métaux des canalisations.”

How high are PFAS levels in Ballersdorf'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 Ballersdorf 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 Ballersdorf'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 Ballersdorf?

The water hardness in Ballersdorf is 25.1 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
