PFAS in drinking water

No PFAS detected

Amount found in the water < 4 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 4 ng/L, 8 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 1 ng/L upward. None reached that limit, so their total is below 4 ng/L rather than zero.

None found. The lab sees nothing below 4 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Saint-Germain-Lavolps, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 23 April 2026. The total is below 4 ng/L, the sum of the detection limits and 8 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <SEUIL µg/L, below the EU legal limit (100 ng/L). 3 checks since 22 April 2025, sum of 20 PFAS always below the detection limit.

PFAS over time in Saint-Germain-Lavolps

3 PFAS checks since 22 April 2025, from the published measurements. Samples come from 2 distribution networks. The trend refers to the network “ST GERMAIN LAVOLPS BOURG”.

“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 Saint-Germain-Lavolps safe to drink?

Yes. At the check on 30 July 2026, the tap water in Saint-Germain-Lavolps was within every limit tested. Outside a reference value: pH 5.9 unité pH on 30 July 2026 (reference 6.5–9 unité pH), Electrical conductivity 52.3 µS/cm on 23 July 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Examen conforme aux limites de qualité fixées par le Code de la Santé Publique (Art. R 1321-1 à R 1321-68). Références de qualité non satisf aites pour les paramètres bactériologiques (Présence de Bactéries coli formes) et pH.”

How high are PFAS levels in Saint-Germain-Lavolps's drinking water?

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

Does the water in Saint-Germain-Lavolps also meet the strictest limits in Europe?

As far as this check can tell, yes. None of the four compounds was quantified, so their total is below 4 ng/L, the sum of the laboratory's detection limits, and under Sweden's legal limit of 4 ng/L in force since 2026.

Are PFAS levels rising in Saint-Germain-Lavolps'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 Saint-Germain-Lavolps?

The water hardness in Saint-Germain-Lavolps is 0.8 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
