PFAS in Gauciel's tap water: under 6 ng/L, none of the four main PFAS detected

PFAS in drinking water

None of the 4 most harmful PFAS detected

Amount found in the water < 6 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, 19.4 ng/L found in total
Our health benchmark 0.5 ng/L

The lab sees nothing below 6 ng/L, 12 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 Caillouet-Orgeville, on the same distribution network as Gauciel (MISEREY). 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 1 to 2 ng/L upward. None reached that limit, so their total is below 6 ng/L rather than zero.

None found. The lab sees nothing below 6 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Gauciel, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 26 February 2025. The total is below 6 ng/L, the sum of the detection limits and 12 times our 0.5 ng/L benchmark. Sum of 20 PFAS: 19.4 ng/L (0.0194 µg/L), below the EU legal limit (100 ng/L). Sampled in Caillouet-Orgeville, on the same network. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions

Is tap water in Gauciel safe to drink?

Yes. At the check on 23 April 2026, the tap water in Gauciel was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”

How high are PFAS levels in Gauciel's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 19.4 ng/L. The EU limit is 100 ng/L, so this water is at 19 % of the limit. (below the EU limit)

Does the water in Gauciel 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 6 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 Gauciel?

The water hardness in Gauciel is 28.6 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?

All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 12 September 2026.

Same water network

Same distribution network as Gauciel, so in principle the same water.
